Apprenticeship is alive and well across Europe, most famously probably in Germany. The majority of young adults there completes one.

Are you sure about this? Your quoted article only has data from >20 years ago. I wouldn't be surprised if nowadays more people study at university than do an apprenticeship

Is there any way to get this to run in a browser? I get until the point where the GUI starts up (without a modem though), but then I cannot move the cursor.

This is trivially shown to be false.

Imagine a system with a background/quiescent energy consumption of 1000kCal/day.

Imagine that same system can buffer up to 500kCal for up to 24 hours store excess energy in circulation.

Imagine it converts excess energy to stored energy at an efficiency of 50%.

Assume activity correlates with marginal energy consumption but also increases in the presence of excess energy.

A system such as the one described would have very different behaviors during alternate day fasting (0kCal for 24hrs, 5000kCal for 24hrs) than consuming 2500kCal daily.

The human body is more complex than the system I just described, but it is a useful model to consider for this context.

So, the excess energy in your model is just excreted? Does that also happen in the human body?

The only thing the cookie law has accomplished for users, is pestering everyone with endless popups (full of dark patterns). WWW is pretty much unbearable to use without uBlock filtering that nonsense away. User tracking and fingerprinting has moved server side. Zero user privacy has been gained, because there's too much money to be made and the industry routed around this brain dead legislation.

English football, unlike tic-tac-toe, can be thrilling and end in a draw. Possession mix, shots on goal, and more stats are useful to determine how exciting a match was from a box score.

Frankly, for me the most boring is a 2-0 win where the team scores those 2 in the first 20 to 30 minutes, swaps to a 5-4-1, and plays tiki-taka passing possession control without trying hard to advance the ball for the remaining hour of the match.

Tic-tac-toe certainly can end in a draw though...

Aw hell they picked up on that stupid American capitalist crap?

I worked in Germany in 2005 and back then everything was fixed price per kilometer for each train class, and you could get rail passes of sorts and get on whatever the hell trains you want during their validity. I'd take train roundtrips after work just to watch sunsets.

red_trumpet · 2 months ago
The price concept discussed above applies to long-distance trains. Local trains are still different, especially if you have the "Deutschlandticket" (germany ticket) you can just hop on any local train you like.

I don't get this article. They make a big fuss about looking for the right category, because apparently the category of groups cannot explain the difficulty of breaking Diffie-Hellman, since there is an isomorphism <g> -> Z/nZ. But the same isomorphism exists in the category of algebraic varieties! So was all in vain?

To me this sounds a bit like an a-posteriori justification of why people use elliptic curves to do cryptography. This feels weird to me, as elliptic curves are a well-studied subject in algebraic geometry, whose history reaches back over 150 years to Clebsch. So when Victor Miller and Neal Koblitz proposed to do cryptography with them, they already knew very well about elliptic curves (both have a background in algebraic geometry of finite fields).

I know KaTeX supposedly lets you copy-and-paste the text, but that won't get you text that is fit for any purpose.

Better typography helps with reading. The same reason someone would complain if this was typed in Comic Sans. Also the images don't scale well, so if you look at this with a high resolution display, either the images are too small or not sharp.

I'm trying to read the paper https://arxiv.org/pdf/2405.10732 to get a sense of things in more detail (probably quite helplessly).

It's talking about ellipticity. Should I be imagining a kind of tightly packed set of ellipses at all scales and shapes (kind of undulating or expanding and collapsing I guess)?

Does anyone have a better gloss-level sense of "the new method"?

red_trumpet · 3 months ago
I'd guess the term "elliptic" has more to do with elliptic operators[1] than with ellipses. Of course, ultimately elliptic operators are named after ellipses, but the association is not as direct as you might imagine[2].

Not a good term. Anti-personnel mines do exactly what they are intended to do. These devices/software do something against the interests of the user in the process of doing something the user actually wants (otherwise why would the user even get them?).

Perhaps "Faustian computing"?

> Anti-personnel mines do exactly what they are intended to do. These devices/software do something against the interests of the user in the process of doing something the user actually wants

Actually, I think you got it backwards: Anti-personnel mines are highly problematic especially when they are not needed anymore. They often linger in the ground for extended times after a conflict and are a cause of death and injuries in civilians, who just want to live their lives. Contrary to this, anti-personnel computing is problematic in the times when civilians are incentivized to use it.
