After 10 years of on-and-off work, I’m releasing a full reverse-engineering of the 1998 Ultima Online demo server: https://github.com/draxinar/ouo . About 5,000 functions disassembled from MSVC x86 and translated into portable C99, with each function compared instruction-by-instruction against the binary.
Introducing noq: n0's QUIC implementation
I've built the same webhook consumer three times at three companies. The fourth time, I want a better primitive.
A useful pattern for LLM classification at scale is to let it hallucinate plausible, fake entities. Then resolve to real ones.
A lot of people want to make a website but don’t know where to start or they get stuck. That’s in part because our perception of what websites should be has changed so dramatically over the last 20 years.
On 23 April, Borealis booted in orbit on DPhi Space's ClusterGate-2: a pure-OCaml CCSDS protocol stack with end-to-end-encrypted command and control and post-quantum key rotation. OxCaml is what comes next.
Let's chill just a little bit on the "TLA+ will save AI from itself" narrative
Coherence and the orphan rules are a frequent source of complaints about Rust, and a common topic of language proposals. This post covers most of the existing proposals around coherence and my vision for how we should solve coherence once and for all.
When I first stumbled upon fluid simulations in game dev I was amazed on how good the effect could be. I really wan...
SQLite has evolved far beyond a simple embedded database. Explore modern features like JSON, FTS5, window functions, strict tables, and more.
A tutorial Formal Verification using Lean for cryptographic engineers. Implement and prove correctness of the One-Time pad following a cryptography book.
Understanding large codebase can be incredibly difficult. In this post I walk through how I learn a codebase use turbopack as my case study.
Around 2000 I took an AI course at the University of Guelph. I don’t think I learned too much. We didn’t talk about neural networks, as far as I can remember. My end of term project was, I think, a pathfinding algorithm wearing an AI costume. There were certainly no discussions of transformers. No CUDA. No PyTorch…
Multiplayer has been the single most requested feature for Teardown ever since before its initial release. Synchronizing physics over the network is already known to be hard, and on top of that we have a completely dynamic, destructible world with full modding support. For a long time, we considered the whole idea…
I keep designing physical parts for our robots. Motor mounts, sensor brackets, wheel hubs. Every time, the workflow is the same: open a GUI CAD program, click a
TrueType is a widely used vector font standard for rendering text in web pages, PDFs, operating systems, and applications. Familiar fonts like Helvetica, Garamond, and Monaco are all built on TrueType outlines. The format specifies a hinting interpreter intended to help outlines rasterize faithfully on low-resolution…
A few days ago I wrote about Rewind VM, a deterministic VM where every run of a Nix build is a pure function of its inputs, thread schedule included! I have been using it to find, reproduce and solve numerous race conditions in Nix builds, but it’s been making me feel a little crazy. What is this superpower, and why…
And why you would want to exec a cpio
After 7 years in production, Scarf has reluctantly moved away from Haskell — Avi Press
_posted by Stephen De Gabrielle and John Clements_ We are pleased to announce Racket v9.2 is now available from https://download.racket-lang.org/. As of this release:: The `match` form checks that when non-linear patterns (patterns where the same vari...
This blog post and the companion video both explain an erosion technique I’ve worked on over the past eight months. The video has lots of e...
The LISP curse is often quoted as the reason why so few libraries and reusable components exist for LISP dialects. According to the concept, LISP is so power...
A new analysis from OpenAI reveals issues in SWE-Bench Pro, a popular coding benchmark, raising concerns about reliability and accuracy in evaluating AI models.
around a year ago, we built a regex engine in F# that not only outperformed the ones in dotnet, but went above and beyond competing with every other industrial regex engine on a large set of industry-standard benchmarks. it also supports the full set of boolean operators (union, intersection, complement) and even a…
This article was written by Marco Manino and Alberto Carretero, dqlite team at Canonical. 1. Anatomy of a SQLite bug Recently SQLite published a new version with a fix to a long-standing bug in the way that the Write Ahead Log (WAL) is checkpointed that leads to the corruption of the database. The important aspect […]
When we first announced the transition to Plasma Wayland, one of Martin's slides from stated, "It's done when it's done!"
In this post I discuss the support for union types released in .NET 11, how they're implemented, the choices made, and how to create your own
AI can make implementation cheap while making review and judgment more expensive.
I have come to suspect that to most people thinking is painful. Some of us are addicted to thinking. Some of us find it a necessity. Johnny ...
Celebrating Toit v2.0.0 after more than four years of alpha development.
