dumdumchan··on Wendelstein 7-X: Gigajoule energy turnover generated for eight minutes
> The energy turnover of 1.3 gigajoule was achieved with an average heating power of 2.7 megawatts, whereby the discharge lasted 480 seconds.

Can a physicist/thermal engineer explain what this means?

Why does postgres do it then?

dumdumchan··on What Will the World Look Like with Less Babies?
> fertility rates tend to fall below the level needed to maintain the population, 2.1 children per woman.

Why 2.1 and not 2?

dumdumchan··on I went to 50 different dentists: almost all gave a different diagnosis (1997)
That's probably how we'll see AI take over. AI will prescribe and humans will do the manual labor.

dumdumchan··on Human Shader
Los alamos used a room full of women for doing simulations when their IBM machine was out of order:

We needed a man to repair the machines, to keep them going and everything. And the army was always going to send this fellow they had, but he was always delayed.

Now, we always were in a hurry. Everything we did, we tried to do as quickly as possible. In this particular case, we worked out all the numerical steps that the machines were supposed to do — multiply this, and then do this, and subtract that. Then we worked out the program, but we didn’t have any machine to test it on. So we set up this room with girls in it. Each one had a Marchant: one was the multiplier, another was the adder. This one cubed — all she did was cube a number on an index card and send it to the next girl.

We went through our cycle this way until we got all the bugs out. It turned out that the speed at which we were able to do it was a hell of a lot faster than the other way, where every single person did all the steps. We got speed with this system that was the predicted speed for the IBM machine. The only difference is that the IBM machines didn’t get tired and could work three shifts. But the girls got tired after a while.

dumdumchan··on GPT-4 is getting worse over time, not better
No surprises here. The entire architecture is based on mass production. There is an immutable base model and the only mutable part is the chat context. There is fine tuning but it takes a long time and there is no temporal relation between the fine tuning prompts. Even then it costs a ton of money. This immutable model is shared among all the users of their services. There has to be a supercomputer version of this product that focuses on quality over quantity.
dumdumchan··on Donald Triplett was autism’s “case 1”
Yes. Level 1 could live their whole life not knowing about it and level 3 autists are basically chimps in human bodies and very difficult to care for if not disciplined properly. https://www.reddit.com/r/regretfulparents/comments/uhu7av/fu...
dumdumchan··on Donald Triplett was autism’s “case 1”
Surprised he lived so long. Maybe because he was a celebrity so he received good care. Level 3s have an average lifespan of 30-40 years.

Windows phones are gone. Why would they want to make MS Office touch friendly? I don't understand why they removed the lines between buttons. This is what made the old UI look organized.
