00:07:25 <salpynx> Thanks HackEso! You just helped me troubleshoot a work-related problem involving UTF-8 encoded Tamil and binary MARC (1960s binary format for library) records. Sharing because that's pretty esoteric, and surprising since joining #esoteric was more for procrastination than getting things done.

00:10:16 <zzo38> I cleaned the computer; that seemed to to reduce the CPU temperature by 7 kelvin, although the motherboard temperature and graphics temperature seem to be the same as before. The room temperature seems to have increased, although that might be due to something else. (The room temperature as measured by a red temperature)
00:10:22 <salpynx> FTR, no Unicode was incorrectly encoded, I needed confirmation I was locating utf8 byte strings within a binary format correctly. The problem was not because of Unicode :)
00:16:55 <salpynx> Room-temperature computing is a worthwhile goal. Definitely harder for some computers.
00:23:16 <zzo38> Is it expected that the mother board temperature should match the room temperature?

00:33:02 <esowiki> [[Talk:The Past]] https://esolangs.org/w/index.php?diff=76130&oldid=76075 * Caenbe * (-84) Done.
00:44:18 <salpynx> ... I was facetiously referencing room-temperature quantum computing efforts, but I guess motherboard temperature can't be _exactly_ room temp. If so it'd be just computing brownian motion, and no work will be getting done.
00:45:16 <zzo38> The motherboard temperature is only slightly higher than the room temperature; the CPU temperature is higher than that.
00:49:15 <salpynx> oh, I thought you loosely meant processor when you said 'motherboard'

06:44:38 <int-e> I'm finding https://pwmarcz.pl/kaboom/ so addictive.
06:55:18 -!- salpynx has quit (Remote host closed the connection).
06:55:22 <shachaf> Finally a reasonable game of mine's weeper.
06:58:38 <int-e> it's a devious one... rather than getting frustrated at the game for making you guess you get the chance of getting frustrated at yourself for missing forced conclusions (of various degrees of obviousness)
06:59:31 <int-e> Oh and if you find the presets boring, you can increase the board size.
07:00:06 <int-e> (The link isn't new, I believe I found this game via this channel a few years back.)
07:00:34 <int-e> But maybe it was somewhere else. We definitely discussed it here.
07:04:45 -!- clog has quit (Ping timeout: 256 seconds).
07:05:34 <int-e> One slightly unfortunate feature is that when you're left with a 50/50 choice that can provably never go away you still have to progress on the rest of the board until you're forced to guess there as well before you are allowed to hazard a guess.
07:12:54 -!- LKoen has joined.
07:13:35 <int-e> The ultra-violence mode is pretty cute too... not the hardest, but pretty different from ordinary minesweeper because easily half of the moves are of the forced guess type.
07:14:12 <int-e> which at least in my case leads to very non-random looking boards in the end.
07:15:30 <int-e> https://int-e.eu/~bf3/tmp/uv.png ... I wonder how much strategy this reveals :)
07:16:45 <shachaf> Oh, that's interesting, you can infer things about how people played from a completed board?
07:17:12 <shachaf> Also look at how GPT-3 has mastered category theory: https://gist.github.com/ekmett/11a0e1f49b73a2feab287373ddaf68cd
07:17:17 <shachaf> In particular the ending.
07:18:48 <shachaf> Hmm, the nonlocality of this is kind of bizarre.
07:19:04 <int-e> shachaf: maybe if you have more than one sample... https://int-e.eu/~bf3/tmp/uv2.png
07:19:22 <shachaf> I mean, if I reach an isolated corner that needs guessing, I shouldn't guess immediately (which would be the time-saving strategy in regular Minesweeper), I should save it until I have to guess. Right?
07:19:41 <int-e> you'll see that there are many more straight lines than there should be... and that's because of a preference in how I'm guessing.
07:20:03 <int-e> shachaf: right
07:20:29 <shachaf> That makes sense, I was doing that too.
07:28:30 <rain1> oh wait
07:28:31 <rain1> i shouldn't read this
07:28:38 <rain1> i find the yoneda lemma hard enough already
07:28:52 <rain1> i don't want to get misled by some AI generated version is slightly wrong..
07:29:10 <rain1> that ending was 100
07:35:05 <int-e> shachaf: I suspect that Kaboom can seriously mess with somebody who's actually good (i.e. fast) at regular minesweeper.

09:05:51 <int-e> Some weighted average maybe? Ironically you probably care most about the (literal) hotspots.
09:11:17 <shachaf> Hmm, rr has ptrace emulation, that's pretty fancy.
09:11:33 <shachaf> I mean that it uses ptrace but it can trace a program that also uses ptrace on the same process by proxying the ptrace calls.
09:11:33 <int-e> `? rr
09:11:36 <HackEso> rr? ¯\(°​_o)/¯
09:11:46 <shachaf> https://rr-project.org/
09:12:18 <shachaf> It's a program that records program execution and then lets you replay it in a debugger.
09:12:33 <int-e> oh, fancy
09:12:48 <shachaf> Mostly by remembering the state of memory etc. and the results of every system call, so it can fake responses to those system calls.

09:13:28 <shachaf> record replay? I don't know.
09:13:52 <int-e> pffft, chaos mode
09:14:49 -!- kspalaiologos has joined.
09:15:59 <shachaf> Maybe I should write a debugger. How hard can it be?
09:21:48 <int-e> the usual
09:22:04 <int-e> easy (or, at least, fun) to get started, impossible to finish
09:33:23 -!- hendursa1 has quit (Ping timeout: 240 seconds).
09:37:26 <int-e> That may be too optimistic though, there's quite a bit to do before you can even do *something* beyond tracing syscalls (which is *relatively* easy)... lots of poking around in the subject's memory, lots of platformspecific things right from the start.
09:38:14 <shachaf> Yes, you would need to get DWARF data to do most things people want from debuggers.
09:39:37 <shachaf> Or PDB or something, I guess. They're all complicated.
