Software designers, not engineers: An interview from alternative universe
How very different the world of software is in an alternative universe which has software designers rather than software engineers? In this interview, we look at a range of topics from software design sketching to software designer education, as well as the way in which software designers reshape any problem they are…

Zig: Upcoming release postponed two more weeks and lacks async functions
I’ve been saying the upcoming 0.11.0 release of Zig would have async/await/suspend/resume for 9 months now. You can probably find 10 different places where I promised in writing or in front of a camera that this next release would have this feature.

J Notation as a Tool of Thought
Kenneth Iverson’s 1964 language, APL, won him the Turing Award. His award lecture, Notation as a Tool of Thought, argued that better notations would lead people to deeper insights about mathematics. He provided a number of examples ranging across linear algebra, arithmetic, probability, and logic. Unfortunately, most…

Using Zig to Unit Test a C Application
Zig is a new, independently developed low-level programming language. It’s a modern reimagining of C that attempts to retain C’s performance while embracing improvements from the last 30 years of tooling and language design. Zig makes calling into C code easier than any other language I’ve used. Zig also treats unit…

Undefined vs. Unsafe in Rust

If you didn’t run code written by assholes, your machine wouldn’t boot
This was passed on to me by Ben Elliston, ex-gcc hacker and good guy. Amusing in context, but the corollary is that working on free software means you'll encounter such people. You may have to work with them. You may have to argue with them (and they may be right). Quite some time ago I was horrified by the private…

Runtime code generation and execution in Go
Disclaimer: I won’t expand on why/when you want to do this kind of hack, and you should not do this unless you know exactly what you are doing. Everything I talk about here is completely unsafe and might not be accurate for the future Go versions. This is not a recommendation, but more of a fun story.

Hacking Coroutines into C
A while ago, I was part of a team developing embedded software. The software was deeply rooted in state machines - dozens of them—spread across multiple functions. While this architecture is common in embedded development, especially for systems without an operating system, I started to question: Is this really the…
