Conversation with #inferno at Tue Jan 18 02:56:46 2011 on powerman-asdf@irc.freenode.net (irc) (02:56:57) base2design: (reading the inferno docs on benchmarking, but may resort to "sys->print" debugging unless there's another best practice the irc viewers can suggest) (03:52:24) caerwyn left the room (quit: Quit: Colloquy for iPad - http://colloquy.mobi). (04:47:26) cbj1 left the room (quit: Ping timeout: 240 seconds). (06:33:25) sl_0 [~sl@68-179-130-17.bsr-c9-d1.evv.dhcp.sigecom.net] entered the room. (06:35:18) sl left the room (quit: Remote host closed the connection). (06:35:49) sl_0 is now known as stanleylieber (06:35:57) stanleylieber is now known as sl (07:51:08) robot12 [~KAZZhilki@proxy10.ts.fujitsu.com] entered the room. (08:34:41) Gegemon [~ynv@mx1.airis.ru] entered the room. (09:08:59) bvalek2 [c3e41484@gateway/web/freenode/ip.195.228.20.132] entered the room. (09:42:55) mjl-: base2design: prof and wm/prof are quite easy to use. perhaps in combination with using "time" or some debug prints that print time deltas (10:16:26) Fish left the room (quit: Quit: So Long, and Thanks for All the Fish). (10:16:47) Fish [~Fish@exo3753.pck.nerim.net] entered the room. (10:16:59) Fish left the room (quit: Client Quit). (10:18:33) Fish [~Fish@exo3753.pck.nerim.net] entered the room. (11:06:14) mjl-: base2design: i can think of a few reasons why it isn't zippy (11:06:50) mjl-: it could be hget's stacking of file descriptors (file2chans), leading to more memory copies than necessary. (11:07:05) mjl-: but that would really only show on pretty high throughput speeds (11:07:25) mjl-: i don't think the encryption part is a bottleneck, that's all c code. (11:08:51) mjl-: perhaps the connection set up is not the fastest. i think the ssl module has a cache for ssl connection states. you could try requesting the same file multiple times in a row (in a single modified hget instance) and see if the later requests are faster. (11:08:56) mjl-: that would hint at connection set up (11:09:02) mjl-: perhaps i could also run some tests :) (13:08:56) MrWGW- [MrWGW@74.124.192.92] entered the room.

(16:08:31) base2design: wow... how did i miss "prof"... i saw mprof but totally ignored that lookman showed prof. (16:09:01) MrWGW- [MrWGW@74.124.192.92] entered the room. (16:17:51) eno__ [~eno@adsl-70-137-134-172.dsl.snfc21.sbcglobal.net] entered the room. (16:20:31) eno left the room (quit: Ping timeout: 240 seconds).

(20:51:54) mjl-: is there something like mntgen, but that generates files? (20:52:05) mjl-: now i cannot bind a file on something generated by mntgen (20:52:25) mjl-: perhaps a fixed number of files/dirs would be good to, like aux/stub on plan 9 (20:54:58) mjl-: also, does someone know good free alternatives to the charon fonts? (21:05:14) bvalek2 left the room (quit: Quit: Page closed). (21:25:02) KillerX [~anant@nat/mozilla/x-wgkycutpspqpmgoy] entered the room. (21:32:26) mjl-: bitmap fonts suck... (21:33:03) mjl-: wasn't there a file server for plan 9 that served bitmap files, generating them on the fly from ttf fonts? (21:33:31) mjl-: ah, p9p, fontsrv(4) (21:35:10) mjl-: you wouldn't get any of the kerning features, but well (21:35:57) mjl-: oh, but fontsrv serves files from the host os (21:36:00) mjl-: we have freetype! (21:40:11) vsrinivas: we do. (21:40:14) vsrinivas: and Vera. (21:41:34) base2design [~basedesig@166.137.13.51] entered the room. (21:42:12) mjl-: we do? (21:42:21) mjl-: vera is the font right (21:42:36) mjl-: but it's not usable by "normal" inferno apps, e.g. using tk (21:42:37) mjl-: hi base2design (21:42:56) base2design: Hey (21:43:33) base2design: I haven't dug into the specifics yet, but as a high-level co (21:44:57) base2design: Comparison could you hget https://mail.ic-electronic.com/images/DENM001.gif (21:49:49) base2design: Takes 136 seconds on emu under osc (21:50:14) base2design: 133 sec on x86 Linux box (22:52:38) base2design_ [~basedesig@166.137.14.161] entered the room. (22:54:08) base2design_: I just ran emu/hget on some "big iron" and experienced the same run-time... Which makes me think this is a network timeout of some kind. (22:56:24) base2design left the room (quit: Ping timeout: 246 seconds). (22:56:25) base2design_ is now known as base2design (23:16:14) Fish- left the room (quit: Ping timeout: 240 seconds).

(00:23:25) base2design [~basedesig@166.137.12.166] entered the room. (00:30:32) mjl-: base2design: i should've notice it before (00:30:41) mjl-: try hget with options: -h connection close (00:30:43) mjl-: it is a timeout (00:31:13) mjl-: it has to do with ssl's treating the read function as readn, i.e. it only returns when the buffer is full or during eof (00:31:41) mjl-: the header "connection: close" causes the server to close the connection when all data is sent, causing ssl's read to return (00:44:09) Fish- left the room (quit: Quit: So Long, and Thanks for All the Fish). (01:03:50) base2design_ [~base2desi@97-80-161-40.dhcp.gwnt.ga.charter.com] entered the room. (01:32:46) caerwyn [~caerwyn@c-98-217-102-21.hsd1.ma.comcast.net] entered the room. (01:53:55) mjl-: hi base2design, caerwyn (01:54:38) caerwyn: mjl-: Hi (01:55:21) caerwyn: Doing a little reading, looking for inferno projects, (01:55:49) caerwyn: The unmanaged internet architecture looks interesting. (01:57:00) mjl-: haven't heard of it (01:57:02) vsrinivas: caerwyn: i picked up your IPN oscilloscope widget, btw (01:57:48) vsrinivas: i've got it reading IAF and WAV and am printing short-time frequency data. (01:58:07) vsrinivas: (but haven't figured out how to make a 2nd window in Tk yet, so no spectrum) (01:58:13) caerwyn: Is that what the dft was for? (01:58:33) vsrinivas: no (01:58:34) caerwyn: I dont think the inferno fft ever worked well for me. (01:58:46) vsrinivas: i didn't even try it, though. (01:58:52) vsrinivas: (the inferno one) (01:59:07) vsrinivas: umm, would perhaps be nice to include fftw with inferno? :D (01:59:15) vsrinivas: and wrap it as the FFTs module is? (02:03:44) caerwyn: Looked up fftw. Yes, but pity the limbo one doesnt work. (02:11:53) vsrinivas: yea, hmm. (02:12:12) vsrinivas: did you ever have any plans for your scope program? (02:12:16) vsrinivas: *further plans? (02:21:02) MrWGW- left the room (quit: Ping timeout: 240 seconds). (02:53:27) The account has disconnected and you are no longer in this chat.
