02:26:49 <shachaf> How should coroutines work if you wanted them to be really efficient?
02:26:57 <shachaf> I'm thinking about it and the details are actually tricky.
02:27:03 <shachaf> I wonder whether anyone's done it properly.
02:28:16 -!- xkapastel has quit (Quit: Connection closed for inactivity).
02:39:26 <kmc> shachaf: well, in some cooperative RTOSes, you are only allowed to yield in main()
02:39:34 <kmc> (or some rule morally equivalent to that)
02:39:58 <kmc> so there's a tight bound on the per-coroutine stack size
02:40:13 <kmc> anyway, can you elaborate?
02:42:06 <shachaf> So there are a bunch of different use cases, but let's say we're talking about asynchronous I/O.
02:42:37 <shachaf> If you want to write a complicated thing that does asynchronous I/O, you can write a state machine by hand.
02:42:55 <shachaf> Or you can make small cooperative threads with full stacks of their own.
02:43:12 <shachaf> Which is nice but kind of wasteful with respect to memory use and unnecessary cache misses and so on.
02:43:53 <shachaf> If you have compiler support, you can maybe have it generate something like the state machine for you, and do liveness analysis and everything and make it nice.
02:44:00 <kmc> yeah
02:44:03 <shachaf> But I'm wondering about the details of how it should work.
02:44:18 <shachaf> Especially when you have asynchronous things that call other asynchronous things and so on.
02:47:02 <shachaf> The coroutine state machine state is effectively a second stack, used only for async state
02:47:21 <kmc> yeah
02:47:49 <shachaf> This is good because the stack is smaller and you only use it for things that really need to be saved (your regular stack is in cache so you don't want to switch stacks completely).
02:48:08 <kmc> the question then is could you sensibly tell the compiler which things don't need to be saved
02:48:21 <kmc> or would that be a nightmare
02:48:57 <shachaf> It should be able to figure it out?
02:49:22 <shachaf> If you tag your async functions then only their variables that are saved across yield calls need be saved.

20:29:45 <Taneb> Can someone recommend me a new rubik's cube
20:33:15 <int-e> . o O ( get a megaminx )
20:36:37 <Taneb> int-e: I'm thinking something with an obvious isomorphism to the original
20:38:19 <int-e> Uh, one can buy 17x17x17 cubes now? Crazy...
20:38:47 <int-e> (only EUR 1.3k)
20:39:41 <int-e> Anyway, I know too little. Stickerless is nice but that doesn't really narrow it down much.
20:41:26 <int-e> isomorphic, eh... there's the mirror cube variant (which I imagine would be really awkward to handle)
20:42:39 <int-e> But apparently that doesn't stop people from offering speed cubing variants of those... "Shengshou Mirror Speed Cube"
20:43:15 <int-e> https://images-eu.ssl-images-amazon.com/images/I/512Tno1siWL._AC_US218_.jpg ... I guess that's the standard checkerboard pattern
20:45:33 <Taneb> int-e: basically I'm looking for a 3x3x3 cube that isn't a really stiff one I bought in a toy store whose stickers are coming off
21:03:03 <b_jonas> Taneb: ask #rubik on this irc network, they can give good advice about that
21:04:25 <b_jonas> Taneb: I bought two decent cubes last year, the one I prefer is "Quyi TheValk 3"
21:04:50 <b_jonas> note that "3" is the version number, not size

21:39:02 <kmc> oh i have a mirror cube!
21:39:06 <kmc> (or had; I haven't seen it in a while)
21:39:22 <kmc> it is definitely more difficult to handle
21:39:26 <kmc> and it looks way cool
21:40:00 <kmc> I first encountered one while drunk at a New Year's party and it became an object of obsession for a little while
21:42:22 <shachaf> I think I first encountered one at your house.
21:47:54 <Taneb> My brother's girlfriend got me a cube whose faces change colour depending on the light
22:16:10 <kmc> Taneb: that's neat
