Grace Hopper’s Revenge
The world of software has lots of rules and laws. One of the most hilarious is Kernighan’s Law: Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. I’ve always understood Kernighan’s […]
Show HN: Pgit – A Git-like CLI backed by PostgreSQL
TL;DR: Built a Git-like CLI backed by PostgreSQL with automatic delta compression. Import any git repo, query its entire history with SQL. Benchmarked on 20 real repositories (273,703 commits): pgit outcompresses git gc –aggressive on 12 out of 20 repositories, while giving you full SQL access to every commit, file version, and change pattern. Then […]
Flash-KMeans: Fast and Memory-Efficient Exact K-Means
Abstract:$k$-means has historically been positioned primarily as an offline processing primitive, typically used for dataset organization or embedding preprocessing rather than as a first-class component in online systems. In this work, we revisit this classical algorithm under the lens of modern AI system design and enable $k$-means as an online primitive. We point out that […]

Every layer of review makes you 10x slower
Every layer of review makes you 10x slower We’ve all heard of those network effect laws: the value of a network goes up with the square of the number of members. Or the cost of communication goes up with the square of the number of members, or maybe it was n log n, or something […]
Video Encoding and Decoding with Vulkan Compute Shaders in FFmpeg
Video encoding and decoding on the internet is largely a solved problem for everyday users. Most consumer devices now ship with dedicated hardware accelerator chips, to which APIs like the Vulkan® Video extensions provide direct access. Meanwhile, newer codecs are increasingly royalty-free with open specifications — or simply age out of licensing restrictions — making […]
