👋🏼 This is part of series on concurrency, parallelism and asynchronous programming in Ruby. It’s a deep dive, so it’s divided into 12 main parts: Your Ruby programs are always multi-threaded: Part 1 Your Ruby programs are always multi-threaded: Part 2 Consistent, request-local state Ruby methods are colorless The…
Not doing anything with it is exactly the point.

(Discussion on HackerNews)
It has been three days. The room is cold and dark, but your screens are blinding. You feel disoriented as you come in and out of dissociative episodes. Now and again, you laugh, to no accompaniment. Why are you here? Was this your fault?
Good development practices for modern Python
I’ve noticed a small but interesting trend in the programming languages space. I’m not sure how novel it is, but this pattern, which I’ll refer to as “biphasic programming,” is characterized by languages and frameworks that enable identical syntax to express computations executed in two distinct phases or environments…
With Perl 5.36.0 just around the corner, we thought that this is a good time to clarify plans for the future of the Perl programming language. We realised that the future was hammered out in a number of steps, across several months. This meant that there hasn't been a single statement we could refer people to. This…
Pattern matching is a pervasive and powerful tool in Elixir. This isn't too surprising if you know a little about the history of Elixir's parent language, Erlang. Erlang was originally inspired by and written in Prolog, a logic programming language where pattern matching has first-class support. In
C is beautiful yet full of horrors. Here's to uncovering its hidden depths.
Recently, we had a discussion in our team about undefined behaviour (UB) in C. For those unfamiliar: We say that a program has undefined behaviour when we write code where the language specification doesn't define what should happen during execution. That means compilers can do whatever they like if they encounter…
(I've been editing this post on and off for almost a year. I'm not really happy with it, but I suspect I never will be.)
No, I’ve not gone to the click-baiters (“10 tips that will change your life today!!!”), but I chose to limit myself to just 10 so that I don’t pull what is considered a R…

It’s more than rails!
I was talking with someone today that really really wanted the sqrtps to be used in some code they were writing. And because of a quirk with clang (still there as of clang 18.1.0), if you happened to use -ffast-math clang would butcher the use of the intrinsic. So for the code: __m128 test(const __m128 vec) { return…
Code reflection, an enhancement to Java reflection, enables access to symbolic representations of Java code in method and lambda expressions. “Symbolic representations of Java code” may seem like a fancy term, but its easily demystified. It’s a model of Java code where the code of a method or lambda expressions is…
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)…
Anyone trying to make a new mainstream language is completely insane, unless they're backed by a large corporation. 0
Haskell is a programming language invented sometime in the 20th century by Scottish logicians as a prank. ¹ Fifteen years or so ago, for reasons I can no longer remotely recall, I started learning Haskell. Now, I have finally written a useful program in Haskell, and I am pretty sure I can do it again, if I ever need…
In 2011, to celebrate the 150th anniversary of MIT, the Boston Globe made a list of the most important innovations developed there. They asked me to explain the importance of SICP, and this is what I sent them:
A C program that writes "hello, world!" to the console using inline assembly instead of standard library functions, demonstrating direct system call invocation.
How Zig's allocators can help manage memory and improve performance
How a 10 year old design choice for Swift’s type checker still haunts us to this day
This post lays out a 4-part roadmap for the borrow checker that I call “the borrow checker within”. These changes are meant to help Rust become a better version of itself, enabling patterns of code which feel like they fit within Rust’s spirit , but run afoul of the letter of its law . I feel fairly comfortable with…
Elixir v1.17 released: set-theoretic data types, calendar durations, and Erlang/OTP 27 support.
Swift is a general-purpose programming language built using a modern approach to safety, performance, and software design patterns.
