Browsers barely care what HTTP status code your web pages are served with
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of.

Hands-Free Coding (2020)
Earlier this year, I lost the ability to use a keyboard and mouse for extended periods. Fortunately, this wasn't as catastrophic as it sounds! This article chronicles my experience using adaptive tools like dictation and eye-tracking as my primary mechanisms for writing code.

Interesting things about the Lua interpreter (2020)
The Lua programming language is unusual among its peers. It’s a dynamically typed, scripting language with a really small core (100-200kB), but runs efficiently, has far simpler semantics than other similar languages, and is just as old as the giants like JavaScript, Python, and Ruby – first made in a research lab…

Why Kakoune
Recently I’ve stumbled upon a video about Kakoune, a code editor: Idiot user tries to use Kakoune (for notes? Also Helix?). Funnily enough, I was mentioned in this video, which was a surprise, and made me laugh for quite a while: Let’s go back to the official plugins page.

Nix journey part 0: Learning and reference materials
In this series I'll be documenting my journey learning Nix and this first installment is more of a prequel. A common complaint when learning Nix is that the documentation "is not good", and I think what people mean by that is that the documentation is spread across several sources which may or may not be easy to find…

An easy-to-implement, arena-friendly hash map
My last article had tips for for arena allocation . This next article demonstrates a technique for building bespoke hash maps that compose nicely with arena allocation. In addition, they’re fast, simple, and automatically scale to any problem that could reasonably be solved with an in-memory hash map. To avoid…

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)…
