Forth is uncommonly used to teach programming to kids. Scripting languages like Python and visual environments like Scratch are far more popular options. But when I got the opportunity to introduce middle and high school students to programming, I chose the stack-oriented concatenative language from 1970. I was…

Read this Tcl/Tk hands-up/primer to find out how the open-source Command Tool Language toolkit can help you develop cross-plaform tools for Windows, Linux, macOS and even Android.
Compilers have a hard time optimizing floating point math. Rust has a new API to fix this.
Join me as I update a project through 10 years of Unity editors. Along the way I will talk about my process, Unity tips and tricks, and the tech changes of Unity Engine - several of which I observed firsthand while working at Unity.
A sourced history of ThinkPad from IBM's 1992 700C to Lenovo's 2026 AI workstations: TrackPoint, keyboards, X-series, T-series and P-series.
What makes BEAM and OTP different from async/await, threads, and actors. Process isolation, supervisors, and why Erlang's model keeps winning 40 years later.
A new Northwestern University study in humans and mice has discovered a novel biomarker of schizophrenia that could also serve as a new drug candidate to treat the cognitive symptoms of the disorder. Schizophrenia affects .5% of the world’s population, including about two million people in the U.S.
Welcome to LTT Labs - your go-to destination for all things tech. Explore comprehensive test results, insightful commentary, and the latest analysis in hardware.
A long, long time ago, in a land free of binary exploit mitigations, when Unix still roamed the Earth, there lived a pre-authentication Telnetd vulnerability. In fact, this vulnerability was born so long ago (way back in 1994) that it may even be older than you. To put the
Data migrations are a critical part of the database lifecycle, and are sometimes necessary for version upgrades, sharding, or moving to a new platform. In many cases, migrations are painful and error-prone. In this article, we walk through how migrations are performed at PlanetScale, and offer advice on how to improve…
A deep dive into Emacs's widget library: what it does well, where it falls apart, and a step-by-step case study of building a table widget with editable cells. Includes working code and hard-won lessons about state management, layout hacks, and cursor position preservation.
Every NanoClaw agent will access external services through OneCLI's Agent Vault, a gateway that handles credential injection, access policies, and approvals so agents never hold raw API keys.
So I was optimizing a domain-specific compressor the other day, as one does. One important problem was chunking the input string and optimally choosing the most compact encoding for each chunk (different encodings compress different characters better, so where to split is not immediately obvious). The previous post…
I’ve been taking photos of benches for years. Sometimes on purpose because I find them intriguing and I have an thing for objects designed for people but without anybody using them, sometimes just because they were there next to my subject. Last year, looking at these photographs, I noticed something I didn’t know…
Why ast.walk when you can ast.sprint? How we made Python AST traversal 220x faster while building a custom linter for Reflex's AI code generation.
A step-by-step guide to modern texture memory layout
We pointed our AI audit pipeline at Cloudflare's CIRCL experimental cryptography library and confirmed seven real bugs, from a critical float64 precision loss in threshold RSA to a complete access-control break in attribute-based encryption. All seven are now fixed upstream. This is the first post in a series on bugs…
As my cat woke me up way too early for a Saturday morning, I decided to put all this extra time (and my ChatGPT Pro subscription) into good use and generated a QR-code generator for PostgreSQL, written as a single pure SQL statement. No external libraries or Postgres extension installation needed! The pqr.sql example…
I'm happy to announce the general availability of watgo - the W eb A ssembly T oolkit for G o. This project is similar to wabt (C++) or wasm-tools (Rust), but in pure, zero-dependency Go.
By Robert Smith mine is a brand new IDE for Coalton and Common Lisp, built from the ground up with one purpose: To make Coalton and Common Lisp easier and more accessible to the programming world. TL;DR? Go to mine's homepage with downloads for Windows/macOS/Linux. mine is a complete, single-download application that…
In my previous blog post I talked about how I bought a Blu-ray drive and a couple of M-Discs to use it for long-term archival backups.
A major ECFR poll finds the European public, in a time of rupture, thinking differently and questioning old assumptions. It reveals new political space availabl
Modern PC games make you install a ring-0 anti-cheat driver you can't audit.
The letters we write with are not abstract shapes. They are the result of a millennia-long process of evolution. A baton, passed down through a hundred generations, and carrying with it the influence of every one of them.
A bespoke software revolution? I don't buy it. It'll exist. It already exists. Small consultants and big consulting firms have made custom software for years. It almost always sucks. It’s bloated, confusing, and because the client pays, it’s built in all the wrong ways. Who’s excited about bespoke software? Software…
My wife and I have been looking for an app to track things like habits, hobbies, and when we last did certain chores.To be honest there are probably hundreds of different habit trackers on the App Store. Next to todo list apps they are supposed to be the easiest apps to create so it is not really that surprising there…
