07:58 timotimo JimmyZ: i'm looking through moarvm issues on github and i've found your issue 150; a script to generate a sphere as a pgm. i don't understand the script, though. it has "until start { ... } { write output data; sleep 1 }" in it, that's quite weird, IMO
08:00 timotimo holy crap, Blob.new: @pixels is CRAZY slow
08:02 timotimo ah, that's why.
08:13 JimmyZ timotimo: the code is not mine, I saw it in the irc log
08:14 timotimo mhm
08:14 timotimo ah, i'm not sure if i can actually get away with making Blob.new: @foo faster using nqp::splice

09:03 dalek MoarVM: 4a35f2c | timotimo++ | src/io/syncfile.c:
09:03 dalek MoarVM: handle files where stat falseley reports 0 bytes size
09:03 dalek MoarVM: review: https://github.com/MoarVM/MoarVM/commit/4a35f2cc3d
09:48 arnsholt What's the bottleneck, OOC? Getting data out of @pixels, or into the Blob?
10:10 timotimo oof, good question
10:11 timotimo the thing is, the original script i was looking at could benefit a whole lot just by using a Buf[int8] instead of a regular array for this
10:11 timotimo in that case, there was no need to create a blob in the first place

11:21 arnsholt Right, right
11:21 arnsholt Once again, it turns out that choosing the right data structure is kind of important =)

17:04 timotimo jnthn: something has been bugging me: we have utf8-c8 to allow things to roundtrip through Str that potentially contains binary garbage, because filesystems may allow filenames with "anything but slash or null" in them ... but how do we roundtrip given that we do NFC and then NFG in order to create a Str?
18:14 brrt joined #moarvm
18:14 brrt good *
18:14 brrt is jnthn available?
18:22 brrt i'm.. having a nasty issue
18:23 brrt conceptually, at least
18:24 brrt in OSR, and deopt, and various other purposes, i may want to put a label directly before of after an instruction
18:26 brrt hmm
18:26 brrt maybe it isn't a problem after all
18:28 brrt it just, *sigh*, requires me to rework some of the funky decisions i made in the original jit labelling code
18:29 brrt thereby demonstrating that i'm an idiot
18:30 arnsholt Probably not =)
18:30 arnsholt Just that compilers are hard
18:51 brrt yeah, and people naive :-)
18:52 brrt except that i have a vested interest in people believing that compilers are not, in fact, hard
18:52 brrt and they aren't
18:52 brrt you just have to do not the stupid things i did
18:52 brrt :-P
18:54 brrt anyway, i'd like everyone to believe it is really simple, so they all feel they can help out
18:54 brrt obviously ending with me doing nothing
18:55 * brrt afk now
