       EXTREMELY naive question (I have no experience and likely none of the required technical skills): how hard/expensive would it be to host a #PeerTube instance for scientific talks? Any legal headache, beside getting people authorization?

       Dear AAA game developers: what about allowing us ageing players to increase the UI font size?

       @vicgrinberg I grew up in a house designed to keep the heat out. And while I know a ton of little tricks to keep heat more bearable, there is only so much you can do in British houses, which are designed to keep the heat in.

       @kaia Not an answer to your question (apologies) but... who asks professional copy-editing for a master thesis? 😲

       @kaia Physicists "put things into formulas" all the time. That is not the problem.We just shiver in horror at the thought of having to parse something written in "definition, lemma, lemma, theorem, corollary" form 😉

       @kaia To be on the safe side, send the homework to the prof together with the screenshot, so you can truthfully claim you did everything you could.

       @eniko Probably not very useful to you, but in Mathematica if you divide by zero it returns "ComplexInfinity", which is sort of the right answer 😉

       #PhysicsFactlet Schematic of the epicycle model, as requested by @johncarlosbaez (see https://mathstodon.xyz/@johncarlosbaez/113652794327730499 for his thread on the topic).Apart from having (hopefully) more colorblind-friendly colors, this one is in the #PublicDomain instead of being copyrighted.#Physics #Astronomy

       I would expect all my fellow scientists to be able to spot a dishonest chart from 10 miles away, but it is still good to get a quick refresher from time to time.Also a good resource to give to students, who are often very naive on these things.https://flowingdata.com/projects/dishonest-charts/

       @carnage4life The narrative is always "We noticed none of you were unionized, and thus we can fire you without any repercussion to make the line go up a little bit before the end of the fiscal quarter"

       "AI companies claim their tools couldn't exist without training on copyrighted material. It turns out, they could — it's just really hard. To prove it, AI researchers trained a new model that's less powerful but much more ethical. That's because the LLM's dataset uses only public domain and openly licensed material."tl;dr: If you use public domain data (i.e. you don't steal from authors and creators) you can train a LLM just as good as what was cutting edge a couple of years ago. What makes it difficult is curating the data, but once the data has been curated once, in principle everyone can use it without having to go through the painful part.So the whole "we have to violate copyright and steal intellectual property" is (as everybody already knew) total BS.https://www.engadget.com/ai/it-turns-out-you-can-train-ai-models-without-copyrighted-material-174016619.html?src=rss

       @johncarlosbaez That is because for most people being a novice at driving a car is good enough, which I think was part of @julesh 's point.(In Europe, contrary to the US, the vast majority of cars have a manual gearbox.)

       #PhysicsFactlet Sometimes you need to forgo the intuitive way to define stuff for the sake of actually being able to do anything useful with those definitions.An example of this I always found funny is in knot theory, where a simple loop is considered to be a knot, while anything where the two extremes are dangling are not, including the common overhand knot.This looks weird the first time you see it, but there is a very good reason to go with such a definition: you want to study what you can and can't do by manipulating the knot, and if you have the two extremes dangling, you can always untie any knot, making them all equivalent to a piece of string. In order to be able to say anything interesting about them you need to remove this trivial option, and thus accept the simple loop as a knot.#knots

       @lazy Plenty of good ML research going on at Unis. LLMs and Stable Diffusion are just a microscopic slice of ML and there is a lot of cool stuff you can do with the part that do not require you to steal all intellectual property in the world.@davidrevoy
