Reverse Engineering the iPod Classic's Undocumented Mikey Chip
My iPod Classic (7th gen) runs Rockbox, and I love almost everything about that arrangement. But the inline remote on Apple’s wired earbuds (the center play/pause button and the volume clicker) did nothing. Never has, for anyone running Rockbox on this family of iPods. ``` /* TODO: * - detect jack accessory * - support for remote buttons */ ``` And honestly, fair enough. Rockbox on this iPod exists because volunteers reverse engineered Apple hardware with zero documentation, for free, since January 2011. Music, clickwheel, recording, all of it figured out the hard way.…

The UV index is not the warm sensation of sunlight on bare skinWhy sunburn risk and how hot the sun feels on your skin diverge—backed by numbers.
A clear, numbers-first essay explaining why the warmth of sunlight is a poor proxy for UV-B sunburn risk: cloudy cool days can still burn, and scorching morning heat may not, once you separate infrared heating from the UV index.

Reflections on 1,000 Days of Math
I finally hit 1,000 days of doing math daily! Early on in my journey I was a lot more aggressive with my XP targets, but settled into a low-volume rhythm as my goals evolved. I worked from MF1 (Math Foundations 1, lowest level) into MF3, then about halfway through MF3 I started M4ML (Mathematics for Machine Learning). ### Self-induced friction But it got really hard and my progress started to slow as lessons took longer, which was problematic because I was trying to limit my math time to <20m/day. That may have worked fine, but I really screwed myself by relying on…

How to write an effective software design document
Michael Lynch draws on experience writing design documents at Google, Microsoft, and his own companies to explain when to write one, how much to invest in it, and what to include. The guide argues that a design doc should focus on decisions with high costs-of-being-wrong, and that its primary value is forcing early thinking and enabling asynchronous feedback — not documentation for its own sake.

Lotus Notes and the dangers of starting from scratchYou either loved it, or were using it wrong.
Matthew Guay traces how Lotus Notes — which launched in 1989 with encryption, rich text, file attachments, and a synced database before any of those features existed in standard email — was eventually defeated not by being worse than competitors but by being too unfamiliar. The essay is a history of a product so far ahead of its time that its interface became its downfall.
