Nawrocki vetoes Poland’s €44 bln EU defense loan plan President Karol Nawrocki has announced he will veto legislation paving the way for Poland to tap nearly €44 billion in EU defense loans.

Blatant betrayal of Europe’s safety.

ECMAScript Euphoria! 🎉

We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4.

Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌

Chrome extension idea: goes through your feed and automatically blocks people writing large scale "trust me bro" economic/industry predictions.

Boldly and loudly predicting the future should be a disqualifying indicator of poor judgement in general. You'd only set yourself up for failure like that if you're a dunce or a propagandist.

Sorry to hear that, not sure if an on-site position in Berlin would be interesting to you: jobs.ashbyhq.com/Kombo (more than happy to talk more if so). Nonetheless, good luck with your search!

Confidential computing
This is the domain of confidential computing. Confidential computing uses hardware-enforced isolation to run code in a Trusted Execution Environment (TEE). The host machine provides CPU, memory, and power, but cannot access the TEE’s memory or execution state.

LLMs are fundamentally stateless—input in, output out—which makes them ideal for this environment. For Confer, we run inference inside a confidential VM. Your prompts are encrypted from your device directly into the TEE using Noise Pipes, processed there, and responses are encrypted back. The host never sees plaintext.

But this raises an obvious concern: even if we have encrypted pipes in and out of an encrypted environment, it really matters what is running inside that environment. The client needs assurance that the code running is actually doing what it claims.

As hyped as Claude Code + Obsidian is, I have no desire to upload my personal unencrypted vault data to Anthropic or anyone else.

I hope that the ideas of private inference and confidential computing that Moxie described take off. It's how all LLMs should work.

I like this setting for VS Code from Ben Frain. JUST show the vertical line for the current indentation, not all of them

```
"workbench.colorCustomizations": {
"editorIndentGuide.background1": "#00000001",
"editorIndentGuide.activeBackground1": "#ff9900"
}
```

Anyone knows if stuff like this is Claude Code's fault or Cursor/VS Code's?

ViroReact wasn’t working, so I slopped a simple native module for ARKit to enable distance measurements similar to what the built-in Measure app offers. Quite happy with how it turned out – maybe I will clean it up and open source it!

PSA: if you have a business pitch for someone, or want them to hire you as a contractor, your chances of success decrease by 100% if you have ChatGPT write the message for you. 😅

Why are @github.com tokens allowed to have no expiry but @npmjs.bsky.social are about to make every IT team's lives a living hell? This is just more security theatre. Think harder @microsoft.com.

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?

It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

This is probably a long shot, but if any of my virtual friends here has/knows an apartment in Berlin that will be free from November (or around that time), I would love to know more! RTs welcome!

If you’re going to attach AI slop as unnecessary visual supplement to your post and can’t be bothered to even write the alt-text, just copy and paste the prompt you used to generate it.
