Observations on what's around me and projects I'm working on.


Creating a large GitHub Gist

The UI at GitHub limits the size of the gist you can create. The way around this is via the gh command line. For example: $ gh gist create path/to/big.txt- Creating gist big.txt✓ Created secret gist big.txt

“There are few sights more quietly radical than a snowdrop”

There is also joy in its restraint. The snowdrop does not compete. It does not dominate a landscape. It invites you to look closely. You must stoop to see it properly, which feels appropriate. Hope, at this time of year, should make us bow our heads a little. Perfect from: The Snowdrop – flower of hope, Sussex Bylines,...

Review code changes, then discard

Sometimes I want to review a PR by looking at the changes in my editor locally. Once I'm happy, I throw away the changes.  The command sequence to do this is: git checkout maingit merge --squash branch-name-here# <do productive and important review work here>git reset --hard HEADAnd if I forget the --squash, it's git...

Anyone for a game of Tetris?

Brighton Philharmonic Orchestra does Nyman

I'm still stunned that regular human beings, who somehow aren't super famous, can get on a stage and make such perfect sounds together. Without amplifiers screwing up the sound.  This was at a BPO concert at the Dome. A two parter, with a trumpet concerto in part one. I don't count myself as a fan of the trumpet, but...

Impressions after ten days with a Polestar 2

We hired a car over Christmas because Fiat are taking months to get parts to fix ours (after an accident—nobody was hurt). We specified "electric" but didn't have a choice and ended up with a Polestar 2. I knew nothing about Polestar. It's way too big for us, so daunting, but it was great to try something different for...

Childhood flu exposure lasts a lifetime

Reading: Immunological sin: how a person’s earliest flu infections dictate life-long immunity, Nature, 17 December 2025.

Cost savings We've aimed to optimise running costs. It's tricky to compare this year to last year: our electricity unit cost went up...

Fun listening

I'm getting lots of joy from some superb nonsense: Time of the Week Strong Message Here (not nonsense) It's a Fair Cop The Unbelievable Truth and of course The Bugle. Wow: I need to diversify where I get my laughs from. This is all pretty much BBC Radio 4.

Progress on AI drug discovery

There's an upbeat article in The Economist: An AI revolution in drugmaking is under way (5 January 2026).  It rehashes figures from a 2024 study: AI-designed drugs are whizzing through the preclinical phase (that before human trials begin) in only 12-18 months, compared with three to five years previously. And the...

AI in 2026

Of all the hot takes on what will happen to AI in 2026, I'm drawn to this one from Philip Ball: It’s unlikely that 2026 will be a make-or-break time for AI – many aspects of it are here to stay – but there could be turbulence for the industry, particularly if the investment bubble bursts, as many anticipate....
