02:54 pizthewiz vade: GL pipeline on Raspberry Pi?
02:54 vade haha yes.
02:54 vade :D
02:54 pizthewiz I knew it!
02:55 pizthewiz Still running into weird state leakage?
02:55 vade no, just perf stuff, and more weird OpenFrameworks shit
02:55 vade and by weird I mean, I suck
02:56 pizthewiz Issue and PR away! :0)
02:56 pizthewiz The Raspberry Pi does seem a little fragile
02:56 vade yea, its weird.
02:56 vade I have two identical machines and once gets half the FPS of the other
02:57 pizthewiz If you didn't need a camera, I wonder if you'd have better luck with one of the other arm boards
02:57 vade I'm at a total fucking loss as to why
02:57 vade Yea I'm wondering
02:57 pizthewiz Oh… memory split?
02:57 vade checked - same
02:57 vade thanks though :)
02:57 pizthewiz Damn, I was hoping for a swish on that one
02:58 vade yea right?? :D
02:58 pizthewiz Same SD card and both rev 2 Model B?
02:58 vade checked tvservice same res
02:58 pizthewiz That is really really weird…
02:58 vade yes both model b's both same distro
02:59 vade oh
02:59 vade wait
02:59 pizthewiz Both the 512?
02:59 vade one is 3.10.27 (faster) and the other is 3.10.32 (slower)
02:59 vade some fucking GL driver thing?
02:59 pizthewiz Ha!
02:59 vade FUCK
02:59 pizthewiz Damn, if so, I totally would have expected that to have been caught by their OS build team
03:00 pizthewiz Seems like their distribution is large enough now that they'd need some serious QA before release
03:00 pizthewiz Think about all those kids in classrooms with half frame rate GL now
03:01 vade well, I mean
03:01 vade I'm totally unconvinced thats it
03:01 vade I also have like
03:01 qDot_ Yeah I can say pretty firmly from the time that I was still allowed to work with kids: kids aren't worth enough money for QA.
03:01 vade zero clue on how to revert, if thats possible
03:01 vade hahaha
03:01 pizthewiz What about kids *as* QA?
03:02 pizthewiz vade: I almost think you have to blast your SD card, I'm not sure if you can unroll dist-upgrade installed stuff
03:02 vade I hate linux.
03:02 vade wait.
03:02 vade Everything. I hate everything
03:02 vade >:-O
03:03 pizthewiz There does seem to be a lot of "oh, just re-image your card" kind of stuff.
03:04 vade god what the fuck
03:04 vade one device is running at 29fps
03:04 vade the other at 15
03:04 vade I AM SO GODDAMNED TIRED OF SECOND GUESSING EVERYTHING ON THIS PLATFORM
03:04 pizthewiz What about stuff like es2gears
03:05 pizthewiz If that reports the same halved framerate… it might be the OS/drivers after all
03:05 admsyn joined #openframeworks
03:06 vade god, I don't even know how to install that. apt-get install es2gears?
03:08 pizthewiz Oh it isn't installed by default, arg
03:09 pizthewiz Hmm, there might be another generic GL app you can use to measure
03:09 pizthewiz glxgears?
03:13 vade ok. so. linux folk really need some goddamned UX / UI hammering over the head
03:13 vade how in the flying fuck does it make sense that apt-cache is what you use to search for packages
03:13 vade apt-cache search .
03:13 vade I mean, I get it. its a cache
03:13 admsyn as opposed to like apt-get list whatevs?
03:13 pizthewiz I know right, that is really annoying
03:13 vade but maybe the apt-get tool should fucking search too? or call it something like 'install"
03:14 pizthewiz yeah, why are there specialized tools for every subtask
03:14 vade unix way but
03:14 vade at least give them semi understandable names.
03:14 pizthewiz Also fun is trying to get a list of packages that are outdated
03:14 vade apt-get list doesn't work on raspberry pi
03:15 qDot_ apt-cache search
03:15 qDot_ Jesus. How is that not obvious.
03:16 admsyn :3
03:16 qDot_ Next thing you're going to tell me git's command line is opaque.
03:17 vade :P
03:18 qDot_ And just in case you need a current mood image for this conversation: http://3.bp.blogspot.com/-dhe4GVlomxo/TauXDspDmlI/AAAAAAAAApM/HVXXaw-Qpu8/s640/vintage%2Bchildren%2527s%2Bbook%2Bi%2527m%2Ba%2Bjet%2Bs%2526s1.jpg
03:18 vade real life lolz
03:18 vade I like you
03:28 vade http://www.phoronix.com/scan.php?page=news_item&px=MTIxNDk
03:32 admsyn "Published on 24 October 2012" wat
03:32 admsyn didn't that come out like a week ago if that?
03:34 qDot_ No.
03:34 qDot_ There's been multiple releases of different things in the stack.
03:35 qDot_ All of them hyped to shit, none of them nearly as useful as hoped.
03:35 qDot_ Because, well, broadcom.
03:42 vade :\
03:51 vade holy fuck me
03:51 vade its the goddamned os
03:51 vade half. fucking. frame. rate
03:56 pizthewiz joined #openframeworks
04:21 vade jvcleave you around?
04:27 jvcleave vade: yep
04:28 vade Man - this shit is like minefield on hard
04:28 vade you do one thing and you're fuuuccckkkkeeedddd
04:28 jvcleave yeah - rpi-update has burnt me in the past
04:28 boltR joined #openframeworks
04:28 jvcleave I only do it now when there is a specific fix I want to try
04:29 vade man, that shit needs a warning flag
04:29 vade god damn.
04:29 jvcleave yeah - I hate when I see tutorials that have you running it
04:29 qDot_ There's a bit of an assumed warning flag around debian and like, other package managers at all ever.
04:30 jvcleave qDot_ yeah - rpi-update is worse in my view as it goes around package manager conventions
04:30 qDot_ Of course, that first assumes you live on debian and pay attention to it's community, and the thought of vade trying to do that for more than 5 minutes is going to keep me entertained for a while.
04:30 vade well, its not a package manager
04:30 vade its more like a 3rd party script that the community says / admits might not belong in there
04:30 vade and doesn't really mention when you update you're getting experimental features.
04:31 qDot_ YEah, I suppose I should expand that to "updatey thingies in general"
04:31 vade ha.
04:31 vade DONT FUCKING TOUCH IT.
04:31 qDot_ 'cause man, the shit that has gone down over pip/gem/etc.
04:31 jvcleave at least debian has unstable, etc that you have to explictly enable
04:31 qDot_ And I /really/ can't imagine the rpi foundation getting this shit right.
04:32 qDot_ Yeah, I live on test and pin out of unstable as needed, but I also make a hobby of seeing how many times I can kick myself in the nuts.
04:32 vade haha
04:33 vade yea, taking update advice from you, is kind of like
04:33 qDot_ Never trust someone who's talking to you on IRC via emacs.
04:33 vade seeing how much I enjoy being kicked in the nuts
04:34 vade or how much you enjoy kicking me in the nuts
04:34 vade just something with my nuts out of my control
04:34 vade I want to be in control of my nuts
04:34 qDot_ I have robots that do that for me.
04:35 jvcleave vade are you using much else but OF?
04:35 vade no, only OF on rPi
04:35 jvcleave yeah - just re-burn the CMU image and move your projects over
04:35 vade ugh. Really? :(
04:35 vade thats so so sad.
04:36 qDot_ Honestly that's a pretty common state of affairs when working with embedded in general.
04:36 vade fucking nerds :P
04:36 qDot_ Fuck the world, overwrite the world, repeat.
04:37 pizthewiz I thought for some reason the voodoo in rpi-update wasn't just stuff that would be in a debian image
04:37 pizthewiz Like on-chip firmware or something?
04:37 pizthewiz I guess just the kernel?
04:37 boltR joined #openframeworks
04:37 jvcleave its not really - it is put on by Raspbian
04:38 vade so jvcleave the CMY image I can apt-get update; apt-get upgrade or no?
04:38 vade er CMU
04:38 pizthewiz vade: if you install htop on both Raspberry Pis, can you spot any differences when running your app?
04:38 jvcleave yeah - that should be fine
04:38 pizthewiz dist-upgrade is dangerous though no?
04:38 jvcleave I don't use it
04:38 vade whats dist-upgrade?
04:38 pizthewiz We need some sort of GL smoke test app :0)
04:39 qDot_ dist-upgrade is for things that require kernel module updates, major dependency changes, etc.
04:39 vade so like 10.8-> 10.9 ? ish
04:39 vade rather than point upgrades
04:39 qDot_ (At least, on actual debian. My rPi's are collecting dust next to my beagle bone black)
04:39 vade (to use layman terms)
04:39 jvcleave dist-upgrade is typically used when you are going from Ubuntu 12.x to 13.x
04:39 vade right, ok.
04:39 vade Gotcha.
04:39 qDot_ Ehhhhhhh sorta.
04:39 qDot_ Oh, on ubuntu, yeah.
04:39 jvcleave like that anyway
04:40 vade just, metaphorically.
04:40 * qDot_ too deep in this shit to speak english anymore.
04:40 jvcleave yeah - Raspbian is at Wheezy - the next version is Jessie
04:40 vade haha
04:41 jvcleave the big deal about Jessie (OF-wise) is that gstreamer 1.0 will be included
04:41 jvcleave right now we have a 3rd party repo that provides it
04:43 pizthewiz The UDOO has a Jessie image and the dependency script got all tripped up with that gstreamer 0.10 to 1.0 change :0)
04:44 pizthewiz The GL driver situation there is ugly enough to ignore it for a (long) while though
04:44 vade I was wondering about the UDOO
04:45 pizthewiz If you want to run Android it might be ok, but they are mega slacking on their other images
04:45 vade but I went with RPI due to price and due to community and OF support
04:45 pizthewiz Seems like they are doing a lot of work to get their camera / touch displays together
04:45 vade since id have to basically bootstrap a whole environment and yea
04:45 pizthewiz (on Android)
04:45 * vade eats a shotgun
04:45 pizthewiz Yep
04:46 pizthewiz I have an ODROID-U3 and have been pretty impressed with it, 2GB RAM, 4 core Exynos 4412…
04:46 pizthewiz If you didn't need a camera, it is pretty decent
04:47 jvcleave The Pi is the only one that has VideoCore (that I know of) so the rest suck for hardware decoding/encoding etc
04:48 pizthewiz Exactly, hardware video decode isn't great on the U3 yet (Android is good, Ubuntu not great)
04:48 pizthewiz It is a minefield out there!
04:48 vade interesting
04:48 vade just simply running an apt-get update; apt-get upgrade seemed to fix it
04:49 vade now I am on um, 3.10.25+
04:49 * vade mutters
04:49 vade I have no idea about anything but fuck if I'm touching that shit again.
04:50 jvcleave I feel your linux pain tho - I spent most of the day realizing why I have been putting off rebuilding my mythtv system
04:51 pizthewiz Weird, is rpi-update the one that jumped the kernel to 3.10.32?
04:51 vade no idea.
04:52 jvcleave I always end up reading endless arguments on upstart vs int only to end up with a blank desktop
04:52 jvcleave init

06:15 jvcleave ?
06:19 LCID_Fire_ joined #openframeworks
06:20 vade ah, camera came loose. Was getting white frames :X
06:23 jvcleave yeah - that cable is finicky - I got this case because it has a tripod mount - much better http://store.mobileappsystems.com/100065
06:23 jvcleave expensive tho
06:27 boltR joined #openframeworks
06:27 vade oh thats nice
06:28 vade shit. I wish I had known about that. Ha
06:29 vade is there any way to allocate > 256 mb for GPU ?
06:30 jvcleave I've done 384
06:38 jvcleave vade: just found an interesting alpha value for overlayed video - trying to figure out how to use it
06:38 vade really you can do 384?
06:38 vade thats awesome.
06:39 jvcleave yeah - I am able to move around video now (not restrained to full screen)
06:40 jvcleave but if you search for "alpha" on this page it is what I am looking at
06:40 jvcleave http://www.jvcref.com/files/PI/documentation/ilcomponents/prop.html
06:42 jvcleave curious of the "layer" aspect as well
06:52 Marsat joined #openframeworks
07:03 jvcleave well - alpha can be true/false - guess that could be useful
07:06 vade oh. just doubled FPS
07:06 vade was doing something dumb in of
07:06 vade awesome.
07:06 vade now close to 60
07:06 jvcleave :)
07:06 vade weeeeeee
07:06 vade I find oF so ... strange :
07:09 jvcleave interesting - i can crop the image as well
07:10 jvcleave this is like playing with an old prosumer vcr without the manual
