EvoGrain: Algorithmic Sound Design with L-Systems and Granular Synthesis
Nathan Ho walks through building EvoGrain, an open-source system that randomly generates L-systems, expands them into command sequences, interprets those as sets of grains, and renders them with granular synthesis, covering inspirations like Iamus, the design of each pipeline stage, and generated sound examples.

Tetris in d dimensions: how we rightsize Kubernetes nodes
Emmanuel Bakare explains how CostGraph rightsizes Kubernetes nodes as a vector bin packing problem: sizing pods from real usage percentiles, checking placements against scheduler hard constraints, and using Dot Product and L2 heuristics from Panigrahy et al. instead of first fit decreasing.

Making np.searchsorted up to 25× Faster in NumPy 2.5
Alejandro Candioti explains how NumPy 2.5 makes np.searchsorted up to 25 times faster by batching many binary searches so their independent memory accesses overlap, starting from a vectorized Python prototype that beat NumPy 2.4's native code, and discusses cache-friendly layouts like Eytzinger as a future direction.

Stelios Petrakis describes building a C raycaster around the maze generation algorithm of the Atari 2600 game Entombed (1983), whose mysterious lookup table builds the maze one row at a time within 128 bytes of RAM, then reskinning it as a Backrooms-style game with a browser-playable Three.js version.

The author designs a compact binary encoding scheme for national flags using a layered model and Huffman coding. Most flags can be represented in 55–76 bits by exploiting the statistical regularity of flag elements — stripes, stars, crescents, common aspect ratios — while allowing longer codes for complex outliers like Qatar.
