Hacking up a fix for the broken AppleTalk kernel module in Linux 5.1 and newer

I bought a couple EdgeStar AP14001HS portable air conditioners in April 2020, since I expect to spend most of the Summer at home. I'm not able to use window A/Cs here, though that would be the obvious choice for efficiency because all the hot parts remain outside.

Unbricking a $2k bike with a $10 Raspberry Pi
A few years ago I splurged on an exercise bike. It’s a pretty expensive item imho, both in upfront and ongoing subscription costs. But I was able to justify it by riding it all the time so that per-ride it wasn’t that expensive. I’m happy to say this was a huge boon for my fitness and it was worth every penny.

Starting a Business Around GPT-3 Is a Bad Idea
(Update 2023-03: I wrote this in 2020 when GPT-3 was highly hyped, but ultimately made only <1% of the splash that the monstrous ChatGPT made 3 years later. If I had to rewrite this today, I’d 1) think more kindly about defensibility, especially through deep product, user experience, and marketing/distribution (see…

Exactly-Once Initialization in Asynchronous Python
A common situation in asyncio Python programs is asynchronous initialization. Some resource must be initialized exactly once before it can be used, but the initialization itself is asynchronous — such as an asyncpg database. Let’s talk about a couple of solutions.

Migrating a 40TB SQL Server Database
Initially, I wasn’t sure whether to write about this migration project, but when I randomly asked if people would be interested, the response was overwhelming. This was a long, kind of boring, very repetitive, and at times incredibly frustrating project, but I learned a lot, and maybe someone else will learn from this…
