Low Code Software Development Is a Lie
I’ve been writing custom software for a long time and one of the things that annoys me most is when a client adopts the position that there is a silver bullet which will reduce or remove the inherent complexity of this task. This happens more often than you’d think and guess what? They are almost always wrong. Perhaps…

Scaffolded LLMs as natural language computers
Recently, LLM-based agents have been all the rage – with projects like AutoGPT showing how easy it is to wrap an LLM in a simple agentic loop and prompt it to achieve real-world tasks. More generally, we can think about the class of ‘scaffolded’ 1 LLM systems – which wrap...

Displaying My Washing Machine's Remaining Time with Curl, Jq, and Pizauth
A couple of months ago our washing machine produced a considerable quantity of smoke when I opened its door, which I interpreted as a suggestion that a replacement was needed. After rummaging around the internet for advice, a couple of days later a new Miele washing machine took its place in our home.

Who invented vector clocks?
Back in spring 2020, I was wrapping up the distributed systems course I was teaching, and for the last lecture, decided to spend a little time poking at the question of who actually invented vector clocks. Most people who need something to cite for vector clocks cite Friedemann Mattern’s “Virtual Time and Global…

Modular Errors in Rust
It is thankfully common wisdom nowadays that documentation must be placed as near as possible to the code it documents, and should be fine-grained to a minimal unit of describability (the thing being documented). The practice provides numerous benefits to the codebase and project as a whole:

A 1.5GB string
In my previous role, I supported a Java service that operated similarly to RDP or Citrix by enabling remote UI functionality. This service relied on sessions, which consisted of interconnected Java objects that were supposed to be cleaned up either when a user logged out or after a predetermined timeout period.
