AppImage in Golang

Wondering whether it would be a good idea to re-implement AppImage tools in Golang.

Advantages:

  • Maintainable, easy code (unlike "modern C++")
  • Short compilation times
  • Statically linked binaries, no dependencies
  • Synergies with snap?
  • Fun?

Sphinx with Markdown walkthrough for HTML and PDF output

This walkthrough installs Sphinx and configures it to output HTML and PDF from .md. If you install it on a VM, allocate over 25GB storage and multiple processors. You'll need Ubuntu 16.04 LTS, an internet connection, and sudo rights.

This gist contains instructions on setting up FFmpeg and Libav to use VAAPI-based hardware accelerated encoding (on supported platforms) for H.264 (and H.265 on supported hardware) video formats.

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".

An example inetd-like socket-activated service. #systemd #inetd #systemd.socket

README

This is an example of a socket-activated per-connection service (which is usually referred to as inetd-like service). A thorough explanation can be found at http://0pointer.de/blog/projects/inetd.html.

Define a socket unit

The key point here is to specify Accept=yes, which will make the socket accept connections (behaving like inetd) and pass only the resulting connection socket to the service handler.

An example network service with systemd-activated socket in Python. #systemd #python #socket #socket-activation

README

The example below creates a TCP server listening on a stream (i.e. SOCK_STREAM) socket. A similar approach can be followed to create a UDP server on a datagram (i.e. SOCK_DGRAM) socket. See man systemd.socket for details.

An example server

Create an simple echo server at /opt/foo/serve.py.
