Distributed Locks
29+ min ago (110+ words) One-liner: A distributed lock ensures that only one node in a cluster can perform a critical operation at a time — preventing race conditions across services. In a single-server world, a mutex or semaphore handles concurrency. But in distributed systems: Classic…...
Three things that bit us moving a document scanner fully into the browser
33+ min ago (596+ words) I work on LensUp, which does exactly that — the whole pipeline runs in the tab, and files are never uploaded. Disclosure up front: it's our tool, and this post is about the parts that were harder than the pipeline itself....

Your First AWS Production Architecture: From a Simple Application to a Scalable System

Designing a deterministic browser-side photo analysis flow
1+ hour, 22+ min ago (196+ words) While building a small browser-based facial-proportion tool, I found that a few engineering choices matter more than adding another model. The pipeline starts with 478 detected facial landmarks and derives four displayed proportions: harmony, symmetry, eye area, and jawline. The important…...
I built a radio station with one listener, and it runs in a terminal
58+ min ago (638+ words) The film above is 86 seconds, and the middle of it is a real on-air moment. There is a longer unedited recording at the top of the repo README. Watch either first, with the sound on. The rest of this post…...
