Lossless Float Image Compression
Back in 2021 I looked at OpenEXR lossless compression options (and I think my findings led a change of the default zip compression level , as well as change of the compression library from zlib to libdeflate . Yay blogging about things!) . Then in 2023 I looked at losslessly compressing a bunch of floating point data…

Most RESTful APIs aren't really RESTful
When talking about REST, it is worth reading the dissertation of Roy Thomas Fielding. The original paper that describes RESTful web, “Architectural Styles and the Design of Network-based Software Architectures” Roy T. Fielding (2000), introduces the Representational State Transfer (REST) architectural style as a…

Breaking Git with a carriage return and cloning RCE
tl;dr: On Unix-like platforms, if you use git clone --recursive on an untrusted repo, it could achieve remote code execution. Update to a fixed version of Git and other software that embeds Git (including GitHub Desktop).

Adding a feature because ChatGPT incorrectly thinks it exists
At Soundslice, our sheet music scanner digitizes music from photographs, so you can listen, edit and practice. We continually improve the system, and I keep an eye on the error logs to see which images are getting poor results.

Building the Rust Compiler with GCC
If you know one thing about me, it is that I love working on the Rust compiler. Some people kayak, travel or play guitar - and I stare at assembly, trying to figure out what I broke.

Async Queue – One of my favorite programming interview questions
For the past 7+ years, I've been conducting a programming interview that has been a true personal favorite of mine. It was passed down to me from good friends (Jeremy Kaplan and Carl Sverre, and it was the latter whom I believe invented it). This interview has probably been

The messy reality of SIMD (vector) functions
We’ve discussed SIMD and vectorization extensively on this blog, and it was only a matter of time before SIMD (or vector) functions came up. In this post, we explore what SIMD functions are, when they are useful, and how to declare and use them effectively. A SIMD function is a function that processes more than… Read

Prompting LLMs is not engineering
prompt engineering is nothing but an attempt to reverse-engineer a non-deterministic black box for which any of the parameters below are unknown: - training set - weights - constraints on the model - layers between you and the model that transform both your input and the model's output that can change at any time …

Baba Is Eval
Baba is You is a sokoban puzzle game where the rules themselves have to be manipulated to win. (For the uninitiated, the store page should explain the idea best.) The level of abstraction required to solve most levels makes it a formidable reasoning benchmark, with many reasoning steps being completely orthogonal to…
