Argon2id vs PBKDF2: Why We Upgraded LockedPages
PBKDF2 at 600,000 iterations takes 150 ms on a modern CPU — and 2 ms on a GPU. Argon2id is the OWASP #1 recommendation for a reason. Here is the full migration story.

Adaptive Difficulty in Match-3: How We Built the AI System
Series: Galaxy Diamond Devlog · Part 1
Naive difficulty curves treat every player identically and fail them both. This is how we built an adaptive AI system that reads momentum and adjusts invisibly — and why the design turned out harder than the implementation.

Clip Trimmer: From 0 to 55 Tests in One Month
Building a Python CLI that automates face crop, punch zoom, and word-level captions. The 55 tests are a catalogue of things that broke silently — FFmpeg, Whisper drift, ASS format edge cases.

.apx Format: The Design Principles Behind a Smarter Archive
Standard archive formats treat files as flat lists. The .apx format was designed around different principles — content-awareness, deduplication, and searchability. This is why the distinction matters and what it enables.
