@mickep For x=15 you have (x+10) * (100 - (x-10)/2 ) + (9900) * ln( (90) / (100 + x)) = 2437.5 + (-2426.71). IMHO not unexpected to lose precision with arithmetics as the ones in Knuth's TeX.
@daleif The noise is in general expected for an error calculation/plotting: You're making a difference of very large very similar numbers, that's always gonna be noisy. I'm not sure why the noise jumps to being an order of magnitude larger, but that's really beyond the point IMHO.
@Skillmon To close the loop on this: It's a recurring bug -- we fix it, and then another change makes it reappear. The underlying issue is some sort of a race condition and the devs hope that they fixed it for good this time (regardless of how long "for good" lasts :-) ) Thanks again for letting us know!
@samcarter Or it's jsut the right phase in the live of the company, where they again manage to understand that if you want to build a community-based site, you might need the ... you know ... communities? :) It's a cycle: You have a good stuff, you try to squeeze it, you make it worse, so you release your squeeze, rethink your strategy, make it better, and repeat.
@DavidCarlisle yep, but (a) the characters in the font tend to be different size, thus catching Ace unprepared, and (b) there's some multi-character input methods and whatnots which confuse Ace.
@barbarabeeton The only bad thing about food in Prague is that it's great if you love meat, really good if you are only fish, good if you are vegeterian, and horrible if you're vegan. (Which couple people in our company are, and it is an issue.)
@samcarter Yeah exactly -- this sounds like that SE wants to bring in people that don't know how to ask a question, which has been the main differentiator between SE and just about anything else (Reddit to name one).
@John I work for Overleaf support :) ninety is nothing :D But ultimately, what David said. Also, we tested making errors more prominent, and were strongly told by users to revert it /shrug. Since then we at least introduced the gutter markings for errors and warnings, and that helped somewhat.
@DavidCarlisle the way we build our texlive docker image is (simplified version): (1) install all of texlive via tl_install; (2) do some fonts shananigans; (3) remove the doc tree. So in this sense, we do guarantee that non-latex tools like tex (plain), context, platex or pbibtex work.
@DavidCarlisle I don't know the details. Our devs just decided that lezer is the most native to CM6, probably with best feature compatibility, so we go for it :)
@cfr It is more secure against leaked or compromised passwords, but not really against compromised devices, in particular if your password app is kept unlocked. I have 1password set up to autolock, and I wouldn't ever store my 2fa codes on the computer -- they are on my phone, and backed up on my tablet, with the reset codes being in my bank safebox.
@daleif that's quite a dead end unfortunately :( The only way out is to identify the largest files, download these one by one, delete them from the project until it's under 1GB and then try again.
