At the price per student it probably makes sense to run some voluntary trial exams during the semester. This would give students a chance to get acquainted to the format, help them check their understanding and if the voice is very intimidating allow them to get used to that as well.
As an aside, I'm surprised oral exams aren't possible at 36 students. I feel like I've taken plenty of courses with more participants and oral exams. But the break even point is probably very different from country to country.

The solution of differential equations by separation of variables in physics is also notated in an abusive way. You have some differential equation
dy/dx = g(x)h(y)
You separate the variables by some quick manipulations
dy/h(y) = g(x) dx
And then you have a small step in some coordinate on both sides. So by integrating both sides
\int 1/h(y) dy = \int g(x) dx
you find a solution to your differential equation. Obviously there's a real formal procedure underneath it with also some safeguards. For example you're supposed to check that h(y) doesn't equal 0 at any point. But the happy path in physics is often done without worrying about all that.

Anubis is not meant to stop single endpoints from scraping. It's meant to make it harder for massive AI scrapers. The problematic ones evade rate limiting by using many different ip addresses, and make scraping cheaper on themselves by running headless. Anubis is specifically built to make that kind of scraping harder as i understand it.

Later in the article it seems they expect the EU and the US to sign a trade agreement soon-ish, whereafter they can start importing again. So i think the plan is just to wait it out.

I just did today's word and I thought this was pretty fun. M⁻¹M stumped me for a while, but once I got it, it gave me a good chuckle for how obvious it was in hindsight. I do work in physics, so that gives me a head-start on recognizing all these formula. From the other comments here it seems enjoyment is very correlated to amount of these formula one already knows.
Anyways looking forward to checking this the next couple of days

I don't think I would classify all stages of fetal development as persons, though obviously that line is crossed at some point during pregnancy. However, I read Judith Thomsons "A Defense of Abortion" at some point and she succesfully convinced me fetal personhood doesn't actually matter that much to the morality of abortion.
It can be found on the internet[0], and is only 13 pages. Alternatively I think the wikipedia article outlines her three main arguments quite well[1], and is a quicker read. The most known part is her violinist thought experiment, which can be read to only allow abortion in cases of rape. However, the subsequent parts convinced me that, abortion is moral in general. So long as reasonable steps have been taken to avoid pregnancy.

Ah that's embarrassing. I had wanted to link to this article since it contained some context. https://nypost.com/2022/06/30/twitter-suspends-jordan-peters...
Thanks for pointing it out, will fix.

> I mean: you can disagree with Jordan Peterson (I'm certainly not a religious person, for a start) but what did he do that warranted the old Twitter censoring him?
This tweet[0] was the kickoff point as I recall. I don't really think that getting banned pending deleting the tweet is that egregious. It's one thing to have non-woke opinions and argue for them. I don't follow Jordan Peterson, but I imagine he had posted many times on transgender issues, before he posted the offending tweet.
The issue seems more to have been specifically calling out specific persons, "criminal physician", Elliot Page, in a way that could be construed as inciting to violence

The github repository is a godot project. Godot is a game engine. The quickest way is to download godot. Clone the repository and open the folder as a project in godot.

My impression is that the arrest has to do with telegrams failure to cooperate with law enforcement. Hardware manufactorers don't generally have the ability to monitor and moderate what their product is used for. I guess one could imagine a hardware manufactorer being arrested for refusing to turn over a log of sales or similar.
Obviously god has no such restriction, but he's probably outside French jurisdiction, and i don't think they have an extradition deal in place.

I think that's an overly uncharitable read on this approach. Lots of tasks that have difficult thoughts, that need to be thought before they can be completed, also have phases in which work just has to be done. I'm in the middle of collaborating on an article for submission to a physics journal. I wouldn't term it filler work, but most of the complex thoughts on the problem have been thought through and the work right now is creating a coherent story that goes over our results. An outline method would work fine for this part of the project.
As for the spy novel, i think the outlining is actually quite similar to how Sylvester Stallone described his writing process[0]. You wouldn't fill the outline with generic beats, you would put in your basic plan for the story.

It's related, but as i recall the reason that short pulses cut better has to do with heat transfer. Most heat transfer in metal is due to the vibration in the electrons, being much lighter than the atomic lattice they move in. Very short pulses, means that the heating in the beam path happens faster, than the electrons can transfer it out to the rest of the metal. In long pulses once the metal is vaporised, a lot of the surrounding material has melted. This molten metal cools into jagged structures and that leaves the edge weird. All this doesn't happen if the pulse is short enough. It vaporises metal before the surrounding structure has a chance to heat up.
Here's a figure showing the quite stark difference. https://www.researchgate.net/figure/SEM-image-of-the-substra...

Here's a figure comparing the hole left in a metal surface with normal and femto-second pulses. The difference is quite stark.

Could be that fiber doesn't have any resale value. Whereas copper theft is a somewhat common issue.
I think the most I experienced at the physics department in Aarhus was 70ish students. 200 sounds like a big undertaking.
