Thanks for sharing. A couple of friends live in Northern Italy and I tend to keep an eye on such weather for them. Time to tell them to buckle up.

This is going to drive massive rain/flood events around the Mediterranean once summer has peaked, right?

Junie wrote some tests for me and in her enthusiasm, she added a very flaky test:

// Assert - we should find different selections at least once
// Note: This is a probabilistic test, but with 10 attempts and selecting 2 from 5
// the probability of getting the same selection every time is very low

TIL: My habit of keeping tabs open is really really really REALLY bad for my energy usage. I noticed the past couple of days that my MBP runs hot even when I'm hardly doing anything. Turns out Firefox was using 75% CPU+GPU on idle tabs... I shut them all down... Retraining this is going to be hard

<rant>Has anyone else noticed that apps like Word and Excel now have "updates" almost daily? I feel like I'm greeted by the "We've made some improvements, please restart"-banner every time I activate one of those apps... </rant> (Thanks for "listening" ๐Ÿ˜…)

I wrote my first line of #java in 2000. It was for the university course โ€œObject Oriented Programmingโ€. During the lessons we wrote code with pen and paper and once a week we had practical exercises where we coded in Notepad ๐Ÿ˜…

Sorry, ranting time, but I'll keep it short: WHY the F does Excel popup a window saying "Contacting the server" when I try to copy a series of cells to the clipboard!? WHY!?!

Sometimes I hate that we invented the internet ๐Ÿ˜…

I have to make a small correction: the title of the talk is โ€œRegenerative Intelligenceโ€, the artificial is only a part of it. Very interesting future sight of where we should aim for in our endeavors.

When I posted this, I didn't yet know you were referring to Trump's tantrum towards Zelensky. I wholeheartedly agree and will try to de-US my life as well. I have never seen more childish behavior outside of highschool, let alone international politics.
