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…
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 […]
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…
After watching a couple of days of GVFS conversation, I want to add a few things. What problems are we solving? GVFS (and the related Git optimizations) really solves 4 distinct problems: A large number of files – Git doesn’t naturally work well with hundreds of thousands or millions of files in your working set…

Here are the slides of my talk “The dawn of formalized mathematics” from the 8th European Congress of Mathematics , which is taking place online and in Protorož, Slovenia, from June 20 to 26, 2021:
If you enjoy this article, I have published a book explaining the internals of Git through implementation: Building Git .
We’ve been working hard over the past five months and are very happy to release Pyston 0.3, the newest version of our high-performance Python implementation. The biggest features of this release ar…
Introduction In this blog, we'll be going over some more advanced topics new in Postgres 16. Having some experience with Linux, Postgres, and SQL is necessary as we'll not only be going over these new features but also how to implement them. This blog was written using PostgreSQL 16 (Development Version) running on…
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…

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…
