This one is going to be a quick one as there wasn't anything new discovered. In fact, I feel quite dumb. This is really a tale of " Do your research before acting and know what your goal is, " as you'll end up saving yourself a lot of time. Nobody likes throwing away work they've done either, and there could be…

10 implementations of handwritten matrix multiplication: from plain C and Swift through to Metal
I spent 100 hours vibecoding an app and it's not as simple as people say.
This somewhat widely cited post (I keep seeing it cited, anyway) suggests that dynamic languages and/or languages that represent things more concisely are more token efficient. It seems to be cited enough that LLM search results agree. For example, when I searched for "dynamic vs static language token cost" (no…
Today, we will meet a spiky-haired nerd named Corey Dumm, who normally lives within Markdown code fences. We will get to know him a bit, smile with him when his fences hold and weep quietly when misfortune strikes.
Bun 1.4 rewrites Bun in Rust, ships built-in headless browser automation (Bun.WebView), Bun.Image, Bun.markdown, JSON5, JSONL, Terminal and cron APIs, Node.js 26.3.0 compatibility with 1,517 newly passing tests, parallel test and run, Windows ARM64, and an opt-in global virtual store for up to 7× faster installs.
A common refrain is that Emacs is an operating system (OS). This isn’t true, but what invites comparison to an OS is its ability to orchestrate applications and utilities above the OS kernel...
An accidentally fast variable-length integer encoding
Go 1.26 made Green Tea the default GC. We observe its cache-friendliness with perf, visualize the heap to see how Go allocates, and poke at a sparse-page problem a non-moving collector like Go's struggles with.
WASI 0.3 is official, and async is now native to WebAssembly Components. The WASI Subgroup voted to ratify WASI 0.3.0, rebasing WASI onto the WebAssembly Component Model’s async primitives. The 0.3.0 specification is now stable, and runt...
every regex engine that promises linear time breaks that promise the moment you ask for all matches. the problem has been there since the 70s, hiding in the iteration loop.
Once I wrote users.select { |u| u.admin? }.map(&:email) and realized I’d written Lisp.
Learn how to use PostgreSQL as a Dead Letter Queue (DLQ) for event-driven systems. Case study from Wayfair showing how to handle failures in Kafka consumers with PostgreSQL.
This is a catalog of things UNIX-like/POSIX-compliant operating systems can do atomically, making them useful as building blocks for thread-safe and multi-process-safe programs without mutexes or read/write locks. The list is by no means exhaustive and I expect it to be updated frequently for the foreseeable future.
Building a SPA (Single-page Application) is a complex puzzle: a JavaScript framework that draws the view, an API serving JSON, and 2 independent…
I gave Claude Fable 5 and GPT-5.6 Sol the same unpublished NP-hard optimization problem, with and without their native /goal mode. Fable 5 is a beast; /goal is not a game changer.
Better than regex!
Thanks to 227 contributors, 817 pull requests, community reviewers, and our generous donors, we're happy to announce the Bevy 0.20 release on crates.i…
The official home of the Erlang Programming Language
The async/await saga is a story where each chapter solves the previous chapter's worst problem while introducing new structural costs. The sequential syntax that made async code readable also obscures the thing that matters: which operations actually depend on each other.
However recently it added a killer feature: generated columns . (This was added in 3.31.0, released 2020-01-22.)
Today’s coding benchmarks have established that models can write correct code, but the question we should really be asking is: can models actually write…
An Introduction to File Formats and ImHex by Reverse Engineering FEZ's Save File Format
This post details how Factorio's random number generation works, how it can be reversed and how I used that knowledge to predict and manipulate the RNG with pure in‑game mechanics.
I read this post “Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases [from C++ to Rust]. Our North Star is ‘1 engineer, 1 month, 1 million lines of code.” and it got me curious, how difficult is it really?
GPU code can now use Rust's standard library. We share the implementation approach and what this unlocks for GPU programming.
