I really like Tailwind CSS.

OCaml is a pragmatic functional language.

As discussed in a previous post, I have been working for a while on running Tailwind CSS without a Node.js dependency.

On 23 April, our pure-OCaml CCSDS protocol stack booted up in low Earth orbit!

On 15 April, the Cambridge Ring, the alumni society of the University of Cambridge Computer Laboratory, named our paper "Functional Networking for Millions of Docker Desktops" its Publication of the Year.

Tailwind CSS introduced a clever way to manage the HTML/CSS split: encode CSS properties as class names.

A satellite link is a radio signal between a ground station and a spacecraft moving at 7.5 km/s, visible for 10 minutes at a time, over a channel measured in kilobits per second.

In January 2026, two things happened that changed how satellite operators think about collision risk.

I have rewritten my website in OCaml more times than I can count (from ocaml-cow to Canopy to custom MirageOS unikernels).

Satellites are becoming software platforms.

Four years ago, Thales Alenia Space invited me into their integration hall in Cannes.

Back in 2012, Anil Madhavapeddy and I were building MirageOS as a library OS, and we started to accumulate a lot of libraries to manage manually.

The same conversation keeps happening.

Our 2013 ASPLOS paper, "Unikernels: Library Operating Systems for the Cloud", received a test-of-time award in March 2025.

Last week I attended the F Prime workshop at JPL, over 100 people, from CubeSat student teams to flagship mission engineers.

Hello world, finally this is live :-) The last couple of weeks have been pretty intense as I've been moving to LA with my family.
