#1Thoughts and Feelings Around Claude Design

Anthropic's Claude Design takes a code-first approach to UI design, positioning itself as a direct threat to Figma's dominance. The author argues that Figma's proprietary format locked it out of LLM training data, and as AI makes code easier for designers to write, the source of truth will migrate from design files back to code. The piece predicts Figma is facing its own "Sketch moment" — the same displacement it once inflicted on its predecessor.

#2College Instructor Turns to Typewriters to Curb AI-Written Work

A Cornell German language professor now brings manual typewriters to class, forcing students to write without spell-check, translation tools, or AI assistance. The "analog assignments" eliminate digital distractions and encourage deliberate, slow thinking — part of a broader trend of educators reverting to pen-and-paper exams and oral assessments to counter AI-generated submissions. Students report deeper engagement when they can't simply delete and regenerate.

#3Migrating from DigitalOcean to Hetzner

A detailed writeup of a zero-downtime migration from DigitalOcean to Hetzner that slashed monthly infrastructure costs from $1,432 to $233 — saving over $14,000 per year. The author moved 248 GB of MySQL data across 30 databases, 34 Nginx sites, and GitLab Enterprise using MySQL replication as a live sync mechanism and the old server as a reverse proxy during DNS propagation. A practical playbook for any startup watching its burn rate.

#4The Electromechanical Angle Computer Inside the B-52's Star Tracker

Ken Shirriff tears down the Cold War-era mechanical computer that solved trigonometric equations for celestial navigation aboard B-52 bombers. The device used gears, synchros, and motors to physically model the celestial sphere — converting star positions into usable azimuth and altitude readings without digital computation. A fascinating look at the pre-digital engineering that preceded modern computing.

#5State of Kdenlive

The open-source KDE video editor shipped three major releases in 2025, prioritizing stability while adding automatic masking tools and a 300% audio waveform performance improvement. The project saw strong community growth with 38 code contributors and over 11.5 million downloads, though donations declined to under €10,000. Plans include dopesheet implementation and Microsoft Store availability.
