How to build a coding agent
It's not that hard to build a coding agent. 300 lines of code running in a loop with LLM tokens. You just keep throwing tokens at the loop, and then you've got yourself an agent.

I'm a software engineer who writes about AI-assisted software development. I created the Ralph loop, which runs a coding agent in a loop until the work is done. It's the technique loop engineering grew out of.

Unikernels were hard. key word: were
Justin Cormack, who worked on MirageOS back in the day, called me at the pub to talk about why unikernels are coming back. The friction that made them hard is gone, the operating system is design debt, and if you care about security you should seriously consider them.

I discovered this back around Christmas where I asked an LLM to make me an Haskell audio library by transpiling a rust implementation. An “oh fuck” moment in timeOver the Christmas break I’ve been critically looking

Reflections on software development from anywhere on an iPad
The Macbook Pro M1 is the software development laptop of choice yet I love my iPad considerably more. I'm all in with my thin client for hipsters. Here’s what I’ve learned over the months and how my baremetal homelab in the sky is setup.
