Last month I have been on a multi-day hike with my dad. Each of us took many pictures, and when we came back we put them all in a shared folder. We both have Android phones, and the naming scheme used for our pictures was the same: IMG_YYYYMMDD_HHmmss followed maybe by some other numbers and then a .jpg . Here YYYY…
Most C++ and Rust thread pools run 10x slower than OpenMP on fork-join workloads. Fork Union closes the gap to 20% with 300 lines, dodging mutexes and CAS.
Asynchrony, fast approximate exponents, and 10x more efficient softmax.
Secure the modern software stack with Koi. Gain visibility, context, and real-time protection over extensions, MCPs, and autonomous AI agent endpoints.
I spent 3 weeks earlier this year digging in to and reimplementing the lossless compression algorithm in Fuji’s RAF Camera RAW files. This post discusses the fundamentals of how it works.
Motivation Around 20% of Firefox’s HTTP traffic today uses HTTP/3, which runs over QUIC, which in turn runs over UDP. This translates to substantial UDP I/O activity. Firefox uses NSPR for most of its network I/O. When it comes to UDP I/O, NSPR only offers a limited set of dated APIs, most relevant here PR_SendTo and…
Ship production-quality code at superhuman speed.
I recently purchased the textbook “Aircraft Control and Simulation” by Brian L. Stevens, Frank L. Lewis, and Eric N. Johnson 1 . This book covers the control and simulation of aircraft. It’s really dense and frankly hard to understand. As far as aerodynamics texts go, it’s pretty typical.
std::flip is a little-known utility from the C++ standard library header <functional>: it is a higher-order function that accepts a Callable and returns an equivalent Callable with the order of its parameters reversed (or “flipped”).
Back in 2021 I made a mod for Deus Ex 1 that fixes the lipsyncing and blinking, which, I betcha didn’t know, was broken since ship. Everything I wrote about it is on Twitter, and it oughta be somewhere else, so here’s a post about it. The mod itself can be downloaded here .
There are books & many articles online, like this one arguing for using Postgres for everything. I thought I’d take a look at one use case - using Postgres instead of Redis for caching. I work with APIs quite a bit, so I’d build a super simple HTTP server that responds with data from that cache. I’d start from Redis…
Google is releasing updated Gemini 2.5 Flash and Flash-Lite preview models with improved quality, speed, and efficiency.
I recently attended the Goatmire Elixir Conf and one of the standout talks for me was Saša Jurić’s “Tell Me a Story” . It was an incredible presentation that combined theatrical storytelling with practical technical advice. Saša performed parts of his talk in character, turning technical topics into a compelling…
I’ve spent 15 years of my life working on Bundler. When I introduce myself, people say “oh, the Bundler guy?”, and I am forced to agree. I didn’t come up with the original idea for Bundler (that was Yehuda). I also didn’t work on the first six months worth of prototypes. That was all Carl and Yehuda together, back…
The challenge, simulate millions of particles in golang, multi-player enabled, cpu only, smart tv compatible.
The critical section may be an old dog, but it's still learning new tricks.
From the Zed Blog: We're moving Zed AI from prompt-based limits to token-based pricing.
Apache Sedona is a cluster computing system for processing large-scale spatial data. Sedona extends existing cluster computing systems, such as Apache Spark, Apache Flink, and Snowflake, with a set of out-of-the-box distributed Spatial Datasets and Spatial SQL that efficiently load, process, and analyze large-scale…
With AI workloads on the rise, the demand for Python support on WebAssembly on the Edge has grown rapidly. However, bringing Python to WebAssembly isn'...
I’ve been learning Persian (Farsi) for a while now, and I’m using a bunch of tools for it. The central one is certainly Anki, a spaced repetition app to train memory. I’m creating my own never-ending deck of cards, with different types of content, for different purposes. The most frequent type of cards is grammar…
What is Typed Python? Why is it important for Python developers today? How to can you get started?
In .NET 9 we enabled DATAS by default. But .NET 9 is not an LTS release so for many people they will be getting DATAS for the first time…
Tracing Rust AtomicU64::fetch_max from macro expansion and rustc intrinsics through LLVM atomicrmw umax down to the final x86-64 CAS loop.
This post shares the local optima Manus arrived at through our own "SGD". If you're building your own AI agent, we hope these principles help you converge faster.
Making vector search fast, memory-efficient, and natural in SQLite.
Over two years ago, in one of my first public talks about Ghostty , I shared my vision for libghostty : an embeddable library for any application to embed their own fully functional, modern, and fast terminal emulator. Libghostty is finally starting to take shape, and I'm excited to share more details about my plans…
Alex Moon is an Australian-British software engineer and artist based in the North East of England.
Last week I had the pleasure of attending RustForge in Wellington, New Zealand. I gave a talk titled “Wild performance tricks”. You can watch a recording of my talk . If you’d prefer to read rather than watch, the rest of this post will cover more or less the same material. The talk shows some linker benchmarks, which…
Adventures using AI agents, especially Claude Code, and MCP Servers
