Asynchronous code does not require the rest of your code to be asynchronous. I can’t say the same for blocking code.

Joseph Gentle wrote a post on how he wants Rust to change. I am already working on that.
In the first half of 2024, Ruby LSP has seen significant enhancements, particularly in the area of code navigation, thanks to the advancement of its indexer. In this post, we’ll dive into the major code navigation enhancements that have been made to Ruby LSP. We’ll also touch on some experimental features that are on…
Systems engineering, Rust development, and Unix infrastructure by Till Wegmüller (@toasterson)
The missing introduction.
NSCopyObject is a very old Foundation function – pre-dating Mac OS X entirely; from the NeXT era – that was originally basically just memcpy , but now it’s complicated. A lot more complicated.
Using Elixir instead of Python or Ruby for shell scripting.
What Ruby’s top-level methods actually are, who they belong to and how they are namespaced
A post by Eshel Yaron with details and advice about a long standing arbitrary code execution vulnerability in Emacs
Tuesday, January 28, 2003 0xCAFEBABE & 0xFEEDFACE Recently, the origin of the magic numbers of 0xCAFEBABE and 0xFEEDFACE came up in an email conversation between a number of ex-NeXT folks. Specifically, someone asked what the origin of the two magic numbers were in the context of mach-o file formats and why had Java…
Why are database DELETEs complex and inefficient? Uncover challenges from physical data removal to autovacuum, and find strategies for managing large deletions.
An english translation of Edsger W. Dijkstra's interview on Dutch TV.
We’re excited to announce the release of Zulip Server 9.0, containing hundreds of new features and bug fixes! Zulip is an open-source team chat application designed for seamless remote and hybrid work. With conversations organized by topic, Zulip is ideal for both live and asynchronous communication. …
This set of slides sketches out the implementation of Hell , in technical detail. I do tend to switch between the slides, old code, and the present code, so bear with me. It's more about the ideas. If you want to see a complete implementation, the complete implementation of Hell is one file , which you can look…
Looking beyond the hype and explaining why microservices should nearly become extinct.
I recently stumbled upon a blog post by Alejandra González (a.k.a @blyxyas) that seeks to compress a tic-tac-toe game state into as few bits as possible. She arrived at a solution in 18 bits. This got me thinking, can we do better?
Support for Vite is now stable in Remix v2.7.
The basics condensed into one very large document
GC within a function doesn't work how I expected
I needed to log when a light switched on and off during the night as part of debugging an oddly behaving movement sensor. To do that I built...
This morning, I came accross Cameron Sun’s Probabilistic Tic-Tac-Toe on HN . However, the comments were disappointing, with people proposing probabilistic models, linear programming, minimax algorithms, and heuristic evaluations to develop AI approaches for the game, none of which quite correct. In this post, I’ll…
