I do see why it would depress the amount of caring that happens, but I don't see the positive feedback loop mechanism (why would caring for others as much as for yourself decrease how much you value yourself?).

@madargon I'd wager that it's a suspension, though I'm very surprised by the presence of smell.

I am not very familiar with Meson, but I found it weird that the build would start without opencascade (well, with meson unable to find it) and only fail somewhere in the middle due to missing headers. Would it make sense to cause it to fail immediately, like for other dependencies?

Today I learned that when you edit a Mastodon post:
- the web UI allows you to look at previous versions,
- ActivityPub API doesn't seem to mention their existence.

This makes me sad, because it means that (a) there's no uniform version identifier preserved across instances that have the same post (which could help detect malfeasance) (b) custom Fedi clients are denied access to something that is exposed via the Web UI, which forces people to use the web ui (or another instance's web ui, if that instance received all the versions) instead of an APub client.

(Aside, I've also found a server that 403s on attempts to use curl's User-Agent to fetch posts from it. I'm not sure how I feel about that.)

Ah! HLI, dass die vorherige Versionen sind im Web-UI aufrufbar.

@badlogic @mayr_matthias

Werden die veraltete Versionen nicht einfach gelöscht auf dem Mastodon-Server?

I have no clue what the problem you're describing could be there, but this reminded me of very old DMUs that did have such a problem: they needed air pressure to engage or disengage final drives (in forward or reverse), and they couldn't be towed with them engaged (because that would damage the gearbox that was receiving no oil flow). See https://www.youtube.com/watch?v=XCQKvEy6jVs for a description of that ancient train's failure modes.

Everyone will have their https://xkcd.com/1053/ moment regarding furries. (I don't remember when mine was, but I must have been reading http://freefall.purssia.com for years before even becoming aware of the concept.)

There's the whole area of dealing with signals with high carrier frequency (compared with bandwidth), where it's not very practical to digitize the signal at least until you've frequency-shifted it. If you do any beamforming, you need to do it in analog realm too. Sometimes doing more in the analog realm lets one get away with e.g. 1-bit ADC.

There's the area of regulating power. While for most small applications you can find ready-made switching regulators, and rules of thumb regarding decoupling, understanding of the internals lets one realize e.g. what does it take to get the whole system to oscillate in a divergent fashion. Same understanding (and ability to do something atypical) also helps with energy efficiency.

(Note that there are scaling laws here: things that were once problematic on low frequencies on very long cables are very similar to problems that you get from high frequencies on very short cables. We don't necessarily deal with them in the same way, but the area of things that work badly is more similar than I'd expect before I realized that.)

NixOS supports installing Firefox extensions as part of the OS (as in, so that the extensions come from the same build system/package manager as the rest of the OS). It makes use of the fact that you can disable extension signature verification in ESR versions of firefox. https://github.com/NixOS/nixpkgs/blob/master/doc/builders/packages/firefox.section.md describes the thing in more detail.

Sadly, the standard package repository for NixOS doesn't have the extensions themselves (maybe it should?), so one can't benefit from the slower uptake etc.

@malcircuit Nit(?): There are things in nature that are precise and repeatable: first example that comes to my mind is that all electrons are identical, second is that differences in energy between different excitation levels are always nearly the same.

What's the green line (and why does the "debris" line end there)?

@LukaszHorodecki czy nie jest tak, że też nie można agitować wobec uczniów?

@johncarlosbaez

I can't think of any book to recommend, other than maybe statistics textbooks for nonmathematicians.

There's are two things that come to mind: formulating questions precisely and concepts in simple statistics and hypothesis testing. Former I'd expect judges to be good at anyway (maybe modulo not having the expectation that things that should always be true should actually literally always be true). In later I'd expect the most important part to be understanding of distinctions between concepts that are tied together by base rates (e.g. conditional probabilities in different directions).

@lcamtuf All five users of gmock matchers in gtest? :)

@lcamtuf It is pretty common (gtest, Haskell, Prolog and Agda come to mind).

@TechConnectify

How do these losses compare to gearbox-related losses (as in, losses in the gearbox and losses due to operating the engine at suboptimal RPM for the load)?
