🐧 Linus Torvalds gets angry when people say 99% of our code is written by AI, he told the audience at the Open Source Summit.

Did OpenAI nerf GPT 5.5?

[Theo Kallioras @tkallioras]

Trying Claude Opus again after months of mostly using GPT-5.5, and I was pleasantly surprised. Opus feels better at picking up intent and understanding what I’m actually asking for.

[Theo Kallioras @tkallioras]

Tried it today. It completed the (very well defined) task of migrating XCTests to Swift Testing and then it started a broader and unnecessary dependency refactor of the whole project, where I had to intervene and stop it. Feels very beta still.

how to use /goal in codex — keep Codex working on a persistent objective until it's solved:

@emil_priver Squash requests

[Gergely Orosz @GergelyOrosz]

Pull requests disappeared on GitHub for many (all?) users.

This is just the latest outage on a platform where reliability has been beyond unacceptable the last few months.

A fair question: at what point would customers move? How much pain is too much? And where do they move?

[Theo Kallioras @tkallioras]

@GergelyOrosz I am thinking of doing the exact same thing and move over to Revolut

[Theo Kallioras @tkallioras]

@thsottiaux That's also happening on the web. Some times it stays unresponsive until it ultimately fails.

@steipete @bdkjones SQLite FTW

@GergelyOrosz My favorite one is “you want [x process] to be boring”.
The past few weeks I’ve been hitting the block button like crazy.

@T_Zahil Love the design

[Theo Kallioras @tkallioras]

@camsoft2000 Yeap same results here, half the time goes haywire.

[Theo Kallioras @tkallioras]

Codex feels nerfed since yesterday. Goes off-script, fails to scan the code base effectively. Something has changed.

[Theo Kallioras @tkallioras]

@juanjovn @xmarioapps Good to know thnx

[Theo Kallioras @tkallioras]

@juanjovn @xmarioapps It already happened to me once, but I thought it was random. What are they trying to achieve with this?

[Theo Kallioras @tkallioras]

@SebJVidal @No_Wham Thanks, yes I’ve seen that before. I’m waiting for adoption to increase to see how stable it is.

[Theo Kallioras @tkallioras]

@T_Zahil @cursor_ai Try Codex

[Theo Kallioras @tkallioras]

I see you, and I raise you with this App Store review
