Why the Windows Registry sucks technically (2010)

Why Python 3 Exists
This month I invited to Q&A at PuPPy [https://youtu.be/2XviXtxWKO8?list=PL4S0lvhXvdhIV2C28Ia_DeIeloBrsQBOW] (the Puget Sound Python users group) that eventually led to me explaining why Python 3 came into existence and the whole string/bytes deal. I ended up receiving a compliment on the explanation which

Git is my buddy: Effective Git as a solo developer
At this point, most developers use Git as a tool for collaboration. We have our rote-learned commands to pull, commit, and push. And of course, there's that one coworker who knows a bit more about Git…

What I Hate About Git

Compiling Rust is NP-hard
...though it's not the flagship borrow checking that's at fault. What I noticed, and would like to share with you today, is that the exhaustiveness checking performed by the Rust compiler on match patterns is a superset of the SAT problem.…

Commander Keen's adaptive tile refresh
I have been reading Doom Guy by John Romero. It is an excellent book which I highly recommend. In the ninth chapter, John describes being hit by lightning upon seeing Adaptive Tile Refresh (ATR). That made me realize I never took the time to understand how this crucial piece of tech powers the Commander Keen (CK)…

I made a real-time C/C++/Rust build visualizer
Sometimes software takes a long time to compile just due to how much code it has, like in the LLVM project. But often a build is slower than it could be for dumb, fixable reasons. I’ve had the suspicion that most builds are doing dumb stuff, but I had no way to see it. So I’ve been working on a cross-platform tool to…

Inheritance Often Doesn't Make Sense
There are three different types of inheritance going on. Ontological inheritance is about specialisation: this thing is a specific variety of that thing (a football is a sphere and it has this radius) Abstract data type inheritance is about substitution: this thing behaves in all the ways that thing does and has this…

PostgreSQL: Jsonb has committed
Great news: PostgreSQL introduced jsonb support, which is real data type with binary storage and indexing ! This work is a confluence of two projects - our hstore and json, which were existed in PostgreSQL for years in somewhat incomplete forms - hstore (10 years old!) implements key-value storage…

Raspberry Pi security alarm – the basics
In November last year — I started building a DIY security alarm system, using a Raspberry Pi as the controller. My plan was to make a self-sustained system, using proper alarm hardware — like PIR sensors and sirens. Integration with Home Assistant would be an add-on, not a requirement. I wanted the system to be as…
