I built a $5k Raspberry Pi server (yes, it's ridiculous)

When I heard about Radxa's Taco—a Raspberry Pi Compute Module 4-powered NAS/router-in-a-box—I knew what must be done. Load it up with as much SSD storage as I can afford, and see what it can do.

The Nokia N9 Alarm Clock (2014)

I want to talk about the Nokia N9 (2011) alarm clock application because it’s a really nice example of thoughtful, functional design – and because it’s only on the N9, so a lot of people won’t have seen it.
