4B If Statements
I recently stumbled upon this screenshot while researching social media on the train. Of course, it was followed by a cascade of spiteful comments, criticizing this fresh programmer’s attempt to solve a classical problem in computer science. The modulus operation.

BASIC was not just a programming language
BASIC is often dismissed as an inferior language compared to its successors. Common complaints are its use of line numbers, its heavy reliance on GOTO for execution flow, and its lack of a stack for local variables. What many critics overlook is that at the time of its use (during the first wave of home computers)…

Xmas.c (1988)
The second block has more real work going on. If the character stored in the variable _ does not match the first character of the string a , the code recurses in such a way that this same block of code will again be entered. That is, t=-65 forces a return to the if (t < -50) block. The recursion steps through string a…

Understanding every byte in a WASM module
In my last post, we explored how to build WASM modules, both with and without WASI support, using Clang. In a comment on Reddit, it was mentioned that much of the setup I walked through in that post could be avoided by just leveraging Zig’s WASI supprt. This is a great point, and I would recommend doing the same. The…

Memory safety is necessary, not sufficient
TL;DR: I think that a focus on memory safe languages (MSLs) versus non memory-safe languages is a bit of a red herring. The actual distinction is slightly…

Do you really need foreign keys?
Foreign keys are a bit like that well-intentioned friend who insists on double-checking everything you do. They’re often recommended as a must-have for enforcing referential integrity checks in your database.

Simulating fluids, fire, and smoke in real-time
Fire is an interesting graphics problem. Past approaches generally faked it. For example, Lord of the Rings used sprites with lots and lots of smoke (the fluid sim was too expensive at the time, even for movies). Real-time applications like video games have pretty much exclusively used non-physical approaches.

The day I started believing in unit tests
Right after getting my degree, I was lucky to be hired into a small but decent R&D department as an embedded software engineer. My first task was to create a Unit Test project and have it run in our build pipeline after compilation. I was not particularly excited about this task, it seemed like busywork to me. I…

Development slowness in big and legacy applications
Software companies come in many sizes. There are small startups, medium-sized companies, and huge enterprises. As you might expect, startups are usually lean and fast. Big companies that develop large applications move much more slowly. Those might be systems developed for many years or decades by hundreds of…
