By Nat Torkington September 4, 2020 • 1 minute read

Inside the Digital Pregnancy Test — … is a paper pregnancy test and watch-battery-powered microcontroller connected to three LEDs, a photo-cell, and an LCD display. That (8-bit) microcontroller runs at 4MHz, almost as fast as an IBM PC did.
The Incredible Proof Machine — Fun game (modelled on The Incredible Machine from the 90s) that teaches logic.
Make Interfaces Hard to Misuse — Don’t push the responsibility of maintaining invariants required by your class on to its callers. Excellent advice.
ArangoDB — a scalable open-source multi-model database natively supporting graph, document and search. All supported data models & access patterns can be comnbined in queries allowing for maximal flexibility.
