Btw, the unicode-out-of-the-box version of LaTeX is called LuaLaTeX and ships with TeX Live.

Thanks. If I understand correctly, Google AI Studio is listed as a Partner, which means they provide (at least) 60000$/year.

Some people have an arrow on top of their head, and when you approach them there is a dialog balloon with "...". If you click on them they give you a task.

Have you compared this to using lua in lualatex?

You are comparing the regulation of business practices to the breach of human rights. Do you also think your water company should be allowed to poison the water coming from your tap?

Why is that? I can imagine doing two folds on a sheet of paper and ending up with three layers of paper. Imo one fold adds one layer.

> Most Europeans had access to Paypal-style money transfers before they had email.

Bank transfers were not instant though, they usually took a work day. This is changing with the introduction of instant transfers, which become mandatory to support this year, and are also not allowed to be more expensive since this year also.

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

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.

New comment by red_trumpet in "There Is No Diffie-Hellman but Elliptic Curve Diffie-Hellman"

red_trumpet — Wed, 28 May 2025 12:36:14 +0000

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 -> 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).

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'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].

> 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.

At this point it might be worthy to note the Whitney Embedding Theorem[1], which states:

> Every smooth n-dimensional manifold can be embedded into R^{2n}.
