<p>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.<p>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.</p>

<p>The solution of differential equations by separation of variables in physics is also notated in an abusive way. You have some differential equation<p>dy/dx = g(x)h(y)<p>You separate the variables by some quick manipulations<p>dy/h(y) = g(x) dx<p>And then you have a small step in some coordinate on both sides. So by integrating both sides<p>\int 1/h(y) dy = \int g(x) dx<p>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.</p>

<p>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.</p>

<p>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.

<p>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.<p>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.<p>[0] <a href="https://rintintin.colorado.edu/~vancecd/phil215/Thomson.pdf" rel="nofollow">https://rintintin.colorado.edu/~vancecd/phil215/Thomson.pdf</a><p>[1] <a href="https://en.wikipedia.org/wiki/A_Defense_of_Abortion" rel="nofollow">https://en.wikipedia.org/wiki/A_Defense_of_Abortion</a></p>

<p>> 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?<p>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.<p>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<p>[0] <a href="https://nypost.com/2022/06/30/twitter-suspends-jordan-peterson-for-elliot-page-sin-tweet/" rel="nofollow">https://nypost.com/2022/06/30/twitter-suspends-jordan-peters...</a></p>

<p>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.<p>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.</p>

<p>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.<p>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.<p>[0] <a href="https://www.youtube.com/watch?v=v_xqfkVNwEU" rel="nofollow">https://www.youtube.com/watch?v=v_xqfkVNwEU</a></p>

<p>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.<p>Here's a figure showing the quite stark difference.

<p>That's fair. I get the wrong answer on the gpt3 and gpt4-o models, but there's always some uncertainty involved in these gaps.

<p>IMO the word intelligence doesn't seem a good description for the thing LLMs possess, they perform pretty well on some tests measuring it. But they're also sometimes wrong in ways intelligent beings (humans) never are. Like this[0] riddle about boats and farmers i stumbled over recently:<p>> A farmer stands on the side of a river with a sheep. There is a boat on the riverbank that has room for exactly one person and one sheep. How can the farmer get across with the sheep in the fewest number of trips?<p>It's obviously riffing on the classic wolf sheep lettuce riddle, but I don't think that's gonna fool any humans into answering anything but the obvious. ChatGPT-4o on the other hand thinks it'll take three trips.<p>They perform a good approximation of intelligence most of the time but the fact that their error pattern is so distinct from humans in some ways, suggests that we probably shouldn't attribute intelligence to them. At least in a human sense of the word.</p>

<p>I think they're talking about linearity as transformations with a linearity score close to 1. They defined that linearity score a little higher up. Such that composing many almost linear transformations will create a total transformation that is very nonlinear.</p>

<p>Obviously it'll be up to some court to decide, but I don't think openai did themselves any favours in a possible voice protection lawsuit, when Sam Altmann tweeted out "her". That makes it seem very much like the imitation was intentional.<p>Additionally I think you're understating the similarity to the Midler v Ford case. It has a similar pattern where they first contacted the "original", then hired an impersonator. The song wasn't at issue, they had a license to that part.<p>I think this part of some of the court documents[0] is especially relevant. Hedwig was the sound alike hired.<p>> Hedwig was told by Young & Rubicam that "they wanted someone who could sound like Bette Midler's recording of [Do You Want To Dance]." She was asked to make a "demo" tape of the song if she was interested. She made an a capella demo and got the job.<p>> At the direction of Young & Rubicam, Hedwig then made a record for the commercial. The Midler record of "Do You Want To Dance" was first played to her. She was told to "sound as much as possible like the Bette Midler record," leaving out only a few "aahs" unsuitable for the commercial. Hedwig imitated Midler to the best of her ability.<p>> After the commercial was aired Midler was told by "a number of people" that it "sounded exactly" like her record of "Do You Want To Dance." Hedwig was told by "many personal friends" that they thought it was Midler singing the commercial. Ken Fritz, a personal manager in the entertainment business not associated with Midler, declares by affidavit that he heard the commercial on more than one occasion and thought Midler was doing the singing.<p>> Neither the name nor the picture of Midler was used in the commercial; Young & Rubicam had a license from the copyright holder to use the song. At issue in this case is only the protection of Midler's voice.<p>So the fact that us random internet commentors did not recognize her voice doesn't seem to matter in cases like these. It's enough that the sound alike had been told to mimic the original voice, and that people familiar with the voice be fooled.<p>[0] <a href="https://law.justia.com/cases/federal/appellate-courts/F2/849/460/37485/" rel="nofollow">https://law.justia.com/cases/federal/appellate-courts/F2/849...</a></p>

<p>Theres no smoothing involved, it's three distinct domains with different function definitions. Top part is log(x) from [a,\infty), bottom part is -log(-x) from (-\infty,-a] and the middle part is cx from (-a,a). With c chosen to ensure continuity in the transform.<p>In the example from matplotlib I linked in the earlier comment they call out that the symlog transform has a discontinous gradient at the a's, and that the asinh transform can be used instead if that's a problem.<p>Edit: On reflection it's probably not entirely correct to talk about it as choosing an appropriate c. Since that transform seems to kinda break apart around a=1. Simpler to consider it a matter of plotting on a logarithmic scale down to some value. Then continuing the plot on a linear scale until you reach the negative value on the other side and then plotting on a negative logarithmic scale (-log(|x|)).</p>
