How to Write a Video Player in Less Than 1000 Lines
ffmpeg is a wonderful library for creating video applications or even general purpose utilities. ffmpeg takes care of all the hard work of video processing by doing all the decoding, encoding, muxing and demuxing for you. This can make media applications much simpler to write. It's simple, written in C, fast, and can…

A Failed Experiment with Python Type Annotations
I like Python, but wish it had static typing. The added safety would go a long way to improving quality and reducing development time. So today I tried to make use of type annotations and a static type-checker called mypy. After a few basic tests, I was excited. But my glee turned to disappointment rather […]

Rootless Pings in Rust
Sending a ping by creating an ICMP socket normally requires root: you can’t create a raw socket to send ICMP packets without it. The ping command line tool works without root however, how is that possible? It turns out you can create a UDP socket with a protocol flag, which allows you to send the ping rootless. I…

Fixing the iterative damping interpolation in video games
As I'm exploring the fantastic world of indie game development lately, I end up watching a large number of video tutorials on the subject. Even though the quality of the content is pretty variable, I'm very grateful to the creators for it. That being said, I couldn't help noticing this particular bit times and times…

My ideal Rust workflow
Writing Rust is pretty neat. But you know what’s even neater? Continuously testing Rust, releasing Rust, and eventually, shipping Rust to production. And for that, we want more than plug-in for a c...

RaptorQ and performance optimization in Rust
I recently decided to learn more about Rust, and wrote a high performance RaptorQ (RFC6330) library. RaptorQ is a fountain code, and the core of the algorithm is a lot of matrix math over GF(256) – which translates into lots of XORs and reads from lookup tables. After getting the initial implementation working, I set…

Porting Libyaml to Safe Rust: Some Thoughts
The following is a loose collection of thoughts that came up while porting unsafe-libyaml to safe, idiomatic Rust, which may be useful to someone else who is considering "rewriting it in Rust", as the ancient journeyman prayer goes.
