In praise of the hundred page idea
I prefer a lightweight nonfiction book to a detailed tome. I’m a dilettante of many interests, so my attention for any given topic is more likely to sustain 100 pages than 600. The sweet spot is longer than a longread internet article, but that doesn’t demand a months-long commitment: a 2-3 hour text.

Nurses whose shitty boss is a shitty app
Operating a business is risky: you can't ever be sure how many customers you'll have, or what they'll show up looking for. If you guess wrong, you'll either have too few workers to serve the crowd, or you'll pay workers to stand around and wait for customers. This is true even when your "business" is a "hospital."

The RAM Myth
The RAM myth is a belief that modern computer memory resembles perfect random-access memory. Cache is seen as an optimization for small data: if it fits in L2, it’s going to be processed faster; if it doesn’t, there’s nothing we can do. Most likely, you believe that code like this is the fastest way to shard data (I’m…

Java in the Small
Java has many features that make it well suited for large, long-lasting projects. But I find it surprisingly good for small tasks as well. Recent language features make it even better. The killer features are compile-time typing and great tool support.

How we centralized and structured error handling in Golang
Handling errors in Go is simple and flexible – yet no structure! It’s supposed to be simple, right? Just return an error , wrapped with a message, and move on. Well, that simplicity quickly turns into chaotic as our codebase grows with more packages, more developers, and more “quick fixes” that stay there forever…

Running NetBSD on IBM ThinkPad 380Z
Launched in 1998, the 380Z was one very fine ThinkPad. It was the last ThinkPad to come in the classic bulky and rectangular form factor. It was also one of the first to feature a huge 13.3" TFT display, powerful 233MHz Pentium II, and whopping 160 megs of RAM.
