Hi there 👋

Signals are pretty interesting, aren't they? I write about them in my blog, tweets, and code:

📟 redsea

redsea is an RDS decoder for use with RTL-SDR tools. It can even decode RDS-TMC. Written in C++14, using the liquid-dsp library. The name is sort of a pun.

☎️ deinvert

deinvert decodes the voice inversion scrambling used as a sort of privacy filter in some radios. Written in C++11.

💓 bpm

bpm is a command-line tool to measure beats per minute just by hitting enter in the terminal. Written in Perl 5.


Okay, it's not all about signals:

📖 kalevala-grep

kalevala-grep Match all input text lines conforming to the Kalevala trochaic tetrameter. Written in Perl 5.

⛓️ markovtext

markovtext Generate random chains (lines of text) based on sample text data given as input. Written in Perl 5.
