Just to expand slightly on this: Some old procedures, probably from the main frame age, live to this day in old institution, including the belief that you can ask people about their personal number over the telephone and auth them that way.

I don't think any IT infrastructure is doing it, it's all by a national single-sign on system.

A little nitpick on the sound quality of piano VSTs: I don't know about drum VSTs but I don't think your piano VST is actually a good example, because piano synthesis is actually pretty darn hard.

I haven't followed this closely the past few years, but it used to be pretty obvious you were listening to a VST compared to a real instrument in actual playing. When you compare recordings, sample based ones sound awesome as long as you just try a single note, but they were obviously missing something in the sympathetic resonances (sounding worse than my upright piano which is perhaps a 20th percentile piano), and the more physics based ones had not so great tones.

I've actually been hoping that someone would try to apply deep learning to piano VSTs, even emailed a few researchers, but no reply. If something new has come up I'm not aware of, I apologize.

FWIW, the latest analysis I've seen seems to suggest that biomethane is probably the way to go for last-resort long term backup. Hydrogen is just too fickle.

It is not an uncommon problem with geothermal.

Alcoholism was a huge problem if you go back several 100 of years where home distillation was rampant, and there is indeed regulation and taxes to control it in Denmark. You can ask an LLM for more details. It's just not done the way say Sweden does it.

You start with the queen. Everyone knows who she is.

Probably only few. Nuclear attracts dreamers. But would they pay the price, literally? Cost is the real reason nuclear is dying.

Can I recommend playing Bach?

The specialization goes both ways, though, I'm much better playing Alberti bass with my left hand compared to the right.

Diamonds? You can use them in a drill bit.

No, you need to match the demand curve at all times.

Source please? The numbers I have seen of real opex paint a different picture. In general, nuclear plants close because of cost.

You just write "spent two years raising my youngest kid [building tree houses and whatnot]". If you keep a bit up with tech, why would anyone think twice about that? They wouldn't where I live.

Yes.

Some years ago we ported some code from querying out the data and tallying in Python (how many are in each bucket) to using SQL to do that. It didn't speed up the execution. I was surprised by that, but I guess the Postgres interpreter is roughly the same speed as Python, which when you think about it perhaps isn't that surprising.

But Python is truly general purpose while the core query stuff in SQL is really specialized (we were not using stored procedures). So if Pypy can get 5x speedup, it seems to me that it should be possible to get the same kind of speed up in Postgres. I guess it needs funding and someone as smart as the Pypy people.

The suggestion was not to use an LLM to compile the expression, but to use an LLM to build the compiler.

Not sure, but I solved a similar problem many years ago, and ended up concluding it was silly to send all the data to the client when the client didn't have the visual resolution to show it anyway. So I sampled it adaptively client-side by precomputing and storing multiple zoom-levels. That way the client-side chart app would get the points and you could zoom in, but you'd only ever retrieve about 1000-2000 points at the time.
