gpt 5.6, gpt portunhol! sol, terra, luna!

Viana do Castelo's weather is like San Francisco's. Whole Europe is melting, and here I have to wear a sweater.

[Marcus Derencius @derencius]

suddenly Claude Code switched to full screen tui.
- scroll got messed up
- text selection got messed up
- links in the text stopped working.

to undo, use
/tui default

the claude code I setup to review my PRs find issues that my local claude code didn't. When I asked why, it blamed me.

[Marcus Derencius @derencius]

@sergey_kaplich no, it is easy. and with a kite you refine your surfing skills 100% of the time, instead of just a few minutes per hour when paddling.

[Marcus Derencius @derencius]

Kitesurfing feels like surfing with AI. The kite removes the effort (paddling, wave timing) then each minute in the water is just enjoying the freedom to do whatever you want. it is easy to get boring.

when I surf, the struggle is part interesting.

[Marcus Derencius @derencius]

and there is some debate between surfers and kitesurfers that feel similar to the debate of using AI or not. feels like philosophical times.

i might cancel my grammarly sub so my writing errors stay resulting in a more human made text.

[Marcus Derencius @derencius]

fable can be the greatest, but gpt doing adversarial review still find issues.

[Marcus Derencius @derencius]

I was at 90% of weekly limit. 0% now. lets fable!

[Amol Avasare @TheAmolAvasare]

To celebrate the Fable 5 launch, we just reset 5-hour and weekly limits for all users across our products!

Enjoy 🚀

for the past year I've been building AI agents at @GrowthXAI to help companies like Lovable, Brex, Ramp, and SentinelOne grow their AI presence.

billions of tokens later, we compiled everything we learned into one system. it goes live today.

we present GrowthOS!

so claude chrome doesn't work in Claude Code when using via api.

[Marcus Derencius @derencius]

how to have success with /goals? set challenging ones:

[Marcus Derencius @derencius]

using opus via vertex (api) seems much faster than opus via anthropic team plan.

[Marcus Derencius @derencius]

Claude Code debugged its logs to identify that opus 4.8 1m is kinda slow.

[Marcus Derencius @derencius]

using claude chrome to identify memory leaks on a heavy page. impressive.

[Marcus Derencius @derencius]

@paulg adding this to my claude md

@davidasinclair today I told my openclaw while it was analyzing my Oura data that some light sleep that oura tracked is misleading, because I was light sleeping. I felt better knowing that my sleep score should be higher.
