Just biked crossed Paris east to west midday rush hour 12k
Avg speed 17.7 kph
Faster than any car
And probably metro too
And I did not even rush

I'm a very proud human
I did my slides for my next course on bigquery ... all ... by ... myself
no AI, no OpenAI, no Claude
With only knowledge from my tiny organic brain (and a bit of googling)
Feels really good

I'm used to Windows every other release, but W11 is, years after it came out, still a dumpster fire. I can't believe they allowed the team to publish that. It is beta software.
The freaking clock doesn't display the calendar on click, but if you insist, it may tell you it needs... an update.

Great read on what makes production-ready agent systems work:
- Keep it simple with a two-tier architecture—one primary agent orchestrating specialized stateless subagents
- Design subagents as pure functions with no memory

Very soon, asking for code samples to interview developpers
will be as obsolete as handwriting analysis.

Pont d'Austerlitz : retour du danger pour les cyclistes ! ⚠️
Les voies bus / taxi sont ré-ouvertes depuis mi-octobre et les 🚴, 🚌 et 🚖 doivent à nouveau se partager un espace étroit et anxiogène, alors que 4 voies de circulation demeurent sur le pont.

I did amazing work with #ClaudeCode over the summer.
But now with the new usage caps on the Pro account it's useless
I switched to OpenAi #Codex to get things done. works great.
Shame really. I loved Claude code.
