One of the things I like to do is compare how different languages solve the same problem — especially when they end up having very different approaches. It’s always educational. In this case, a bunch of us have been working hard on trying to get reflection — a really transformative language feature — into C++26…
A long time ago, I wrote a memoization library for Ruby. It was not easy, but I learned a great deal in the process. In this article, I am share these learnings and showing you how deep the memoization rabbit hole goes.
Not sure if your compilers have matching ABIs? Then put them through the ultimate compatibility crucible and pair them up on a shift at The ABI Café! Find out if your one true pairing fastcalls for each other or are just another slowburn disaster. (Maid outfits optional but recommended.)
The official home of the Erlang Programming Language
This post intends to provide a brief overview of the algorithm described in Luc Maranget’s “ Compiling Pattern Matching to Good Decision Trees ”.
The following is a loose collection of thoughts that came up while porting unsafe-libyaml to safe, idiomatic Rust, which may be useful to someone else who is considering "rewriting it in Rust", as the ancient journeyman prayer goes.
In my off time (and my on time, for that matter) I've been working on this quirky thing I've called Scinamalink (sounds like 'skinamarink'). Scinamalink lets customers send Magic login links to their users with a single REST API call. If you don't know what a magic
Some C++ folk seem to think so, but they're wrong!
I was just chatting with Ben Titzer on Twitter about control flow in his Virgil language (which is cool and you should definitely check ...
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…
This will be the first in a series of posts describing different design decisions made writing two Rust crates:

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…
OCaml's let … = … in … is very confusing. When nested, you can't tell how it's nested.

Or: The Most Expensive Linked List I’ve Ever Written
Scheme to the Spec is a series on the more complex, often overlooked aspects of programming language implementation.
Zig is a general-purpose programming language and toolchain for maintaining robust , optimal , and reusable software.
In my last post I floated the idea of writing a slow, edit-prone shell script instead as a self-rebuilding C program.
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++. Or, for that…
Updated (2014-10-24): If you find this article interesting, you may be interested in the follow-up article on an editor for composed programs .
We are announcing a new Crystal release with several new features and bug fixes.
In the early-to-mid 2010s, there was a renaissance in languages exploring new ways of doing concurrency. In the midst of this renaissance, one abstraction for achieving concurrent operations that was developed was the “future” or “promise” abstraction, which represented a unit of work that will maybe eventually…
Next-gen compile-time-checked builder generator, named function's arguments, and more!
A deep dive into Rust’s vec::Drain and its Drop implementation as an example of how ownership prevents subtle bugs—memory and otherwise!
