Kind of annoying when all the fruit is several meters out of reach

I had quite a few cables with a yellow crimp "jackets" just behind the RJ45. IIRC they came with DSL modems / routers

Pretty trivial to replace CFC with HCFC gases (which breaks down more easily in the atmosphere) compared to moving away from fossil fuels.

You have to put them in pairing mode first: For airpod pros: Open the lid, keep the earbuds in the case, double tap your finger on the case just below the green led, The led should start to flash white and the airpods now appear in the device list in linux so that you can pair with them. Non-pro have an physical button on the rear IIRC.

I have it the opposite way. Moving my right hand from the keyboard to the mouse doesn’t save me time - so as with most things: YMMV

There is definitely also a manager dick-measuring contest based on headcount, going on in large orgs.

Not sure what you mean by cryptographic strength - they are both Unique ID generators, not meant for anything related to cryptography.

UUIDv7 has 62 bits of random data, ULID uses 80 bits, so if anything ULID is "stronger" (meaning less chances of generating the same id within the same millisecond)

I stumbled over your string art turtle some time ago and like one of the commenters on [1], I was wondering about your tool to create points from a image

Not a great analogy, since a digital copy leaves the original intact unlike your apples

Different countries have different laws regarding what falls under freedom of speech. The CDN providers say they take a net-neutrality stance. If a court order from a specific country tells them to block certain sites, I'm pretty sure they will comply, but only for clients coming from within that country.

You are missing the point. Blocking a CDN providers IP range, means blocking all the websites using the CDN - not just the nazi-poster.com.

I've heard that a major hurdle for these "cell-factories", is moving from lab to industrial scale. Ofc initial cost of the product is typically also a lot higher, but that is the same of any product addressing externalities of existing production

Thanks, I see your point. Was not trying to be snarky/funny, but rather come with counter example to parent. I was thinking about the (recent) "Era of globalization" - but perhaps that is too short of a time span to be called an era
