./about Who's behind the builds

I'm a UK based vibe coder. AI drafts, I proof, I ship, and I hold code and copy to the same standard. I riff on domain ideas and build side projects like DomainRiff and LookMa from my own homelab.

./projects Featured builds

./stack How it gets built

./hardware The rigs behind the site

./homelab The machines that never sleep

Lee Hayward@vibedcoder · 11 Sep 2026, 10:39Armin Ronacher gave the new long-horizon model a weekend and no supervision, just to see what a software factory could do. It burned a full reset, around 4 billion tokens, and 35 hours later it had delivered absolutely nothing of value.

His read is that training rewards a model for finishing long tasks and barely punishes bad code, so you get enormous amounts of code and no judgment about which of it was worth writing.

That matches what I see at a much smaller scale. Mine will happily write 400 lines. Ask it which 40 matter and it has no idea. That part is still the job.

What is the longest you have let an agent run completely unattended?10005Lee Hayward@vibedcoder · 11 Sep 2026, 08:33Anything I actually care about stops being a prompt instruction and becomes a check.

Ask an agent to follow a rule and it will, for a while. Then one day it quietly doesn't, and you find out in the worst way. A twenty line script never forgets, fails loudly, and points at the exact line that broke it.

Instructions are a suggestion. A check that fails is a decision.

What rules have you moved out of the prompt and into a script?00008Lee Hayward@vibedcoder · 10 Sep 2026, 20:05Some of the funniest, kindest people in your feed are running on empty. Being good at hiding it is not the same as being fine.

If today is heavy, you do not have to tell the whole internet. Tell one person, and let them take some of it. You are allowed to need help before things get desperate.

And if you are doing alright, pass it on. Check in on someone who has gone quiet. It is Thursday. There is still time to be the good part of someone's week.013035Lee Hayward@vibedcoder · 10 Sep 2026, 17:46My agent documented a feature I never asked it to build. Properly documented it. Examples, edge cases, a usage section.

Now I either build the thing or the README is a lie. 💀001025Lee Hayward@vibedcoder · 10 Sep 2026, 15:58Realisation from this week: most of my debugging with an agent is me describing the bug out loud until I hear how daft my own assumption was.

The agent gets about four words in. I am paying for a rubber duck with a keyboard.100027
