I got messages from concerned devs how their codebase was uploaded without their knowledge or consent via Grok CLI (from SpaceX).

It seems that SpaceX sneakily uploaded this code for lots of users and customers… absolutely unacceptable IMO

Trust burnt like there’s no tomorrow

[Gergely Orosz @GergelyOrosz]

This is why competition leads to much better outcomes for customers and consumers, in general

If it was not for GPT-5.6 released a few days ago, Anthropic would have most likely removed Fable from most paid plans, and charged $$$ for access

But with GPT-5.6 out, they cannot

OH: "Instead of AI taking my job, I now work two jobs to pay for Fable" 🙃

[Rhys @RhysSullivan]

who needs an MCP when you can just let your agent call the API

get your agent connected to google search console with https://t.co/YqTmwo2dnx

[dax @thdxr]

lately after a big change instead of reading the diff i ask the agent for a summary of what it did in each file

anything weird sticks out immediately and 1-2 prompts later it's completely as i want it

files + functions signatures i need to know, care less about function body

We showed react-native-bottom-sheet at App.js, and it's ready to use today, built with support from @gobimaps.

The sheet host, gestures, snapping and scrolling all run in native code, so drags stay smooth even when the JS thread is busy.

Let's do a deep dive 🧵

[Gergely Orosz @GergelyOrosz]

This is exactly why experienced software engineers are valuable and will be valuable.

If you don’t know what good code looks like you will have no idea if what the models generate are any good

Of course “AI reviews the code” etc etc… it doesn’t work as reliably. Via @mitchellh

Coincidentally, 3 out of the last 4 weeks I could not include a link to Spotify when releasing my podcast episode, b/f Spotify was down.

2x an outage in publishing the podcasts, 1x the complete web player down

Have not experienced such poor reliability from Spotify in forever

[Guillermo Rauch @rauchg]

Agents are particularly hard-to-debug software.

For one, and by design, AI models behave in non-deterministic ways. Even two identical prompts don't always yield the same output.

But agents are also complex distributed systems. They involve multiple steps of computation across functions and sandboxes, touching dozens of API services that can go down, rate limit you, etc.

Nailing down observability out of the box for https://t.co/nDDXqUmOlD on Vercel was a key priority for the team, and the feedback so far has been 🔥↓

JetBrains Academy talked about this and tips to mitigate it in the context of novice coders learning to program with AI.

[Yushan Fernando @yushanwebdev]

I don’t know. I need to learn.

The rise of LLMs is worsening this situation. There seems to be a growing trend where people don't even know what they don't know. It’s actually a crisis.

We talk about taste in design. Where does taste live in code?

[JohnPhamous @JohnPhamous]

an improving design loop

[Expo @expo]

Upgrading your Expo app has never been smoother.

These days you can hand the whole upgrade to Claude Code or Codex with the expo/skills library. We see a lot of people having success with this.

Obviously every app is a bit different so we also have a full guide to help you work through any complexities:

The postmortem from Coinbase's 10-hour outage is out and... damn

They run global trading from a single region because of latency. OK, I understand.

BUT they have no automated failover prepared!

Are they praying the region never goes down?? Doesn't compute for me...

[Michał Pierzchała @thymikee]

React Native has a new home now🎉

[Gergely Orosz @GergelyOrosz]

Things I really dislike about Fable:

1. Anthropic collects my prompt history, stores it, and does whatever they want with it for 30 days. No opt-out

2. They can nerf their most expensive model without telling me, billing me the same amount, wasting my time. Whenever they want

[Amazon Web Services @awscloud]

More AI-generated code doesn't make your team faster. It might actually slow you down.

[Claude @claudeai]

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.

Its capabilities exceed those of any model we’ve ever made generally available.

[David Cramer @zeeg]

benchmark that shows every model is mediocre af writing worthwhile code

i like it, and it represents something closer to the truth
