[0:00] <shiftplusone> So, either use a different device, hdmi out or a usb soundcard (which may or may not work, I don't know).
[0:00] <shirish> alexhairyman: it doesn't have the MD5sum but the SHA1sum and that also of the .zip file.
[0:01] <pksato> omxplayer dont output audio to alsa devices.
[0:01] <shiftplusone> What does it output to?
[0:02] <pksato> direct to pwm channels or hdmi
[0:02] <shiftplusone> hm
[0:03] <shiftplusone> Didn't know that, thanks.
[0:03] <pksato> Neither I.
[0:03] <shirish> alexhairyman: and they match exactly with the .zip file I have from which I have extracted the .img file.
[0:04] <pksato> I test another day, unload bcm alsa modules, and run omxplayer, and sound came.
[0:04] <shirish> alexhairyman: when you make BS=1M from BS=4M you are making it slow or fast for the transfer ?
[0:04] * jimerickson (~jimericks@pdpc/supporter/active/jimerickson) has joined #raspberrypi
[0:05] <dr_willis> you may not notice any gains wth higher bs values
[0:05] <pksato> and, plug a usb sound card, a oxmplayer out from RPi jack, not usb.
[0:06] <shirish> dr_willis: thanx for sharing that. Another query, do bs values have any role to play in the fragmentation of the disk or not ?

[0:10] * brady2600 (~ludwig@71-208-46-232.hlrn.qwest.net) has joined #raspberrypi
[0:11] <shiftplusone> pksato, in general, are usb soundcards problematic on the pi?
[0:12] <shirish> alexhairyman: now it's stuck at 640 MB, is there a way to clean the SDHC card and see if the card is ok or not ?
[0:14] * innaway_ (~innaway@anon-149-211.vpn.ipredator.se) has joined #raspberrypi

[0:20] <pronto> http://raspberry.bagels.xxx/ yay for silly DNS things xD
[0:20] <dr_willis> shirish: i wouldent think so
[0:21] <shirish> dr_willis: thanx.
[0:21] <shirish> Query to everyone, is there a way to clean the SDHC card and see if the card is ok or not ?
[0:21] <dr_willis> use dd from /dev/zero to zero out the card
[0:22] <dr_willis> ive dd'd to sd cards dozens+ times and never messed one up
[0:23] <shirish> dr_willis: newbie here, could you kinda make it easier so I know what I need to do .
[0:23] * debenham (~cjd@ Quit (Quit: Leaving.)
[0:23] <Gordio> "Mem: 438..." T_T
[0:23] <dr_willis> the device is /dev/zero you use it for your if= instead of a file
[0:23] * debenham (~cjd@ has joined #raspberrypi
[0:24] <Gordio> "Mem: 184" T_T
[0:24] <dr_willis> dd if=/dev/zero of=/dev/sdX bs=whatever
[0:24] <Gordio> And I compile CPP.
[0:25] <Gordio> CPP sucks!
[0:26] <alexhairyman> shirish dr_willis, cat /dev/zero would work to
[0:26] <shirish> alexhairyman: thanx.
[0:26] <alexhairyman> and you are doing sdb right?
[0:27] <shirish> alexhairyman: I was trying there but now it seems it mounted it /dev/sdd
[0:27] <shirish> alexhairyman: guess 'dmesg' is the only tool to know what is mounted where and how.
[0:30] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 252 seconds)
[0:30] <alexhairyman> shirish, mount is the tool to find out where things are mounted
[0:30] <alexhairyman> just run 'mount'
[0:30] * viric (~viric@unaffiliated/viric) has left #raspberrypi
[0:31] <alexhairyman> and it will print every /dev/sdX device, and all files, and where they're mounted in the filesystem
[0:31] <alexhairyman> lsblk probes for devices, and is an invaluable too
[0:31] <alexhairyman> *tool
[0:31] <dr_willis> the blkid command may show where its at also..
[0:32] <Gordio> lsblk, blkid
[0:32] * BaroMeter (~BaroMeter@h158n11-sde-d2.ias.bredband.telia.com) has joined #raspberrypi
[0:32] * debenham (~cjd@ Quit (Remote host closed the connection)
[0:33] <dr_willis> after you dd it with /dev/zero you dont mount it. :) since it has no filesystem on it
[0:33] <Gordio> no filesystem and no partition table :D
[0:34] <dr_willis> Theres ways i recall to have a FS without a partion table.. but i forget how or why... ;)
[0:35] * innaway_ (~innaway@c-68-33-34-221.hsd1.dc.comcast.net) has joined #raspberrypi
[0:35] * aphadke (~Adium@c-71-198-5-34.hsd1.ca.comcast.net) has joined #raspberrypi
[0:35] <Gordio> Need only FS? mkfs.vfat /dev/sdd
[0:35] * innaway__ (~innaway@anon-147-199.vpn.ipredator.se) has joined #raspberrypi
[0:35] <dr_willis> I cant rember why i saw it used. Was on some artical i recall..
[0:35] <dr_willis> guess an ISO/DVD does the same thing.. you got a sr0 drive but not a sr0p1 ;) partition
[0:36] <alexhairyman> It does have a filesystem on it though
[0:36] <alexhairyman> fdisk -lu <image name>
[0:37] <alexhairyman> fdisk -lu blah-wheezy-blah.img
[0:37] * innaway (~innaway@anon-149-211.vpn.ipredator.se) Quit (Ping timeout: 244 seconds)
[0:37] * innaway__ is now known as innaway
[0:37] <alexhairyman> and you'll get the offsets that can allow you to mount the patitions inside the file too
[0:37] * Kane (~Kane@ Quit (Quit: Night all o/)

[0:39] * innaway_ (~innaway@c-68-33-34-221.hsd1.dc.comcast.net) Quit (Ping timeout: 256 seconds)
[0:40] <Gordio> alexhairyman, hm. I see iffsets with "file" :D
[0:40] <Gordio> offset's
[0:40] * sphenxes (~sphenxes@91-119-228-178.dynamic.xdsl-line.inode.at) Quit (Read error: Connection reset by peer)
[0:40] <alexhairyman> ?
[0:41] <alexhairyman> the partition inside the file is offset by it's starting point * 512 (usual sector size)
[0:41] * tinti (~tinti@pdpc/supporter/student/tinti) Quit (Quit: Leaving)
[0:41] * egrouse (~newb@unaffiliated/egrouse) has joined #raspberrypi
[0:42] <shirish> alexhairyman: dd doesn't give output, hence using now 'dcfldd if=/dev/zero of=/dev/sdd statusinterval=10' and it's looking good.
[0:42] * netprince (~chatzilla@ip68-106-85-10.rn.hr.cox.net) has joined #raspberrypi
[0:42] * dreamon (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[0:42] <alexhairyman> shirish, no, dd doesn't give output, pv does
[0:42] <shirish> alexhairyman: ah... now I see what was taking so much time, it's an 8 GB device so it's gonna take a long time.
[0:43] <alexhairyman> shirish it shouldn't take long
[0:43] <alexhairyman> maybe 10-15 mintues
[0:43] <alexhairyman> at most
[0:43] * Naphatul (2ed900fa@gateway/web/freenode/ip. Quit (Quit: Page closed)
[0:44] * egrouse (~newb@unaffiliated/egrouse) Quit (Client Quit)
[0:44] <shirish> alexhairyman: would this work ? sudo bash -c "pv dclfdd if=/dev/zero of=/dev/sdb bs=1M"
[0:45] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) Quit (Quit: Leaving)
[0:45] <shirish> alexhairyman: would this work ? sudo bash -c "pv dclfdd if=/dev/zero | of=/dev/sdb bs=1M"
[0:45] <alexhairyman> no no, pv just outputs the file, and you don't /really/ need to zero out the drive
[0:46] <alexhairyman> 93.8MiB 0:00:18 [3.11MiB/s] [======> ] 4% ETA 0:05:44
[0:46] * nardev (~nardev@ has joined #raspberrypi
[0:46] <alexhairyman> that's what pv looks like
[0:46] <shirish> alexhairyman: I'm doing the zero out so at least I know the SDHC is clean and then start again, I know it will take a bit longer but better safe than sorry.
[0:49] * debenham (~cjd@ has joined #raspberrypi
[0:50] <shiftplusone> .... it... doesn't work that way. Safer in what way?
[0:51] <shiftplusone> It's not like an audio cassette where you had to record silence onto them before re-recording to get clean audio.
[0:52] * BlueDreams (~matt@mf52736d0.tmodns.net) Quit (Ping timeout: 276 seconds)
[0:54] <shirish> shiftplusone: oh... ok. I thought it was like that.

[0:56] <alexhairyman> shirish, here is how I /just/ (like 5 minutes ago flashed my drive

[0:57] <shiftplusone> I haven't been following the convo, but I think this might be relevant. Using pv isn't going to give you accurate information.
[0:57] <shirish> alexhairyman: nice. Doing the same thing.
[0:57] <alexhairyman> shiftplusone, how so?
[0:57] <shirish> shiftplusone: I just wanted a progress bar to know if something is happening or not.
[0:58] <alexhairyman> that's exactly why I did it too shirish, I had problems flashing too :D
[0:58] * fayimora (~fayimora@2a01:388:201:3720:e0b6:d186:5d3:9ed) has joined #raspberrypi
[0:58] <shiftplusone> I think it reads a lot quickly into memory so you can get something like 40% done straight away and then continues slowly from there as it actually writes from memory to sd. Not a big deal, but might be relevant.
[0:58] <shirish> alexhairyman: :D
[0:58] <alexhairyman> shiftplusone, it does do that, but only for a small portion of the file
[0:59] <shirish> shiftplusone: not at my end. It might be because you have 8 Gigs of memory, but at my end not like that.
[0:59] <shiftplusone> Ah ok, fair enough.
[0:59] <alexhairyman> shirish, and then we need to resize the partition so you get the full size of your sd card OK?
[0:59] <shirish> alexhairyman: know about that. using raspi-config
[0:59] <alexhairyman> Is that a script that does it for you?
[1:00] <shirish> alexhairyman: you are using the debian wheezy image or the arch one ?
[1:00] <shiftplusone> It's the config script that runs when you first boot up. Resizing is one of the options it gives, yes.
[1:00] <alexhairyman> shirish arch all the way man!
[1:00] <alexhairyman> os[alexhairyman@alexhairypc, Linux 3.6.11-1-ARCH i686]
[1:00] <shirish> alexhairyman: debian here m8.
[1:00] <alexhairyman> ARCH, woohoo!
[1:00] <alexhairyman> shirish debian is pretty nice
[1:00] <Torikun> Arch ft!
[1:00] <Torikun> *ftw!
[1:00] <shiftplusone> raspi-config is a raspbian thing though, so you won't have it on arch or whatever else.
[1:00] * bacilla is now known as Velkam
[1:01] <alexhairyman> shiftplusone, I just use fdisk and resizee2fs
[1:01] <shirish> alexhairyman: anyways, there is a script called raspi-config. See http://raspberrypi.stackexchange.com/questions/1322/where-is-the-script-for-raspi-config-stored-in-the-fs-on-raspbian
[1:01] <alexhairyman> which is what I believe the script does too :)
[1:01] <shiftplusone> yup, that's exactly what the script does anyway
[1:01] <alexhairyman> lol
[1:02] <Kisume> Arch is beautiful.
[1:02] * Kisume (~Kisume@unaffiliated/kisume) Quit (Quit: Sleepytime.)
[1:02] <alexhairyman> arch is great, but I still have a place for debian/ubuntu in my heart
[1:02] <Gordio> Arch good, not beatiful.
[1:02] <alexhairyman> very strong
[1:02] <shirish> alexhairyman: finally done with that part.
[1:02] <Gordio> Gentoo - beautiful!

[1:34] <shirish> hi all, stupid question - are there any cables similar looking to HDMI cable but bigger ?

[1:36] <shirish> Caleb: I got this one http://www.bizlinktech.com/pix/future_dp_conn_002.jpg and it doesn't fit with the HDMI connector on the raspberry pi.
[1:36] <Caleb> ill look
[1:36] * Sendoushi (~Musok@cm2-84-91-84-50.netvisao.pt) Quit (Remote host closed the connection)
[1:36] <shirish> Caleb: thanx.
[1:36] <maden> hi. I have a 1TB Western Digital HDD that is internally powered (only 1 usb plug on the drive). when I plug the drive in my RPi, it tries to spin the drive but it times out after 180 seconds, which I believe is because it cannot draw enough power out of the board. I was thinking if anyone found a workaround this to power the drive externally and still provide access to the disk?
[1:36] <Caleb> shirish: looks like one end is cornered
[1:37] * bacilla (~karolis@unaffiliated/velkam) has joined #raspberrypi
[1:37] <shirish> Caleb: exactly, this doesn't look to be a standard HDMI cable, something else.
[1:37] <Caleb> maden: use a powered hub for the drive
[1:37] <Caleb> shirish: looks like something for a computer
[1:37] <Caleb> not even hdmi
[1:37] * Oddj0b (~oddj0b@ Quit (Remote host closed the connection)
[1:37] <maden> Caleb: some kind of power bar but for USBs that is then plugged into the wall socket?
[1:37] <Caleb> yep
[1:37] <shirish> Caleb: it is for a computer.
[1:38] <maden> like this? http://t3.gstatic.com/images?q=tbn:ANd9GcRUDxSqdfrG-PoRDBVCmxBsDUvCyZeda1sUj3BdJJOJVyVOVpmz
[1:38] <Caleb> shirish: was it shown as a hdmi cable?
[1:38] <Caleb> maden: yep looks good
[1:38] <maden> thanks Caleb
[1:38] <Caleb> no problem
[1:39] <shirish> Caleb: it's a friend's cable I bought over. On one hand it has a display port on the other the port I showed you.
[1:39] <Caleb> no idea
[1:40] <shirish> Caleb: seems like sort of displayport cable.
[1:40] <Caleb> for mac?

[1:40] <Caleb> looks like thats what it is
[1:41] <Caleb> displayport that is

[1:41] <shirish> Caleb: yup, just saw the wikipedia page - https://en.wikipedia.org/wiki/Displayport
[1:42] <Caleb> maden: i might get me a powered hub
[1:43] <Caleb> so i can use it for my pi hooked to my tv
[1:43] <maden> yeah I will definitely get one, I'm quite disapointed this drive isn't plug and play...
[1:43] * prg3 (~prg3@chatter.majestik.org) Quit (Ping timeout: 255 seconds)
[1:43] <maden> I'm reading on the wiki about supported hubs but I dont understand what "backfeeding is"
[1:43] <maden> "backfeeding" is *
[1:43] <maden> not sure if it's good or bad.
[1:44] <Caleb> maden: its pulling more power that the pi puts out
[1:44] <maden> so it's bad
[1:44] * prg3 (~prg3@chatter.majestik.org) has joined #raspberrypi
[1:44] <Caleb> backfeeding could mean that the hub might be pushing too much power
[1:46] <maden> im trying to find how much power it needs...
[1:46] <maden> my drive
[1:47] <Caleb> 5V probablly
[1:47] * aphadke (~Adium@c-71-198-5-34.hsd1.ca.comcast.net) Quit (Quit: Leaving.)
[1:47] <maden> i cant find the info
[1:48] <maden> im realy not sure which one i should get
[1:49] <Caleb> well find out how much power a usb port puts out
[1:49] * debenham (~cjd@ has joined #raspberrypi
[1:49] <Caleb> and it will tell you
[1:50] <maden> what do you mean?
[1:50] <Caleb> well if the drive doesnt have external power then its just running off the power a usb port on a computer puts out
[1:50] <maden> oh, yeah
[1:50] <maden> its 5V i just found it
[1:50] <Caleb> see
[1:50] <maden> so I need to find a hub that can provide this much voltage
[1:51] <Caleb> any hub would work
[1:51] <Caleb> because it will only pull the voltage it needs
[1:51] <maden> do you know any that are worth looking into?
[1:51] <Caleb> check newegg and tigredirect
[1:51] <maden> belkin looks like it's a popular brand
[1:51] <Caleb> look at user ratngs
[1:53] <maden> so just to be sure I understand this
[1:53] * bacilla (~karolis@unaffiliated/velkam) Quit (Ping timeout: 252 seconds)
[1:53] <maden> you plug the hub in the wall socket, it gets power. then you plug your devices into your hub, and then connect a single usb cord from the plug TO the pi?
[1:53] <maden> and it will see all the devices plugged into the hub?
[1:53] <ParkerR> Yes
[1:54] <maden> that sounds like magic
[1:54] <ParkerR> How so?
[1:54] <maden> i dont know much about hardware but... if it's only one drive being used for the pi... how does addressing work?
[1:54] <ParkerR> That sounds like a typical setup
[1:54] <maden> one plug*
[1:55] <ParkerR> By one plug do you mean the hub providing the power throught he USB port?
[1:55] <maden> yeah
[1:55] <maden> well, no
[1:55] * manitou (~manitou@unaffiliated/manitou) Quit (Ping timeout: 256 seconds)
[1:55] <maden> say you have the pi, and a hub which has one usb drive and a webcam
[1:55] <maden> how does the pi communicate with the correct drive if its only one cord relaying both devices?
[1:55] <pksato> one usb port, many devices.
[1:55] <ParkerR> maden, Addressig
[1:55] <ParkerR> Just like on any computer
[1:55] <maden> yeah thats what I don't get
[1:56] <pksato> maden: no only pi, any computer do it.
[1:56] <ParkerR> USB bus
[1:56] <maden> yes I figured... i just dont see how that works
[1:56] <ParkerR> Haha "Universal serial bus us"
[1:56] <maden> oh well
[1:56] <ParkerR> *bus bus
[1:56] <maden> recursive!
[1:56] <maden> ok well, I will look for a hub that fits my needs
[1:57] <maden> any of you guys have bought one and want to recommand it?
[1:57] <Caleb> maden: well using the same hub you can power the pi and the devices plugged into the pi
[1:57] <maden> hey... thats true

[2:08] <prontosaurus> having a hard time getting wifi working. I've got an rtl8192cu adapter that I had working with a beaglebone before. followed the ladyada instructions (http://learn.adafruit.com/adafruits-raspberry-pi-lesson-3-network-setup/setting-up-wifi-with-occidentalis though I'm running Raspbian). two things: 1. the adapter doesn't always come up after reboot. it reliably will if I plug it in after boot though, or unplug & replug. using a 1A
[2:08] <maden> why is it so hard to find info about drives online...
[2:08] <prontosaurus> so I don't think that's it. dmesg makes it look like things are fine: http://pastie.org/5872849
[2:08] <maden> i dont care about it's height ... i want the voltage!
[2:09] <prontosaurus> 2. when I do that plugging, wlan0 shows up as an interface, but doesn't associate with the SSID. I've installed wicd and wicd-curses but they don't seem to be able to find *any* wireless networks. Tried a different adapter (I have a couple of identical ones hanging around), no dice.
[2:09] <prontosaurus> any ideas? linux wifi drives me absolutely insane, I wasted months on this with the BeagleBone (which admittedly used a nontraditional connection manager with nonexistent documentation, so I'm at least optimistic that this will go better)

[4:38] <[Ex0r]> I need to make sure it mounts it automatically, and to the same location each time because I need to setup a python script that is ran every 4 minutes to run a simple read on the drive (it goes into sleep mode after 5 minutes)
[4:39] <tdy> what's wrong with sleeping during inactivity?
[4:39] <[Ex0r]> The drive doesn't turn back on by itself, you have to reboot
[4:39] <sraue> and... not possible to change the time for sleeping?
[4:39] <[Ex0r]> nope
[4:39] <tdy> wow.. glad i don't have one of those
[4:40] <[Ex0r]> can't disable or change the time
[4:40] <[Ex0r]> so I have to make a script to do a simple /read/ on it every 4 minutes so it doesn't go idle
[4:41] <shiftplusone> can't dd if=/dev/sda of=/dev/null count=1 ?
[4:41] <[Ex0r]> lol I have no idea what that means

[4:42] <shiftplusone> A way to read from the disc and discard the data read.
[4:42] <shiftplusone> Without having to mount it
[4:42] <[Ex0r]> wouldn't that use alot of resources doing /dev/sda ? (Reading the entire disk) ?
[4:42] <shiftplusone> count=1
[4:42] <[Ex0r]> ah, gotcha, didn't see that part
[4:43] <shiftplusone> might want to set bs to something as well
[4:43] <[Ex0r]> if it's already mounted, couldn't I use dd if=/media/usbHD of=/dev/null count=1 ?

[4:44] <[Ex0r]> ?
[4:44] <shiftplusone> of=
[4:45] <[Ex0r]> yep, typo, my bad
[4:45] <[Ex0r]> is there a difference between sda1 and sda ? I have both listed
[4:45] <shiftplusone> sda is the whole disc, sdX refers to partitions
[4:45] <[Ex0r]> gotcha
[4:45] <[Ex0r]> so I guess i'll just make the cron job to do that than
[4:46] <shiftplusone> I am not sure if it will even work for your purpose, just throwing the idea out there
[4:46] <[Ex0r]> All it needs to do is access the drive
[4:46] <shiftplusone> though I think there's probably a way to prevent it from going to sleep with hdparam or something like that.
[4:46] <pksato> sleep mode?
[4:46] <pksato> a hard disk?
[4:46] <[Ex0r]> its something in the sata to usb controller that does it
[4:47] <pksato> disable it. use hdparm
[4:49] <[Ex0r]> hdparm -B 255 looks like the command to do it, but as I said I don't think it's in the drive itself, it's on the controller itself
[4:49] <pksato> its a HDD function.

[4:50] <Torikun> yo
[4:51] <pksato> But. that problem if HDD enter on standby?
[4:51] <[Ex0r]> hmm, that'll stop the disk from spinning, but in the case of mine the actual drive unmounts and is no longer recognized
[4:51] <[Ex0r]> and the only way to bring it back up is to reboot the pc to re-establish the usb connection
[4:52] <[Ex0r]> the led power light on the drive even turns off, that's what's leading me to believe it's most likely the controller cutting all power to the drive after inactivity
[4:53] <pksato> never see that.
[4:53] <[Ex0r]> I think i'll just use a cron job to do what shiftplusone suggested, little overhead and it'll surely work since it's accessing the drive

[6:00] <uabn93> i didnt like scp

[6:00] <dr_willis> and why would that be?
[6:00] <Aivaras> Then sftp
[6:00] <dr_willis> its as simple to use as cp ;)
[6:00] <uabn93> what are good ftp programs?
[6:01] <dr_willis> ftp in this day and age is best avoided. ;)
[6:01] <Aivaras> I use filezilla
[6:01] <Aivaras> It also can connect to sftp
[6:01] <s5fs> filezille all the way
[6:01] <Gordio> mc better :P
[6:01] <Gordio> and curlftpfs :P
[6:01] <dr_willis> mc is too handy to ignore. ;)
[6:02] <uabn93> dr_willis: it is just that the naming schemes of my torrents get annoying. can you scp while in an ssh session?
[6:02] <dr_willis> i still havent found a definitive good guide on using it. ;) and ive been using it for years.. i dont think i know 1/2 its features
[6:02] <dr_willis> uabn93: you can scp from any shell.
[6:02] * rawsted (~tom@unaffiliated/rawsted) Quit (Remote host closed the connection)
[6:02] <Aivaras> uabn93, yes
[6:02] <dr_willis> scp to or from a 2nd machine.
[6:02] <dr_willis> use sshfs to mount a remote ssh box..
[6:03] <dr_willis> ssh and scp,sftp and so on are so handy. ;)
[6:03] <uabn93> Aivaras: Is filezilla lightweight? I'm using my pi with a torrent and mpd daemon
[6:03] <Aivaras> well.. not really.
[6:03] <s5fs> uabn93: it is if you only run it when you need it
[6:04] <s5fs> for occasional file tranfers i just use scp, it's basically 'free' you know?
[6:05] <uabn93> i guess ill stick to scp for now.
[6:06] <Aivaras> if eht lights are blinking is that mean that pi is loaded normally?

[6:08] <Aivaras> I think it is scp ./Music user@ip:/Music
[6:08] <uabn93> let me try that

[6:10] <Opinie> Aivaras: and what's wrong with GUI?
[6:10] <uabn93> Aivaras: There is a minimal image out there. "headless image"
[6:10] <uabn93> for server use
[6:10] <Aivaras> for any not GUI use. :))
[6:11] <Opinie> does it actually matter whether it has gui or not? just don't type "startx" and you should be golden, no?
[6:11] <Aivaras> no gui - more free space :)
[6:11] <Opinie> ok
[6:11] <uabn93> Opinie: true. the minimal image is about 300MB though.
[6:12] <wakoinc> @Aivaras what did you plan on doing with the temperature data after storing it?
[6:12] <Opinie> ah, didn't realize it made that much of a difference
[6:12] <Aivaras> wakoinc, Not sure yet :D I would like it to be easy to use by any processing tool or language.
[6:14] <wakoinc> The other thing is how often do you want to log the data?
[6:14] <wakoinc> umm, mores, how often you want to log the data
[6:14] <Aivaras> like every 15 minutes
[6:14] <wakoinc> moreso'
[6:15] <wakoinc> you can just go with a flat file, each new timestamp and temperature is on a new line
[6:15] <wakoinc> and the values are separated by a comma
[6:15] <Aivaras> wakoinc, and what kind of date format do I need?
[6:15] <wakoinc> depends how accurate you want
[6:16] <wakoinc> unix time would likely be fine
[6:17] <Aivaras> but it is kind of unfriendly then you have log file isin't it?
[6:17] <uabn93> would it be wise to A) install ssh-server on the pi only and connect from other pc or B) isntall ssh-server on pi and laptop and scp from pi into laptop
[6:18] * hobo_ (~hobo@d207-6-226-184.bchsia.telus.net) has joined #raspberrypi
[6:18] <s5fs> Aivaras: nothing wrong with flat files for simple logging
[6:18] <Datalink> you can use tail to get the last few lines, grep the file to find a specific time period
[6:18] <wakoinc> Aivaras: well, the data is then easy to move later using any language.. into a database, or whatever
[6:18] <wakoinc> and with data every 15 mins, a flat file should be fine
[6:18] <Datalink> CSV is damn easy to parse into a database
[6:19] <Aivaras> would date +"%Y,%m,%d,%H,%M" 2013,01,27,05,18 be ok?
[6:19] <Aivaras> 2013,01,27,05,18,tempvalue
[6:19] <uabn93> what does this scp error mean: "syntax error near unexpected token `(' "
[6:19] <Datalink> so long as you have it recorded somewhere for later, yeah
[6:19] <Gordio> Not OK
[6:19] <Gordio> !
[6:20] <Datalink> erp?
[6:20] <Datalink> I'll shut up
[6:20] <s5fs> Aivaras: no, don't mess with the format like that. leave it in a normal date format.
[6:20] <Gordio> <DATE> <TIME> | <FLOAT_VALUE> C/F
[6:20] <wakoinc> i would just use unix time.. just keep in mind it doesn't deal with timezone
[6:20] <uabn93> i escaped it with a backslash. anyone?
[6:20] <hobo_> how often do you guys break your distro? i keep running into problems
[6:20] <Gordio> 2013-01-23 18:34:02 | 1.7 C
[6:20] <wakoinc> 1359263993,25 = unix time,temp\n
[6:20] <s5fs> uabn93: without seeing what you were trying to scp i can't say what the deal was
[6:21] <Aivaras> Gordio, it would be easy to process later?
[6:21] <Gordio> Aivaras, yup
[6:21] <wakoinc> uabn93: the pi has ssh pre-installed (i think if a newer model)
[6:21] <Gordio> but unixtime realyeasy :D
[6:22] <hobo_> ssh is on for weezy
[6:22] <hobo_> i'm having problems with the partitioning i think
[6:22] <uabn93> s5fs: " ... /home/pi/incomplete/01\ -\ No.\ 1\ in\ G\ minor\ \(orch.\ Brahms\).flac ."
[6:22] <Aivaras> Gordio, but if I open log file I won't understand what time it really was without conversation
[6:22] <[Ex0r]> okay, so now im at a loss. using raspbmc and trying to setup a user that can directly ftp into my usb hdd thats plugged in. It's mounting the hdd using fuse, but I can't get an ftp user to get access to the directory I need to dump the files into
[6:22] <Gordio> Aivaras, possible save both
[6:22] <Aivaras> Gordio, Damn you good.
[6:22] <wakoinc> Aivaras: yeah, just save three values
[6:22] <hobo_> https://dl.dropbox.com/u/3120116/20130126_211842%280%29.jpg
[6:23] <s5fs> uabn93: yeah, escaping was the right move. i usually make tarballs with simple names before copying them, but whatever works :)
[6:23] <hobo_> that's the problem i've run into
[6:23] <wakoinc> unixtime,temp,human datetime
[6:23] <Aivaras> human :DD
[6:23] <Aivaras> ok, thanks :D
[6:23] <s5fs> hobo_: well that doesn't look very good

[6:24] <Aivaras> C I think, or maybe php if I need something on web
[6:24] <wakoinc> hobo_: I would look at the powersupply
[6:24] <uabn93> s5fs: for some reason it gives me errors around the "(" even though i escaped it
[6:24] <hobo_> wakoinc: it's been working before
[6:24] <[Ex0r]> If you need PHP help I can help you
[6:24] <Aivaras> Not yet, but thanks :)
[6:24] <s5fs> hobo_: no idea, but i'd expect a reimage would fix things
[6:24] <hobo_> i probed 4.75V at the tp points
[6:25] <s5fs> uabn93: escaping goofy chars in a file can be a pain. you could try creating a 'swap' directory, then just using 'scp * user@pi:/place/to/go'

[6:26] <Aivaras> damn my pi restarted again. I need better power supply/powered USB hub
[6:26] <Gordio> Aivaras, whot you do before restart?
[6:26] <dr_willis> My znc server pi runs decently well on a minimal power supply from the powered usb hub.
[6:26] <wakoinc> hobo_: I really think you have a hardware problem
[6:26] <hobo_> why do you think that?
[6:26] <uabn93> s5fs: good idea. SSH and SCP are still new to me. never had use for it before i got a pi
[6:26] <Aivaras> Gordio, pluged usb flash drive in. :D
[6:26] <wakoinc> I've never seen software cause that kind of problem
[6:26] <Gordio> :D
[6:27] <Datalink> I'd use , as a seperator, it's more natural for CSV parsers
[6:27] <Gordio> yes need more power! :)
[6:27] <hobo_> i'm using a kindle adaptor
[6:27] <s5fs> uabn93: i'm sooo lazy man, i love scp and i keep my file names simple. if i can use wildcards i totally do. its fun!
[6:27] <Gordio> Aivaras, or if can sold capacitor =)
[6:27] <dr_willis> ive seen where plugging in a flash drive has crashed/reset my pis.. but i havent noticed it since i got them all in cases now.

[6:32] <Aivaras> wakoinc, so my unix time is different from yours or it just give +0 time?
[6:33] <wakoinc> well, its seconds since EPOC on Thu, 01 Jan 1970 00:00:00 GMT
[6:34] <wakoinc> and I believe it uses GMT to calculate, so when you want to change it into your timezone, you just add you timezone offset
[6:34] <hobo_> if i can't unmount a disk, what does that mean?
[6:34] <Aivaras> oh, since I am in GMT that won't be a problem :D
[6:35] <Aivaras> that something is using it now
[6:35] <Opinie> hobo_: that you shouldn't yank it off of your device - at least not before you can unmount it
[6:35] <wakoinc> its never a problem, just consideration
[6:36] <Aivaras> It was problem once.. :D flight and train tickets...

[6:43] <wakoinc> what kind of course are you in?

[6:43] <hobo_> why would anybody want to configure python with windows
[6:43] <Aivaras> Computer science first year.
[6:43] <Aivaras> why would anyone want something with windows. That is a question. :D
[6:43] <hobo_> well i need windows for many things, CAD amongst one of them
[6:44] <Aivaras> there is some linux cad software too.
[6:45] <hobo_> not nearly as good though
[6:45] <hobo_> there's a linux alternative to many things, but usually it's not as refined

[6:53] <wakoinc> except of windows 8 - wow that was such rubbish
[6:53] <hobo_> oh i haven't tried that still
[6:53] <hobo_> tbh, i still like xp a lot
[6:53] <Aivaras> actually I think that windows 8 is pretty good compared to 7/vista
[6:54] <Aivaras> it is faster and more stable.
[6:54] <Aivaras> and if you don't like that new interface you can always install old start thing.
[6:54] <wakoinc> I can't say really with performance or stability.. but it is unfriendly
[6:54] <Aivaras> also new BSOD is better now :D
[6:55] <KnMn> That new interface doesn't even bother me in win 8. I hit the windows key and then start typing the name of the program I want, exactly the same as i do in win 7

[7:01] <Aivaras> UK, I try to buy on ebay.
[7:01] <hobo_> in canada
[7:01] <hobo_> also ebay
[7:01] <Aivaras> then I was in Lithuania I was ordering from local retailer.
[7:02] <wakoinc> I found a retailer, but ordering here is also impossible. you need to go to a bank and transfer money into their account, wait some days, email them
[7:03] <Aivaras> don't you have online banking?
[7:03] <wakoinc> I'll just go pick it up in a week when I head to Bangkok
[7:03] <wakoinc> they don't have CC support, hah
[7:03] <Aivaras> but simple account?
[7:04] <wakoinc> umm, international money transfers are a pain
[7:04] <Aivaras> well it costs, but... you can make it.
[7:04] <wakoinc> here it is all done at banks

[8:12] <Aivaras> what is the difference between IP and MAC binding and DHCP address reservation?
[8:13] <hobo_> umm not yet
[8:13] <hobo_> the idea is that the soil modules will sensor moisture, transmit via xbee to rpi connected to network
[8:14] <hobo_> rpi will transit to another xbee connected to water valve to turn on/off sprinkler

[8:14] <wakoinc> http://www.futurlec.com/Gas_Sensors.shtml are cool
[8:14] <Eartaker> Aivaras: you can reserve an IP so that DHCP will hot hand it out. this way you can staticly assign it to something like a server. A MAC bind will tell DHCP to allways hand that IP to that host.
[8:14] <VetteNix> hobo, seems pretty intense
[8:15] <hobo_> i ordered http://www.vegetronix.com/Products/VG400/
[8:15] <VetteNix> i just wanna replace my current sprinkler timer with a pi or arduino :P
[8:15] <wakoinc> is xbee easy to interact with? where do you find the docs for each device?
[8:15] <Aivaras> Eartaker, then I setup reservation - they ask for MAC too :/

[8:21] <wakoinc> Aivaras: I think you can do it two ways
[8:21] <wakoinc> Aivaras: every device has a specific mac address, but the IP can change. So, your router can reserve an IP address for a specific device (using its mac address)
[8:22] <dcorona_irc_2020> I have installed the Atheros driver, it seems to be detected. Wpa gui scans it but not connecting
[8:22] <wakoinc> Aivaras: and then the device can also request a specific IP address at time of connect
[8:22] <Aivaras> I know that. I just don't get difference between two settings.
[8:23] <axion> or just configure client-side to use static ip. connection will be faster and always have the ip you tell it
[8:23] <Aivaras> and setup it once again then connecting not in home :)
[8:23] <Aivaras> that would be really faster
[8:24] <axion> different profiles
[8:24] <Aivaras> still
[8:24] <axion> netcfg works
[8:25] <rikkib> I tend to use static as I am always using gateways
[8:25] <axion> i use static when home or on bad wifi where dhcp will likely time out
[8:25] <rikkib> port forwarding and proxy aggregation points
[8:25] <wakoinc> static is nice for ssh and such also.. so the IP is always the same
[8:26] * jthunder (~jthunder@ has joined #raspberrypi
[8:27] <Aivaras> that is way reservation from router side is good
[8:27] <Aivaras> it does not mess up things then you are connecting not to this router
[8:27] <wakoinc> yeah
[8:28] <wakoinc> depends if you move it around a lot
[8:28] <wakoinc> it also means that you won't accidentally have two devices wanting the same IP

[8:49] <Aivaras> So you have to register user for every device?
[8:49] <dr_willis> I quit a channel on the phone - it closes them on all the pcs

[8:52] <dr_willis> the apt system makes it fairly easy to pull in the needed deps and compile a newer

[8:56] <dr_willis> One neat thing with znc. My android phone is connected as is my computer.. so when ever i get a mesage.. my phone beeps. ;) whever am at in the house i can hear it.
[8:56] <piney0> ahh, nice
[8:57] <axion> znc seems redundant
[8:57] <wakoinc> if you have one device.. it is
[8:57] <axion> i do not
[8:58] <piney0> i want znc to keep me logged in and stuff
[8:58] <axion> i use tmux on my irc client machine. and i ssh in from multiple devices/locations to the same irc instance
[8:58] <dr_willis> you can set up your friends where they can znc in. :) and have your own private network easially
[8:58] * debenham (~cjd@ has joined #raspberrypi
[8:58] <dr_willis> I tried sshing in from my phone and screen.. it was a bit more bothersom then using a native android client
[8:58] <wakoinc> axion: is that easy to work on a mobile?
[8:59] <axion> same as it is elsewhere
[8:59] <chickens> dr_willis: irssi connectbot app on android
[8:59] <dr_willis> chickens: thats one of the worst ssh clients ive used.
[8:59] <dr_willis> and its one of the better ones on the market. ;)
[8:59] <dr_willis> it has big issues.
[8:59] <chickens> really, it works fairly well for my needs
[9:00] <dr_willis> server auditor is what i use now
[9:00] <dr_willis> i dont use irssi. i used weechat.. and conenctbot dident send all the key codes properly.
[9:00] <axion> dr_willis: o/\o
[9:01] <chickens> ah, I find weechat to be combersome after being so used to irssi
[9:01] <dr_willis> im also using a bluetooth keyboard most of the time at work on my phone.
[9:01] <dr_willis> i find irssi primitve now after being used to weechat
[9:01] <axion> agreed
[9:01] <chickens> seeing that I came from bitchx, it fits me
[9:01] <axion> weechat's smart filtering alone makes it worth it
[9:02] <dr_willis> yep.
[9:02] <Gordio> axion, weeechat eat more memory
[9:02] <Gordio> irssi best
[9:02] <dr_willis> figured out how to move all bans and modes to a seperate window the other day. ;) so i dont see those messages any moar either
[9:02] * debenham (~cjd@ Quit (Client Quit)
[9:03] <axion> depends which plugins you have loaded, but irssi with all the features i need actually uses more ram
[9:03] <axion> disable the programming languages you do not need
[9:03] <axion> much less ram
[9:04] <dr_willis> weechat seems to be using 6% of my ram here
[9:04] <dr_willis> according to htop
[9:04] <axion> 6% is relative
[9:04] <axion> not a real size :P
[9:05] <dr_willis> i cant memoprize the big memory # htop is printing and type it back .. ;)
[9:06] <axion> mine is using 5% of 119M total ram
[9:06] <dr_willis> i dont even know what my memory split is
[9:06] <axion> htop says

[9:08] <axion> i'm connected to 3 networks and have 10 buffers using less than half that amount

[10:12] <dr_willis> there were a few neat bits.. but over all - barely worth the $5 i think i spend on the kindle version
[10:13] <wakoinc> I'm trying to think what resources are lacking re RPi
[10:13] <dr_willis> I really need to look into more hardware hacking on my pi. ;) but ive little time. so i just play with the raspban stuff
[10:14] <wakoinc> I guess I haven't seen any learn to program while doing something guides.. most just show you code
[10:14] <dr_willis> wonder how hard it is to add just a simple button. ;) that will run a script or somthing.
[10:14] <dr_willis> I rarey code. rarely need to
[10:14] <wakoinc> yeah, i am mostly after hardware hacking atm
[10:15] <dr_willis> I have very little hardware hacking needs. ;) but a few buttons on my pi case.. would be nifty. if they are easy to get going.
[10:15] <dr_willis> one for play/pause/next or perhaps one for 'reset' ;)

[10:32] <wakoinc> ruby is actually really nice to use

[10:33] <dr_willis> i recall some ruby gui/tutor app on windows ages ago that let you make some neat little apps in a few clicks.. but i cant recall its name.
[10:33] <dr_willis> but i rarely need to code much these days anyway
[10:33] <wakoinc> id stick to python and ruby for programming pi stuff
[10:33] <wakoinc> flexible, work for server and web stuff, strong communities, etc
[10:34] <dr_willis> i have actualy used Rexx the most over my lifetime. ;) good old amiga days
[10:34] <dr_willis> theres features of perl and python i would of loved to have years ago.

[10:45] <Tachyon`> but the lcd cable was goign through the damaged hingeo n the old case

[11:23] <Tachyon`> you'd haev to actually setup a network if you're just connecting them with a cable, I don't think the pi cares if the cable is crossover or not so there's that at least

[11:50] <earl2> hi - is the raspberry gpu suitable for general purpose compute?
[11:51] <Xark> earl2: Not really. OpenGL ES.
[11:52] <earl2> the faq happens to say the gpu "is capable of 1.5texel/s or 24 GFLOPs of general purpose compute" but i guess it's not actually available for such?
[11:52] <earl2> opengl es doesn't have compute functions does it? (like opencl does?)
[11:53] * GentileBen (GentileBen@cpc20-lutn10-2-0-cust20.9-3.cable.virginmedia.com) has joined #raspberrypi
[11:53] <Xark> earl2: The API is OpenGL ES. It is possible to express your "problem" as textures and run a shader over them to compute, but it isn't ideal.
[11:54] * cvr (~quassel@unaffiliated/cvr) Quit (Read error: Connection reset by peer)
[11:54] <Xark> earl2: Under the covers, the GPU is a powerful vector/risc cpu, but it is all proprietary.
[11:54] <earl2> so, just to throw this out there. let's say i want to do stereoscopy operations from two web cams for 3d facial gesture recognition
[11:55] <earl2> do you think I can do it?
[11:55] <Xark> earl2: No OpenCL support.
[11:55] <Xark> earl2: Sure. I suspect the GPU may be helpful for that (especially vs slow main CPU on RPi).
[11:55] <earl2> I would think the arm chip is way underpowered, but at like 640x480 r even 320x240 times two, the input is WAY slower than the graphics the gpu is normally pushing around
[11:55] <earl2> right, exactly
[11:56] * monkeycoder (~monkeycod@ has joined #raspberrypi
[11:56] <earl2> so, Xark, how would you go about designing this? I mean, on a normal pc I would just do it in c with whatever libraries i find or make, I would't even bother with acceleration since it's only 640x480 or whatever. but now on the pi I should... could you walk me thorugh how I might do that?
[11:56] <Xark> earl2: If you have a RPi take a look at the hello_pi examples (they show a realtime computed mandelbrot, for example).
[11:57] * ukgamer|away is now known as ukgamer
[11:58] <Xark> earl2: Well, do you understand GPU shaders? Basically a program that takes pixels from texture(s) as inputs, does some computations and writes pixels to an output. Usually it computes lighting and stuff, but you can compute anything. Not good for "brancy" algorithms (but yours sounds like "bulk" parallel ops, which is is good at).
[11:58] <Xark> branchy*
[11:58] <Davespice> morning folks
[11:59] <Xark> So you setup the textures and output target and "draw a big quad" and it will operate on the 2D array of pixels (and each pixel can be like floatx4).
[11:59] <earl2> right, mine isn't branchy at all. however, perhaps i want to keep track of the last 10 frames on each camera or whatever.
[11:59] <earl2> how much "video ram" does the rpi have?
[12:00] <Xark> earl2: Shared with main RAM, so on newer 512MB Pi, you can do 256/256 (or even give more to GPU I think).
[12:01] <dr_willis> i think mines using 128 for video.
[12:01] <earl2> Xark, I don't have a physical rpi yet, however I have a vm under windows that from looking online is only a hair faster (benchmarks are maybe 10% faster than baselines i see online for rpi). so i will have to wait and get one, however it sounds like it oculd work
[12:02] <earl2> Xark, do you know anything about this stuff? If I try to write my algorithm as shaders, is there any hance you can help me if I get stuck? It's something I've never done before...
[12:02] <Xark> dr_willis: For most purposes, that is probably plenty.
[12:02] <Xark> earl2: Google is your friend. :)
[12:02] * Lupinedk is now known as lupinedk
[12:02] <axion> dr_willis: prob 160 actually if you have ~350 sys still
[12:03] <Xark> earl2: I am a game developer, so I am familiar with this stuff, but it is not my main area of interest (and especially not general purpose computation with GPU).
[12:03] <dr_willis> yea' ive not tweaked it. so irs the rasbian default
[12:06] <earl2> ah, okay
[12:06] <earl2> well I might just get general tips, but thanks :)

[16:19] <prjkt> hi. so I saw some threads about horrible fps from web cams over usb.
[16:19] <prjkt> I was wondering if it were posisble to use a low res, black and white web cam so that very little info gets pushed across the bus
[16:19] <prjkt> what do you guys think? can cmos usb cams be read in black and white mode?
[16:19] <SpeedEvil> no
[16:20] <SpeedEvil> not usually
[16:20] <prjkt> oh
[16:20] <prjkt> i'm surprises, dince you know they can do all these encodings and have all these modes
[16:20] <prjkt> surprised*
[16:20] <SpeedEvil> they are very limited in modes typically

[16:21] <prjkt> I really need higher fps. and I need two read two cameras at a time. and the pi has some other processing to do.

[16:22] <prjkt> that sounds very complicated.
[16:23] <prjkt> SpeedEvil, any ideas?

[16:47] <Amadiro> prjkt, depending on what you want to do, you might be able to get around the problem (by not showing the stream on-screen at all, or by using hardware-accelerated decoding, for instance)
[16:47] <Amadiro> it all depends on what you want to do with the data and where it's supposed to go afterwards
[16:48] <prjkt> okay, so what I want to do is kind of like stereo processing on two web cams

[16:48] <prjkt> i think high fps will help, as for example if there is movement or turn compared to the camera, then this is very good information for reconstructing the 3d facial information
[16:49] <prjkt> but since people report like 5-15 fps with a single camera, i'm apprehensive
[16:49] <factor> cool got vlc audio and video working
[16:49] <Amadiro> prjkt, what do you want to do with the data afterwards, show it on the screen?
[16:50] <axion> anyone get pcsx-rearmed to work?
[16:51] <Torikun> factor: vlc works now?
[16:51] <Torikun> when did that happen
[16:51] <prjkt> Amadiro, no I just need the data. it doesn't need to be shown again.
[16:52] <prjkt> in theory, the two web cams could be two black and white cmos chips on the same board as a soc, and the soc should be able to do the calculation and then send me a very low-bandwidth reduction for the pi to work with.
[16:52] <Amadiro> prjkt, so where is the data supposed to go, then
[16:52] <prjkt> but that's in theory
[16:52] <prjkt> it goes to the pi
[16:52] <prjkt> the pi uses it along with other data
[16:52] <Amadiro> which does what type of calculations on it
[16:52] <prjkt> a
[16:53] <prjkt> oh just normal slow calculations, nothing fancy

[16:53] <prjkt> the point is that the pi needs the 3d information about the facial movement. the rest is pretty easy
[16:53] <prjkt> (in software)
[16:53] * oldtopman (~oldtopman@unaffiliated/oldtopman) has joined #raspberrypi
[16:53] <Amadiro> prjkt, well, the CPU on the pi is very slow. You might be able to do this successfully if you can offload as much of the work to the videocore as possible, but if you do any kind of expensive operations on the image data that you do on the CPU, you probably won't get the greatest framerates anyhow
[16:54] <prjkt> I'm pretty sure it's not powerful enough to work with the full color streams, nor is it necessary though
[16:54] <Amadiro> so you'd definitely want to utilize hardware-side decoding of the stream and such, I reckon
[16:54] <prjkt> No, Amadiro - absolutely no expensive operations on the CPU. By the time it gets to the CPU it is massively reduced, to just a few bytes of useful information about the 3d image.
[16:54] <Amadiro> where's that reduction supposed to happen?
[16:55] <prjkt> Amadiro, what do you think, would it be possible for me to build a specialized circuit board that take the cmos images in real-time (30-60 FPS) does the gpu-intensive operations and runs the 3d reconstruction algorithm, and then just sends the (very small) results over usb or serial to the pi?
[16:55] <prjkt> or would I need a whole separate computer to do that?
[16:55] <Amadiro> sure that's possible, the question is mainly how much work you want to put into it, how flexible you need it to be, etc
[16:55] <prjkt> Amadiro, the reduction can happen anywhere I can code the stereoscopy algorithm... be that pi, gpu, or something specialized if this is feasable
[16:56] <Amadiro> you can always slap a bunch of FPGAs on some board to do all the heavy lifting for you, but it's a lot of work
[16:56] <prjkt> Amadiro, I'm surprised you say it's possible. How would I do it?
[16:56] <prjkt> that's interesting.
[16:56] <Amadiro> so I think it'd pay off to first try whether you can just do everything inside the pi, using hardware-decoding of the streams and then seeing whether you can do your algorithms for the reconstruction on the CPU
[16:56] * dumbsdirt (~dumbsdirt@cpe-076-182-043-163.nc.res.rr.com) has left #raspberrypi
[16:57] <Amadiro> and whether the resulting framerate and resolution you can run this with work for you
[16:57] <prjkt> Also, do you think there are any USB cameras that happen to have chipsets that I can try to re-flash (maybe open source), meaning that they already do some kind of processing on-board, and I can just rewrite the software to do my processing instead and send that as data? Or is this a pipe dream?
[16:57] <prjkt> I agree, Amadiro.
[16:57] <prjkt> Where you say, "Hardware-decoding of the streams" how can I make sure that this is hardware? (Happens on the gpu)?
[16:57] <Amadiro> once you start pulling in an external custom PCB with huge chips on it (possibly even FPGAs) we're definitely talking about very high costs and lots of development time
[16:58] <prjkt> I really only know how to program in c, c++, etc. don't know any special gpu libraries.
[16:58] <rubiconjosh> prjkt, What you are talking about is possible, but if you are not sure how you would even start it, then it is most likely too complex of a task for you. You would need an extreme understanding of the algorithms you want to implement and if you go the FPGA route you would need to really know HDL, not just sort of know it.
[16:58] <prjkt> Amadiro, how much do these fpga's cost?
[16:58] <Amadiro> prjkt, I don't know much about *de*coding video on the pi, but supposedly the videocore can do it and has interfaces for high-definition cameras and such
[16:59] * AeroNotix (~xeno@abos254.neoplus.adsl.tpnet.pl) has joined #raspberrypi
[16:59] <rubiconjosh> You can price out FPGAs, they are not too expensive, the development boards that let you write them are expensive
[16:59] <Amadiro> prjkt, the question is not really how much fpgas cost, the question is how many years of time you have to spare to learn how to use them
[16:59] * axion (~axion@cpe-67-242-88-224.nycap.res.rr.com) Quit (Quit: WeeChat 0.4.0-dev)
[16:59] <Amadiro> or how much money you have to employ someone who already knows how to use them
[17:00] <prjkt> rubiconjosh, this is very useful feedback. However, if I can do something like prototype with a "stand-in" for that component - hell, it can be a $200 dev board from AMD with dual-core cpu and radeon graphics - just KNOWING that someone else could get this down to a specialized pcb that would be cheap to manufacture, this would help as well.
[17:01] <prjkt> this is the dev board i mentioned - http://hackaday.com/2013/01/26/gizmo-board-a-tiny-x86-dev-board/
[17:01] <Amadiro> cheapest will definitely be to do it all on-chip on the pi or to have some codec chip that can do the decoding for you
[17:01] <rubiconjosh> prjkt, take a look at this page, it is one of the very basic first things you will do when processing computer vision, do you fully understand the math on this page? What you are talking about it implementing more complex math than this with logic gates. http://en.wikipedia.org/wiki/Gaussian_function
[17:01] <prjkt> Amadiro - how can I use a "codec chip" with the pi?? Isn't this what we've been talking about with the fpga?
[17:02] <prjkt> No, I don't "fully" understanding Guassian functions.
[17:02] <Amadiro> prjkt, it depends on a lot of factors, presumably the codec chip will have some way to interface with the camera, and then throw out some-format-or-other (you need to choose the appropriate format here that is useful for you) then that codec chip outputs the data to you via LVDI or so
[17:02] <prjkt> I see.

[17:02] <Amadiro> so then you have something like an FPGA that can interface with that, process the data in the way you want and then send the results out via some low-speed bus or usb
[17:03] <Amadiro> but it really depends on what you want to do exactly, and the whole setup is fairly inflexible
[17:03] <prjkt> Well, guys, I mean what I'm REALLY talking about is that my skills are such that if I have the last 200 frames from each of 2 cameras, then I can run other people's C libraries on them and get the data I need.

[17:03] <prjkt> So, how should we translate to doing that on the pi? Try to do it on-board after getting full FPS image data from both cameras?
[17:03] <prjkt> Amadiro, the inflexibility doesn't bother me, really.
[17:04] <rubiconjosh> I am learning to use opencv and process video, instead of doing the processing on the Pi I am going to use mjpg-streamer to send the webcam video over the network where my desktop with a CUDA enabled OpenCV build will do the processing and send commands back over the network to the Pi. If the Pi does not have the power to do the processing you want you may want to try something like this.
[17:05] <prjkt> wow that sounds intense. I wouldn't have thought the PI Has that kind of bus bandwidth
[17:05] <prjkt> I mean it's only at 700 megahertz.
[17:05] <Amadiro> prjkt, ideally you'd get image data from the cameras (which is likely in some codec that you cannot use directly), use an openmax il client or so to get the videocore to decode it into something that you can use (if it can do that) and then try to do the processing on that on the CPU
[17:05] <prjkt> rubiconjosh, have you tried to see if the usb-to-network translation can be done fast enough by the pi?
[17:06] <prjkt> I don't know if it has "DMA" type operations to copy usb directly to the nic without processing each and every single bit through the slow cpu
[17:06] <Amadiro> it does not
[17:06] <prjkt> on rubiconjosh's goal, Amadiro, don't you think that it might have higher io requirements than he can get?
[17:06] <Amadiro> even worse, everything has to go through userland and back
[17:07] <prjkt> wow
[17:07] <rubiconjosh> prjkt, I plan on using a webcam that outputs mjpg, then all the Pi is really doing is sending a bunch of jpegs over the network from a small webserver. I do not have the camera yet, but I did compile mjpg-streamer on the Pi and did some tests, a 640x480 test stream uses less than 1% cpu and less than 1% of memory. So it should work out no problem, the goal is to do all the heavy processing on my desktop
[17:07] <prjkt> Amadiro, well, he could probably put something in the kernel to do it. people have put web servers in there..

[17:08] <rubiconjosh> prjkt, it was a series of three test images at 20 fps, I have seen some data from someone doing the exact same thing from a webcam that got 30fps still using less than 1% cpu and ram

[17:09] <prjkt> rubiconjosh but if the stream is compressed are you sure that it's actually a full-sized steram? I mean, if the stream has any memory at all it can compress the stream by saying "okay, now the same as two images ago, okay, now the same as one image ago..." and so on, and just send 1 keyframe every so many frames...
[17:09] <Amadiro> prjkt, but as I said earlier, the busses won't really be your bottleneck here, de-coding and en-coding is probably the killer (and maybe the calculations you want to do on the results, which I don't know about, of course)
[17:10] <prjkt> That's what I would expect if I did that and saw 1% cpu usage.. I would try a more complicated video with less repetition :). But maybe you know more than me.
[17:10] <prjkt> Amadiro, no, the resulting computations aren't very intense. it's not a lot of data and not very precise.
[17:10] <factor> `Anyone know where i cna get an image of OpenWebOS
[17:11] <rubiconjosh> prjkt, good point, I do not think so. The way mjpg-streamer works is it gets a request on port 8080 or whatever you set up, then keeps sending jpeg after jpeg until the connection is closed. You can view this with a browser or special software written to accept it, there is nothing about this method that looks like it supports what you are talking about
[17:11] <prjkt> someone in #electronics said this: "" i'm saying it's a known issue for many years that you can't run 2 usb cams on one port, even at fairly low res/framerates" (about usb on pc's). do you agree?
[17:11] <Amadiro> prjkt, well, then just start by researching connecting webcams to the rpi (possibly using the CSI interface) and decoding on the videocore

[17:12] <prjkt> ah, okay rubiconjosh
[17:12] <prjkt> yes doing so
[17:12] <prjkt> one thing, a lot of people said high powered usb hub really helps
[17:12] <rubiconjosh> I just conencted to my mjpg-streamer from a terminal and did a request and it just keeps pushing data through with the test images, never stops or gives small repition like commands
[17:12] <prjkt> do you have recommendations here? how much is one, and should i really look into them or is any powered usb hub ok?
[17:12] <prjkt> rubiconjosh, then cool :)
[17:13] <prjkt> rubiconjosh, maybe i'm being paranoid due to quotes like the above!! :)
[17:13] <rubiconjosh> http://i.imgur.com/5HmjD1p.png <- screenshot showing the small usage with the test images
[17:13] <Amadiro> prjkt, if you end up connecting the cameras via usb, check out what modes the camera supports, most cameras have several usb bulk endpoints that allow you to get different quality output streams
[17:13] <Amadiro> lsusb/usb-devices and libusb(x) help you in figuring out exactly what the usb camera does for you
[17:14] <prjkt> ah okay
[17:14] <rubiconjosh> I do not know much about cameras honestly, I use the built in crappy webcam on my laptop for my opencv stuff, I will be buying a 720 camera for this Pi, but I have never tried or looked into running two cameras on one USB controller.
[17:14] <Amadiro> if things are too slow, you might be able to use a lower-quality output EP
[17:14] <Amadiro> but again, ideally you'd get something you can feed into the videocore for hardware-accelerated decoding
[17:15] <rubiconjosh> If you do try to go the route I am with the image processing happening on a desktop then you are going to want a camera that can output mjpg, then the Pi does not have to do any processing, it will save a lot of cpu time on the Pi for other tasks.

[18:33] <LilSnoop4> that link to the power supply i got that cause i saw reviews that people liked that and it powered it will
[18:35] <mjr> despite the amperage, it is possible that the power supply doesn't give quite (stable) enough voltage - the pi is somewhat fussy that way :(
[18:35] <shiftplusone> 'amperage' O_o
[18:36] <shiftplusone> is that some regional term?
[18:36] <ryanteck> I only remember it possibly being too high as the safety sheet from Farnell said 1.5 amp recommended max
[18:38] <shiftplusone> LilSnoop4, you're rebooting because wifi dongles take too much power, so you're tripping the polyfuse on the raspberry pi input.
[18:39] <ryanteck> Does that still happen on the Rev 2 Ones?
[18:39] <shiftplusone> yes, it's worse on rev2
[18:39] <ryanteck> Ahh
[18:39] <shiftplusone> On rev1, the usb-side polyfuse would trip and prevent the usb device from working
[18:40] <shiftplusone> on rev2 the input polyfuse is tripped so the raspberrypi reboots completly
[18:40] <ryanteck> Ahh
[18:40] <LilSnoop4> ok, so what must i do then shift... something i can go get from the store
[18:40] <shiftplusone> A powered hub may help
[18:40] <shiftplusone> alternatively if you like living on the edge, short out the polyfuse.
[18:41] <shiftplusone> or power the pi through gpio
[18:41] <ryanteck> I shorted out the polyfuses on the USB Side but never the main input
[18:41] <shiftplusone> same here
[18:42] <LilSnoop4> it may help... what would you do i can't run a cable cause im keeping it in my bedrood
[18:42] <shiftplusone> The safest mod is to run two wires straight from the input 5v/gnd pins to the usb 5v/gnd pins. That way the current goes through the wires rather than the internal traces.
[18:42] <LilSnoop4> room
[18:42] <ryanteck> Not that good at soldering yet
[18:43] <shiftplusone> fair enough
[18:43] <ryanteck> My fine hand motor skills are terrible
[18:43] <shiftplusone> LilSnoop4, I would try a powered hub first.
[18:43] <ryanteck> My wi-fi only mesured at around 150mA
[18:45] <ryanteck> then again I never use wi-fi on mine, Having a router as a hub and two wires from the main router in the house is just about enough for me

[18:49] <linuxthefish> hi, what framebuffer can i use on my lcd TV over composite?
[18:49] <ryanteck> Do you know how many mA the dongle uses?
[18:50] <linuxthefish> the manual says "1280 x 768 pixels", should i set the framebuffer to that?
[18:50] <LilSnoop4> http://www.amazon.com/gp/product/B005CLMJLU/ref=oh_details_o05_s00_i00
[18:51] <shiftplusone> It's not so much how much current it uses when operating, but the bursts of power. Wireless devices tend to have spikes in power usage when packets are sent and when plugged in and powering up. So even though the average might be low, the maximum would be high, and you'd need a scope to see that properly.
[18:52] <LilSnoop4> shift could i get a basic hub from best buy or radio shack that will work
[18:52] <shiftplusone> Don't know, I don't want to guarantee anything
[18:52] <shiftplusone> Don't want you coming back and yelling at me for wasting your money =D
[18:53] <LilSnoop4> i can return there 30 days so no biggie
[18:53] <shiftplusone> Then yeah, it should work.
[18:53] <mark_vh> shiftplusone: these bursts of power, are they still below the MaxPower listed in 'lsusb -v' ?
[18:55] <shiftplusone> mark_vh, I don't think the MaxPower thing means much. You can program any value in and I doubt chinese manufacturers do proper testing to figure it out properly
[18:55] <shiftplusone> it might be a good indicator of an estimate though
[18:55] <mark_vh> ah ok

[19:27] <shiftplusone> Or get it on alibaba =p
[19:28] <shiftplusone> What happens when you manufacture in china =(
[19:28] <mjr> UnaClocker, ooh. Now to solder wires onto its gpio legs ;P
[19:28] <UnaClocker> mjr: Yeah, It's QFN, so it'd be hard, but that is what I was thinking..
[19:33] <ReggieUK> there's nothing wrong with chinese manufacturing
[19:33] * bertrik (~quassel@rockbox/developer/bertrik) has joined #raspberrypi
[19:33] <ReggieUK> there are issues with some manufacturers though :)
[19:34] <shiftplusone> ReggieUK, there is when they turn around and put start selling your product on alibaba. (my understanding of what happened, not sure)
[19:34] * pretty_function (~sigBART@ Quit (Remote host closed the connection)
[19:35] <ReggieUK> for that handheld?
[19:35] <shiftplusone> http://panton.en.alibaba.com/product/722453778-215071285/3_5_inch_HDMI_game_console.html
[19:35] <ReggieUK> the one that looks suspiciously like a china clone of a psp? :D
[19:37] <shiftplusone> a little, yeah
[19:38] <ReggieUK> and slightly disingenuous moaning about an open source device that runs emulators, part of the major reason why it exists is to use copyright material (I know that you can use 'free' roms etc. but lets face it, I doubt very few people actually own those roms legally)
[19:38] * shirish (~quassel@unaffiliated/shirish) has joined #raspberrypi
[19:39] <shiftplusone> Maybe slightly
[19:39] <ReggieUK> lol :D
[19:39] <shiftplusone> but it doesn't just run emulators obviously
[19:40] <UnaClocker> How many old roms have been tossed in the garbage? How many of these original authors/programmers would actually see money if a couple of enthusiats bought their antiquated roms?
[19:40] * shiftplusone just bought a large collection of c64 software to restore >.>
[19:40] <[Ex0r]> does that use raspberry pi ?
[19:41] <shiftplusone> [Ex0r], no 'course not.
[19:41] <UnaClocker> I've got a stack of NES and Sega Genesis cartridges that don't work, they're simply too old/corroded..
[19:41] <ReggieUK> shiftplusone, I'm not disgreeing with you as such, just pointing out some obvious issues with the whole affair
[19:41] <shiftplusone> UnaClocker, can I have em? =D
[19:41] <UnaClocker> I'm sure you could run C64 software on a Pi rather easily.
[19:41] * ryanteck (~Ryan@fsf/member/Ryanteck) has joined #raspberrypi
[19:41] <[Ex0r]> UnaClocker- buy a genesis and nes rom reader and convert them
[19:41] <UnaClocker> shiftplusone: heh, nah, my wife is holding onto them as some kind of keepsake from her childhood.
[19:41] <shiftplusone> Damn
[19:42] <UnaClocker> :)
[19:42] <shiftplusone> I need to get some sega genesis/megadrive cartridges as well
[19:42] <ryanteck> Genesis 0.o
[19:42] <ryanteck> SNES is the way to go ;)
[19:42] <UnaClocker> I loved my Genesis when I was a kid.. XMen and that Tazmanian Devil game..
[19:43] <ryanteck> Super mario land
[19:43] <UnaClocker> I need to get an adapter to run the Genesis control pads on the Pi, I have like 10 of them for some reason.
[19:43] <x42> my raspi isn't booting anymore - i think because of lack of / memory
[19:43] <shiftplusone> I mostly played Mortal Kombat II ... at least that's the one that sticks in my memory.
[19:43] <x42> is it safe to delete /var/swap
[19:43] <x42> to get 100mb free space?
[19:43] <ryanteck> I got my snes sitting next to my PC, still play it
[19:43] <x42> i mounted the sd card on my other machine

[19:45] <shiftplusone> x42, it should still boot if you run out of space.
[19:45] <mjr> shiftplusone, the alibaba version seems to be a *cough* cheap knockoff, it has less ram, less flash (and curiously less advertised sd capability) than the kickstarter version...
[19:45] <mjr> also less battery
[19:46] <shiftplusone> mjr, I actually doubt the alibaba listing is legitimate to begin with. If you were to order from there, they would probably take your money and you wouldn't hear from them again. Happens quit often on alibaba.
[19:46] <mjr> quite possible
[19:47] <shiftplusone> But from what I understand, the alibaba one has the same codename as the early dev/demo version of gcwzero. I haven't been following the whole thing, so I don't really know. Just find it interesting that things like that happen. =/

[19:53] <DarkKnightCZ> hi, has anyone here tried to create something like "universal player" from rpi? something like inverse dlna (you put movie / music / pictures onto some app on client, then it's streamed into rpi)... i guess there is no app for that, so if anyone has an idea, what protocol use, etc., it would be nice :)
[19:58] <shiftplusone> ryanteck, yes, *science*! Education really, got a uni project to make hardware that will dump/restore old c64 and similar media.

[19:58] <ryanteck> Well the oldest thing in my house is my SNES or Gameboy
[19:59] <ryanteck> Unfortunatly no C64 or other computer
[19:59] <shiftplusone> Yeah, but you're still using those, heh.
[19:59] <piney0> too bad i threw out all mine about a year ago
[19:59] <ryanteck> I would probberbly use a C64 if I had one xD
[19:59] <ryanteck> I think their epic
[20:00] <piney0> had two trs-80's a bunch of games, and old magazines for it
[20:00] <shiftplusone> I know some people in europe have access to cheap C64's through recycling centres and such, but no such luck where I am afaik. Can't find anything for under $100.
[20:01] <piney0> only things i saved are the game 'hacker' and qbert
[20:02] <[Ex0r]> nice, the latest fw version for rpi is my birthday :)

[20:09] <[Ex0r]> led cube kit?
[20:09] <bebraw> yeah. basically that would be a controller + leds + sw to control all that
[20:10] <shiftplusone> [Ex0r], a cube of leds... can do cool things visually.
[20:10] <[Ex0r]> oh
[20:10] <[Ex0r]> I want a cool LED screen that displays what movie is currently playing on xbmc
[20:10] * jankyhellface (~jankyhell@ has joined #raspberrypi
[20:11] <shiftplusone> Why LED? Just by a standard LCD character display and hook it up.

[20:11] <[Ex0r]> but I want the display to be fancy
[20:11] <[Ex0r]> I like the look of LED where it has the nice dots/lines in it
[20:11] <shiftplusone> Find one with a 3.3v serial controller and it's very straight forward. If not, parallel is doable too.
[20:12] <[Ex0r]> would have to find a way to get xbmc to send it to the controller

[20:43] <UnaClocker> Yeah, I got 4hours 57minutes of life out lapdock the last time I tested it..
[20:43] <UnaClocker> Now I've got a homebrew model A, with significantly lower power consumption..
[20:44] <shiftplusone> I am guessing about 8-9 hours now
[20:44] <UnaClocker> heh, if that's the case it'll still be going when I go to bed. ;)
[20:45] <shiftplusone> They did say the lan chip can use almost half of the power, so I am just basing it on that.
[20:46] <UnaClocker> Makes sense, my current draw test showed 320ma on the meter with that chip, and 120 after removing it.
[20:46] <shiftplusone> Do you have something compiling or a graphics demo running, or just idle?
[20:47] <UnaClocker> I'm here in IRC.. In X..

[21:22] <Torikun> sure
[21:22] <bebraw> mmm... speaking of pandora i should hook up spotify one day (euro peep here)
[21:22] <prjkt> hey, so... how come if rpi is a pc, its bus couldn't just have an external video card, if someone wanted to write the code for it?
[21:22] <prjkt> (like nvidia, etc)
[21:23] <rymate1234> It isn't a PC as such
[21:23] <prjkt> but it is...architecturally
[21:23] <chz|bacon> i'm working on getting epeak to work properly, and while it does work, i get this spew of alsa lib errors. http://slexy.org/view/s21aKtHqx2
[21:23] <chz|bacon> maybe someone can point me in a direction
[21:23] <prjkt> so like what marries it to the onboard gpu?
[21:23] <rymate1234> prjkt, it uses an ARMv6 CPU with a broadcom SoC
[21:23] <prjkt> right
[21:24] <prjkt> but it has ram, io like usb, a network card...
[21:24] <rymate1234> but its the cpu that matters
[21:24] <prjkt> why can't it also have an video card if you wanted to attach one? I mean what made that too dififcult to design into the thing?
[21:24] <prjkt> I don't understand... normal laptops that have an onboard intel graphics chip right "in" the cpu can still have discrete graphics if you add it...
[21:24] <tdy> the goal from the start was to trim the cost to what it is now
[21:24] <rymate1234> prjkt, have you ever tried to attach your video card to a mobile phone?
[21:24] <prjkt> No. but mobile phones don't have nic, dram, ... list goes on
[21:25] <rymate1234> a raspberry pi has similar hardware to a cheap android smarphone
[21:25] * dpea (~AndChat29@freenode/sponsor/dape) Quit (Read error: Connection reset by peer)
[21:25] <prjkt> what I mean is that architecturally isn't it "just" a pc? Or could you explain where the change is?
[21:25] <prjkt> so how come it has all these pc-like interfaces then?
[21:25] <bebraw> prjkt: if you want something powerful (but a bit more expensive), look into something like odroid perhaps
[21:25] <Joeboy> It doesn't expose connectors for a gpu
[21:25] <prjkt> so if the foundation wanted, it could have exposed those connectors?
[21:25] <rymate1234> prjkt, it has USB, which is present on a crap ton of devices
[21:26] <Joeboy> It would have to be a quite different beast
[21:26] <rymate1234> the networking is just a usb ethernet card
[21:26] <Joeboy> it's very integrated with the gpu
[21:26] <Joeboy> like, the gpu handles the boot process (which is a bit weird)
[21:26] <prjkt> Joeboy, could you explain why it would have to be so different if it exposed gpu pins?
[21:26] <UnaClocker> prjkt: You can plug a USB video adapter into the Pi.
[21:26] <prjkt> yah that's weird. but you wouldn't have to change the on-board gpu to let some software interface with off-board gpu
[21:26] <prjkt> don't aple laptops like macbooks have both and switch dynamically betwen them?
[21:27] <prjkt> UnaClocker: really...that is very interesting. I thought that wouldn't be possible
[21:27] <IT_Sean> o/
[21:27] <prjkt> UnaClocker, could you be more specific?
[21:27] <tdy> a priority (possibly *the* priority) from the very start was the pricepoint
[21:27] <rymate1234> UnaClocker, you can get usb video cards?
[21:27] * jankyhellface (~jankyhell@ has joined #raspberrypi
[21:27] <UnaClocker> The Pi uses something called a SOC, "System On Chip", which makes things cheaper by not needing external busses like PCI..
[21:27] <tdy> a lot of things *could* have been done
[21:27] <prjkt> (I know normally a usb video card doesn't make sense - e.g. on a laptop - because the bus is too slow. but in my case it just might! :) )
[21:28] <prjkt> UnaClocker, oh I get it. so there is no pci bus at all?
[21:28] <rymate1234> prjkt, exactly
[21:28] <UnaClocker> They're called USB-VGA adapters, but yes, it lets you run a monitor off a USB port.. Linux supports some of them.
[21:28] <Torikun> oh wow
[21:28] <Torikun> neat
[21:28] <tdy> there are plenty of arm devices that are more powerful and flexible.. the RPi just happened to get enormous press (again, in large part due to the cost)
[21:28] <rymate1234> which is why I said it's like a mobile phone
[21:28] <prjkt> okay
[21:28] <prjkt> all right, I get it then.
[21:28] <rymate1234> ever seen a mobile phone with a pci bus?
[21:28] <Torikun> you need multiple pi's for decent performance. http://www.linux-toys.com
[21:28] <rymate1234> prjkt, may I ask - why did you want a video card?
[21:28] <Joeboy> prjkt: maybe you could attach an lcd display? I don't know the details but people seem to do it.
[21:29] <prjkt> it's just so much likea pc, you know? you hook it up to a display, keyboard, mouse, you run normal linux on it, etc. i thought the architecture would be similar then.
[21:29] <prjkt> I wanted a video card because I am going to be processing two web cam streams via opencv and performance is abysmal on cpu-only, as people have reported on pi

[21:29] <UnaClocker> The Pi has an SPI bus, there are some small LCD's that connect over SPI.. It's really only useful as a system status display..
[21:29] <prjkt> e.g. 7-35 second delay and so forth on processing frames.
[21:29] <rymate1234> ah
[21:30] <prjkt> UnaClocker, do these "usb-vga adapters" really act like graphics cards? I mean can you run them via opengl and so forth?
[21:30] <UnaClocker> No.
[21:31] * nils_2 (~nils_2@unaffiliated/nils-2/x-2480262) Quit (Quit: WeeChat 0.4.1-dev)
[21:31] <prjkt> so there aren't any video cards you can legitimately run via usb (or any connection to pi) via opengl etc?
[21:31] <UnaClocker> Use the processor's native h.264 encoder. There's information on it out there.
[21:31] <companion> When XBMC is idle it uses 90% of the CPU Usage of my raspberry PI IDLE wile others report when its IDLE uses about 10 ~ 20% Any ideas?
[21:31] <prjkt> I don't even need the output, I just need the processing help... (so opencv can use them to speed up image recognition).
[21:32] <prjkt> UnaClocker, I don't get to make that choice - opencv doesn't use it on pi.

[21:32] <xzr> oh
[21:32] <prjkt> right now my strategy is to get black and white usb web cams and read them in 320x240 mode, and hopefully that will be enough to process on the tiny cpu.
[21:32] <companion> xzr, http://pastebin.com/GTZ59Juq
[21:32] <prjkt> small enough to*
[21:33] <prjkt> these odroid things..do they support full opengl? (e..g would opencv the vision library be able to use gpu funcitons?)
[21:33] <xzr> maybe you have a broken addon doing some magic or something :E
[21:33] <xzr> just guessing
[21:34] <companion> xzr, broken addons are automatically disabled right?
[21:34] <prjkt> ah, someone asked this question "Does ODROID-X ARM Mali GPU supports OpenCL?"...and the answer is...

[21:39] <prjkt> hi - so I switched to talking about "opencl" but i meant opencv :/
[21:40] <bebraw> prjkt: exynos4412 quad should be one of the better arms you can get atm
[21:41] <bebraw> the board is a little bit expensive, though (depends on budget)
[21:41] <prjkt> just a sec, looking
[21:41] <prjkt> i'm really interested in whether opencv (computer vision library) will be supported, hardware accelerated (gpu)
[21:43] <mark_vh> companion: try disabling rss feed
[21:43] <companion> mark_vh, every thing is minimized RSS/AddonCache is disabled etc
[21:43] <mark_vh> companion: and i once read something about dirty updates of the gui, but never played with that myself
[21:44] <companion> mark_vh, when doing dirty region on 1 it does not make a difference here tho :S
[21:44] <mark_vh> sorry, dirty regions
[21:44] <bebraw> prjkt: if you can't find anything via google, try their forums. in my experience they are very responsive
[21:44] <prjkt> who are?
[21:44] <prjkt> exynos etc?
[21:44] <bebraw> odroid folks
[21:44] <bebraw> at hardkernel.com
[21:45] <bebraw> i'm sure there are many other boards around. that's probably just one alternative amongst many :)
[21:45] <bebraw> raspi is just perfect for some purposes. i'm using it as a little internet radio server for myself :)
[21:45] <mark_vh> companion: they are just discussing CPU load in #openelec, maybe something for you?

[21:53] <pasky> Hi! I'm trying to find information on the default modes of the GPIO pins (input / output direction, pullup/pulldown) - any hints, please?
[21:54] <scummos> i think they're all input by default except for the uart one or so?
[21:54] <scummos> but if you care about a specific condition, why not just set it explicitly in an init script?
[21:55] * KeatonT (~textual@unaffiliated/keatont) has joined #raspberrypi
[21:56] <UnaClocker> Yeah, by coming up as input by default. they're "high impedance" so they don't interfere with things..
[21:56] <pasky> I just want to make sure that e.g. if the user starts up the pi with a button pressed, the gpio pad will not enter an out-of-spec condition.
[21:56] <pasky> input by default is excellent, great

[21:57] <shiftplusone> It's tuesday tomorrow =/
[21:57] <pasky> What about pullup/pulldown, are any connected by default? Or should I use external ones for ESD protection?
[21:57] <ryanteck> Im in the main timezone

[22:08] <ryanteck> that would be a challenge for me

[22:08] <scummos> but it's only one direction
[22:09] <scummos> so a pin can be either in or out
[22:09] <UnaClocker> Just need a hot air rework station. There are some cheap ones from China..
[22:09] <ryanteck> Finest soldering I did was remove the things I have forgot the name of from the pi
[22:09] <scummos> voltage regulators? xD

[22:09] <ryanteck> Cool
[22:10] <ryanteck> The pi to me would be useless without enthernet on
[22:10] <scummos> well with hot air it's quite simple, make it hot and take the component off with a tweezer ;)
