在比较 Python 框架的系列文章的第三部分中,我们来了解 Tornado,它是为处理异步进程而构建的。

在这个由四部分组成的系列文章的前两篇中,我们介绍了 PyramidFlask Web 框架。我们已经构建了两次相同的应用程序,看到了一个完整的 DIY 框架和包含了更多功能的框架之间的异同。

现在让我们来看看另一个稍微不同的选择:Tornado 框架。Tornado 在很大程度上与 Flask 一样简单,但有一个主要区别:Tornado 是专门为处理异步进程而构建的。在我们本系列所构建的应用程序中,这种特殊的酱料(LCTT 译注:这里意思是 Tornado 的异步功能)在我们构建的 app 中并不是非常有用,但我们将看到在哪里可以使用它,以及它在更一般的情况下是如何工作的。

让我们继续前两篇文章中模式,首先从处理设置和配置开始。

Tornado 启动和配置

如果你一直关注这个系列,那么第一步应该对你来说习以为常。

$ mkdir tornado_todo
$ cd tornado_todo
$ pipenv install --python 3.6
$ pipenv shell
(tornado-someHash) $ pipenv install tornado

创建一个 setup.py 文件来安装我们的应用程序相关的东西:

(tornado-someHash) $ touch setup.py
# setup.py
from setuptools import setup, find_packages

requires = [
    'tornado',
    'tornado-sqlalchemy',
    'psycopg2',
]

setup(
    name='tornado_todo',
    version='0.0',
    description='A To-Do List built with Tornado',
    author='<Your name>',
    author_email='<Your email>',
    keywords='web tornado',
    packages=find_packages(),
    install_requires=requires,
    entry_points={
        'console_scripts': [
            'serve_app = todo:main',
        ],
    },
)

因为 Tornado 不需要任何外部配置,所以我们可以直接编写 Python 代码来让程序运行。让我们创建 todo 目录,并用需要的前几个文件填充它。

todo/
    __init__.py
    models.py
    views.py

就像 Flask 和 Pyramid 一样,Tornado 也有一些基本配置,放在 __init__.py 中。从 tornado.web 中,我们将导入 Application 对象,它将处理路由和视图的连接,包括数据库(当我们谈到那里时再说)以及运行 Tornado 应用程序所需的其它额外设置。

# __init__.py
from tornado.web import Application

def main():
    """Construct and serve the tornado application."""
    app = Application()

像 Flask 一样,Tornado 主要是一个 DIY 框架。当构建我们的 app 时,我们必须设置该应用实例。因为 Tornado 用它自己的 HTTP 服务器来提供该应用,我们必须设置如何提供该应用。首先,在 tornado.options.define 中定义要监听的端口。然后我们实例化 Tornado 的 HTTPServer,将该 Application 对象的实例作为参数传递给它。

# __init__.py
from tornado.httpserver import HTTPServer
from tornado.options import define, options
from tornado.web import Application

define('port', default=8888, help='port to listen on')

def main():
    """Construct and serve the tornado application."""
    app = Application()
    http_server = HTTPServer(app)
    http_server.listen(options.port)

当我们使用 define 函数时,我们最终会在 options 对象上创建属性。第一个参数位置的任何内容都将是属性的名称,分配给 default 关键字参数的内容将是该属性的值。

例如,如果我们将属性命名为 potato 而不是 port,我们可以通过 options.potato 访问它的值。

HTTPServer 上调用 listen 并不会启动服务器。我们必须再做一步,找一个可以监听请求并返回响应的工作应用程序,我们需要一个输入输出循环。幸运的是,Tornado 以 tornado.ioloop.IOLoop 的形式提供了开箱即用的功能。

# __init__.py
from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop
from tornado.options import define, options
from tornado.web import Application

define('port', default=8888, help='port to listen on')

def main():
    """Construct and serve the tornado application."""
    app = Application()
    http_server = HTTPServer(app)
    http_server.listen(options.port)
    print('Listening on http://localhost:%i' % options.port)
    IOLoop.current().start()

我喜欢某种形式的 print 语句,来告诉我什么时候应用程序正在提供服务,这是我的习惯。如果你愿意,可以不使用 print

我们以 IOLoop.current().start() 开始我们的 I/O 循环。让我们进一步讨论输入,输出和异步性。

Python 中的异步和 I/O 循环的基础知识

请允许我提前说明,我绝对,肯定,一定并且放心地说不是异步编程方面的专家。就像我写的所有内容一样,接下来的内容源于我对这个概念的理解的局限性。因为我是人,可能有很深很深的缺陷。

异步程序的主要问题是:

* 数据如何进来?
* 数据如何出去?
* 什么时候可以在不占用我全部注意力情况下运行某个过程?

由于全局解释器锁(GIL),Python 被设计为一种单线程语言。对于 Python 程序必须执行的每个任务,其线程执行的全部注意力都集中在该任务的持续时间内。我们的 HTTP 服务器是用 Python 编写的,因此,当接收到数据(如 HTTP 请求)时,服务器的唯一关心的是传入的数据。这意味着,在大多数情况下,无论是程序需要运行还是处理数据,程序都将完全消耗服务器的执行线程,阻止接收其它可能的数据,直到服务器完成它需要做的事情。

在许多情况下,这不是太成问题。典型的 Web 请求,响应周期只需要几分之一秒。除此之外,构建 HTTP 服务器的套接字可以维护待处理的传入请求的积压。因此,如果请求在该套接字处理其它内容时进入,则它很可能只是在处理之前稍微排队等待一会。对于低到中等流量的站点,几分之一秒的时间并不是什么大问题,你可以使用多个部署的实例以及 NGINX 等负载均衡器来为更大的请求负载分配流量。

但是,如果你的平均响应时间超过一秒钟,该怎么办?如果你使用来自传入请求的数据来启动一些长时间的过程(如机器学习算法或某些海量数据库查询),该怎么办?现在,你的单线程 Web 服务器开始累积一个无法寻址的积压请求,其中一些请求会因为超时而被丢弃。这不是一种选择,特别是如果你希望你的服务在一段时间内是可靠的。

异步 Python 程序登场。重要的是要记住因为它是用 Python 编写的,所以程序仍然是一个单线程进程。除非特别标记,否则在异步程序中仍然会阻塞执行。

但是,当异步程序结构正确时,只要你指定某个函数应该具有这样的能力,你的异步 Python 程序就可以“搁置”长时间运行的任务。然后,当搁置的任务完成并准备好恢复时,异步控制器会收到报告,只要在需要时管理它们的执行,而不会完全阻塞对新输入的处理。

这有点夸张,所以让我们用一个人类的例子来证明。

带回家吧

我经常发现自己在家里试图完成很多家务,但没有多少时间来做它们。在某一天,积压的家务可能看起来像:

* 做饭(20 分钟准备,40 分钟烹饪)
* 洗碗(60 分钟)
* 洗涤并擦干衣物(30 分钟洗涤,每次干燥 90 分钟)
* 真空清洗地板(30 分钟)

如果我是一个传统的同步程序,我会亲自完成每项任务。在我考虑处理任何其他事情之前,每项任务都需要我全神贯注地完成。因为如果没有我的全力关注,什么事情都完成不了。所以我的执行顺序可能如下:

1. 完全专注于准备和烹饪食物,包括等待食物烹饪(60 分钟)
2. 将脏盘子移到水槽中(65 分钟过去了)
3. 清洗所有盘子(125 分钟过去了)
4. 开始完全专注于洗衣服,包括等待洗衣机洗完,然后将衣物转移到烘干机,再等烘干机完成( 250 分钟过去了)
5. 对地板进行真空吸尘(280 分钟了)

从头到尾完成所有事情花费了 4 小时 40 分钟。

我应该像异步程序一样聪明地工作,而不是努力工作。我的家里到处都是可以为我工作的机器,而不用我一直努力工作。同时,现在我可以将注意力转移真正需要的东西上。

我的执行顺序可能看起来像:

1. 将衣物放入洗衣机并启动它(5 分钟)
2. 在洗衣机运行时,准备食物(25 分钟过去了)
3. 准备好食物后,开始烹饪食物(30 分钟过去了)
4. 在烹饪食物时,将衣物从洗衣机移到烘干机机中开始烘干(35 分钟过去了)
5. 当烘干机运行中,且食物仍在烹饪时,对地板进行真空吸尘(65 分钟过去了)
6. 吸尘后,将食物从炉子中取出并装盘子入洗碗机(70 分钟过去了)
7. 运行洗碗机(130 分钟完成)

现在花费的时间下降到 2 小时 10 分钟。即使我允许在作业之间切换花费更多时间(总共 10-20 分钟)。如果我等待着按顺序执行每项任务,我花费的时间仍然只有一半左右。这就是将程序构造为异步的强大功能。

那么 I/O 循环在哪里?

一个异步 Python 程序的工作方式是从某个外部源(输入)获取数据,如果某个进程需要,则将该数据转移到某个外部工作者(输出)进行处理。当外部进程完成时,Python 主程序会收到提醒,然后程序获取外部处理(输入)的结果,并继续这样其乐融融的方式。

当数据不在 Python 主程序手中时,主程序就会被释放来处理其它任何事情。包括等待全新的输入(如 HTTP 请求)和处理长时间运行的进程的结果(如机器学习算法的结果,长时间运行的数据库查询)。主程序虽仍然是单线程的,但成了事件驱动的,它对程序处理的特定事件会触发动作。监听这些事件并指示应如何处理它们的主要是 I/O 循环在工作。

我知道,我们走了很长的路才得到这个重要的解释,但我希望在这里传达的是,它不是魔术,也不是某种复杂的并行处理或多线程工作。全局解释器锁仍然存在,主程序中任何长时间运行的进程仍然会阻塞其它任何事情的进行,该程序仍然是单线程的。然而,通过将繁琐的工作外部化,我们可以将线程的注意力集中在它需要注意的地方。

这有点像我上面的异步任务。当我的注意力完全集中在准备食物上时,它就是我所能做的一切。然而,当我能让炉子帮我做饭,洗碗机帮我洗碗,洗衣机和烘干机帮我洗衣服时,我的注意力就会被释放出来,去做其它事情。当我被提醒,我的一个长时间运行的任务已经完成并准备再次处理时,如果我的注意力是空闲的,我可以获取该任务的结果,并对其做下一步需要做的任何事情。

Tornado 路由和视图

尽管经历了在 Python 中讨论异步的所有麻烦,我们还是决定暂不使用它。先来编写一个基本的 Tornado 视图。

与我们在 Flask 和 Pyramid 实现中看到的基于函数的视图不同,Tornado 的视图都是基于类的。这意味着我们将不在使用单独的、独立的函数来规定如何处理请求。相反,传入的 HTTP 请求将被捕获并将其分配为我们定义的类的一个属性。然后,它的方法将处理相应的请求类型。

让我们从一个基本的视图开始,即在屏幕上打印 “Hello, World”。我们为 Tornado 应用程序构造的每个基于类的视图都必须继承 tornado.web 中的 RequestHandler 对象。这将设置我们需要(但不想写)的所有底层逻辑来接收请求,同时构造正确格式的 HTTP 响应。

from tornado.web import RequestHandler

class HelloWorld(RequestHandler):
    """Print 'Hello, world!' as the response body."""

    def get(self):
        """Handle a GET request for saying Hello World!."""
        self.write("Hello, world!")

因为我们要处理 GET 请求,所以我们声明(实际上是重写)了 get 方法。我们提供文本或 JSON 可序列化对象,用 self.write 写入响应体。之后,我们让 RequestHandler 来做在发送响应之前必须完成的其它工作。

就目前而言,此视图与 Tornado 应用程序本身并没有实际连接。我们必须回到 __init__.py,并稍微更新 main 函数。以下是新的内容:

# __init__.py
from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop
from tornado.options import define, options
from tornado.web import Application
from todo.views import HelloWorld

define('port', default=8888, help='port to listen on')

def main():
    """Construct and serve the tornado application."""
    app = Application([
        ('/', HelloWorld)
    ])
    http_server = HTTPServer(app)
    http_server.listen(options.port)
    print('Listening on http://localhost:%i' % options.port)
    IOLoop.current().start()

我们做了什么

我们将 views.py 文件中的 HelloWorld 视图导入到脚本 __init__.py 的顶部。然后我们添加了一个路由-视图对应的列表,作为 Application 实例化的第一个参数。每当我们想要在应用程序中声明一个路由时,它必须绑定到一个视图。如果需要,可以对多个路由使用相同的视图,但每个路由必须有一个视图。

我们可以通过在 setup.py 中启用的 serve_app 命令来运行应用程序,从而确保这一切都能正常工作。查看 http://localhost:8888/ 并看到它显示 “Hello, world!”。

当然,在这个领域中我们还能做更多,也将做更多,但现在让我们来讨论模型吧。

连接数据库

如果我们想要保留数据,就需要连接数据库。与 Flask 一样,我们将使用一个特定于框架的 SQLAchemy 变体,名为 tornado-sqlalchemy

为什么要使用它而不是 SQLAlchemy 呢?好吧,其实 tornado-sqlalchemy 具有简单 SQLAlchemy 的所有优点,因此我们仍然可以使用通用的 Base 声明模型,并使用我们习以为常的所有列数据类型和关系。除了我们已经惯常了解到的,tornado-sqlalchemy 还为其数据库查询功能提供了一种可访问的异步模式,专门用于与 Tornado 现有的 I/O 循环一起工作。

我们通过将 tornado-sqlalchemypsycopg2 添加到 setup.py 到所需包的列表并重新安装包来创建环境。在 models.py 中,我们声明了模型。这一步看起来与我们在 Flask 和 Pyramid 中已经看到的完全一样,所以我将跳过全部声明,只列出了 Task 模型的必要部分。

# 这不是完整的 models.py, 但是足够看到不同点
from tornado_sqlalchemy import declarative_base

Base = declarative_base

class Task(Base):
    # 等等,因为剩下的几乎所有的东西都一样 ...

我们仍然需要将 tornado-sqlalchemy 连接到实际应用程序。在 __init__.py 中,我们将定义数据库并将其集成到应用程序中。

# __init__.py
from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop
from tornado.options import define, options
from tornado.web import Application
from todo.views import HelloWorld

# add these
import os
from tornado_sqlalchemy import make_session_factory

define('port', default=8888, help='port to listen on')
factory = make_session_factory(os.environ.get('DATABASE_URL', ''))

def main():
    """Construct and serve the tornado application."""
    app = Application([
        ('/', HelloWorld)
    ],
        session_factory=factory
    )
    http_server = HTTPServer(app)
    http_server.listen(options.port)
    print('Listening on http://localhost:%i' % options.port)
    IOLoop.current().start()

就像我们在 Pyramid 中传递的会话工厂一样,我们可以使用 make_session_factory 来接收数据库 URL 并生成一个对象,这个对象的唯一目的是为视图提供到数据库的连接。然后我们将新创建的 factory 传递给 Application 对象,并使用 session_factory 关键字参数将它绑定到应用程序中。

最后,初始化和管理数据库与 Flask 和 Pyramid 相同(即,单独的 DB 管理脚本,与 Base 对象一起工作等)。它看起来很相似,所以在这里我就不介绍了。

回顾视图

Hello,World 总是适合学习基础知识,但我们需要一些真实的,特定应用程序的视图。

让我们从 info 视图开始。

# views.py
import json
from tornado.web import RequestHandler

class InfoView(RequestHandler):
    """只允许 GET 请求"""
    SUPPORTED_METHODS = ["GET"]

    def set_default_headers(self):
        """设置默认响应头为 json 格式的"""
        self.set_header("Content-Type", 'application/json; charset="utf-8"')

    def get(self):
        """列出这个 API 的路由"""
        routes = {
            'info': 'GET /api/v1',
            'register': 'POST /api/v1/accounts',
            'single profile detail': 'GET /api/v1/accounts/<username>',
            'edit profile': 'PUT /api/v1/accounts/<username>',
            'delete profile': 'DELETE /api/v1/accounts/<username>',
            'login': 'POST /api/v1/accounts/login',
            'logout': 'GET /api/v1/accounts/logout',
            "user's tasks": 'GET /api/v1/accounts/<username>/tasks',
            "create task": 'POST /api/v1/accounts/<username>/tasks',
            "task detail": 'GET /api/v1/accounts/<username>/tasks/<id>',
            "task update": 'PUT /api/v1/accounts/<username>/tasks/<id>',
            "delete task": 'DELETE /api/v1/accounts/<username>/tasks/<id>'
        }
        self.write(json.dumps(routes))

有什么改变吗?让我们从上往下看。

我们添加了 SUPPORTED_METHODS 类属性,它是一个可迭代对象,代表这个视图所接受的请求方法,其他任何方法都将返回一个 405 状态码。当我们创建 HelloWorld 视图时,我们没有指定它,主要是当时有点懒。如果没有这个类属性,此视图将响应任何试图绑定到该视图的路由的请求。

我们声明了 set_default_headers 方法,它设置 HTTP 响应的默认头。我们在这里声明它,以确保我们返回的任何响应都有一个 "Content-Type""application/json" 类型。

我们将 json.dumps(some_object) 添加到 self.write 的参数中,因为它可以很容易地构建响应主体的内容。

现在已经完成了,我们可以继续将它连接到 __init__.py 中的主路由。

# __init__.py
from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop
from tornado.options import define, options
from tornado.web import Application
from todo.views import InfoView

# 添加这些
import os
from tornado_sqlalchemy import make_session_factory

define('port', default=8888, help='port to listen on')
factory = make_session_factory(os.environ.get('DATABASE_URL', ''))

def main():
    """Construct and serve the tornado application."""
    app = Application([
        ('/', InfoView)
    ],
        session_factory=factory
    )
    http_server = HTTPServer(app)
    http_server.listen(options.port)
    print('Listening on http://localhost:%i' % options.port)
    IOLoop.current().start()

我们知道,还需要编写更多的视图和路由。每个都会根据需要放入 Application 路由列表中,每个视图还需要一个 set_default_headers 方法。在此基础上,我们还将创建 send_response 方法,它的作用是将响应与我们想要给响应设置的任何自定义状态码打包在一起。由于每个视图都需要这两个方法,因此我们可以创建一个包含它们的基类,这样每个视图都可以继承基类。这样,我们只需要编写一次。

# views.py
import json
from tornado.web import RequestHandler

class BaseView(RequestHandler):
    """Base view for this application."""

    def set_default_headers(self):
        """Set the default response header to be JSON."""
        self.set_header("Content-Type", 'application/json; charset="utf-8"')

    def send_response(self, data, status=200):
        """Construct and send a JSON response with appropriate status code."""
        self.set_status(status)
        self.write(json.dumps(data))

对于我们即将编写的 TaskListView 这样的视图,我们还需要一个到数据库的连接。我们需要 tornado_sqlalchemy 中的 SessionMixin 在每个视图类中添加一个数据库会话。我们可以将它放在 BaseView 中,这样,默认情况下,从它继承的每个视图都可以访问数据库会话。

# views.py
import json
from tornado_sqlalchemy import SessionMixin
from tornado.web import RequestHandler

class BaseView(RequestHandler, SessionMixin):
    """Base view for this application."""

    def set_default_headers(self):
        """Set the default response header to be JSON."""
        self.set_header("Content-Type", 'application/json; charset="utf-8"')

    def send_response(self, data, status=200):
        """Construct and send a JSON response with appropriate status code."""
        self.set_status(status)
        self.write(json.dumps(data))

只要我们修改 BaseView 对象,在将数据发布到这个 API 时,我们就应该定位到这里。

当 Tornado(从 v.4.5 开始)使用来自客户端的数据并将其组织起来到应用程序中使用时,它会将所有传入数据视为字节串。但是,这里的所有代码都假设使用 Python 3,因此我们希望使用的唯一字符串是 Unicode 字符串。我们可以为这个 BaseView 类添加另一个方法,它的工作是将输入数据转换为 Unicode,然后再在视图的其他地方使用。

如果我们想要在正确的视图方法中使用它之前转换这些数据,我们可以重写视图类的原生 prepare 方法。它的工作是在视图方法运行前运行。如果我们重写 prepare 方法,我们可以设置一些逻辑来运行,每当收到请求时,这些逻辑就会执行字节串到 Unicode 的转换。

# views.py
import json
from tornado_sqlalchemy import SessionMixin
from tornado.web import RequestHandler

class BaseView(RequestHandler, SessionMixin):
    """Base view for this application."""

    def prepare(self):
        self.form_data = {
            key: [val.decode('utf8') for val in val_list]
            for key, val_list in self.request.arguments.items()
        }

    def set_default_headers(self):
        """Set the default response header to be JSON."""
        self.set_header("Content-Type", 'application/json; charset="utf-8"')

    def send_response(self, data, status=200):
        """Construct and send a JSON response with appropriate status code."""
        self.set_status(status)
        self.write(json.dumps(data))

如果有任何数据进入,它将在 self.request.arguments 字典中找到。我们可以通过键访问该数据库,并将其内容(始终是列表)转换为 Unicode。因为这是基于类的视图而不是基于函数的,所以我们可以将修改后的数据存储为一个实例属性,以便以后使用。我在这里称它为 form_data,但它也可以被称为 potato。关键是我们可以存储提交给应用程序的数据。

异步视图方法

现在我们已经构建了 BaseaView,我们可以构建 TaskListView 了,它会继承 BaseaView

正如你可以从章节标题中看到的那样,以下是所有关于异步性的讨论。TaskListView 将处理返回任务列表的 GET 请求和用户给定一些表单数据来创建新任务的 POST 请求。让我们首先来看看处理 GET 请求的代码。

# all the previous imports
import datetime
from tornado.gen import coroutine
from tornado_sqlalchemy import as_future
from todo.models import Profile, Task

# the BaseView is above here
class TaskListView(BaseView):
    """View for reading and adding new tasks."""
    SUPPORTED_METHODS = ("GET", "POST",)

    @coroutine
    def get(self, username):
        """Get all tasks for an existing user."""
        with self.make_session() as session:
            profile = yield as_future(session.query(Profile).filter(Profile.username == username).first)
            if profile:
                tasks = [task.to_dict() for task in profile.tasks]
                self.send_response({
                    'username': profile.username,
                    'tasks': tasks
                })

这里的第一个主要部分是 @coroutine 装饰器,它从 tornado.gen 导入。任何具有与调用堆栈的正常流程不同步的 Python 可调用部分实际上是“协程”,即一个可以与其它协程一起运行的协程。在我的家务劳动的例子中,几乎所有的家务活都是一个共同的例行协程。有些阻止了例行协程(例如,给地板吸尘),但这种例行协程只会阻碍我开始或关心其它任何事情的能力。它没有阻止已经启动的任何其他协程继续进行。

Tornado 提供了许多方法来构建一个利用协程的应用程序,包括允许我们设置函数调用锁,同步异步协程的条件,以及手动修改控制 I/O 循环的事件系统。

这里使用 @coroutine 装饰器的唯一条件是允许 get 方法将 SQL 查询作为后台进程,并在查询完成后恢复,同时不阻止 Tornado I/O 循环去处理其他传入的数据源。这就是关于此实现的所有“异步”:带外数据库查询。显然,如果我们想要展示异步 Web 应用程序的魔力和神奇,那么一个任务列表就不是好的展示方式。

但是,这就是我们正在构建的,所以让我们来看看方法如何利用 @coroutine 装饰器。SessionMixin 混合到 BaseView 声明中,为我们的视图类添加了两个方便的,支持数据库的属性:sessionmake_session。它们的名字相似,实现的目标也相当相似。

self.session 属性是一个关注数据库的会话。在请求-响应周期结束时,在视图将响应发送回客户端之前,任何对数据库的更改都被提交,并关闭会话。

self.make_session 是一个上下文管理器和生成器,可以动态构建和返回一个全新的会话对象。第一个 self.session 对象仍然存在。无论如何,反正 make_session 会创建一个新的。make_session 生成器还为其自身提供了一个功能,用于在其上下文(即缩进级别)结束时提交和关闭它创建的会话。

如果你查看源代码,则赋值给 self.session 的对象类型与 self.make_session 生成的对象类型之间没有区别,不同之处在于它们是如何被管理的。

使用 make_session 上下文管理器,生成的会话仅属于上下文,在该上下文中开始和结束。你可以使用 make_session 上下文管理器在同一个视图中打开,修改,提交以及关闭多个数据库会话。

self.session 要简单得多,当你进入视图方法时会话已经打开,在响应被发送回客户端之前会话就已提交。

虽然读取文档片段PyPI 示例都说明了上下文管理器的使用,但是没有说明 self.session 对象或由 self.make_session 生成的 session 本质上是不是异步的。当我们启动查询时,我们开始考虑内置于 tornado-sqlalchemy 中的异步行为。

tornado-sqlalchemy 包为我们提供了 as_future 函数。它的工作是装饰 tornado-sqlalchemy 会话构造的查询并 yield 其返回值。如果视图方法用 @coroutine 装饰,那么使用 yield as_future(query) 模式将使封装的查询成为一个异步后台进程。I/O 循环会接管等待查询的返回值和 as_future 创建的 future 对象的解析。

要访问 as_future(query) 的结果,你必须从它 yield。否则,你只能获得一个未解析的生成器对象,并且无法对查询执行任何操作。

这个视图方法中的其他所有内容都与之前课堂上的类似,与我们在 Flask 和 Pyramid 中看到的内容类似。

post 方法看起来非常相似。为了保持一致性,让我们看一下 post 方法以及它如何处理用 BaseView 构造的 self.form_data

@coroutine
def post(self, username):
    """Create a new task."""
    with self.make_session() as session:
        profile = yield as_future(session.query(Profile).filter(Profile.username == username).first)
        if profile:
            due_date = self.form_data['due_date'][0]
            task = Task(
                name=self.form_data['name'][0],
                note=self.form_data['note'][0],
                creation_date=datetime.now(),
                due_date=datetime.strptime(due_date, '%d/%m/%Y %H:%M:%S') if due_date else None,
                completed=self.form_data['completed'][0],
                profile_id=profile.id,
                profile=profile
            )
            session.add(task)
            self.send_response({'msg': 'posted'}, status=201)

正如我所说,这是我们所期望的:

  * 与我们在 get 方法中看到的查询模式相同   * 构造一个新的 Task 对象的实例,用 form_data 的数据填充   * 添加新的 Task 对象(但不提交,因为它由上下文管理器处理!)到数据库会话   * 将响应发送给客户端

这样我们就有了 Tornado web 应用程序的基础。其他内容(例如,数据库管理和更多完整应用程序的视图)实际上与我们在 Flask 和 Pyramid 应用程序中看到的相同。

关于使用合适的工具完成合适的工作的一点想法

在我们继续浏览这些 Web 框架时,我们开始看到它们都可以有效地处理相同的问题。对于像这样的待办事项列表,任何框架都可以完成这项任务。但是,有些 Web 框架比其它框架更适合某些工作,这具体取决于对你来说什么“更合适”和你的需求。

虽然 Tornado 显然和 Pyramid 或 Flask 一样可以处理相同工作,但将它用于这样的应用程序实际上是一种浪费,这就像开车从家走一个街区(LCTT 译注:这里意思应该是从家开始走一个街区只需步行即可)。是的,它可以完成“旅行”的工作,但短途旅行不是你选择汽车而不是自行车或者使用双脚的原因。

根据文档,Tornado 被称为 &ldquoython Web 框架和异步网络库”。在 Python Web 框架生态系统中很少有人喜欢它。如果你尝试完成的工作需要(或将从中获益)以任何方式、形状或形式的异步性,使用 Tornado。如果你的应用程序需要处理多个长期连接,同时又不想牺牲太多性能,选择 Tornado。如果你的应用程序是多个应用程序,并且需要线程感知以准确处理数据,使用 Tornado。这是它最有效的地方。

用你的汽车做“汽车的事情”,使用其他交通工具做其他事情。

向前看,进行一些深度检查

谈到使用合适的工具来完成合适的工作,在选择框架时,请记住应用程序的范围和规模,包括现在和未来。到目前为止,我们只研究了适用于中小型 Web 应用程序的框架。本系列的下一篇也是最后一篇将介绍最受欢迎的 Python 框架之一 Django,它适用于可能会变得更大的大型应用程序。同样,尽管它在技术上能够并且将会处理待办事项列表问题,但请记住,这不是它的真正用途。我们仍然会通过它来展示如何使用它来构建应用程序,但我们必须牢记框架的意图以及它是如何反映在架构中的:

  • Flask: 适用于小型,简单的项目。它可以使我们轻松地构建视图并将它们快速连接到路由,它可以简单地封装在一个文件中。 
  • Pyramid: 适用于可能增长的项目。它包含一些配置来启动和运行。应用程序组件的独立领域可以很容易地划分并构建到任意深度,而不会忽略中央应用程序。
  • Tornado: 适用于受益于精确和有意识的 I/O 控制的项目。它允许协程,并轻松公开可以控制如何接收请求或发送响应以及何时发生这些操作的方法。
  • Django:(我们将会看到)意味着可能会变得更大的东西。它有着非常庞大的生态系统,包括大量插件和模块。它非常有主见的配置和管理,以保持所有不同部分在同一条线上。

无论你是从本系列的第一篇文章开始阅读,还是稍后才加入的,都要感谢阅读!请随意留下问题或意见。下次再见时,我手里会拿着 Django。

感谢 Python BDFL

我必须把功劳归于它应得的地方,非常感谢 Guido van Rossum,不仅仅是因为他创造了我最喜欢的编程语言。

PyCascades 2018 期间,我很幸运的不仅做了基于这个文章系列的演讲,而且还被邀请参加了演讲者的晚宴。整个晚上我都坐在 Guido 旁边,不停地问他问题。其中一个问题是,在 Python 中异步到底是如何工作的,但他没有一点大惊小怪,而是花时间向我解释,让我开始理解这个概念。他后来推特给我发了一条消息:是用于学习异步 Python 的广阔资源。我随后在三个月内阅读了三次,然后写了这篇文章。你真是一个非常棒的人,Guido!

          Vision Positionning Experiments using SKYVIPER      Cache   Translate Page      

@ppoirier wrote:

Thanks to the hard work from Andrea Belloni @anbello ,@chobitsfan , @SubMishMar and with the help of Randy @rmackay9 , we are now able to experiment with Vision Positioning and going toward more advanced system like Visual Odometry and Visual SLAM.

I present here an experiment that can be relatively easy to replicate with an off-the-shelf inexpensive Micro Drone that can be used safely in an indoor space: the Skyviper Journey. Just a friendly reminder before you start, this is advanced stuff and you need to know ROS , Linux, Python and you are able to configure your network and WIFI in order to make it work. I am available to discuss about the Vision System but for the basics, there are tons of resources on google and ArduPilot wiki is quite good http://ardupilot.org/dev/docs/ros.html

Here is the general configuration, 2 Laptops are used for this setup. First one is a Ubuntu running ROS to capture the Skyviper Camera looking down at the Aruco Grid on a GSTREAMER rstp stream that is processed with OpenCV to extract the camera pose. This topic is then transformed into MavLink compatible https://mavlink.io/en/messages/common.html#VISION_POSITION_ESTIMATE and transmitted to the vehicle using Mavros. Second Laptop running Win 10 and Mission Planner for Control using Joystick as RC Override and display vehicle position on map.


What do we need:
1- Ubuntu 16.04 and ROS kinetic desktop full installed and working
2- Gstreamer 1.x (This should preloaded with Ubuntu 16)
3- Mavros & Mavros Extra Installed
4- Ardupilot and tools installed
5-A fully working and prop balanced SkyViper in AP Mode (192.168.99.1)

BUILD & CONFIGURE SKYVIPER
a- Build Skyviper from Master:

  • ./waf configure --board skyviper-f412
  • ./waf build --target=bin/arducopter

b- Upload the abin file using the web interface @192.168.99.1/upgrade.html
c- Set Parameters within mission planner
d- The new build will disable usage of the original DSM transmitter (Issue Opened). You can use a USB Joystick connected to Mission Planner and configure as below (add Arm & Desarm buttons) and check that axes are OK using Radio Calibration Menu.
e- Do a test flight in manual mode to verify that all is OK

ROS
a- Using catkin tools , build a catkin_ws
b- clone @anbello github https://github.com/anbello/aruco_gridboard
c- clone gscam https://github.com/ros-drivers/gscam and set -DGSTREAMER_VERSION_1_x=On
d- catkin build and source
e- Set SKYVIPER camera resolution to 640 x 360 using the web page
f- Calibrate camera using the ROS GRID method and add the camera yaml in the launch file
g- Build the ARUCO GridBoard and calibrate the layout file (3x3layout.yaml)

Test by setting the debug to True in detection launch file
Connect WIFI to SKYVIPER

  • roscore
  • roslaunch gscam skyviper.launch (you can chek with rqt_imageview)
  • roslaunch aruco_gridboard-detection.launch

You should be able to see the image with the overlay XYZ axes and data being displayed correspond to Aruco Pose.

Then you can launch MAVROS , but we need to set mavproxy as the SKYVIPER allows for just one port (14550) opening. This is my command, it may vary depending on your setup:

mavproxy.py --master=udp:0.0.0.0:14550 --out udp:127.0.0.1:14551 --out udp:192.168.2.233:14552

You can connect Mission Planner @14552 and activate the Joystick

Launch Mavros
roslaunch mavros apm.launch fcu_url:=udp://127.0.0.1:14551@

The signal should look like this on Windows QGC Analyse Widget

Go on Mission Planner and Right Click on the Map to set EKF Home, yould see vehicle appears. Zoom to maximum

Hold the Skyviper in you hands and walk around the ARUCO Grid, you must see the vehicle move accordingly on Mission Planner Map (look at the video above).

Set MP in Loiter , ARM and takeoff with Joystick, fly over the Aruco Grid, and if the Skyviper is well tuned and has minimal vibration, it should hold over the grid with minimum drift. Voilà !!

You can adjust the Camera capture Delay with EXTNAV_DELAY (work in progress)

PLEASE NOTE: This is a draft, more information and more code will be added soon.

          借助 Home Assistant,做一个能「看见」我赖床的智能闹钟 | 2018 年度征文      Cache   Translate Page      

编注:本文是「我的 2018 年度关键词」年度征文活动的第 5 篇入围文章,本文仅代表作者本人观点,少数派对标题和排版略作调整。
想了解如何参与本次征文,赢取各种丰厚奖品,你可以 点此查看 活动规则和奖品清单。


前言

在2017年年底,我给自己的2018年定了一个挑战,那就是尝试学习一门编程语言。在之前,这对我是一片空白。这个个人挑战,既不追求有什么具体的目标,也不会对我的工作有什么直接的帮助,纯粹是要逼自己锻炼自学的能力,拓展一下 scope。

18年年底逐渐来临,一个 idea 逐渐孕育。

作为一个晚睡癌者,虽然我已经特地租到离公司只有15分钟步行时间的地方,但随着我睡过闹钟的病症越来越严重,我有了一个想法:

能不能有这样一个闹钟?设定在每天的起床 deadline 上,到点就能够智能检测我是不是在赖床;一旦发现我又要迟到,就放摇滚音乐把我叫醒。

在2018年的 Black Friday,我托朋友海淘了一个 Amazon Echo Dot,燃起了我要 hack 一下这个小东西的热情。在18年最后的两个星期,我决定抡起袖子开干。

中途一度觉得搞不定,但熬了一轮夜、掉了一轮头发之后,搞出来的效果居然还不错,效果请戳:

今天就和广大晚睡癌病友们分享下这个项目。

方案研究

一开始的方案设想很简单:

作为独居青年我没有办法能拍到自己真实睡觉的样子,请大家接受我的自拍谢谢
作为独居青年我没有办法能拍到自己真实睡觉的样子,请大家接受我的自拍谢谢

但是,经过一番研究,我还是没有找到方法 hack 进 Alexa。不过,作为一名灵活的产品经理,我决定 work around 一下,改成下面这样子依然能上线跑噢:

最终可以执行的流程,因为 Hack 不进 Alexa
最终可以执行的流程,因为 Hack 不进 Alexa

经过一番研究,我确定了这个项目所需的软硬件方案。基于 MVP 原则(简单来说就是万一搞不成了不要浪费太多钱和时间的原则),我从床底下拿出了尘封已久的安卓机皇:oneplus one

下面就是初步列出的方案:

模块 实现方式 所需硬件/软件
整体流程控制 Home Assistant 一台能够运行 Linux 的机器,例如一台安卓手机
视觉识别 摄像头(local)+深度学习模型接口(server) 一台有摄像头的机器,例如一台安卓手机;一台能够部署模型并暴露接口的VPS
音频 Text-to-speech 带麦克风的机器,例如一台安卓手机

于是流程图,又可以继续细化。

加上了硬件模块划分的流程图
加上了硬件模块划分的流程图

这个在2018年年尾才确定的项目,我觉得是一个很好的选择。因为麻雀虽小,但贯穿了过去一年的所有重要知识点。

模块 知识点 技能点
部署 Home Assistant Linux 基础知识 开源项目理解,以及文档查阅能力
Home Assistant 自动化开发 Python + 硬件基础理解 业务流程设计能力
图像识别 深度学习模型训练 机器学习的基础理解,以及开源的优秀框架运用
Client-Server 交互 深度学习模型部署API接口 对API接口交互的理解

像很多新手一样,2017年底刚开始学习时,我模糊地以为我的学习重点是 Python 这门语言。但慢慢走下去,才发现具体的语言本身毫不重要,像上面所展示的知识点,完全可以把语言抽离出来,更多是编程利于的框架性理解。一年过后更重要的收获,是我对互联网在实现层面的理解更深了。

分享科技相关资讯的网站有不少,但我一直觉得少数派还是一个小小的极客社区:对比较 hardcore 而相对枯燥的内容很宽容,社区内也很鼓励动手能力。我不相信编程是一种囿于职业、专业的技能。只要愿意学习,每个人都几乎可以学习任何事情,编程自然也绝不例外。不过,虽然编程不是少数人的特权,但肯学习和动手实践的人总是少数派。

这次项目的分享,会分为两篇,可能还是会比较 hardcore 和枯燥:

  1. 第一篇围绕 Home Assistant 的搭建;
  2. 第二篇围绕用深度学习模型完成图像分类预测的实现

本文为第一篇,大部分的篇幅会和 Home Assistant 相关。我会在前半部分介绍比较浅显和有趣的内容,尽量面向所有读者,感兴趣的朋友看完前半部分,有了大体的了解就差不多了。而后半部分则会比较复杂,涉及 Home Assitant 的开发部分,代码也会出现比较多。普通读者可能会感到头疼,这不要紧,因为只是供打算动手做设计的朋友参考的。


什么是 Home Assistant?

Home Assistant 是一个开源的智能家居自动化平台。它特点是运行在局域网内的设备上,相对比较注重隐私。

智能家居的最大问题之一,就是标准无法统一。在开源社区的努力下,已经支持1000多种硬件和软件接入。接入的软硬件,可以统一串联起来,设置自动化流程。包括我手头上零零碎碎的硬件也是各个品牌的,基于这个平台的特点,我选择使用该开源项目作为主要的开发平台。

Home Assistant 核心概念理解:组件、服务、状态

在 Home Assistant 设计自动化中,我们总是在和这几个关键概念打交道:

  1. 组件:可以理解为 HA 允许接入的硬件或者软件服务,例如小米的灯(硬件)、摄像头(硬件)、麦克风(硬件)、脚本传感器(软件)、甚至自己编写的 custom component(软件,这个也是我们这次项目中主要使用到的能串起整个流程的核心组件)
  2. 服务:一个组件,会对外提供服务,例如一盏灯可以提供开关灯的服务,一个麦克风可以提供说话的服务。自己编写的一些脚本组件,也可以对外提供触发的服务
  3. 状态:一盏灯在当前是否开启着的,这是一个状态;

智能家居是一个非常复杂的场景,Home Assistant 作为一个智能家居平台,在设计之初就要考虑到开放性和复杂性。组件、服务、状态,这三个概念相当简洁,又全面,确实是非常优雅的设计。

HA 模块拆解

承接上面对核心概念的概念,我们终于可以把项目中设计到的功能点,在 Home Assistant 的框架中进行拆解。

模块 组件(component) 涉及服务
在面板上可以输入时间的地方 Input Datetime(输入时间) 不涉及
判断当前时间是否为工作日&当前时间 Shell Command(命令行) 暴露一个检查当前时间的服务
判断&闹钟主体(视觉部分) Android IP webcam(摄像头) snapshot 拍照服务
判断&闹钟主体(闹钟部分) TTS (text-to-speech) + Kodi(麦克风) google.say 用上google 文字转音频服务

敲定软件方案,数据流转也已经清晰确定
敲定软件方案,数据流转也已经清晰确定


实战篇

现在开始进入到复杂的部分,会设计到 Home Assistant 的开发模块,也会涉及比较多的代码。抛砖引玉,供想要动手调教的朋友参考。

如何部署 Home Assistant?

本质上来讲,可以部署在任何 Linux 的环境中,包括树莓派、Macbook、以及任意可以运行 Linux 的设备上。如果你使用树莓派,建议参阅 @墨澜 之前分享的一系列教程,特别是 Home Assistant + 树莓派:强大的智能家居系统 · 安装篇

我手上刚好有一台旧的安卓手机,就想办法直接在上面部署了,参考分享帖 Ubuntu安装HomeAssistant教程 步骤如下:

  1. 安装 Linux Deploy APP,在家里的 Wifi 下启动
  2. 使用你的电脑 ssh 连入安卓终端,安装 Python3、pip 等工具
  3. 激活一个 Python3 的虚拟环境
  4. 安装 Home Assistant
    pip install homeassistant
    
  5. 启动 Home Assistant
    hass --open-ui
    
    然后,用你的浏览器访问 <存管服务器的IP>:8123 应该就可以正常访问。

文档研究基础篇:如何查询、添加组件

当 HA 成功运行后,要添加组件都在主目录的 configuration.yaml 中进行编辑和添加。
朋友们,让我们打开文档官方文档:组件,可以在这里搜索上千样软硬件的接入方法。

例如,Text-to-speech,只需要在configuration.yaml中添加下面这些代码:

# yaml 文件的关键点在于缩进要正确
# Text to speech
tts:
  - platform: google

配置我的麦克风,只需要这样添加:

# Host 是 IP, 要看你的设备当前在局域网内是啥 IP
# Media player
media_player:
  - platform: kodi
    name: speaker
    host: 192.168.0.106

文档中还会介绍如何接入小米、Echo等设备,大家可以多多探索。

文档研究高级篇:如何用 script 写稍微复杂的自动化

一般的自动化,我们可以使用 HA 自带的自动化模块进行设计,这里也可以参考文档 官方文档:自动化

配置-自动化-新建自动化,可以直接创建简单的自动化流程
配置-自动化-新建自动化,可以直接创建简单的自动化流程

但在我们这个场景下,自动化流程过于复杂了,所以我们要开始了解如何用编写脚本的方式完成自动化。

  • Shell command 命令行

这个组件,可以把命令行封装成一个服务。命令行可以执行脚本,这样一来,我们就可以执行复杂一点的流程了。而且,更重要的是,我们可以通过这个形式,突破 HA 的沙盒模型,例如导入第三方 Python 包,以实现各种可能性。

命令行相关的组件以及其功能

组件 作用
Shell Command 简单地提供一个 Service,调用之后可以执行输入的命令行
Command Line Binary Sensor 本质上是一个二元传感器(就是说只有On/Off两种状态),根据命令行返回的结果,设置传感器的状态
Command Line Cover 本质上应该是一个类似车库门这样的可以上下左右控制的东西,但没有怎么了解,因为我首先还没有车...
Command Line Notify 本质上是一个消息服务,不过可以使用命令行
Command Line Sensor 本质上是一个传感器,可以通过命令行返回的内容定制各种各样的东西
Command Line Switch 本质上是一个开关,当它开启或者关闭的时候,可以触发不同的命令行

关于 Shell command 的高级用法还可以参考:Home Assistant + 树莓派:强大的智能家居系统 · 高级篇一

这里顺带提一下 Python Scripts 这个组件,它其实和 Shell Command 比较像,就是直接把使用 Python 写的脚本封装成一个可以调用的服务,对于习惯写 Python 的朋友应该稍微有好点。但请注意,这里是在 沙盒环境(sandbox environment) 中,不能直接调用第三方包。

  • Custom component 定制化组件

使用 Custom component 可以按照自己的流程,去定制流程。
以这个项目为例,我将会定制一个叫做 Smart Alarm 的组件,并接入系统,它如果被触发:

  1. 首先,会开启摄像头拍一张照片
  2. 其次,会分析这张照片中,我是否还在床上
  3. 如果是,则让麦克风说话;如果不是,就保持沉默

这样一段流程,用定制化的方式来写,就非常非常简单了。不过,它的缺点也很明显:

  1. 语言是基于 Python 的,对 Python 的要求比较高
  2. 位于沙盒模型中,只能使用 HA 内部的 API

因此,不作赘述,感兴趣的同学可以自己阅读文档:官方文档:自己动手创建一个虚拟组件

文档研究超级复杂篇:什么是沙盒环境,以及脚本如何跨设备联动

这一小节的内容非常 hardcore 和复杂,仅仅是描述下自己踩过的坑,感兴趣的同学可以留心下。在使用 Python 编写脚本的时候,非常重要的一点,是要知道现在是否位于沙盒环境中。这是一种安全策略,在这个环境内,基本上意味着你只能使用 HA 内部定义的 API,不能导入第三方。

组件 环境 局限性 跨设备联动方案
Shell Command(以及上面列出的相关的组件) 无限制,当前 Linux 所在的环境 脚本执行是一次性的,没有什么逻辑判断在里面,无法定义复杂的自动化 利用 HA 对外提供的 REST API 服务
Python Scripts 沙盒环境 只能使用 HA 自己的 API 利用 HA 对内的 API 服务
Custom component 沙盒环境 只能使用 HA 自己的 API 利用 HA 对内的 API 服务

划重点:而在这个智能闹钟项目中,判断当前是否在工作日会需要导入 chinese_calendar 这个包,以及触发照片判断会用到 requests,都一定会使用到第三方包,所以一定要把他们用 Shell Command 封装成两个单独的服务!

# command line sensor,工作日和时间判断
binary_sensor:
  - platform: command_line
    command: 'python3 /home/android/.homeassistant/python_scripts/working_time_check.py'
    name: if_worktime_check
    payload_on: 'Working time'
    payload_off: 'Resting time'

# command line script,触发照片判断
shell_command:
  alarm_check: 'python3 /home/android/.homeassistant/python_scripts/alarm_check.py '

HA 内部 API

该内部方法,可以允许 HA 内沙盒环境内的脚本与 HA 的设备进行交互。

HA 外部 REST API

这个方法,允许 HA 体系外的脚本,能够与 HA 体系内的设备进行交互。但是,这里一定要提前获取令牌,不然请求会失败。实际上,这也是一种安全的措施。你肯定不想自己的设备被其他人入侵。查看官方文档:发出请求前要先授权

首先是授权,获取令牌

点击左上角头像,拉到最底下可以看到长期令牌
点击左上角头像,拉到最底下可以看到长期令牌

请求时,该令牌会需要放置在请求头中,参数名为 Authorization

# 官方样例,这里的 ABCDEFGH 就是令牌内容,Bearer 请保留。创建你个人令牌后,请如法炮制。
import requests 
 url = "https://your.awesome.home/api/error/all" 
headers = {
    'Authorization': "Bearer ABCDEFGH",
} 
response = requests.request('GET', url, headers=headers)

print(response.text)

因为我也是新手,对文档的理解也很浅。所以只能在这里简单分享下我整理的信息,以及常见的几种场景,感兴趣的同学可以再去钻研文档:

HA 内部 API HA 外部 REST API
使用方法 使用 hass 对象 用 requests 的 GET/POST 处理
注意事项 除了 hass 对象以外,还有一堆帮助方法,例如监听某个状态是否有变更 请求头中,要带上提前获取的 Token
文档地址 官方文档:Hass对象入门 官方文档:外部REST API
  1. 获取状态

    • 内部 API:hass.states.get(entity_id)

      # 例如:获取前端设置的时间值
      TIMING = hass.states.get('input_datetime.smart_alarm_timing')
      
    • 外部 REST API:用get请求 http://localhost:8123/api/states/entity_id

      # 例如:获取前端设置的时间值
      headers = {
        'Accept': '*/*',
        'Content-Type': 'application/json;charset=UTF-8',
        'Authorization': 'Bearer 后面接着前面所说的Token',
      }
      response = requests.get('http://localhost:8123/api/states/input_datetime.smart_alarm_timing', headers=headers)
      
  2. 改变状态

    • 内部 API:hass.states.set(entity_id, state)

      # 例如:恢复传感器 am_I_still_in_bed 状态为 'empty'
      hass.states.set('sensor.am_I_still_in_bed', 'empty')
      
    • 外部 REST API:用post带上要设置的状态参数请求 http://localhost:8123/api/states/entity_id

      # 例如:设置传感器 am_I_still_in_bed 状态为 'occupied'
      headers = {
      'Content-Type': 'application/json;charset=UTF-8',
      'Authorization': 'Bearer 后面接着前面所说的Token',
      }
      data = '{"state": "occupied"}'
      response = requests.post(
      'http://localhost:8123/api/states/sensor.am_I_still_in_bed',
      headers=headers,
      data=data)
      

      我还要特别推荐两个官方用例:
      例子一、用 Python 编写虚拟组件
      例子二、有人侵入时触发警报灯

HA 部分代码分享

我还得先想想,这里怎么分享。

感谢

作为面向 Google 编程的选手,我必须要感谢下社区内分享过大量 HA 经验的作者 @墨澜 ,我在文中频繁地引用了她的文章,就是因为她的一系列文章都非常全面,还翻译了 HA 的中文文档。Hats off to her!

下一篇,会围绕项目中另一块硬骨头:视觉识别模型。


欢迎在评论留下你的看法,谢谢大家。

          PHP gets automatically upgraded with ppa:ondrej/php on Ubuntu 16.04 with Moodle 3.5      Cache   Translate Page      
by Robert Andersson.  

Hi, we have a Moodle installation that has been upgraded from 2.7 to 3.1 to 3.5 which we have running on Ubuntu 16.04. For the initial installation we followed the guide at https://docs.moodle.org/en/Step-by-step_Installation_Guide_for_Ubuntu which suggests adding the php7 ppa "ppa:ondrej/php" which we still have.

For some reason it seems like the installed PHP version will get automatically upgraded to the latest PHP major version (like PHP 7.1 to 7.2 to 7.3) when running "apt-get update ; apt-get -y dist-upgrade" even though I can't see what dependency that would cause that.

The problem was that when PHP was upgraded to 7.3 then the Moodle cronjob stopped working because of some PHP parameter incompatibility which caused old data not being removed from the tables "mdl_grade_grades_history" and "mdl_logstore_standard_log" so that those tables started to grow. When changing back the symbolic link /etc/alternatives/php from /usr/bin/php7.3 to /usr/bin/php7.1 the cronjob started to work again. Has anyone else seen this problem or know why PHP gets automatically upgraded to a new major version?

On October 15, 2018, I can see in the log from "apt-get update ; apt-get -y dist-upgrade" that PHP was automatically upgraded to php7.3:

[...]
The following NEW packages will be installed:
libargon2-0 libpcre2-8-0 libphp7.3-embed libsodium23 php7.3-cli php7.3-common php7.3-json php7.3-opcache php7.3-readline
The following packages will be upgraded:
libapache2-mod-php7.1 php-apcu php7.1 php7.1-cli php7.1-common php7.1-curl php7.1-gd php7.1-intl php7.1-json php7.1-mbstring php7.1-mysql php7.1-opcache php7.1-readline php7.1-soap php7.1-xml php7.1-xmlrpc php7.1-zip python-requests python3-requests
19 upgraded, 9 newly installed, 0 to remove and 0 not upgraded.
[...]  

When checking dependencies for all  PHP 7.3 related packages with "apt-cache rdepends" I can't see what dependecy that would case that. Any idea?

          Comment on Learning Enough Python to Land a Job by Phil      Cache   Translate Page      
Hi Peter, Having been a professional coder in Cobol and Delphi from 1998 to 2016, I quit to take a year out, and rather than get into the rather dull world of corporate programming again (I'm 43 now so I've got a longing to do something more meaningful) I decided to try to get into Bioinformatics, helping out with analysis of DNA, finding cures for diseases and so forth. Python seemed like the language of the science world so I chose that. I kicked it off by completing the Python 2 course on codeacademy.com (Python 3 course wasn't available when I started - it is now but it's not free whereas the Python 2 course has always been free). I read the (free) book on Javascript called "Javascript Succinctly" and watched a few youtube videos on HTML and CSS, then put together a program to test vocabulary in foreign languages (I'm trying to learn German). That program uses the Flask framework, so it's Javascript client, Python server. The program is not finished but it is usable. Next up I joined (recently) the codewars website, where you can complete little challenges writing algorithms set by other users. Free too and while some of the instructions on some of the challenges are slightly difficult to understand, once you get into it it's really quite interesting. I live in London so I'm hoping that Bioinformatics will be easy enough to get into (plenty of jobs here apparently) once I'm up to speed with Python (I'm also reading a book on Genomics so that helps me but of course is no use for someone who just wants to learn Python!). There are 3 main documents that I've seen on the official Python website - a Tutorial (which is a nice intro to the basics of Python), a Reference Guide (which is a precise but horrible document to read if you're trying to learn the language, because of the way it's written) and a Library Reference (about 900 pages explaining the built-in libraries available in Python) . All free. I've read the tutorial, about half of the reference guide, and very little of the library reference (I just use this to read about specific topics rather than spending another decade reading the whole thing!). The main thing is to actually start practising programming, and the best way to do that is codeacademy (NB that it IS Python 2!) and codewars (nothing to do with war!). The nice thing about codewars is that after you solve a problem, you are allowed to see how other coders solved the same problem which can be a very useful way of picking up new techniques. There are also some very good tutorials on YouTube for Python. Search for Socratica for example, but there are some others presented by Americans who speak clearly. I say that because there are quite a few videos by people with a strong Indian accent (speaking in English) and while these videos are helpful and often well made, they can be difficult to understand just because of the accent! Good luck with it all !! :-)

          101. Snake. WinForms, GDI+      Cache   Translate Page      
Step-by-step instruction of Snake 2D using C#, WinForms, GDI+ Let's make a very simple classic snake game. For example, if we have a snake head with 10x10 pixels then we will move our snake by a step with 10 pixels using timer. This is the result of our work: Note. I take ideas from this tutorial: Python Snake Game We can set a game field size like this: // Set a game field size ClientSize = new Size(200, 200); Let's create a method for drawing of a rectangle: private void DrawRect(int x, int y, Color color, int size = 10) { Graphics g = CreateGraphics(); SolidBrush brush = new SolidBrush(color); g.FillRectangle(brush, new Rectangle(x, y, size, size)); brush.Dispose(); g.Dispose(); } Each game must have a game loop that will be called by timer. I created the GameLoop method that just prints "Hello, World!" to the debug console every 500 ms: public Form1() { InitializeComponent(); // Set a game field size ClientSize = new Size(200, 200); // Create a timer for the GameLoop method var timer = new Timer(); timer.Tick += GameLoop; timer.Interval = 500; timer.Start(); } private void GameLoop(object sender, System.EventArgs e) { System.Console.WriteLine("Hello, World!"); } For a while our GameLoop will have only two called methods Update() and Draw(). The Update() method will have updates for snake cell coordinates and etc. The Draw() method will have only draw methods for game entities. For example: private void GameLoop(object sender, System.EventArgs e) { Update(); Draw(); } private void Update() { Console.WriteLine("Game entities coords was updated"); } private void Draw() { DrawFood(); DrawSnake(); } private void DrawSnake() { Console.WriteLine("Snake was drawn"); } private void DrawFood() { Console.WriteLine("Food was drawn"); } List data structure is ideal for keeping snake cells coordinates: // Snake list of (x, y) positions private List<Point> _snake = new List<Point>() { new Point(10, 10) }; Point (10, 10) - it is position of the head. It is better to move a general Draw() method call to Form1_Paint() and add Invalidate() call to GameLoop: private void Form1_Paint(object sender, PaintEventArgs e) { Draw(); } private void GameLoop(object sender, System.EventArgs e) { Update(); Invalidate(); } Method for drawing the snake: private void DrawSnake() { foreach (var cell in _snake) { DrawRect(cell.X, cell.Y, Color.Green); } } For moving the snake we need to create the "snakeDir" variable: / Snake movement direction private Point _snakeDir = new Point(10, 0); The snake moving is very simple: you need to add two vectors: the snake head vector position and the snake direction. You add a new vector positions intead of head and remove last element. Please, read comments: private void Update() { // Calc a new position of the head Point newHeadPosition = new Point( _snake[0].X + _snakeDir.X, _snake[0].Y + _snakeDir.Y ); // Insert new position in the beginning of the snake list _snake.Insert(0, newHeadPosition); // Remove the last element _snake.RemoveAt(_snake.Count - 1); } I will explain eating food later. But you can read comments in the code. This is a result code: using System; using System.Collections.Generic; using System.Drawing; using System.Windows.Forms; namespace Snake { public partial class Form1 : Form { // Snake list of (x, y) positions private List<Point> _snake = new List<Point>() { new Point(10, 10) }; // Snake movement direction private Point _snakeDir = new Point(10, 0); // Food private Point _food = new Point(); // Random generator private Random _rnd = new Random(); // Game field size private int _fieldWidth = 200; private int _fieldHeight = 200; // Snake step private int _snakeStep = 10; public Form1() { InitializeComponent(); // Centers the form on the current screen CenterToScreen(); // Set a game field size ClientSize = new Size(_fieldWidth, _fieldHeight); // Generate an initial random position for the food GenerateFood(); // Create a timer for the GameLoop method var timer = new Timer(); timer.Tick += GameLoop; timer.Interval = 200; timer.Start(); } private void Form1_Paint(object sender, PaintEventArgs e) { Draw(); } private void GameLoop(object sender, System.EventArgs e) { Update(); Invalidate(); } private void Update() { // Calc a new position of the head Point newHeadPosition = new Point( _snake[0].X + _snakeDir.X, _snake[0].Y + _snakeDir.Y ); // Insert new position in the beginning of the snake list _snake.Insert(0, newHeadPosition); // Remove the last element _snake.RemoveAt(_snake.Count - 1); // Check collision with the food if (_snake[0].X == _food.X && _snake[0].Y == _food.Y) { // Add new element in the snake _snake.Add(new Point(_food.X, _food.Y)); // Generate a new food position GenerateFood(); } } private void Draw() { DrawFood(); DrawSnake(); } private void DrawSnake() { foreach (var cell in _snake) { DrawRect(cell.X, cell.Y, Color.Green); } } private void DrawFood() { DrawRect(_food.X, _food.Y, Color.OrangeRed); } private void DrawRect(int x, int y, Color color, int size = 10) { Graphics g = CreateGraphics(); SolidBrush brush = new SolidBrush(color); g.FillRectangle(brush, new Rectangle(x, y, size, size)); brush.Dispose(); g.Dispose(); } private void GenerateFood() { _food.X = 10 * _rnd.Next(0, _fieldHeight / 10 - 1); _food.Y = 10 * _rnd.Next(0, _fieldHeight / 10 - 1); } private void Form1_KeyPress(object sender, KeyPressEventArgs e) { switch (e.KeyChar) { case 'w': _snakeDir.X = 0; _snakeDir.Y = -_snakeStep; break; case 'a': _snakeDir.X = -_snakeStep; _snakeDir.Y = 0; break; case 's': _snakeDir.X = 0; _snakeDir.Y = _snakeStep; break; case 'd': _snakeDir.X = _snakeStep; _snakeDir.Y = 0; break; } } } }

I take ideas from this tutorial: Python Snake Game We need to get a canvas context from the canvas element. The canvas context is an object that have methods for working with graphics. Lets' create a script element inside of "index.html" file, get the canvas element, get the canvas context and set a clear color to black: Sandbox !DOCTYPE html> <head> <title>Snake</title> </head> <body> <canvas width="200" height="200" id="gameCanvas"> Your browser does not support HTML5 Canvas.

          Davide Moro: High quality automated docker hub push using Github, TravisCI and pyup for Python tool distributions      Cache   Translate Page      
Let's say you want to distribute a Python tool with docker using known good dependency versions ready to be used by end users... In this article you will see how to continuously keeping up to date a Docker Hub container with minimal managing effort (because I'm a lazy guy) using github, TravisCI and pyup.

The goal was to reduce as much as possible any manual activity for updates, check all works fine before pushing, minimize build times and keep docker container always secure and updated with a final high quality confidence.

As an example let's see what happens under the hood behind every pytest-play Docker Hub update on the official container https://cloud.docker.com/u/davidemoro/repository/docker/davidemoro/pytest-play (by the way if you are a pytest-play user: did you know that you can use Docker for running pytest-play and that there is a docker container ready to be used on Docker Hub? See a complete and working example here https://davidemoro.blogspot.com/2019/02/api-rest-testing-pytest-play-yaml-chuck-norris.html)

Repositories

The docker build/publish stuff lives on another repository, so https://github.com/davidemoro/pytest-play-docker is the repository that implements the Docker releasing workflow for https://github.com/pytest-dev/pytest-play on Docker Hub (https://hub.docker.com/r/davidemoro/pytest-play).

Workflow

This is the highly automated workflow at this time of writing for the pytest-play publishing on Docker Hub:
All tests executions run against the docker build so there is a warranty that what is pushed to Docker Hub works fine (it doesn't check only that the build was successful but it runs integration tests against the docker build), so no versions incompatibilities, no integration issues between all the integrated third party pytest-play plugins and no issues due to the operative system integration (e.g., I recently experienced an issue on alpine linux with a pip install psycopg2-binary that apparently worked fine but if you try to import psycopg2 inside your code you get an unexpected import error due to a recent issue reported here https://github.com/psycopg/psycopg2/issues/684).

So now every time you run a command like the following one (see a complete and working example here https://davidemoro.blogspot.com/2019/02/api-rest-testing-pytest-play-yaml-chuck-norris.html):
docker run --rm -v $(pwd):/src davidemoro/pytest-play
you know what was the workflow for every automated docker push for pytest-play.

Acknowledgements

Many thanks to Andrea Ratto for the 10 minutes travis build speedup due to Docker cache, from ~11 minutes to ~1 minute is a huge improvement indeed! It was possible thanks to the docker pull davidemoro/pytest-play command, the build with the --cache-from davidemoro/pytest-play option and running the longest steps in a separate and cacheable step (e.g., the very very long cassandra-driver compilation moved to requirements_cassandra.txt will be executed only if necessary).

Relevant technical details about pytest-play-docker follows (some minor optimizations are still possible saving in terms of final size).

  • FOSDEM 2019 and Plasma Mobile Sprint

    FOSDEM was fun and inspiring as usual, even if actually getting to see talks has become almost impossible, due to the limit amount of space and the ever growing amount of attendees. However the real value of FOSDEM for me is meeting people anyway, you can’t move a few meters without running into someone you know and want to catch up with.

    Adrian and Agustín have already written about KDE’s presence. My personal highlight was Alistair’s work of bringing Plasma Mobile to RISC-V. Open Source harware and Free Software are a perfect team, and it was also very nice to see our work on bringing KDE components to Yocto being used for this.

  • The Browser Tutorial

    Last week I was invited to give a talk at the first edition of the “Jornadas Tecnológicas Insert Coín” in Coín (Málaga, Spain) to the students of the high school I.E.S. Los Montecillos and other high schools of the area. The subject of the talk was cross-platform development with KDE and Qt. I think the talk was very well received and the students seemed to like it (at least, I think they did). I organized the talk in two sections, first some slides about Qt and KDE (mostly about KDE Frameworks), and then some “live” development to show how use Qt Creator to develop a small web browser with Qt in C++ and then how to use KDevelop to develop the same application in Python.

  • Electron Apps Are Bad, So Now You Can Create Desktop Apps With HTML5 + Golang

    The Electron software framework that allows creating desktop GUI application interfaces using JavaScript and relies upon a bundled Chromium+Node.js run-time is notorious among most Linux desktop users for being resource heavy, not integrating well with most desktops, and generally being despised. For those that are fond of using web standards for creating desktop GUIs, now there is a way to create desktop application front-ends using HTML5 and Golang but with less baggage. 

    Developer Serge Zaitsev presented at FOSDEM 2019 last weekend in Brussels about his work on the Webview and Lorca libraries. These libraries allow building modern desktop applications within the Go programming language while writing the interfaces in HTML5.

  • Return the day in a week with python

    In this example, we are going to develop a method which will receive a number from the user input and returns which day in a week is that numbers refer to. For example, 1 is Sunday and 2 is Monday. If the number is too large or too small then the program will return an error message. Below is the solution to this question, if you have a better solution don’t forget to leave your answer on the below tweet.

  • The Zen of Python
  • Moving iterators in C++

    This will be a short post about a feature in STL that seems to be not as well-known as it should be.

    Imagine we want to create a small function that collects files in the subdirectories of the current directory. So, a list that would be returned by ls */*.

    Note that namespace fs = std::filesystem; is used in the examples.

  • Catching up with the Anaconda distribution

    It's time to catch up with the Anaconda crew and see what's new in the Anaconda distribution. This edition of Python was created to solve some of the stickier problems of deployment, especially in the data science space. Their usage gives them deep insight into how Python is being used in the enterprise space as well. Which turns out to be a very interesting part of the conversation.

  • MPSC Channel API for painless usage of threads with GTK in Rust

    A very common question that comes up on IRC or elsewhere by people trying to use the gtk-rs GTK bindings in Rust is how to modify UI state, or more specifically GTK widgets, from another thread.

    Due to GTK only allowing access to its UI state from the main thread and Rust actually enforcing this, unlike other languages, this is less trivial than one might expect. To make this as painless as possible, while also encouraging a more robust threading architecture based on message-passing instead of shared state, I’ve added some new API to the glib-rs bindings: An MPSC (multi-producer/single-consumer) channel very similar to (and based on) the one in the standard library but integrated with the GLib/GTK main loop.

          FS#61698: [qtile] Doesn't work with python-cairocffi 1.0.0-1      Cache   Translate Page      
Description: Upgrade breaks Qtile Window Manager - unable to login from display manager or console


Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:

When attempting to login from lightdm / webkit greeter or using "exec qtile" from the console, Qtile fails to launch and brings me back to the ligthdm login screen

The best solution for me at the moment is for me to downgrade python-cairocffi to 0.9.0.1

sudo pacman -U python-cairocffi-0.9.0-1-any.pkg.tar.xz

attached is my .xsession-errors.old file which helped me track down the package that was causing the problem.

also, here are two occurrences that happened in the past that were reported on qtile's issue board:

https://github.com/qtile/qtile/issues/680

https://github.com/qtile/qtile/issues/994

This is my first bug report, so hopefully this helps.

The recent release of python-apispec 1.0.0 (from 0.39.0) had at least one breaking change: the web-framework plugins were split to a separate repository, so they aren't installed anymore together with python-apispec. [1][2]

[1] https://github.com/marshmallow-code/apispec/pull/323
[2] https://github.com/marshmallow-code/apispec-webframeworks

For the moment I've published two python-apispec-webframeworks packages on the AUR [3][4], but I was wondering if Felix was interested in just adopting them :) Also I think they should be mentioned as optdepends in python-apispec and python2-apispec.

故事起因

很喜欢网易云音乐,甚至剁手开了年费会员,我这么爱它,所以就很想破解它,控制不住自己,然后就有了这篇文章。

初步探索

寻找目标 URL

我随便找到一首歌,然后打开开发者工具,清空记录,按照下图设置:

图一-打开开发者工具

然后我点击网页的播放按钮,查看输出,等几秒之后,暂停播放,开始检查得到的 URL 及其响应结果,当我看到下图的 URL 时,已经可以确定这个就是我要找的目标 URL 了。

图二-得到目标 URL

寻找目标 JS

和往常一样,我打开 URL 的参数检查,如下图所示。

图三-URL 参数

可以看到此 URL 有一个 csrf_token 查询字符串,以及两个需要 POST 的数据:params 和 encSecKey。

由于平时经常写爬虫,所以我对 URL 的查询字符串异常敏感,我尝试去掉 csrf_token 重新 POST,如图:

图四-重新 POST

发现得到的结果和之前一样,故得出结论 csrf_token 这个东西没有用,我接着看两个 POST 的数据,按照以往的经验,这么长这么重要而且还是 POST,一定是经过 JS 加密的,所以我要找到那个目标 JS,但是假如盲目的寻找肯定找上几个小时也不得行,所以我选择“投机取巧”,直接搜索 表单的 key,搜索 params 得到了很多结果,所以我搜索的是 encSecKey,如图:

图五-搜索 JS

那么现在,我的目标 JS 也找到了

初步分析 JS

我打开 JS ,搜索 encSecKey,跳到图中位置:

图六-打开 JS

显然,我需要的两个参数都和 bUK5P 有关,所以我需要知道 bUK5P 是如何计算得到的,那么所有问题就都解决了,所以我在图六画圈的位置打了一个断点进行调试。

详细的调试技巧各位朋友如果不熟悉请自行谷歌,毕竟我最讨厌那些以干货自居的科普文了。

刷新网页,进入调试界面,点击恢复或者摁下 F8 ,然后一直点跨越或者步进或者 摁 F10/F11,直到当前代码运行位置到达断点之后的语句,如图:

图七-调试_1

然后我进入 console 开始进一步检查,我依次向 console 发送图中的消息,得到的结果如图:

图八-console_1

初步总结

根据以往的经验以及以上的初步分析,我得到以下结论,朋友们也可以认真思索一下:

  1. encSecKey = bUK5P.encSecKey,params = bUK5P.encText
  2. bUK5P 是由 函数 window.asrsea 计算得到的
  3. e5j 是获取歌曲 URL 的详细方式
  4. 函数 window.asrsea 需要 传入四个参数,具体四个参数的分析下面会接触到
  5. 最关键的是function d() 就是 函数 window.asrsea

得到以上结论之后,我开始进行更加深入地探索


深入探索

分析参数

点击 console 的 function d()进入 d 在 JS 中的位置:

图九-function d()

简单浏览函数可以看到:函数 d 调用了 a,b,c 三个函数,a,b,c 的内容如图:

图十-a_b_c

简单阅读代码可以知道:

  • 函数 a 是产生随机的16为字符串
  • 函数 b 是 AES 对称加密过程
  • 函数 c 是 RSA 非对称加密过程

看到这里,我的心里关于网易处理歌曲加载请求的流程已经有了一个大概,卖个关子,继续往下看。

为了详细的探索这四个函数首先我要知道函数 d 的四个参数都是什么,我依旧在图七中的位置打上断点:

  1. 第一次经过断点,各个变量的值如图:

    图十一-values_1

  2. 第二次经过断点,各个变量值如图:

    图十二-values_2

我得到结论:传入函数 d 的四个参数都是常量

分析函数

知道了参数是什么,我开始分析四个函数,我在图示的位置打上断点,至于为什么这么打,请朋友你自行思索:

图十三-调试_3

然后开始调试,经过三个断点,h 的变化情况及各参数的值如图:

图十四-h 变化

好的,调试到这里,我觉得我已经彻底搞清楚这四个函数了,下面我想结合 JS 代码分析一下:

// 函数 a 产生随机 a 位字符串
function a(a) {
    var d,
        e,
        b = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789',
        c = '';
    for (d = 0; a > d; d += 1) e = Math.random() * b.length,
        e = Math.floor(e),
        c += b.charAt(e);
    return c
}
// 函数 b 为 AES 对称加密过程,返回值为加密结果字符串,
// 参数 a:待加密内容,分别为"{\"ids\":\"[32835565]\",\"br\":128000,\"csrf_token\":\"\"}"和 h.encText;
// 参数 b:密钥,长度 16*2=32 bytes,分别为brA7t(['爱心','女孩','惊恐','大笑'])和 i;
function b(a, b) {
    var c = CryptoJS.enc.Utf8.parse(b),
        d = CryptoJS.enc.Utf8.parse('0102030405060708'),
        e = CryptoJS.enc.Utf8.parse(a),
        // c 是key,也就是密钥,长度为32*4=128 bits,所以可知函数 b 加密方式为 AES-128;
        // d 是iv,也就是初始向量;e 是待加密的内容;
        // f 是加密结果;mode 是加密模式为 CBC
        f = CryptoJS.AES.encrypt(e, c, {
            iv: d,
            mode: CryptoJS.mode.CBC
        });
    return f.toString()
}
// 函数 c 为 RSA 非对称加密过程
// 参数 a:16位随机字符串 为 i;
// 参数 b:6位2进制数字 为brA7t(['流泪','强']);
// 参数 c:很长的一串,为brA7t(WU9L.md)
function c(a, b, c) {
    var d,
        e;
    return setMaxDigits(131),
        // c 作为公钥 public_key
        // b 是指数
        d = new RSAKeyPair(b, '', c),
        // a 是待加密的字符串
        e = encryptedString(d, a)
}
// 函数 d 得到 h 结果,即 bUK5P 的结果
// 对照图五及图七可以知道函数 d 的每一个参数都是什么,因为每个参数都是固定的
function d(d, e, f, g) {
    var h = {
    },
        // 调用函数 a 得到参数 i
        // i 的结果为一个16位的随机字符串
        i = a(16);

    // 下面的代码为:两次调用函数 b 得到 encText,一次调用函数 c 得到 encSecKey,最后返回结果 h
    return h.encText = b(d, g),
        // 第一次调用 b
        h.encText = b(h.encText, i),
        // 第二次调用 b
        h.encSecKey = c(i, e, f),
        // 调用 c
        h
}

深入总结

调试了这么久,我就通过猜测网易云音乐处理加载音乐请求的过程来总结一下我得到的所有结论吧:

处理过程

  • 传输的内容经过 AES 和 RSA 两次加密,每次请求随机产生 16 位随机字符串。
  • 首先对歌曲ID等等信息进行两次 AES-128 加密作为 params
    • 第一次常量加密
    • 第二次随机产生 16 位字符串加密
  • 然后对 16 位密钥进行 RSA 加密作为 encSecKey
  • 最后将 encSecKey、params等等传送给服务端
  • 服务端 RSA 解密 encSecKey 得到 16位密钥,再通过密钥解密 params 得到请求信息
  • 服务端返回结果

终极结论

  • 首先随机产生的 16 位密钥是随机的,也是网易控制不了的,所以我相信认真阅读的朋友应该也已经恍然大悟了。
  • 我可以一直使用相同的 16 位字符串,那么 encSecKey 也就成了常量,然后我只需要写一个进行 AES加密的函数就可以了。

Python 实现

加密模块实现

首先我规定密钥为:

ryPnuAVT5RtiIWNi

encSecKey为:

a71973af53caae445b554150da52e75ba5687609d28013aacea03e9ef07169560f156ca76be9ac8df7bb204e05b864756aa3dd2274a65d5be964f118f6d075006695059e10cdcc806306e9a5f2f36f5bf0379f511cd13a600a6cc7031c814583863ea84d3373dea69f74354cd2dc3af61d58eeb43b1de06f588ef361ebc1eed6

然后 Python 实现的 AES-128 加密函数为:

from Crypto.Cipher import AES
import base64
import json
key1 = b'0CoJUm6Qyw8W8jud'
key2 = b'ryPnuAVT5RtiIWNi'
content = {"ids": "[32835565]", "br": 128000, "csrf_token": ""}
encSecKey = 'a71973af53caae445b554150da52e75ba5687609d28013aacea03e9ef07169560f156ca76be9ac8df7bb204e05b864756aa3dd2274a65d5be964f118f6d075006695059e10cdcc806306e9a5f2f36f5bf0379f511cd13a600a6cc7031c814583863ea84d3373dea69f74354cd2dc3af61d58eeb43b1de06f588ef361ebc1eed6'
bs = 16  # block size
# 填充方式为:PKCS5
pad = lambda s: s + (bs - len(s) % bs) * chr(bs - len(s) % bs)
encrypt_token = lambda key, content: AES.new(key=key, mode=AES.MODE_CBC, IV=b'0102030405060708').encrypt(pad(content).encode())
if __name__ == '__main__':
    str_content = json.dumps(content)
    tmp = base64.b64encode(encrypt_token(key1, str_content)).decode()
    params = base64.b64encode(encrypt_token(key2, tmp)).decode()
    print(params)
计算得到的 params 为:
9c3ailRGd3aMtbgRQFsMT6ezDBrVvgP9ENnHgTloTgDKutNCCUxwU8qugl7OFqOY6QumjhXlhqTEV4fp4DeoiMoiMSLZFj0t8pbq7rV8Xt/i/ulXVGvKTaN10KfF8QVs

接下来使用火狐插件 RESTClient 自行 POST 数据进行验证,如图:

图十五-POST

简易接口实现

不多说什么,上完整代码,此代码扩展性很强,记得给我点赞哦~

from Crypto.Cipher import AES
import base64

key2 = b'ryPnuAVT5RtiIWNi'
encSecKey = 'a71973af53caae445b554150da52e75ba5687609d28013aacea03e9ef07169560f156ca76be9ac8df7bb204e05b864756aa3dd2274a65d5be964f118f6d075006695059e10cdcc806306e9a5f2f36f5bf0379f511cd13a600a6cc7031c814583863ea84d3373dea69f74354cd2dc3af61d58eeb43b1de06f588ef361ebc1eed6'

# 加密
pad = lambda s: s + (16 - len(s) % 16) * chr(16 - len(s) % 16)
encrypt_token = lambda key, content: AES.new(key=key, mode=AES.MODE_CBC, IV=b'0102030405060708').encrypt(pad(content).encode())


# 接口
def music_interface(song_id):
    content["ids"] = "[{}]".format(song_id)
    str_content = json.dumps(content)
    tmp = base64.b64encode(encrypt_token(key1, str_content)).decode()
    params = base64.b64encode(encrypt_token(key2, tmp)).decode()
    post_data = {
        'params': params,
        'encSecKey': encSecKey,
    }
    resp = requests.post(url=post_url, headers=headers, data=post_data)
    js = json.loads(resp.content)
    song_url = js['data'][0]['url']
    return song_url


if __name__ == '__main__':
    song_url = music_interface('32835565')
    print(song_url)

后话

最后,我想说一下我的感想。

各位朋友在看到本文之前可能会疑问为什么网易云音乐网页版无法听无损音质的歌,看完之后各位应该了解了,其实这也是网易为了版权保护而采取的下策。

我想,假如非要破解网易云的无损音质下载,那么可能需要逆向网易云音乐的 APK/EXE 构造请求,或者对软件本身进行 Hook 才可以做到吧,等以后有机会有能力我一定会填上这个坑。

生活愉快~

一般问题

为什么要修订 HTTP?

HTTP/1.1 已经在 Web 上服役了十五年以上,但其劣势也开始显现。

加载一个网页比以往更加耗费资源(详见 HTTP Archive’s page size statistics)。与此同时,有效地加载所有这些静态资源变得非常困难,因为事实上,HTTP 只允许每个 TCP 连接有一个未完成的请求。

在过去,浏览器使用多个 TCP 连接来发出并行请求。然而这种做法是有限制的。如果使用了太多的连接,就会产生相反的效果(TCP 拥塞控制将被无效化,导致的用塞事件将会损害性能和网络)。而且从根本上讲这对其他程序来说也是不公平的(因为浏览器会占用许多本不该属于他的资源)。

同时,大量的请求意味着“在线上”有大量重复的数据。

这两个因素都意味着 HTTP/1.1 请求有很多与之相关的开销;如果请求太多,则会影响性能。

这使得业界在有哪些是最好的实践上达成共识,它们包括,比如,Spriting(图片合并)、data: inlining(数据内嵌)、Domain Sharding(域名分片)和 Concatenation(文件合并)等。这些不规范的解决方案说明了协议本身存在一些潜在问题,并且在使用的时候会出现很多问题。

谁制定了 HTTP/2?

HTTP/2 是由 IETF 的 HTTP 工作组开发的,该组织负责维护 HTTP 协议。该组织由众多 HTTP 实现者、用户、网络运营商和 HTTP 专家组成。

值得注意的是,虽然工作组的邮件列表托管在 W3C 网站上,不过这并不是 W3C 的功劳。但是, Tim Berners-Lee 和 W3C TAG与 WG 的进度保持一致。

许多人为这项工作做出了自己的贡献,尤其是一些来自“大”项目的工程师,例如 Firefox、Chrome、Twitter、Microsoft 的 HTTP stack、Curl 和 Akamai。以及若干 Python、Ruby 和 NodeJS 的 HTTP 实现者。

为了更好的了解有关 IETF 的信息,你可以访问 Tao of the IETF;你也可以在 Github 的贡献者图表上查看有哪些人为该项目做出了贡献,同样的,你也可以在 implementation list 上查看谁正在参与该项目。

HTTP/2 与 SPDY 的关系是什么?

HTTP/2 第一次出现并被讨论的时候,SPDY 正得到厂商 (像 Mozilla 和 nginx)的青睐和支持,并被看成是 HTTP/1.x 基础上的重大改善。

在不断的征求建议以及投票选择之后,SPDY/2 被选为 HTTP/2 的基础。从那时起,根据工作组的讨论和用户的反馈,它已经有了很多变化。

在整个过程中,SPDY 的核心开发人员参与了 HTTP/2 的开发,其中包括 Mike Belshe 和 Roberto Peon。

2015 年 2 月,谷歌宣布计划取消对 SPDY 的支持,转而支持 HTTP/2。

究竟是 HTTP/2.0 还是 HTTP/2?

工作组决定删除次要版本(“.0”),因为它在 HTTP/1.x 中造成了很多混乱。也就是说,HTTP 的版本仅代表它的兼容性,不表示它的特性和“亮点”。

和 HTTP/1.x 相比 HTTP/2 的关键区别是什么?

在高版本 HTTP/2 中:

  • 是二进制的,代替原有的文本

  • 是多路复用的,代替原来的序列和阻塞机制

  • 所以可以在一个连接中并行处理

  • 压缩头部信息减小开销

  • 允许服务器主动推送应答到客户端的缓存中

为什么 HTTP/2 是二进制的?

和 HTTP/1.x 这样的文本协议相比,二进制协议解析起来更高效、“线上”更紧凑,更重要的是错误更少。因为它们对如空白字符的处理、大小写、行尾、空链接等的处理很有帮助。

举个栗子 🌰,HTTP/1.1 定义了四种不同的方法来解析一条消息;而在HTTP/2中,仅需一个代码路径即可。

HTTP/2 在 telnet 中不可用,但是我们已经有一些工具可以提供支持,例如 Wireshark plugin。

为什么 HTTP/2 需要多路传输?

HTTP/1.x 有个问题叫“队头阻塞(head-of-line blocking)”,它是指在一次连接(connection)中,只提交一个请求的效率比较高,多了就会变慢。

HTTP/1.1 尝试使用管线化(pipelining)来解决这个问题,但是效果并不理想(对于数据量较大或者速度较慢的响应,依旧会阻碍排在他后面的请求)。此外,由于许多网络媒介(intermediary)和服务器不能很好的支持管线化,导致其部署起来也是困难重重。

这也就迫使客户端使用一些启发式的方法(基本靠猜)来决定通过哪些连接提交哪些请求;由于一个页面加载的数据量,往往比可用连接能处理的数据量的 10 倍还多,对性能产生极大的负面影响,结果经常引起瀑布式阻塞(waterfall of blocked requests)。

而多路传输(Multiplexing)能很好的解决这些问题,因为它能同时处理多个消息的请求和响应;甚至可以在传输过程中将一个消息跟另外一个掺杂在一起。

所以在这种情况下,客户端只需要一个连接就能加载一个页面。

为什么只需要一个 TCP 连接?

如果使用 HTTP/1,浏览器打开每个点(origin)就需要 4 到 8 个连接(Connection)。而现在很多网站都使用多点传输(multiple origins),也就是说,光加载一个网页,打开的连接数量就超过 30 个。

一个应用同时打开这么多连接,已经远远超出了当初设计 TCP 时的预想;同时,因为每个连接都会响应大量的数据,使其可以造成网络缓存溢出的风险,结果可能导致网络堵塞和数据重传。

此外,使用这么多连接还会强占许多网络资源。这些资源都是从那些“遵纪守法”的应用那“偷”的(VoIP 就是个很好的例子)。

服务器推送的好处是什么?

当浏览器请求页面时,服务器发送 HTML 作为响应,然后需要等待浏览器解析 HTML 并发出对所有嵌入资源的请求,然后才能开始发送 JavaScript,图像和 CSS。

服务器推送服务通过“推送”那些它认为客户端将会需要的内容到客户端的缓存中,以此来避免往返的延迟。

但是,推送的响应并不是“万金油”,如果使用不当,可能会损害性能。正确使用服务器推送是一个长期的实验及研究领域。

消息头为何需要压缩?

来自 Mozilla 的 Patrick McManus 通过计算消息头对平均页面负载的印象,对此进行了形象且充分的说明。

假定一个页面有 80 个资源需要加载(这个数量对于今天的 Web 而言还是挺保守的),而每一次请求都有 1400 字节的消息头(这同样也并不少见,因为 Cookie 和引用等东西的存在),至少要 7 到 8 个来回去“在线”获得这些消息头。这还不包括响应时间——那只是从客户端那里获取到它们所花的时间而已。

这全都由于 TCP 的慢启动机制,它根据可以确认的数据包数量对新连接上发送数据的进行限制 — 这有效地限制了最初的几次来回可以发送的数据包数量。

相比之下,即使是头部轻微的压缩也可以是让那些请求只需一个来回就能搞定——有时候甚至一个包就可以了。

这些额外的开销是相当多的,特别是当你考虑对移动客户端的影响的时候。这些往返的延迟,即使在网络状况良好的情况下,也高达数百毫秒。

为什么选择 HPACK?

SPDY/2 提出在每一方都使用一个单独的 GZIP 上下文用于消息头压缩,这实现起来很容易,也很高效。

从那时起,一个重要的攻击方式 CRIME 诞生了,这种方式可以攻击加密文件内部的所使用的压缩流(如GZIP)。

使用 CRIME,那些具备向加密数据流中注入数据能力的攻击者获得了“探测”明文并还原的可能性。因为是 Web,JavaScript 使其成为了可能,而且已经有了通过对受到 TLS 保护的 HTTP 资源的使用CRIME来还原出 cookies 和认证令牌(Toekn)的案例。

因此,我们不应该使用 GZIP 进行压缩。由于找不到其它适合在这种用例下使用的安全有效的算法,所以我们创造了一种新的,针对消息头的,进行粗粒度操作的压缩模式;因为HTTP消息头并不常常需要改变,我们仍然可以得到很好的压缩效率,而且更加的安全。

HTTP/2 可以让 cookies(或者其他消息头)变得更好吗?

这一努力被许可在网络协议的一个修订版本上运行 – 例如,HTTP 消息头、方法等等如何才能在不改变 HTTP 语义的前提下放到“网络上”。

这是因为 HTTP 的应用非常广泛。如果我们使用了这个版本的 HTTP,它就会引入一种新的状态机制(例如之前讨论过的例子)或者改变其核心方法(幸好,这还没有发生过),这可能就意味着新的协议将不会兼容现有的 Web 内容。

具体地,我们是想要能够从 HTTP/1 转移到 HTTP/2,并且不会有信息的丢失。如果我们开始”清理”消息头(大多数人都认为现在的 HTTP 消息头简直是一团糟),我们就不得不去面对现有 Web 的诸多问题。

这样做只会对新协议的普及造成麻烦。

总而言之,工作组 会对所有的 HTTP 负责,而不仅仅只是 HTTP/2。因此,我们才可以在版本独立的新机制下运作,只要它们也能同现有的网络向下兼容。

非浏览器用户的 HTTP 是什么样的?

如果非浏览器应用已经使用过 HTTP 的话,那他们也应该可以使用 HTTP/2。

先前收到过 HTTP “APIs” 在 HTTP/2 中具有良好性能等特点这样的反馈,那是因为 API 的设计不需要考虑类似请求开销这样一些事情。

话虽如此,我们正在考虑的改进重点是典型的浏览用例,因为这是协议主要的使用场景。

我们的章程里面是这样说的:

正在组织的规范需要满足现在已经普遍部署了的 HTTP 的功能要求;具体来说主要包括,Web 浏览(桌面端和移动端),非浏览器(“HTTP APIs” 形式的),Web 服务(大范围的),还有各种网络中介(借助代理,企业防火墙,反向代理以及内容分发网络实现的)。同样的,对 HTTP/1.x 当前和未来的语义扩展 (例如,消息头,方法,状态码,缓存指令) 都应该在新的协议中支持。

值得注意的是,这里没有包括将 HTTP 用于非特定行为所依赖的场景中(例如超时,连接状态以及拦截代理)。这些可能并不会被最终的产品启用。

HTTP/2 需要加密吗?

不需要。在激烈的讨论后,工作组没有就新协议是否使用加密(如 TLS)而达成共识。

不过,有些观点认为只有在加密连接上使用时才会支持 HTTP/2,而目前还没有浏览器支持未加密的 HTTP/2。

HTTP/2 是怎么提高安全性的呢?

HTTP/2 定义了所需的 TLS 文档,包括版本,密码套件黑名单和使用的扩展。

细节详见相关规范。

还有对于一些额外机制的讨论,例如对 HTTP:// URLs(所谓的“机会主义加密”)使用 TLS;详见 RFC 8164。

我现在可以使用 HTTP/2 吗?

浏览器中,最新版本的 Edge、Safari、Firefox 和 Chrome都支持 HTTP/2。其他基于 Blink 的浏览器也将支持HTTP/2(例如 Opera 和 Yandex 浏览器)。详见 caniuse。

还有几个可用的服务器(包括来自 Akamai,Google 和 Twitter 的主要站点的 beta 支持),以及许多可以部署和测试的开源实现。

有关详细信息,请参阅实现列表。

HTTP/2 将会取代 HTTP/1.x 吗?

工作组的目的是让那些使用 HTTP/1.x 的人也可以使用 HTTP/2,并能获得 HTTP/2 所带来的好处。他们说过,由于人们部署代理和服务器的方式不同,我们不能强迫整个世界进行迁移,所以 HTTP/1.x 仍有可能要使用了一段时间。

HTTP/3 会出现吗?

如果通过 HTTP/2 引入的沟通协作机制运行良好,支持新版本的 HTTP 就会比过去更加容易。

实现过程中的问题

为什么规则会围绕消息头帧的数据接续?

数据接续的存在是由于一个值(例如 cookie)可以超过 16kb,这意味着它不可能全部装进一个帧里面。

所以就决定以最不容易出错的方式让所有的消息头数据以一个接一个帧的方式传递,这样就使得对消息头的解码和缓冲区的管理变得更加容易。

HPACK 状态的最小和最大尺寸是多少?

接收一方总是会控制 HPACK 中内存的使用量, 并且最小能设置到 0,最大则要看 SETTING 帧中能表示的最大整型数是多少,目前是 2^32 - 1。

我怎样才能避免保持 HPACK 状态?

发送一个 SETTINGS 帧,将状态尺寸(SETTINGSHEADERTABLE_SIZE)设置到 0,然后 RST 所有的流,直到一个带有 ACT 设置位的 SETTINGS 帧被接收。

为什么会有一个单独的压缩/流程控制上下文?

简单说一下。

原来的提案里面提到了流分组这个概念,它可以共享上下文,进行流控制等等。尽管那样有利于代理(也有利于用户体验),但是这样做相应也会增加一点复杂度。所以我们就决定先以一个简单的东西开始,看看它会有多糟糕的问题,并且在未来的协议版本中解决这些问题(如果有的话)。

为什么在 HPACK 中有 EOS 的符号?

由于 CPU 效率和安全的原因,HPACK 的霍夫曼编码填充了霍夫曼编码字符串的下一个字节边界。因此对于任何特定的字符串可能需要 0-7 个比特的填充。

如果单独考虑霍夫曼解码,任何比所需要的填充长的符号都可以正常工作。但是,HPACK 的设计允许按字节对比霍夫曼编码的字符串。通过填充 EOS 符号需要的比特,我们确保用户在做霍夫曼编码字符串字节级比较时是相等的。反之,许多 headers 可以在不需要霍夫曼解码的情况下被解析。

实现 HTTP/2 的时候我可以不用去实现 HTTP/1.1 吗?

通常/大部分时候可以。

对于运行在 TLS(h2)之上的 HTTP/2 而言,如果你没有实现http1.1的 ALPN 标识,那你就不需要支持任何 HTTP/1.1 的特性。

对于运行在 TCP(h2c)之上的 HTTP/2 而言,你需要实现最初始的升级(Upgrade)请求。

只支持h2c的客户端需要生成一个针对 OPTIONS 的请求,因为“*”或者一个针对 “/” 的 HEAD 请求,他们相当安全,并且也很容易构建。仅仅只希望实现 HTTP/2 的客户端应当把没有带上 101 状态码的 HTTP/1.1 响应看做错误处理。

只支持h2c的服务器可以使用一个固定的 101 响应来接收一个包含升级(Upgrade)消息头字段的请求。没有h2c的升级令牌的请求可以使用一个包含了 Upgrade 消息头字段的 505(HTTP 版本不支持)状态码来拒绝。那些不希望处理 HTTP/1.1 响应的服务器应该在发送了带有鼓励用户在升级了的 HTTP/2 连接上重试的连接序言之后立即用带有 REFUSED_STREAM 错误码拒绝该请求的第一份数据流.

5.3.2节中的优先级示例是否正确?

不,那是正确的。流 B 的权重为 4,流 C 的权重为 12。为了确定每个流接收的可用资源的比例,将所有权重(16)相加并将每个流权重除以总权重。因此,流 B 接收四分之一的可用资源,流 C 接收四分之三。因此,正如规范所述:流 B 理想地接收分配给流 C 的资源的三分之一。

HTTP/2 连接中需要 TCP_NODELAY 吗?

是的,有可能。即使对于仅使用单个流下载大量数据的客户端,仍然需要一些数据包以相反的方向发回以实现最大传输速度。在没有设置 TCP_NODELAY(仍然允许 Nagle 算法)的情况下,可以传输的数据包将被延迟一段时间以允许它们与后续分组合并。

例如,如果这样一个数据包告诉对等端有更多可用的窗口来发送数据,那么将其发送延迟数毫秒(或更长时间)会对高速连接造成严重影响。

部署问题

我该怎么调试加密过的 HTTP/2?

存取应用程序数据的方法很多,最简单的方法是使用 NSS keylogging 配上 Wireshark 插件(包含在最新开发版中)。这种方法对 Firefox 和 Chrome 都适用。

我该怎么使用 HTTP/2 的服务端推送?

HTTP/2 服务器推送允许服务器向客户端提供内容而无需等待请求。这可以提高检索资源的时间,特别是对于具有大带宽延迟产品的连接,其中网络往返时间占了在资源上花费的大部分时间。

推送基于请求内容而变化的资源可能是不明智的。目前,浏览器只会推送请求,如果他们不这样做,就会提出匹配的请求(详见 Section 4 of RFC 7234)。

有些缓存不考虑所有请求头字段的变化,即使它们列在Varyheader 字段中。为了使推送资源被接收的可能性最大化,内容协商是最好的选择。基于accept-encoding报头字段的内容协商受到缓存的广泛尊重,但是其他报头字段可能不受支持。

Hey @briend!

Thanks for the update! I had it installed and the rotation works well!

I think I broke it :sweat_smile:#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000 I was trying to adjust some smudge settings when it crashed, then when I started up mypaint again the rotation correction stopped working.
Might just be me but I feel the smudge attribute seems to be weaker when it was working for some reason?

I tried deleting settings in Appdata/Local and reinstalling brushes but that didn’t work.

I also got a bug detection log

          10 лучших автомобилей-амфибий      Cache   Translate Page      

Автомобили-амфибии - весьма специфические представители автопрома. Эти автомобили позволяют с одинаковым успехом передвигаться как по дорогам, там и по водной глади. В этом обзоре речь пойдет о наиболее популярных и качественных образчиках такого транспорта, созданных в нынешнем и прошлом веке.

1. VW Type 166

Научно-технический прогресс традиционно стимулируется двумя вещами – кризисом чего-либо и войной. Откровенно говоря, ничто так не двигает науку, как война. Вот и во время Второй мировой войны мир получил просто невероятно количество самых необычных образцов техники. Одним из таких стала машина-амфибия VW Type 166.

2. Gibbs Aquada

Автомобили семейства Gibbs Aquada почти все амфибии. Выпускаются в нескольких модификациях. Есть, в том числе и амфибия-внедорожник. В конце 90-х годов прошлого столетия на Gibbs Aquada был установлен абсолютный рекорд по скорости движения по воде среди автомобилей данного класса. Пилотировал машину Ричард Брэнсон. Стоит также отметить, что Gibbs Aquada разрабатывалась главным образом для нужно полиции и спасателей.

3. Bond’s Lotus Esprit

Концептуальный автомобиль Bond’s Lotus Esprit появился уже достаточно давно. Единственно, что существенно отличает его от всех других автомобилей данного класса, так это возможность превращения в полноценную подводную лодку, пускай и с небольшой глубиной погружения.

4. Amphicar

Даже сегодня старичок Amphicar остается одной из лучших амфибий. Все дело в том, что этот малоприглядный автомобиль обеспечивает лучшую проходимость по водной глади, благодаря особенностям формы кузова и невероятной мощности двигателя. Рассчитан он правда, всего на двух человек.

5. Ferrari Barchetta

Именно так, Ferrari также пытались создавать амфибии. Наглядным примером тому является модель Barchetta. Первый подобный автомобиль был сконструирован инженерами широко известного бренда еще в середине прошлого столетия. Последний образец, на сегодняшний день, выпускался в 90-е годы XX века.

6. Wooden F50

Самая необычная амфибия – это Wooden F50. Как можно увидеть на фото, машина почти полностью сделана из дева. Что же касается характеристик, то плавает она действительно очень неплохо, как впрочем, и любое другое бревно, попавшее в воду.

7. Dutton Surf

Автомобиль-амфибия Dutton Surf никогда не был серийным, хотя бы, потому что является уникальной кустарной моделью. Создан он был на базе автомобиля марки Suzuki. За такую модификацию конструктор-энтузиаст по некоторым данным чуть не угодил в тюрьму. Худшего не произошло, но машины он больше не модифицирует.

8. Watercar Python

Амфибия Watercar Python на сегодняшний день является одной из самых быстрых. Более того, это одна из немногих моделей, у которой есть допуск к плаванью в открытом море. На воде кабриолет развивает просто потрясающую скорость.

9. Buick Riviera

Сложно поверить, однако Buick Riviera – тоже автомобиль-амфибия. Несмотря на солидный возраст, машина может похвастаться неплохими ездовыми и плавательными качествами. Более того, ее можно использовать для морских прогулок.

10. Rinspeed Splash

А вот самая, самая необычная амфибия. В отличие от большинства других машин подобного типа, Rinspeed Splash использует специальные выдвижные лыжи для скольжения по воде. Создан автомобиль был еще в 2004 году.

Оказывается, плавать умеют не только автомобили, но и жилые здания. Например, такие, как дома-амфибии, которым не страшен никакой паводок.

          Comment on On Secretly Terrible Engineers by David Behat      Cache   Translate Page      
I think that unfortunately bad engineers are the dominant force. Going through dozens of different job specifications it’s clear to me that 95% aren’t making architectural decisions but treating software engineering and programming almost like it’s an acting job. The tell tale signs of this are two things, the following of trends and excessive complexity. There are two forces at play here. The first is people hopping on the bandwagon. Today there are a host of popular methodologies and technologies that are widely adopted. You have to ask yourself however what did people do before docker, CI/CD, Scrum/XP, TDD/BDD/DDD, NoSQL, the cloud, distributed, frameworks, eventual consistency, blockchain, event sourcing, command bus, CQRS, etc. Don’t get me wrong, all of these things have their place and I enjoy utilising them when I have a suitable problem for these solutions. It’s very different however when suddenly 90% or more of places are suddenly using those without real need. Few of those things could be considers 90% applicable or useful. You very quickly realise that the decision making process is simple, use whatever you’ve heard a lot about recently. I’ve seen this cause plenty of engineering projects for a very simple reason. It over complicates things. It’s overkill. Solutions are also complemented by their problems. Using any solution without a real purpose it extremely difficult for any efficient and purposeful programmer that isn’t simply a mindless drone. Order a robot to go to the shops but in the walking style of the Monty Python Ministry of Silly Walks sketch then it’ll do so but if you ask a human to do that you would expect resistance which is appropriate. You often see developers struggle so hard trying to master these silly walks they never actually get to their destination in the first place. Ditch the walk and get to the destination you get sacked. Ditch the destination and focus on getting the walk right then you receive a pat on the back in the next sprint meeting for having made a fabulous effort at the silly walk. It becomes even more insidious as this becomes a defence to keep out any developers, good or bad. A founding developer masters a ridiculously complex technique and then insists that’s how things must be done even though that technique may not only be completely unnecessary but most likely counter productive. This creates a process of learning knowledge and then applying it in a hostile fashion as anti-competition. If people can’t pull their weight that’s a problem. Programming isn’t necessarily something you can easily apply to parallel work such as rowing. Different programmers cover very different bases and sometimes it’s not possible to exceed the output of a single developer that’s really good by combining the efforts of any ten developers of arbitrary ability. I will however use the rowing analogy. If you’ve ever been on a rowing team you know you have your own ore and you have to be able to manage that. If someone needs to help you with your ore, you’re almost certainly not cut out for it. What we see in programming it a bit more like you have to also to use a most ridiculous rowing style or everyone most row with only one hand and essentially nonsense that doesn’t get the boat moving faster, instead it simply makes the job harder. I’d urge caution in your approach. Not that many people really are wired for engineering logic, nor smart and not necessarily eager to learn either. Dunning Kruger and arrogance are two very serious problems in the field. You shouldn’t reinforce that. What you want is people who are willing to do the job and willing to learn what they need to in order to do that. You want people who are also humble. You never want people who think they’re smart, a hotshot, etc except perhaps in the rare situation where people may have actually earned their confidence. That’s not something easily discerned. I understand your point but you should be very careful in proposing problems for an industry you don’t fully understand. It’s like playing chess when you don’t fully understand. You see the problem of your piece being threatened by the enemy bishop so you move it away. Then a pawn takes your piece because you didn’t know pawns could attack at an angle. Where you hit the mark is that people should appreciate that developers can learn and look for transferable skills. People should also be reasonable in the make up of their team. In reality there’s only around one in five to one in ten natural born developers, a team wont be off equals. It’s also generally better to have a few dogbodies or stratified as not only does it cause less friction or headbutting but it also means that you have people naturally more satisfied with covering more bases. There’s often plenty an idiot can do and they won’t like doing all the hard or complex things the smart person does. They will however be quite happy doing a lot of the less intellectually stimulating work. There’s definitely a problem with almost every job spec demanding intimate experience in the exact tech stack they’ve chosen. I almost went into something else as well when I started out and that was one of the reasons. I was lucky enough to find an area of programming less contrived however my preferred niche is now also becoming outrageously contrived. There’s a lot of scope for frustration and hostility if you can actually program. I did tens of thousands of lines of code in high school, I had learnt to be fluent in different types of languages, had programmed by own webservers, games, etc. I too then went and got a CS degree. Increasingly most people don’t have that background, instead they come from a purely academic background. That’s been around now for over a decade and has continually grown as a pervasive force. You have a lot of people arrogant after memorising things and learning things academically, passing tests, etc but in reality they’re very poorly practised and lack the experience to make good tech decisions. In many cases they can’t really program at all or all they can do it repeat what they studied. That creates a huge culture of pseudo-intellectual academic elitism. That form of elitism works well in academia but is not an effective replacement for professionalism. It started with Java which made a significant effort to gain ground academically and has since spread further and further.

          When I was sleepy      Cache   Translate Page      

Back in 2005 I joined my first job, in a software company in Bangalore. It was a backend of a big foreign bank. We trained heavily on different parts of software development during the first few months. At the same time, I had an altercation with the senior manager (about some Java code) who was in charge of the new joinees and their placement within the company. The result? Everyone else got a team but me, and I had to roam around within the office to find an empty seat and wait there till the actual seat owner came back. I managed to spend a lot of days in the cafeteria on the rooftop. But, then they made new rules that one can not sit there either, other than at lunch time.

So, I went asking around, talking to all the different people in the office (there were 500+ folks iirc) if they know any team who would take on a fresher. I tried to throw in words like Linux, open source to better my chances. And then one day, I heard that the research and development team was looking for someone with Linux and PHP skills. I went in to have a chat with the team, and they told me the problem (it was actually on DSpace, a Java based documentation/content repository system), and after looking at my resume decided to give me a desktop for couple of weeks. I managed to solve the problem in next few days, and after a week or so, I was told that I will join the team. There were couple of super senior managers and I was the only kid on that block. Being part of this team allowed me to explore different technologies and programming languages.

I will later write down my experiences in more detail, but for today, I want to focus on one particular incident. The kind of incident, which all system administrators experience at least once in their life (I guess). I got root access to the production server of the DSpace installation within a few weeks. I had a Windows desktop, and used putty to ssh in to the server. As this company was backend of the big bank, except for a few senior managers, no one else had access to Internet on their systems. There were 2 desktops in the kiosk in the ground floor, and one had to stand in a long queue to get a chance to access Internet.

One day I came back from the lunch (a good one), and was feeling a bit sleepy. I had taken down the tomcat server, pushed the changes to the application, and then wanted to start the server up again. Typed the whole path to startup.sh (I don’t remember the actual name, I’m just guessing it was startup.sh) and hit Enter. I was waiting for the long screens of messages this startup script spewed as it started up, but instead, I got back the prompt quickly. I was wondering what went wrong. Then, looking at the monitor very closely, I suddenly realised that I was planning to delete some other file and I had written rm at the beginning of the command prompt, forgotten it, and then typed the path of the startup.sh. Suddenly I felt the place get very hot and stuffy; I started sweating and all blood drained from my face in the next few moments. I was at panic level 9. I was wondering what to do. I thought about the next steps to follow. I still had a small window of time to fix the service. Suddenly I realized that I can get a copy of the script from the Internet (yay, Open Source!). So, I picked up a pad and a pen, ran down to the ground floor, and stood in the queue to get access to a computer with Internet. After getting the seat, I started writing down the whole startup.sh on the pad and double checked it. Ran right back up to my cubicle, feverishly typed in the script, (somehow miraculously without any typo in one go.) As I executed the script, I saw the familiar output, messages scrolling up, screen after joyful screen. And finally as it started up, I sighed a huge sigh of relief. And after the adrenalin levels came down, I wrote an incident report to my management, and later talked about it during a meeting.

From that day on, before doing any kind of destructive operation, I double check the command prompt for any typo. I make sure, that I don’t remove anything randomly and also make sure that I have my backups is place.

          Przemysław Kołodziejczyk: Python 3 - Template strings instead of external template engine      Cache   Translate Page      
I don’t know about you, but there is only one thing where I use templates on the backend side. Emails. Usually, when people need to render HTML template, they install Jinja2 or other template engines. The case is that it’s not always required. If you have a template where you need to put some data, you don’t need an external template engine. When you need to do something with this data, you don’t need to do that inside a template using Jinja2 filters.

What’s pyenv? pyenv lets you easily switch between multiple versions of Python It’s like nvm but for Python ;-) Install pyenv. brew install pyenv How to use it?

My snake hasn't been eating the past month, which isn't too worrying or abnormal for ball pythons. I tried switching to a live feed yesterday to see if it'll catch her interest but she wouldn't eat the mouse, and the mouse was just kinda chill around the snake. Since my snake wouldn't eat it and I couldn't bring myself to kill it to save for later- I now have a pet mouse I guess.

His name is Jean Luc and he likes to chill and watch movies at my desk.
          I need a new computer, what look for?      Cache   Translate Page      
What is up my, bitches? Long time lurker here to ask you magnificent bastards about computers.

So, getting right down to business, I need a strong laptop that can run 3D modeling and simulation software for my lab work. So, obviously a strong core and good amount of RAM are pretty necessary. The issue is, aside from those two things, I have no freaking idea what to look for. I would like to be able to do some minor gaming on the computer, but it's more of a work laptop I want.

What do you say FJ? Wanna explain computers to me and save me from the blood suckers at best-buy?


*EDIT
Hey, I just want to thank all of you guys for taking the time to give me a bit of advice

For those asking, the budget is give or take a grand and I mostly work with Solidworks, some AutoCAD, a lot of Lab View and a lot of python there are other miscelanious little things I work with too, but those are the big ones

Also, I can go the route of a desktop, but a laptop allows me to work from the office.

"Twardy brexit możliwy, więc Heathrow gromadzi gumowe rękawiczki"

Lotnisko Heathrow robi zapasy gumowych rękawiczek sprowadzanych z UE, aby mieć pewność, że w przypadku tzw. twardego brexitu na lotnisku będzie można bez problemu nadal dokonywać kontroli osobistych pasażerów.

Na lotnisku Heathrow codziennie odprawia się ok. 200 tys. pasażerów. Dyrekcja lotniska przyznaje, że niektóre produkty wykorzystywane do kontroli - takie jak rękawiczki - nie są produkowane w Wielkiej Brytanii i muszą być sprowadzane z UE. A w przypadku twardego brexitu, do czasu zawarcia porozumień z Unią Europejską regulujących wymianę handlową, ich import nie będzie możliwy.

Również patyczki wykorzystywane np. do szukania śladów materiałów wybuchowych lotnisko sprowadza z UE, a tymczasem w Wielkiej Brytanii nie ma dostawców ani gumowych rękawic potrzebnych na lotnisku.

When I try to launch Sigil from the menu in the GUI nothing happens. So I try in CLI and get the following, after which nothing happens Code: --------- ron@localhost:~/ $ sigil Warning: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-ron' Warning: Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed Warning: libpng warning: iCCP: known incorrect sRGB profile Warning: libpng warning: iCCP: known incorrect sRGB profile --------- So I try Ctrl-C and get Code: --------- ^CPlease close browser and run mozplugger-update --------- followed by an error message window "Embedded Python Error" followed by another one "error in XMLprocessor repairXML -5"; after which Sigil starts. The second message about mozplugger-update is interesting, since I do not have mozplugger-update on my system although the Mozplugger package is installed. Any idea where I should start digging ?
