A blog by and for database architects.
Introduction
It happened. Nearly 5 years of paper writing, being snuck Committee Meeting notes on the DL until I could access them myself and absolve my co-conspirators of their sins, 5 different implementations/patches later, I can
Google just launched Gemini 2.5 Pro on March 26th, claiming to be the best in coding, reasoning and overall everything. But I mostly care about how the…
Introducing GPT-5.1-Codex-Max, a faster, more intelligent agentic coding model for Codex. The model is designed for long-running, project-scale work with enhanced reasoning and token efficiency.
Python 3.15’s JIT is now back on track
This article shows how to construct a non-recursive zip bomb that achieves a high compression ratio by overlapping files inside the zip container. "Non-recursive" means that it does not rely on a decompressor's recursively unpacking zip files nested within zip files: it expands fully after a single round of…
In November 2022, I opened issue 99108 on Python’s GitHub repository, arguing that after a recent CVE in its implementation of SHA3, Python should embrace verified code for all of its hash-related infrastructure.
Update Jan 4: Wow, this thing really took off! 1BRC is discussed at a couple of places on the internet, including Hacker News, lobste.rs, and Reddit. For folks to show-case non-Java solutions, there …
A randomized trial with 52 developers found AI assistance lowered comprehension scores, except when used for explanations rather than delegation.

Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
It all started out innocently enough. You experimented with it once or twice in your first year of college, but Nano and Pico were easier—closer to what you had already been using during high school on the Windows machines and Macs. But as time went on and you got more experience under your belt in the college-level…

The website of Justin Long. Crockpotveggies is a collection of notes about Justin's own projects.
About two years ago, I tried to improve the support of the GIF encoding in FFmpeg to make it at least decent. This notably led to the addition of the transparency mechanism in the GIF encoder. While this is not always optimal depending on your source, it is in the most common cases. Still, this was merely an attempt…
Do you recognise these images? There's a good chance you've seen some of them before now, probably several times. Here's a hint: They all depict the same thing.
A detailed walkthrough of the Linux boot process from power button to kernel initialization
TIL this trick, via Pascal Hirsch on Twitter. Enter a line of Bash starting with a # comment, then run !:q on the next line to see what that would be with proper Bash escaping applied.
