OT(?): How do you avoid every reader having to do some amount of work to figure out if they're supposed to deallocate something due to a resize downward? (Or do you mean only resizes upward?)

@grrrr_shark

Small nit(?): you probably meant that he need not feel awkward. At least for some people it's hard to stop feeling awkward by conscious choice, and trying to do so is not necessarily useful (a.o., because failure to do so might cause feelings of guilt).

(This makes me wonder how similar social expectations around expressing awkwardness are to those around being emotional: both feel like things people would frown upon in public without any good reason I can see.)

@whitequark what would you use a sheet for (and how would you machine it?)

@whitequark I vaguely remember reading in a Konrad Lorenz book that prey animals very rarely if at all fight for dominance, so don't have a concept of stopping a fight when the opponent submits, and that this leads to problems with keeping some kinds of bird in enclosures (they can't signal submission, nor can escape, because enclosure, so they are likely to injure each other significantly if a fight develops).

Kiedy się owa była zaczęła?

@ruuda It's not the increased pressure from vapor that counteracts ~anything as long as the liquid is incompressible: it's just that more of the liquid evaporates. I agree about that case, and at some point the trend has to reverse, because eventually all the water will boil (or, if the density in the container is too high, we will reach the critical conditions first).

Let's assume we have a fixed container filled with some amount of a liquid and its vapor. If we heat it up, obviously the fraction of mass that's in vapor form will increase (being in gas is higher energy state, fraction of stuff that's in a higher energy state increases as energy increases in a thermodynamic equilibrium; I might be wrong if there's something really wonky going on with surface tension). What about volume fraction? At first glance it seems that it can change in either direction.

https://en.wikipedia.org/wiki/Nusselt_number#Dittus%E2%80%93Boelter_equation says:

> n = 0.4 for the fluid being heated, and n = 0.3 for the fluid being cooled.

WTAF. Why do we have different power laws for heat transfer between a solid and liquid when the flow is turbulent _depending on the direction of heat transfer_? I can't think of any simple mean field approximation of the process that would yield that.

@Nonya_Bidniss

Ah, I might have seen some other variants of the same concept (I saw them in toilets in Japan with no rhyme or reason that I could discern as to which ones would have them and which would have a separate sink).

@Nonya_Bidniss

(Potentially OT) Huh, I thought the point of those is saving water and encouraging people to wash hands after using the toilet. How do these prevent vandalism (of the sink or of the toilet?) and/or self-harm?

@simontatham

So, we should run away from shells (which separate paths in $PATH with a colon, which is a perfectly valid path of a directory name)?

@timorl I think that was the case only until https://www.bj.admin.ch/bj/de/home/gesellschaft/zivilstand/infostar/infostar-ng.html

@filippo @whitequark @glyph

value mismatch != wrong; if you equate the two you will lose the people who care about the distinction (either due to their approach to communication, or because e.g. they believe communities that claim that other values are wrong by fiat are likely to be/become hostile).

For banning for value mismatch not to seem arbitrary the values have to be clearly visible to everyone (incl. bystanders), too. whitequark's codes of conduct are IMO an example of being very clear on them.

@CppGuy @0xabad1dea

Unless the GC somehow takes into account memory refresh cycle? (Though I'd expect that to be unlikely.)

@0xabad1dea if I was the only person in the audience and could ask questions I would love this presentation. Alas, then it wouldn't have to be a presentation.

@badastro

This is very close to a plot point of Perihelion Summer.

@_thegeoff So you'd want a laptop, minus the human interfaces (in both directions), but still with a battery? If you didn't want the battery, then lots of single board computers with an enclosure around them would match these requirements, and some of them might even match all the unstated requirements (perf, amount of storage, kinds of network interfaces available, ...). It's obviously a much less well supported setup than a laptop, though.

If you mean laptop _with_ a screen, but without input devices, then you might find form factor of Novena (the ~laptop) interesting.

@mcc

> my rule is only "at most one writer"

So, any number of readers *and* at most one writer?

I don't quite see how this restriction helps with memory management (or rather, helps with statically ensuring that memory management is correct) over allowing multiple writers but requiring lifetimes of all references to ~match.
