(15:23:36) mjl-: anothy_x: sheevaplug
(15:23:51) mjl-: i posted about it to the inferno mailing list :)
(15:23:55) mjl-: it has an arm processor

(16:21:13) mjl-: anothy_x: http://article.gmane.org/gmane.os.inferno.general/4574
(16:23:14) anothy_x: i had seen that, just had forgotten the association with your irc nick.

(18:08:27) uriel: mjl-: you might want to mention the inferno port here: http://en.wikipedia.org/wiki/SheevaPlug
(18:08:49) mjl-: good point, will do
(18:09:02) mjl-: btw, usb2 is also good for when i will get to running inferno on my x40
(18:09:28) mjl-: which is as soon as i get that intel video driver to work (which surely won't happen before i spent time on it...)
(18:15:41) uriel: mjl-: inferno on the x40, *nice*
(18:16:46) mjl-: yeah, and hopefully the ac97 driver works on the controller in there too... and its gigabit ethernet already works
(18:17:11) mjl-: then the usb2 will make it quite complete :)
(18:18:51) maht: :> what electricty supply do you have. I saw the spec and thought it didn't work on 220v/50Hz
(18:19:18) mjl-: for the x40?
(18:19:34) mjl-: dc 16v 4.5a
(18:22:46) mjl-: the input can be 110-220v 60hz.  but i bet we're over 220v nowadays, and it still works (luckily i have 4 adapters)
(18:34:35) uriel: gigabit works? wow, really cool
(18:34:40) maht: i thoguth we dropped to 220 to fit in with europe
(18:35:49) mjl-: hmm, i thought we were moving from 220 slowly to 240 (not sure why though)
(18:45:08) mennis left the room (quit: Client Quit).
(18:45:17) uriel: maht: when will you drop the stupid plugs you use?
(18:45:23) mennis [n=mennis@adsl-068-016-104-079.sip.asm.bellsouth.net] entered the room.
(18:45:35) uriel: had to spend I can't remembe rhow fucking much when I visited the UK to be able to get electricity into my laptop
(18:45:46) uriel: (to buy a stupid worthless adaptor)
(18:53:33) stu9: you can plug a euro plug into a uk socket.
(18:54:01) stu9: you just need to stick something, a screwdriver maybe, into the earth (top) hole, that opens the gates on the bottom two.
(18:54:07) stu9: (earth pin is longer)
(18:54:12) stu9: it's a safety feature.
(18:56:25) ***stu9 wishes uk sockets ruled the world.
(18:56:38) stu9: they're also the only ones I know of that don't come lose if you sneeze.
(18:57:27) npe left the room (quit: ).
(18:57:29) mjl-: i think all power sockets are quite big... couldn't they just be a bit smaller?
(18:57:44) mjl-: and the EU ones (with ground) seem to be pretty solid
(18:58:20) mjl-: anyway, if there was a plan to convert the whole world to one standard, i'll probably be fine with it and replace every outlet
(18:58:44) mjl-: assuming the new plug wouldn't be horribly bad
(18:59:33) stu9: yeah.
(19:00:09) uriel: mjl-: amen
(19:00:22) stu9: I think I've only used the european and north american plugs without any ground.
(19:01:19) uriel: also I'm not electrical expert, but I heard it would be a good idea to have DC current plugs, and avoid the stupid mess of power-briks every stupid device needs
(19:03:43) stu9: or keep the AC outlets (for whatever their advantage is, long distance transmission I think), and then just have one big brick with alot of DC outs for all the devices.
(19:03:59) stu9: some newer datacentres do this.
(19:07:37) anothy_x: that's the most efficent way to do it.
(19:07:45) anothy_x: good luck making the mass conversion, though.
(19:09:04) andguent: you could still solder some of the dc devices together to use the same brick
(19:09:07) ***andguent ducks and runs
(19:09:35) maht: uk plugs rule, as a seasoned traveller you should know the best thing to do is carry a 4way strip with your native sockets and cut the plug off and buy one locally when y ou arrive
(19:11:01) maht: though I'm guilty : remember at iwp when I had to cut the ac cable with a knife and tape it to the pins of my uk plug, that was fun
(19:11:50) andguent: hopefully there will be wireless supply somewhen :D
(19:14:47) stu9: anothy, probably more likely than getting rid of x86 and usb, mainstream use of plan 9, everyone switching to dvorak, and eliminating daylight savings.
(19:17:16) maht: http://www.flickr.com/photos/maht/319917302/in/set-72157594381075386/
(19:41:13) andguent: stupid question: how do i mount sources in inferno? 
(19:41:20) ***andguent is obviously pretty dumb these days
(19:41:24) npe [n=npe@94-224-251-223.access.telenet.be] entered the room.
(19:43:56) mjl-: mount -9 net!sources.cs.bell-labs.com!9fs /n/sources
(19:48:45) andguent: something about the "net!" thing
(19:48:51) andguent: it's not tcp, is it?
(19:48:57) mjl-: it can be
(19:49:11) mjl-: does it say /net/net doesn't exist?  if so, you need to start ndb/cs
(19:50:23) andguent: hm yeah. he complaints about "auth protocol not finished" though
(19:51:06) mjl-: do you have factotum running?
(19:51:09) mjl-: and auth/feedkey?
(19:51:17) mjl-: auth/factotum
(19:51:17) mjl-: auth/feedkey
(19:51:21) mjl-: is what i have in my lib/wmsetup
(19:51:45) andguent: do i need factotum running for connecting to sources
(19:51:46) andguent: ?
(19:52:00) andguent: hm ah bummer...too much win32 and opengl shit in the last months :-/
(19:52:06) mjl-: oh, i was assuming for use with contrib account
(19:52:14) andguent: no just read access
(19:52:27) mjl-: hmm, i haven't tried using it as such
(19:52:37) mjl-: it probably can be done, i'm not sure how though
(19:53:47) mjl-: ok
(19:53:49) mjl-: it's just
(19:53:56) mjl-: mount -A net!sources.cs.bell-labs.com!9fs /n/sources
(19:56:13) maht: re: dc power: what rails are you going to have, your computer takes +12v -12v +5v -5v maybe +3.3v -3.3v
(19:56:43) maht: your laptop will be one of 18v, 15v, 12v
(19:56:59) andguent: mjl-: yeah thats what i figured. thanks
(19:57:22) anothy_x: converting (especially downconverting) is a lot more efficient than ac/dc conversion.
(19:59:15) ***maht thinks mournfully about power over ethernet, could have been so good
(20:00:16) maht: though you can get PoE bits for your own setup
(20:00:58) ***mennis discovers iostats and is quite pleased.
(20:02:19) uriel: iostats is fucking awesome
(20:02:31) uriel: one of the coolest comands ever

(22:18:20) sea-gull [i=seagull@server1.bshellz.net] entered the room.
(22:26:25) mjl-: i just ran inferno source through the clang statical analyzer (from llvm)
(22:26:28) mjl-: it finds lost of things
(22:26:42) mjl-: but most don't seem to be bugs at first glance
(22:26:49) mjl-: but they need quite some investigation
(22:26:58) mjl-: so... something for a later time
(22:46:40) mjl-: blegh, many errors due to it not recognizing sysfatal(), error(), etc. as not continuing execution
(23:02:31) sqweek: annoying
(23:14:20) vsrinivas: mjl-: can you annotate them as noreturn?
(23:15:01) vsrinivas: mjl-: could you post the output from clang?
(23:15:38) mjl-: ah, perhaps i've used the programs wrongly
(23:16:08) mjl-: i've replaced cc with ccc-analyzer, and ran "scan-build mk install"
(23:16:32) mjl-: i should probably read the docs in more detail and try again
(23:19:25) mjl-: ok, just the "scan-build mk install" (as i am told to use by the openbsd port's README of llvm) doesn't actually seem to run anything clang analyzer related
(23:20:58) mjl-: hmm, ccc-analyzer --help returns gcc information...
(23:21:10) mjl-: options look different though.  quite strange
(23:23:18) mjl-: well, ccc-analyzer seemed to be the right program to use as cc
(23:25:13) mjl-: it seems to be analyzing per c file (with .h's included).  i guess i have to find the option to make it perform analysis only after the linking stage, where it knows that that now-resolved error() symbol doesn't return
(23:27:00) mjl-: (though i'm not sure if clang does more than just parsing and building the syntax tree)
(23:27:06) mjl-: and sorry for my mumbling...
