The first thing I do every time I need to learn a new codebase is to start drawing the UML diagram of its classes, and usually give up soon after I started. The process of doing it manually is certainly useful, but now with reflections I figure it would be fun to try to generate it instead.
9 months ago, I took a gander at PG’s guide to Bel . If you haven’t read it, here’s the premise:
Karl Seguin's Blog - A mix of coding and creative writing
This story is about concurrent data structures in the context of Ruby. The goal here is to demonstrate how true parallelism can be achieved with global mutable state (which at the time of writing, is not supported by built-in Ruby primitives).
One story every computing enthusiast should hear is the lesson ofhow loops and tail-recursion are equivalent. We like recursivefunctions because they’re amen...
Death (XIII) Symbolizes significant change, transformation, and endings, rather than literal physical death. Have you ever seen a Number grazing in the f
An "impossible" Ruby bug: Hashes becoming Strings at runtime. 2,700 identical crashes. No corruption. Just objects changing what they are. Deep dive.
Go 1.24 brings generic type aliases, map performance improvements, FIPS 140 compliance and more.
A discussion of how Sorbet's type syntax came to be, the problems it solves, and how it could improve.
The rationale and transition period to moving to the new “core:os”
A computer scientist working in open source towards a more hopeful future.
We are announcing a new Crystal release 1.16.0 with several new features and bug fixes.
“Keep thy airspeed up, lest the earth come from below and smite thee.” - William Kershner
At one level, this question is not very fair, because an answer to it as stated would be that one simply does not use doubly linked lists. They have been popular in introductory computer science lectures because they are a neat way to explain pointers in a data structure that's easy to draw on a whiteboard, but they…
The gophers nested too greedily and too deep.
Stephen Wolfram explains the rich ruliology of lambdas, made particularly significant by their connection to practical computing. Covers basic computations to undecidability to multiway graphs and evaluation strategies.
“Compiler Engineering in Practice” is a blog series intended to pass on wisdom that seemingly every seasoned compiler developer knows, but is not systematically written down in any textbook or online resource. Some (but not much) prior experience with compilers is needed.
A browser with Wasm GC and tail call support is required for this demo. We recommend using either Mozilla Firefox or Google Chrome.
Types in coding projects are good. Don’t be afraid to create them when you need to.
As usual, when a new blog post comes out on blog.golang.org, I’m all eager to read it as soon as possible. The most recent one, Contributors Summit, is a nice write-up on the issues that the Go contributors have been talking about. While reading it, I stumbled upon a sentence that made me write this post. Here is is…
In this post, I talk about my favorite C/C++ pattern involving macros.
After the Graz, Austria February 2025 WG14 Meeting, I am now confident in the final status of the defer TS, and it is now time.
We’ve been relatively quiet over here at the Zig Software Foundation for a few months now and so it’s about time to give y’all an update.
Write an awesome description for your new site here. It will appear in your document head meta (for Google search results) and in your feed.xml site description.

Not just `#[derive(Clone)]`, but all of the standard trait derives are
To assist with job interviews at the NRAO we recently wrote a small “contest” program. Without giving away the details, the crux of the problem is
