SIMD-friendly algorithms for substring searching
0x80.pl — Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr, the C++ class std::string has the method find, Python's string has methods pos and index, and so on, so forth. All these APIs were designed for one-shot searches. During past decades several algorithms to solve this problem were designed, an excellent page by Christian Charras and Thierry Lecroq lists most of them (if not all). Basically these algorithms could be split into two major categories: (1) based on Deterministic Finite Automaton, like Knuth-Morris-Pratt, Boyer Moore, etc., and (2) based on a simple comparison, like the Karp-Rabin algorithm.

Shaping Light – Volumetric Lighting
maximeheckel.com — As I became more familiar with post-processing over the past few months, I was curious to push those newly learned techniques beyond pure stylization to achieve something more functional. I wanted to find new ways to enrich my 3D work which wouldn't be possible without leveraging effects and passes alongside custom shaders. SHAPING, 7

Whatever Happened to Sandboxfs?
substack.com — Back in 2017–2020, while I was on the Blaze team at Google, I took on a 20% project that turned into a bit of an obsession: sandboxfs. Born out of my work supporting iOS development, it was my attempt to solve a persistent pain point that frustrated both internal teams and external users alike: Bazel’s poor sandboxing performance on macOS.

Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Sit tight. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Better be some good in-flight entertainment. In case you're wondering, you'd need about 2000 feature-length movies to occupy that many waking hours. Sit back and relax. Jupiter is more than 3 times as far as we just traveled. Whe... MOON, 17

100 years of Zermelo's axiom of choice: What was the problem with it? (2006)
mietek.io — Cantor conceived set theory in a sequence of six papers published in the Mathematische Annalen during the five year period 1879–1884. In the fifth of these papers, published in 1883,1 he stated as a law of thought (Denkgesetz) that every set can be well-ordered or, more precisely, that it is always possible to bring any well-defined set into the form of a well-ordered set. Now to call it a law of thought was implicitly to claim self-evidence for it, but he must have given up that claim at some point, because in the 1890s he made an unsuccessful attempt at demonstrating the well-ordering principle.2 ZERMELO, 19

Apple's Liquid Glass is prep work for AR interfaces, not just a design refresh
substack.com — Apple's introduction of Liquid Glass at WWDC 2025 represents far more than a visual refresh. It's a calculated strategic repositioning that reveals how the company thinks about the next decade of human-computer interaction. While the design community debates readability and the tech press focuses on the absence of major AI announcements, Apple is quietly executing a playbook that should feel familiar to anyone who remembers the iPhone's introduction: prepare users for a paradigm shift by making the transition feel inevitable.

Prefer software with thousands rather than millions of users, that doesn't change often, that seems to get forked a lot, that can be modified without specialized tools, and, ideally that you can make small changes to.

While I always express gratitude and try to pay it forward, I often feel there's still an imbalance. I feel like I owe something more direct to the specific people who shaped my life. GIVE, 29
