NOTE: This is based on, but completely rewritten, from a Twitter post:https://x.com/TheGingerBill/status/1802645945642799423TL;DR: It makes Go feel too "functional" rather than being an unabashed imperative language.I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024)…
With the release of WASI Preview 2, we take a step back and look at why it matters for wasmCloud and the WebAssembly ecosystem.

How great would it be if the solution to most errors you face were in the first place you looked? That’s what the Arch Wiki has been for me: a massive wealth of information and troubleshooting resources to help me navigate the various configuration and installation issues I’ve encountered. Some people claim Arch Linux…
I’ve been learning at least one new programming language a month through Exercism which has been really fun and interesting. I frequently say that “every language you learn teaches you something about all the others you know” and with nearly a dozen under my belt so far I’m starting to worry about the combinatorics of…
The code is a bit "experimental" but it's available in the arena-fixes branch (make sure to enable --features=development if you run it from a Git repo).
A Chess-AI is something every programmer should build at least once and [Sebastian Lague’s](https://www.youtube.com/@SebastianLague) [competition](https://www.youtube.com/watch?v=iScy18pVR58) was the perfect opportunity for me to do so. Constrained to 1024 tokens I wanted to implement an evaluation function similar to…
Engineering deep-dives, product updates, and company news from Tembo — the platform for running coding agents across your stack.

Introducing the autonomy, product, and operations teams.
Design decisions core to JavaScript have caused a multitude of problems for benchmarking. Is there a solution to this?
This month’s PGSQL Phriday #015 topic is about UUIDs, hosted by Lætitia Avrot. Lætitia has called for a debate. No, no, no. I say let’s have an all-out war. A benchmark war. I have deci…
I wrote the analysis of “useless sugar” features of Ruby for two months, and I regret nothing.

As someone who has from time to time written on parsing, and even published some parsing research , I get asked questions about parsing fairly regularly, some of which I’m even capable of answering.
Design, build and integrate your own Domain Specific Language with Lingo.
Then come along! Let’s make a compiler that goes all the way from source to assembly from scratch—no shortcuts!
Build complex state preservation systems for implementing game save systems or custom netcode with Chickensoft's new serialization tools.
Setting up PostgreSQL for tests is crucial for achieving performance and reliability. In this article, I'll explain how to set up PostgreSQL for tests and discuss some common pitfalls to avoid.
Quartz shares the high level design of a Clock interface that closely resembles the functions in the time standard library, and a "real" clock passes through to the standard library in production, while a mock clock gives precise control in testing.
Today I am releasing my raycasting tech demo for the GameBoy Advance. Although it falls short of the goals I set out in the beginning – which included releasing a playable game –, I think there are some lessons worth sharing with the world.
This is the Part 2 of a series. Feel free to read the prequel for more context: Building the fastest Lua interpreter automatically Building a good VM for a dynamic language takes a ton of engineerin
Over the past 6 years or so, I’ve failed each item on “The Turkey Test.” It’s very simple: will your code work properly on a person’s machine in or around th...
SBCL is a Common Lisp implementation, with a performant compiler and support for a wide range of platforms. It has excellent documentation , and even a guide to internals (... this is written towards people who already know a lot about how it works though). This paper about SBCL's fairly unique build process is also…
A Rust object that survives program restart thanks to Rust allocators, systemd's file descriptor store, and syscall memfd_create.
I’m a keen user of Emacs and Org mode for a variety of tasks, including note taking, generating documents for exporting to LaTeX, Word, or html. creating blog posts (notably for this blog, us…
Introduction Large language models are trained on huge datasets of text to learn the relationships and contexts of words within larger documents. These relationships are what allows the model to generate text. Recently I've read concerns about LLMs being trained on copyrighted text and reproducing it. This got me…
Today, we would like to present a lesser-known feature of the Linux kernel. Instead of launching a program from a file system, regardless of whether it's virtual or not, it is also possible to embed a user-space program directly into the kernel image itself and start it from there.
“Print the sum of 50 million ASCII-encoded integers uniformly sampled from [0, 2³¹−1], separated by a single new line and sent to standard input.”
