Rust Is a Scalable Language

In my last post about Zig and Rust, I mentioned that Rust is a scalable language. Let me expand on this a bit.

Partially Matching Zig Enums

A short post about a neat little Zig idiom. Consider your average {sum type, variant, tagged union, enum, alt}:

Hard Mode Rust (2022)

This post is a case study of writing a Rust application using only minimal, artificially constrained API (eg, no dynamic memory allocation). It assumes a fair bit of familiarity with the language.

Static Allocation, Constant Work

Try to fix it one level deeper

I had a productive day today! I did many different and unrelated things, but they all had the same unifying theme:

Can you trust a compiler to optimize your code?

More or less the title this time, but first, a story about SIMD. There are three levels of understanding how SIMD works (well, at least I am level 3 at the moment):

Goroutines are not significantly lighter than threads

Parsing Advances

I find myself writing yet another toy parser, as one does during a Christmas break. It roughly follows Resilient LL Parsing Tutorial. Not because I need resilience, but mostly because I find producing a syntax tree and a collection of diagnostics a more natural fit for the problem than bailing out on the first error.

; Echo “Shell Injection”

This is an introductory article about shell injection, a security vulnerability allowing an attacker to execute arbitrary code on the user's machine. This is a well-studied problem, and there are simple and efficient solutions to it. It's relatively easy to design library API in such a way as to shield the application…
