A colorscheme inspired by gruvbox for mutt and neomutt
Code snippets and small stuff
-
-
A modular vim configuration
A modular and customizable configuation system for vim/gvim/neovim. -
Echo analysis
Produces sound pulses by a notebook speaker, records the acoustic response and does some signal analysis. Uses PulseAudio and ipython/scipy. -
Topological peak detection in two-dimensional data
A simple Python implementation of the 0-th dimensional persistent homology for 2D images. -
oe1archive.py
A little tool to query the Ö1 7 Tage archive online and print the MP3 URLs of selected broadcasts. -
Nagios plugin: check_rdns
check_rdns is a plugin for the system monitoring software Nagios, which allows to check reverse DNS entries using the tool dig. -
bruttonetto.py
A python programm to compute net and gross incomes with Austrian tax rates for social insurance and income taxes. -
gdb cheatsheet
This is actually not a piece of code, but as I frequently forget yet sometimes need the not-so-standard commands of gdb I wrote a little GDB cheatsheet. -
pdf-autorename.sh
SpringerLink makes it very hard to download conference proceedings (which cost money, by the way). One is expected to click on every single PDF and give it a meaningful name (other than fulltext.pdf) manually. -
timer.py
A small python script I wrote to do timings of talks or exams and the like. -
eFindStaleFiles
The python script eFindStaleFiles.py recursively traverses all directories given to the script for files or directories that are not tracked by portage. The blue output is debug output on stderr. -
ÖBB Fahrpläne
The script fetchOebbPlaene.sh fetches the timetables of the Austrian federal railway company. Further it tries to find human readable filenames and creates according soft links. Finally a little index.txt is generated. -
Blender: io_import_off
This is a Blender plugin which imports DEC Object File Format (.off) files. This feature was built-in for blender 2.49 but apparently has been removed for version 2.54 beta. I have implement the input parsing according to this format specification. -
ipeify
A little shell script that automates the conversion of general pdf, eps or svg files to Ipe xml files using the tools pdftoipe and inkscape. Download it here. -
periodicFetch
This little shell script fetches a website periodically. If a given interface shuts down then the script exits automatically (at least after a whole period). -
ooffice-gpg
I frequently execute a decrypt-edit-encrypt cycle with gpg and OpenOffice.org. This can be pretty annoying and therefore I wrote a little shell script that does that for you. Just call ‘ooffice-gpg <file>’ to edit the file with ooffice and transparently decrypt and re-encrypt the file with gpg. But please note that ooffice-gpg has to be executed from a shell to answer to questions from gpg and the script. -
External Editor Mod
When writing larger emails I love to use the External Editor Plugin for Thunderbird so that I can use gvim. One good practice is to set mail composing to plain text format. This avoids the problem of reconverting to a non-monospace font after closing the editor. -
runfinite
Consider the following problem: You want to run automatic software tests and you want to guarantee that a test is finished in a finite amount of time. In other words, you may want to limit the execution time of a process to a specific timespan. -
randcirc
The python package randcirc computes a given number of random circles in the unit square and is able to extract intersection-free arcs covering the circle-set. To do this in reasonable time geometric hashing has been implemented. The code can be easily extended to other objects than circles and arcs. Only a few primtiva have to be implemented for the geometric object wanted. -
MP3 script for mplayer
A little training in Bash scripts: The script can recursively scan directories for mp3s or play them in random order or just repatedly. You can get the script here. The script can be easily modified to show pictures, etc. -
Small C# SMTP-Server
To freshen up my memory I coded a little program in C#: A SMTP server. By the way: I implemented Semaphores and a Consumer-Producer-Queue for this purpose. -
Rubiks Cube in Python and C++
Since I always wanted to know a little about OpenGL I implemented a Rubiks Cube in C++ and in Python. I’m not a graphics-crack, so be flinty. -
Some FPU hacks: Carpet creation
Motivated by slides made by Stefan Schirra I programmed a few lines in C: A sideness test of a point and a line based on determinants is performed in a numerically interesting square of the plane. You may want to download the code here. -
Gnu-assembler: cat
To broaden my programming skills I learned assembler programming under GNU/Linux by reading the book Programming from the Ground Up. This led to a small code snippet which implements a little Unix-like cat tool. -
Sudoku solver in python
I wrote a simple Sudoko solver in python. This is my first little tool I wrote when I teached me Python. It uses a few logical rules to reduce the number of possibilities and if no further simplification is found Backtracking emerges.
