All in with Nuitka
After more than 10 years of working on the Python compiler Nuitka, and at the age of 50, I have finally decided to take the plunge. My projects “Nuitka” and “Nuitka commercial” are now my day job , and I quit my work in the Air Traffic Community, after working on ARTAS (a software to create an Air Situation Picture…

MiniRust
I have been thinking about the semantics of Rust – as in, the intended behavior of Rust programs when executed, in particular those containing unsafe code – a lot. Probably too much. But al...

Async Rust doesn't have to be hard
An article titled Rust Is Hard, Or: The Misery of Mainstream Programming came out today and it's getting a lot of attention. I have a feeling that it's viewed in a wrong context, so I'd like to comment on the issue raised there.

So, I’ve been working on a programming language in my spare time for over a year now. I’ll save you the details but it’s meant to be a minimal, easy-to-learn language for beginners. This year for the Advent of Code, I set myself a challenge; complete every day’s challenge using only my programming language.

OpenBSD has two new C compilers: chibicc and kefir
In my never ending quest to have oksh support every C compiler in existence, I have ported two more C compilers to OpenBSD . They are chibicc and kefir. As always, let's review them and at the end I'll have links to unofficial ports so that you can play around with these C compilers.

How safe is Zig?
I keep seeing discussions that equate zig's level of memory safety with c (or occasionally with rust!). Neither is particularly accurate. This is an attempt at a more detailed breakdown.

What Happened to Perl 7?
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…

Why would anyone need JavaScript generator functions?
You can go a long time as a JavaScript developer without ever feeling the need for generators. Hence, it’s natural to wonder: What are they good for? Why would you ever need one? What’s the point? But generators can do some neat tricks. And they may even change the way you approach certain problems.

I wrote the least-C C program I could
As a fun afternoon challenge, I decided to write a C program that looked nothing like C. Not necessarily obfuscated, though there is a competition for that if you are so inclined.
