MySQL is an excellent database for advanced analytics, but few analysts use it that way because they aren't fully aware of its capabilities in this area. Analysts end up writing code to perform common tasks—which can be time-consuming—rather than using MySQL to do the same work. In this course, learn tips and techniques for using MySQL for advanced data analytics. Kumaran Ponnambalam walks through the different stages of analytics, from data ingestion and transformation to generating statistics. In each stage, Kumaran focuses on letting MySQL do the heavy lifting rather than writing code in Java or Python. Discover how to perform data cleansing through MySQL update commands, find peak usage of any resource, perform centering and scaling of data to prepare for machine learning, and more. Plus, Kumaran shows how you can link MySQL with Microsoft Excel to get the best of both worlds.

          Kay Hayen: Nuitka Release 0.5.31      Cache   Translate Page   Web Page Cache   

This is to inform you about the new stable release of Nuitka. It is the extremely compatible Python compiler. Please see the page "What is Nuitka?" for an overview.

This release is massive in terms of fixes, but also adds a lot of refinement to code generation, and more importantly adds experimental support for Python 3.7, while enhancing support for Pyt5 in standalone mode by a lot.

Bug Fixes

  • Standalone: Added missing dependencies for PyQt5.Qt module.

  • Plugins: Added support for PyQt5.Qt module and its qml plugins.

  • Plugins: The sensible plugin list for PyQt now includes that platforms plugins on Windows too, as they are kind of mandatory.

  • Python3: Fix, for uninstalled Python versions wheels that linked against the Python3 library as opposed to Python3X, it was not found.

  • Standalone: Prefer DLLs used by main program binary over ones used by wheels.

  • Standalone: For DLLs added by Nuitka plugins, add the package directory to the search path for dependencies where they might live.

  • Fix, the vars built-in didn't annotate its exception exit.

  • Python3: Fix, the bytes and complex built-ins needs to be treated as a slot too.

  • Fix, consider if del variable must be assigned, in which case no exception exit should be created. This prevented Tkinter compilation.

  • Python3.6: Added support for the following language construct:

    d = {"metaclass" : M}
    
    class C(**d):
       pass
    
  • Python3.5: Added support for cyclic imports. Now a from import with a name can really cause an import to happen, not just a module attribute lookup.

  • Fix, hasattr was never raising exceptions.

  • Fix, bytearray constant values were considered to be non-iterable.

  • Python3.6: Fix, now it is possible to del __annotations__ in a class and behave compatible. Previously in this case we were falling back to the module variable for annotations used after that which is wrong.

  • Fix, some built-in type coversions are allowed to return derived types, but Nuitka assumed the excact type, this affected bytes, int, long, unicode.

  • Standalone: Fix, the _socket module was insisted on to be found, but can be compiled in.

New Features

  • Added experimental support for Python 3.7, more work will be needed though for full support. Basic tests are working, but there are are at least more coroutine changes to follow.
  • Added support for building extension modules against statically linked Python. This aims at supporting manylinux containers, which are supposed to be used for creating widely usable binary wheels for Linux. Programs won't work with statically linked Python though.
  • Added options to allow ignoring the Windows cache for DLL dependencies or force an update.
  • Allow passing options from distutils to Nuitka compilation via setup options.
  • Added option to disable the DLL dependency cache on Windows as it may become wrong after installing new software.
  • Added experimental ability to provide extra options for Nuitka to setuptools.
  • Python3: Remove frame preservation and restoration of exceptions. This is not needed, but leaked over from Python2 code.

Optimization

  • Apply value tracing to local dict variables too, enhancing the optimization for class bodies and function with exec statements by a lot.
  • Better optimization for "must not have value", wasn't considering merge traces of uninitialized values, for which this is also the case.
  • Use 10% less memory at compile time due to specialized base classes for statements with a single child only allowing __slots__ usage by not having multiple inheritance for those.
  • More immediately optimize branches with known truth values, so that merges are avoided and do not prevent trace based optimization before the pass after the next one. In some cases, optimization based on traces could fail to be done if there was no next pass caused by other things.
  • Much faster handling for functions with a lot of eval and exec calls.
  • Static optimization of type with known type shapes, the value is predicted at compile time.
  • Optimize containers for all compile time constants into constant nodes. This also enables further compile time checks using them, e.g. with isinstance or in checks.
  • Standalone: Using threads when determining DLL dependencies. This will speed up the un-cached case on Windows by a fair bit.
  • Also remove unused assignments for mutable constant values.
  • Python3: Also optimize calls to bytes built-in, this was so far not done.
  • Statically optimize iteration over constant values that are not iterable into errors.
  • Removed Fortran, Java, LaTex, PDF, etc. stuff from the inline copies of Scons for faster startup and leaner code. Also updated to 3.0.1 which is no important difference over 3.0.0 for Nuitka however.
  • Make sure to always release temporary objects before checking for error exits. When done the other way around, more C code than necessary will be created, releasing them in both normal case and error case after the check.
  • Also remove unused assignments in case the value is a mutable constant.

Cleanups

  • Don't store "version" numbers of variable traces for code generation, instead directly use the references to the value traces instead, avoiding later lookups.
  • Added dedicated module for complex built-in nodes.
  • Moved C helpers for integer and complex types to dedicated files, solving the TODOs around them.
  • Removed some Python 3.2 only codes.

Organizational

  • For better bug reports, the --version output now contains also the Python version information and the binary path being used.
  • Started using specialized exceptions for some types of errors, which will output the involved data for better debugging without having to reproduce anything. This does e.g. output XML dumps of problematic nodes.
  • When encountering a problem (compiler crash) in optimization, output the source code line that is causing the issue.
  • Added support for Fedora 28 RPM builds.
  • Remove more instances of mentions of 3.2 as supported or usable.
  • Renovated the graphing code and made it more useful.

Summary

This release marks important progress, as the locals dictionary tracing is a huge step ahead in terms of correctness and proper optimization. The actual resulting dictionary is not yet optimized, but that ought to follow soon now.

The initial support of 3.7 is important. Right now it apparently works pretty well as a 3.6 replacement already, but definitely a lot more work will be needed to fully catch up.

For standalone, this accumulated a lot of improvements related to the plugin side of Nuitka. Thanks to those involved in making this better. On Windows things ought to be much faster now, due to parallel usage of dependency walker.

          How ProPublica Illinois Uses GNU Make to Load 1.4GB of Data Every Day      Cache   Translate Page   Web Page Cache   

I avoided using GNU Make in my data journalism work for a long time, partly because the documentation was so obtuse that I couldn’t see how Make, one of many extract-transform-load (ETL) processes, could help my day-to-day data reporting. But this year, to build The Money Game, I needed to load 1.4GB of Illinois political contribution and spending data every day, and the ETL process was taking hours, so I gave Make another chance.

Now the same process takes less than 30 minutes.

Here’s how it all works, but if you want to skip directly to the code, we’ve open-sourced it here.

Fundamentally, Make lets you say:

  • File X depends on a transformation applied to file Y
  • If file X doesn’t exist, apply that transformation to file Y and make file X

This “start with file Y to get file X” pattern is a daily reality of data journalism, and using Make to load political contribution and spending data was a great use case. The data is fairly large, accessed via a slow FTP server, has a quirky format, has just enough integrity issues to keep things interesting, and needs to be compatible with a legacy codebase. To tackle it, I needed to start from the beginning.

Overview

The financial disclosure data we’re using is from the Illinois State Board of Elections, but the Illinois Sunshine project had released open source code (no longer available) to handle the ETL process and fundraising calculations. Using their code, the ETL process took about two hours to run on robust hardware and over five hours on our servers, where it would sometimes fail for reasons I never quite understood. I needed it to work better and work faster.

The process looks like this:

  • Download data files via FTP from Illinois State Board Of Elections.
  • Clean the data using Python to resolve integrity issues and create clean versions of the data files.
  • Load the clean data into PostgreSQL using its highly efficient but finicky “\copy” command.
  • Transform the data in the database to clean up column names and provide more immediately useful forms of the data using “raw” and “public” PostgreSQL schemas and materialized views (essentially persistently cached versions of standard SQL views).

The cleaning step must happen before any data is loaded into the database, so we can take advantage of PostgreSQL’s efficient import tools. If a single row has a string in a column where it’s expecting an integer, the whole operation fails.

GNU Make is well-suited to this task. Make’s model is built around describing the output files your ETL process should produce and the operations required to go from a set of original source files to a set of output files.

As with any ETL process, the goal is to preserve your original data, keep operations atomic and provide a simple and repeatable process that can be run over and over.

Let’s examine a few of the steps:

Download and Pre-import Cleaning

Take a look at this snippet, which could be a standalone Makefile:

data/download/%.txt :
aria2c -x5 -q -d data/download --ftp-user="$(ILCAMPAIGNCASH_FTP_USER)" --ftp-passwd="$(ILCAMPAIGNCASH_FTP_PASSWD)" 
ftp://ftp.elections.il.gov/CampDisclDataFiles/$*.txt

data/processed/%.csv : data/download/%.txt
python processors/clean_isboe_tsv.py $< $* > $@

This snippet first downloads a file via FTP and then uses Python to process it. For example, if “Expenditures.txt” is one of my source data files, I can run make data/processed/Expenditures.csv to download and process the expenditure data.

There are two things to note here.

The first is that we use Aria2 to handle FTP duties. Earlier versions of the script used other FTP clients that were either slow as molasses or painful to use. After some trial and error, I found Aria2 did the job better than lftp (which is fast but fussy) or good old ftp (which is both slow and fussy). I also found some incantations that took download times from roughly an hour to less than 20 minutes.

Second, the cleaning step is crucial for this dataset. It uses a simple class-based Python validation scheme you can see here. The important thing to note is that while Python is pretty slow generally, Python 3 is fast enough for this. And as long as you are only processing row-by-row without any objects accumulating in memory or doing any extra disk writes, performance is fine, even on low-resource machines like the servers in ProPublica’s cluster, and there aren’t any unexpected quirks.

Loading

Make is built around file inputs and outputs. But what happens if our data is both in files and database tables? Here are a few valuable tricks I learned for integrating database tables into Makefiles:

One SQL file per table / transform: Make loves both files and simple mappings, so I created individual files with the schema definitions for each table or any other atomic table-level operation. The table names match the SQL filenames, the SQL filenames match the source data filenames. You can see them here.

Use exit code magic to make tables look like files to Make: Hannah Cushman and Forrest Gregg from DataMade introduced me to this trick on Twitter. Make can be fooled into treating tables like files if you prefix table level commands with commands that emit appropriate exit codes. If a table exists, emit a successful code. If it doesn’t, emit an error.

Beyond that, loading consists solely of the highly efficient PostgreSQL \copy command. While the COPY command is even more efficient, it doesn’t play nicely with Amazon RDS. Even if ProPublica moved to a different database provider, I’d continue to use \copy for portability unless eking out a little more performance was mission-critical.

There’s one last curveball: The loading step imports data to a PostgreSQL schema called raw so that we can cleanly transform the data further. Postgres schemas provide a useful way of segmenting data within a single database — instead of a single namespace with tables like raw_contributions and clean_contributions, you can keep things simple and clear with an almost folder-like structure of raw.contributions and public.contributions.

Post-import Transformations

The Illinois Sunshine code also renames columns and slightly reshapes the data for usability and performance reasons. Column aliasing is useful for end users and the intermediate tables are required for compatibility with the legacy code.

In this case, the loader imports into a schema called raw that is as close to the source data as humanly possible.

The data is then transformed by creating materialized views of the raw tables that rename columns and handle some light post-processing. This is enough for our purposes, but more elaborate transformations could be applied without sacrificing clarity or obscuring the source data. Here’s a snippet of one of these view definitions:

CREATE MATERIALIZED VIEW d2_reports AS
    SELECT
        id as id,
        committeeid as committee_id,
        fileddocid as filed_doc_id,
        begfundsavail as beginning_funds_avail,
        indivcontribi as individual_itemized_contrib,
        indivcontribni as individual_non_itemized_contrib,
        xferini as transfer_in_itemized,
        xferinni as transfer_in_non_itemized,
        # ….
    FROM raw.d2totals
WITH DATA;

These transformations are very simple, but simply using more readable column names is a big improvement for end-users.

As with table schema definitions, there is a file for each table that describes the transformed view. We use materialized views, which, again, are essentially persistently cached versions of standard SQL views, because storage is cheap and they are faster than traditional SQL views.

A Note About Security

You’ll notice we use environment variables that are expanded inline when the commands are run. That’s useful for debugging and helps with portability. But it’s not a good idea if you think log files or terminal output could be compromised or people who shouldn’t know these secrets have access to logs or shared systems. For more security, you could use a system like the PostgreSQL pgconf file and remove the environment variable references.

Makefiles for the Win

My only prior experience with Make was in a computational math course 15 years ago, where it was a frustrating and poorly explained footnote. The combination of obtuse documentation, my bad experience in school and an already reliable framework kept me away. Plus, my shell scripts and Python Fabric/Invoke code were doing a fine job building reliable data processing pipelines based on the same principles for the smaller, quick turnaround projects I was doing.

But after trying Make for this project, I was more than impressed with the results. It’s concise and expressive. It enforces atomic operations, but rewards them with dead simple ways to handle partial builds, which is a big deal during development when you really don’t want to be repeating expensive operations to test individual components. Combined with PostgreSQL’s speedy import tools, schemas, and materialized views, I was able to load the data in a fraction of the time. And just as important, the performance of the new process is less sensitive to varying system resources.

If you’re itching to get started with Make, here are a few additional resources:

In the end, the best build/processing system is any system that never alters source data, clearly shows transformations, uses version control and can be easily run over and over. Grunt, Gulp, Rake, Make, Invoke … you have options. As long as you like what you use and use it religiously, your work will benefit.

          Ticket #29558 (Request for more information on past versions of Python) created      Cache   Translate Page   Web Page Cache   

Hi Team,

Me and my team will be developing our first application in Python and we will be using SQL Server as backend. I wanted to ask one query regarding the versions of Python that have been developed and the ones that are in development.

If we use the current available version of the Python and DJango like - Django version - 2.0.7 and Python version - 3.7.0 and Django-msssql - 1.8 version.

My first question is : Will they work with Sql Server 2012 and will they be compatible working on Windows server?

My second question(and the most important one) is: If all goes well and we deploy application and because of some new feature or for some technical reason, we need to update Python but that updation breaks some existing issue then what could be the possible solution? In other words, if the older version (on which our website is working) is not compatible then what can be done in that case?

Please suggest. It would be of great help if you could help me with the response ASAP.

          Dirhunt - Find Web Directories Without Bruteforce      Cache   Translate Page   Web Page Cache   

Dirhunt is a web crawler optimize for search and analyze directories. This tool can find interesting things if the server has the "index of" mode enabled. Dirhunt is also useful if the directory listing is not enabled. It detects directories with false 404 errors, directories where an empty index file has been created to hide things and much more.

$ dirhunt http://website.com/

Dirhunt does not use brute force. But neither is it just a crawler. This tool is faster than others because it minimizes requests to the server. Generally, this tool takes between 5-30 seconds, depending on the website and the server.
Read more about how to use Dirhunt in the documentation.


Features
  • Process one or multiple sites at a time.
  • Process 'Index Of' pages and report interesting files.
  • Detect redirectors.
  • Detect blank index file created on directory to hide things.
  • Process some html files in search of new directories.
  • 404 error pages and detect fake 404 errors.
  • Filter results by flags.
  • Analyze results at end.

Install
If you have Pip installed on your system, you can use it to install the latest Dirhunt stable version:
$ sudo pip3 install dirhunt
Python 2.7 & 3.4-3.6 are supported but Python 3.x is recommended. Use pip2 on install for Python2.
There are other installation methods available.

Snakes on a plane? Not today. 

TSA agents in Miami intercepted an attempt at smuggling a live python onto a plane on Sunday. In an pun-filled Instagram post, the TSA detailed how a passenger tried to get a ball python from Miami to Barbados by tucking it into an external hard drive. 

Snakes on Barbados are actually quite rare, so an invasive species such as a ball python could cause serious damage to the local ecosystem. 

The python didn't manage to Slytherin to the plane.

          The Kangaroo Court "Trial" Of Monika And Alfred Schaefer In Germany Continues: Latest Updates On This Farce!      Cache   Translate Page   Web Page Cache   
I am still deep into major home renovations, and have little time to sit down these last few days to surf the internet... But I finally got a bit of time this afternoon to post an article or two here at this blog!

I have been waiting patiently for any updates on that ludicrous and truly criminal "trial" in Germany for both Monika and Alfred Schaefer who of course are sitting in that kangaroo court on "charges" of "inciting hate".... And thanks to Lady Michel Renouf, who has been attending this "trial" in the court audience, we now have the following update for all to see...

I also want to thank John Kaminski of course who forwarded the following report via email to myself... And without any further adieu, here is that report here:

SCHAEFER TRIAL, MUNICH, GERMANY, THURSDAY, DAY #4, JULY 5, 2018

SCHAEFER TRIAL, MUNICH, Germany, Thursday, DAY #4, July 5, 2018

Report From the Right End of the Horse

Press correspondent for The Barnes Review and American Free Press, Lady Michèle Renouf writes:


This imprisonment of ordinary citizens asking legitimate questions, will no longer be ignored by the citizens. 
 

PREAMBLE

As explained to me by Scientist of Law Sylvia Stolz: The “Muppet Show” trials (as defined by Defendant Alfred Schaefer) in Munich are occurring in the Germany of today which technically is still without a constitution – for the Basic Law (Grundgesetz) is NOT a State Constitution (Verfassung), since the Federal Republic (Bundesrepublik) is not a State.  
 
Sylvia pointed out that Professor Carlo Schmid (one of the most important constitutional advisers in the development of post-1945 Germany) described the Basic Law to which he was a signatory in 1948 as not a sovereign State constitution, but rather as “Organisationsform einer Modalität der Fremdherrschaft” – an Organisational Form of a Mode of Foreign Domination.  Prof. Schmid explicitly stated that the German people were not sovereign, and that the Basic Law was precisely that – a Basic Law not a Constitution: a transitional holding mechanism of rules and regulations. Thereby the Federal Republic is not a State.
 
Grand Admiral Karl Dönitz was arrested as an alleged war criminal a few days after the signing of a military capitulation. Thereby no Head of State (as Dönitz was for the  German Reich) signed a peace agreement and thus Germany is still a victors’ occupied country. 
This Basic Law was imposed on Occupied Germans by the “victors” – the Western Allies – following the senseless inter-gentile World War 2.  German Citizens were not consulted on this in 1948, in the way German citizens had been democratically consulted in 1933. And so, unlike previous wars, there has never been a negotiated peace treaty with the still-valid German State (Deutsches Reich from 1871) whose authority survives although its on-going existence remains disdained by the Occupying “victor” Allies since 1945.  This is the key to the case the Schaefers are opening in their quest for all to grasp – this, as it were, holding law cornerstone, which they would like to see fall down. 
 
The important implication of this trial is pertinent for us all worldwide.  Apart from a Japanese reporter who came with me for the first day or so of the Munich trial, there was no British or English-speaking reporter on the spot – nor seemingly any other, not of the mainstream media, which means perhaps no foreign journalist will risk handling this topic in Germany because the laws are so ludicrously dangerous.  An unwary foreigner raising an arm publicly in a greeting could find it clapped in handcuffs!  Now a crime is a gesture, thought, opinion, word, insignia rather than a brutal act, anti-social swindle, or property theft. This case requires international eyes.
 
In England, an ex-soldier with an “exemplary record”, Jeremy Bedford-Turner, has been given a 12 months’ custodial sentence for publicly and peacefully informing his fellow citizens at a demo that one exceptionalist-identifying people warrant a “vigilante” police force paid for by the general taxpayers.  Trained and empowered by the genuine police, this “community service” operates on our streets in imitation uniforms, vehicles, and equipment – the only difference is their cars bear the Jewish word Shomrim instead of Police, and their focus is on protecting one select component of the citizenry in Britain’s unelected “multi-culti” experiment. Bedford-Turner allegedly said: “All politicians are nothing but a bunch of puppets dancing to a Jewish tune.”  
 
A State’s law and its law-enforcers are supposed to be for all.  The Volksverhetzung para.130 law under which the Schaefer Siblings are being tried in Germany is imposed upon one sort of opinion and insignia mode and not upon all unpopular political and repellent fashion modes. Attorneys are generally reluctant to defend politically “incorrect” citizens for the real fear of being prosecuted themselves if they seem to act “too well” in the interests of their clients.  Such attorneys who do risk defending their clients by arguing for their case must dance on the wire.

Trial Session: Thursday, DAY #4, July 5, 2018

 
Yesterday’s trial session saw Monika describing herself growing up amidst a well-blessed family even as she mentions that there was a certain stigma about being German after the war (which I can confirm as equally true in other former British dominions like Australia and New Zealand).   These siblings each showed themselves and their family history as far from any cases of what the Prosecution would wish to present as damaged hate-filled personalities.  Monika had presented herself as a former Jasper Park ranger, an environmental activist as a spokesperson for the Jasper Environmental Association, and had run as a candidate for the Green Party in Alberta, Canada. Currently a musician, a violin and viola teacher, she sees herself in essence as a peace-loving “social justice warrior”.  At university she studied Natural Law.  Since making her pacific video on German soil, belatedly to her mother: “Sorry Mum I was Wrong About the Holocaust” –  in Canada, Monika Schaefer has suffered social exclusion and cruel ostracism. Her case did not attract much mainstream media attention, either in Canada or in Germany.  She lacks, perhaps, the notoriety of the late Ernst Zündel, convicted of similar charges by a German court in 2007. Yet Ernst Zündel who spent two years in solitary confinement in the Toronto Detention Centre + a further five years in Mannheim Prison in Germany, emerged still declaring to me in my Telling Films “Unbowed” that “thoughts are free”.  
 
 
I, and my international Winter Solstice 2017 guests, plus those who may view that 11 minutes’ private film about her “The Good Comrade” – https://youtu.be/sf0fbRb_pS8 – will happily confirm that being in Monika Schaefer’s presence is life enhancing.
She spent much naturally generous teaching time in showing a young guest aged nine the fundamentals of the piano and violin.  The same applies to her convivial and generous-spirited brother who likewise seems gifted with natural teaching disposition to foster intellectual enquiry.  The Prosecution will have an impossible task to convince, to the contrary, anyone with a respect for truth and justice …yet that contrariwise will be the goal of the Prosecution.  The law concerns incitement with malicious intent. These siblings are all about educational intent, and like their parents, evidently are prompted by light-hearted civic-mindedness.
Here is a photo spoof intended to illustrate the mocking fun Alfred means to make about the ludicrous criminalising of the Roman salute which in his case he says he is indicating how high his dog can jump!
Curiously, and perhaps not unrelately, Thursday’s session begins with the aggressively theatrical arrest of  a spectator in the public gallery.  An unnamed man is pointed out by the Judge who accuses him of insulting the Prosecutor yesterday on his way out at the end of the day.  (Legal expert Sylvia Stolz points out to me that this Prosecutor is not a ‘State’ Prosecutor because the Federal Republic has no State status in law, for the Basic Law is a holding law since today’s Germany has no Constitutional sovereignty.)   The unnamed man was said to have told the ’State’ Prosecutor that she should be ashamed of herself and experience prison from the inside. It’s a citizen’s harmless opinion – and was not made during the proceedings but afterwards – yet the exceedingly enraged judge ordered the man to spend 4 days in prison for his passing aside.  With the tone of “off with his head!” the shouting judge’s behaviour was reminiscent of the playing cards Queen in Alice in Wonderland.  He then turned on Alfred whom he accused of shaking his head into his hands.  The judge seemed set upon strategically goading an hysterical atmosphere but Alfred did not rise to it, stating only that whatever he said in reply would be “twisted and weaponised” into seeming quite contrary to his character.  
 
The histrionic judge required a brief recess to collect himself.  The Prosecution will have to wind up Alfred if there is any hope of portraying this good-natured man as “aggressive” in order to fit the “menace” charge.  (I witnessed this very technique with the judge at the trial in London of Jeremy Bedford-Turner who like Alfred, is good-natured and prompted by civic-conscientiousness not malice.)  RA Nahrath called for a two hours’ interruption in which again to draw up a complaint about the bias of the leading judge. From 10 a.m. to noon the session was duly suspended to the purpose. When the trial resumed RA Miksche submitted his statement regarding the judge’s partiality, and was told the issue would be considered next week.  
 
The session proper began with the screening of Alfred’s first film to show the commencement of his political awakening. Earlier the judge had tried to limit the viewing of Alfred’s video to the single frame where there appears the banned emblem of a swastika.  Alfred succeeded to insist the court view his entire 63 minutes’ video – The Gatekeepers of 9/11 – Controlled Opposition” .  The facile cherry picking of the judge who had simply wanted to point to the swastika at minute 23 would have meant missing the point that at that period in 2013 Alfred was what he called  “75% still indoctinated with anti-Fascist left-leaning sympathies”. Indeed in this first film, Alfred is using the swastika and referring to fascism and to Goebbels the propagandist in an entirely derogatory politically-correct manner!  This film is in English, with German subtitles.  
 
In this film (at minute 23) the sole purpose (in line with Alfred’s beliefs in 2013) of displaying the swastika is to draw an equivalence between Zionism and “nazism”, as differentiated from Jews and Germans.
 
Two professional translators will be given the task of producing German subtitles for the court, for each of Alfred’s films. 
 
Following the screening, the Prosecution claims Alfred has deployed no facts to simply project upon others his own fantasies.
 
In “The Gatekeepers of 9/11” Alfred focuses on his former hero, famous linguistics professor Noam Chomsky.  He describes the correspondence he had with Chomsky over 9/11 and the scientifically-discredited consensual opinion concerning why the third tower (‘Building 7’) collapsed, though no one even claims it had been struck by a plane.  Alfred cites Russia Today who interviewed Jon Cole (of Architects & Engineers for 9/11 Truth); Elizabeth Woodworth (of consensus911.org); and Dr Graeme Macqueen (Eyewitness Research) who relies on 118 witnesses which include the first fire-fighting responders.  Alfred was prompted to write to his hero Chomsky after being “disappointed” with Chomsky’s “denigrating and dismissing” the status of the scientists, architects and engineers as a tiny bunch of “people who spend one hour on the internet and think they know everything”.
 
Chomsky’s recorded attitude towards those scientists whom he denigrates as unserious reminds me of The Holocaust Industry author Norman Finkelstein. During a 2006 television discussion between two guests – Finkelstein and myself – the self-promoting ‘political scientist’ disdained all participants (which included university professors) at the Teheran Conference 2006 (an all-sides, open debate on ‘The Holocaust – A Global Review’) as only “kitchen-sink people”. In his film Alfred says Chomsky displayed “evasive behaviour as well as denigrating the vast community of architects and engineers and other concerned citizens” as a mere “small, isolated clique – your problem, not mine”. The film continues with his being interviewed by Christopher Bollyn. The correspondence Alfred pursues with Chomsky is at no time anything other than respectful and cordial, never aggressive: even as Chomsky accuses him of “insults”, Alfred thanks him for “taking up so much of his precious time” to correspond with him.  There is no basis for the Judge’s contention that Alfred was aggressive and disrespectful towards Chomsky.
 
Alfred’s two questions to “each and every one” of his viewers are:
1) When did you become informed about what really happened on 9/11?
2) What did you do with the knowledge?
 
These questions do not seem “incitement” to violence; rather they are “incitement” to intellectual enquiry.
 
Alfred questions Chomsky about his “denial” of the evidence that the official version of 9/11 depends on asserting facts that are scientifically impossible – that “are only possible if you believe in magic”.
 
This brings to mind the incident during the 1980s Toronto trials of Ernst Zündel.  Canadian Attorney Douglas Christie cross-examined the doyen of “Holocaust” historians Dr Raul Hilberg.  Christie asked whether this eminent academic can produce any form of written order to carry out industrial, mass homicidal gassing of Jews.  Dr Hilberg replies: “I am at a loss.”  Hilberg repeated his view that the “Holocaust” had been achieved by “an incredible meeting of minds, a consensus-mind reading by a far-flung bureaucracy”.  (He had first used these words in a lecture in 1982, and research for Zündel’s defence team by Prof. Robert Faurisson, a specialist in precise documentary analysis, had given Doug Christie the devastating material for his revelatory cross-examination.)
 
President Bush’s “Homeland Security” czar Michael Chertoff (a dual U.S.-Israeli national) is highlighted in Alfred’s film.  Chertoff “allowed the crucial evidence to be destroyed” – physical evidence from the 9/11 scene, such as the buildings’ steel structures – rather than allowing it to be properly analysed.  “Nearly all of this crucial evidence wound up being hastily chopped up into small pieces in New Jersey scrap yards and shipped to China, where it was melted down.”  Alfred describes this as “a clear case of the criminal destruction of evidence”, for which Michael Chertoff (“the son of an Israeli Mossad agent, Livia Eisen”) was responsible.
 
Side-lining of evidence is standard practice in German courts.  For example I witnessed the trial of Germar Rudolf, the Planck Institute chemist who had gone to Auschwitz following the pioneering example of U.S. execution technology expert Fred Leuchter. The evidential exhibits which Germar wished to present to the court in support of his case were in themselves disdained by the court as contravening the doctrine that orthodox “Holocaust history” is to be deemed “manifestly obvious” (“offenkundig”), hence escaping scientific scrutiny – any dissent being condemned as criminal heresy.  Yet another example of where an attorney defending a case can face prosecution if appearing to “defend their client too well”.
 
In the manner of a schoolteacher giving “a lesson”, Alfred concludes: “one very positive thing about 9/11 (every cloud has a silver lining!) is that it has rekindled interest in other strange events of the past, such as Israel’s attack on the USS Liberty, which some people are not even aware of”.
 
Specifically addressing “my Jewish friends”, Alfred said “you are completely innocent of wrongdoing; you have only been deceived and brainwashed like almost all of us were.  And now that you know, it is of utmost importance to reach out to your friends and neighbours [to inform them] before they come to you”.  Yet the Judge accused Alfred of insulting Jews.  It is likewise clear in the film that Alfred speaks in polite, non-threatening terms when, under the heading of “Chomsky Stumbles” he expresses his disappointment that “Chomsky places tribal instincts above his sense of humanity”. 
 
The overall accusation seems to be, that Alfred’s behaviour and his videos are the product of an inherently aggressive nature, and that in his videos Alfred supposedly makes threats against people who have a different opinion.  As evidence of the effects of this alleged “aggression” the Prosecution has pointed to the behaviour of the man in the public gallery who spoke after the close of yesterday’s proceedings to the Prosecutor.  Obviously this little drama was being deployed in order to present Alfred as a very aggressive person, despite the evidence of this film that Alfred is clearly of a patient school teacher’s disposition.
 
During the trial session on Thursday July 5 the judge clearly tried to corner Alfred with this: he accused Alfred, after the German version of his video
Ende der Lüge” (“End of the Lie”) was shown, of making threats in his video. Alfred answered, that there is a difference between threatening and warning.
The judge asked him to explain this and Alfred gave a perfect example without hesitating. He said: if you want to swim across the lake on a cold winter’s day
I will tell you that you should not do this, because you will drown. This is a warning, not a threat!  Frau Schaufer, Alfred’s wife, told me that “The judge began playing around with words like “freiwillig”, which means voluntary, or not “freiwillig”. Even I couldn’t quite follow his train of thought. How should Alfred.  The language Alfred mainly grew up with – at school, university, in his jobs and in everyday and social life – is English. One can clearly notice this, when he speaks openly in German. He is not as fluent and eloquent as he is, when he speaks openly in English. He is not familiar with the subtleties of the German language”.
The explanation by Alfred during the trial, about the difference between a threat and a warning, appears to have something to do with his current arrest, though I do not understand the circumstances.
 
I heard two non-political locals from Munich with whom I got chatting in a cafe say they would not dare take an interest in the trial because they must show their passports to obtain entry to the public gallery.  This they feared might put them on some watch list even though they are in no way party to the issues.  Terror.  I am sure that if citizens in England were legally obliged to submit to revealing their identities before showing an ordinary curiosity about the goings-on in our courts, that many of them, too, would shy away from attending any politically related trial.  Terror, the ‘lynch’-pin of a police-state.  All Alfred is trying to teach would seem to be that legal and ‘State’ prejudice against political free-will to hold and advance an opinion is no longer to be ignored by the citizens.
 
The same is true of Jeremy Bedford-Turner who said to his fellow citizens, “did you know about this?”.  This is public need-to-know. Curiouser and curiouser is this “first the verdict” conduct in “Muppet Show” bewilderland. Heresy fear and persecution avoidance was foreshadowed so aptly by the Monty Python sketch when the Pavlovian trigger response to “Jehovah!” releases a barrrage of stones upon the offending heretic.  This response is no longer restricted to satirical sketches.  I have had my house windows literally stoned repeatedly by Antifa simply for my Telling Films which attempt to record these Trials and tribulations of the likes of the late attorney Manfred Roeder and the late publicist Ernst Zündel. On such occasions these stonings occurred to mark the death of these, in fact, harmless international peace-through-open-debate warriors.
 
RA Nahrath has succeeded after asking the Court to have all Alfred’s videos translated into German.  This means that the Trial dates are now extended into August. The case continues on Thursday July 12thFriday 13th, Monday 16th, plus dates to be announced in August.

New police raid during thought-crime trial in Munich of Canadian-Germans Monika and Alfred Schaefer
 
Alfred Schaefer seized in Police raid at his home

At the home of Alfred Schaefer he and I had just finished watching and discussing matters re his videos he was succeeding to screen in full in the Munich courtroom …and then his wife laid table for lunch after I removed my laptop …and so I went to wash my hands. I then heard Police, a
t 2 pm, knocking on my bathroom door announcing their arrival. It was as if one were suddenly in a nightmare Hollywood movie about a police state action! At first I thought maybe high-spirited Alfred was playing a joke. On opening my bathroom door, there stood 2 armed officers awaiting me.
I handed over my passport; they said they’d come to arrest Alfred. I saw 5 of them handcuff my host.
Taking with him the little packed cheese lunch his experienced wife swiftly made and handed to one officer for her husband, Alfred was hauled away for reasons the police declined to explain to me. Possibly it was about something he had perhaps said when yesterday he had duly turned up at the police station, as he has to do twice per week since he is out on bail. Whatever this “crime” was, he’s again in a police cell now. His wife advised that I and HH should disappear asap in case police returned knowing now that we two were there, easy to haul in for good measure. Vot a business. Cat and mouse – but at least valiant Frau Schaefer made sure we each retrieved the cheese!
 
———-
 

Sunday update, July 8th 2018 

 
Yesterday the magistrate decided that Alfred has to remain in custody in Stadelheim Prison in Munich until the next day of his trial begins, which is Project Euler, CodeWars, or HackerRank -- though I'm totally open to suggestions if anybody has a really good alternate resource! I really love the problem-solving nature of these code challenges, and how I can sometimes can come up with really cool out of the box solutions to them. I do feel like they help me become a stronger programmer, and an added bonus is that if I am interviewing at the time a lot of interview questions are similar to these (for better or for worse).

Since I'm already doing these every day, I thought it would be really cool to share my results on social media to keep me accountable and to see how other people solve the same problem. I normally solve these challenges in Python or JavaScript, but other people have been posting in Ruby, Rust, Ramda, and Clojure so far (which is so cool to see!). Some of them I have solved before at some point, so I post multiple answers in different languages or my refactors!

If you would like to follow along and post your own solutions (or just see other people's), follow me on Twitter or I've been using the hashtag #CodingPuzzle on them, so you could follow there instead! I normally post in between 8 and 9 AM EST since that is normally when I get to work! It's also led to some interesting discussions on efficiency and the strengths of different programming languages for solving these types of problems! These problems are also a variety of difficulties, so if one day's problem is too hard, still follow the next day for a new one!

To get started, today's problem was Project Euler Problem 2: Even Fibonacci Numbers: Each new term in the Fibonacci sequence is generated by adding the previous two terms. Find the sum of the even-valued terms. Please post your answer here!

If you want to catch up on the previous ones, they were:

Hope to see your answers!

Snakes on a plane? Not today. 

TSA agents in Miami intercepted an attempt at smuggling a live python onto a plane on Sunday. In an pun-filled Instagram post, the TSA detailed how a passenger tried to get a ball python from Miami to Barbados by tucking it into an external hard drive. 

Snakes on Barbados are actually quite rare, so an invasive species such as a ball python could cause serious damage to the local ecosystem. 

The python didn't manage to Slytherin to the plane.

I learned that this is not a **canonical Huffman code** (from #25798 ticket i created), so i can't just use the freq to create the Huffman for the decoding. The solution i found is to get the **_tree** and the **_index** attributes from the encode object and replace them in the decode object. So the decode object will have the same **_tree** and **_index** as the encode. Is there any better solution? Sorry for my english. Thanks.

去中心化应用

去中心化应用是可以使用户和供应商之间直接互动的服务(例如,连接某些市场上的买方和卖方,文件存储里的持有者和储存者)。以太坊去中心化应用典型地通过HTML/Javascript网络应用与用户互动,使用Javascript API与区块链通信。去中心化应用典型地在区块链上有自己的相关合约套件,用来编码商业逻辑,允许持久存储对共识要求严格的状态。记住由于以太坊网络上的运算天生冗余,执行的gas成本会比离链的私人执行成本更高。这就激励着去中心化应用开发者限制执行的代码数量和储存在区块链上的代码数量。

去中心化应用目录

使用以太坊的去中心化应用被编译到以下列表,在开发的不同阶段列出(概念,工作原型,实时/部署的)。如果你在开发去中心化应用, 考虑向这些列表添加入口:

  • Ðapps 的Ethercasts状态
  • Dappslist
  • Dappcentral – 去中心化应用的分类页面,带说明,代码验证和网络数据。
  • Dapps邮件列表 – 以太坊上的开发者邮件列表(停止使用)。

列表中提供的去中心化服务覆盖大范围的领域,包括金融,保险,预测市场,社交网络,运算和存储分配,赌博,市场,物联网,管理,合作,开发和游戏。

将来,去中心化应用可能会在去中心化应用浏览器里集成的dappstores中列出和分配。

去中心化应用浏览器

  • Mist – 由基金会开发的官方GUI去中心化应用浏览器,开发阶段。 Mist as Wallet dapp在试用中。
  • Syng – Jarrad Hope开发的移动以太坊浏览器(开发阶段) – 由DEVgrants支持
  • MetaMask – Aaron Kumavis Davis的浏览器内GUI。Github上的Epicenter Bitcoin访谈 – 由DEVgrants支持
  • AlethZero – C++ eth客户端GUI(停止使用)。
  • Supernova – (停止使用)。

开发者工具

去中心化应用开发需要理解Web3 Javascript API, the JSON RPC API和Solidity编程语言。

注意:有开发者工具帮助你开发、测试和部署去中心化应用,自动使用以下列出的资源。

  • Web3 JavaScript API – 想要和以太坊节点交互的时候,主要用到的JavaScript SDK。
  • JSON RPC API – 与节点交互的低级JSON RPC 2.0界面。这个API被Web3 JavaScript API使用。
  • Solidity Docs – Solidity是以太坊开发的智能合约语言,编译到以太坊虚拟机操作码。
  • 测试网络 – 测试网络帮助开发者开发和测试以太坊代码及网络互动,不需花费主网络上自己的以太币。测试网络选项在下面列出。
  • 去中心化应用开发资源。这会帮助你开发,排错和部署以太坊应用。

以太坊控制台

以太坊节点的命令行控制台。

以太坊控制台通过IPC连接到在背景运行的以太坊节点(用eth和geth测试)并提供一个交互的javascript控制台,包括web3对象和管理员附件。

这里可以找到可用管理列表 以太坊节点控制指令

要使用这个控制台,你需要启动一个本地以太坊节点和可用的ipc沟通插口(数据目录中的geth.ipc文件)。开启一个节点后,ipc插口默认位于你的以太坊本地主目录。你也可以设置—test选项来使用特定节点测试指令。

然后你可以在控制台输入

Swarm

Swarm是分布式存储平台以及内容分发服务,以太坊web 3堆栈自带的基层服务。Swarm的首要目标是提供足够去中心化和冗余的以太坊公共记录储存,尤其是储存和分配去中心化应用代码和数据,以及区块链数据。从经济观点看,它允许参与者有效集中储存和带宽资源,用以为所有参与者提供之前提到的服务。

从终端用户的观点看,Swarm和WWW并没有很大不同,除了上载并不是针对一个特定的服务商。目标是点对点存储,并提供抗DDOS、零故障、容错、抗审查的解决方案以及自我维护,这归功于一个使用点对点记账体系并允许以付款交换资源的内置激励体系。Swarm被设计为与以太坊devp2p多协议网络层次,为了域名解决方案的以太坊区块链,服务支付和内容可用性保险结合。

The EVM

以太坊虚拟机(EVM)是以太坊智能合约的执行环境。它不仅被沙箱化,而且实际上是完全隔离的,这意味着以太坊虚拟机内部运行的代码不可以访问网络,文件系统或其他进程。智能合约甚至对其他智能合约的访问权限都是有限的。

合约存在于区块链上,区块链是以太坊特定的二进制格式(以太坊虚拟机字节代码)。然而,合约典型地是用以太坊高级语言写成,用以太坊编译器编译成字节代码,最终用以太坊客户端上传到区块链。

          Tor 0.3.3.8 is released!      Cache   Translate Page   Web Page Cache   
Tor 0.3.3.8 is released! nickm July 09, 2018

Hello, everyone!

We have a new stable release today. If you build Tor from source, you can download the source code for 0.3.3.8 on the website.  Packages should be available within the next several weeks, with a new stable Tor Browser by some time in September. (Don't worry, this isn't an urgent release for clients.)

Tor 0.3.3.8 backports several changes from the 0.3.4.x series, including fixes for a memory leak affecting directory authorities.

Changes in version 0.3.3.8 - 2018-07-09

  • Major bugfixes (directory authority, backport from 0.3.4.3-alpha):
    • Stop leaking memory on directory authorities when planning to vote. This bug was crashing authorities by exhausting their memory. Fixes bug 26435; bugfix on 0.3.3.6.
  • Major bugfixes (rust, testing, backport from 0.3.4.3-alpha):
    • Make sure that failing tests in Rust will actually cause the build to fail: previously, they were ignored. Fixes bug 26258; bugfix on 0.3.3.4-alpha.

 

  • Minor features (compilation, backport from 0.3.4.4-rc):
    • When building Tor, prefer to use Python 3 over Python 2, and more recent (contemplated) versions over older ones. Closes ticket 26372.
  • Minor features (geoip):
    • Update geoip and geoip6 to the July 3 2018 Maxmind GeoLite2 Country database. Closes ticket 26674.
  • Minor features (relay, diagnostic, backport from 0.3.4.3-alpha):
    • Add several checks to detect whether Tor relays are uploading their descriptors without specifying why they regenerated them. Diagnostic for ticket 25686.
  • Minor bugfixes (circuit path selection, backport from 0.3.4.1-alpha):
    • Don't count path selection failures as circuit build failures. This change should eliminate cases where Tor blames its guard or the network for situations like insufficient microdescriptors and/or overly restrictive torrc settings. Fixes bug 25705; bugfix on 0.3.3.1-alpha.
  • Minor bugfixes (compilation, backport from 0.3.4.4-rc):
    • Fix a compilation warning on some versions of GCC when building code that calls routerinfo_get_my_routerinfo() twice, assuming that the second call will succeed if the first one did. Fixes bug 26269; bugfix on 0.2.8.2-alpha.
  • Minor bugfixes (control port, backport from 0.3.4.4-rc):
    • Handle the HSADDRESS= argument to the HSPOST command properly. (Previously, this argument was misparsed and thus ignored.) Fixes bug 26523; bugfix on 0.3.3.1-alpha. Patch by "akwizgran".
  • Minor bugfixes (memory, correctness, backport from 0.3.4.4-rc):
    • Fix a number of small memory leaks identified by coverity. Fixes bug 26467; bugfix on numerous Tor versions.
  • Minor bugfixes (relay, backport from 0.3.4.3-alpha):
    • Relays now correctly block attempts to re-extend to the previous relay by Ed25519 identity. Previously they would warn in this case, but not actually reject the attempt. Fixes bug 26158; bugfix on 0.3.0.1-alpha.
  • Minor bugfixes (restart-in-process, backport from 0.3.4.1-alpha):
    • When shutting down, Tor now clears all the flags in the control.c module. This should prevent a bug where authentication cookies are not generated on restart. Fixes bug 25512; bugfix on 0.3.3.1-alpha.
  • Minor bugfixes (testing, compatibility, backport from 0.3.4.4-rc):
    • When running the hs_ntor_ref.py test, make sure only to pass strings (rather than "bytes" objects) to the Python subprocess module. Python 3 on Windows seems to require this. Fixes bug 26535; bugfix on 0.3.1.1-alpha.
    • When running the ntor_ref.py test, make sure only to pass strings (rather than "bytes" objects) to the Python subprocess module. Python 3 on Windows seems to require this. Fixes bug 26535; bugfix on 0.2.5.5-alpha.

Tor 0.3.4.4-rc is released! nickm July 09, 2018

Hi!  There's a new release candidate available for download.  If you build Tor from source, you can download the source code for 0.3.4.4-rc from the usual place on the website.  Packages should be available over the coming weeks, with a new alpha Tor Browser release likely some time in Muly.

Remember, this is a release candidate: you should only run this if you'd like to find and report more bugs than usual.

 

Tor 0.3.4.4-rc fixes several small compilation, portability, and correctness issues in previous versions of Tor. This version is a release candidate: if no serious bugs are found, we expect that the stable 0.3.4 release will be (almost) the same as this release.

Changes in version 0.3.4.4-rc - 2018-07-09

  • Minor features (compilation):
    • When building Tor, prefer to use Python 3 over Python 2, and more recent (contemplated) versions over older ones. Closes ticket 26372.
  • Minor features (geoip):
    • Update geoip and geoip6 to the July 3 2018 Maxmind GeoLite2 Country database. Closes ticket 26674.

 

  • Minor features (Rust, portability):
    • Rust cross-compilation is now supported. Closes ticket 25895.
  • Minor bugfixes (compilation):
    • Fix a compilation warning on some versions of GCC when building code that calls routerinfo_get_my_routerinfo() twice, assuming that the second call will succeed if the first one did. Fixes bug 26269; bugfix on 0.2.8.2-alpha.
  • Minor bugfixes (control port):
    • Report the port correctly when a port is configured to bind to "auto". Fixes bug 26568; bugfix on 0.3.4.1-alpha.
    • Handle the HSADDRESS= argument to the HSPOST command properly. (Previously, this argument was misparsed and thus ignored.) Fixes bug 26523; bugfix on 0.3.3.1-alpha. Patch by "akwizgran".
  • Minor bugfixes (correctness, flow control):
    • Upon receiving a stream-level SENDME cell, verify that our window has not grown too large. Fixes bug 26214; bugfix on svn r54 (pre-0.0.1).
  • Minor bugfixes (memory, correctness):
    • Fix a number of small memory leaks identified by coverity. Fixes bug 26467; bugfix on numerous Tor versions.
  • Minor bugfixes (testing, compatibility):
    • When running the hs_ntor_ref.py test, make sure only to pass strings (rather than "bytes" objects) to the Python subprocess module. Python 3 on Windows seems to require this. Fixes bug 26535; bugfix on 0.3.1.1-alpha.

          SAS Viya: DLPyを用いたディープラーニングの判断根拠情報出力      Cache   Translate Page   Web Page Cache   

ディープラーニング&画像処理用Python API向けパッケージ:DLPyでは、DLPyの基本的な機能を紹介しました。その中で、ディープラーニングの判断根拠となり得る情報、つまり入力画像のどこに着目しているのかをカラフルなヒートマップとして出力することができるheat_map_analysis()メソッドに触れました。 今回は、heat_map_analysis()メソッドを使用して、ヒートマップを出力する際に指定可能な有効なオプションに関していくつか紹介します。 GPU活用 ヒートマップ解析時の判別(予測)処理再実行回避 ヒートマップ出力対象画像タイプ(正・誤判別)指定 ヒートマップ出力対象画像指定 1.GPU活用 SAS Viyaのディープラーニングでは、ネットワークの層ごとにGPUを使用するかどうかの指定が可能ですが、ヒートマップを出力する際にも、指定したテストデータをモデルに当てはめての予測処理は実行されることになるので、同様にGPUを使用することが可能です。 GPUを使用することで、ヒートマップ出力の時間を短縮することができます。 2.ヒートマップ解析時の判別(予測)処理再実行回避 最初にheat_map_analysis()メソッドを実行する際には、モデルにテストデータを当てはめて判別(予測)処理が行われますが、以降、heat_map_analysis()メソッドを使用して、必要な判断根拠情報を再出力する際には、最初の実行時に計算された値を再利用するので、都度再計算(判別・予測処理)は行わず、より効率的、迅速に、ヒートマップを出力することができます。 「1.GPU活用」でのheat_map_analysis()メソッドではパラメータとして「data=te_img」が指定され、モデルにテストデータを当てはめていましたが、下記の再実行の例では、このパラメータは指定されず、結果のメッセージにも「Using results from model.predict()」と、実行済みの計算結果が使用されている旨が表示されています。 3.ヒートマップ出力対象画像タイプ(正・誤判別)指定 ディープラーニングのモデルにテストデータを当てはめて判別(予測)した結果として、正しく判定された画像と間違った判定が下された画像があります。 heat_map_analysis()メソッドの「img_type」パラメータを使用し、正:”C”(Correct Classification), 誤:“M”(Miss Classified), すべて:“A”(All)、を指定して該当画像の判断根拠情報を出力することが可能です。 以下は、誤判別された画像(img_type=‘M’)の判断根拠情報出力例です。 画像のどの部分に着目して、間違った判断に至ったのかを確認することができるので、モデル精度を改善するためには、学習用にどのような画像が必要なのかといった、示唆も与えてくれます。 4.ヒートマップ出力対象画像指定 heat_map_analysis()メソッドの「filename / image_id」パラメータを使用し、特定の画像を指定して、出力することも可能です。 以下は、画像ファイルリストの上位2つの画像のヒートマップをファイル名指定で出力している例です。 以下は、画像ファイルリストの先頭の画像のヒートマップをID指定で出力している例です。 上記例の詳細に関しては、こちらのGitfubサイトをご覧ください。  DLPyの詳細に関しては、こちらのGithubサイトをご覧ください。

Book Review & Excerpt
Frank Rosell
Secrets of the Snout: The Dog’s Incredible Nose Hardcover – April 13, 2018 by Frank Rosell (Author), Marc Bekoff (Foreword)

This is a fascinating and encyclopedic look at dogs’ amazing scent abilities. Dogs have 125 to 300 million olfactory cells (compared to our measly 5 million), and 33 percent of their brain is dedicated to interpreting odors. No wonder we call upon their noses to help us locate, detect, track and dig up some extraordinary information. Rosell introduces us to a canine cast of ace sniffers: dogs who can detect when cows are in heat; roundworm in sheep; mites (a potentially fatal skin disease) on chamois in the Italian Alps; and if a zoo’s polar bears are pregnant before they go into hibernation. Then there are the Labs: one in Australia who can detect a bacterial disease in beehives and those who’ve been helping track down Burmese pythons in Florida’s Everglades since 2010. The impressive list of canine scenting accomplishments goes on, and makes for an engrossing and enjoyable story.


Excerpt: A Nose for Truffles

Dogs can learn to recognize different scents even while still in the womb and immediately after birth. If you want to use your dog to find truffles (or something else), it is a good idea to start training early. You can give the puppy’s mother truffles so the puppy learns this scent at an early age. If the mother is fed truffles, the taste goes directly into her breast milk and then on to her puppies. And if you continue with the feeding after the puppy has been born, you have gotten off to a good start in training your dog to develop a particular fascination with the scent of truffles. Some dog owners also spread truffle essence on the mother dog’s teats so the puppy will associate the scent of truffles with something positive. It is important not to feed dogs just any kind of mushroom. Every year there are reports of dogs that are victims of mushroom poisoning. The dog can be fed truffles since they are intended to be eaten and spread by animals. However, other edible mushrooms are not and should not be fed to a dog. Most edible mushrooms are spread by the wind.

Truffle-hunting trials have been held in France since 1969. Here dogs have to find six truffles in a 25 m2 space as quickly as possible and give indications for their finds with their paw. If the dogs eat the truffles, they are disqualified.

          Cygnet Theatre Presents LA CAGE AUX FOLLES For Two Nights Only      Cache   Translate Page   Web Page Cache   

Cygnet's 2018 Summer Benefit promises to be anything but a drag. For two nights only, the six-time Tony Award-winning musical La Cage aux Folles comes to Cygnet Theatre for a staged concert reading. Proceeds benefit Cygnet Theatre's Artist Advocate program, which provides the financial support needed to hire the most talented artists and to pay them a meaningful wage. With book by Harvey Fierstein, lyrics and music by Jerry Herman, and directed by Sean Murray with musical direction by Patrick Marion, the benefit takes place August 6 and 7.

After twenty years of un-wedded bliss Georges and Albin, two men partnered for better-or-worse, get a bit of both when Georges' son announces his impending marriage to the daughter of a bigoted, right-wing politician. Further complicating the situation is the 'family business': Albin and Georges run a drag nightclub in St. Tropez, where Albin is the "star" performer 'Zaza'. Georges reluctantly agrees to masquerade as "normal" when he meets the family of the bride-to-be. But Albin has other plans, with hilarious and heartwarming results.

          用 GraphQL 快速搭建服务端 API      Cache   Translate Page   Web Page Cache   

Glow 从今年 4 月开始为中国的产品「共乐孕」app 的用户开发社区功能,虽然在之前美国的社区的类似的功能都进行过实现,但我们仍然决定要在这次中国的社区产品开发中尝试一些新东西。其中就包括 GraphQL 。

今天的文章中会简单介绍下 GraphQL 和我们在服务器端使用的第三方库-- Graphene-Python, 以及我们选择这个技术的原因。并通过一些简单的例子展现如何快速上手 GraphQL 。

GraphQL 的介绍

什么是 GraphQL

简单来说,GraphQL 是一种查询语言,它被设计出来的初衷是用于提供 API。

与 RESTful 设计不同,GraphQL 一般仅暴露出一个接口供使用,而具体一个请求中需要什么数据,数据怎么样组织完全由 API 的使用者(客户端)来指定。 当然,哪些数据可以被查询,数据的类型是怎么样的,则是由服务端给定的。 指定的方式就是传入一段关于想要的结果(或操作)的描述,服务端保证返回符合要求的结果或报错。

这篇文章不是重点介绍 GraphQL 本身,就不展开讲了,

          Running kicad python scripts on windows      Cache   Translate Page   Web Page Cache   

Ok, I’m not sure if I’m getting closer or further…
I have python.org’s 2.7.15 (yes, I know KiCad is 2.7.14, I hope this isn’t the source of my current issue) before the KiCad python in my user path environment variable. I was able to install both numpy and matplotlib in python.org’s 2.7.15 w/o any issue (I hope) with no mention of not finding gcc.

Now when I try to run the pick and place python script I get:

Fatal Python error: PyThreadState_Get: no current thread

I currently have the following paths (in this order) at the end of my user path variable:

C:\Python27
C:\Python27\Scripts
C:\Program Files\KiCad\lib\python2.7
C:\Program Files\KiCad\bin
C:\Python37
C:\Python37\Scripts

And have additionally created a user environment variable “PYTHONPATH” that so far only contains:

C:\Program Files\KiCad\lib\python2.7\site-packages

(This is the path that I found the pcbnew.py file among others.)

Any more hints on how to crack this nut?

Or is this the expected error for the known bug (wrong kicad api)?

          I thought LevelDB is a good one, so I made client command with Go.      Cache   Translate Page   Web Page Cache   

Suddenly, I looked for KVS that can be used as a library like SQLite and found it in LevelDB.

It was a pleasure to use plyvel of Python's LevelDB library, but I decided to create a client command because I don't want to not write Python every time to retrieve a list or list of keys or to delete unnecessary keys.

And here is the one.

HISTORY OF THE SHOW
Disney's Beauty and the Beast is a musical based upon the 1991 Disney film. After completing tryouts in Houston, Disney's Beauty and the Beast premiered on Broadway on April 18, 1994, starring Susan Egan and Terrence Mann as Belle and Beast respectfully. The musical was a commercial success and well-received by audiences. It has since grossed more than $1.4 billion worldwide and played in thirteen countries and 115 cities. The musical was also nominated for nine Tony Awards and won for Best Costume Design. The production ran on Broadway for 5,461 performances between 1994 and 2007, becoming Broadway's eighth-longest-running production in history.

In 2017, a live-action film of Beauty and the Beast premiered. The film was directed by Bill Condon from a screenplay written by Stephen Chbosky and Evan Spiliotopoulos and co-produced by Walt Disney Pictures and Mandeville Films. The film was a reimagining of Disney's 1991 animated movie, but also included elements of the musical as well such as many new songs written by Alan Menken, but featured his musical classic, "Home," as an instrumental version throughout the film.

Linda is currently involved in writing and producing film projects for Miramax and Revolution studios. She lives in Los Angeles with her husband Lee Flicker and daughter Keaton.

Howard Ashman (Lyrics) is best known as a pivotal creative mind behind the renaissance of Disney animation and his work on The Little Mermaid, Aladdin and Beauty and The Beast (which is dedicated to, "Our friend, Howard Ashman, who gave a Mermaid her voice and a Beast his soul...") Ashman's first love was theater. He was a founder of off-off-Broadway's renowned WPA Theater, where he conceived, wrote and directed God Bless You, Mr. Rosewater, as well as the classic musical, Little Shop of Horrors (both music by Alan Menken). In 1986, he wrote and directed the Broadway musical Smile (music by Marvin Hamlisch). Lamented as a lost treasure of the 1980's theater scene, Smile remains popular on High School and College campuses throughout the country. Howard Ashman died in 1991 from complications of AIDS.

Tim Rice (Lyrics) has worked in music, theater, and film since 1965, when he met Andrew Lloyd Webber, a fellow struggling songwriter. Rather than pursue Tim's ambitions to write rock or pop songs, they turned their attention to Andrew Lloyd Webber's obsession - musical theater. Their first collaboration, The Likes Of Us (lyrics by Tim, music by Andrew), was an unsuccessful show based on the life of Dr. Barnardo, the Victorian philanthropist. Their next three works together were much more successful: Joseph and the Amazing Technicolor Dreamcoat, Jesus Christ Superstar, and Evita. Tim has also worked with other distinguished popular composers such as Elton John (The Lion King, Aida), Alan Menken (Aladdin, King David, Beauty and the Beast), Bjorn Ulvaeus, Benny Andersson (Chess). He worked on From Here to Eternity with music by newcomer Stuart Brayson, coproduced with Lee Menzies, directed by Tamara Harvey and with book by Bill Oakes. It premiered in the West End at the Shaftesbury Theatre in 2013. He formed his own cricket team in 1973 and was president of the MCC in 2002. In 2013, he wrote and presented a 52-part series for BBC Radio 2, American Pie, a trawl through the music and musicians of every American State.

          Mquery:一款带有Web前端的YARA恶意软件查询加速器      Cache   Translate Page   Web Page Cache   
搜索特定恶意软件样本很困难?不用怕,今天给大家介绍一款名叫Mquery的工具,它带有友好的Web前端界面,可帮助大家迅速寻找到自己想要的恶意软件样本。多亏了我们的UrsaDB数据库,正是因为有了它,Mquery才可以在一眨眼的功夫给到你想要的数据。 工作机制 YARA的速度毋庸置疑,但是通过给定的数据签名来搜索大型数据库相对来说还是比较慢的。为了解决这个问题,我们实现了一个名叫UrsaDB的自定义数据库,它可以对结果进行预过滤,因此我们只需要运行YARA搜索一小段数据或代码即可: 工具安装(Docker) 建议大家使用docker-compose来构建项目源码: git clone --recurse-submodules https://github.com/CERT-Polska/mquery.git docker-composeup --scale daemon=3 其中“–scale daemon=…”指定的是选择或索引的同步进程任务数量。 注意:“docker-compose”必须支持docker-compose.yml v3语句,如果工具遇到问题,可尝试更新你的软件。 工具安装(手动) 1.运行ursadb数据库;   2.安装redis-server和Python2;   3.安装依赖组件:pipinstall-rrequirements.txt;   4.将config.example.py重命名为config.py,并对相关配置进行调整,设置单独的SECRET_KEY;   5.在Web服务器中搭建并设置Flask应用(webapp.py);   6.运行daemon.py(一个可以持续运行的脚本文件)。 工具使用 1.搭建环境,完成工具的安装; 2.在浏览器输入http://localhost:80/访问Web界面; 3.可在/var/lib/docker/volumes/mquery_samples/_data中查询主机托管的索引文件,可使用“docker image inspect mquery_samples”命令对样本进行调试; 4.打开Web接口,选择“admin”标签,点击“Index /mnt/samples”; 5.在索引过程中,当前运行进程可在“admin”标签下的“backend”部分查看到,ursadb也会定期在终端显示结果数据; 6.成功索引之后,你的文件将可被搜索到,切换到主标签页,上传相应Yara,例如: ruleemotet4_basic: trojan {     meta:         author = "psrok1/mak"         module = "emotet"     strings:         $emotet4_rsa_public = { 8d ?? ?? 5? 8d?? ?? 5? 6a 00 68 00 80 00 00 ff 35 [4] ff 35 [4] 6a 13 68 01 00 01 00 ff 15[4] 85 }         $emotet4_cnc_list = { 39 ?? ?5 [4] 0f44 ??

*本文原创作者:flagellantX,属于FreeBuf原创奖励计划,未经许可禁止转载 通篇是一个模拟的思路架构,以及一些演示,朋友们有了点以后肯定能耍的比我⑥~ 环境: win10 runing kali 两个环节:beef-xss钓鱼环节(建议使用服务器)、Nday钓鱼环节(很好用)、钓鱼框架环节(便携好用) 渔具(演示用): ngrok、beef-xss、CVE-2017-17692、CVE-2015-5119、CVE-2016-0189(ms16-051)、setoolkit、spf、weeman 彩蛋环节: 一个钓鱼利器 一个不跟踪搜索引擎 一个最新的web扫描器 几个高匿名的上网小助手 首先我们要让win10的kali跑起来,可以直接前几天专栏的文章,这里简单叙述下。 首先我翻kali官方文档看到这个https://www.kali.org/news/kali-linux-in-the-windows-app-store/  我们接着就可以实操,打开Microsoft store,输入kali linux进行获取应用 获取好了以后在powershell这里按照官方文档运行这段命令 。 关闭windowsdefener或者将kali包加入信任,就可以开始使用了。 安装metasploit的命令是sudo apt-get install metasploit-framework,beef:sudo apt-get install beef-xss,nmap:sudo apt-get install nmap,总而言之kali上的所有工具都可以如此安装而且github上的工具也可以使用git clone。 直接在cmd窗口输入kali即可进入,非常便捷。 beef-xss钓鱼布置: 切换到beef-xss目录,以管理员身份打开beef。 打开ngrok将http流量转发到3000端口。 先在这个目录下删除ngrok的authtoken(如果之前玩过我前面几招的),这样让ngrok可以同时转发多个http端口。 这时候转发一个80端口,配合hsf写入hook搭建一个临时的钓鱼链接。 beef的控制页面和hook地址。 然后很显然这样转发一个beef老是掉,甚至可能连hijack都拿不到,所以我强烈建议你用服务器,不要这样用,但是这个方式可以用于自写前端接收一些账号密码,以及ngrok的http协议多端口转发,所以还是有必要写一下,当然如果你在外网服务器上搭建beef这套,直接就可以用了。  Nady钓鱼环节: 这边开始的就是今天比较重磅的环节。 打开msf,因为都是钓鱼的,使用http协议,一并将ngrok转发到http 9999作为测试使用。 当然你也可以布置不同的转发端口,因为上面我们已经删掉了token。CVE-2017-17692复制ngrok的链接,进行缩短或者如何都可以,我们这里只是测试,如果实战的话我建议你购买钓鱼域名,当然调戏py是无所谓的。 CVE-2015-5119,hackingteam这个nday就转发到8080端口吧。 测试的攻击link在ngrok自取。 CVE-2016-0189(ms16-051针对IE11) 钓鱼框架: 我说过,win10上的kali具备所有kali功能,所以我们可以git clone使用我们想要的脚本来进行攻击测试。 简单的用setoolkit来测试一下。 安装 要等很久,然后cd set /python setup.py install进行安装。 lol,等了两个小时(我的网渣),成功安装了,喜悦的心情不以言表,看一下亲切的set。 测试一下功能。 ok,完全欧98k。 SPF:(https://github.com/flagellantX/SPF) 启动演示: 你要转发到外网也同理。 weeman:(https://github.com/flagellantX/weeman)  运行演示: 以上通篇差不多就结束了,非常感谢你读到这里,因为我花了一下午到晚八点写了这些,当然手残和网速也是因素。 接下来是彩蛋环节: 这个钓鱼利器真的很酷(https://github.com/flagellantX/gophish),使用文档(https://getgophish.com/documentation/)我建议热衷于当渔夫的读者们可以学习一下如何使用,我搜索了一下fb没有人写,如果过段时间还没有写我会写的。 https://github.com/flagellantX/SearX 通过这个脚本可以在kali上打造自己的搜索引擎,比起google它更像duckgogo吧,具体的看怎么用了。 安装 我们来看一下搜索效果: 还可以,该有的都有了 总之很不错的,比国内一些搜索引擎靠谱,至少不会跟踪你。  扫描器的故事: 我在irc看到有一只汪上线了,然后我问他有没有好的漏扫,我的英语还是chinese很english好的,你们可以看的到 扫描器还是挺酷的,但是没能把nsa黑掉有点遗憾。 官网:https://www.vegabird.com/vooki/ 我帮你们打包了教程和安装文件: 链接老是掉,补到微博里了。 https://weibo.com/6008521503/GorsJaj77 匿名性高的一些上网小助手: 1.IPVANISH https://www.ipvanish.com 2.Private https://privatevpn.com/ 3.Nordvpn https://nordvpn.com 4.STRONG VPN https://strongvpn.com 5.Overplay VPN https://www.overplay.net 今天这部分文章有点长(不夸张地说打结尾的现在我自己都忘了我写了啥),视频教程的话近期会在微博贴出,你也不需要完全按照我的方法和步骤去弄,我用ngrok来当实验的想法很简单,你只需要一个本机一个ngrok就可以上战场了,非常便携,还有就是ngrok可以保护我们攻击者的发出ip,如果用服务器的话,你必须采取手段来隐藏你的ip,方法有很多,但一定要采取,不然你的服务器要是不够好,起码也要比fb官网的服务器好吧,如果对同类型玩家发起这类攻击,他/她/它 抓到你服务器的ip粗暴的直接就把你D了,连pwn都懒得,那么钓鱼的意义就不大了,还是老规矩,我是一个很热衷与攻防研究的家伙,如果你喜欢我的东西,我非常欢迎你来找我一起交流些干货,weibo@flagellantX, thanks。 尾部再送个photo。 […]
          Django开发与攻防测试(入门篇)      Cache   Translate Page   Web Page Cache   
最近在培训包括在一些比赛中,python框架方面的攻防需求出现的越来越频繁。 虽然python框架相对于Java、php等的广泛度还略低一点(当然现在的流行程度已经越来越高了),但是我们并不能够因此而忽视其的安全性。比如在一些赛事中就常用flask来出题等等,所以花时间学习python框架的开发与攻防对于web选手来说还是一件比较重要的事情,所以撰写这篇文章,希望可以给一些想要快速入门的同学一点帮助,同时也能共同进步。 如有错误的地方,还请各位师兄与同学斧正。 依稀记得以前用django + semantic ui + mongodb搭博客还是大学一年级的时候,时光匆匆啊…. 一、Django基础开发 以前搭博客用的是1.8.2,还在机子上装着没卸,顺便拿过来用,当然新版本会修复很多bug,尽可能还是要去学习新一些的版本,此篇权当入门篇。 1、下载安装与启动 # 下载django pip install django==1.8.2 -i https://pypi.mirrors.ustc.edu.cn/simple/ # 创建文件夹并启动虚拟环境 virtualenv django_demo cd django_demo source bin/activate # 创建存放django文件的文件夹 mkdir learn_django cd learn_django # 创建项目 python django-admin.py startproject django_web # 创建应用 python manage.py startapp django_app # 编辑django_web中的settings.py文件,将django_app加入到apps中 这样就完成了最基础的搭建 运行服务看一下 2、Django框架中的MVC与MTV MVC是众所周知的模式:model(模型)、view(视图)、controller(控制器) 用户在页面输入url,转交给url控制器,然后根据url匹配相应的视图函数,viwe会去到models取数据,然后models在数据库中取得数据后返回给视图,视图把要展示的数据返回给模版,然后就输出到页面上。 Django也是一个MVC框架,但是在Django中,控制器接受用户输入的部分由框架自行处理,所以django更加关注的是 模型(model)、view(视图)、templates(模版),也就是MTV模型。 请求一个url后,匹配相应的view区,view去models(一个托管数据的层级)查找我们要的数据,然后将数据装载到templates层,然后呈献给我们。两者很像,可以说MTV基于MVC。 3、静态Web开发 创建模版层 当然,要是只想让简单的数据显示在Web页面中,不需要创建模版,直接在views函数中相应回去就可以了,但是还是正规化一点。 在learn_django中创建templates文件夹(如果是IDE创建的django项目会自动创建),这就是我们的模版文件夹,来添加一个可视化的模版index.html <!DOCTYPE html> <html> <head>     <title>Django Learning</title> </head> <body>     <h1>Hellow,Django!</h1>> </body> </html> 创建视图层 视图层通常来说是一个视图函数,与url进行匹配返回传入对应的Web页面 from django.shortcuts import render # Create your views here. def index(request):     return render(request,'index.html') 创建url层 创建url层,根据传入的url来找到我们的视图函数,从而将渲染的模版返回 from django.conf.urls import include, url from django.contrib import […]

          How to write proper PHP      Cache   Translate Page   Web Page Cache   

@spaceshiptrooper wrote:

Ok, so this is getting way out of hand. PHP isn't supposed to be this hard, but apparently, it is. Probably because people really love to copy and paste from tutorial websites that are decades old. Tutorial websites ARE the worst websites to learn PHP from. For one, they don't teach you about security at all. And second, they teach you the wrong way regardless if you know it's wrong or not.

So I am going to discuss about how to write PHP properly in 2018. I'll be discussing about something called Separation of Logic. Some people call this Separation of Concern(s), but I like to call it Separation of Logic. The terms don't really matter right now so you can use them loosely if you want in this topic. Also, remember that this topic is tailored towards beginners.

Separation of Logic or Separation of Concern(s) is pretty much a method or ideology that separates each logic so that you can manage things in an easier manner. For this topic, we are going to try and "mimic" or "use" the idea of MVC. MVC stands for Model, View, Controller. MVC is a pretty standard business idea that many applications use. MVC isn't even just for PHP, you can see MVC in other languages such as C#, Python, and even in Ruby. It's not going to be an actual MVC, we are just going to use the idea of it. We are also going to write this topic in procedural because that's what beginners love to write their PHP in. Short of OO, this is pretty darn close to MVC.

So the first thing we are going to do is determine what kind of action it is. Is it a GET or is it a POST? If it's a GET, what kind of GET is it? Are we going to need the database? This is where we brainstorm and plan how we want our application to work.

Let's start with the basic of this topic. So we're pretty much going to plan things out first. Let's decide that we want to make something simple. Pretty much, a Hello World page. This is simple. So using Separation of Logic, we pretty much will separate our controller from our views.

index.php

<?php
// Create our $helloWorld variable
$helloWorld = 'Hello World!';

// Include our index_views.php file
require_once 'index_views.php';

index_views.php

<!DOCTYPE html>
<html>
<head>
<title>First Hello World Page</title>
</head>

<body>
<p><?php print($helloWorld); ?></p>
</body>
</html>

"Why and how does it work?" you may ask. It's very simple. The index.php file does not rely on the variable to actually have it working. So if say index_views.php file is missing or has a typo, all you would really be seeing is a white page. In your error logs, you'll see a file or directory does not exist error or open file stream error if you don't have permissions to that file. So in reality, the variable actually gets passed down to the index_views.php file.

We are also using require_once because in PHP, the most abused functions are include and echo. They are also the most misunderstood functions in PHP as well. There is a difference between include, require, include_once, require_once. This is why you DO NOT learn from tutorial websites. They are terrible in every aspect.

Let's discuss what the deferences is.

include

  • Includes a file.
  • If a file is missing or has a typo, continue with execution.
  • If a file does not have the right permission for the server to read, continue with execution.

require

  • Includes a file.
  • If a file is missing or has a typo, halt execution either right before or exactly at the required line.
  • If a file does not have the right permission for the server to read, halt execution either right before or exactly at the required line.

include_once

  • Does what include does, but does it once if you are including the same file more than once.

require_once

  • Does what require does, but does it once if you are including the same file more than once.

The reason why it is recommended to use require instead of include is because of what is listed for include. You may not know or care about what those listed bullets mean, but it will be your disadvantage for ignoring those bullets.

Let's make a scenario. Say for example, you have something like the below.

index.php

<?php
include 'Scenario.php';

echo $scenario;

Scenario.php

<?php
$scenario = 'What will happen to this variable?';

Ok, so it looks pretty simple correct? Now, let's say we mistyped Scenario.php and had it like Secnario.php. Notice the c and the e are switched around. Guess what you'll get now? If you installed your development environment correctly and have errors enabled, you'll get an error message saying Undefined index and a file or directory does not exist error. Undefined index errors typically refer to variables that are referenced, but never really created. They are also from referencing associative arrays like $_POST or $_GET that does not contain that index.

But you know for sure that you created the variable $scenario in Scenario.php correct? Well that's the thing. That's what include does. Again, look at the second bullet for include. It says continue with execution. This means that even if we mistyped our Scenario.php file, it will still continue executing. This means that it will try and echo out $scenario. But again, $scenario never really was created so you'll get the Undefined index error.

Now imagine having 500 variables in other files that you are using include for. Guess what you'll be seeing? 500 Undefined index errors. Now you don't know which file is missing and what is going on. You have looked through all your files and you can't find where the problem started from. This is why you don't use include. require will halt exactly at that problem. If Scenario.php doesn't exist, it will stop executing everything. This means that echo $scenario; will never happen. This also gives you a chance to figure out what is going on. Once you have fixed the typo in your require line, the problem will go away and therefore you can continue with your day. That is why we'll be using require_once in this topic.


So let's get back on track. In our first example at the very top, you'll see that we have separated our PHP from our HTML. We have very little PHP in our HTML and that's what we want. The idea of this method is to separate all the PHP heavy stuff and put it in its own file. We will consider these files as "controllers". Any files that the user will access will be our controller. So if they go to https://localhost/test.php, the file test.php will be considered as our "controller". The file index_views.php will be consider as our "views". Really though, you don't have to name them as such. Just name them appropriately.


So I have showed you the simple GET scenario where you can implement this method. Let's dig into something a little more complex. Let's say we want to use POST and in our POST logic, we want to grab data from our database. So let's try it out. So we know that we have to make sure that the request was through POST. We aren't going to be using if(isset($_POST[...])) because this is not the correct way of checking for form submission. This is a dirty hack to bypass form submission checking and form validation. if(isset($_POST[...])) will also fail in certain Internet Explorer versions. The correct way is if($_SERVER['REQUEST_METHOD'] == 'POST'). So let's get this underway.

The generic template for this method will look something like this. We basically check to make sure that it's a POST request. If it isn't do something else. The "something else" can be as simple as redirecting the user back to the original form.

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {

} else {

}

We'll be requiring a config file as well. This is for the database information and we'll be requiring the model file. This method kind of violates the MVC pattern, but usually, you'll have a bootstrap of some sort to load in your model file.

<?php
require_once 'config.php';

if($_SERVER['REQUEST_METHOD'] == 'POST') {

} else {

}

So that's how it'll look like. Let's continue further. So in our config.php file, we'll start by creating a few constants for the database information.

<?php
session_start();

define('DB_HOST', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', 'root');
define('DB', 'test');

That's simple enough. All we pretty much did was start our sessions and created our constants for our database information. Don't worry, no one cares what my database usernames and passwords are. In PHP, you can create constants in 2 ways.

// First way
define('CONSTANT_NAME', 'constant value');

// Second way
const CONSTANT_NAME = 'constant value';

The second way can only be written within classes. But in newer versions of PHP, you can create them outside of classes. We won't get into what classes are because classes will be difficult to example to a beginner who still has no clue what the difference between include and require is. The next step is to create the database connection. We'll be pretty much doing it in the config.php file.

<?php
session_start();

define('DB_HOST', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', 'root');
define('DB', 'test');

$options = [
	PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_OBJ,
	PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING
];

$db = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB, DB_USERNAME, DB_PASSWORD, $options);

If you did it correctly, you should get a PDO Object () if you do a print_r on the $db variable. print_r is for printing arrays or objects. Again, we won't discuss what objects are either because this falls under OO which for beginners, you won't understand a single thing about them. Let's continue further. So we're just going to basically require the model file inside the config.php file like so.

<?php
session_start();

define('DB_HOST', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', 'root');
define('DB', 'test');

$options = [
	PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_OBJ,
	PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING
];

$db = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB, DB_USERNAME, DB_PASSWORD, $options);

require_once 'model.php';

The reason why we are using those options within our PDO connection is because we want to set the default fetch mode to fetch objects since I am an object oriented person. If you want to fetch arrays, replace PDO::FETCH_OBJ to PDO::FETCH_ASSOC. The difference between these 2 is that FETCH_OBJ will set the default fetch mode to use -> while FETCH_ASSOC sets the default fetch mode to use ['']. Then we'll set the error mode to error warning.

So now let's start writing our controller file.

<?php
require_once 'config.php';

if($_SERVER['REQUEST_METHOD'] == 'POST') {

	// Validation here
	if(!isset($_POST['grab']) OR empty($_POST['grab'])) {

		// Just set 1 to this error.
		// There's nothing really special with this variable other than creating it
		// And we'll be referencing it in a little bit.
		$_SESSION['grab_error'] = 1;

		header('Location: index.php'); // Redirect to our index file
		die(); // Die will ignore everything after

	} else {

		print_r($_POST['grab']);

	}

} else {

	require_once 'index_views.php';

	if(isset($_SESSION['grab_error'])) {
		unset($_SESSION['grab_error']);
	}

}

So you typically don't want to print to the screen in a controller, but we're going to do it for testing purposes. I also said not to use if(isset($_POST[...])) before. The only time when if(isset($_POST[...])) is acceptable and an exception is during form validation. Form validation and form submission checking are 2 different things. Form submission checking is meant to check if the form was submitted. Form validation is to validate that the field contains what you want it to contain. For instance, if you have a field for someone's first name, you obviously don't want it to have numbers do you? That's where "form validation" comes in. Using if(isset($_POST[...])) during this time is appropriate because someone might modify the HTML stuff on their side. By not checking in case these fields exist, you will end up with Undefined index errors if someone happens to modify the page on their side. So this is the only time when using if(isset($_POST[...])) is an exception.

We are also unsetting the grab_error session after the index_views.php file because we are going to make it have a kind of feel when they refresh the page, the error message is gone. It doesn't make sense to keep the error message there when the user refreshes the page and they didn't do anything else.

Now let's continue with our index_views.php file.

<!DOCTYPE html>
<html>
<head>
<title>Grab something from the database</title>
</head>

<body>
<?php
if(isset($_SESSION['grab_error'])) {
?>
<p>Please type something into the "grab" text field.</p>
<?php
}
?>

<form action="//<?php print($_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']); ?>" method="POST">
	<input type="text" name="grab" placeholder="Type something into this field."><br>
	<button type="submit">Submit</button>
</form>
</body>
</html>

So in this view file, we are pretty much checking to see if the grab_error session is set. If it is, we display a custom message to the user. We then create our form. We'll "try" to guess what the URL is. You can leave the action attribute empty, but I believe it is best to put a URL there. So when you type something into the "grab" text field, you'll get a POST array with the field grab as an index.

Ok, the next step is to remove the print_r in our controller file and start using our model file to grab data. So let's create our model file.

<?php
function grabData($db, $string) {

	$sql = 'SELECT someRandomColumn, anotherRandomColumn, whyNotAnotherOne FROM myTable WHERE someRandomColumn = :string';
	$prepare = $db->prepare($sql);
	$parameters = [
		':string' => $string
	];

	$prepare->execute($parameters);

	if($prepare->rowCount()) {

		return $prepare->fetchAll();

	} else {

		return false;

	}

}

So in our model file, we pretty much create a function called grabData. This function requires 2 arguments. The first argument is our database connection and the second argument is the string that we want to use from our text field. We are also using Prepared Statements because we are dealing with user inputs. It is always best to use Prepared Statements when dealing with queries that have WHERE, SET, and INSERT in them. These are the queries that will have user input. Stop using ->query or _query. THIS IS UNSAFE to use when dealing with user inputs.

Ok, so we have our model file created, let's implement the very last step in our controller file and we should have everything working.

<?php
require_once 'config.php';

if($_SERVER['REQUEST_METHOD'] == 'POST') {

	// Validation here
	if(!isset($_POST['grab']) OR empty($_POST['grab'])) {

		// Just set 1 to this error.
		// There's nothing really special with this variable other than creating it
		// And we'll be referencing it in a little bit.
		$_SESSION['grab_error'] = 1;

		header('Location: index.php'); // Redirect to our index file
		die(); // Die will ignore everything after

	} else {

		// Validate "grab" first.
		// Assuming you already did.
		$grab = ....;

		$returned = grabData($db, $grab);
		if($returned == false) {

			// The returned result is false.
			// Do something else like give the user a 404 error page or give them an error message.

		} else {

			require_once 'returned_result.php';

		}

	}

} else {

	require_once 'index_views.php';

	if(isset($_SESSION['grab_error'])) {
		unset($_SESSION['grab_error']);
	}

}

So as you can see, assuming you have already done your validations, all we really do that's different is we run the grabData function. Pass in $db from our config.php because the variable $db is global at this point since we required the config.php file. Then we check to see if the results returned false. If it returned false, that means that the string that the user typed doesn't exist within the database. If it did exist, it would trigger the else statement and run the require_once line.

This method is fairly close to MVC. If you take a look at CodeIgniter, you'll see something that's similar.

public function index() {

	$this->load->model('ModelName');

	$this->ModelName->grabData($db, $grab);

}

Do you see anything different from our model call and CodeIgniter's? Other than the OO style, it's pretty much the same. CodeIgniter still needs to load the model file and within the model file, you have the function grabData. It still requires the same set of arguments. Though if you are using a proper MVC application, you don't need to have the $db connection anymore because you'll most likely be able to load the $db connection from within the model file itself. So you'll only be required 1 argument for the model call.


So pretty much wrapping this topic up, we separate all 3 logics and we have a much cleaner work environment that we can manage more smoother.

  • Separate the PHP heavy stuff into the controllers.
  • Separate the HTML stuff into the views.
  • Separate the database calls into the models.

This pretty much runs like an MVC application. And in the future, if you happen to want to switch from this kind of method to using a real MVC application, you can simply transition without a problem because you'll have that mind set of how it's supposed to work already. You would just need to learn OO. You can also use PHP in your views as well. Just have a minimal or things that aren't PHP heavy like moving files or creating files, those would have to go in the controllers.

It looks like I can't reproduce against master anymore as the issue manifests itself on Python 2, sorry for the false alarm Tim.

Here's how the attachment is sent on Python 2

Notice that both use a RFC 2231 filename*= parameter but the value is within double quotes on Python 2 while it isn't on Python 3. That seems to be the reason why GMail rejects the encoded value.

          TrialChain: A Blockchain-Based Platform to Validate Data Integrity in Large, Biomedical Research Studies. (arXiv:1807.03662v1 [cs.DC])      Cache   Translate Page   Web Page Cache   

Authors: Hao Dai, H Patrick Young, Thomas JS Durant, Guannan Gong, Mingming Kang, Harlan M Krumholz, Wade L Schulz, Lixin Jiang

The governance of data used for biomedical research and clinical trials is an important requirement for generating accurate results. To improve the visibility of data quality and analysis, we developed TrialChain, a blockchain-based platform that can be used to validate data integrity from large, biomedical research studies. We implemented a private blockchain using the MultiChain platform and integrated it with a data science platform deployed within a large research center. An administrative web application was built with Python to manage the platform, which was built with a microservice architecture using Docker. The TrialChain platform was integrated during data acquisition into our existing data science platform. Using NiFi, data were hashed and logged within the local blockchain infrastructure. To provide public validation, the local blockchain state was periodically synchronized to the public Ethereum network. The use of a combined private/public blockchain platform allows for both public validation of results while maintaining additional security and lower cost for blockchain transactions. Original data and modifications due to downstream analysis can be logged within TrialChain and data assets or results can be rapidly validated when needed using API calls to the platform. The TrialChain platform provides a data governance solution to audit the acquisition and analysis of biomedical research data. The platform provides cryptographic assurance of data authenticity and can also be used to document data analysis.

          如何在 Fedora 上安装 Pipenv      Cache   Translate Page   Web Page Cache   

Pipenv 的目标是将打包界(bundler、composer、npm、cargo、yarn 等)最好的东西带到 Python 世界来。它试图解决一些问题,并简化整个管理过程。

目前,Python 程序依赖项的管理有时似乎是一个挑战。开发人员通常为每个新项目创建一个虚拟环境,并使用 pip 将依赖项安装到其中。此外,他们必须将已安装的软件包的集合保存到 requirements.txt 文件中。我们看到过许多旨在自动化此工作流程的工具和包装程序。但是,仍然需要结合多个程序,并且 requirements.txt 格式本身并不适用于更复杂的场景。

一个统治它们的工具

Pipenv 可以正确地管理复杂的相互依赖关系,它还提供已安装包的手动记录。例如,开发、测试和生产环境通常需要一组不同的包。过去,每个项目需要维护多个 requirements.txt。Pipenv 使用 TOML 语法引入了新的 Pipfile 格式。多亏这种格式,你终于可以在单个文件中维护不同环境的多组需求。

在将第一行代码提交到项目中仅一年后,Pipenv 已成为管理 Python 程序依赖关系的官方推荐工具。现在它终于在 Fedora 仓库中提供。

在 Fedora 上安装 Pipenv

在全新安装 Fedora 28 及更高版本后,你只需在终端上运行此命令即可安装 Pipenv:

$ sudo dnf install pipenv

现在,你的系统已准备好在 Pipenv 的帮助下开始使用新的 Python 3 程序。

重要的是,虽然这个工具为程序提供了很好的解决方案,但它并不是为处理库需求而设计的。编写 Python 库时,不需要固定依赖项。你应该在 setup.py 文件中指定 install_requires

基本依赖管理

首先为项目创建一个目录:

$ mkdir new-project && cd new-project

接下来是为此项目创建虚拟环境:

$ pipenv --three

这里的 -three 选项将虚拟环境的 Python 版本设置为 Python 3。

安装依赖项:

$ pipenv install requests
Installing requests…
Adding requests to Pipfile's [packages]…
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…

最后生成 lockfile:

$ pipenv lock
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Updated Pipfile.lock (b14837)

你还可以检查依赖关系图:

$ pipenv graph
- certifi [required: >=2017.4.17, installed: 2018.4.16]
- chardet [required: <3.1.0,>=3.0.2, installed: 3.0.4]
- idna [required: <2.8,>=2.5, installed: 2.7]
- urllib3 [required: >=1.21.1,<1.24, installed: 1.23]

Dougal Matthews - Effective Code Review [EuroPython 2016] [19 July 2016] [Bilbao, Euskadi, Spain] (https://ep2016.europython.eu//conference/talks/effective-code-review) Developers usually state that finding defects is the primary motivation for doing code reviews. However, research has shown that the main benefits of code reviews are; knowledge transfer, team awareness and finding alternative solutions. Code reviews when done well are more than just finding defects; it should be a discussion and conversation with other developers about finding the best solutions. We will talk about re-framing code review to encourage open discussions. ----- This talk is for everyone that is already involved in regular code review and those hoping to start. I will talk through the code review process with the aim of making it a better and more useful experience for both the authors and the reviewers. The talk will follow the following rough outline: - Introduction - Why do code reviews - What are we aiming to get out of it - Submitting code for review - How can you help reviewers? - What should you avoid doing? - Removing ownership of the code - Reviewing code - How should you give feedback? - What should you look for? - How can you encourage people to review more? - How to avoid and remove bike-shedding - ... === Original video: https://www.youtube.com/watch?v=uIwl01Nazdg Downloaded by http://huffduff-video.snarfed.org/ on Mon, 09 Jul 2018 15:44:50 GMT Available for 30 days after download

A man tried to bring a python onto a plane in Miami by hiding it inside a hard drive, according to a news report. He and the snake did not make the flight that was headed to Barbados, authorities said.

The incident unfolded Sunday at a screening area of the Miami International Airport. An article in the Miami Herald said Transportation Security Administration officers found the snake inside a piece of checked luggage when a TSA security officer noticed something odd.

Officials did not tell the Herald how big the snake was, why the man said he had the snake and what airline was involved.

Sari Koshetz, a spokeswoman for the TSA, told the newspaper that a bomb expert then examined the bag and found the python – still alive – in the hard drive.

In a Twitter message, Koshetz wrote that the snake was “artfully concealed” inside the hard drive.

“This organic mass was not explosive,” she wrote, “but it shows you can’t hide any threat from us.”

The snake, Koshetz told the paper, was “obviously not an imminent terrorist threat.” Koshetz told the Herald that the snake was a “possible wildlife threat” on a plane. Animals have gotten out on a plane and have been known to “chew through wires with fatal results,” Koshetz said to the Herald.

The snake was taken into custody by the U.S. Fish and Wildlife Service, and the man was fined.

Authorities did not release the man’s name.

There have been other incidents of passengers trying to get animals through airport security checkpoints.

One man strapped snakes and turtles to his body and tried to get past a security checkpoint at the Miami airport, and a woman once hid a snake in her bra at Fort Lauderdale-Hollywood International Airport, according to the Herald.

The Herald said the animals were confiscated before they made it onto a plane.

          Optimizing a Python application with C++ code      Cache   Translate Page   Web Page Cache   

I’ve been working lately in a command line application called Bard which is a music manager for your local music collection. Bard does an acoustic fingerprinting of your songs (using acoustid) and stores all song metadata in a sqlite database. With this, you can do queries and find song duplicates easily even if the songs are not correctly tagged. I’ll talk in another post more about Bard and its features, but here I wanted to talk about the algorithm to find song duplicates and how I optimized it to run around 8000 times faster.

The algorithm

To find out if two songs are similar, you have to compare their acoustic fingerprints. That seems easy (and in fact, it is), but it’s not as straightforward as it seems. A fingerprint (as acoustid calculates it) is not just a number, but an array of numbers, or better said, an array of bits, so you can’t just compare the numbers themselves, but you have to compare the bits in those numbers. If all bits are exactly the same, the songs are considered the same, if 99% of bits are the same then that means there’s a 99% chance it’s the same tune, maybe differing because of encoding issues (like one song being encoded as mp3 with 192 kbits/s and the other with 128 kbits/s).

But there are more things to have in mind when comparing songs. Sometimes they have different silence lengths at the beginning or end, so the bits that we compare are not correctly aligned and they don’t match as they are calculated, but could match if we shifted one of the fingerprints a bit.

This means that to compare two songs, we don’t just have to compare the two fingerprints, but then we have to simulate increasing/decreasing silence lengths at the beginning of a song by shifting its fingerprint and calculate the match level for each shift to see if we improve/worsen the similarity percentage.  Right now, Bard shiftes the array by 100 positions in one direction and then another 100 positions in the other direction, this means that for each song we have to compare the two fingerprints 200 times.

Then, if we want to compare all of the songs in a collection to find duplicates, we need to compare the songs with ID 1 and 2, then we need to compare the song with ID 3 with IDs 1 and 2, and in general, each song with all previous ones. This means for a collection with 1000 songs we need to compare 1000*1001/2 = 500500 songs (or 100100000 fingerprints).

The initial python implementation

Bard is written in python, so my first implementation used a python list to store the array of integers from the fingerprint. For each iteration in which I have to shift the array numbers I prepend a 0 to one fingerprint array and then iterate over them comparing each element. To do this comparison, I xor the two elements and then use a standard good known algorithm to count the bits which are set in a integer:

def count_bits_set(i):
    i = i – ((i >> 1) & 0x55555555)
    i = (i & 0x33333333) + ((i >> 2) & 0x33333333)
    return (((i + (i >> 4) & 0xF0F0F0F) * 0x1010101) & 0xffffffff) >> 24

Let’s use the speed of this implementation as a reference and call it 1x.

First improvement

As a first improvement I tried replacing that bit counting algorithm with gmpy.popcount which was faster and also improved the algorithm by introducing a canceling threshold. This new algorithm stops comparing two fingerprints as soon as it’s mathematically impossible to have a match over the canceling threshold. So for example, if we are iterating the fingerprints and we calculate that even if all remaining bits would match we wouldn’t get at least a 55% match between songs, we just return “different songs” (but we still need to shift songs and try again, just in case).

With these improvements (commit) the comparisons ran at nearly an exact 2x speed.

Enter C++17

At that time,  I thought that this code wouldn’t scale nicely with a large music collection, so I thought Bard needed a much better implementation. Modifying memory is slow and C/C++ allows for much fine grained low-level optimizations, but I didn’t want to rewrite the application in C++ so I used Boost.Python to implement just this algorithm in C++ and call it from the python application. I should say that I found really easy to integrate methods in C++ with Python and I absolutely recommend Boost.Python .

With the new implementation in C++ (commit) I used STL’s vector to store the fingerprints and I added the maximum offsets in advance so I didn’t need to modify the vector elements during the algorithm and I access elements by simulating the shifting offsets. I also use STL’s map to store all fingerprints indexed on a song ID. Finally, I also added another important optimization which is using the CPU’s instructions to calculate bits set by using gcc’s __builtin_popcount.

The best part of this algorithm is that during the comparison algorithm itself, no fingerprint is copied or modified, which translated in a speed of 126.47x . At this point I started calculating another measure: songs compared per second (remember we’re doing 200 fingerprints comparison for each pair of songs). This algorithm gave an average speed of 580 songs/second. Or put another way, to compare our example collection of 1000 songs, this would take 14 min 22 sec (note that we can calculate the original implementation in Python would take approximately 1 day, 6 hours, 16 minutes and 57 seconds).

First try to parallelize the algorithm

I use an i7 CPU to run Bard and I always thought it was a pity that it only used one CPU. Since the algorithm that compares two songs doesn’t modify their data anymore, I thought it might be interesting to parallelize it to allow it to run in all 8 cores at the same time and just coalesce the result of each independent iterations. So I wondered how to do it and noticed that when I compare each song with all previous ones, this is done using a for loop that iterates over a std::map containing all songs that are already processed. Wouldn’t it be nice to have a for-each loop implementation that runs each iteration on a different thread? Well, there is! std::for_each in C++17 allows to specify an ExecutionPolicy with which you can tell it to run the iterations in different threads. Now the bad news: This part of the standard is not completely supported by gcc yet.

So I searched for a for_each implementation and found this stackoverflow question which included one. The problem is that the question mentions the implementation was copied from the C++ Concurrency in Action book and I’m not sure of the license of that code, so I can’t just copy it into Bard. But I can make some tests with it just for measurements purposes.

This increased the speed to 1897x or ~8700 songs/second (1000 songs would be processed in 57 seconds). Impressive, isn’t it? Well… keep reading ��

Second parallelization try

So I needed to find a parallelized for_each version I could use. Fortunately I kept looking and found out that gcc includes an experimental parallel implementation of some algorithms in the C++ standard library which includes __gnu_parallel::for_each (there are more parallelized algorithms documented in that page). You just need to link to the openmp library.

So I ran to change the code to use it and hit a problem: I used __gnu_parallel::for_each but every time I tested, it only ran sequentially! It took me a while to find out what was happening, but after reading the gcc implementation of __gnu_parallel::for_each I noticed it required a random access iterator, but I’m iterating on a std::map and maps have a bidirectional iterator, not a random-access one.

So I changed the code (commit) to first copy the fingerprints from the std::map<int, std::vector<int>> to a std::vector<std::pair<int,std::vector<int>>> and with just that, the same __gnu_parallel::for_each line ran using a pool of 8 threads.

The gcc implementation proved to be faster than the implementation in the stackoverflow question, with a speed of 2442x , ~11200 songs/second and 44 seconds.

The obvious but important improvement I forgot about

While looking at the compiler build Bard I noticed I wasn’t using compiler flags to optimize for speed! So I tested adding -Ofast -march=native -mtune=native -funroll-loops to the compiler (commit). Just that. Guess what happened…

The speed raised to a very nice  6552x, ~30050 songs/second and 16 seconds.

The Tumbleweed improvement I got for free

I’m running openSUSE Tumbleweed in the system I use to develop which as you probably know, is a (very nice) rolling release distribution. One day, while doing these tests, Tumbleweed updated the compiler from gcc 7.3 to using gcc 8.1 by default. So I thought that deserved another measurements.

Just changing the compiler to the newer version increased the speed to 7714x, 35380 songs/second and 14 seconds.

The final optimization

An obvious improvement I didn’t do yet was replacing the map with a vector so I don’t have to convert it before each for_each call. Also, vectors allow to reserve space in advance, and since I know the final size the vector will have at the end of the whole algorithm, I changed to code to use reserve wisely.

This commit gave the last increase of speed, to 7998x, 36680 songs/second and would fully process a music collection of 1000 songs in just 13 seconds.

Conclusion

Just some notes I think are important to keep in mind from this experience:

  • Spend some time thinking how to optimize your code. It’s worth it.
  • If you use C++ and can afford to use a modern compiler, use C++17, it allows you to make MUCH better/nicer code, more efficiently. Lambdas, structured bindings, constexpr, etc. are really worth the time spent reading about them.
  • Allow the compiler to do stuff for you. It can optimize your code without any effort from your side.
  • Copy/Move data as little as possible. It’s slow and many times it can be avoided just by thinking a bit on data structures before starting developing.
  • Use threads whenever possible.
  • And probably the most important note: Measure everything. You can’t improve what you can’t measure (well, technically you can, but you won’t know for sure).

Comedian John Cleese said he is quitting Britain in November because he is “so disappointed” with the UK. The former Monty Python comic said his “particular beef” is with the British newspapers. He revealed he was heading to the “gorgeous” island of Nevis in the Caribbean. He told BBC Two’s Newsnight: “I’m leaving in November. “I actually am leaving. I’m making arrangements now. Cleese said he was “so disappointed with so much about this country at the moment”. The press reform campaigner said he had tried to secure press reform and changes to the voting system but had failed so he was going to “try somewhere else”. Cleese said the standard of debate around Brexit had been “awful” and there had been “dreadful lies” by the right. The comedian said the “George W Bush voters” of the mid-West and south of America have “no sense of irony”. Asked if he meant that they were a “bit thicker”, he replied: “Yes.”

          以太坊智能合约OPCODE逆向之理论基础篇      Cache   Translate Page   Web Page Cache   

作者:Hcamael@知道创宇404区块链安全研究团队

在我们对etherscan等平台上合约进行安全审查时,常常会遇到没有公布Solidity源代码的合约,只能获取到合约的OPCODE,所以一个智能合约的反编译器对审计无源码的智能合约起到了非常重要的作用。

目前在互联网上常见的反编译工具只有porosity[1],另外在Github上还找到另外的反编译工具ethdasm[2],经过测试发现这两个编译器都有许多bug,无法满足我的工作需求。因此我开始尝试研究并开发能满足我们自己需求的反编译工具,在我看来如果要写出一个优秀的反汇编工具,首先需要有较强的OPCODE逆向能力,本篇Paper将对以太坊智能合约OPCODE的数据结构进行一次深入分析。

基础

智能合约的OPCODE是在EVM(Ethereum Virtual Machine)中进行解释执行,OPCODE为1字节,从0x00 - 0xff代表了相对应的指令,但实际有用的指令并没有0xff个,还有一部分未被使用,以便将来的扩展

具体指令可参考Github[3]上的OPCODE指令集,每个指令具体含义可以参考相关文档[4]

IO

在EVM中不存在寄存器,也没有网络IO相关的指令,只存在对栈(stack),内存(mem), 存储(storage)的读写操作

使用的push和pop对栈进行存取操作,push后面会带上存入栈数据的长度,最小为1字节,最大为32字节,所以OPCODE从0x60-0x7f分别代表的是push1-push32

PUSH1会将OPCODE后面1字节的数据放入栈中,比如字节码是0x6060代表的指令就是PUSH1 0x60

除了PUSH指令,其他指令获取参数都是从栈中获取,指令返回的结果也是直接存入栈中

内存的存取操作是MSTOREMLOAD

MSTORE(arg0, arg1)从栈中获取两个参数,表示MEM[arg0:arg0+32] = arg1

MLOAD(arg0)从栈中获取一个参数,表示PUSH32(MEM[arg0:arg0+32])

因为PUSH指令,最大只能把32字节的数据存入栈中,所以对内存的操作每次只能操作32字节

但是还有一个指令MSTORE8,只修改内存的1个字节

MSTORE(arg0, arg1)从栈中获取两个参数,表示MEM[arg0] = arg1

内存的作用一般是用来存储返回值,或者某些指令有处理大于32字节数据的需求

比如: SHA3(arg0, arg1)从栈中获取两个参数,表示SHA3(MEM[arg0:arg0+arg1]),SHA3对内存中的数据进行计算sha3哈希值,参数只是用来指定内存的范围

上面的stack和mem都是在EVM执行OPCODE的时候初始化,但是storage是存在于区块链中,我们可以类比为计算机的存储磁盘。

所以,就算不执行智能合约,我们也能获取智能合约storage中的数据:

eth.getStorageAt(合约地址, slot)   
# 该函数还有第三个参数,默认为"latest",还可以设置为"earliest"或者"pending",具体作用本文不做分析

storage用来存储智能合约中所有的全局变量

使用SLOADSSTORE进行操作

SSTORE(arg0, arg1)从栈中获取两个参数,表示eth.getStorageAt(合约地址, arg0) = arg1

SLOAD(arg0)从栈中获取一个参数,表示PUSH32(eth.getStorageAt(合约地址, arg0))

变量

智能合约的变量从作用域可以分为三种, 全局公有变量(public), 全局私有变量(private), 局部变量

全局变量和局部变量的区别是,全局变量储存在storage中,而局部变量是被编译进OPCODE中,在运行时,被放在stack中,等待后续使用

公有变量和私有变量的区别是,公有变量会被编译成一个constant函数,后面会分析函数之前的区别

因为私有变量也是储存在storage中,而storage是存在于区块链当中,所以相当于私有变量也是公开的,所以不要想着用私有变量来储存啥不能公开的数据。

全局变量的储存模型

不同类型的变量在storage中储存的方式也是有区别的,下面对各种类型的变量的储存模型进行分析

1. 定长变量

第一种我们归类为定长变量,所谓的定长变量,也就是该变量在定义的时候,其长度就已经被限制住了

比如定长整型(int/uint......), 地址(address), 定长浮点型(fixed/ufixed......), 定长字节数组(bytes1-32)

这类的变量在storage中都是按顺序储存

uint a;       // slot = 0
address b;    // 1
ufixed c;     // 2
bytes32 d;    // 3
## 
a == eth.getStorageAt(contract, 0)
d == eth.getStorageAt(contract, 3)

上面举的例子,除了address的长度是160bits,其他变量的长度都是256bits,而storage是256bits对齐的,所以都是一个变量占着一块storage,但是会存在连续两个变量的长度不足256bits的情况

address a;      // slot = 0
uint8 b;        // 0
address c;      // 1
uint16 d;       // 1

在opcode层面,获取a的值得操作是: SLOAD(0) & 0xffffffffffffffffffffffffffffffffffffffff

获取b值得操作是: SLOAD(0) // 0x10000000000000000000000000000000000000000 & 0xff

获取d值得操作是: SLOAD(1) // 0x10000000000000000000000000000000000000000 & 0xffff

因为b的长度+a的长度不足256bits,变量a和b是连续的,所以他们在同一块storage中,然后在编译的过程中进行区分变量a和变量b,但是后续在加上变量c,长度就超过了256bits,因此把变量c放到下一块storage中,然后变量d跟在c之后

从上面我们可以看出,storage的储存策略一个是256bits对齐,一个是顺序储存。(并没有考虑到充分利用每一字节的储存空间,我觉得可以考虑把d变量放到b变量之后)

2. 映射变量
mapping(address => uint) a;

映射变量就没办法想上面的定长变量按顺序储存了,因为这是一个键值对变量,EVM采用的机制是:

SLOAD(sha3(key.rjust(64, "0")+slot.rjust(64, "0")))

比如: a["0xd25ed029c093e56bc8911a07c46545000cbf37c6"]首先计算sha3哈希值:

>>> from sha3 import keccak_256
>>> data = "d25ed029c093e56bc8911a07c46545000cbf37c6".rjust(64, "0")
>>> data += "00".rjust(64, "0")
>>> keccak_256(data.encode()).hexdigest()
'739cc24910ff41b372fbcb2294933bdc3108bd86ffd915d64d569c68a85121ec'
# 
a["0xd25ed029c093e56bc8911a07c46545000cbf37c6"] == SLOAD("739cc24910ff41b372fbcb2294933bdc3108bd86ffd915d64d569c68a85121ec")

我们也可以使用以太坊客户端直接获取:

> eth.getStorageAt(合约地址, "739cc24910ff41b372fbcb2294933bdc3108bd86ffd915d64d569c68a85121ec")

还有slot需要注意一下:

address public a;                       // slot = 0
mapping(address => uint) public b;      // slot = 1
uint public d;                          // slot = 1
mapping(address => uint) public c;      // slot = 3

根据映射变量的储存模型,或许我们真的可以在智能合约中隐藏私密信息,比如,有一个secret,只有知道key的人才能知道secret的内容,我们可以b[key] = secret, 虽然数据仍然是储存在storage中,但是在不知道key的情况下却无法获取到secret

不过,storage是存在于区块链之中,目前我猜测是通过智能合约可以映射到对应的storage,storage不可能会初始化256*256bits的内存空间,那样就太消耗硬盘空间了,所以可以通过解析区块链文件,获取到storage全部的数据。

上面这些仅仅是个人猜想,会作为之后研究以太坊源码的一个研究方向。

3. 变长变量

变长变量也就是数组,长度不一定,其储存方式有点像上面两种的结合

uint a;         // slot = 0
uint[] b;       // 1
uint c;         // 2

数组任然会占用对应slot的storage,储存数组的长度(b.length == SLOAD(1))

比如我们想获取b[1]的值,会把输入的indexSLOAD(1)的值进行比较,防止数组越界访问

然后计算slot的sha3哈希值:

>>> from sha3 import keccak_256
>>> slot = "01".rjust(64, "0")
>>> keccak_256(slot.encode()).hexdigest()
'20ec45d096f1fa2aeff1e3da8a84697d90109524958ed4be9f6d69e37a9140a4'

#
b[X] == SLOAD('20ec45d096f1fa2aeff1e3da8a84697d90109524958ed4be9f6d69e37a9140a4' + X)

# 获取b[2]的值
> eth.getStorageAt(合约地址, "20ec45d096f1fa2aeff1e3da8a84697d90109524958ed4be9f6d69e37a9140a6")

在变长变量中有两个特例: stringbytes

字符串可以认为是字符数组,bytes是byte数组,当这两种变量的长度在0-31时,值储存在对应slot的storage上,最后一字节为长度*2|flag, 当flag = 1,表示长度>31,否则长度<=31

下面进行举例说明

uint i;                // slot = 0
string a = "c"*31;     // 1
SLOAD(1) == "c*31" + "00" | 31*2 == "636363636363636363636363636363636363636363636363636363636363633e"

当变量的长度大于31时,SLOAD(slot)储存length*2|flag,把值储存到sha3(slot)

uint i;                // slot = 0
string a = "c"*36;     // 1
SLOAD(1) == 36*2|1 == 0x49
SLOAD(SHA3("01".rjust(64, "0"))) == "c"*36
4. 结构体

结构体没有单独特殊的储存模型,结构体相当于变量数组,下面进行举例说明:

struct test {
    uint a;
    uint b;
    uint c;
}
address g;
Test e;

# 上面变量在storage的储存方式等同于
address g;
uint a;
uint b;
uint c;

函数

两种调用函数的方式

下面是针对两种函数调用方式说明的测试代码,发布在测试网络上: https://ropsten.etherscan.io/address/0xc9fbe313dc1d6a1c542edca21d1104c338676ffd#code

pragma solidity ^0.4.18;

contract Test {

  address public owner;
  uint public prize;

  function Test() {
    owner = msg.sender;
  }

  function test1() constant public returns (address) {
    return owner;
  }

  function test2(uint p) public {
      prize += p;
  }
}

整个OPCODE都是在EVM中执行,所以第一个调用函数的方式就是使用EVM进行执行OPCODE:

# 调用test1
> eth.call({to: "0xc9fbe313dc1d6a1c542edca21d1104c338676ffd", data: "0x6b59084d"})
"0x0000000000000000000000000109dea8b64d87a26e7fe9af6400375099c78fdd"
> eth.getStorageAt("0xc9fbe313dc1d6a1c542edca21d1104c338676ffd", 0)
"0x0000000000000000000000000109dea8b64d87a26e7fe9af6400375099c78fdd"

第二种方式就是通过发送交易:

# 调用test2
> eth.getStorageAt("0xc9fbe313dc1d6a1c542edca21d1104c338676ffd", 1)
"0x0000000000000000000000000000000000000000000000000000000000000005"
> eth.sendTransaction({from: eth.accounts[0], to: "0xc9fbe313dc1d6a1c542edca21d1104c338676ffd", data: "0xcaf446830000000000000000000000000000000000000000000000000000000000000005"})
> eth.getStorageAt("0xc9fbe313dc1d6a1c542edca21d1104c338676ffd", 1)
"0x000000000000000000000000000000000000000000000000000000000000000a"

这两种调用方式的区别有两个:

  1. 使用call调用函数是在本地使用EVM执行合约的OPCODE,所以可以获得返回值
  2. 通过交易调用的函数,能修改区块链上的storage

一个调用合约函数的交易(比如 https://ropsten.etherscan.io/tx/0xab1040ff9b04f8fc13b12057f9c090e0a9348b7d3e7b4bb09523819e575cf651)的信息中,是不存在返回值的信息,但是却可以修改storage的信息(一个交易是怎么修改对应的storage信息,是之后的一个研究方向)

而通过call调用,是在本地使用EVM执行OPCODE,返回值是存在MEM中return,所以可以获取到返回值,虽然也可以修改storage的数据,不过只是修改你本地数据,不通过发起交易,其他节点将不会接受你的更改,所以是一个无效的修改,同时,本地调用函数也不需要消耗gas,所以上面举例中,在调用信息的字典里,不需要from字段,而交易却需要指定(设置from)从哪个账号消耗gas。

调用函数

EVM是怎么判断调用哪个函数的呢?下面使用OPCODE来进行说明

每一个智能合约入口代码是有固定模式的,我们可以称为智能合约的主函数,上面测试合约的主函数如下:

PS: Github[5]上面有一个EVM反汇编的IDA插件

[     0x0] | PUSH1                | ['0x80']

[    0x3a] | DUP2                 | None
[    0x3b] | EQ                   | None
[    0x3c] | PUSH2                | ['0x66']
[    0x3f] | JUMPI                | None
[    0x40] | DUP1                 | None
[    0x41] | PUSH4                | ['0x8da5cb5b']
[    0x46] | EQ                   | None
[    0x47] | PUSH2                | ['0xa4']
[    0x4a] | JUMPI                | None
[    0x4b] | DUP1                 | None
[    0x4c] | PUSH4                | ['0xcaf44683']
[    0x51] | EQ                   | None
[    0x52] | PUSH2                | ['0xb9']
[    0x55] | JUMPI                | None
[    0x56] | DUP1                 | None
[    0x57] | PUSH4                | ['0xe3ac5d26']
[    0x5c] | EQ                   | None
[    0x5d] | PUSH2                | ['0xd3']
[    0x60] | JUMPI                | None
[    0x61] | JUMPDEST             | None
[    0x62] | PUSH1                | ['0x0']
[    0x64] | DUP1                 | None
[    0x65] | REVERT               | None

反编译出来的代码就是:

def main():
    if CALLDATASIZE >= 4:
        data = CALLDATA[:4]
        if data == 0x6b59084d:
            test1()
        elif data == 0x8da5cb5b:
            owner()
        elif data == 0xcaf44683:
            test2()
        elif data == 0xe3ac5d26:
            prize()
        else:
            pass
    raise

PS:因为个人习惯问题,反编译最终输出没有选择对应的Solidity代码,而是使用Python。

从上面的代码我们就能看出来,EVM是根据CALLDATA的前4字节来确定调用的函数的,这4个字节表示的是函数的sha3哈希值的前4字节:

> web3.sha3("test1()")
"0x6b59084dfb7dcf1c687dd12ad5778be120c9121b21ef90a32ff73565a36c9cd3"
> web3.sha3("owner()")
"0x8da5cb5b36e7f68c1d2e56001220cdbdd3ba2616072f718acfda4a06441a807d"
> web3.sha3("prize()")
"0xe3ac5d2656091dd8f25e87b604175717f3442b1e2af8ecd1b1f708bab76d9a91"
# 如果该函数有参数,则需要加上各个参数的类型
> web3.sha3("test2(uint256)")
"0xcaf446833eef44593b83316414b79e98fec092b78e4c1287e6968774e0283444"

所以可以去网上找个哈希表映射[6],这样有概率可以通过hash值,得到函数名和参数信息,减小逆向的难度

主函数中的函数

上面给出的测试智能合约中只有两个函数,但是反编译出来的主函数中,却有4个函数调用,其中两个是公有函数,另两个是公有变量

智能合约变量/函数类型只有两种,公有和私有,公有和私有的区别很简单,公有的是能别外部调用访问,私有的只能被本身调用访问

对于变量,不管是公有还是私有都能通过getStorageAt访问,但是这是属于以太坊层面的,在智能合约层面,把公有变量给编译成了一个公有函数,在这公有函数中返回SLOAD(slot),而私有函数只能在其他函数中特定的地方调用SLOAD(slot)来访问

在上面测试的智能合约中, test1()函数等同于owner(),我们可以来看看各自的OPCODE:

[    0xa3] | RETURN               | None

所以我们可以得出结论:

address public a;
会被编译成(==)
function a() public returns (address) {
    return a;
}

#

address private a;
function c() public returns (address) {
    return a;
}
等同于下面的变量定义()
address public c;

公有函数和私有函数的区别也很简单,公有函数会被编译进主函数中,能通过CALLDATA进行调用,而私有函数则只能在其他公有函数中进行调用,无法直接通过设置CALLDATA来调用私有函数

回退函数和paypal

在智能合约中,函数都能设置一个paypal,还有一个特殊的回退函数,下面用实例来介绍回退函数

比如之前的测试合约加上了回退函数:

function() {
    prize += 1;
}

则主函数的反编译代码就变成了:

def main():
    if CALLDATASIZE >= 4:
        data = CALLDATA[:4]
        if data == 0x6b59084d:
            return test1()
        elif data == 0x8da5cb5b:
            return owner()
        elif data == 0xcaf44683:
            return test2()
        elif data == 0xe3ac5d26:
            return prize()
    assert msg.value == 0
    prize += 1
    exit()

CALLDATA和该合约中的函数匹配失败时,将会从抛异常,表示执行失败退出,变成调用回退函数

每一个函数,包括回退函数都可以加一个关键字: paypal,表示可以给该函数转帐,从OPCODE层面讲,没有paypal关键字的函数比有paypal的函数多了一段代码:

JUMPDEST             | None
CALLVALUE            | None
DUP1                 | None
ISZERO               | None
PUSH2                | ['0x8e']
JUMPI                | None
PUSH1                | ['0x0']
DUP1                 | None
REVERT               | None

反编译成python,就是:

assert msg.value == 0

REVERT是异常退出指令,当交易的金额大于0时,则异常退出,交易失败

函数参数

函数获取数据的方式只有两种,一个是从storage中获取数据,另一个就是接受用户传参,当函数hash表匹配成功时,我们可以知道该函数的参数个数,和各个参数的类型,但是当hash表匹配失败时,我们仍然可以获取该函数参数的个数,因为获取参数和主函数、paypal检查一样,在OPCODE层面也有固定模型:

比如上面的测试合约,调动test2函数的固定模型就是: main -> paypal check -> get args -> 执行函数代码

获取参数的OPCODE如下

; 0xAF: loc_af
[    0xaf] | JUMPDEST             | None
[    0xb0] | POP                  | None
[    0xb1] | PUSH2                | ['0xd1']
[    0xb4] | PUSH20               | ['0xffffffffffffffffffffffffffffffffffffffff']
[    0xc9] | PUSH1                | ['0x4']
[    0xcb] | CALLDATALOAD         | None
[    0xcc] | AND                  | None
[    0xcd] | PUSH2                | ['0x18f']
[    0xd0] | JUMP                 | None

函数test2的参数p = CALLDATA[4:4+0x20]

如果有第二个参数,则是arg2 = CALLDATA[4+0x20:4+0x40],以此类推

所以智能合约中,调用函数的规则就是data = sha3(func_name)[:4] + *args

但是,上面的规则仅限于定长类型的参数,如果参数是string这种不定长的变量类型时,固定模型仍然不变,但是在从calldata获取数据的方法,变得不同了,定长的变量是通过调用CALLDATALOAD,把值存入栈中,而string类型的变量,因为长度不定,会超过256bits的原因,使用的是calldatacopy把参数存入MEM

可以看看function test3(string a) public {}函数获取参数的代码:

传入的变长参数是一个结构体:

struct string_arg {
    uint offset;
    uint length;
    string data;
}

offset+4表示的是当前参数的length的偏移,length为data的长度,data就是用户输入的字符串数据

当有多个变长参数时: function test3(string a, string b) public {}

calldata的格式如下: sha3(func)[:4] + a.offset + b.offset + a.length + a.data + b.length + b.data

翻译成py代码如下:

def test3():
    offset = data[4:0x24]
    length = data[offset+4:offset+4+0x20]
    a = data[offset+4+0x20:length]
    offset = data[0x24:0x24+0x20]
    length = data[offset+4:offset+4+0x20]
    b = data[offset+4+0x20:length]

因为参数有固定的模型,因此就算没有从hash表中匹配到函数名,也可以判断出函数参数的个数,但是要想知道变量类型,只能区分出定长、变长变量,具体是uint还是address,则需要从函数代码,变量的使用中进行判断

变量类型的分辨

在智能合约的OPCDOE中,变量也是有特征的

比如一个address变量总会 & 0xffffffffffffffffffffffffffffffffffffffff:

PUSH1                | ['0x0']
SLOAD                | None
PUSH20               | ['0xffffffffffffffffffffffffffffffffffffffff']
AND                  | None

上一篇说的mapping和array的储存模型,可以根据SHA3的计算方式知道是映射变量还是数组变量

再比如,uint变量因为等同于uint256,所以使用SLOAD获取以后不会再进行AND计算,但是uint8却会计算& 0xff

所以我们可以SLOAD指令的参数和后面紧跟的计算,来判断出变量类型

智能合约代码结构

部署合约

在区块链上,要同步/发布任何信息,都是通过发送交易来进行的,用之前的测试合约来举例,合约地址为: 0xc9fbe313dc1d6a1c542edca21d1104c338676ffd, 创建合约的交易地址为: 0x6cf9d5fe298c7e1b84f4805adddba43e7ffc8d8ffe658b4c3708f42ed94d90ed

查看下该交易的相关信息:

  to: null,
  transactionIndex: 4,
  v: "0x2a",
  value: 0
}

我们可以看出来,想一个空目标发送OPCODE的交易就是创建合约的交易,但是在交易信息中,却不包含合约地址,那么合约地址是怎么得到的呢?

function addressFrom(address _origin, uint _nonce) public pure returns (address) {
        if(_nonce == 0x00)     return address(keccak256(byte(0xd6), byte(0x94), _origin, byte(0x80)));
        if(_nonce <= 0x7f)     return address(keccak256(byte(0xd6), byte(0x94), _origin, byte(_nonce)));
        if(_nonce <= 0xff)     return address(keccak256(byte(0xd7), byte(0x94), _origin, byte(0x81), uint8(_nonce)));
        if(_nonce <= 0xffff)   return address(keccak256(byte(0xd8), byte(0x94), _origin, byte(0x82), uint16(_nonce)));
        if(_nonce <= 0xffffff) return address(keccak256(byte(0xd9), byte(0x94), _origin, byte(0x83), uint24(_nonce)));
        return address(keccak256(byte(0xda), byte(0x94), _origin, byte(0x84), uint32(_nonce))); // more than 2^32 nonces not realistic
    }

智能合约的地址由创建合约的账号和nonce决定,nonce用来记录用户发送的交易个数,在每个交易中都有该字段,现在根据上面的信息来计算下合约地址:

# 创建合约的账号 from: "0x0109dea8b64d87a26e7fe9af6400375099c78fdd",
# nonce: 228 = 0xe4 => 0x7f < 0xe4 < 0xff

创建合约代码

一个智能合约的OPCODE分为两种,一个是编译器编译好后的创建合约代码,还是合约部署好以后runtime代码,之前我们看的,研究的都是runtime代码,现在来看看创建合约代码,创建合约代码可以在创建合约交易的input数据总获取,上面已经把数据粘贴出来了,反汇编出指令如下:

; 0x0: main
[     0x0] | PUSH1                | ['0x80']
[     0x2] | PUSH1                | ['0x40']
[     0x4] | MSTORE               | None
[     0x5] | CALLVALUE            | None
[     0x6] | DUP1                 | None
[     0x7] | ISZERO               | None
[     0x8] | PUSH2                | ['0x10']
[     0xb] | JUMPI                | None
[     0xc] | PUSH1                | ['0x0']
[     0xe] | DUP1                 | None
[     0xf] | REVERT               | None
----------------------------------------------------------------
; 0x10: loc_10
[    0x10] | JUMPDEST             | None
[    0x11] | POP                  | None
[    0x12] | PUSH1                | ['0x0']
[    0x14] | DUP1                 | None
[    0x15] | SLOAD                | None
[    0x16] | PUSH1                | ['0x1']
[    0x18] | PUSH1                | ['0xa0']
[    0x1a] | PUSH1                | ['0x2']
[    0x1c] | EXP                  | None
[    0x1d] | SUB                  | None
[    0x1e] | NOT                  | None
[    0x1f] | AND                  | None
[    0x20] | CALLER               | None
[    0x21] | OR                   | None
[    0x22] | SWAP1                | None
[    0x23] | SSTORE               | None
[    0x24] | PUSH2                | ['0x24f']
[    0x27] | DUP1                 | None
[    0x28] | PUSH2                | ['0x32']
[    0x2b] | PUSH1                | ['0x0']
[    0x2d] | CODECOPY             | None
[    0x2e] | PUSH1                | ['0x0']
[    0x30] | RETURN               | None

代码逻辑很简单,就是执行了合约的构造函数,并且返回了合约的runtime代码,该合约的构造函数为:

function Test() {
    owner = msg.sender;
}

因为没有paypal关键字,所以开头是一个check代码assert msg.value == 0

然后就是对owner变量的赋值,当执行完构造函数后,就是把runtime代码复制到内存中:

CODECOPY(0, 0x32, 0x24f)  # mem[0:0+0x24f] = CODE[0x32:0x32+0x24f]

最后在把runtime代码返回: return mem[0:0x24f]

在完全了解合约是如何部署的之后,也许可以写一个OPCODE混淆的CTF逆向题

总结

通过了解EVM的数据结构模型,不仅可以加快对OPCODE的逆向速度,对于编写反编译脚本也有非常大的帮助,可以对反编译出来的代码进行优化,使得更加接近源码。

在对智能合约的OPCODE有了一定的了解后,后续准备先写一个EVM的调试器,虽然Remix已经有了一个非常优秀的调试器了,但是却需要有Solidity源代码,这无法满足我测试无源码的OPCODE的工作需求。所以请期待下篇《以太坊智能合约OPCODE逆向之调试器篇》
