          Google 为树莓派 Zero W 发布了基于TensorFlow 的视觉识别套件      Cache   Translate Page   Web Page Cache   

Google 发布了一个 45 美元的 “AIY Vision Kit”,它是运行在树莓派 Zero W 上的基于 TensorFlow 的视觉识别开发套件,它使用了一个带 Movidius 芯片的 “VisionBonnet” 板。

为加速该设备上的神经网络,Google 的 AIY 视频套件继承了早期树莓派上运行的 AIY 项目 的语音/AI 套件,这个型号的树莓派随五月份的 MagPi 杂志一起赠送。与语音套件和老的 Google 硬纸板 VR 查看器一样,这个新的 AIY 视觉套件也使用一个硬纸板包装。这个套件和 Cloud Vision API 是不一样的,它使用了一个在 2015 年演示过的基于树莓派的 GoPiGo 机器人,它完全在本地的处理能力上运行,而不需要使用一个云端连接。这个 AIY 视觉套件现在可以 45 美元的价格去预订,将在 12 月份发货。

这个套件的主要处理部分除了所需要的 树莓派 Zero W 单片机之外 —— 一个基于 ARM11 的 1 GHz 的 Broadcom BCM2836 片上系统,另外的就是 Google 最新的 VisionBonnet RPi 附件板。这个 VisionBonnet pHAT 附件板使用了一个 Movidius MA2450,它是 Movidius Myriad 2 VPU 版的处理器。在 VisionBonnet 上,处理器为神经网络运行了 Google 的开源机器学习库 TensorFlow。因为这个芯片,使得视觉处理的速度最高达每秒 30 帧。

这个 AIY 视觉套件要求用户提供一个树莓派 Zero W、一个 树莓派摄像机 v2、以及一个 16GB 的 micro SD 卡,它用来下载基于 Linux 的 OS 镜像。这个套件包含了 VisionBonnet、一个 RGB 街机风格的按钮、一个压电扬声器、一个广角镜头套件、以及一个包裹它们的硬纸板。还有一些就是线缆、支架、安装螺母,以及连接部件。

有三个可用的神经网络模型。一个是通用的模型,它可以识别常见的 1000 个东西,一个是面部检测模型,它可以对 “快乐程度” 进行评分,从 “悲伤” 到 “大笑”,还有一个模型可以用来辨别图像内容是狗、猫、还是人。这个 1000 个图片模型源自 Google 的开源 MobileNets,它是基于 TensorFlow 家族的计算机视觉模型,它设计用于资源受限的移动或者嵌入式设备。

MobileNet 模型是低延时、低功耗,和参数化的,以满足资源受限的不同使用情景。Google 说,这个模型可以用于构建分类、检测、嵌入、以及分隔。在本月的早些时候,Google 发布了一个开发者预览版,它是一个对 Android 和 iOS 移动设备友好的 TensorFlow Lite 库,它与 MobileNets 和 Android 神经网络 API 是兼容的。

          献给 Debian 和 Ubuntu 用户的一组实用程序      Cache   Translate Page   Web Page Cache   

你使用的是基于 Debian 的系统吗?如果是,太好了!我今天在这里给你带来了一个好消息。先向 “Debian-goodies” 打个招呼,这是一组基于 Debian 系统(比如:Ubuntu、Linux Mint)的有用工具。这些实用工具提供了一些额外的有用的命令,这些命令在基于 Debian 的系统中默认不可用。通过使用这些工具,用户可以找到哪些程序占用更多磁盘空间,更新系统后需要重新启动哪些服务,在一个软件包中搜索与模式匹配的文件,根据搜索字符串列出已安装的包等等。在这个简短的指南中,我们将讨论一些有用的 Debian 的好东西。

Debian-goodies – 给 Debian 和 Ubuntu 用户的实用程序

debian-goodies 包可以在 Debian 和其衍生的 Ubuntu 以及其它 Ubuntu 变体(如 Linux Mint)的官方仓库中找到。要安装 debian-goodies,只需简单运行:

$ sudo apt-get install debian-goodies

debian-goodies 安装完成后,让我们继续看一看一些有用的实用程序。

1、 checkrestart

让我从我最喜欢的 checkrestart 实用程序开始。安装某些安全更新时,某些正在运行的应用程序可能仍然会使用旧库。要彻底应用安全更新,你需要查找并重新启动所有这些更新。这就是 checkrestart 派上用场的地方。该实用程序将查找哪些进程仍在使用旧版本的库,然后,你可以重新启动服务。

在进行库更新后,要检查哪些守护进程应该被重新启动,运行:

$ sudo checkrestart
[sudo] password for sk:
Found 0 processes using old versions of upgraded files

由于我最近没有执行任何安全更新,因此没有显示任何内容。

请注意,checkrestart 实用程序确实运行良好。但是,有一个名为 needrestart 的类似的新工具可用于最新的 Debian 系统。needrestart 的灵感来自 checkrestart 实用程序,它完成了同样的工作。 needrestart 得到了积极维护,并支持容器(LXC、 Docker)等新技术。

以下是 needrestart 的特点:

  • 支持(但不要求)systemd
  • 二进制程序的黑名单(例如:用于图形显示的显示管理器)
  • 尝试检测挂起的内核升级
  • 尝试检测基于解释器的守护进程所需的重启(支持 Perl、Python、Ruby)
  • 使用钩子完全集成到 apt/dpkg 中

它在默认仓库中也可以使用。所以,你可以使用如下命令安装它:

$ sudo apt-get install needrestart

现在,你可以使用以下命令检查更新系统后需要重新启动的守护程序列表:

$ sudo needrestart
Scanning processes...
Scanning linux images...

Running kernel seems to be up-to-date.

Failed to check for processor microcode upgrades.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

好消息是 Needrestart 同样也适用于其它 Linux 发行版。例如,你可以从 Arch Linux 及其衍生版的 AUR 或者其它任何 AUR 帮助程序来安装,就像下面这样:

$ yaourt -S needrestart

在 Fedora:

$ sudo dnf install needrestart

2、 check-enhancements

check-enhancements 实用程序用于查找那些用于增强已安装的包的软件包。此实用程序将列出增强其它包但不是必须运行它的包。你可以通过 -ip–installed-packages 选项来查找增强单个包或所有已安装包的软件包。

例如,我将列出增强 gimp 包功能的包:

$ check-enhancements gimp
gimp => gimp-data: Installed: (none) Candidate: 2.8.22-1
gimp => gimp-gmic: Installed: (none) Candidate: 1.7.9+zart-4build3
gimp => gimp-gutenprint: Installed: (none) Candidate: 5.2.13-2
gimp => gimp-help-ca: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-de: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-el: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-en: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-es: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-fr: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-it: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-ja: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-ko: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-nl: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-nn: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-pt: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-ru: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-sl: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-help-sv: Installed: (none) Candidate: 2.8.2-0.1
gimp => gimp-plugin-registry: Installed: (none) Candidate: 7.20140602ubuntu3
gimp => xcftools: Installed: (none) Candidate: 1.0.7-6

要列出增强所有已安装包的,请运行:

$ check-enhancements -ip
autoconf => autoconf-archive: Installed: (none) Candidate: 20170928-2
btrfs-progs => snapper: Installed: (none) Candidate: 0.5.4-3
ca-certificates => ca-cacert: Installed: (none) Candidate: 2011.0523-2
cryptsetup => mandos-client: Installed: (none) Candidate: 1.7.19-1
dpkg => debsig-verify: Installed: (none) Candidate: 0.18
[...]

3、 dgrep

顾名思义,dgrep 用于根据给定的正则表达式搜索制指定包的所有文件。例如,我将在 Vim 包中搜索包含正则表达式 “text” 的文件。

$ sudo dgrep "text" vim
Binary file /usr/bin/vim.tiny matches
/usr/share/doc/vim-tiny/copyright: that they must include this license text. You can also distribute
/usr/share/doc/vim-tiny/copyright: include this license text. You are also allowed to include executables
/usr/share/doc/vim-tiny/copyright: 1) This license text must be included unmodified.
/usr/share/doc/vim-tiny/copyright: text under a) applies to those changes.
/usr/share/doc/vim-tiny/copyright: context diff. You can choose what license to use for new code you
/usr/share/doc/vim-tiny/copyright: context diff will do. The e-mail address to be used is
/usr/share/doc/vim-tiny/copyright: On Debian systems, the complete text of the GPL version 2 license can be
[...]

dgrep 支持大多数 grep 的选项。参阅以下指南以了解 grep 命令。

4、 dglob

dglob 实用程序生成与给定模式匹配的包名称列表。例如,找到与字符串 “vim” 匹配的包列表。

$ sudo dglob vim
vim-tiny:amd64
vim:amd64
vim-common:all
vim-runtime:all

默认情况下,dglob 将仅显示已安装的软件包。如果要列出所有包(包括已安装的和未安装的),使用 -a 标志。

$ sudo dglob vim -a

5、 debget

debget 实用程序将在 APT 的数据库中下载一个包的 .deb 文件。请注意,它只会下载给定的包,不包括依赖项。

$ debget nano
Get:1 http://in.archive.ubuntu.com/ubuntu bionic/main amd64 nano amd64 2.9.3-2 [231 kB]
Fetched 231 kB in 2s (113 kB/s)

6、 dpigs

这是此次集合中另一个有用的实用程序。dpigs 实用程序将查找并显示那些占用磁盘空间最多的已安装包。

$ dpigs
260644 linux-firmware
167195 linux-modules-extra-4.15.0-20-generic
75186 linux-headers-4.15.0-20
64217 linux-modules-4.15.0-20-generic
55620 snapd
31376 git
31070 libicu60
28420 vim-runtime
25971 gcc-7
24349 g++-7

如你所见,linux-firmware 包占用的磁盘空间最多。默认情况下,它将显示占用磁盘空间的 前 10 个包。如果要显示更多包,例如 20 个,运行以下命令:

$ dpigs -n 20

7. debman

debman 实用程序允许你轻松查看二进制文件 .deb 中的手册页而不提取它。你甚至不需要安装 .deb 包。以下命令显示 nano 包的手册页。

$ debman -f nano_2.9.3-2_amd64.deb nano

如果你没有 .deb 软件包的本地副本,使用 -p 标志下载并查看包的手册页。

$ debman -p nano nano

建议阅读:

8、 debmany

安装的 Debian 包不仅包含手册页,还包括其它文件,如确认、版权和自述文件等。debmany 实用程序允许你查看和读取那些文件。

$ debmany vim

使用方向键选择要查看的文件,然后按回车键查看所选文件。按 q 返回主菜单。

如果未安装指定的软件包,debmany 将从 APT 数据库下载并显示手册页。应安装 dialog 包来阅读手册页。

9、 popbugs

如果你是开发人员,popbugs 实用程序将非常有用。它将根据你使用的包显示一个定制的发布关键 bug 列表(使用 popularity-contest 数据)。对于那些不关心的人,popularity-contest 包设置了一个 cron (定时)任务,它将定期匿名向 Debian 开发人员提交有关该系统上最常用的 Debian 软件包的统计信息。这些信息有助于 Debian 做出决定,例如哪些软件包应该放在第一张 CD 上。它还允许 Debian 改进未来的发行版本,以便为新用户自动安装最流行的软件包。

要生成严重 bug 列表并在默认 Web 浏览器中显示结果,运行:

$ popbugs

此外,你可以将结果保存在文件中,如下所示。

$ popbugs --output=bugs.txt

10、 which-pkg-broke

此命令将显示给定包的所有依赖项以及安装每个依赖项的时间。通过使用此信息,你可以在升级系统或软件包之后轻松找到哪个包可能会在什么时间损坏了另一个包。

$ which-pkg-broke vim
Package <debconf-2.0> has no install time info
debconf Wed Apr 25 08:08:40 2018
gcc-8-base:amd64 Wed Apr 25 08:08:41 2018
libacl1:amd64 Wed Apr 25 08:08:41 2018
libattr1:amd64 Wed Apr 25 08:08:41 2018
dpkg Wed Apr 25 08:08:41 2018
libbz2-1.0:amd64 Wed Apr 25 08:08:41 2018
libc6:amd64 Wed Apr 25 08:08:42 2018
libgcc1:amd64 Wed Apr 25 08:08:42 2018
liblzma5:amd64 Wed Apr 25 08:08:42 2018
libdb5.3:amd64 Wed Apr 25 08:08:42 2018
[...]

11、 dhomepage

dhomepage 实用程序将在默认 Web 浏览器中显示给定包的官方网站。例如,以下命令将打开 Vim 编辑器的主页。

$ dhomepage vim

这就是全部了。Debian-goodies 是你武器库中必备的工具。即使我们不经常使用所有这些实用程序,但它们值得学习,我相信它们有时会非常有用。

我希望这很有用。更多好东西要来了。敬请关注!

干杯!

          用以检查 Linux 内存使用的 5 个命令      Cache   Translate Page   Web Page Cache   

对于 Linux 管理员来说,检查系统内存用量是一个重要的技能。Jack 给出了解决这个问题的五种不同方式。

Linux 操作系统包含大量工具,所有这些工具都可以帮助你管理系统。从简单的文件和目录工具到非常复杂的安全命令,在 Linux 中没有多少是你做不了的。而且,尽管普通桌面用户可能不需要在命令行熟悉这些工具,但对于 Linux 管理员来说,它们是必需的。为什么?首先,你在某些时候不得不使用没有 GUI 的 Linux 服务器。其次,命令行工具通常比 GUI 替代工具提供更多的功能和灵活性。

确定内存使用情况是你可能需要的技能,尤其是某个应用程序变得异常和占用系统内存时。当发生这种情况时,知道有多种工具可以帮助你进行故障排除十分方便的。或者,你可能需要收集有关 Linux 交换分区的信息,或者有关安装的内存的详细信息?对于这些也有相应的命令。让我们深入了解各种 Linux 命令行工具,以帮助你检查系统内存使用情况。这些工具并不是非常难以使用,在本文中,我将向你展示五种不同的方法来解决这个问题。

我将在 Ubuntu 18.04 服务器平台上进行演示,但是你应该在你选择的发行版中找到对应的所有命令。更妙的是,你不需要安装任何东西(因为大多数这些工具都包含 Linux 系统中)。

话虽如此,让我们开始工作吧。

top

我想从最常用的工具开始。top 命令提供正在运行的系统的实时动态视图,它检查每个进程的内存使用情况。这非常重要,因为你可以轻松地看到同一命令的多个示例消耗不同的内存量。虽然你无法在没有显示器的服务器上看到这种情况,但是你已经注意到打开 Chrome 使你的系统速度变慢了。运行 top 命令以查看 Chrome 有多个进程在运行(每个选项卡一个 - 图 1)。

top

图1:top 命令中出现多个 Chrome 进程。

Chrome 并不是唯一显示多个进程的应用。你看到图 1 中的 Firefox 了吗?那是 Firefox 的主进程,而 Web Content 进程是其打开的选项卡。在输出的顶部,你将看到系统统计信息。在我的机器上(System76 Leopard Extreme),我总共有 16GB 可用 RAM,其中只有超过 10GB 的 RAM 正在使用中。然后,你可以整理该列表,查看每个进程使用的内存百分比。

top 最好的地方之一就是发现可能已经失控的服务的进程 ID 号(PID)。有了这些 PID,你可以对有问题的任务进行故障排除(或 kill)。

如果你想让 top 显示更友好的内存信息,使用命令 top -o %MEM,这会使 top 按进程所用内存对所有进程进行排序(图 2)。

top

图 2:在 top 命令中按使用内存对进程排序

top 命令还为你提供有关使用了多少交换空间的实时更新。

free

然而有时候,top 命令可能不能满足你的需求。你可能只需要查看系统的可用和已用内存。对此,Linux 还有 free 命令。free 命令显示:

  • 可用和已使用的物理内存总量
  • 系统中交换内存的总量
  • 内核使用的缓冲区和缓存

在终端窗口中,输入 free 命令。它的输出不是实时的,相反,你将获得的是当前空闲和已用内存的即时快照(图 3)。

free

图 3 :free 命令的输出简单明了。

当然,你可以通过添加 -m 选项来让 free 显示得更友好一点,就像这样:free -m。这将显示内存的使用情况,以 MB 为单位(图 4)。

free

图 4:free 命令以一种更易于阅读的形式输出。

当然,如果你的系统是很新的,你将希望使用 -g 选项(以 GB 为单位),比如 free -g

如果你需要知道内存总量,你可以添加 -t 选项,比如:free -mt。这将简单地计算每列中的内存总量(图 5)。

total

图 5:为你提供空闲的内存列。

vmstat

另一个非常方便的工具是 vmstat。这个特殊的命令是一个报告虚拟内存统计信息的小技巧。vmstat 命令将报告关于:

  • 进程
  • 内存
  • 分页
  • 阻塞 IO
  • 中断
  • 磁盘
  • CPU

使用 vmstat 的最佳方法是使用 -s 选项,如 vmstat -s。这将在单列中报告统计信息(这比默认报告更容易阅读)。vmstat 命令将提供比你需要的更多的信息(图 6),但更多的总是更好的(在这种情况下)。

vmstat

图 6:使用 vmstat 命令来检查内存使用情况。

dmidecode

如果你想找到关于已安装的系统内存的详细信息,该怎么办?为此,你可以使用 dmidecode 命令。这个特殊的工具是 DMI 表解码器,它将系统的 DMI 表内容转储成人类可读的格式。如果你不清楚 DMI 表是什么,那么可以这样说,它可以用来描述系统的构成(以及系统的演变)。

要运行 dmidecode 命令,你需要 sudo 权限。因此输入命令 sudo dmidecode -t 17。该命令的输出(图 7)可能很长,因为它显示所有内存类型设备的信息。因此,如果你无法上下滚动,则可能需要将该命令的输出发送到一个文件中,比如:sudo dmidecode -t 17> dmi_infoI,或将其传递给 less 命令,如 sudo dmidecode | less

dmidecode

图 7:dmidecode 命令的输出。

/proc/meminfo

你可能会问自己:“这些命令从哪里获取这些信息?”在某些情况下,它们从 /proc/meminfo 文件中获取。猜到了吗?你可以使用命令 less /proc/meminfo 直接读取该文件。通过使用 less 命令,你可以在长长的输出中向上和向下滚动,以准确找到你需要的内容(图 8)。

/proc/meminfo

图 8:less /proc/meminfo 命令的输出。

关于 /proc/meminfo 你应该知道:这不是一个真实的文件。相反 /proc/meminfo 是一个虚拟文件,包含有关系统的实时动态信息。特别是,你需要检查以下值:

  • 全部内存(MemTotal
  • 空闲内存(MemFree
  • 可用内存(MemAvailable
  • 缓冲区(Buffers
  • 文件缓存(Cached
  • 交换缓存(SwapCached
  • 全部交换区(SwapTotal
  • 空闲交换区(SwapFree

如果你想使用 /proc/meminfo,你可以连接 egrep 命令使用它:egrep --color'Mem | Cache | Swap'/proc/meminfo。这将生成一个易于阅读的列表,其中包含 MemCacheSwap 等内容的条目将是彩色的(图 9)。

/proc/meminfo

图 9:让 /proc/meminfo 更容易阅读。

继续学习

你要做的第一件事就是阅读每个命令的手册页(例如 man topman freeman vmstatman dmidecode)。从命令的手册页开始,对于如何在 Linux 上使用一个工具,它总是一个很好的学习方法。

          系统管理员的 SELinux 指南:这个大问题的 42 个答案      Cache   Translate Page   Web Page Cache   

获取有关生活、宇宙和除了有关 SELinux 的重要问题的答案

“一个重要而普遍的事实是,事情并不总是你看上去的那样 …” ―Douglas Adams,《银河系漫游指南》

安全、坚固、遵从性、策略是末世中系统管理员的四骑士。除了我们的日常任务之外 —— 监控、备份、实施、调优、更新等等 —— 我们还需要负责我们的系统安全。即使这些系统是第三方提供商告诉我们该禁用增强安全性的系统。这看起来像《碟中碟》中 Ethan Hunt 的工作一样。

面对这种窘境,一些系统管理员决定去服用蓝色小药丸,因为他们认为他们永远也不会知道如生命、宇宙、以及其它一些大问题的答案。而我们都知道,它的答案就是这个 42

按《银河系漫游指南》的精神,这里是关于在你的系统上管理和使用 SELinux 这个大问题的 42 个答案。

  1. SELinux 是一个标签系统,这意味着每个进程都有一个标签。每个文件、目录、以及系统对象都有一个标签。策略规则负责控制标签化的进程和标签化的对象之间的访问。由内核强制执行这些规则。
  2. 两个最重要的概念是:标签化(文件、进程、端口等等)和类型强制(基于不同的类型隔离不同的的进程)。
  3. 正确的标签格式是 user:role:type:level(可选)。
  4. 多级别安全Multi-Level Security(MLS)强制的目的是基于它们所使用数据的安全级别,对进程(域)强制实施控制。比如,一个秘密级别的进程是不能读取极机密级别的数据。
  5. 多类别安全Multi-Category Security(MCS)强制相互保护相似的进程(如虚拟机、OpenShift gears、SELinux 沙盒、容器等等)。
  6. 在启动时改变 SELinux 模式的内核参数有:
    • autorelabel=1 → 强制给系统重新标签化
    • selinux=0 → 内核不加载 SELinux 基础设施的任何部分
    • enforcing=0 → 以许可permissive模式启动
  7. 如果给整个系统重新标签化:

    # touch /.autorelabel 
    # reboot
    

    如果系统标签中有大量的错误,为了能够让 autorelabel 成功,你可以用许可模式引导系统。

  8. 检查 SELinux 是否启用:# getenforce

  9. 临时启用/禁用 SELinux:# setenforce [1|0]

  10. SELinux 状态工具:# sestatus

  11. 配置文件:/etc/selinux/config

  12. SELinux 是如何工作的?这是一个为 Apache Web Server 标签化的示例:

    • 二进制文件:/usr/sbin/httpdhttpd_exec_t
    • 配置文件目录:/etc/httpdhttpd_config_t
    • 日志文件目录:/var/log/httpdhttpd_log_t
    • 内容目录:/var/www/htmlhttpd_sys_content_t
    • 启动脚本:/usr/lib/systemd/system/httpd.servicehttpd_unit_file_d
    • 进程:/usr/sbin/httpd -DFOREGROUNDhttpd_t
    • 端口:80/tcp, 443/tcphttpd_t, http_port_t

    httpd_t 安全上下文中运行的一个进程可以与具有 httpd_something_t 标签的对象交互。

  13. 许多命令都可以接收一个 -Z 参数去查看、创建、和修改安全上下文:

    • ls -Z
    • id -Z
    • ps -Z
    • netstat -Z
    • cp -Z
    • mkdir -Z

    当文件被创建时,它们的安全上下文会根据它们父目录的安全上下文来创建(可能有某些例外)。RPM 可以在安装过程中设定安全上下文。

  14. 这里有导致 SELinux 出错的四个关键原因,它们将在下面的 15 - 21 条中展开描述:

    • 标签化问题
    • SELinux 需要知道一些东西
    • SELinux 策略或者应用有 bug
    • 你的信息可能被损坏
  15. 标签化问题:如果在 /srv/myweb 中你的文件没有被正确的标签化,访问可能会被拒绝。这里有一些修复这类问题的方法:

    • 如果你知道标签:# semanage fcontext -a -t httpd_sys_content_t '/srv/myweb(/.*)?'
    • 如果你知道和它有相同标签的文件:# semanage fcontext -a -e /srv/myweb /var/www
    • 恢复安全上下文(对于以上两种情况):# restorecon -vR /srv/myweb
  16. 标签化问题:如果你是移动了一个文件,而不是去复制它,那么这个文件将保持原始的环境。修复这类问题:

    • 使用标签来改变安全上下文:# chcon -t httpd_system_content_t /var/www/html/index.html
    • 使用参考文件的标签来改变安全上下文:# chcon --reference /var/www/html/ /var/www/html/index.html
    • 恢复安全上下文(对于以上两种情况):# restorecon -vR /var/www/html/
  17. 如果 SELinux 需要知道 HTTPD 在 8585 端口上监听,使用下列命令告诉 SELinux:# semanage port -a -t http_port_t -p tcp 8585

  18. SELinux 需要知道是否允许在运行时改变 SELinux 策略部分,而无需重写 SELinux 策略。例如,如果希望 httpd 去发送邮件,输入:# setsebool -P httpd_can_sendmail 1

  19. SELinux 需要知道 SELinux 设置的关闭或打开的一系列布尔值:

    • 查看所有的布尔值:# getsebool -a
    • 查看每个布尔值的描述:# semanage boolean -l
    • 设置某个布尔值:# setsebool [_boolean_] [1|0]
    • 将它配置为永久值,添加 -P 标志。例如:# setsebool httpd_enable_ftp_server 1 -P
  20. SELinux 策略/应用可能有 bug,包括:

    • 不寻常的代码路径
    • 配置
    • 重定向 stdout
    • 泄露的文件描述符
    • 可执行内存
    • 错误构建的库

    开一个工单(但不要提交 Bugzilla 报告;使用 Bugzilla 没有对应的服务)

  21. 你的信息可能被损坏了,假如你被限制在某个区域,尝试这样做:

    • 加载内核模块
    • 关闭 SELinux 的强制模式
    • 写入 etc_t/shadow_t
    • 修改 iptables 规则
  22. 用于开发策略模块的 SELinux 工具:# yum -y install setroubleshoot setroubleshoot-server。安装完成之后重引导机器或重启 auditd 服务。

  23. 使用 journalctl 去列出所有与 setroubleshoot 相关的日志:# journalctl -t setroubleshoot --since=14:20

  24. 使用 journalctl 去列出所有与特定 SELinux 标签相关的日志。例如:# journalctl _SELINUX_CONTEXT=system_u:system_r:policykit_t:s0

  25. 当 SELinux 错误发生时,使用setroubleshoot 的日志,并尝试找到某些可能的解决方法。例如:从 journalctl 中:

    Jun 14 19:41:07 web1 setroubleshoot: SELinux is preventing httpd from getattr access on the file /var/www/html/index.html. For complete message run: sealert -l 12fd8b04-0119-4077-a710-2d0e0ee5755e
    
    # sealert -l 12fd8b04-0119-4077-a710-2d0e0ee5755e
    SELinux is preventing httpd from getattr access on the file /var/www/html/index.html.
    
    ***** Plugin restorecon (99.5 confidence) suggests ************************
    
    If you want to fix the label,
    /var/www/html/index.html default label should be httpd_syscontent_t.
    Then you can restorecon.
    Do
    # /sbin/restorecon -v /var/www/html/index.html
    
  26. 日志:SELinux 记录的信息全在这些地方:

    • /var/log/messages
    • /var/log/audit/audit.log
    • /var/lib/setroubleshoot/setroubleshoot_database.xml
  27. 日志:在审计日志中查找 SELinux 错误:# ausearch -m AVC,USER_AVC,SELINUX_ERR -ts today

  28. 针对特定的服务,搜索 SELinux 的访问向量缓存Access Vector Cache(AVC)信息:# ausearch -m avc -c httpd

  29. audit2allow 实用工具可以通过从日志中搜集有关被拒绝的操作,然后生成 SELinux 策略允许的规则,例如:

    • 产生一个人类可读的关于为什么拒绝访问的描述:# audit2allow -w -a
    • 查看允许被拒绝的类型强制规则:# audit2allow -a
    • 创建一个自定义模块:# audit2allow -a -M mypolicy,其中 -M 选项将创建一个特定名称的强制类型文件(.te),并编译这个规则到一个策略包(.pp)中:mypolicy.pp mypolicy.te
    • 安装自定义模块:# semodule -i mypolicy.pp
  30. 配置单个进程(域)运行在许可模式:# semanage permissive -a httpd_t

  31. 如果不再希望一个域在许可模式中:# semanage permissive -d httpd_t

  32. 禁用所有的许可域:# semodule -d permissivedomains

  33. 启用 SELinux MLS 策略:# yum install selinux-policy-mls。 在 /etc/selinux/config 中:

    SELINUX=permissive
    SELINUXTYPE=mls
    

    确保 SELinux 运行在许可模式:# setenforce 0

    使用 fixfiles 脚本来确保在下一次重启时文件将被重新标签化:# fixfiles -F onboot # reboot

  34. 创建一个带有特定 MLS 范围的用户:# useradd -Z staff_u john

    使用 useradd 命令,映射新用户到一个已存在的 SELinux 用户(上面例子中是 staff_u)。

  35. 查看 SELinux 和 Linux 用户之间的映射:# semanage login -l

  36. 为用户定义一个指定的范围:# semanage login --modify --range s2:c100 john

  37. 调整用户家目录上的标签(如果需要的话):# chcon -R -l s2:c100 /home/john

  38. 列出当前类别:# chcat -L

  39. 修改类别或者创建你自己的分类,修改如下文件:/etc/selinux/_<selinuxtype>_/setrans.conf

  40. 以某个特定的文件、角色和用户安全上下文来运行一个命令或者脚本:# runcon -t initrc_t -r system_r -u user_u yourcommandhere

    • -t 是文件安全上下文
    • -r 是角色安全上下文
    • -u 是用户安全上下文
  41. 在容器中禁用 SELinux:

    • 使用 Podman:# podman run --security-opt label=disable ...
    • 使用 Docker:# docker run --security-opt label=disable ...
  42. 如果需要给容器提供完全访问系统的权限:

    • 使用 Podman:# podman run --privileged ...
    • 使用 Docker:# docker run --privileged ...

就这些了,你已经知道了答案。因此请相信我:不用恐慌,去打开 SELinux 吧

          小城的数学浪漫:探秘密码学专业会议 TPMPC 2018      Cache   Translate Page   Web Page Cache   

江湖上总流传着盖世神功武林秘籍的传说,言之确凿,然见者颇少,一见不得了,譬如《30 天入门九阳神功》,《21 天精通九阴白骨爪》,此等教程实属罕物,睹之不易,遑论据而拥之,若侥幸习得一二,已属佼佼,转瞬跻身武林大佬。江湖更有甚者,机缘巧合得大师弥留之 paper,譬如《10 年浅谈乾坤大挪移》,《深入理解少林易筋经体系结构》、《1 秒钟入定,手把手教你辟邪剑谱》,《当我们在谈论降龙十八掌时我们在谈论什么》,论文加持,顶级算法开窍开天辟地,难题迎刃而解。

一直以来,江湖中血雨腥风的故事大多跟争抢这些电子书有关,赢者仿似开挂,获少林武学研究院等 paper 而制霸中原武林工程学术界,此非独物,区块链江湖里也流传着不少,其中最酷的一样当属密码学无疑,密码学领域不少 paper 似有相同功效。昔时华之山论剑武功绝,今日区块链当问密码学。

近日 AlphaWallet 就有一篇重磅 paper 诞生,虽不似前述诸绝之伟岸功效,但也可谓区块链之震撼大作,诞生在如何的背景之下?在讲些什么?和密码学的关系是什么?解决了什么问题?可以用来做什么?今天 CTO 韡武先从他的视角带你走马观花,看看今年的密码学会议 TPMPC 2018。而在下一期,我们会正式为大家带来这篇江湖秘籍,AlphaWallet 最新的 Paper 《Attestation on Ethereum》!

01

问剑密码学的会议一般都很神祕,就是没多少人知道,没多少人去,去了没多少人听得懂,但是其密码学成果却是江湖里流传的算法神功秘籍,可能有深远影响。给外行有种像是共济会讨论改造世界。关于区块链,熟悉密码学圈子的人应该都知道这个现象,就是密码学家们完全不谈区块链。区块链是密码学应用和分区计算领域的跨领域成果,现在分布式计算专家很多都改称区块链专家了,密码学还是很本色。TPMPC 就是这样一个密码学会议,今年的 2018 年会在丹麦小城 Århus 举行,我试着带大家一起来探秘这个密码学专业会议了。

02

我住处在 Århus 大学对街。早上 9 点起来全无车声、人声,只有鸟叫。这是因为我在 Århus。Århus 去哥本哈根 3 小时路程,全城仅 27 万居民。这也算城吗?我自问。到这个小城,我用的是渡船。东道主丹麦密码学专家 Tore 是我们的顾问,在港口接我。“你没有坐水上飞机来呀?”他说。原来小国有小国的好处,这里的 CTO 出行坐水上飞机,直接在哥本哈根的河道里起降,一下飞机就在 CBD,价格一两百欧元,省下的时间却不止这个价。“可是 Google Map 上没提供这个信息呀”,我笑着说。

03

这座城没有一个摩天大楼,只有一个博物馆算是有意思的建筑。清泉小楼,乏善可陈。然而此时正有 50 多位密码学家共聚此地,因为这是一个一般麻瓜不知道的朝圣之地——全世界最高水平(按论文算)的 MPC——多方安全计算——研究就诞生在这里。

04

多方安全计算是美籍华人姚期智在我所生的那一年 1982 年创建的领域。他提出了一个在不保密的环境下保持秘密的计算方法,靠它获得了图灵奖。姚期智虽然移居清华,他开创的多方安全计算这个领域却定都在 Århus。完成这项使命转化的是 Ivan Damgård 教授,一位白发而精力充沛的教授,行业界的一个传奇人物,生于斯长于斯的丹麦人,也是这场会议的主持人。姚期智在清华现在主要做复杂系统,研究&ldquo 与 NP”这样的问题,但是不忘他的密码学遗产,仍然促成清华跟 Århus 合资建立了研究中心。

05

我住在一个胚胎人工培养专家家里。他给我解释了他的工作,我没听懂。我于是给他解释我此行的目的,到西方取经,这“经”是多方安全计算的一些成果,在很多在区块链场景中,尤其是钱包中,很重要。我先试着给他讲了区块链是如何解决“可信”的问题,而“保密”的问题却悬而末决,需要结合 MPC 才能解决很多应用场景。他听完后表示懂得跟我懂的人胚胎知识差不多。

于是我换了个讲法:“比如说苹果在做 ApplePay,如果美国政府想要用户的支付数据,苹果公司对用户和政府两面都不敢得罪怎么办?如果使用 MPC,苹果就可以说:我们其实自己也不知道。”胚胎专家表示说他懂了。

唉,为了能讲懂,只好讲的不准确。其实我刚才的例子不合适,因为苹果服务器要处理支付的结算环节,不知道是不可能的,用了 MPC 也没用。但是像我们做区块链钱包的,结算由区块链做,我们 AlphaWallet 却是可以用 MPC 保护用户的。现在所有的手机以太坊钱包厂商都知道其用户的以太币地址(可以卖给空投商用,相当于韭菜肥料),而我们出于保护用户,不知道我们用户的以太币地址。这种前提下还要往上做功能,需要的正是 MPC 这种特别魔法。

06

熟悉密码学圈子的人应该都知道这个现象,就是密码学家们不谈区块链。区块链是密码学应用和分区计算领域(加游戏理论)的跨领域成果,现在分布式计算专家很多都改称区块链专家了,密码学还是很本色,跟区块链划清界线。一个月前密码学家 Helger Lipmaa 被指是中本聪,他不客气的说他不可能是中本聪,“因为中本聪不是密码学家嘛”——这个掌故可以反映密码学圈的态度。

洁零知识证明,尤其是非交互的简洁零知识证明,既是区块链未来的核心技术,又是目前密码学的重头。这个领域里这些年研究成果倍出,但是领域里的学者都不太喜欢基于零知识证明设计的 ZCash。我遇到一位零知识理论研究专家,一个坚持要求我用法语叫他名字的十分聪明的青年。他对 ZCash 受媒体暴光很不满意:“先知被当成了神”,他说,“ZKSnark 又不是他们 ZCash 发明的。”

07

在工程圈也有不少人参与会议。各大公司的基础技术研发中心都有代表,包括阿里巴巴。一位家喻户晓的国际品牌荷兰研发中心的代表说,韡武,原来你是搞区块链的,我们一天倒晚反对区块链,都快累死了。我说:你的领域如果跟区块链没关系,为什么需要特别地“反对”它呢?我就不反对胚胎人工培养,跟我没关系嘛。他说,现在各公司的管理层风气是这样的,基础技术研究部门不研究区块链会被问责的,这样重要的技术趋势你们都不研究,公司如何在前沿?所以我们必须额外花力气来反对它。我们光是不做区块链是不够的,得出材料论证我们为什么不做区块链,我听了哭笑不得。

08

我在席间问了几个密码学家,说为什么密码学家不喜欢区块链。总的来说,密码学家觉得区块链是密码学的“不好的”应用,炒币很荒唐,公链搞无政府主义很无聊。传统上密码学的发展跟政府需求是密切相关的,Diffie-Hellman 密钥交换协议不知道免去了多少间谍送命,欢迎比特币的无政府主义思想在密码学界并不吃香。有些密码学技术,比如 IBE(Identity Based Encryption)是基于一个极强中心(知道所有人密钥)假设下发展的(今天讲到一个没有这种假设的 IBE,有意思)。那好的应用是什么呢?有位丹麦密码学博士出来说其实你说区块链不好,但是国家做的也不好,现在丹麦政府给公民发的密匙自己都有一份备份,就没有不可抵赖性了。礼失求诸野,政府不好好用密码学,民间先做区块链有什么错呢?


          UKTools:安装最新 Linux 内核的简便方法      Cache   Translate Page   Web Page Cache   

Ubuntu 中有许多实用程序可以将 Linux 内核升级到最新的稳定版本。我们之前已经写过关于这些实用程序的文章,例如 Linux Kernel Utilities (LKU)、 Ubuntu Kernel Upgrade Utility (UKUU) 和 Ubunsys。

另外还有一些其它实用程序可供使用。我们计划在其它文章中包含这些,例如 ubuntu-mainline-kernel.sh 和从主线内核手动安装的方式。

今天我们还会教你类似的使用工具 —— UKTools。你可以尝试使用这些实用程序中的任何一个来将 Linux 内核升级至最新版本。

最新的内核版本附带了安全漏洞修复和一些改进,因此,最好保持最新的内核版本以获得可靠、安全和更好的硬件性能。

有时候最新的内核版本可能会有一些漏洞,并且会导致系统崩溃,这是你的风险。我建议你不要在生产环境中安装它。

建议阅读:

什么是 UKTools

UKTools 意思是 Ubuntu 内核工具,它包含两个 shell 脚本 ukupgradeukpurge

ukupgrade 意思是 “Ubuntu Kernel Upgrade”,它允许用户将 Linux 内核升级到 Ubuntu/Mint 的最新稳定版本以及基于 kernel.ubuntu.com 的衍生版本。

ukpurge 意思是 “Ubuntu Kernel Purge”,它允许用户在机器中删除旧的 Linux 内核镜像或头文件,用于 Ubuntu/Mint 和其衍生版本。它将只保留三个内核版本。

此实用程序没有 GUI,但它看起来非常简单直接,因此,新手可以在没有任何问题的情况下进行升级。

我正在运行 Ubuntu 17.10,目前的内核版本如下:

$ uname -a
Linux ubuntu 4.13.0-39-generic #44-Ubuntu SMP Thu Apr 5 14:25:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

运行以下命令来获取系统上已安装内核的列表(Ubuntu 及其衍生产品)。目前我持有 7 个内核。

$ dpkg --list | grep linux-image

下次你可以调用 do-kernel-upgrade 实用程序来安装新的内核。如果有任何新内核可用,那么它将安装。如果没有,它将报告当前没有可用的内核更新。

$ do-kernel-upgrade
Kernel up to date. Finishing

再次运行 do-kernel-purge 命令以确认。如果发现超过三个内核,那么它将移除。如果不是,它将报告没有删除消息。

$ do-kernel-purge

          Julia 1.0 Released, 2018 State of Rust Survey, Samsung Galaxy Note 9 Launches Today, Margaret Dawson of Red Hat Named Business Role Model of the Year in Women in IT Awards and Creative Commons Awarded $800,000 from Arcadia       Cache   Translate Page   Web Page Cache   

News briefs for August 9, 2018.

Julia 1.0 made its debut yesterday—the "culmination of nearly a decade of work to build a language for greedy programmers". The language's goal: "We want a language that's open source, with a liberal license. We want the speed of C with the dynamism of Ruby. We want a language that's homoiconic, with true macros like Lisp, but with obvious, familiar mathematical notation like Matlab. We want something as usable for general programming as Python, as easy for statistics as R, as natural for string processing as Perl, as powerful for linear algebra as Matlab, as good at gluing programs together as the shell. Something that is dirt simple to learn, yet keeps the most serious hackers happy. We want it interactive and we want it compiled." You can download it here.

The Rust Community announced the 2018 State of Rust Survey, and they want your opinions to help them establish future development priorities. The survey should take 10–15 minutes to complete, and is available here. And, you can see last year's results here.

Samsung Galaxy Note 9 launches today at 11am ET. You can watch the spectacle via Android Central, which will be streaming the live event.

Margaret Dawson, Vice President, Portfolio Product Marketing at Red Hat, was named Business Role Model of the Year at the inaugural Women in IT Awards USA. The awards were organized by Information Age to "redress the gender imbalance by showcasing the achievements of women in the sector and identifying new role models".

Creative Commons was awarded $800,000 from Arcadia (a charitable fund of Lisbet Rausing and Peter Baldwin) to support CC Search, which is "a Creative Commons technology project designed to maximize discovery and use of openly licensed content in the Commons". CC Search, along with Commons Metadata Library and the Commons API, plans to form the Commons Collaborative Archive and Library, a suite of tools that will "make the global commons of openly licensed content more searchable, usable, and resilient, and to provide essential infrastructure for collaborative online communities".


          Astronomy on KDE      Cache   Translate Page   Web Page Cache   

I recently switched to KDE and Plasma as my main desktop environment, so I thought I'd start digging into some of the scientific software available on KDE. First up is KStars, the desktop astronomy program.

KStars probably won't be installed with the standard KDE desktop, so you may need to install it. If you're using a Debian-based distribution, you can install KStars with the following command:


sudo apt-get install kstars

When you first start it, KStars asks for your current location, and then it gives you the option of installing several extra information files to add to the list of objects that KStars knows about and can display. Once those steps are finished, KStars begins with the current sky at the location you entered earlier.

Figure 1. On startup, KStars shows you the current layout of the sky in your location.

So, what can you do with KStars? If you've used programs like Stellarium before, you'll find that you can do the same types of tasks with KStars. You can use your mouse to click and drag the display to change the direction you're facing. The cardinal directions are labeled along the outside of the circle of the sky, and you can zoom in and out to change the field of view. If you see an object you want to examine further, you can double-click it to center it on the display and tag it as the current object of interest.

Depending on what catalogs of data you installed, some of the objects may have more or less information available. For example, selecting the planet Uranus and zooming all the way in shows a reasonably detailed image of the planet, including the ring orientation.

Figure 2. You can easily select and zoom in to objects of interest in KStars.

Quite a few options are available for controlling what's shown in the main window. The toolbar across the top of the window allows you to toggle the following items: stars, deep sky objects, solar system objects, supernovae, satellites, constellation lines, constellation names, constellation art, constellation boundaries, Milky Way, equatorial coordinate grid, horizontal coordinate grid and opaque ground. This allows you to customize the display so that it shows only what you're interested in at the time. The last display option is to toggle the "What's Interesting" pane.

Спустя 9 лет активной разработки, свет увидел язык для инженерных и технических вычислений Julia 1.0!

Авторы языка многие годы работали с такими языками, как R, Matlab, Fortran и Python. Каждый язык, по мнению авторов, имел свои изъяны и недостатки, вследствие чего было решено разработать современный универсальный специализированный язык, который заменит все вышеперечисленные языки в инженерно-технических вычислениях.

          Kubic Project: An Exciting New Direction      Cache   Translate Page   Web Page Cache   

Dear Community,

It’s been over a year since we started the Kubic project, and it’s worth looking back over the last months and evaluating where we’ve succeeded, where we haven’t, and sharing with you all our plans for the future.

A stable base for the future

Much of our success has been in the area generally referred to as MicroOS, the part of the Kubic stack which provides a stable operating system that is atomicly updated for running containers.

Not only is Kubic MicroOS now a fully integrated part of the openSUSE Tumbleweed release process, but our Transactional Update stack has also been ported to regular openSUSE Tumbleweed and Leap.
Based on your feedback the new System Role has been further refined now includes fully automated updates out of the box.

This collaboration is continuing, with many minor changes to the regular openSUSE installation process coming soon based on lessons learned with tuning the installation process in Kubic.

Reviewing our initial premise

We haven’t just been busy on the basesystem. Our efforts with Rootless Containers continue, and you can now use the “Docker-alternative” Podman CRI-O in both Kubic and regular openSUSE. But when considering the Initial Premise of the Kubic project, it’s probably safe to say we’re not where we hoped to be by now.

When we started in May 2017, SUSE were already well underway developing their first version of SUSE CaaS Platform. Alongside the general goal of making Kubic the easiest-to-live-with community Kubernetes distribution, a big part of the intial premise was to establish itself as a ‘close upstream’ community for SUSE CaaS Platform. In order set things up in a way similar to that you see between openSUSE Tumbleweed and SUSE Linux Enterprise), the plan was to rebase the SUSE CaaS Stack, including the Velum cluster bootstrapping tool onto the shared Kubic/Tumbleweed codebase. After a year, this goal has still proven elusive.

This is for a number of reasons, including the wonderfully fast pace of change of Tumbleweed and aspects of the initial design of SUSE CaaS Platform which was conceptualised for the needs of SUSE’s commercial customers, with the needs of developing within Kubic being an afterthought.
Obviously, this status quo has been tricky for all of us involved in Kubic, with the collective feeling being a desire to simultaneously close the gap between the Kubic and SUSE CaaS codebases, while also keeping up with the ever evolving container landscape, especially surrounding Kubernetes.

The world has shifted

Mentioning Kubernetes, it’s worth considering just how much has changed with kubernetes upstream in the 2 years since SUSE CaaS Platform development began. Back then there was no common tool for setting up and configuring a Kubernetes cluster. This was one of the primary motiviators for creating Velum, a key part of the SUSE CaaS Stack. However these days there are multiple tools, including the increasingly pervasive kubeadm which is used both standalone and as an integrated part of many larger solutions.

Kubeadm has already been actively worked on by a number in the Kubic community, and is also increasingly interesting to the SUSE CaaS developers among the Kubic team as a potentially key part for a new design for future SUSE CaaS Platform versions.

Kubeadm has proven itself as an increasingly mature, and flexible platform for setting up a Kubernetes cluster. There are lots of exciting features already baked into kubeadm and we can really see it’s potential for setting up Kubic Kubernetes clusters quickly, and easily, fitting in with our general goal of having Kubic as the easiest-to-live-with community Kubernetes distribution.

Talking about it among the team, we’re universally excited by this idea of adopting kubeadm as a key part of Kubic, and we’re keen to focus our energies in this direction, which means changes for the Kubic you know today.

Changes inbound!

What does this mean for Kubic users and contributors?

  • We’re going to stop our efforts to syncronise the existing SUSE CaaS Stack on Kubic. The existing Admin, Worker, and Unconfigured system roles will be removed soon.
  • We’re going to focus on getting kubeadm fully working as a first-class solution on Kubic. You can expect to see new installation options and documentation in this direction soon.
  • The SUSE CaaS Platform team are fully on board with this idea and will be more actively contributing to Kubic, investigating the potential use of kubeadm for future CaaS Platform versions

As you can probably imagine, these changes are likely to be quite major, so please mind any dust or disruption as we refocus Kubic in this new direction. We intend to keep this blog updated to share our progress, but most importantly this is not something we wish to do alone.

We think this new direction is really exciting and we want more contributors to help get involved. So please consider a 4th bullet point to the above list:

  • We’re going to do whatever our contributors do as part of the Kubic project. As an openSUSE Project the overarching philosophy of ‘those who do, decide’ applies. You can help shape Kubic to be the container platform YOU need it to be.

This new direction is just part of that wider story, please contribute not only where you agree with us, but share your ideas and join us so we can explore directions we’re not even looking in yet.

How can I help?

Given our immediate goal of kubeadm integration, one of the easiest ways to get involved is contributing directly to kubeadm upstream.
We have no desire of maintaining lots of Kubic specific patches, we plan to do as much of our work upstream first as possible, so any work you do there on behalf of Kubic will greatly help all of us.
Join the Kubernetes SIG Cluster Lifecycle and engage directly with them. You’ll find us there too, because we’re going to lurk less and engage more ourselves.

When it comes to condensing that upstream code into an integrated solution, we’re going to continue using the openSUSE Build Service as our platform of choice for building packages, containers, and VM images.
Contributing to Kubic will stay much as before, following the regular openSUSE Factory Process.

You can expect to see some packages moving from the existing devel:CaaSP Devel Project to our new Devel Project devel:kubic. This is so we can move those packages in devel:kubic at full speed, while devel:CaaSP can remain focused on the needs of SUSE CaaS Platform.
There will soon also be devel:kubic:containers and devel:kubic:images subprojects where we’ll be baking the new Container and VM images respectively as we figure out what we need there.

This new approach brings with it the added benefit of giving us more freedom than previously to experiment in new directions and add new packages and version as we the community see fit, without needing to worry so much about the impact on our downstream partners.

So if you have any ideas, or just need help to get started contributing, please don’t hesitate to get in touch with us!

We are currently using this Trello board to track and organise our work.
Everyone can see what we’re working on, all can comment, and if you want to join in just comment on the Welcome card or reach out to us via any other means to get added to the board.

We’re really excited to be taking Kubic in this new direction and hope the wider community support us and join in to making Kubic into the coolest, most practical, and most open community Kubernetes platform.

Thanks, and Have a lot of fun!


          openSUSE Leap 42.3 Operating System Support Extended Until June 30, 2019      Cache   Translate Page   Web Page Cache   

Launched on July 26, 2017, the OpenSuSE Leap 42.3 operating system is based on SUSE Linux Enterprise (SLE) 12 Service Pack (SP) 3 and the long-term supported Linux 4.4 kernel series. Like previous openSUSE Leap 42 point releases, openSUSE Leap 42.3 was supposed to receive 18 months of support, until January 2019.

However, both the openSUSE Project and parent company SUSE decided to give users more time to upgrade to the latest openSUSE Leap 15 release, which is based on the SUSE Linux Enterprise (SLE) 15 operating system series, by continuing to deliver updates to the openSUSE Leap 42.3 release, and the openSUSE Leap 42 series, for six more months.

          KDE: Astronomy on KDE, MQTT/GSoC, Konversation Tip      Cache   Translate Page   Web Page Cache   
  • Astronomy on KDE

    I recently switched to KDE and Plasma as my main desktop environment, so I thought I'd start digging into some of the scientific software available on KDE. First up is KStars, the desktop astronomy program.

  • LabPlot's MQTT in the finish line

    Hello everyone. GSoC is coming to its end, so I think that I should give a report about what's been done since the last post, and also make a brief evaluation, summary of the project itself.

    As I've written in my last post, the main focus was on improving the quality of the code, cleaning, optimizing and properly documenting it. And also making it more comestible for other developers.

    The next step was searching for bugs and then fixing them. In order to do this properly, I implemented a unit test for the main MQTT related features. This proved to be useful since it helped discover several hidden bugs and errors which were all corrected. The main features, that tests were developed for, are: checking if a topic contains another one, checking if two topics are "common topics" (meaning they only differ at only one level, and are the same size), managing messages, subscribing&unsubscribing.

  • PSA: Use SASL in konversation

    You probably have seen that Freenode has been getting lots of spam lately.

    To protect against that some channels have activated a flag that only allows authenticated users to enter the channel.

    If you're using the regular "nickserv" authentication way as I was doing, the authentication happens in parallel to entering the channels and you'll probably be rejected from joining some.

    Now, the CA’s root is directly trusted by almost all newer versions of operating systems, browsers, and devices. Many older versions, however, still do not directly trust Let’s Encrypt.

    While some of these are expected to be updated to trust the CA, others won’t, and it might take at least five more years until most of them cycle out of the Web ecosystem. Until that happens, Let’s Encrypt will continue to use a cross signature.

    The security flaw was found, accidentally, by security researcher Jens Steube while conducting tests on the forthcoming WPA3 security protocol; in particular, on differences between WPA2's Pre-Shared Key exchange process and WPA3's Simultaneous Authentication of Equals, which will replace it. WPA3 will be much harder to attack because of this innovation, he added.

  • How do tools affect culture?

    Most of the DevOps community talks about how tools don’t matter much. The culture has to change first, the argument goes, which might modify how the tools are used.

    I agree and disagree with that concept. I believe the relationship between tools and culture is more symbiotic and bidirectional than unidirectional. I have discovered this through real-world transformations across several companies now. I admit it’s hard to determine whether the tools changed the culture or whether the culture changed how the tools were used.

  • GPU Accelerated SQL queries with PostgreSQL & PG-Strom in OpenShift-3.10

    In the OpenShift 3.9 GPU blog, we leveraged machine learning frameworks on OpenShift for image recognition. And in the How To Use GPUs with DevicePlugin in OpenShift 3.10 blog, we installed and configured an OpenShift cluster with GPU support. In this installment, we will create a more sophisticated workload on the cluster – accelerating databases using GPUs.

    One of the key parts of any machine learning algorithm is the data (often referred to as the data lake/warehouse, stored as structured, semi-structured or unstructured data).

    A major part of machine learning pipelines is the preparation, cleaning, and exploration of this data. Specifically removing NAs (missing values), transformations, normalization, subsetting, sorting, and a lot of plotting.

  • Reducing the use of non-glibc allocators in Fedora

    Memory allocation for applications is a bit of a balancing act between various factors including CPU performance, memory efficiency, and how the memory is actually being allocated and deallocated by the application. Different programs may have diverse needs, but it is often the kind of workload that the application is expected to handle that determines which memory allocator performs best. That argues for a diversity of memory allocators (and allocation strategies) but, on the other hand, that complicates things for Linux distributions. As a result, Fedora is discussing ways to rein in the spread of allocators used by its packages.

  • Extreme downhill freeriding game 'Descenders' updated with the Ring of Fire update

    The latest update to Descenders adds in the fifth environment to play through named Volcano, which gives you a different way to play. The interesting thing about the Volcano environment, is that you have to unlock it in a very specific way with the developer teasing that "it involves fiery rings of fire". Instead of stunts, this environment uses tectonics instead. In other words, you're in for a bumpy ride.

    In addition to the new environment, which is pretty darn tough to actually reach, they've also added in more new stuff. Along with now having a Linux version that works properly.

    In this update there's also another new bonus level for you to find, they've expanded the "Freeride" mode where you tweak the settings to build your own track to add in the special build crew feature, which gives you certain modifiers like smoother curves or reducing speed wobble. There's also new items for you to unlock as well.

  • It Looks Like A Steam 64-Bit Client Could Finally Be Near

    It looks like Valve could be prepping to finally ship a 64-bit Steam client, possibly coinciding with their long talked about Steam UI/UX overhaul.

    Valve today shipped a new beta release with just one listed change, "Added support for shipping different binaries to 64bit vs 32bit operating systems in Steam self-updater. This support is being added in preparation for future updates."

    The ability for the Steam update to ship different binaries depending upon architecture would be a prerequisite for being able to introduce a 64-bit Steam client while retaining the 32-bit client too... They don't explicitly say it's for shipping a 64-bit Steam client soon, but it's 2018 after all, and there wouldn't be much of a reason to otherwise be adding this capability to the Steam updater...

  • DXVK Introducing Per-Game Configuration Files

    While DXVK is capable of running a great deal of Direct3D 11 games via Vulkan within Wine, a number of games have required various workarounds for either getting the game to properly work in the first place or to run efficiently. Those per-game settings are now being punted off into a per-game configuration system.

  • Voting By Cell Phone Is A Terrible Idea, And West Virginia Is Probably The Last State That Should Try It Anyway

    So we've kind of been over this. For more than two decades now we've pointed out that electronic voting is neither private nor secure. We've also noted that despite this several-decade long conversation, many of the vendors pushing this solution are still astonishingly-bad at not only securing their products, but acknowledging that nearly every reputable security analyst and expert has warned that it's impossible to build a secure fully electronic voting system, and that if you're going to to do so anyway, at the very least you need to include a paper trail system that's not accessible via the internet.

    Applications are the heart of digital business, with code central to the infrastructure that powers it. In order to stay ahead of the digital curve, organizations must move fast and deploy code quickly, which unfortunately is often at odds with stability and security.

    With this in mind, where and how can security fit into the DevOps toolchain? And, in doing so, how can we create a path for successfully deterring threats?

    It’s been a mildly rough week for Wi-Fi security: hard on the heels of a WPA2 weakness comes a programming cockup in the wpa_supplicant configuration tool used on Linux, Android, and other operating systems.

    The flaw can potentially be exploited by nearby eavesdroppers to recover a crucial cryptographic key exchanged between a vulnerable device and its wireless access point – and decrypt and snoop on data sent over the air without having to know the Wi-Fi password. wpa_supplicant is used by Linux distributions and Android, and a few others, to configure the Wi-Fi for computers, gadgets, and handhelds.

  • How the 60-evdev.hwdb works

    libinput made a design decision early on to use physical reference points wherever possible. So your virtual buttons are X mm high/across, the pointer movement is calculated in mm, etc. Unfortunately this exposed us to a large range of devices that don't bother to provide that information or just give us the wrong information to begin with. Patching the kernel for every device is not feasible so in 2015 the 60-evdev.hwdb was born and it has seen steady updates since. Plenty a libinput bug was fixed by just correcting the device's axis ranges or resolution. To take the magic out of the 60-evdev.hwdb, here's a blog post for your perusal, appreciation or, failing that, shaking a fist at. Note that the below is caller-agnostic, it doesn't matter what userspace stack you use to process your input events.

          It looks like T-Mobile’s TV service could be about to launch      Cache   Translate Page   Web Page Cache   
Late last year, T-Mobile acquired a small pay TV company called Layer3, which offers a cable-esque TV service in a handful of markets around the US. At the time,  T-Mobile debuted the acquisition in its usual splashy way, saying that “we’re gonna fix the pain points and bring real choice to consumers across the country,” with some vague plan to have a cheap service with 250 channels. Since last December, T-Mobile's focus has shifted to pushing through its merger with Sprint, and we haven't heard much about its TV plans. But all that could be about to change, as the company is now teasing another Un-carrier event on August 15th, and references to a TV service have popped up on the website. Yesterday, T-Mobile CEO John Legere tweeted a 30-second teaser video showing him boxing up another carrier 'relic,' to go alongside things like limited data plans and, uh, taxes and fees. https://twitter.com/JohnLegere/status/1027178015485116418 A couple other leaks have been spotted that make us think the event on August 15th might have something to do with TV. Ads for Layer3's existing TV service -- which is around $90 a month for a cable-esque bundle, including a set-top box that you hook up to your home internet -- are displaying for some users on T-Mobile's website, depending on your location. A job posting from T-Mobile's website also shows the company is staffing up its engineering team for a TV expansion:
This fast-paced group is seeking self-motivated, go getter Software Embedded Engineers who will be responsible for creating Linux-based operating systems and embedded video applications that power Layer3 TV's next-generation cable service. This individual will be developing the firmware on our consumer Set-Top-Box (STB) and these systems and applications exploit the tremendous potential of our remote controls and users' own mobile devices. Day to day responsibilities would include (not limited to) performing Root-causing production issues with the set-top-box and bug fixing, implementing new product features and maintaining the set-top-box operating system, platform, and video stack.
None of this means that T-Mobile is poised to launch a new TV service next week, but with a launch promised "some time in 2018," it does seem possible.

Even though Bluehost's basic hosting package is on a shared server, the specifications are far from typical when compared to industry standards for shared hosting plans.


Bluehost's servers run on 64-bit Linux distributions. What's more, excessive CPU load and server slowdowns are non-existent on this setup while super-fast site performance is maintained even at peak usage times. These specs are hard to match and leave Bluehost's competitors trailing in their wake.

For back-end administration, Bluehost provide the industry favourite cPanel interface. With its comprehensive features and intuitive design, webmasters have everything they need to easily launch and maintain their sites.

Furthermore, Bluehost's own Page Wizard application enables professional looking Web pages to be created with just a few clicks. Web-based file management and script support for Fantastico are just a few of the many other features that cPanel boasts.

SimpleScripts, Mojo and Fantastico support enables users to quickly install a wide variety of popular software packages such as WordPress, Drupal, and Joomla. Never before has it been so easy to install blogs, forums, image galleries, polls and content management systems.

Fantastico de Luxe popularity amongst webmasters is a testament to its simple operation, and its inclusion in Bluehost's plan adds even more value to their already featured packed offering. For more advanced users who prefer installing scripts manually, Bluehost supports all popular scripting languages including:
  1. CGI
  2. Python
  3. PERL 5
  4. PHP4 & PHP5
  5. Ruby on Rails
  6. CRON jobs, Apache .htaccess and custom php.ini are also supported

Uptime & Performance


Feature-laden, value for money hosting packages are important, but nothing is of greater importance than your web host providing basic network reliability. Claims of 99.9% uptime are all well and good but only the select few can back up their promises with actual data.


Bluehost is proud of their network integrity and list it as one of their key features. No longer do webmasters need to worry about losing business because their site is down. In fact, downtime is one of the most prevalent reasons why site owners shift from mediocre providers to a company like Bluehost who take their commitment to 99.9% up-time very seriously.

Independent testing on a site hosted by Bluehost revealed only thirty minutes of total downtime over a 90-day period. What's really impressive about this result is that, out of the total downtime, all thirty minutes were identified as planned maintenance. Bluehost's planned downtime is always scheduled during periods when Web traffic is off-peak to keep impact to a minimum.

A webmaster will always find any amount of downtime unpalatable but 30 minutes in 90 days equates to 99.93% uptime, which is a highly impressive result. Given that performance is a key factor in the choice of a web hosting provider, we decided to undertake some performance testing of our own. We tested the page load time of the Bluehost homepage .

Bluehost Results: 

Homepage is loaded in 3.4 seconds
Homepage is fully loaded in 5.1 seconds

(Test server region: Dallas, USA. Connection: Cable (5/1 Mbps, 30ms). Date: 11 August 2013)

Help & Support

Bluehost offers customers several ways to access their technical support, one of which is the Bluehost Help Center. The Help Center contains a complete database of troubleshooting issues and fixes, together with instructions for hundreds of site-management tasks. It's the quickest and easiest way to get minor issues resolved.
Alternatively, clients with more complex problems can submit a help ticket through the Help Center and will receive email or live support as needed. Tickets are always answered in less than 12 hours, with most being addressed within just 1-2 hours.

Lastly, Live Phone support is also offered 24/7. This allows customers to speak directly with a technical expert and have all their questions comprehensively answered. Clients outside of the United States have not been forgotten either with additional phone numbers being provided specifically for them.

For anyone who has a website, it is important to know all the possible options that can improve their website’s performance, and a good web hosting company will help you do just that. You can get reliable hosting plans at official hostiserver.com site. Other than that, the following are six web hosting companies that you should know about.
Hostgator vs Bluehost [Hosting Review 2018]

HostGator Web Hosting

If you want a budget web hosting, then HostGator’s plans are perfect for you. There are no limits on disk space, subdomains, and email accounts. You also get a 99.9% uptime guarantee along with 24/7 customer support. Still, there are some limitations including the fact that you will not be getting a free domain name for a year, and will only be able to operate one website on the Hatchling plan.


4 Best WordPress Web Hosting 2018: Bluehost vs Dreamhost vs Hostgator vs SiteGround

GoDaddy Web Hosting

It is a good all-round service and is well-known, respected and trusted all around the globe. It is the biggest domain name registrar in the world and has tens of millions of domain names in its portfolio. Its cheapest web hosting package starts at $2.49/month when you sign up for a year. You will be offered free backup and restore, an uptime guarantee, unlimited storage along with unlimited bandwidth and a free domain.

Bluehost Web Hosting

Bluehost is User-friendly yet powerful and has a Basic website builder included in its plans. It offers shared hosting from $2.99 monthly, and the WordPress plans start at $20 per month. You also get an automated setup for WordPress. There is also a cPanel-based area that allows expert users to tweak things.

1&1 Web Hosting

1&1 web hosting offers an impressive range of services with the price starting from $0.99 per month, which rises to $8 after the first year. The host also provides some smart freebies like a free domain and unlimited storage with SSL certificates, free web design software, 24/7 email and phone support, a 30-day money-back guarantee, a graphics archive, and a 300Gbps network connectivity.

InMotion Web Hosting

The shared hosting plans start from just $3.99 per month. A good thing about this host is that it provides extra services in its plans that other hosting companies will charge you for, including malware and DDoS protection, and a system of primary backups. You will be provided with both Softaculous panels and cPanel with InMotion’s hosting. The firm’s overall performance levels are well above average, and that is why it is perfect for people who want to see fast-loading websites.

Weebly Web Hosting

Weebly gives you the option of a free plan. You will also get advertisements on your website so you will need to move up to a paid plan if you want to get rid of the ads. The Starter package has no storage limits, and you will be getting a free domain. Some of the plans will give you a lot of features that will allow you to build a high-end web store with support for customer reviews, coupons, and inventory management.

The above-mentioned web hosting companies will boost your website’s performance to a large extent.

IBM Power 9 scales to enterprise server


32 to 192 core for enterprise cloud 

Data and making sense of data is one of the most valuable currencies for the modern enterprise and IBM plays big in that market with its Power 9. Now the company has announced a Power 9 solution for enterprise customers.

Back in May, IBM announced AC922 based machines to target AI and deep learning tasks and the new Power E950 and E980 are targeting incredibly big businesses including government, big banks and the financial sector, oil and bass, energy and utilities, public safety and healthcare. Let's take a moment to think about this. Oil and gas utilities with 80,000 sensors in a facility can produce 15 petabytes of data.

Public safety - just in New York City - generates 520 terabytes of data from surveillance cameras. The energy and utility industry with 680 million+ smart meters produce over 280 petabytes of data while healthcare produces the equivalent of 300 million books of health related data that gets produced, per human, in a lifetime.

Security remains a big concern are there is a likelihood of 28 percent that enterprise data might be breached within the next 24 months with an average cost of data breach in 2017 hitting $3.6 million.

Power Cloud 

Power Cloud has a big play in the modern enterprise, whether we are talking about the private or public cloud. IBM has PowerVR and IBM private cloud with Power VC, Power VC Cloud for SDI and KVM with secure and accelerate live migration. Power 9 is cloud ready, as Power VM is built in to scale out systems and Power 8 and Power 9 support enterprise pools and run seamlessly Linux workloads in the PowerVC private cloud.

The existing Power 9 architecture delivers 2X performance per core compared to a X86 Xeon S, 2.6 times memory per socket, and 1.8 times memory bandwidth per socket. That's not all, as Power 9 offers 2X I/O bandwidth and twice the performance in Crypto engines.

IBM is launching Power Enterprise Systems in Q3 2018, the Power E950 for smaller customers and the Power E980 for bigger players. Power systems for the enterprise combine cloud management with security to cloud and Power 9 performance to enable the most data intensive, mission critical workloads, IBM claims.

99.9996 percent uptime

IBM Power System has been ranked the most reliable for 10 straight years delivering 99.9996 percent uptime.

The Power 9 Eneprise E950 MTM 9040 MR9 comes in 4U form factore and has 2S and 4S configurations. This enables 32, 40, 44 and 48 cores as well as 128 DDR4 DIMM models with a maximum 16TB. The system comes with a built in IBM Power Virtual machine and has 10 slots of PCI Gen 4. It runs AIX and Linux.

Power9E

The bigger brother, called E980 1-4 modes MTM 9080-M9S, comes with 5U system node and a 2U system controller unit with 4S processor sockets per node. Up to 192 cores can be added to such systems with up to 128 DDR4 CDIMMs and up to 64TB memory.

This system also supports built in IBM Power VM and up to 32 PCIe Gen 4  slots for very fast expansion accelerators. The E980 runs AIX, IBM I and Linux.  

Power E950

The Power E950's notable enhancement includes more efficient processor communication, 4X memory capacity up to 16 TB per system and 4TB per socket to improve the performance of large scaling in memory data base applications. The E950 2X on chip crypto engines protect data at rest and in motion. The I/O infrastructure designed for PCIe Gen 4 provides 2X I/O bandwidth and concurrent maintenance to improve throughput and help maintain service levels, IBM claims.

The four integrated NVMe drive slots provide faster and more compact storage,  while the system RAS features are improved with enhanced DC-DC regulator redundancy and full fan concurrent maintenance to provide more reliable power and cooling. Last, but not least, the Power E 950 offers improved cost and serviceability with options for 0 – 2 concurrently maintainable internal storage controllers, IBM claims.

Power E980 for big players

Power E980 offers enterprise class Power 9 processors that provide fast response time and increase system stability. Large scale systems throughput will increase and offer a 4X increase in internode bandwidth. The 2X memory capacity with up to 64TB per system can improve the performance of large scale in memory data base applications.

Just like the E950 there is a 2X IB with PCIe Gen 4, 4 integrated NVMEe slots per CEC. System RAS features are improved with support for Guided FSP and SMP cable installation as well as dynamic de-allocation of SMP cable, ½ bandwidth mode and concurrent repair of SMP cabling in the event of a failure in SMP cabling components. A new distributed system clock design eliminates discrete clock cabling from each system drawer to the system control unit.

Upgrade to Power 9 can save money

IBM also promises that with the migration to Power 9 you can save over 50 percent within 3 years. The Power 7 770 machine with 64 cores, 1TB memory and relative performance of 579 / relative performance per core of 8.2 cost $230,000 in hardware maintenance in three years 24x7 while the software maintenance for the same period should stuck up to $19,000, a total of $420.000 for maintenance.

Power E950 offers 24 to 32 cores with 1TB memory and relative performance of 656 or relative performance per core of 27.3. The hardware would cost $182,000 but the hardware maintenance for three years 24x7 comes included and software maintenance for the same period will end up at $27,000 with total cost of ownership at $209,000.

power9Em

This amounts to nearly 2X performance per core and over 12 percent additional capacity with 60 percent deduction in cores to save on the future software licensing and maintenance. This might be a great play for a private cloud deployment.

Migrating to Power E 980 can save you 50 percent within five years, Big Blue claims.

power9E980

Every E950 and E980 system comes with PowerVM and Cloud Power Virtual Cloud manager, Cloud Management console (CMC) VMware vRealize suite integration. This, says IBM is all "carefully tailored" for the  Power cloud native solution with IBM cloud private as well as dynamic resource management across multiple Power cloud servers with enterprise pools.

The Power 9 enterprise stuff including E950 and E980 offer simplified multi cloud delivered with security and built to scale performance while staying affordable and over all reliable, continues IBM.

          Platforma pod domowy serwer?      Cache   Translate Page   Web Page Cache   

@Zenon_Czarodziej pisze:

Cześć
Jaką platformę polecacie na mały, domowy “serwerek”? Taki na sam początek aby zobaczyć czy to w ogóle przejdzie (czy będziemy korzystać). Więc czego potrzebuje:

Podstawy:

  1. Budżet max 200 zł.
  2. Do 10 użytkowników, przy czym raczej nie jednocześnie (ewentualnie sporadycznie będą wszyscy w tym samym czasie korzystać).
  3. Serwer oparty o Linux
  4. O czym myślę [platformy]:
  • Myślałem, o jakiejś płytce typu Banana Pi, tylko pytanie która (z portem SATA - dysk min. 500 GB)? I ewentualnie gdzie kupić w Warszawie ją? Bo przynajmniej część jest już tak tania, że nie trzeba kupować używek, a jednocześnie będę miał gwarancję itd. .
  • Ewentualnie “coś takiego” na allegro

I jeszcze jak to wyjdzie energetycznie? Taki komputer weźmie w miesiącu max ok 60 zł (ktoś ma konkretniejsze wyliczenia)? a Raspberry Pi z dyskiem (ktoś sprawdzał)?

Ja osobiście o tyle skłaniam się w stronę zwykłego PC, że mam możliwość łatwego podłączenia kilku dysków (i zrobienia RAIDu, nawet programowego), oraz dodatkowych rozszerzeń (typu Tuner TV i będzie to w obrębie jednej bryły bez masy dodatkowych kieszeni, rozdzielaczy USB, itp. . Fakt, że małe rozmiary i mniejszy pobór prądu też kuszą.

Funkcje:

  1. Serwer plików. Fajnie by było z szyfrowaniem plików (najchętniej osobnym dla użytkowników).
  2. DLNA, dla TV, komputerów i komórek. Jak tutaj jest z szyfrowaniem? Ewentualnie streaming telewizji.
  3. VPN
  4. Być może gdzieś się przebije tam przy okazji jakaś strona www, VoIP, czy coś tam innego tego typu, tak dla rodziny.
  5. Program genealogiczny
  • Program typu klient serwer lub strona WWW. Czyli dostęp dla kilku osób, tak aby każdy miał zawsze aktualną bazę rodziny. Jeśli program (nie strona www), miałby możliwość pracy przy utracie połączenia z siecią to było by fajne (własna baza danych offline, którą by synchronizował z “chmurą”. Nie potrzebuje klientów na komórki i tablety.
  • Centralna baza danych “offline” (w przeciwieństwie do podajże np. Family Tree Builder)
    Tak, tak jestem wredną małpą i nie życzę sobie aby moje prywatne mimo wszystko istotne dane latały bez powodu po internetach, nawet mnie o tym nie informując. Tak można wyciąć ruch na firewallu, tak można. Tylko jak można skorzystać z “porządnego” programu, bez takich przyjemnych opcji, to ja to wolę.
  • Przy czym ma mieć bazę bez jakiś większych ograniczeń. Czy może inaczej, możliwość stworzenia drzewa z 50 osób to tak średnio mi pasuje. Limit raczej gdzieś między 100-200 jestem w stanie zaakceptować jeszcze, ale mimo wszystko jest to jednak mało i myślę, że szybko to odczuje więc wolałbym większy.
  • Dobry export (tak ogólnie). Czyli mile widziane generowanie wszelkich tam PDF, SVG itd., oraz drukowanie (wg. różnych rozmiarów papieru).
  • Wygodny interfejs po Polsku.
  • Obsługa wszelkich powiązań rodzinnych typu: wnuczek, synek, brat, dziadek, itd., oraz adoptowany, rozwód [względnie śmierć] i druga żona/mąż z własnym potomstwem i tego typu w możliwe łatwy sposób do zrobienia.
  • Mile widziana obsługa domeny (m.in. użytkownicy/logowanie) do zrobienia w względnie łatwy sposób (można się trochę pomęczyć ale bez przesady).

Na coś jeszcze zwrócić uwagę?

          Le casque de réalité « mixée » de Magic Leap coûte 2 295 $      Cache   Translate Page   Web Page Cache   

Pendant des années, la mystérieuse start-up Magic Leap a vendu du rêve, avec sa technologie de réalité « mixée » qui promettait monts et merveilles. L’heure est désormais venu de livrer la marchandise, puisque comme annoncé il y a quelques semaines, l’entreprise a lancé la commercialisation du Magic Leap One Creator Edition dans six villes aux États-Unis, au prix de 2 295 $.

Images @Cnet.

Pour ce prix, les heureux acheteurs recevront gratuitement (ouf) l’appareil ainsi qu’une petite formation pour se mettre en route. Ils pourront jouer avec le casque Lightwear plutôt imposant, qui est fourni avec le Lightpack, un module filaire à glisser à la ceinture, et un contrôleur.

Le Lightwear embarque un ensemble de capteurs de mouvement et une puce « photonique » qui projette des hologrammes. Le Lightpack est le moteur du dispositif, avec un Tegra X2 de Nvidia, 8 Go de RAM, 128 Go de stockage, une batterie qui tiendra 3 heures, un port USB-C et un port jack (le casque intègre ses propres haut-parleurs).

Le dispositif fonctionne sous Lumen OS, un dérivé de Linux. Il est est livré avec plusieurs logiciels pour mettre le pied à l’étrier : une démo d’un jeu, un navigateur web, une app pour placer des objets virtuels dans son environnement, une messagerie. Une boutique est aussi disponible, le Magic Leap World, et l’entreprise espère que les développeurs seront nombreux à embrasser sa technologie (un portail leur est dédié).

AT&T est par ailleurs partenaire de Magic Leap. Même si le casque ne sait pas accrocher de réseau cellulaire, il sera possible de l’utiliser à l’extérieur dans certains cas. Des démos seront organisées dans les boutiques de l’opérateur américain.

Image @The Verge.

Quelques sites US ont eu la possibilité de tester le casque et force est de constater qu’il y a loin de la coupe aux lèvres : The Verge explique que le casque n’en offre pas vraiment plus que l’HoloLens de Microsoft, qui est disponible depuis plus de deux ans.

Certes, et malgré les apparences, le Lightwear est semble-t-il confortable à porter. Les lentilles du casque intègrent ce qui ressemble à des écrans (les fameuses puces « photoniques ») qui affichent les hologrammes. Le champ de vision de 50° est réduit : en dehors du rectangle de la zone virtuelle, les objets virtuels disparaissent. C’est un problème commun avec l’HoloLens.

Le contrôleur et le Lightpack.

« Ne pas être capable d’avoir une vision complète des objets virtuels dans la pièce est un sérieux handicap », abonde Cnet. Le testeur perdait parfois la trace des choses qu’il ne pouvait pas voir, et les objets virtuels en eux-mêmes ressemblent à des « dessins animés Disney ».

Bref, de ce qui ressort de ces premières prises en main, c’est que ce n’est pas gagné pour Magic Leap. L’entreprise a le soutien de plusieurs poids lourds dont Google, mais il lui faudra du contenu pour s’imposer sur le marché. Or, les développeurs ont déjà beaucoup à faire et à investir dans la réalité augmentée d’Apple, de Google, voire de Microsoft.

          Chrome OS can now install Linux apps from .deb packages      Cache   Translate Page   Web Page Cache   

linux applications are usually distributed in one of two ways - through a software repository, or by downloading an installer package from a website. For example, the Steam download page offers a .deb package for Linux users. Even though Linux app support on Chrome OS is improving rapidly, there has never been an obvious way to install .deb packages - until now.


Chrome OS can now install Linux apps from .deb packages

Opening a .deb file on Chrome OS Canary ( source )

On most Debian-based Linux distributions, users can double-click on .deb packages to install them. This same functionality can now be found in the Chrome OS Canary and Dev channels. You can double-click on any .deb file in the Chrome OS Files app to start the installation process.

Even though it was already possible to install .deb packages through the command line , this will make using Linux on Chrome OS much easier for beginners. Not everyone knows how to use apt-get, but most people know how to google "download steam for linux."

一 从认识操作系统开始 1.1 操作系统简介

我通过以下四点介绍什么操作系统:

操作系统(Operation System,简称OS)是管理计算机硬件与软件资源的程序,是计算机系统的内核与基石; 操作系统本质上是运行在计算机上的软件程序 ; 为用户提供一个与系统交互的操作界面 ; 操作系统分内核与外壳(我们可以把外壳理解成围绕着内核的应用程序,而内核就是能操作硬件的程序)。
前后端必备Linux基础知识大科普
1.2 操作系统简单分类

1.windows:目前最流行的个人桌面操作系统 ,不做多的介绍,大家都清楚。

2.Unix:最早的多用户、多任务操作系统 .按照操作系统的分类,属于分时操作系统。Unix 大多被用在服务器、工作站,现在也有用在个人计算机上。它在创建互联网、计算机网络或客户端/服务器模型方面发挥着非常重要的作用。


前后端必备Linux基础知识大科普

3.linux:Linux是一套免费使用和自由传播的类Unix操作系统.Linux存在着许多不同的Linux版本,但它们都使用了 Linux内核 。Linux可安装在各种计算机硬件设备中,比如手机、平板电脑、路由器、视频游戏控制台、台式计算机、大型机和超级计算机。严格来讲,Linux这个词本身只表示Linux内核,但实际上人们已经习惯了用Linux来形容整个基于Linux内核,并且使用GNU 工程各种工具和数据库的操作系统。

二 初探Linux

2.1 Linux简介

我们上面已经介绍到了Linux,我们这里只强调三点。

类Unix系统: Linux是一种自由、开放源码的类似Unix的操作系统 Linux内核: 严格来说,Linux这个词本身只表示Linux内核 Linux之父: 一个编程领域的传奇式人物。他是Linux内核的最早作者,随后发起了这个开源项目,担任Linux内核的首要架构师与项目协调者,是当今世界最著名的电脑程序员、黑客之一。他还发起了Git这个开源项目,并为主要的开发者。

2.2 Linux诞生简介 1991年,芬兰的业余计算机爱好者Linus Torvalds编写了一款类似Minix的系统(基于微内核架构的类Unix操作系统)被ftp管理员命名为Linux 加入到自由软件基金的GNU计划中; Linux以一只可爱的企鹅作为标志,象征着敢作敢为、热爱生活。

2.3 Linux的分类

Linux根据原生程度,分为两种: 内核版本: Linux不是一个操作系统,严格来讲,Linux只是一个操作系统中的内核。内核是什么?内核建立了计算机软件与硬件之间通讯的平台,内核提供系统服务,比如文件管理、虚拟内存、设备I/O等; 发行版本: 一些组织或公司在内核版基础上进行二次开发而重新发行的版本。Linux发行版本有很多种(ubuntu和CentOS用的都很多,初学建议选择CentOS),如下图所示:

三 Linux文件系统概览 3.1 Linux文件系统简介 在Linux操作系统中,所有被操作系统管理的资源,例如网络接口卡、磁盘驱动器、打印机、输入输出设备、普通文件或是目录都被看作是一个文件。

也就是说在LINUX系统中有一个重要的概念: 一切都是文件 。其实这是UNIX哲学的一个体现,而Linux是重写UNIX而来,所以这个概念也就传承了下来。在UNIX系统中,把一切资源都看作是文件,包括硬件设备。UNIX系统把每个硬件都看成是一个文件,通常称为设备文件,这样用户就可以用读写文件的方式实现对硬件的访问。

3.2 文件类型与目录结构 Linux支持5种文件类型 :
前后端必备Linux基础知识大科普
Linux的目录结构如下:

Linux文件系统的结构层次鲜明,就像一棵倒立的树,最顶层是其根目录:


前后端必备Linux基础知识大科普
常见目录说明: /bin: 存放二进制可执行文件(ls,cat,mkdir等),常用命令一般都在这里; /etc: 存放系统管理和配置文件; /home: 存放所有用户文件的根目录,是用户主目录的基点,比如用户user的主目录就是/home/user,可以用~user表示; /usr : 用于存放系统应用程序; /opt: 额外安装的可选应用程序包所放置的位置。一般情况下,我们可以把tomcat等都安装到这里; /proc: 虚拟文件系统目录,是系统内存的映射。可直接访问这个目录来获取系统信息; /root: 超级用户(系统管理员)的主目录(特权阶级^o^); /sbin: 存放二进制可执行文件,只有root才能访问。这里存放的是系统管理员使用的系统级别的管理命令和程序。如ifconfig等; /dev: 用于存放设备文件; /mnt: 系统管理员安装临时文件系统的安装点,系统提供这个目录是让用户临时挂载其他的文件系统; /boot: 存放用于系统引导时使用的各种文件; /lib : 存放着和系统运行相关的库文件 ; /tmp: 用于存放各种临时文件,是公用的临时文件存储点; /var: 用于存放运行时需要改变数据的文件,也是某些大文件的溢出区,比方说各种服务的日志文件(系统启动日志等。)等; /lost+found: 这个目录平时是空的,系统非正常关机而留下“无家可归”的文件(windows下叫什么.chk)就在这里。 四 Linux基本命令

下面只是给出了一些比较常用的命令。推荐一个Linux命令快查网站,非常不错,大家如果遗忘某些命令或者对某些命令不理解都可以在这里得到解决。

Linux命令大全:man.linuxde.net/

4.1 目录切换命令 cd usr: 切换到该目录下usr目录 cd ..(或cd../): 切换到上一层目录 cd /: 切换到系统根目录 cd ~: 切换到用户主目录 cd -: 切换到上一个所在目录 4.2 目录的操作命令(增删改查) mkdir 目录名称: 增加目录 ls或者ll (ll是ls -l的缩写,ll命令以看到该目录下的所有目录和文件的详细信息):查看目录信息 find 目录 参数: 寻找目录(查) 示例: 列出当前目录及子目录下所有文件和文件夹: find . 在/home目录下查找以.txt结尾的文件名:find /home -name "*.txt" 同上,但忽略大小写: find /home -iname "*.txt" 当前目录及子目录下查找所有以.txt和.pdf结尾的文件:find . ( -name "*.txt" -o -name "*.pdf" )或find . -name "*.txt" -o -name "*.pdf" mv 目录名称 新目录名称: 修改目录的名称(改) 注意:mv的语法不仅可以对目录进行重命名而且也可以对各种文件,压缩包等进行重命名的操作。mv命令用来对文件或目录重新命名,或者将文件从一个目录移到另一个目录中。后面会介绍到mv命令的另一个用法。 mv 目录名称 目录的新位置: 移动目录的位置---剪切(改) 注意:mv语法不仅可以对目录进行剪切操作,对文件和压缩包等都可执行剪切操作。另外mv与cp的结果不同,mv好像文件“搬家”,文件个数并未增加。而cp对文件进行复制,文件个数增加了。 cp -r 目录名称 目录拷贝的目标位置: 拷贝目录(改),-r代表递归拷贝 注意:cp命令不仅可以拷贝目录还可以拷贝文件,压缩包等,拷贝文件和压缩包时不用写-r递归 rm [-rf] 目录: 删除目录(删) 注意:rm不仅可以删除目录,也可以删除其他文件或压缩包,为了增强大家的记忆,无论删除任何目录或文件,都直接使用rm -rf 目录/文件/压缩包 4.3 文件的操作命令(增删改查) touch 文件名称: 文件的创建(增) cat/more/less/tail 文件名称 文件的查看(查) cat: 只能显示最后一屏内容 more: 可以显示百分比,回车可以向下一行,空格可以向下一页,q可以退出查看 less: 可以使用键盘上的PgUp和PgDn向上和向下翻页,q结束查看 tail-10 : 查看文件的后10行,Ctrl+C结束 注意:命令 tail -f 文件 可以对某个文件进行动态监控,例如tomcat的日志文件,会随着程序的运行,日志会变化,可以使用tail -f catalina-2016-11-11.log 监控文件的变化 vim 文件: 修改文件的内容(改) vim编辑器是Linux中的强大组件,是vi编辑器的加强版,vim编辑器的命令和快捷方式有很多,但此处不一一阐述,大家也无需研究的很透彻,使用vim编辑修改文件的方式基本会使用就可以了。 在实际开发中,使用vim编辑器主要作用就是修改配置文件,下面是一般步骤: vim 文件------>进入文件----->命令模式------>按i进入编辑模式----->编辑文件------->按Esc进入底行模式----->输入:wq/q! (输入wq代表写入内容并退出,即保存;输入q!代表强制退出不保存。) rm -rf 文件: 删除文件(删) 同目录删除:熟记 rm -rf 文件 即可 4.4 压缩文件的操作命令 1)打包并压缩文件:

Linux中的打包文件一般是以.tar结尾的,压缩的命令一般是以.gz结尾的。

而一般情况下打包和压缩是一起进行的,打包并压缩后的文件的后缀名一般.tar.gz。 命令: tar -zcvf 打包压缩后的文件名 要打包压缩的文件 其中:

z:调用gzip压缩命令进行压缩

c:打包文件

v:显示运行过程

f:指定文件名

比如:加入test目录下有三个文件分别是 :aaa.txt bbb.txt ccc.txt,如果我们要打包test目录并指定压缩后的压缩包名称为test.tar.gz可以使用命令: tar -zcvf test.tar.gz aaa.txt bbb.txt ccc.txt或:tar -zcvf test.tar.gz /test/

2)解压压缩包: 命令:tar [-xvf] 压缩文件

其中:x:代表解压

示例:

1 将/test下的test.tar.gz解压到当前目录下可以使用命令: tar -xvf test.tar.gz

2 将/test下的test.tar.gz解压到根目录/usr下: tar -xvf xxx.tar.gz -C /usr (- C代表指定解压的位置)

4.5 Linux的权限命令

操作系统中每个文件都拥有特定的权限、所属用户和所属组。权限是操作系统用来限制资源访问的机制,在Linux中权限一般分为读(readable)、写(writable)和执行(excutable),分为三组。分别对应文件的属主(owner),属组(group)和其他用户(other),通过这样的机制来限制哪些用户、哪些组可以对特定的文件进行什么样的操作。通过 ls -l 命令我们可以查看某个目录下的文件或目录的权限

示例:在随意某个目录下ls -l


前后端必备Linux基础知识大科普
第一列的内容的信息解释如下:
前后端必备Linux基础知识大科普

下面将详细讲解文件的类型、Linux中权限以及文件有所有者、所在组、其它组具体是什么?

文件的类型: d: 代表目录 -: 代表文件 l: 代表链接(可以认为是window中的快捷方式) Linux中权限分为以下几种: r:代表权限是可读,r也可以用数字4表示 w:代表权限是可写,w也可以用数字2表示 x:代表权限是可执行,x也可以用数字1表示 文件和目录权限的区别:

对文件和目录而言,读写执行表示不同的意义。

对于文件:
前后端必备Linux基础知识大科普
对于目录:
前后端必备Linux基础知识大科普
在linux中的每个用户必须属于一个组,不能独立于组外。在linux中每个文件有所有者、所在组、其它组的概念。 所有者 一般为文件的创建者,谁创建了该文件,就天然的成为该文件的所有者,用ls ahl命令可以看到文件的所有者 也可以使用chown 用户名 文件名来修改文件的所有者 。 文件所在组 当某个用户创建了一个文件后,这个文件的所在组就是该用户所在的组 用ls ahl命令可以看到文件的所有组 也可以使用chgrp 组名 文件名来修改文件所在的组。 其它组 除开文件的所有者和所在组的用户外,系统的其它用户都是文件的其它组

我们再来看看如何修改文件/目录的权限。

修改文件/目录的权限的命令:chmod

示例:修改/test下的aaa.txt的权限为属主有全部权限,属主所在的组有读写权限, 其他用户只有读的权限

chmod u=rwx,g=rw,o=r aaa.txt
前后端必备Linux基础知识大科普

上述示例还可以使用数字表示:

chmod 764 aaa.txt 补充一个比较常用的东西:

假如我们装了一个zookeeper,我们每次开机到要求其自动启动该怎么办?

新建一个脚本zookeeper 为新建的脚本zookeeper添加可执行权限,命令是:chmod +x zookeeper 把zookeeper这个脚本添加到开机启动项里面,命令是:chkconfig --add zookeeper 如果想看看是否添加成功,命令是:chkconfig --list 4.6 Linux 用户管理

Linux系统是一个多用户多任务的分时操作系统,任何一个要使用系统资源的用户,都必须首先向系统管理员申请一个账号,然后以这个账号的身份进入系统。

用户的账号一方面可以帮助系统管理员对使用系统的用户进行跟踪,并控制他们对系统资源的访问;另一方面也可以帮助用户组织文件,并为用户提供安全性保护。

Linux用户管理相关命令: useradd 选项 用户名:添加用户账号 userdel 选项 用户名:删除用户帐号 usermod 选项 用户名:修改帐号 passwd 用户名:更改或创建用户的密码 passwd -S 用户名 :显示用户账号密码信息 passwd -d 用户名: 清除用户密码

useradd命令用于Linux中创建的新的系统用户。useradd可用来建立用户帐号。帐号建好之后,再用passwd设定帐号的密码.而可用userdel删除帐号。使用useradd指令所建立的帐号,实际上是保存在/etc/passwd文本文件中。

passwd命令用于设置用户的认证信息,包括用户密码、密码过期时间等。系统管理者则能用它管理系统用户的密码。只有管理者可以指定用户名称,一般用户只能变更自己的密码。

4.7 Linux系统用户组的管理

每个用户都有一个用户组,系统可以对一个用户组中的所有用户进行集中管理。不同Linux 系统对用户组的规定有所不同,如Linux下的用户属于与它同名的用户组,这个用户组在创建用户时同时创建。

用户组的管理涉及用户组的添加、删除和修改。组的增加、删除和修改实际上就是对/etc/group文件的更新。

Linux系统用户组的管理相关命令: groupadd 选项 用户组 :增加一个新的用户组 groupdel 用户组:要删除一个已有的用户组 groupmod 选项 用户组 : 修改用户组的属性 4.8 其他常用命令 pwd: 显示当前所在位置 grep 要搜索的字符串 要搜索的文件 --color: 搜索命令,--color代表高亮显示 ps -ef/ps aux: 这两个命令都是查看当前系统正在运行进程,两者的区别是展示格式不同。如果想要查看特定的进程可以使用这样的格式: ps aux|grep redis (查看包括redis字符串的进程) 注意:如果直接用ps((Process Status))命令,会显示所有进程的状态,通常结合grep命令查看某进程的状态。 kill -9 进程的pid: 杀死进程(-9 表示强制终止。) 先用ps查找进程,然后用kill杀掉 网络通信命令: 查看当前系统的网卡信息:ifconfig 查看与某台机器的连接情况:ping 查看当前系统的端口使用:netstat -an shutdown: shutdown -h now: 指定现在立即关机;shutdown +5 "System will shutdown after 5 minutes":指定5分钟后关机,同时送出警告信息给登入用户。 reboot: reboot: 重开机。 reboot -w: 做个重开机的模拟(只有纪录并不会真的重开机)。
          Why Red Hat Invested $250M in CoreOS to Advance Kubernetes      Cache   Translate Page   Web Page Cache   

For the last three years or so, Red Hat has been on a collision course with CoreOS, with both firms aiming to grow their respective Kubernetes platform. On Jan. 30, the competition between the two firms ended, with CoreOS agreeing to be acquired by Red Hat in a $250 million deal.

CoreOS didn't start out as a Kubernetes platform vendor, but then again neither did Red Hat. CoreOS' original innovations were the etcd distributed key value store, a purpose-built container linux operating system
Why Red Hat Invested 0M in CoreOS to Advance Kubernetes
(originally known as CoreOS Linux) and the company's Fleet platform that enabled Docker containers to easily be run as a cluster. In a 2017video interview with ServerWatch CoreOS co-founder and CTO Brandon Philips explained why his company moved on from Fleet and embraced Kubernetes with its Tectonic platform.

Red Hat's OpenShift platform was originally built based on technologyacquiredfrom Platform-as-a-Service vendor Makara in 2010. Red Hat entirely re-worked the platform for its 3.0 release in 2015, re-basing it on Docker and Kubernetes.

While Red Hat OpenShift and CoreOS Tectonic are both based on Kubernetes, they were highly competitive with each other. Though that's not how Red Hat sees it.

"CoreOS' existing commercial products are complementary to existing Red Hat solutions," Matt Hicks, senior vice president, engineering, Red Hat, told ServerWatch . "Our specific plans and timeline around integrating products and migrating customers to any combined offerings will be determined over the coming months."

Hick said that it is Red Hat belief that CoreOS customers will benefit from industry-leading container and Kubernetes solutions, a broad portfolio of enterprise open source software, world-class support and an extended partner network.

CoreOS had been leading the development of the rkt container runtime, which is a rival to Docker-backed containerd runtime. Red Hat has its own effort known as CRI-O, which is based on containerd. CRI-O 1.0 wasreleasedin October 2017.

"rkt has a sustaining community within the Cloud Native Computing Foundation (CNCF) and that won't change," Hicks said. " Red Hat and CoreOS are both committed to furthering the standardization of key container standards to further enterprise adoption, as evidenced by our leadership positions within OCI. Specific product-level decisions will come in the following weeks around future investments."

Why Now?

Red Hat and CoreOS were actively competing against each other in the market. Red Hat CEO Jim Whitehurst has repeatedly made multiple comments in recent months about the financial success OpenShift has had.

"If you believe containerized applications will be kind of how applications are developed in the future, it will be a substantial opportunity," Whitehurstsaidin September 2017. "There is a lot of value in it [OpenShift], because it includes RHEL, it includes a fully supported life cycle Kubernetes and a whole set of management tools, and then, obviously, above that a whole developer tool chain."

Now with CoreOS as part of Red Hat, the value in OpenShift can potentially be expanded even further. Hicks said that CoreOS can expand Red Hat’s technology leadership in containers and Kubernetes and enhance core platform capabilities in OpenShift, Red Hat Enterprise Linux and Red Hat’s integrated container portfolio.

"Bringing CoreOS’s technologies to the Red Hat portfolio can help us further automate and extend operational management capabilities for OpenShift administrators and drive greater ease of use for end users building and managing applications on our platform," Hicks said.

Hicks added that CoreOS’s offerings complement Red Hat’s container solutions in a number of ways:

Tectonic and its investment in the Kubernetes project that it is based on are complementary to Red Hat OpenShift and Red Hat’s own investments in Kubernetes. CoreOS can further extend Red Hat’s leadership and influence in the Kubernetes upstream community and also bring new enhancements to Red Hat OpenShift around automated operations and management.

Container Linux and its investment in container-optimized Linux and automated “over the air” software updates are complementary to Red Hat Enterprise Linux, Red Hat Enterprise Linux Atomic Host and Red Hat’s integrated container runtime and platform management capabilities. Red Hat Enterprise Linux’s content, the foundation of our application ecosystem will remain our only Linux offering. Whereas, some of the delivery mechanisms pioneered by Container Linux will be reviewed by a joint integration team and reconciled with Atomic.

Quay brings expanded registry capabilities that can both enhance OpenShift’s integrated registry component and the Red Hat Container Catalog and be used as a standalone component.

In the final analysis, with Red Hat's acquisition of CoreOS, the big shift is that there is one less competitor in the Kubernetes landscape and the biggest player, just got bigger.

          My Own Car System, Rear Camera, Offline Maps & Routing, Map Matching with ...      Cache   Translate Page   Web Page Cache   

This is my journey building an open source car system with Go & Qt, rear camera, live OpenGL map …

Cross compilation

In Part I, I had to patch qtmultimedia for the camera to work, but Qt compilation is ressource hungry, same goes for the osrm compilation, the memory of the Raspberry Pi is too small.

I had to to set up a cross compilation system in my case for armv7h.

QML Development

Since most of the application is in QML , I’ve used the c++ main.cpp launcher as long as possible for the development.

At the moment I needed to inject data from the outside world (like the GPS location) to QML via Qt, so I switched to Go using therecipe Qt Go bindings .

The Go bindings project is young but the main author is really active fixing issues.

It makes desktop applications easy to code without the assle of C++ (at least for me).

About QML, by separating the logic and forms using .qml.ui you still can edit your views with Qt Creator :

That’s just the narrative, truth is Creator is really buggy and I edited the ui files by hand most of the time.

I worked with Interface Builder on iOS for years, Qt is painful, lack of decent visual editor for QML really hurts.

Serving the map without internet access

In Part I, we talked about OpenMapTiles and OpenGL rendering, but I needed a web server capable of reading MBTiles format and serving the necessary assets for the map to be rendered.

I’ve created mbmatch in Go for that purpose so mocs can render the map without Internet access, it will also map match the positions in the future.

Experimenting with another touch screen

I’m using a less performant but smaller LANDZO 5 Inch Touch Display 800x480

This touchscreen is handled as a one button mouse.

It can be calibrate using tslib ts_calibrate command.

Then in your start env tell Qt to use tslib.

TSLIB_TSDEVICE=/dev/input/event0 QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0 QT_QPA_FB_TSLIB=1 GPS

Like I said inpart I, the linux gps daemons are using obscure and over complicated protocols so I’ve decided to write my own gps daemon in Go using a gRPC stream interface. You can find it here .

I’m also not satisfied with the map matching of OSRM for real time display, I may rewrite one using mbmatch .

POIs

I’ve started POIs lookups with full text search and geo proximity using bleve by exposing an API compatible with the OSM API so it can be used directly by QML Locations.

Night Map

I’m a huge fan of the Solarized colors , I’ve made a style for the map you can find it here

          If for some reason you're still using TKIP crypto on your Wi-Fi, ditch it Lin ...      Cache   Translate Page   Web Page Cache   

It’s been a mildly rough week for Wi-Fi security: hard on the heels ofa WPA2 weakness comes a programming cockup in the wpa_supplicant configuration tool used on linux, Android, and other operating systems.

The flaw can potentially be exploited by nearby eavesdroppers to recover a crucial cryptographic key exchanged between a vulnerable device and its wireless access point and decrypt and snoop on data sent over the air without having to know the Wi-Fi password. wpa_supplicant is used by Linux distributions and Android, and a few others, to configure the Wi-Fi for computers, gadgets, and handhelds.

This key is used in networks that employ EAPOL (Extensible Authentication Protocol over LAN). The good news is that no more than around 20 per cent of wireless networks will be vulnerable, it is estimated, because the attack requires TKIP and WPA2 to be in use and no one should be using TKIP in 2018 .

In this paper [PDF], “Symbolic Execution of Security Protocol Implementations: Handling Cryptographic Primitives," to be presented at the Usenix Workshop on Offensive Technologies symposium next week , Mathy Vanhoef and Frank Piessens of the Katholieke Universiteit Leuven in Belgium, explained how a decryption oracle can be used to perform unauthorized decryption of wireless network traffic. Doing back, er, bit flips

In this Twitter thread , Vanhoef summarized what’s going on: “The problem is that data is decrypted with RC4, and then processed, without its authenticity being checked. So you can flip bits, see how to client reacts, and based on that, recover plaintext.”

And as wpa_supplicant maintainer Jouni Malinen explained in his advisory on Wednesday: “It is possible for an attacker to modify the [EAPOL] frame in a way that makes wpa_supplicant decrypt the key data field without requiring a valid MIC [Message Integrity Code] value in the frame, ie: without the frame being authenticated.”

Malinen added that WPA2 shouldn’t be set up with TKIP as the latter isknown to be weak anyway. However, as Vanhoef noted, there's still people out there using this combination. So, in short, just ensure TKIP is disabled. Malinen added that to recover group encryption keys, a snooper would have to make 128 connection attempts per octet, because an attacker’s bit-flips will make the four-way authentication handshake fail. Not only is this slow, it could crash the access point under attack.

Vanhoef conceded that an attack would be slow to pull off, taking around 20 minutes per byte recovered. “Several clients can be attacked in parallel, but it's still a non-trivial attack. Patch, but don't worry too much,” he said.

Nonetheless, the wpa_supplicant team has taken the bug seriously, and developed a fix that should hopefully or eventually trickle down to netizens. Access points and devices will need an update for networks to be free from the flaw. Malinen said if possible, affected users should just kill off TKIP in their networks.

The wpa_supplicant maintainers have pushed out a hotfix here , and the next version, 2.7, will carry the fix. Vanhoef has a proof-of-concept of his attack over on GitHub .

          使用 setfacl 管理文件的访问控制列表ACL      Cache   Translate Page   Web Page Cache   

如果你是在一个大型组织,你运行了 NFS 或者 Samba 服务给不同的用户,你将会需要灵活的挑选并设置很多复杂的配置和权限去满足你的组织不同的需求。linux(以及其他Unix等POSIX兼容的操作系统)有一个被称为访问控制列表(ACL)的权限控制方法,它是一种权限分配之外的普遍范式。例如,默认情况下你需要维护3个权限组:owner、group和other。


使用 setfacl 管理文件的访问控制列表ACL
使用ACL后,你可以设置权限给其他用户或组,而不单只是简单的”other”。可以允许指定的用户A、B、C拥有写权限而不再是让他们整个组拥有写权限。

ACL支持多种Linux文件系统,包括ext2, ext3, ext4, XFS, Btrfs等。如果你不确定你的文件系统是否支持ACL,请参考文档。

首先我们需要安装工具来管理ACL。在 Debian 系统中,执行命令: sudo apt-get install acl

ACL 使用样例

ACL即Access Control List,主要的目的是提供传统的 owner, group, others 的 read, write, execute 权限之外的具体权限设置,ACL可以针对单一用户、单一文件或目录来进行r,w,x的权限控制,对于需要特殊权限的访问控制有一定帮助。例如,某一个文件不让单一的某个用户访问。

ACL使用两个命令来对其进行控制:

getfacl:取得某个文件/目录的ACL设置项目 setfacl:设置某个文件/目录的ACL设置项目

setfacl 的命令参数:

-m:设置后续acl参数

-x:删除后续acl参数

-b:删除全部的acl参数

-k:删除默认的acl参数

-R:递归设置acl,包括子目录

-d:设置默认acl

使用样例:创建一文件test,将其权限修改为777,并查看其默认ACL权限配置

[root@ debian.cn ~]# touch /opt/test
[root@ debian.cn ~]# chmod 777 /opt/test
[root@ debian.cn ~]# getfacl /opt/test //获得文件的ACL权限
getfacl: Removing leading '/' from absolute path names
# file: opt/test //文件名
# owner: root //文件所属者
# group: root //文件所属组
user::rwx //文件所属者权限
group::rwx //同组用户权限
other::rwx //其它者权限

可以看到其它者的权限也是可读可写可执行,可以自行测试。现在我们修改其ACL策略,使用户 code 只有读取的权限

[root@ debian.cn ~]# setfacl -m u:code:r /opt/test
[root@ debian.cn ~]# ls -l /opt/test
-rwxrwxrwx+ 1 root root 1 Apr 11 07:25 /opt/test //可以看到权限的最后多了一个 "+" 号

现在再次查看一下此文件的ACL属性:

[root@ debian.cn ~]# getfacl /opt/test
getfacl: Removing leading '/' from absolute path names
# file: opt/test
# owner: root
# group: root
user::rwx
user:code:r-- //可以看到code单独的权限为r--
group::rwx
mask::rwx
other::rwx

注意:code 的权限并不是只根据ACL配置来决定的,它是由code用户基本权限与配置的ACL权限的“与”运算决定的,即other:rwx 与 code:r = code:r

可以使用code用户,测试是否可写。在写文件时,会出现 INSERT ― W10: Warning: Changing a readonly file提示。

除了对单个用户进行设置外,还可以对用户组、有效权限(mask)进行设置。

如对用户组设置: g:[用户组]:[rwx]

注:有效权限(mask) 即用户或组所设置的权限必须要存在于mask的权限设置范围内才会生效

如上面的/opt/test文件,已经有了可读权限,如果我们把它的有效权限修改为只有写权限,则设置的 acl 权限不在有效权限之内,则用户code就不可能再查看/opt/test文件中的内容了。

[root@ debian.cn ~]# setfacl -m m:w /opt/test //设置有效权限为只写

可以查看/opt/test acl属性

[root@ debian.cn ~]# getfacl /opt/test
getfacl: Removing leading '/' from absolute path names
# file: opt/test
# owner: root
# group: root
user::rwx
user:code:r-- #effective:---
group::rwx #effective:-w-
mask::-w- //可以看到有效权限已经修改成功
other::rwx

使用code用户查看文件内容,首先使用root用户写入一些内容,会使测试更加直观

[root@ debian.cn ~]# echo "this is a test getfacl " >/test

          Linux 通过 mac地址 查询 ip 和 清除arp 缓存      Cache   Translate Page   Web Page Cache   

问题重述:

今天,突然找不到vm 的ip 了,但是可以从网卡状态上看到其 mac 地址,并且确定主机是启动状态,网络状态良好(后来发现因为子网掩码的问题,导致虚拟机和网关之间不通信,从而导致其他网络的主机不能访问,这个是另一个问题了。)

所以我们需要通过vm 的mac 地址来获取到vm 具体的 ip了。

(1)linux中获取mac 地址可以通过 arp -a 命令,通过 grep 输出对应的mac 地址

(2)通过输出 /proc/net/arp 文件,通过 grep 筛选来获取对应的 ip 地址。

(3)使用 ip neigh show, 配合 grep 来筛选对应的 ip 地址。

前提:你所查的主要要和您属于同以太网下。

如果有其他方法,请您在博文下面进行留言交流:

[root@linuxmi ~]# cat /proc/net/arp | grep 00:16:3e:10:7c:60

10.66.10.155 0x1 0x2 00:16:3e:10:7c:60 * ovirtmgmt

10.66.10.153 0x1 0x0 00:16:3e:10:7c:60 * ovirtmgmt

[root@linuxmi ~]# ip neigh show | grep 00:16:3e:10:7c:60

10.66.10.155 dev ovirtmgmt lladdr 00:16:3e:10:7c:60 REACHABLE

这里面 我进行查到了两个对应的 ip 地址,应该是arp 缓存的问题。实际我们 测试机器,之前 曾改变过ip 地址,从 153-> 155 所以导致了 ip 地址的变化。

但是使用 ip neigh show 查出的 ip 地址较为准确。

清除arp 缓存命令:

Desktop sudo ip neigh flush dev wlp3s0

上面命令是按照网卡设备来进行清除的网络地址。还有很多其他的选项,具体内容可以具体来选择。

          CLI invocation if KiCAD commands      Cache   Translate Page   Web Page Cache   

There is no direct CLI invocation in Kicad to do this sort of thing but PCBNew is scriptable and has a Python abstraction layer. This is in a state of flux at present and scripting is not available on all platforms/versions. However, in macOS, you are in luck - both in 4.0.7 and 5.0.1 support python scripting. There is still a bit of finangelling required to get this to work.

There is some useful material about Python scripting here (but bear in mind the comments about the current ongoing changes).

The following script will work on macOS and will generate gerbers. Save the script somewhere in your path or run it in situ. Change the path where you want the output directory (line 11) Invoke it from the command line with the path to a *.kicad_pcb file e.g.

./plotter.py ~/EDA_Workspace/Projects/Thermocouple_datalogger/Ver_5V/ThermocoupleLogger.kicad_pcb

Script;

bitmap2component will only (AFAIK) take bitmap (bmp) images and convert them. You would have to convert from jpg to BMP first. The library format converts to polylines. I think you could probably do this with Inkscape but haven’t tried.

EDIT Further thought - you could try using a workflow based on bmp -> svg using the excellent potrace utility [http://potrace.sourceforge.net] and then converting your svg to a footprint using svg2mod script https://github.com/mtl/svg2mod.

It should be easy enough to tie those together with a bit of bash fu if you have a lot of bitmaps to do.

Valve is certainly not the last software developer in the world to still offer 32-bit versions of its applications, but as the world kind of moved to 64-bit apps and operating systems, they will be forced to that too very soon.

Apple already forced their hands with the upcoming macOS Mojave 10.14 operating system, which will be available this fall, by deprecating support for 32-bit apps and urging application developers to move to 64-bit apps.

          Adventures in 3D Printing      Cache   Translate Page   Web Page Cache   

Originally posted on: http://blog.loethen.net/cwilliams/archive/2017/02/13/235740.aspx

Background:  I have a Micro 3D Printer, which runs (usually headless) off an OctoPrint server, running on a Raspberry Pi 3.  I moved a few months ago and the whole setup sat in a box until this weekend.

I start setting everything up again. I'm not a Linux expert by any means, but this thing is relatively plug and play, when it works. Fire everything up... led lights come on, it’s running headless (no monitor or keyboard) but I think it’s booted ok. Off to a good start.

The OctoPrint server presents a nice web interface you can use to control your printer, so I try to connect from my desktop.  No luck. 

Drag out a monitor, hmm... VGA, ok... dig around and find a HDMI to VGA adapter. Takes a little bit because none of my stuff is organized (AT ALL) but I eventually find one. Need a keyboard too... off to the garage to dig through more boxes.

Eventually, I return, keyboard in hand. reboot the Pi again... lots of scrolling text, so far so good. I go to log in... hmm... crap. I seem to have forgotten my login and password.  Try a few things, no luck.

Eventually, a few Google searches reveal the default login and password which I hadn't changed, so now I'm logged in. do a quick ifconfig (the linux equivalent of ipconfig.exe) and it looks like I've got an IP address, but it's different than the one I bookmarked for OctoPrint. Ok that feels like progress.

Back to the desktop, change the ip address.  still no luck. Think... what's different?  New router. There's no way it's connecting, and the old IP was hardcoded.

So back to the Raspberry Pi. Shut it down, pull out the SD card so I can edit the network config file on my PC. Dig around in more boxes for an adapter. 

Uhoh... my main PC doesn't have a slot to read it. hmm... ok, looks like one of my other machines does, so I pop it in. Open the folder. It closes. *sigh* repeat this a couple times.  Apparently this adapter isnt any good.

Find ANOTHER adapter, pop it in... try again. Folder stays open this time. ok good, open up the network config file and sure enough, the wifi info is wrong. change it to my new router, update the password, close it up. Stick the card back in the pi, boot it up… wait, wait… log in.  Try hitting it from my desktop. no luck.

hmmm… think think, I sorta recall something about the server needing to be on the subnet as whatever machine is hitting it, maybe?  Check the ip on my desktop… ok, different subnet. Raspberry Pi is on wifi, desktop is wired. try changing the ip address on the pi, go through all the steps again… pull out card, put in card, edit file, etc…  back in the pi, boot it up… try to hit it.  Nope.

I have two wifi networks (don’t ask) so I try connecting to the other one. just for grins I do a sudo apt-get update command on the pi. lots of errors and timeouts. Hmm… ok this thing OBVIOUSLY isnt actually connecting to the internet. That’s weird.  Go back and change it again, back to the original network. try running the update command again… same errors. Ok, what’s going on?

Take a break, grab a drink… walk around the house mumbling profanities under my breath… go back upstairs, and look at my network info on my main pc. hmm… Linux is case sensitive.  ok, take another look, sure enough… SSID is all caps, but not in the network config file. Feeling a bit stupid, and triumphant, all at the same time, I change it again… boot it up.

Holding my breath, I try to hit the server from my PC. Success!! Awesome…  but apparently I’m about 6 versions behind. Ok ok, fair enough. hit the update button, go look for something to eat downstairs. come back, reboot again.

ok, it says my printer is not connected to the server. click the connect button… wait… wait… nothing. I check the log tab… it’s trying, but can’t find the printer. weird. *sigh* ok, check the cables. Yes, it’s connected via USB to the Pi. Hmm… why isn’t the light on?  Oh, it’s not plugged in. Duh.  Plug in the printer, light comes on, reboot the pi, again.

so far so good, press the connect button… check the log entries, trying to find the right baud rate… hmm… fail. again.

maybe it’s the usb cable. go find another one. dig around in boxes. I should really organize this stuff better.  Eventually find another cable that matches, swap it out. Try to connect, still no luck. I hardcode the speed and port info, reboot, try again. Nothing.

All I wanted to do was just fire off a simple test print. *sigh*

Start checking versions. OctoPrint uses a few plugins, including one to make it work with the M3D Printer. Looks like that’s pretty far out of date too. Ok hit the update button. Says everything is up to date. Nope. Don’t see any way to force an upgrade, so… Uninstall the plug in, get the newest version, reinstall… All of this I can do remotely from my PC, so that’s nice.  Try to connect… still nothing.  What. The. Hell?!?

Need coffee… we’re out of instant. ok, MAKE coffee… wait…

Come back, un-hardcode the connection info, set it back to auto, reboot again. *sip*  OctoPrint pops up, detects the printer!!  Awesome, now we’re in business. Where did I put that filament?  I know it’s around here somewhere. Eventually find another box with my most recent filament order. Wait… should probably recalibrate the printer first.

Ok, recalibrating is fairly easy… takes about 30 minutes.  Mostly automatic, with some minor manual adjustments.  Ok, time to load the filament.  There’s a button for that too (I love this setup) so I warm the printer up, guide in some filament… ok I think it’s in. Tell the server I’m ready. 

Find a file to print, upload it, slice it. send it to print.

Buzz… whirr… click click… humm…  so far so good.  wait a couple minutes, *sip*

Go take a look at the print bed… there’s nothing on it. *sigh*  ok, cancel the print, redo the filament loading process again.

fire up the model again, send it to print.  wait… *sip*

Ok, now it’s working… I see filament on the print bed. Now to wait 7 hours for the completed print.  Come back an hour later, there’s filament EVERYWHERE EXCEPT THE PRINT BED…  Cancel the print job, clean up the mess. Take out the print bed. Clean it really well. Put it back in.

Start the job for the 3rd time. Go downstairs, eat dinner, help my youngest son level up his Pathfinder character.

Come back an hour later, looking good… still printing. Go to bed.

I love my printer, and I love OctoPrint, and I’m fairly fond of the Raspberry Pi, but man, some days.

          3. MonoGame - Project Types Explained      Cache   Translate Page   Web Page Cache   

Originally posted on: http://blog.loethen.net/cwilliams/archive/2017/02/06/232983.aspx

MonoGame Project Types Explained

In this post, I’ll cover the various types of MonoGame projects you can create within Visual Studio.

image

Assuming you’re running MonoGame 3.5.1 (from the installer) your New Project dialog should look something like the picture above. If you’re pulling down more recent (i.e. unreleased) builds, then you’ll likely notice some differences, such as OUYA being removed, and new projects possibly being added.

MonoGame Windows Project

This first project type is the one I’ll be using in the next few sections. This is the standard Windows game project.

MonoGame Windows 10 Universal Project

This project type allows you to create games for one or more device families, such as Desktop, Mobile, IoT, Xbox, HoloLens. For more information about Universal Projects and Device Families, be sure to read this post.

MonoGame Android Project

If you want to create games for Android smartphones and tablets, using C#, this is the project for you.

MonoGame Content Pipeline Extension Project

I’ll go into a lot more detail on the content pipeline in a later section, but essentially this project type enables you to create your own content types, or modify how existing ones are processed for your games.

MonoGame OUYA Project

Remember the OUYA? Yeah, me either. Unfortunately, this little Android powered console didn’t survive, and this project type didn’t either.

MonoGame Cross Platform Desktop Project

This project allows you to create games for Linux and Mac, and WIndows of course. More on this later too.

MonoGame iOS Project

Want to make iPhone and iPad games? Well, you’re going to need a Mac to deploy them, but you can start coding them thanks to this project.

Next up…

I’ll cover what you get in the MonoGame Windows Project, and take a look at what all the various sections mean. If you came directly to this page, you can find the complete list of articles here.

          Firmware upgrade for Cisco branded Intel X710-DA4 adapter      Cache   Translate Page   Web Page Cache   

Hi all,

 

I am trying to make out Cisco branded Intel X710-DA4 quad port 10GBASE SFP+ network adapter to support 1G SFP modules. According to Intel documentation it should by supported starting with 6.01 NVM. The adapter currently has 5.05. I have compiled and installed the newest Intel Linux driver 2.4.10 and I have tried to use nvmupdate64e to upgrade NVM from 5.05 to 6.01. But it fails:

Intel(R) Ethernet NVM Update Tool

NVMUpdate version 1.30.22.3

Copyright (C) 2013 - 2017 Intel Corporation.

...

02) Cisco(R) Ethernet Converged NIC X710-DA4  5.05  1572 00:094 Update not available

Tool execution completed with the following status: Device not found

Press any key to exit.

The problem seems to be a Cisco specific NVM version not mentioned in nvmupdate.cfg.

 

ethtool -i output is:

driver: i40e

version: 2.4.10

firmware-version: 5.05 0x80002b50 0.385.8

expansion-rom-version:

bus-info: 0000:5e:00.0

supports-statistics: yes

supports-test: yes

supports-eeprom-access: yes

supports-register-dump: yes

supports-priv-flags: yes

 

Is it possible to use one of the NVM image files included with Intel's nmvupdate with this card or not? I have also checked Cisco's firmware files, but their newest version is the one we currently have in the card (and which does not support 1G SFPs, only 10G and special 10G/1G dual speed ones).

          How to install Linux Mint on your Mac or Windows machine      Cache   Translate Page   Web Page Cache   

I've started dabbling in the Linux operating system, for two reasons -- the Raspberry Pi (a $30 single board computer that runs on Linux) and losing the PIN code for my Bitcoin hardware wallet (which I recovered using an old MacBook Air running Linux).

If you are interested in Linux but don't know where to start, Lifewire has a good tutorial on how to install Linux Mint (one of the many different free distributions) on your Mac or Windows machine without overwriting the existing OS. That way, you can boot into either OS. It also shows you how to install Linux Mint onto a USB thumb drive and boot from that. Another recommendation: the book Linux for Makers, which is a great intro to the operating system, especially for Pi users.

          「最美应用」Chrome 专题:使用 Chrome,这些插件你不能错过      Cache   Translate Page   Web Page Cache   

Chrome 是一款支持多平台、由 Google 推出的浏览器,除了优秀的体验、简洁的界面,吸引不少用户使用的另一个关键就是可以安装大量插件,来获得更多的功能支持。

我们今天就为你整理了一些插件,可以帮助你美化 Chrome 或是提高效率。

Earth View from Google Earth

这是一款由 Google 推出的插件,它将为你每次新打开的选项卡设置一张卫星图像作为背景。而除了可以美化新选项卡,你还可以在历史记录里查看最近十张背景,分享或者下载你喜欢的卫星图像。

Momentum

Momentum 和 Earth View 类似,也将随机使用图库中精选过的图片来美化你的选项卡。除此之外,还提供了时钟、美文推送、提醒事项等工具,把你的新选项卡变成一个多功能启动器。

Adblock Plus

Adblock 是一款用来屏蔽广告的插件,可以给你一个清爽的网上冲浪体验。且不仅于此,除了广告,你还可以自定义屏蔽的内容,从网站插图到栏目,你所看见的每一个部分都可以被屏蔽。

同时因为是一个开源项目,你随时都可以自定义添加大家贡献的新过滤规则。

Tampermonkey

Tampermonkey 是多平台油猴管理器之一,你可以通过装入不同的脚本来实现不同的功能。例如去除视频前的广告、取消百度云等下载速度的限制、定制各类网页( 使用 Stylus 插件安装模板也可以定制美化网页)

你可以在 Greasy Fork、OpenUserJS 等网站寻找下载需要的脚本,安装后开启游猴,这些脚本将自动起效。

推荐一些有意思的脚本,Search By Image(支持多个站点的以图搜图)、购物党比价工具(可以在浏览商品时,查看对比多个购物网站的价格)、搜索引擎一键切换 soTab(在搜索时,可以快捷在多个搜索引擎之间切换)、為什麼你們就是不能加個空格呢?(自动在网页中所有的中文字和半形的英文、数字、符号之间插入空格)。

IE Tab

虽然我们总开玩笑「IE 浏览器,下载其他浏览器的最佳选择」,但很多时候总会遇到一些为 IE 挽业绩的「只支持 IE 内核的网站」。在使用了 IE Tab 后,我们可以在 Chrome 中打开 IE 内核浏览器才能打开的网页。

但是这款插件只在 Windows 版本的 Chrome 中起效,所以如果是 macOS、Linux 等其他系统的用户,很遗憾只能另寻他法了。

单词发现者+划词翻译

英文学习者不应该错过的一个组合。单词发现者可以将你浏览的网页中所有值得关注的英语词汇、惯用语和箴言谚语用设置的颜色高亮出来。帮助非母语英语学习者在浏览网页的时候发现新的表达方式。

而配合划词翻译类的插件则可以帮助学习者更加方便的查询高亮词汇的意思。两者搭配使用,会有很有意思的体验。

OneTab

装了插件后虽然用的很舒服,但是本就极吃内存的 Chrome 也变得更占内存更杀电量了。OneTab 可以帮你将所有闲置用不到的标签页都收纳起来,等需要访问时再选择恢复它们,不仅仅可以帮你把页面整理的非常干净,同时也将帮你节省大量内存。

Free Video Downloader

可以帮助你提取并下载网页中的视频,与之类似的插件还有 Video Downloader professional、Video DownloadHelper 和 Video Downloader GetThemAll,总有一个适合你的。

Remarkerbe

这款插件是专门为那些喜欢在阅读时做标记的人设计的,你可以在你喜欢的网页上划重点、做笔记。最后同步到你的印象笔记中。

书签侧边栏

这款插件可以帮助你管理你的书签,并且设计了一个全新的部件来代替原生的书签页。

你可以设置不同的方式来唤醒书签侧边栏,同时也可以自定义侧边栏的样式。除了更加美观的界面,同时也可以更加方便的管理你的书签,对他们进行自定义排序分组。

你可以在 Chrome Store 获得这些插件(需要一些魔法),如果无法浏览 Chrome store,请到「最美应用」微信公众号后台回复 「Chrome 插件」获取下载方式。

          「最美应用」坚果云:可能是国内体验最好的网盘      Cache   Translate Page   Web Page Cache   

「只改善效率,不改变习惯。」坚果云网盘的 slogan 这样写道,可能很多朋友不了解,甚至都没听说过这个已经拥有超过 500 万忠实用户的国产云盘。如果你们知道 Dropbox,那接下来我要介绍的就是「中国版 Dropbox」,相信你们会感兴趣的。

该有的全都有

一款专业的网盘,应该具备什么样的素质呢?

足够使用的空间、不限速的上传下载、便捷的操作流程、安全的登录和分享验证。

是的,刚才说的这些「坚果云」都有,7 年的沉淀,使得它现在就像一件被精心打磨过的艺术品,该有的都有,一分不多一分不少,几乎没有残缺。

哈,可能测评过程中的体验太优秀了,夸的有点多,不过这丝毫不影响坚果云的品质。

坚果云在 Windows、macOS、Android、iOS、Linux 以及 Windows Phone 平台下都有对应的版本,真正的全平台,不管你是什么系统,都可以用这款云盘随时随地的同步和访问指定的文件。

或许你已经开始想象坚果云的样子了,夸得这么秀,一定是款看起来就很有*格的应用才对啊,刚好,也要开始介绍它的基础功能了,我们一起来看一下。

看起来可能与你想象的有些不同,但是麻雀虽小,五脏俱全,界面非常简洁,没有任何复杂的元素,该有的功能也是一个都不少。

同步文件夹,最基础也是最能看出其用心程度的一个功能,市场上大多数带有同步功能的云盘都是只能同步单一的某个固定目录里的文件夹和文件,而坚果云不止于此,除了固定的坚果云目录,它做到了可以同步系统中的任何一个目录下的内容。

坚果云提供了两种同步的方式,一种是在客户端进行操作的,创建同步文件夹的功能,可以实现拖拽任一文件夹进行同步。

还有一种其实是更推荐大家使用的,不需要打开客户端,直接在文件夹上打开右键菜单,选择坚果云的同步选项即可,这样的设计也是想让用户忘掉客户端,沉浸在不知不觉的完美体验中。

时间轴功能,在坚果云同步过的文件夹中进行的任何一步操作都会被记录下来,不论是添加删除,还是修改文件名,甚至是修改过某文件中的内容,团队用户还可以记录对应的操作人,让你的每一次工作都有据可查。

你觉得这样就完了吗?当然没有,坚果云在时间轴功能上更进一步,造出了一台「时光机」。

在坚果云网页端对应的文件夹下,选择操作历史,可以看到用户在此进行的每一步操作,然后,重点来了,选中里面一个或几个步骤,点击撤销,文件就会回到该步骤之前的状态,真正做到了让每一步失误的操作都有后悔的余地。

不仅如此,坚果云还实现了「查看文件历史版本」的功能,对于许多文字工作者或者设计工作者来说,可能经常会遇到一个文档或设计稿在修改了数不清的版本后,发现还是之前的某个版本更好,此时又常常猛然发现,早已寻不到那个「完美」版的文件了。

这时候坚果云的强大作用就又得以体现,对于同步过的任何一个文件,在每次修改保存后,坚果云不仅会同步新版本的文件,同时旧版的文件一定也保存在了云端,在需要某个过去的版本时,选择下载即可。

看到这,是不是已经开始有一点理解我为何把坚果云比作艺术品了呢?

同样的,该功能也有两种操作方式,客户端拖拽以及选中文件右键菜单中查看,还是更推荐大家熟悉第二种操作,忘掉客户端的存在。

值得注意的部分,文件历史版本不会占用任何的云盘容量,同时这个保存还有时间限制。

1. 个人免费版用户能够保存一个月的历史版本;

2. 个人付费版用户能够保存三个月的历史版本;

3. 团队版用户至少能够保存六个月的历史版本;

4. 对于超过时间的历史版本,坚果云目前没有进行删除,但是保留随时从服务器上移除的权利。

文件分享,作为一款云盘,分享功能自然是必不可少的,熟悉的两种操作方式,坚果云在任何一个细节都考虑到了习惯客户端的用户,但是仍然坚持着想要让用户去使用,适应跳过客户端直接在系统右键菜单进行操作的方式。

内容的分享是以访问链接的形式,发送给其他用户,直接打开链接即可选择下载。

在网页端可以管理我的分享,将已分享内容取消,客户端以及网页端都可以对某一分享进行权限设置,包括针对用户、过期时间、访问密码以及上传下载权限。

使用云盘需要的基础功能坚果云都想到了,而且做的非常完善,高品质的应用理当如此,有一个好的需求分析和设计,并加以实现。

网盘/云盘/个人网盘

只改善效率,不改变习惯 

来说说坚果云的 slogan,这应该也是他们的设计理念,确实,他们做到了。在前面提到过,坚果云在尽力的满足用户习惯操作的同时,坚持的引导用户将坚果云看做系统自带的一个目录或者盘符,像复制粘贴一样去使用这个云盘。

在 macOS 中,坚果云作为用户中的一个目录依附于 Finder 中,不需要打开客户端,所有的文件操作在原本文件夹中进行即可,偶尔结合一下右键菜单,在使用上与系统目录几乎一致。

在 Windows 中,坚果云作为和 C 盘、D 盘等本地磁盘并列的一个盘符存在,除了不能安装软件,完全当成一个硬盘使用都可以,而且还能云同步。

在 Android 和 iOS 中,基础功能和大多网盘 APP 的操作类似,文件上传,下载同步,收藏等,多的是邮件抽屉,也是非常值得称赞的功能,在下一部分会进行介绍。

还有一点不同的是,iOS 端除了文件上传之外还支持照片的自动备份,相册中每添加一张照片即可同步到云端,与 iCloud 类似。

Linux 和 WP 端由于设备限制还没有办法进行测评,有需求的朋友可以自行体验。

相对来说,坚果云在电脑端的使用上还是要更为便捷,功能也更完善的。

「真正的科技就是让你感觉不到它的存在」,坚果云在一定程度上已经实现了目标。

做的更好

坚果云能成为国内口碑最好的云盘,除了已经介绍过的部分,还有一些特殊的功能做的非常好,不得不拿出来单独提一下啊。

微信邮件抽屉,坚果云中可以选择开启这个功能,它能够将微信文章直接已 PDF 的形式保存下来并同步到云端,遇到精彩的内容,也不需要再麻烦的截长图或者复制文字了。

增量同步,在坚果云中,同步文件如果被修改,可以在不破坏文件的前提下,直接保存文件修改的部分,不需要重新上传整个文件,即省事又高效。

增量同步支持的文件类型也非常的丰富,日常用到的用不到的文件格式坚果云都进行了支持。

第三方应用支持,坚果云作为国内唯一一个支持 WebDAV 的云服务,与 office 365 完美集成,可以在 office 软件中编辑文档,直接同步到云盘中,同时还支持许多精品应用如 Notability 等并与之无缝连接,方便用户同步数据。

安全性,坚果云非常重视安全问题,据官方提供,采用了网银级别的 SSL 数据传输加密和军方级别的 AES256 存储加密,虽然我也不懂,但是感觉很高大上的样子。

网盘/云盘/个人网盘

最美尾巴

本来是工作需要去体验坚果云的,结果坚果云成了我的工作需要。

从来没有想过,一款云盘能具有如此魅力。

当然,坚果云也不是真的十全十美的,前面所说足够使用的空间可能对于办公和日常用户来说是完全没问题的,但是如果你想用坚果云存小电影,那可能不太行。

坚果云能做到这样,与一直以来的坚持是分不开的,他们也曾和百度云等一众云盘巨头竞争,「有一段时间是比较慌的,」坚果云的创始人韩竹回忆说,「但这件事是两面性的,挤压的同时巨头也在替我们教育市场。」

希望坚果云能继续下去,不忘初心,今天开始我也是你们的忠实用户了。

          Running Windows 3.x -DOSBox Part 4      Cache   Translate Page   Web Page Cache   

Running Windows 3.x -DOSBox Part 4

Continuing on from theprevious tutorial, we have a working DOS installation running with DOSBox that we can install windows 3.11 on for running old 16-bit Windows software. Since a DOS installation is up and running correctly (unless, of course, it’s broken somehow), let’s begin by installing Windows 3.11 on to the disk image.

You shouldn’t have much trouble installing Windows 3.x onto the DOS image because it is, at the end of the day, a graphical user interface (GUI) for DOS. You can also run older versions of Windows (1.x and 2.x) using DOSBox, but you will need to use disk images (floppy or hard disk) to run an older version of DOS on DOSBox (version 2.x or 3.x for Windows 1.x, and version 3.30 or 4.x for Windows 2.x).

Preparing the Installer

You can specify each installation floppy in the configuration file (all 8 of them), and change them using Ctrl-F4 when prompted. The other option is to extract the contents of each image into a single directory to place in the hard drive image. Choosing the latter makes it easier to manage the floppy images that are not for Windows 3.x so that you don’t have to cycle through all of them just to get to what you want.

Installing Windows

Once you have everything required to set up Windows on DOSBox, run DOSBox so that it will boot from the C: image and allow you to run the installer. Once booted, invoke the Windows Setup program.

If using floppy images, run the executable on disk 1:

A:\setup

If installing from a directory with all of the files included:

C:\wininst\setup

Then go through the installation like you would on a DOS system, following the prompts, and choosing options.


Running Windows 3.x -DOSBox Part 4
Running Windows 3.x -DOSBox Part 4

If all went correctly, Windows 3.11 will have been successfully installed.

Configuration Running On Startup

Having Windows run on startup is entirely possible by simply inserting the “WIN” command on the last line of the autoexec script.


Running Windows 3.x -DOSBox Part 4
256-Colour Graphics

You should definitely take advantage of a higher resolution graphics displaying at least 256 colors compared to the horrid 16-color VGA graphics with a resolution of 640x480 pixels.

You will need to do the following:

Download the SVGA drivers: Place them in your hard disk image or on a separate floppy image. Ensure that your graphics device is set to the correct “svga_*” model in the machine variable under the “dosbox” section of the config file.

machine=svga_s3

On the web page provided, it will provide links to different drivers for different SVGA adapters. I chose the SVGA S3 graphics (svga_s3).

Once the drivers have been obtained and placed on a floppy image or the hard disk image, you will then need to run the setup executable that will allow you to configure the display settings in a DOS environment outside of Windows (C:\WINDOWS\SETUP.EXE). Navigate your way to the display settings using the up arrow key. Press enter to select it and bring up a list of possible drivers.


Running Windows 3.x -DOSBox Part 4

Find the option to select a driver from a different manufacturer and select it. Give it the location of the chosen SVGA driver (A:\ or otherwise) and it will show a list possible display modes. I’ve settled with a resolution of 800x600 pixels with support for 16.7 million colors.


Running Windows 3.x -DOSBox Part 4
Sound Blaster

Windows must be configured to use the Sound Blaster interface emulated by DOSBox before it will produce sound through it. It requires the IRQ and port numbers. Navigate to the Control Panel via the Main program group in the Program Manager, open up “Drivers”, click “Add”. Find version 1.0 of the sound blaster driver, and select it. After choosing it, you will be directed to find the port (sbbase in the config) and IRQ of the device. These are specified in the DOSBox configuration file under the “sblaster” section.

sbbase=220 irq=7

After choosing the correct values, you will be prompted to restart Windows. Once restarted, Windows will be able to interact with the emulated sound blaster device to play sounds through it.

Conclusion

In these guides, you have learned how to take great advantage of DOSBox and its features by creating and manipulating floppy images using tools provided by linux, creating and accessing a hard drive image for DOSBox, installed a real DOS version on said image, and now installing Windows 3.11 to run the ancient Windows software from the early 1990s. I would also imagine that you would have taken the liberty of running several old DOS games from the 80s and 90s using DOSBox (doesn’t have to be on a hard disk image, of course). Have fun!


          much faster curl uploads on Windows with a single tiny commit      Cache   Translate Page   Web Page Cache   

These days, operating system kernels provide TCP/IP stacks that can do really fast network transfers. It's not even unusual for ordinary people to have gigabit connections at home and of course we want our applications to be able take advantage of them.

I don't think many readers here will be surprised when I say that fulfilling this desire turns out much easier said than done in the windows world.

Autotuning?

Since Windows 7 / 2008R2, Windows implements send buffer autotuning . Simply put, the faster transfer and longer RTT the connection has, the larger the buffer it uses (up to a max) so that more un-acked data can be outstanding and thus enable the system to saturate even really fast links.

Turns out this useful feature isn't enabled when applications use non-blocking sockets. The send buffer isn't increased at all then.

Internally, curl is using non-blocking sockets and most of the code is platform agnostic so it wouldn't be practical to switch that off for a particular system. The code is pretty much independent of the target that will run it, and now with this latest find we have also started to understand why it doesn't always perform as well on Windows as on other operating systems: the upload buffer (SO_SNDBUF) is fixed size and simply too small to perform well in a lot of cases

Applications can still enlarge the buffer, if they're aware of this bottleneck, and get better performance without having to change libcurl, but I doubt a lot of them do. And really, libcurl should perform as good as it possibly can just by itself without any necessary tuning by the application authors.

Users testing this out

Daniel Jelinski brought a fix for this that repeatedly poll Windows during uploads to ask for a suitable send buffer size and then resizes it on the go if it deems a new size is better. In order to figure out that if this patch is indeed a good idea or if there's a downside for some, we went wide and called out for users to help us .

The results were amazing. With speedups up to almost 7 times faster , exactly those newer Windows versions that supposedly have autotuning can obviously benefit substantially from this patch. The median test still performed more than twice as fast uploads with the patch. Pretty amazing really. And beyond weird that this crazy thing should be required to get ordinary sockets to perform properly on an updated operating system in 2018.

Windows XP isn't affected at all by this fix, and we've seen tests running as VirtualBox guests in NAT-mode also not gain anything, but we believe that'sVirtualBox's "fault" rather than Windows or the patch.

Landing

The commit is merged into curl's master git branch and will be part of the pending curl 7.61.1 release, which is due to ship on September 5, 2018 . I think it can serve as an interesting case study to see how long time it takes untilWindows 10 users get their versions updated to this.

Table of test runs

The Windows versions, and the test times for the runs with the unmodified curl, the patched one, how much time the second run needed as a percentage of the first, a column with comments and last a comment showing the speedup multiple for that test.

Thank you everyone who helped us out by running these tests!

          LR-Link Launches New Mass-Market 10GigE NIC Based on Tehuti Networks’ Tech      Cache   Translate Page   Web Page Cache   

LR-Link, a maker of networking solutions from China, has announced its first 10 GbE NIC, the wordy-named LREC6860BT. The new NIC is the first such retail product we've seen based on a design from Tehuti Networks, an Israel-based developer, bringing some more welcome competition to the 10GigE NIC market. LR-Link will be aiming at the (relative) mass-market for standalone NICs with this card, with the card now selling in Japan as well as online for less than $100.

Under the hood, the LR-Link LREC6860BT NIC is based on Tehuti Networks’ TN4010 MAC, which is further paired with Marvell’s Alaska X 88X3310P 10 GbE transceiver. The card features a PCIe Gen 2 x4 interface as well as an RJ45 connector that supports 100M, 1G, 2.5G, 5G, and 10G speeds using Cat5e/Cat6/Cat6A cabling. The card fully supports contemporary operating systems from Apple, Microsoft, and VMware as well as various Linux distributives. Therefore, the NIC is drop-in compatible with most computers that are in use today.

Release Date Q3 2018
Additional Information Link

The LREC6860BT is currently available from at least one retailer in Japan for ¥10,164 ($91) with VAT, which is not very high considering the fact that PC components tend to cost more in Japan than in the rest of the world. Unfortunately products from LR-Link aren't readily available from retailers outside China and Japan, but the company’s devices (including the 10 GbE NIC) can still be purchased from official stores on AliExpress, Ebay, and JD.com.

10 GbE networks are not yet widespread in SOHO environments, primarily because there are not many reasonably-priced 10 GbE switches. Meanwhile, a number of companies have released their relatively affordable 10 GbE NICs based on chips from Aquantia over the past few quarters, anticipating demand for such cards from enthusiasts. Aquantia is not the only provider of solutions for inexpensive 10 GbE cards. Tehuti Networks is considerably less known because it is focused on working with enterprise OEMs rather than with AIBs and retail. Nonetheless, having a second player in the space for cheap 10GigE/NBASE-T silicon is an important part of driving down the cost of the technology  –and boosting adoption – even further.

          ADDM: review of some older CVE vulnerabilities      Cache   Translate Page   Web Page Cache   

This document contains official content from the BMC Software Knowledge Base. It is automatically updated when the knowledge article is modified.


PRODUCT:

BMC Discovery


COMPONENT:

BMC Atrium Discovery and Dependency Mapping


APPLIES TO:

BMC Atrium Discovery and Dependency Mapping



PROBLEM:

 

 A security tool reported some vulnerabilities for ADDM 9.0.

  

 

 


SOLUTION:

 

Here are some examples of vulnerabilities that were already reviewed:

  
    
  
  CVE-2004-2761
     
  Red Hat has addressed this issue in "Red Hat Certificate System 8#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000" released in RHEL 5.3+ 
  
          => false positive 
  
           
  
  CVE-2009-3555
     
          impacts the package java-1.6.0-openjdk that is not installed in the ADDM 9+ appliance 
  
          => false positive 
  
   
      
   
   CVE-2010-4478 
       
           "Not vulnerable. This issue did not affect the versions of openssh as shipped with Red Hat Enterprise Linux 4, 5, or 6."  
   
           => false positive  
  
  
    
  
  CVE-2010-4755
     
          "We do not consider a denial of service flaw in a client application such as sftp to be a security issue." 
  
          => false positive 
  
   
      
   
   CVE-2010-5107 
1/ Google CVE-2010-5107 and look for the RedHat portal, in this case:   
       https://access.redhat.com/security/cve/CVE-2010-5107   
  
2/ On this page, look for the RHSA number, in this case "RHSA-2013:1591". See :   
    https://rhn.redhat.com/errata/RHSA-2013-1591.html   
  
3/ On this page, look for the entry for "Red Hat Enterprise Linux Server (v. 6)" and scroll down to the section titled "x86_64:"   
  
4/ In this section, you will see a list of packages that include fixes for this RHSA. Not all of these will apply to ADDM. You can compare this list to the packages listed in https://docs.bmc.com/docs/display/ADDMOSU/Latest+RHEL+6+operating+system+upgrade. If it's not listed here, the package is not installed in ADDM.   
  
5/ In this case, the packages that match both the RedHat page and our doc are:   
openssh-5.3p1-94.el6   
openssh-clients-5.3p1-94.el6   
openssh-server-5.3p1-94.el6   
  
and we can see that the version numbers from our doc match those of the RedHat page; therefore the fix is included in the latest ADDM OS upgrade.   
  
So in summary, we have the RedHat fix, but all the vulnerability scanner can see is that it's not OpenSSH v6.2.  
   
      
  
  
    
  
  CVE-2011-5000
     
          extract"[...] low security impact. A future update may address this issue." 
  
          => The ADDM OS upgrade embeds the RHEL fix when it is available (RedHat has not provided any plans for now). 
  
    
  
  CVE-2012-0814
     
          extract: "Not vulnerable. This issue did not affect the versions of openssh as shipped with Red Hat Enterprise Linux 4, 5, or 6." 
  
          => false positive 
  
    
  
  CVE-2012-2733
  
          according to 
     
          the solution is upgrade to  tomcat6-6.0.35-29_patch_06.ep6.el6.noarch.rpm 
  
          ADDM 9.0 contains tw-tomcat-6.0.35-2.rhel6.noarch 
  
          ADDM 9.0SP1 contains tw-tomcat-6.0.36-1.rhel6.noarch 
  
          => upgrade to ADDM 9.0SP1 to resolve the issue 
  
    
  
  CVE-2012-3546
  
          according to 
     
          It impacts "Apache Tomcat 6.x before 6.0.36" 
  
          => upgrade to ADDM 9.0SP1 to resolve the issue 
  
    
  
  CVE-2012-4431
     
          "This issue did not affect [...] tomcat6 as shipped with Red Hat Enterprise Linux 6" 
  
          => false positive 
  
    
  
    
  
  CVE-2012-4534
     
          this impacts "Apache Tomcat 6.x before 6.0.36" 
  
          => upgrade to ADDM 9.0SP1 to resolve the issue 
  
    
  
  CVE-2012-5568
  
          the link below provides a workaround for this low impact problem: 
     
    
  
    
  
  CVE-2012-5885/CVE-2012-5886/CVE-2012-5887
  
          according to 
           
          This impact "Apache Tomcat [...] before 6.0.36," 
  
          => upgrade to ADDM 9.0SP1 to resolve the issue

          Github 上最火的 Google 图像下载工具使用说明:google-images-download      Cache   Translate Page   Web Page Cache   

批量下载图片这种事儿,不管是谁可能都要遇上那么几回。作为一名信息管理与信息系统讲师,我经常需要大量图像来训练模型,这个需求也就更强烈。

一般来说,搜图时我们都会在 Google 图片中搜索我们想要的东西。比如键入「Walle」,就能搜到皮克斯制作的动画《瓦力》的主人公:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

搜索的结果,合乎我们的要求。Google 不但给了咱们图片,而且标记也已经做好了,下一步只要批量下载就行了。

可就是在批量下载这一步,很多人犯了难。和各位一样,我第一个想法也是看看有没有什么现成的 Chrome 插件能批量存图,结果却发现并没有一款从准确度和操作上都足够理想的工具。

山重水复的时候,我发现了一个特别棒的 Github 项目,叫做 google-images-download

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

项目发布至今,只有短短 5 个月的时间,星标数量已经上了 2000,看来确实非常受欢迎。

google-images-download 是个 Python 脚本。但**使用它却不需要什么代码知识——一条命令,就完成 Google 图片搜索和批量下载功能。而且,这工具还跨平台运行,Linux, Windows 和 macOS 都支持。简直是懒人福音。

安装

google-images-download 安装很简单。以 macOS 为例,只需要在终端下,执行以下命令:

pip install google_images_download

安装就算完成了。当然,这需要你系统里已经安装了 Python 环境。如果你还没有安装,或者对终端操作命令不太熟悉,可以参考我的《如何安装 Python 运行环境 Anaconda?(视频教程)》一文,学习如何下载安装 Anaconda ,和进行终端命令行操作。

运行

这次我们尝试下载什么图片呢?想起《我不是药神》里面有个叫谭卓的女演员,演的不错。可是我一开始,把她当成郝蕾了。咱们就尝试下载一些谭卓的图片吧。

电影《我不是药神》海报
电影《我不是药神》海报

首先,我们先指定图片要下载的位置,我把它指定到了「下载(Download)」这个文件夹:

cd ~/Downloads

然后,在终端里执行即可:

googleimagesdownload -k "谭卓" -l 20

这行代码中:

  • googleimagesdownload 是命令名,告诉系统我们现在要执行什么命令,现在我们要执行的就是「googleimagesdownload」这个命令。
  • -k 指的是「关键词(Keyword)」,所以它的后面紧跟着关键词,在这里是 "谭卓",注意关键词要用半角直双引号框起来。
  • -l 指的是「限定(limit)」,指定下载图片的数量。本例中,我们下载了 20 张。

下面是执行过程:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

最后的 Error: 1 说明, 下载过程中,发生了一个错误。但程序依然正常地将下载流程运行完毕。我们来看结果:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

我们发现,下载的图片已经都存放在 ~/Downloads/downloads/谭卓 下面。google-images-download 非常贴心地,为我们建立子目录。

基本上,这一行命令就能帮我们解决正常情况下,批量下载图片的需求了。

进阶

然而,在有的情况下,我们需要下载的图片远远大于 20 张。比如说我看了半天照片,还是分不大清楚郝蕾和谭卓。那么为了彻底分清两位女演员,我打算再下载 200 张郝蕾的照片试试。

仿照刚才的命令,执行:

googleimagesdownload -k "郝蕾" -l 200

然后,你会发现报错了:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

遇到问题,不要慌。你得认真看看错误提示。注意其中出现了一个关键词:chromedriver。这是个什么东西呢?

我们回到 google-images-downloadgithub 页面,以 chromedriver 为关键词进行检索。你会立即找到如下结果:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

原来,当我们下载的图片数量超过 100 张时,程序就必须调用 Seleniumchromedriver 才行。不知道它俩是啥无所谓,要了咱装就行了。

Selenium 在我们安装 google-images-download 的时候,就已经同时安装好了。现在我们只需要下载 chromedriver 即可,它的下载链接在 这里

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

下载时请注意根据自己的系统类型选择合适的版本:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

我这里选的是 macOS 版本。下载后,压缩包里面只有一个文件,把它解压,然后放在 ~/Downloads 目录下。

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

接下来我们就可以批量下载超过 100 张图片了。执行以下命令:

googleimagesdownload -k "郝蕾" -l 200 --chromedriver="./chromedriver"

我们会发现多了一个 参数 --chromedriver。它是用来告诉 google-images-download 解压后 chromedriver 的所在路径。这回机器勤勤恳恳,帮我们下载郝蕾的照片了:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

下载完毕后发现也有一些报错,部分图片没有正确下载。但这对总体结果没有太大影响。为了保险起见,建议你设置下载数量时,多设置一些。给自己留出安全边际嘛。

最后我们再打开下载后的目录 ~/Downloads/downloads/郝蕾 看看:

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

这回,你能分清楚她俩不?

更多参数介绍

评分这么高的 google-images-download ,自然不可能只有上例中这两三个参数选项。如果你对它感兴趣,可以用 这个链接查看全部可用参数列表。

null#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

我数了一下,一共有39项。篇幅所限,这里就不一一展开罗列了。但是其中几个特色参数,我还是希望提示你一下,因为你在实际工作中,很可能会觉得它们有用处。

  • --format: 选择图片格式,例如 jpg, png, gifsvg 等;
  • --usage_rights:选择图片版权,例如 labeled-for-nocommercial-reuse 等。如果你希望建立自己发布内容用的图片素材库,可以用这个选项,避免踩到版权的坑上,被人家狮子大开口要钱;
  • --size:选择图片大小。假如说你对于图片分辨率有要求,可以用 >10MP ,只下载像素数量超过 10M 的那些图片;
  • --type:选择图片类型。例如只想要照片,可以用 photo ,只想要动漫形象,可以用 animated
  • --time:选择图片被检索的时间。假如想要过去一周的图片,可以使用 past-7-days
  • --specific_site:指定图片存储网站。可以将搜索结果,限定在某个网站域名范围内;

最后还有一个参数,是 ---safe_search,它的作用是启用安全搜索,来保证搜索结果中,不会出现不利于精神文明建设的内容。

As a contractor and a member of our team at AppSwitch (FKA Fermat), Tycho Andersen helped implement a fully user space version of system call trap mechanism based on seccomp / fd-passing and participated in our team discussions about upstreaming a kernel version of the feature. Given that context, we were taken aback that he posted the v1 patch set without letting us know and without any mention of AppSwitch in the post even though he was still under contract at that time.

In any case, please note that we will communicate with Tycho directly regarding this matter going forward.

iChemLabs Products 2016.1 | 899.6 mb

iChemLabs, the developer of the popular ChemDoodle chemical drawing program, and Royal Society of Chemistry's ChemSpider, a leading provider of chemical services and data on the internet, has released new versions of ChemDoodle and ChemDoodle 3D is a scientific visualization platform with a focus on user customizability and universal support.
ChemDoodle 8.0.1
[/center]

[center]
If you are looking for a chemical sketcher or an alternative to your current chemical drawing application, there is no better choice than ChemDoodle. ChemDoodle works on all operating systems (both 32 and 64 bit), has one of the largest feature sets in the industry, has the most customizable graphics, pastes scalable vector graphics and provides round trip editing into Microsoft Office, iWork and OpenOffice (among others), and can read and write all of our competitors' formats. This is in addition to our web and mobile ChemDoodle extensions!

New features in ChemDoodle 8.0.1:

- The graphics system has been improved even beyond current industry standards for graphics. Every bond merge and pixel was scrutinized. Chemical structures have never looked better. ChemDoodle provides the best graphics in chemistry, everything else is a waste of money.
- Major IUPAC naming improvements, including very advanced ring systems.
- Full support for Retina display Macs and support for high-DPI Windows hardware.
- A new query structure system for defining sets of molecules and for searching partner services.
- New powerful tools for drawing arbitrary rings and crown ethers to atoms and bonds.
- Superscript and subscript merging to easily create atomic notations and other chemical text.
- More specific cleaning tool for adjusting only a selection of a structure.
- Text output options and improvements for EPS and SVG files in addition to PDF.
- A dramatically improved Templates widget with new and more aesthetic templates.
- Read in NTUPLES (multiple spectra) from JCAMP files.
- Added support for both the SketchEl (el) and Crystallographic Information Format (cif) filetypes.
- More support for working with the ChemDoodle Web Components.
- Dozens of new BioArt graphics.
- Performance improvements for faster work.
- Dozens more new features: two new bond types, implicit hydrogen control, automatic IUPAC locant labelling, vastly improved condensed labels, search files based on query structures, recursive SMARTS, metric support for document aids and rulers, a new precise form for scaling a specific bond, many interface improvements and so much more.

ChemDoodle 3D version 2.0.1

ChemDoodle 3D is a scientific visualization platform with a focus on user customizability and universal support. Just like its 2D counterpart, all of the graphics are fully customizable and controllable. The large feature set is well organized for intuitive access and we develop ChemDoodle 3D to work with the vast majority of graphics cards in use. So no need to worry about long installation procedures or having to purchase specific hardware. You will not be disappointed with how easy it is to get started and produce results with ChemDoodle 3D!

New features in ChemDoodle 3D version 2.0.1:

- Full Retina display support on Mac OS X.
- Support for high DPI Windows hardware.
- The visual specifications of the scene can now be applied to selected content, or individual objects, as opposed to the entire scene. Right-click on objects and select the Format... menu item to show visual options for that object. New representation quick buttons are now available for modifying residue atoms and bonds, ribbon models and nucleic acid models in addition to non-residue atoms and bonds.
- Protein and nucleic acid information can now be loaded from PDB files. Ribbon, trace and tube models can be generated for proteins. Ladder models can be generated for nucleic acids. The models are fully customizable. Control dimensions, alpha helix widths, coloring and more. Both B-spline and Catmull-Rom splines can be used to generate models. Water can be displayed as stars. Residue atoms can be controlled separately from hetatoms. Load PDB files by PDB id.
- Periodic data can now be loaded from CIF files. Unit cells of any geometry are resolved. Functions for periodic systems will be provided in the Periodic menu. Build supercells.
- An advanced selection system has been implemented. Select, deselect and reselect content. Select all, next molecule, inverse and by SMARTS. Use the new selection mode to select content or use the selection window to list the contents of the scene and select the content you wish to work with. The selection window is very advanced and will show you what you are currently hovering.
- Fogging can now be defined in scenes using linear, exp1 or exp2 algorithms. Fog color can be defined as well as fog ranges.
- A compass can be added on the bottom left of the scene or through the camera's origin.
- 3D scenes can now be printed.
- Added quick quality options in the View menu to quickly switch between a range of higher and lower quality rendering settings to allow you to improve graphics or performance.
- Image export now allows for transparent backgrounds in capable image types. This allows you to easily use ChemDoodle 3D generated graphics in various media with custom backgrounds.
- Many new smaller features: added an option to remove shadows from text, added projection menu items, certified the correct 3D stereochemistry is generated from 2D drawings, picking can now handle any number of objects, and more.
- Updated to support ChemDoodle Web Components v7. Shapes can now be read/written using ChemDoodle JSON.
- Your iChemLabs account can now be accessed from ChemDoodle 3D. ChemDoodle 3D customers receive a free account for accessing ChemDoodle Mobile. If you also have ChemDoodle desktop, this is the same account.
- Dozens more improvements and additions.

          「最美应用」Chrome 专题:使用 Chrome,这些插件你不能错过      Cache   Translate Page   Web Page Cache   

Chrome 是一款支持多平台、由 Google 推出的浏览器,除了优秀的体验、简洁的界面,吸引不少用户使用的另一个关键就是可以安装大量插件,来获得更多的功能支持。

我们今天就为你整理了一些插件,可以帮助你美化 Chrome 或是提高效率。

Earth View from Google Earth

这是一款由 Google 推出的插件,它将为你每次新打开的选项卡设置一张卫星图像作为背景。而除了可以美化新选项卡,你还可以在历史记录里查看最近十张背景,分享或者下载你喜欢的卫星图像。

Momentum

Momentum 和 Earth View 类似,也将随机使用图库中精选过的图片来美化你的选项卡。除此之外,还提供了时钟、美文推送、提醒事项等工具,把你的新选项卡变成一个多功能启动器。

Adblock Plus

Adblock 是一款用来屏蔽广告的插件,可以给你一个清爽的网上冲浪体验。且不仅于此,除了广告,你还可以自定义屏蔽的内容,从网站插图到栏目,你所看见的每一个部分都可以被屏蔽。

同时因为是一个开源项目,你随时都可以自定义添加大家贡献的新过滤规则。

Tampermonkey

Tampermonkey 是多平台油猴管理器之一,你可以通过装入不同的脚本来实现不同的功能。例如去除视频前的广告、取消百度云等下载速度的限制、定制各类网页( 使用 Stylus 插件安装模板也可以定制美化网页)

你可以在 Greasy Fork、OpenUserJS 等网站寻找下载需要的脚本,安装后开启游猴,这些脚本将自动起效。

推荐一些有意思的脚本,Search By Image(支持多个站点的以图搜图)、购物党比价工具(可以在浏览商品时,查看对比多个购物网站的价格)、搜索引擎一键切换 soTab(在搜索时,可以快捷在多个搜索引擎之间切换)、為什麼你們就是不能加個空格呢?(自动在网页中所有的中文字和半形的英文、数字、符号之间插入空格)。

IE Tab

虽然我们总开玩笑「IE 浏览器,下载其他浏览器的最佳选择」,但很多时候总会遇到一些为 IE 挽业绩的「只支持 IE 内核的网站」。在使用了 IE Tab 后,我们可以在 Chrome 中打开 IE 内核浏览器才能打开的网页。

但是这款插件只在 Windows 版本的 Chrome 中起效,所以如果是 macOS、Linux 等其他系统的用户,很遗憾只能另寻他法了。

单词发现者+划词翻译

英文学习者不应该错过的一个组合。单词发现者可以将你浏览的网页中所有值得关注的英语词汇、惯用语和箴言谚语用设置的颜色高亮出来。帮助非母语英语学习者在浏览网页的时候发现新的表达方式。

而配合划词翻译类的插件则可以帮助学习者更加方便的查询高亮词汇的意思。两者搭配使用,会有很有意思的体验。

OneTab

装了插件后虽然用的很舒服,但是本就极吃内存的 Chrome 也变得更占内存更杀电量了。OneTab 可以帮你将所有闲置用不到的标签页都收纳起来,等需要访问时再选择恢复它们,不仅仅可以帮你把页面整理的非常干净,同时也将帮你节省大量内存。

Free Video Downloader

可以帮助你提取并下载网页中的视频,与之类似的插件还有 Video Downloader professional、Video DownloadHelper 和 Video Downloader GetThemAll,总有一个适合你的。

Remarkerbe

这款插件是专门为那些喜欢在阅读时做标记的人设计的,你可以在你喜欢的网页上划重点、做笔记。最后同步到你的印象笔记中。

书签侧边栏

这款插件可以帮助你管理你的书签,并且设计了一个全新的部件来代替原生的书签页。

你可以设置不同的方式来唤醒书签侧边栏,同时也可以自定义侧边栏的样式。除了更加美观的界面,同时也可以更加方便的管理你的书签,对他们进行自定义排序分组。

你可以在 Chrome Store 获得这些插件(需要一些魔法),如果无法浏览 Chrome store,请到「最美应用」微信公众号后台回复 「Chrome 插件」获取下载方式。

          Crontab does not work from every gem      Cache   Translate Page   Web Page Cache   

My linux server is running a Rails 4 app with Nginx/unicorn.

I am using the Whenever gem to schedule tasks. Everything was working normally until a couple of days ago when the cron jobs appear to have simply stopped running.

This is in my schedule.rb file:

every 5.minutes do runner "Video.send_to_wistia", environment: 'production' end

This is what I see when I run crontab -l :

# Begin Whenever generated tasks for: myapp 0,5,10,15,20,25,30,35,40,45,50,55 * * * * /bin/bash -l -c 'cd /home/myuser/myapp && bin/rails runner -e production '\''Video.send_to_wistia'\''' # End Whenever generated tasks for: myapp

I have restarted unicorn. I also made sure to run:

whenever --update-crontab myapp

In my video.rb file, which contains the action that should run, I placed some log code:

def self.send_to_wistia logger.debug( "Sending videos to wistia at #{Time.now}" ) ...

I've been watching the logs and nothing appears there.

PS: My first instinct was that maybe the site is running in development mode (which the whenever task is not configured to run in) but this does not seem to be the case, because I see now records going into my production database.

Update:As the user for my app, when I run service cron status I get this: cron: unrecognized service . But I'm not sure if this is checking the user's crontab or the system-wide.

Update2:This is what I see when I run pgrep -l cron :

Update 4:I ran /bin/bash -l -c 'cd /home/clippo/clippo2 && bin/rails runner -e production '\''Video.send_to_wistia'\''' and this is what I see:

/home/myuser/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/railties-4.0.0/lib/rails/commands/runner.rb:53:in `eval': No such file or directory - /home/myuser/myapp/tmp/video_uploads/190 (Errno::ENOENT) from /home/myuser/myapp/app/models/video.rb:31:in `new'

This error message is really confusing because that directory DOES exist and always has.

Does your

crontab -l

output match what you have in your schedule file for your whenever gem?

I usually do

whenever -w

any time I make changes to my schedule file and want my crontab updated.

Although it seems like you're having issues getting your actual rb file to run that logger command. you could try editing your schedule.rb to have a set :output like this ->

set :output, "/Users/home/rubylogs/vendorcatalog.log" every :day, :at => "2:31am" do command "cd /Users/home/automation/Vendor\ Catalog; parallel_test -n 1 *.rb" end

The parallel test stuff isn't really relevant but you get the point. See if you get any output when you do it that way? That should tell you whether or not it's running something.

How Do You Start In The Tech Sector?
Career

August 9th, 2018

The tech sector, if you know what you're doing, is easier than most fields to get started in. However, you do have to know what you're doing. In this post, I'm going to step through a series of ways to get started, in case you're not sure.

Sounds easy, right? Well, nothing worthwhile's easy. Now, to be fair, I don't mean " if you know what you're doing " in any patronising or condescending way.

What I mean is that, unlike say being a GP , dentist , civil engineer , corporate lawyer , Queen's Council (QC) , etc., you don't need to have years of formal training.

What’s more, you don’t need to be registered with an industry group/board before you're allowed to work. These can include the Institute of Chartered Accountants , the Queensland Law Society , or the Queensland Bar Association .

In IT, however, most people whom I've spoken to over the years care far more for what you can do, rather than what a piece of paper says you could do.

Let's Say You Want to Write Code
How Do You Start In The Tech Sector?

If you want to write code, then start by learning the basics of a software development language. I'm not going to get into a flame war about one language or another, whether one's better than another or not.

That's for people with too much time on their hands, and for people who are too emotionally invested in their language(s) of choice ― or dare I say, just a bit insecure.

There are a host of languages to choose from, readily available on the three major operating systems ( linux , macOS , and windows ). Some of the most common, where you'll find the most amount of help and documentation, are php , Perl , C/C++ , Java , Go , Ruby , python , Haskell , and Lisp . Grab yourself and editor, or an IDE, learn it inside out, and get started learning to write code.

I've linked to a host of excellent online resources for each at the end of the article.

For my part, I prefer any language borne out of C/C++. I've written code in Visual Basic and Cobol and didn't come away from either experience positively.

Once you've learned the basics, start contributing to an open source project! You don't need to be overly ambitious, so the project doesn't need to be a big one.

It could be a small library, such as VIM for Technical Writers that I maintain every so often. It could, however, be the Linux Kernel too, if that's your motivation and you are feeling particularly ambitious.

Regardless of what you choose, by contributing to these projects you'll learn far faster and better than you likely could in any other way. Why?

Because you're working on real projects and have the opportunity to be mentored by people who have years of hands-on experience. You'll get practical, guided experience, the kind you'd likely take years to acquire on your own.

They'll help teach you good habits, best practices, patterns, techniques, and so much more; things you'd likely take ages to hear about, let alone learn.

What's more, you'll become part of a living, breathing community where ― hopefully ― you're encouraged to grow and appreciate the responsibilities and requirements of what it takes to ship software.

But I'd Rather Be a Systems Administrator?
How Do You Start In The Tech Sector?

The same approach can be broadly applied. Here’s my suggestion. Install a copy of Linux , BSD , or Microsoft Windows on an old PC or laptop. As you're installing it, have a look around at the tools that are available for it

hint:open source provides a staggering amount of choice. #justsayin .

Get to know how it's administered, whether via GUI tools (and the Power Shell) on Windows, or via the various daemons and their configuration files and command-line tools on Linux and BSD.

Server administration's a pretty broad topic, so it's hard ― if not downright impossible ― to suggest a specific set of tools to learn. I'm encouraging you at this point to get a broad understanding.

Later, if you're keen, you can specialise in a particular area. However, for now, get a broad understanding of:

Networking User and Group Management Installation Options and Tooling Service/Daemon configuration; and Disk Management.

Whether you're on Linux, BSD, or Windows, I've linked to a host of resources at the bottom of the article to help get you started.

Now that you've learned the fundamentals do something where people can critique you and hold you accountable, such as hosting a website of your own, through a provider such as Digital Ocean , or Linode .

The web server you use, whether Apache , NGINX , Lighttpd , or IIS doesn't matter. Just use one that works well on your OS of choice.

Once you've got it up and running, start building on the day to day tasks required to keep it up and running nicely. Once you've grown some confidence, move on to learning how to improve the site's security and performance, and deployment process.

This can include:

Optimising the web server, filesystem, and operating system configuration setting for maximum throughput Setting up an intrusion detection system (IDS); and Dockerising your site To Go Open Source or Microsoft?

By now you've got a pretty good set of knowledge. However, stop for just a moment, because it's time to figure out if you're going to specialise in open source (Linux/UNIX/BSD) or whether you're going to focus around Microsoft's tools and technologies.

You can become knowledgeable in both, and most developers and systems administrators that I know do have a broad range of knowledge in both. However, I'd suggest that it's easier to build your knowledge in one rather than attempting to learn both.

Depending on the operating system you've been using up until now, it's likely that you've already made your choice. However, it's good to stop and deliberately think about it.

What Do You Do Next?

Now, let's get back to building your skills. What do you do next? If you want to be a sys admin, start look around for opportunities to help others with their hosting needs.

Don't go all in ― yet . There's no need to rush. Keep stepping up gradually , building your confidence and skills.

If you're not sure of who might need help, have a think about:

What clubs are you involved in? Do you have friends with small businesses that might need support? Do you know others who want to learn what you have and need a mentor? I'm sure that as you start thinking, you'll be able to uncover other ideas and possibilities. Now you have to get out of your comfort zone, contact people and ask them if they need help.

Worst case scenario, they say no. Whatever! Keep going until you find someone who does want help and is willing to take you on.

Regardless of the path that you take, you should feel pretty confident in your foundational skills, because they're based on practical experience.

So, it's time to push further. To do that, I'd suggest contacting a University, a bank, or an insurance provider, if you want to cut your teeth on big installations.

Sure, many other places have big server installations. However, these three are the first that come to mind.

If you are focused on software development, here are a few suggestions:

Contact software development companies (avoid " digital agencies ") and see if they’re hiring. Talk to your local chamber of commerce and industry and let them know you’re around and what you do. Find the local business networking groups and go to the networking breakfasts. Get involved in your local user groups (this goes for sys admins too, btw). Start a user group if there isn’t one for what you want to focus on. In Conclusion

I could go on and on. The key takeaway I'm trying to leave you with is that, if you have practical experience , you'll increase the likelihood of gaining employment.

Any employer I've had of any worth values hands-on experience over a piece of paper any day.

Don't get me wrong; there's nothing wrong with degrees or industry certifications. And for complete transparency:

I have a Bachelor of Information Technology I'm LPIC-1 certified; and I’m a Zend (PHP 5) Engineer

However, university qualifications and industry certifications should only reinforce what you already know, and not be something that is used to get your start.

With all that said, I want to encourage you to go down the Open Source path, not Microsoft. But I’m biased, as I’ve been using Linux since 1999.

Regardless, have a chew on all that, and let me know what you think in the comments. I hope that, if you’re keen to get into IT, that this helps you do so, and clears up one or more questions and doubts that you may have.

Everyone has their own favourite way to take notes in Kali. For me it involves copy-pasting lots of snippets into a CherryTree workbook.

One thing we can probably agree on is that we don’t want to press too many buttons every time we take a screenshot. I wasn’t happy with most of the suggestions online and did some experimenting. This is what I have now:

I press a global shortcut (Ctrl-Alt-P). This invokes gnome-screenshot with predefined settings and my mouse turns into a cross cursor. I drag out a box. When I release the mouse button the image is placed on the clipboard. I click in CherryTree and Ctrl-V.
