[8:25] <DaQatz> Morn'
[8:30] <vgrade> Pibot died on netsplit
[8:36] <DaQatz> Ah
[8:36] <DaQatz> Well the system was off when I got home
[8:36] <vgrade> ah ok, I thought it was related to the split, sry
[8:37] <DaQatz> May have been
[8:37] <DaQatz> Power could well have blinked long after
[8:37] <DaQatz> After all
[8:37] <DaQatz> I wasn't here too see it.
[8:45] <whyz> what does pibot do besides serving with US weather?

[10:51] <ahven> a buildfarm of raspi-B's would be nice :)
[11:00] <Thorn_> and slow probably
[11:01] <ahven> well, faster than one raspi :P
[11:03] <Thorn_> need an ARM boinc client for distributed code compiling :p
[11:03] <Thorn_> that would be pretty nutty

[11:04] <ahven> :)
[11:07] <ahven> I was thinking in the lines of distcc and ccache over nfs
[11:11] <ahven> the whole idea of distcc over boinc sounds interesting
[11:12] <ahven> haven't found any mention of similar thing on the first two pages of google
[11:12] <ahven> but distcc is bad on slow lines, sadly not worth it
[11:17] <Thorn_> network them over your own gpio interface rather than eth!

[16:09] <PiBot> ukscone| no i am british we are used to summer just being the third wednesday in august
[16:09] <ukscone> morning all
[16:10] <atts> morning
[16:11] <NIN101> hi
[16:16] <ukscone> need the name of a freeware program that does speech to text from a video -- any ideas?
[16:19] <ahven> ukscone: http://www.voxforge.org/home ?
[16:19] <ahven> just googled
[16:21] <ukscone> i've been googling for days and so far not found anything suitable -- i'll take a look at that link
[16:26] <ukscone> ahven: nope that won't do it i don't think -- it's remote transcription and not suitable for the task -- kid has a video of a role play he did in class and needs to do a transcription of it so he can than make notes on what he did and why he did it --
[16:29] <ahven> seems like some manual labor is in order? :P
[16:32] <ukscone> yup unfortunatly it'll be me doing the manual labour
[16:33] <ukscone> as he has to finish off his paper that is due thursday
[16:34] <ahven> http://cmusphinx.sourceforge.net/ one more
[16:49] * nemo (nemo@c-68-50-78-21.hsd1.md.comcast.net) has joined #raspberrypi
[16:49] <nemo> So. I was reading: http://www.raspberrypi.org/?page_id=43&mingleforumaction=viewtopic&t=656.2#postid-9201 since it was on your front page
[16:49] <nemo> and if "kme" hangs out here, I'd just like to mention that until my workplace got me a notebook, my gentoo laptop at home had only 96MiB of ram
[16:49] <ukscone> looks like i'll have to do it manually to start with thn if it looks like he'll have to do it more often i'll either write something or make sure i am not around when he need sot do it
[16:49] <nemo> it ran Seamonkey, XFCE4, sshd and nfs without any problems
[16:50] <nemo> 256MiB is a ludicrously generous amount of memory in comparison
[16:50] <nemo> admittedly that was on an x86 machine, so code size might not be strictly comparable, but still
[16:55] <friggle> as someone with an alpha board, I think 256MiB is plenty to create a compelling experience for children
[16:55] <ahven> my youth was with dos console prompt and games, windows 3.11 was a dull thing :P
[16:55] <friggle> I look forward to when 'kme' realises the supposedly insufficient 256mb is shared with the graphics card
[16:55] <friggle> well, GPU. You know what I mean
[16:56] <friggle> the Psion 5MX ran Debian :)
[16:56] <ukscone> :)
[16:57] <ahven> is there any more variables to the minimum memory consumtion formula? like 1680x1050x16bits=28.2Mbit memory
[16:58] <ahven> hmm, mixing pixels with bits, is that allowed in the first place? :)
[16:58] <ahven> consumption*
[17:06] * leighbb (~user@ Quit (Quit: Leaving.)
[17:23] <traeak> hmm
[18:42] * ChrisLenz (~ChrisLenz@c-71-194-107-12.hsd1.il.comcast.net) Quit (Ping timeout: 248 seconds)

[19:07] <traeak> sharing 256MB with graphics card...at 1080p thats 8MB just for a 32 bit frame buffer
[19:08] * ukscone (~Russell@cpe-68-173-234-162.nyc.res.rr.com) has left #raspberrypi
[19:09] <traeak> throw in backing store for windows
[19:09] <traeak> double buffering
[19:09] <traeak> that blows up pretty quick
[19:11] <traeak> btw, do we have information on what 2d framebuffer operations are supported ? any alpha blending ?
[19:15] * ukscone (~Russell@cpe-68-173-234-162.nyc.res.rr.com) has joined #raspberrypi
[19:15] <PiBot> ukscone| hand over the twiglets
[19:24] <nemo> traeak: aye, I can attest from trying to get Hedgewars to work on iphone, that you definitely notice that shared memory pretty fasy :)
[19:26] <nemo> add a few large textures and, boom, there's a quarter of your memory gone, or more
[19:27] <nemo> we had to add a "blurry" mode where we scaled up textures frome ones a quarter the size :)
[19:27] <traeak> not surprised
[19:27] <traeak> 128MB will make that even worse
[19:27] <traeak> the answer is: don't run things in 1080p mode :-p
[19:27] <nemo> heh. this isn't even about 1080p
[19:28] <traeak> understood
[19:28] <nemo> but I guess if we were wanting to save mem. but, eh, that's not what I want a raspberrypi for anyway
[19:29] <traeak> not for a thin client?
[19:29] <nemo> not for gaming :)
[19:29] <nemo> not even Hedgewars.
[19:29] <nemo> that's what my Pandora was supposed to be for :(
[19:30] <traeak> well, considering this thing should have more horsepower and ram than a Wii this should be doable
[19:30] <traeak> but definitely will require tweaking of some sort
[19:30] <nemo> traeak: oh. 256MiB is totally doable. specs are comparable to iphone and we have it working on there no problem.
[19:30] <nemo> apart from possibly needing the rqBlurryLand as noted
[19:31] <traeak> nemo: gotcha.
[19:31] <Thorn_> pussies, get it in 256KiB and stop whining, look at the demoscene for "how"
[19:31] <traeak> heh, android at 256MB would be fun
[19:31] <traeak> "demoscene" ?
[19:31] <nemo> Thorn_: heh. some things are more amenable to low memory than others
[19:32] <nemo> the only opimisation we could make to save memory would be packing the pixel array w/ RLE
[19:32] <traeak> going 16bit is one way
[19:32] <traeak> sadly pixel information is a hog you can't get away from
[19:33] <traeak> dealing with 250 megapixel cameras doing complex geometry
[19:33] <nemo> traeak: hm. interesting idea, although it complicates a lot of the internal manipulation of the pixel array, just like RLE would.
[19:33] <traeak> well anyways, raster stuff sucks
[19:33] <traeak> nemo: depends on how much you could delegate to the hardware or whatever might be available through SDL.
[19:34] <nemo> traeak: welll, in a lot of places we do stuff like LandPixels[y,x]:= foo;
[19:34] <traeak> "row, col" space is much better :-p
[19:34] <nemo> or rather, stuff olike LandPixels[y,x]:= LandPixels[y,x] or AMask; or something :)
[19:34] <traeak> i'm right handed not left handed :-p
[19:34] <traeak> (just me busting on computer science folks)
[19:35] <nemo> traeak: trust me, I wish it was that way too, but can't be bothered to change it all now. blame unc0rr.
[19:35] <nemo> "in soviet russia"
[19:35] <traeak> we use an explicit 3. * pi /2. rotation transformation to deal with keeping screen space and normal space separate...but again, it's our type of application
[19:38] <traeak> heh oh well
[19:39] <Thorn_> i was always a fan of the 3. 2^32sqrt(x) / log(10)ln(5)/2 matrix transformation personally...
[19:44] <traeak> Thorn_: keeps sanity with keeping transformation spaces explicitly separate
