Gooey rubber that's slowly ruining old hard drives
As part of my work toward an upcoming post about a lost piece of very obscure Mac history that has finally been found, I’ve been playing around with old Apple-branded SCSI hard drives made by Quantum and Conner in the 1990s. What I’m about to describe is already common knowledge in the vintage computing world, but I…

Hallucinations in code are the least dangerous form of LLM mistakes

Towards a test suite for TOTP codes
Because I'm a massive nerd, I actually try to read specification documents. As I've ranted ad nauseam before, the current TOTP spec is irresponsibly obsolete. The three major implementations of the spec - Google, Apple, and Yubico - all subtly disagree on how it should be implemented. Every other MFA app has their own…

Knowing CSS is mastery to front end development
There are countless articles why developers should not focus on Frameworks too much and instead learn to understand the underlying languages.

Xcode constantly phones home
Building StopTheMadness Pro in Xcode is usually very fast, because my project doesn't use any Swift. It's a combination of Objective-C, which compiles much more quickly than Swift, and JavaScript, which doesn't need to be compiled.
