03:14:42 <Cale> I don't think so
03:20:13 <Cale> It was one character per instruction in a 2D grid, and when the program was first loaded, the orthogonally adjacent connected bunches of instructions would be determined and grouped together into "rafts", and then there were instructions which would cause the raft they were in to move up/down/left/right, I think so long as they weren't bumping into another raft (so they could steer themselves around against the whitespace background)
03:21:08 <Cale> and so two rafts could come together to allow control to flow from one to the other, and then perhaps separate again later

10:11:47 <gamemanj> so apparently my program thinks zzo38's munching squares program likes the value "d2" a lot.
10:12:17 <gamemanj> And has thus peppered all the "potential jump / potential copy" lists with various placements of d2.
10:12:31 <gamemanj> And has thus given up on trying to use immediate values.
10:19:21 <gamemanj> It seems it's found an excuse, somewhere, to pepper memory with D2.
10:46:14 -!- tsumegirl has changed nick to izabera.
10:50:12 <gamemanj> Programs with > 2,300 instructions tend to run into problems due to the memory required for storing the range of possible states at a given instruction, even with some accuracy-vs-speed tradeoffs towards speed (said optimizations likely being the cause of the 'd2' problem)

10:56:49 <gamemanj> It seems the tracer only works relatively well on structured programs that do not use speed-code. i.e. None of them.

11:00:04 <hppavilion[1]> An extreme case is the Toccata Grande Cromatica by early-19th-century American composer Anthony Philip Heinrich, which uses note values as short as 2,048ths; however, the context shows clearly that these notes have one beam more than intended, so they should really be 1,024th notes.[4]
11:01:20 <gamemanj> hppavilion[1]: yay for mangled wording!
11:02:15 <gamemanj> ...well, you were commenting on the "really" being there when it's a statement of opinion, correct?
11:03:28 <hppavilion[1]> gamemanj: I was pointing out that, for any reasonable duration of a whole note, the difference between a 2048th and 1024th note is imperceptible, AND it's impossible to reliably play either one anyway
11:04:03 <gamemanj> why on earth would someone use such values, then?
11:04:53 <hppavilion[1]> gamemanj: The article is expressing how the use of 2048th notes is pretty extreme, but that there is one extra flag so it's actually 1024th notes, which is somehow more reasonable
11:05:16 <hppavilion[1]> gamemanj: Keep in mind, a whole note is 1 second iirc, meaning a 1024th note is less than a millisecond long
11:05:58 <gamemanj> Then it would sound like a click.

11:26:31 <int-e> "docker" has a totally different philosophy.
11:26:44 <int-e> also I don't quite get what the point of docker is...
11:26:55 <int-e> ...since it fails at proper isolation.
11:28:12 <gamemanj> Here's how HackEgo seems to work: 1. command gets entered in 2. UML with "bare" initrd (could even be using ASM and syscalls) and extremely minimal setup boots, 3. The init performs magic (TM) and starts the command.
11:29:06 <gamemanj> idea: cat /proc/1/exe > extracted-init
11:29:18 <gamemanj> though it'll probably fail due to permissions. :(
11:29:39 <int-e> But I get the point where they say that every component brings its own dependencies and therefore will not change its behavior when transferred betwenn hosts. No missing libraries on the host system, no conflicting versions... all coupled with the attitude that bandwidth and storage are essentially free.
11:30:04 <int-e> (I'm sure it sometimes goes wrong when you change kernel versions.)
11:33:49 <gamemanj> (Well, if syscalls get dropped or are made incompatible, it would probably go wrong. But usually versioning problems stay in userland AFAIK.)
11:37:52 <int-e> gamemanj: you could always look at source code: https://bitbucket.org/GregorR/umlbox/src/tip/init.c
11:42:11 <int-e> hah. echo init | cpio -H newc -o | gzip -9c > umlbox-initrd.gz ... that's quite minimal.
11:42:44 <hppavilion[1]> It's basically just a half note where the ellipse is a "©"
11:43:03 <gamemanj> int-e: Presumably init is linked statically, then?
11:43:09 <int-e> gamemanj: of course.

16:03:36 <Cale> fizzie: In Javascript's string notation, escaping any character which isn't otherwise special results in just that character.
16:04:08 <fizzie> It's specifically just the /, not any other character.
16:04:15 <Cale> Oh, that's interesting.
16:04:31 <Cale> I would have expected them to just steal the string syntax wholesale.
16:04:34 <fizzie> Although that might still be the underlying reason, if (for some reason) there's a lot of use of "\/" in JS strings.
16:04:38 <fizzie> http://www.json.org/string.gif
16:05:34 <fizzie> Maybe it's to make / not jealous of \.
16:07:28 <FireFly> fizzie: oh, that explains why I've seen "\/" a lot in JSON

19:13:42 <impomatic> Is there a nice bit-twiddling hack to extend a bit to fill all higher bits in an int?
19:14:44 <impomatic> E.g. 0000001010101010 -> 1111111010101010 extending bit 10 to fill the higher bits.
19:17:56 -!- gremlins has joined.
19:19:14 -!- Reece` has quit (Ping timeout: 260 seconds).
19:21:14 <fizzie> impomatic: It's not *that* nice, but you could make one out of the (mostly obvious) https://graphics.stanford.edu/~seander/bithacks.html#RoundUpPowerOf2 by leaving out the v--;/v++; and adding a orig_v |= ~v; at the end.
19:22:49 <fizzie> (It'd just go 0000001010101010 -> 0000001111111111 -> 1111110000000000 -> 1111111010101010 in the obvious manner.)
19:25:07 <impomatic> Maybe better to stick with IF (numb & 0x400) {numb -= 0x800} or whatever I'm currently using.
19:26:27 <fizzie> Oh, you had a particular position you want? I assumed a general "invert all leading zeros left of the most significant set bit".
19:28:33 <fizzie> For the fixed-position case, "(numb << K) >> K" is possibly the simplest thing to do, but only if you happen to have access to a >> that's reliably an arithmetic right shift.
19:30:31 <fizzie> Standard C's >> is implementation-defined for a signed, negative number, though I think the most common implementation is an arithmetic shift.
19:31:07 <fizzie> Not much of an improvement over the if, though.
19:32:31 <impomatic> No, I'll stick with if, but will test it out of curiosity :-)
