That is of course true, but it is at least not a totally unreasonable practice, unlike using fresh water straight off the grid as a cooling source.

For cooling you can also use a heat exchanger and dump it into a river or an ocean or so.

Abundant access to a source of cooling can help offset high grid prices. Well places centres can a ton of money that way.

No, they are aiming for plutocracy. They don't want solutions that is good for society, they want solutions that make them richer.

You are missing the business model - buy has-been platforms and frameworks and charge big bucks for maintenance. Customers eventually manage to migrate off you, but it is fine cause you buy some other has-been stack and then overcharge for that.

Also it is very easy to find situations where hash table lookups dominate a measurement, but where the answer isn't to make the lookup faster but to make fewer lookups.

New comment by yxhuvud in "Finding all regex matches has always been O(n²)"

yxhuvud — Tue, 24 Mar 2026 08:30:31 +0000

Hmm. I kinda wonder how something like a regexp engine based on marpa would fall. It would probably be slower in the common well behaved cases, as well as preprocessing. But I wonder if there are any cases that couldn't be done in a O(n) way if you limit yourself to only one match (instead of finding all possible matches like it actually can do). Marpa definitely handles most degenerate regexp cases linearly (once you make the match generation not do overlapping entries), but there may be some regexp feature it can't handle?

Bringing a fully general CFG parser to parse regexps would be like hunting mosquitos with a nuke though..

Which is a thing that depend very much on team culture. In my team it is perhaps 15 min for smaller fixes to get signoff. There is a virtuous feedback loop here - smaller PRs give faster reviews, but also more frequent PRs, which give more frequent times to actually check if there is something new to review.

If you changed from glibc to jemalloc and that solved your issues, then you should blame glibc, not the JVM.

The drones that are mainly used there are the flying kind.

I'm actually somewhat surprised Iran is openly telling us they are using underwater drones for this. That piece of technological advance has gone mostly under the radar (!) so far.

I'm doing crystal bindings for pipewire and wayland clients. It is nice to be able to do so much with so little. github / yxhuvud / [pipewire_cr | wayland_client]

I'm not certain I buy it, but I find it a little hard to motivate the training being fair use if used to regenerate the project in a different licence.

It is fairly ok for meetings and calendar integration.

It is dogshit at chatting, however.

We would have, if the expensive memory was a long term trend. It is not - eventually the supply will expand to match demand. There is no fundamental lack of raw materials underlying the issues, it is just a demand shock.

What you are asking for is to make a library definition replacement to .h-files that contain sufficient information to make rust safe. That is a big, big step and would be fantastic not only for rust but for any other language trying to break out of the C tar pit.

What Apple restricts and is legal are not the same. Apple is doing malicious compliance and the legal system ain't buying it. But it takes some time and iterations to shake out.

In many cases government texts are not covered by copyright, so it may not even be relevant here, regardless of it is is allowed to copy the data or not.

There are middle grounds - for example you could redact any PII before publishing it.

What we do here in sweden is that you can ask the courts for any court document (unless it is confidential for some reason).

But the courts are allowed to do it conditionally, so a common condition if you ask for a lot of cases is to condition it to redact any PII before making the data searchable. Having the effect that people that actually care and know what to look for, can find information. But you can't randomly just search for someone and see what you get.

There is also a second registry separate from the courts that used to keep track of people that have been convicted during the last n years that is used for backgrounds checks etc.
