Articles about software

  1. A simple feed reader for Youtube

    As an exercise, I wrote a small script to read the Atom feeds for some favourite youtube channels. Of course I could have installed a “real” feed-reader, but that would be overkill and not half as much fun. :-)

  2. Attempting a conky replacement in Python (part 2)

    In part 1 we say that a simple replacement for conky for generating a statusline for i3 can be achieved. But since it uses the subprocess module to call external programs it is pretty CPU intensive.

    The question now is if we can reduce that? For that we’re going to use mmap to look at the mailbox, and call sysctlbyname(3) using ctypes to get the remaining system information. Note that sysctl et al and the names used are specific to FreeBSD.

  3. SHA256 in pure Python

    This is a python implementation of the SHA256 command-line program, for operating systems that lack it.

  4. TeXcalc

    As an engineer, I often do diverse calculations that I want to save in my logbooks which I write in LaTeX. Up to now I’ve either formatted those by hand or used the listings package to include calculations made in IPython.
