| 00:00.11 | lurgyman | that mdstat's time remaining is impressive, what with all the speed fluctuations |
| 00:01.04 | kergoth | APR_SAVE_THE_ENVIRONMENT. makes it sound like their configure script is involved in saving the rainforests or something |
| 00:01.07 | kergoth | i really need to go home |
| 00:01.28 | lurgyman | heh |
| 00:01.35 | lurgyman | sounds like our tuition & fees breakdown |
| 00:02.08 | lurgyman | shouldn't people who have a positive net worth be paying for things like that? |
| 00:03.24 | lurgyman | besides, wolves would be redundant with animals like the lynx and mountain lion :) |
| 00:05.02 | lurgyman | hmm, looks like the tomato sauce is doing that for him |
| 00:05.14 | kergoth | hehe |

| 00:05.40 | carpman | how many square feet? |
| 00:05.52 | lurgyman | 2 |
| 00:06.09 | lurgyman | give or take some degree of geometric precision |
| 00:06.17 | carpman | hmm |
| 00:07.38 | captain_proton | hmm |
| 00:07.52 | captain_proton | darth_mall: an episode or 2 of something to distract me from biting my fingernails at this raid sync? :) |
| 00:08.05 | darth_mall | captain_proton: I'd love to, but I have way too much homework due tomorrow |
| 00:08.15 | captain_proton | fine fine |
| 00:08.51 | captain_proton | ew |
| 00:09.02 | darth_mall | yup |
| 00:09.15 | darth_mall | it's like 10 pages worth of which I've done like 1.5 |
| 00:09.44 | darth_mall | damn, I am so addicted to Happy End of the World for some reason |
| 00:09.58 | captain_proton | 'tis a good song :) |
| 00:10.08 | darth_mall | no, I mean the album |
| 00:10.13 | captain_proton | oh, yeah |
| 00:10.17 | captain_proton | well, 'tis a good album too :) |
| 00:10.21 | darth_mall | ^^ |
| 00:11.50 | darth_mall | w00t! |
| 00:11.57 | darth_mall | 100 pts on my first P.L. assignment |
| 00:12.03 | lurgyman | :) |
| 00:12.07 | lurgyman | yay for darth_mall! |
| 00:17.27 | lurgyman | teehee |
| 00:18.01 | darth_mall | ^^ |
| 00:21.26 | lurgyman | hmm |
| 00:21.44 | darth_mall | oooh, captain_proton is listening to my favorite Little Birdy song |
| 00:27.11 | lurgyman | mwa ha |
| 00:27.19 | purple_cow | grrrr |
| 00:28.09 | darth_mall | well... I guess it makes sense because it can also mean 'appearance'... but still |
| 00:34.13 | captain_proton | evolution takes too damn long to compile |
| 00:36.49 | lurgyman | yep |
| 00:37.02 | lurgyman | yay, 50 minutes til raid syncage completes... woowoo |
| 00:37.13 | captain_proton | maybe :) |
| 00:37.20 | captain_proton | could be a few hours, could be never :P |
| 00:37.46 | captain_proton | around 20% or so navi was doing this abort/reset thrash |
| 00:37.53 | captain_proton | which really has an impact on sync performance |
| 00:37.58 | captain_proton | (drops it down to about 50K/s) |
| 00:38.19 | lurgyman | :( |
| 00:38.36 | lurgyman | but yay for it being up again, for the time being :) |
| 00:38.46 | captain_proton | yeah |
| 00:38.57 | captain_proton | i'm starting to think that maybe the power supply is undervoltaging or somesuch |
| 00:39.20 | captain_proton | but at least power supplies are dirt cheap nowadays |
| 00:40.33 | lurgyman | good thought |
| 00:40.33 | lurgyman | how much is in there now? |
| 00:40.56 | captain_proton | its a 550W |
| 00:41.52 | darth_mall | lol |
| 00:42.00 | darth_mall | they actually use a kanji for 'karaoke' |
| 00:42.22 | captain_proton | darth_mall: karaoke is a very important part of japanese culture :) |
| 00:42.37 | darth_mall | I know, but they combine kanji and katakana |
| 00:42.41 | darth_mall | you *never* see that |
| 00:43.04 | darth_mall | because katakana is for onomatopoeia (sure I spelled that wrong) and foreign words |
| 00:43.40 | lurgyman | captain_proton: so, you're thinking maybe get a 2nd? :) |
| 00:44.08 | captain_proton | lurgyman: well, if we're still having funky things happen after we swap wasabi & navi around, then yeah, try replacing it |
| 00:44.15 | captain_proton | or at least try measuring its output |
| 00:44.19 | lurgyman | yep |
| 00:44.34 | lurgyman | hmm |
| 00:44.42 | lurgyman | do we know how much one of those drives uses? |
| 00:44.50 | captain_proton | the seagates are 55W, i think |
| 00:45.05 | captain_proton | er, technically 55VA :) |
| 00:45.13 | captain_proton | i'd bet the IBMs are a good bit more |
| 00:45.24 | lurgyman | :) ok |
| 00:47.27 | lurgyman | so if there are 13 drives in there (right?) then they'd be trying to draw at least 55W*13 = 715W |
| 00:47.46 | lurgyman | ..which seems a bit higher than our current capacity, doesn't it? |
| 00:48.01 | lurgyman | and that's not counting anything else on the motherboard |
| 00:48.06 | captain_proton | ooh, http://story.news.yahoo.com/news?tmpl=story&cid=519&e=2&u=/ap/20040126/ap_on_re_us/patriot_act |
| 00:48.31 | captain_proton | lurgyman: no, VA != W in all cases :) |
| 00:48.46 | lurgyman | oh? |
| 00:49.00 | lurgyman | by definition P=iR |
| 00:49.02 | lurgyman | er |
| 00:49.05 | lurgyman | p=ir |
| 00:49.07 | captain_proton | lurgyman: the old navi was working fine with 6 disks plus the motherboard and stuff on a 350W |
| 00:49.13 | captain_proton | lurgyman: only in ideal circuits |
| 00:49.33 | carpman | yeah, ohm's law dosn't count for tolerance :) |
| 00:49.43 | lurgyman | er |
| 00:49.44 | lurgyman | p=iv |
| 00:49.46 | captain_proton | its really just a technicality, since hard disks are close enough to linear for W to work |
| 00:49.51 | lurgyman | indeed |
| 00:50.07 | lurgyman | p = iv always, it's a definition of power |
| 00:50.11 | lurgyman | ohm's law doesn't enter into it |
| 00:50.50 | captain_proton | that holds true for linear circuitry |
| 00:50.57 | lurgyman | and nonlinear circuitry |
| 00:51.12 | captain_proton | uhm |
| 00:51.17 | lurgyman | ohm's law is the one that applies to linear circuitry |
| 00:51.30 | lurgyman | i and/or v can be any function |
| 00:51.30 | captain_proton | not the last time i checked, but if you insist |
| 00:51.41 | lurgyman | not necessarily linear |
| 00:52.13 | lurgyman | don't make me get all dimensional analysis on your ass ;) |
| 00:53.21 | lurgyman | that's like saying a meter times a meter isn't a square meter for a nonlinear function that gives meters :) |
| 00:53.36 | lurgyman | ...then gets multiplied together... |
| 00:54.10 | lurgyman | still |
| 00:54.33 | lurgyman | captain_proton: with 6 drives in there, if they wanted around 55W each, that's still only 330W worth |
| 00:55.06 | captain_proton | lurgyman: i may be misremembering |
| 00:55.16 | lurgyman | k |
| 00:55.20 | captain_proton | plus whatever figure that was would be max draw |
| 00:55.20 | lurgyman | well, we should talk to scanline :) |
| 00:55.26 | lurgyman | yeah |
| 00:55.33 | lurgyman | that we'd run into during, say... syncs... |
| 00:55.45 | lurgyman | or at least, near |
| 00:56.12 | captain_proton | we shouldn't even come close |
| 00:56.16 | captain_proton | seeing as we're using software raid |
| 00:56.48 | captain_proton | its only writing ~10M/s |
| 00:57.02 | captain_proton | whereas these drives can probably write closer to 50 |
| 00:57.07 | lurgyman | sure, but the mechanical parts are still moving pretty fast there |
| 00:57.16 | lurgyman | which should be what eats up the power |
| 00:57.27 | lurgyman | at least, i would think so |
| 00:57.32 | captain_proton | the heads aren't moving very fast at all, since the blocks are right next to each other |
| 00:58.09 | lurgyman | but dunno... you don't have to get very close to 715V before you've already passed 550V, especially with the motherboard and cpu and pci stuff all munching power too :) |
| 00:59.00 | lurgyman | oh no! |
| 00:59.04 | lurgyman | er |
| 00:59.07 | lurgyman | s/V/W/ :p |
| 00:59.27 | lurgyman | yay for dinner |
| 01:04.13 | lurgyman | hf :) |
| 01:11.34 | CIA-5 | 03brandon * r2069 10mice/rebuild/applets/submit/question.java: Does this work? |
| 01:24.30 | *** join/#tacobeam lurgidob (~lurgyman@navi.cs.colorado.edu) |
| 01:24.37 | darth_mall | hi lurgidob! |
| 01:24.48 | lurgidob | darn, didn't fix it :) |
| 01:24.48 | darth_mall | hehe |
| 01:24.48 | scanline | hrmph |
| 01:24.55 | lurgidob | no tab-completion happiness quite yet |
| 01:24.57 | lurgidob | mornin sunshine :) |
| 01:24.58 | file | ahhhhhhhhhh lurgidob! |
| 01:25.10 | lurgidob | scanline: you're going to mount /navi in .1 minutes, right? |
| 01:25.16 | lurgidob | since that's when the sync finishes |
| 01:25.22 | lurgidob | yay, just finished |
| 01:25.27 | scanline | er, huh? |
| 01:25.36 | file | navi... is going to work? |
| 01:25.37 | lurgyman | scanline: mount /navi! the sync just finished |
| 01:25.49 | lurgyman | file: that remains to be seen |
| 01:25.51 | lurgyman | scanline: hmm? |
| 01:26.02 | file | voltage regulator modules? |
| 01:26.15 | scanline | power is always current * voltage, but the difference between watts and "volt amps" is the way they define voltage, IIRC |
| 01:26.38 | scanline | normally for AC voltage you use RMS |
| 01:26.54 | lurgyman | bah |
| 01:26.54 | lurgyman | ok |
| 01:26.55 | scanline | but I think the UPS manufacturers defined 'volt amps' to use peak voltage instead, so their rating is higher |
| 01:26.57 | lurgyman | but mount /navi! |
| 01:27.19 | scanline | so p=iv always, but the issue is how you define a constant v for that measurement when v is actually changing |
| 01:27.25 | scanline | mmmmkay |
| 01:27.35 | scanline | lemme save some stuff in case it crashes :P |
| 01:27.42 | lurgyman | k |
| 01:29.36 | scanline | copying... |
| 01:29.42 | lurgyman | :) |
| 01:30.04 | CIA-5 | 03brandon * r2070 10mice/rebuild/applets/submit/question.java: Ok, now that this is fully documented, I suppose I'll commit and go to class fairly soon. |
