From Azure Functions to FreeBSD
Putting FreeBSD’s “power to serve” motto to the test. On Thanksgiving morning, I woke up to one of my web services being unavailable. All HTTP requests failed with a “503 Service unavailable” error.

The AI wildfire is coming. it's going to be painful and healthy

Scala 3 slowed us down?
Is this clickbait? Not really. Is this the fault of the language or the compiler? Definitely not. Rather, it was part of a rushed migration. Sharing the lessons learned in the process.

Java Hello World, LLVM Edition
After exploring Java bytecode in previous years (2022, 2023, 2024), this year we’ll take an unexpected detour for a Java advent: instead of generating Java bytecode, we’ll use Java to build and execute LLVM IR, the intermediate language behind compilers like clang. Using Java’s Foreign Function & Memory (FFM) API…

Eurydice: a Rust to C compiler
Perhaps the greatest surprise of the last two years was, for me, the realization that people not only care about compiling C to Rust (for obvious reasons, such as, ahem, memory safety) – they also care about compiling Rust to C! Wait, what?

Using LLMs at Oxide
Large language models (LLMs) are an indisputable breakthrough of the last five years, potentially profoundly changing the way that we work. As with any extraordinarily powerful tool, LLM use has both promise and peril — and that they are so general-purpose leaves real questions about how and when they should be used…

Perl's decline was cultural
There's been a flurry of discussion on Hacker News and other tech forums about what killed Perl. I wrote a lot of Perl in the mid 90s and subsequently worked on some of the most trafficked sites on the web in mod_perl in the early 2000s, so I have some thoughts.

Why Speed Matters
The one constant that I have observed in my professional life is that people underestimate the need to move fast. Of course, doing good work takes time. I once spent six months writing a URL parser.
