I have a couple of ideas about learning programming languages. The first is that we do it wrong. I’m sure you’ve experienced this. You try learning a new language and can’t quite see how it all works. Why do I use this syntax here and some other syntax over here? We get frustrated by all the weird bits and go back to…
EDIT: As pointed out in the Rust reddit thread, the Rust version can be modified to run faster due to a suble difference between ..=z and ..(z+1). I’ve updated the measurements with rustc0 be…
Recently, I got yet another nice email from a “talent sourcing specialist” asking me if I’d like to work for their company. This one stood out from the usual blockchain recruiting spam by actually looking at this blog. And they told me their expectations were lowered by the front matter stating that I’m currently…
The CallerArgumentExpression has been discussed for years, it was supposed to a part of C# 8.0 but got delayed. Finally this month it is delivered along with C# 10 and .NET 6. …
The rationale and transition period to moving to the new “core:os”
Functional programming explained for the pragmatic programmer. Part 1. An introduction.
I’ve been programming in Clojure for a long time, but I haven’t been using transducers much. I learned to mechanically transform (into [] (map f coll)) to (into [] (map f) coll) for a slight performance gain, but not much beyond that. Recently, however, I’ve found myself refactoring transducers-based code at work…
I had a really enlightening talk with Daniel Slutsky this week (who is an exceptional data scientist, software engineer, and community organizer I highly…
By all accounts, TypeScript has been a big success for Microsoft. I've seen loads of people sparkle with joy from dousing JavaScript with explicit types that can be checked by a compiler. But I've never been a fan. Not after giving it five minutes, not after giving it five years. So it's with great pleasure that I can…
I learned Java and C at school, I learned Python by myself and it was a relief. After 8 years working and doing side projects in Python and JavaScript (mostly web dev, Django/Flask/AngularJS/Vuejs), I am not satisfied anymore by the overall experience so I’m making Common Lisp my language of choice.I am not here…
In previous posts, we covered the most popular implicit use cases. What is left to complete the picture is the mechanics of implicits itself.
Over the last few weeks, I’ve been devoting my free time to fleshing out the theory behind non-lexical lifetimes (NLL). I think I’ve arrived at a pretty good point and I plan to write various posts talking about it. Before getting into the details, though, I wanted to start out with a post that lays out roughly how…
I just heard that core.typed is ready for production. Which is great timing because I'm working with a new team and they like types.

Hello Rustaceans! Sometimes, good things come in many. For example: birthdays! 🎉 As it just so happens, we have 3 big things to celebrate: It's the 10th anniversary of Florian publicly posting his first Rust code on September 28th, 2013! Ferrous...
OCaml 4.03 is branched and a first release candidate is imminent, so it seems like a good time to take stock of what’s coming.
We are announcing a new Crystal release 1.16.0 with several new features and bug fixes.
Does this Go snippet compile, and if not, why?
This tutorial will show you how to write assembly language programs on the x86-64 architecture.

The introductory post for this book, unexpectedly, received quite a lot of attention, which is nice since it prompted some questions, and on...
“Keep thy airspeed up, lest the earth come from below and smite thee.” - William Kershner
C interpreters are a common language implementation technique and the basis for the reference implementations of languages such as Lua, Ruby, and Python. Unfortunately, C interpreters are slow, especially compared to language implementations powered by JIT compilers. In this post I’m going to show that it is possible…
