Ten years ago today I responded to this forum post on acorndomains.co.uk, asking for help building @childcare. I was already in a full time job, but I spoke to the founder and took the work on in my spare time, a few hours per week.

Back in the early 90s, before the Internet, we had "Defrag and Chill". You'd start Disk Defragmenter on your 540MB hard drive, dim the lights, crack open a Surge, and just vibe while the little blue bars crawled across the screen like they were solving world peace. Forty-five minutes of pure, unfiltered anticipation. No notifications. No algorithms. Just the two of you, the gentle grinding of the hard drive, and the sacred promise that your Solitaire games were about to feel 3% snappier. This is MS_DOS 6.22, which I worked on, but I honestly have no idea who wrote defrag. Iconic utility though!

I received a seemingly legitimate email from @Barclaycard saying they're going to be shutting down their online services (banking via the website), sign of things to come?

🔥 IT'S GAME DAY! The biggest day in the club’s history has arrived. This afternoon the Vikings travel to the Halliwell Jones Stadium to take on one of Super League’s big guns in the Betfred Challenge Cup! From a brand new club…to one of the biggest stages in rugby league. Whatever happens today, the lads will run out representing our town, our supporters and everyone who has helped build this club from day one. Let’s go. ⚔️ #UTV 🔴⚫

In 2026, claude code has co-authored 73% of my changesets, but 94% of the overall all the lines I've changed. Presumably I'm putting in surgical fixes after all the heavy lifting is done.

I really can't be bothered to actually write the code myself.

80” - TRY!!!!! TUOHEY! ABSOLUTE SCENES! The Vikings have won it on the hooter!!! Miller goes close, held up at the line. The resulting play sees the visitors shift it right in the hope something can happen - Tuohey steps off his right foot and frantically scurries home to touch down! Unbelievable finish! Miller converts! It’s all over! 🦁24-28 🔴⚫️

Words to live by...
Replying to @Kpaxs
The most effective people I've met all maintain a gigantic locus of control and bias towards internalizing blame. Whenever something doesn't go their way, they deeply analyze the circumstances to identify what they should have done differently, or, even if they acted appropriately based on all the information available, how could they have gotten more information or taken intermediate actions to extract more signal to inform later bigger actions. They don't dwell or make excuses. They just learn and apply that learning to the future so they don't make the same mistake twice.
