The landing page says "Who are we to tell you how to use your computer?" so I'm assuming you'll be able to do whatever you want with it. Similar to the Steam Deck.

I can't wait to see what she accomplishes at Intel. She has a very bright future ahead of her!

I think they have different use cases. MCP is for tool calling, A2A for agents communicating between themselves.

The third season of Twin Peaks is the best piece of television I ever watched. Rest in peace, you will be missed.

The Primeagen had a stream to test it out where he found a pretty big security problem (that was fixed eventually)

I am almost sure they use AI to generate subtitles too. Some subtitles have sentences that really look like automatic transcription errors.

Yep, we encountered the same problem right in the middle of some critical infrastructural maintenance we were doing. Really frustrating.

That book gave me the highest dose of existential crisis I've ever felt. I should probably re-read it.

Yeah! Before I started contributing I always thought that I wasn't good enough to even try. When I started I noticed how welcoming the communities usually are and that motivated me to contribute me even more. Nowadays I try to motivate people whenever I can.
