Stack size invisibility in C and the effects on "portability"
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. 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…

Software Development Waste
I've looked back at the end of every software project I've ever been on and thought, "If I'd known then what I know now, I'd have been done in half the time." Despite this, I've never thought carefully about exactly where all the time went and why so much of it felt wasted.

The QOI File Format Specification
Last month I announced a toy project called QOI — the Quite OK Image Format . It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression.

Useful algorithms that are not optimized by Jax, PyTorch, or TensorFlow
In some previous blog posts we described in details how one can generalize automatic differentiation to give automatically stability enhancements and all sorts of other niceties by incorporating graph transformations into code generation. However, one of the things which we didn’t go into too much is the limitation of…

Finding a kernel regression in half an hour with git bisect run (2018)
The git bisect command helps you identify the first commit in a range that broke something. You give it a good commit and a bad one, and it will do a binary search between the two to find the first bad commit. At each step, you say either git bisect …
