it's like an adorable little new grad who's just discovered that the viterbi algorithm exists and now uses it on everything – it's shoehorned it into three different things wildly inappropriately over the past 24 hours

After a cracking 6 months helping out plain.com with their DX and platform, I'll be looking for new work from the end of July. If you're after a full-stack engineer with experience working on web, mobile, backend, infra and AI projects, give me a shout!

I had a (minimal) hand in this; it feels like such an upgrade, and a pleasure working with @ashugeo on the engineering – maybe designers should code after all
After a few months of work… @tuple has a new website! 🥳 Check it out 👉 tuple.app

Manchester Airport remains the worst airport in the world. 2 hours to drop bags and go through security; what a shitshow

Boring tweet: love me a database index. From 5 seconds for one query to 50ms with no extra lines of code, we love to see it

I spent far too much time on this. Jungle is massive.
Please, please will someone sample @amolrajan saying: "I can't accept Drum & Bass. We need Jungle, I'm afraid." 👊

After a week or so of coding in nothing but C++ I really have no idea how full-time C++ developers do it
