Most UI applications are broken real-time applications
I’ve been programming for a long time. When I say long time, I mean decades, with an S. Hopefully that’s long enough.

My experience crafting an interpreter with Rust (2021)
Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but…

Unpacking Elixir: Observability
Elixir supports the usual supects of observability. Open Telemetry (OTel), log handlers, capturing metrics. And it does it well. This post will mostly focus on the observability you have on the BEAM that is either incredibly rare to see elsewhere or possibly entirely unique.

Never trust a programmer who says they know C++
I’ve been in an interviewing mindset for awhile and I’ve come to realize something important about C++ in particular. C++ is a “two peak” language. That is to say C++ is the only language I know of where two very different sets of programmers consider themselves well versed in the language. Let me show you in fake…
