[0:12] <Bushmills> JakeSays: schematics are also a kind of "language". more symbolic, granted.
[0:12] * rymate1234 (~rymate@znc.rymate.co.uk) has joined #raspberrypi
[0:12] <JakeSays> Bushmills: right
[0:13] * tanuva (~tanuva@89.204.137.89) Quit (Ping timeout: 252 seconds)
[0:13] * rburton- (~rburton-@50.12.23.145) has joined #raspberrypi
[0:15] <Bushmills> and complex operations will always involve a sequence of actions, because input of one operation will be based on output of another operation, hence not everything can happen in one clock or at the same time
[0:15] <Bushmills> there's a limit to how much you can do concurrently
[0:15] <JakeSays> tell that to the quantumists. lol
[0:15] * tanuva (~tanuva@82.113.99.41) has joined #raspberrypi
[0:17] <Bushmills> they may be able to represent multiple states but not an infinite number of states. they can't - at least not yet - represent the set of all possible programs - and all their possibly outputs - in finite number of information holding devices
[0:17] * dj_pi (~dj@c-107-5-25-243.hsd1.mi.comcast.net) Quit (Quit: Leaving)
[0:18] <Bushmills> but that'd be necessary to calculate a more than trivial operation in one single unit of time
[0:20] <Bushmills> ehm .. there's possibly a flaw in that reasoning
[0:21] * Xark notes that weird internal FPGA delays and stuff make non-clocked FPGA designs very difficult to debug and prone to "glitching" (and/or not too portable). Synchronous tends to be the rule in "robust" FPGA designs (AFAIK).
[0:21] <Bushmills> which is, as the number of atoms - or quarks - in the universe is probably finite, so is the number of possible arrangements of all of them - albeit it's a pretty big number. that should also limit the number of possible programs
[0:22] <Xark> Bushmills: And if the universe is infinite, then you have some clock propagation delay issues. :)
[0:24] * _BigWings_ (~Thunderbi@modemcable237.145-19-135.mc.videotron.ca) Quit (Read error: Connection reset by peer)
[0:25] <chithead> if the universe is infinite, then you also have infinitely many particles due to quantum fluctuation
[0:26] * sjs205 (~sjs205@host109-157-67-241.range109-157.btcentralplus.com) Quit (Ping timeout: 256 seconds)
[0:26] <Xark> chithead: Yes, but it would still be hard to do an "infinitely" complex calculation with them still (and beings have already attempted it an infinite number of times). :)
[0:27] <chithead> well if you have an infinite universe then you also have the infinite monkeys to do your calculation :)
[0:28] * _BigWings_ (~Thunderbi@modemcable237.145-19-135.mc.videotron.ca) has joined #raspberrypi
[0:28] * NimeshNeema (uid2689@gateway/web/irccloud.com/x-dfzvydjixwtcjxfc) Quit (Ping timeout: 264 seconds)
[0:28] * Xark doesn't really believe the universe is infinite (too many silly things pop out of that assumption). I tend to believe in integers. :)
[0:29] * tanuva (~tanuva@82.113.99.41) Quit (Quit: Leaving.)
[0:29] <Bushmills> Xark: the quicklogic devices, later second sourced and then assimilated, i think, by cypress, prided themselves with "predictable timing".
[0:29] <Amadiro> Well, all of our scientific theories rely on space being infinitely divisible, so
[0:29] <chithead> anyway, if the universe is bounded (not necessarily discrete) in some way then we have poincaré recurrence and not arbitrarily many calculations
[0:29] <alexszilagyi> is there anyone here who used django on his PI ?
[0:29] <ozzzy> Xark: the set of integers is infinite
[0:29] <dagerik> ey fellows. i am not getting sound from my pi when using xmbc. both an mp3 file and a video with dolby ac3 failed.
[0:30] <ozzzy> Amadiro: quantum theory says otherwise
[0:30] <Amadiro> ozzzy, only a little, though
[0:30] <Bushmills> they looked down on lattice a bit, considering them just "super GALs", not FPGAs
[0:31] <Xark> ozzzy: Yes, but that is a only a concept. Plenty of things are infinite in concept.
[0:31] <chithead> sometimes mathematicians distinguish between potential infinity and actual infinity (where integers belong to the former)
[0:31] * f8l (~f8l@77.254.91.40) Quit (Ping timeout: 260 seconds)
[0:31] <Amadiro> ozzzy, I haven't studied any QM/QED/QCM/QFT (I switched degrees before I got to that) but all our other theories of electromagnetism etc do not work if space is not "continuous"
[0:31] <chithead> integers, strings, turing machines etc.
[0:31] <Amadiro> chithead, I have never heard "potential infinity", and I have a degree in mathematics...
[0:31] <Xark> Bushmills: That is an interesting tidbit, thanks. :)
[0:32] <Amadiro> chithead, what you usually distinguish between is larger and smaller infinities, and integers are the smallest infinity
[0:32] <chithead> http://en.wikipedia.org/wiki/Actual_infinity
[0:32] * Xark is only an armchair physicist/cosmologist (but a fun subject to follow). :)
[0:33] <Amadiro> chithead, that's a philosophical concept, not a mathematical one...
[0:33] * quaisi (~simon@host-2-96-161-12.as13285.net) Quit (Read error: Connection reset by peer)
[0:33] * mapee (~mapee@host-87-242-29-237.prtelecom.hu) Quit (Quit: Távozom)
[0:33] <chithead> Amadiro: philosophy, logics and mathematics are related to some degree. read the second part about turin machines and mathematicians
[0:34] <chithead> in this distinction, integers are potentially infinite, while cauchy-dedekind real numbers are actual infinite
[0:34] * beet0l (~bangarang@cpe-74-72-87-242.nyc.res.rr.com) Quit (Remote host closed the connection)
[0:34] * MrOpposite (~MrOpposit@unaffiliated/mropposite) Quit (Ping timeout: 246 seconds)
[0:35] * JakeSays chuckles thinking he started a conversation he can't even remotely understand
[0:35] <Amadiro> chithead, yeah, but that's an object in "the philosophy of mathematics" (or whatever you prefer to call it), strictly not a mathematical concept...
[0:35] <Amadiro> much like the argument whether numbers are "real" or not is a subject of the philosophy of mathematics (or whatever) but doesn't concern any mathematician to any large degree...
[0:37] <Amadiro> but anyway, time to watch some more movies on my pi
[0:37] <chithead> many mathematical concepts do not concern any mathematician from a different field
[0:37] <Amadiro> ...but some concepts do not concern any mathematician from any field, and hence cannot be considered to be "mathematical concepts".
[0:37] <Amadiro> there is a difference there.
[0:38] * rburton- (~rburton-@50.12.23.145) Quit (Quit: Leaving...)
[0:38] <Amadiro> anyway, the *important* distinction is the size of your infinity
[0:38] <ozzzy> Amadiro: the wave function of a discrete particle (photon) gives us the em waves we see
[0:38] * Xark 's is about a 7...
[0:38] <Amadiro> because whether your infinity is countable or uncountable makes a huge difference
[0:39] <chithead> there is an entire school of mathematics (constructivism) that has all permissible objects countable, or potentially infinite
[0:40] <Amadiro> yeah, but constructivism is only taken seriously nowadays for the purpose of automated theorem proving/automated theorem validation and such
[0:40] <Amadiro> since it's not very powerful other than that
[0:40] <chithead> well everything that a computer can perform must be constructed in some way
[0:41] * MrOpposite (~MrOpposit@unaffiliated/mropposite) has joined #raspberrypi
[0:41] <Amadiro> yeah, hence its application in ATP/ATV
[0:41] <Xark> chithead: Although, that brings the conversation back to quantum computing perhaps. :)
[0:41] <Amadiro> But you can't -- unfortunately -- do any interesting math in a constructivist setting
[0:41] <chithead> quantum computers cannot compute more than "normal" ones, only faster
[0:42] <chithead> it is very limiting indeed. but high school calculus is possible
[0:42] <Xark> chithead: Yeah, that is a good point.
[0:42] * guiambros (~guiambros@z65-50-88-217.ips.direcpath.com) has joined #raspberrypi
[0:43] * deep13 (~deep13@c-71-56-122-103.hsd1.ga.comcast.net) Quit (Quit: ...)
[0:43] <dagerik> ey fellows. i am not getting sound from my pi when using xmbc. both an mp3 file and a video with dolby ac3 failed.
[0:43] * ynot (~tony@pool-173-71-108-23.cmdnnj.fios.verizon.net) Quit (Ping timeout: 264 seconds)
[0:44] <Bushmills> i'd consider it possible that there could be computers which aren't constructed but the result of self-organizing processes
[0:45] * ynot (~tony@pool-173-71-108-23.cmdnnj.fios.verizon.net) has joined #raspberrypi
[0:45] * chithead wants a right-accelerated turing machine
[0:46] <Bushmills> maybe i shouldn't say "computers" but devices/entities which are capable of doing computation
[0:46] <Xark> Bushmills: You mean like us? :)
[0:46] <Bushmills> out concept of computers may be too narrow
[0:46] <Bushmills> our
[0:47] <Bushmills> Xark: not sure - some may be offended being called "a computer"
[0:48] <chithead> Bushmills: maybe this kind of computer http://www.technologyreview.com/view/415054/how-entanglement-could-be-deterministic/
[0:48] <Bushmills> though it was a profession at a time
[0:48] <chithead> a model of the universe as cellular automaton
[0:48] <Xark> Bushmills: I (personally) ignore those objections (but to each his own). ;)
[0:48] <Xark> ^ would
[0:50] * Xark is fascinated by the "holographic principle" stuff and could see "everything" being a cellular-automation on some "event horizon".
[0:51] <Bushmills> chithead: maybe, yes. though i was more trying to object to the assertion that computers or anything they perform must necessarily be contructed
[0:51] <Bushmills> structed
[0:52] <chithead> ok, then I rephrase. everything that you program into a computer is subject to constructivist rules
[0:52] * hydroxygen (~duckinaro@unaffiliated/zor/x-4290728) Quit (Quit: Living on Earth may be expensive, but it includes an annual free trip around the Sun.)
[0:53] <Bushmills> does that include the output, the results, that what i program into it generates?
[0:54] <Amadiro> you can make a computer deal with nonconstructivistic concepts much like a human can deal with them
[0:54] <Amadiro> the issue is not so much with the computer as with the algorithms you want to apply
[0:54] <Bushmills> i wonder whether some techniques for generating genetic code could do that
[0:55] * javiolo (~javier@unaffiliated/javiolo) Quit (Quit: javiolo)
[0:55] * satellit (~satellit@c-24-17-64-6.hsd1.wa.comcast.net) has joined #raspberrypi
[0:55] * sjs205 (~sjs205@host109-157-67-241.range109-157.btcentralplus.com) has joined #raspberrypi
[0:55] <Amadiro> you can certainly tell a computer "here, have this set x" which is not constructible, tell it something about its properties, let the computer deduce some more properties, and then maybe query it for properties, much like a human can.
[0:55] <Amadiro> but that's not so interesting, really
[0:56] <Bushmills> essentially, grab some noise, execute it, repeat huge number of times, keep the best performer
[0:56] <Amadiro> Bushmills, with what fitness function?
[0:56] <Bushmills> just the criteria describing the desired outcome
[0:56] <chithead> but the rules are all constructive and potentially infinite
[0:57] <Bushmills> what rules :)
[0:57] <chithead> the rules governing your nonconstructive concepts
[0:57] <Bushmills> the noise generator?
[0:57] <Amadiro> Bushmills, just knowing the desired outcome isn't enough, your fitness function for genetic algos/hill-climbing/etc need to be smooth
[0:58] <Xark> I remember when A-life was a hot subject (80s perhaps). I haven't heard of too much useful coming out of it (but I think the technique has "discovered" a few interesting things perhaps over the years).
[0:58] <Amadiro> Bushmills, you can't just have a genetic algorithm that draws random pixels, give it an image of the mona lisa, and say "if you got this picture, you're done" -- you need to give it a gradual function that tells it it is getting closer
[0:58] <Bushmills> that's just a matter of efficiency
[0:58] * xCP23x (~xCP23x@149.241.236.103) Quit (Read error: Connection reset by peer)
[0:58] <Amadiro> Bushmills, it is for an image of the mona lisa, because you only have a finite set of possibilities, yes
[0:59] <Amadiro> often you're not that lucky
[0:59] <Bushmills> ok, i said "keep best performer", not "keep the single one perfect performer"
[1:00] <Amadiro> Bushmills, yeah, but now the big question is "what is the best performer"?
[1:00] <Amadiro> you need to somehow decide that
[1:00] <Bushmills> so that implies some mechanism allowing to judge the quality of output
[1:00] * rikai (~rikai@unaffiliated/rikai) has joined #raspberrypi
[1:00] <Amadiro> yes, and the mechanism needs to be a continuous function
[1:01] <Amadiro> well, it doesn't *need* to be, but it certainly helps, anyway
[1:01] <Amadiro> otherwise you're kinda back to guessing
[1:02] <Bushmills> but that's merely applying an algorithm to determine how close we got to the desired result, not how we achieve it.
[1:02] * m8 (~mor@unaffiliated/m8) Quit (Read error: Connection reset by peer)
[1:02] <Xark> Quite a bit different to come up with a "random algorithm" that makes Mona Lisa, vs a generational algorithm (even with a crappy fitness function).
[1:03] * loadbang (~loadbang@host81-159-228-14.range81-159.btcentralplus.com) Quit (Quit: Bye)
[1:03] * teepee (~teepee@p4FFFD29A.dip0.t-ipconnect.de) Quit (Ping timeout: 252 seconds)
[1:03] <Amadiro> Bushmills, yeah, but you need it for a genetic algorithm -- a genetic algorithm is a generic way to turn a fitness function ("algorithm how close you got to the desired result") into a construction ("how we achieve it")
[1:03] * teepee (~teepee@p4FFFDA48.dip0.t-ipconnect.de) has joined #raspberrypi
[1:03] <Amadiro> (the generality comes with a lot of caveats attached to it, however)
[1:04] * oldtopman (~oldtopman@unaffiliated/oldtopman) Quit (Quit: *poof*)
[1:04] <Bushmills> yes, there's an optimizing and gradual refinement component in common genetic code generating techniques which isn't present with my noise function example
[1:05] * ukscone (~Adium@cpe-24-193-113-179.nyc.res.rr.com) Quit (Ping timeout: 256 seconds)
[1:05] <Bushmills> my noise generator would be more like the famous monkey composers
[1:05] <Bushmills> or typewriting monkey
[1:05] * ukscone (~Adium@cpe-24-193-113-179.nyc.res.rr.com) has joined #raspberrypi
[1:05] <Bushmills> monkeys
[1:05] <SpeedEvil> really got cup of tea
[1:06] <Bushmills> those also lack an impulse saying "you're getting closer"

[1:53] <Bushmills> the psion 5 had an interesting use for its lcd screen: lacking a temperatur sensor, the screen was used as such
[1:55] <xclusive585> oh that's very clever
[1:55] <Bushmills> it worked by exploiting the fact that contrast shifted with temperatures. user had so set contrast such that two areas - back- and foreground filled - showed similar to identical brightness. the setting where that was the case was the temperature readout

[2:08] <Matt_O> woohoo, I finally got some code working that decodes JPEG (via openmax) directly to EGL texture then renders it. After turning off wait4vsync, I am getting over 100 frames/second
[2:08] <Matt_O> now that's fast! :)

[2:08] <Matt_O> not overclocked either.. just regular pi settings

[2:10] <Matt_O> 720x240 (1 NTSC field), a little under 80k
[2:11] <Matt_O> I am working on an NTSC renderer hence why I am doing fields
[2:11] <Matt_O> I am also swapping the destination texture each render
[2:11] <Matt_O> and it is only hurting performance by a few FPS (like 2-4)
[2:11] <Matt_O> so I am happy
[2:12] <linuxstb> So this is mjpeg? Or does that not support interlaced streams?
[2:12] * piney0 (~piney@unaffiliated/piney0) has joined #raspberrypi
[2:12] <Matt_O> nope, this is my own video format
[2:12] <Matt_O> based on jpeg
[2:12] <linuxstb> Did you try software decoding?
[2:12] <Matt_O> hehe.. yes... it's a joke
[2:12] <linuxstb> I'm curious to know the difference between CPU and GPU jpeg decoding.
[2:12] <Matt_O> GPU: fast, CPU : dog slow? :)
[2:13] <linuxstb> Was that doing YUV to RGB on the CPU as well though?
[2:13] <Matt_O> the pi's cpu is pretty weak to be frank
[2:13] <Matt_O> nope.. the GPU does it all
[2:13] <linuxstb> I mean when you used a software JPEG decoder
[2:13] <Matt_O> oh
[2:13] <Matt_O> yeah
[2:13] <Matt_O> it does the colorspace conversion on the cpu
[2:14] <Matt_O> I may clean up my code and post it as a sample on the forums
[2:14] <Matt_O> may...
[2:14] <linuxstb> I experimented with software MPEG-2 decoding (doing YUV to RGB on the CPU), and that worked relatively well, for PAL (720x576) streams up to about 4Mbits/s (i.e. decoding and displaying faster than 25fps)
[2:14] <Matt_O> it needs some work :)
[2:15] <linuxstb> Sorry, I meant YUV to RGB on th GGGGG PU
[2:15] <Matt_O> I made one attempt at software mpeg2 decoding
[2:15] <Matt_O> it segfaulted
[2:15] <Matt_O> I did not make any further attempts :)
[2:15] <Matt_O> if I make a serious effort, I will go through openmax
[2:16] <Matt_O> why software mpeg2 decoding? you don't want to pay for the license?
[2:16] <Matt_O> isn't it like $4 or something? hehehe
[2:16] <linuxstb> This was before the license was available
[2:16] <Matt_O> oh ok
[2:16] <linuxstb> But yes, as soon as it was, I gave it up

[2:19] <Matt_O> back in August I shared how to decode JPEG to a buffer: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=33&t=15463
[2:19] <Matt_O> I've been wanting to revisit that for a while
[2:19] <linuxstb> How are you handling de-interlacing? One thing that's annoying me with the Pi is that it can't sync fields correctly when outputting interlaced content in an interlaced video mode.
[2:20] <Matt_O> I am not de-interlacing at all.. in fact, I am intentionally taking two fields and interlacing them :)
[2:20] <linuxstb> Ah, I remember reading that thread. Was that really back in August?
[2:20] <Matt_O> I wrote a shader to do that (I am pretty proud of that)
[2:20] * MrOpposite (~MrOpposit@unaffiliated/mropposite) has joined #raspberrypi
[2:20] <Matt_O> I was going to remove that part
[2:20] <linuxstb> So your Pi is outputting in an interlaced video mode?
[2:20] <Matt_O> since I figure it would confuse people.. "Why is he trying to interlace two textures??"
[2:20] <Matt_O> yes.. tv-out
[2:20] <Matt_O> ntsc
[2:21] <linuxstb> You mean the composite output?
[2:21] <Matt_O> yes
[2:21] <Matt_O> best feature of the pi :)
[2:21] <linuxstb> OK, I've never tried that. I'm HDMI only.
[2:21] <Matt_O> I hope they don't remove it in a future rev

[2:21] <[Saint]> it can make LCD setup *sooooo* easy.
[2:21] <[Saint]> power, plug, boom...LCD.
[2:22] <Matt_O> ok I will hopefully release this code this week
[2:22] <[Saint]> Those cheap backing/reverse cameras with composite input are awesome.
[2:22] <Matt_O> my previous attempt I was getting 62 FPS
[2:22] <linuxstb> Matt_O: I'm guessing that interlacing code would work with HDMI as well?
[2:22] <Matt_O> so to go from 62 FPS to 100 FPS is a huge boost
[2:22] <Matt_O> linuxstb, sure it would
[2:22] <Matt_O> it's GLES2 so it is abstract
[2:22] <[Saint]> errr...why did I say cameras. LCDs, even.
[2:23] <[Saint]> I got a bunch of 7" displays from the NZ equivalent of eBay - worked out to about $15ea
[2:23] <linuxstb> Maybe that would solve my problem. I want to be able to output 1080i video in a 1080i HDMI mode, with the fields synced correctly. The GPU doesn't get it right.
[2:23] <Matt_O> oh really
[2:24] <[Saint]> linuxstb: that seems like something Broadcomm might want to know about...
[2:24] * enque (~enque@ip70-160-27-9.hr.hr.cox.net) has joined #raspberrypi
[2:24] <Matt_O> I just update as fast as possible (with wait4vsync mode enabled) and it "just works"
[2:24] <Matt_O> as long as I update every other field every render
[2:24] <linuxstb> [Saint]: They do, or at least, Dom does - http://www.raspberrypi.org/phpBB3/viewtopic.php?f=70&t=33534
[2:25] <[Saint]> AHa.
[2:25] <Matt_O> so if your HDMI is like 60 hz, you'd be rendering 30 fps interlaced video

[2:48] <chithead> first hit on google http://www.raspberrypi.org/phpBB3//viewtopic.php?f=53&t=41667
[2:48] <bity> does anyone think a headless rbpi like web/file sever for ~$30 would be interesting?
[2:49] <[Saint]> its not "openjdk*"
[2:49] <devslash> thats what i use it for
[2:49] <bity> devslash, web/file?
[2:49] <[Saint]> its "openjdk-*-j**"
[2:49] <devslash> media and mail server
[2:49] <devslash> works great
[2:49] <[Saint]> so you'd want "openjdk-6-jre"

[2:51] <hellllp> hey question, if i wanted to run the pi in as small a space as possible, could i unsolder the rca video and audio out plugs and just remove them with no ill effects?
[2:51] <hellllp> i dont use them
[2:51] <bity> but even at 30, it's too close to the pi, it'd need to be like $20 or less
[2:51] <johntramp> hellllp: yeah that should be fine
[2:52] <chithead> file server is possible with any openwrt router that has a usb port
[2:53] <linuxstb> hellllp: See here - http://freneticrapport.blogspot.com.es/2013/02/more-raspberry-pi-power-saving-part-3.html (and the previous parts) for some Pi-stripping advice
[2:54] <bity> i've see simliar devices to what i want to make for like $100, but i want to see a cheap like deaddrop type hub
[2:54] <devslash> chithead: that command doesn't work because of missing dependencies
[2:54] <chithead> devslash: that is why I said you need to download to the pacman directory
[2:55] <devslash> but it fails
[2:57] <chithead> then you need to install the dependencies first. #archlinux-arm may have more advice

[6:13] <hydroxygen> several ..earthquake, youtube, others
[6:13] <fu3l> thanks il be ordering my pi now :)
[6:14] <hydroxygen> the earthquake checks usgs every 15miutes and reports any quakes over mag1
[6:14] <[Saint]> I just scrape geonet's records for that ;)

[6:57] <x29a> devslash: i dont mean to be rude, but if you stick to a distro for "likes", it might seem you know your way round. otherwise, there is always google
[6:59] <x29a> raspbian/debian/ubuntu can also be driven without GUI, just sayin. id rather go for a distro because of recent packages, packages from source, driver support, etc.
[6:59] <devslash> well arch also has recent packages
[6:59] <x29a> mint vs. ubuntu, debian vs. gentoo, etc...
[6:59] <devslash> it happens to be the distro i am most comfortable using
[6:59] <x29a> ok thats cool
[6:59] <SixtyFold> if youre most comfortable with arch, i cant imagine how you could be uncomfy with any other one, just saying
[6:59] <SixtyFold> hehe

[9:20] <[Saint]> It mentions no such driver.
[9:20] <[Saint]> I think you mean governor.
[9:21] <[Saint]> and, yes, performance is quite possibly one of the silliest governors there is. You may as well just disable scaling.
[9:21] <[Saint]> that's all its doing.
[9:22] <Darkwell> yeah
[9:22] <Darkwell> dont want to scale down speed
[9:23] <[Saint]> For what reason? There's very little point in having the CPU at max when idle.

[9:30] <nid0> a case could be made that disabling cpu scaling in favour of a static maximum overclock when an effective cpu scaling is present is a bit stupid, yes

[9:31] <gordonDrogon> Hm. typings a bit out there.
[9:31] <xcadaverx> gordonDrogon: Hey, i've noticed you are really knowledgable on the forums regarding GPIO things. I was just wondering if you've had any experience with Atlas-Scientific.com products?
[9:31] <[Saint]> Morning. Master General Gordon Pi.
[9:31] <Darkwell> wait a min, did i mention overclokcing ?
[9:31] <Darkwell> od do you define idle and having cpu at max rate as overclock ?
[9:31] <gordonDrogon> xcadaverx, never heard of them I'm afraid.

[9:32] <xcadaverx> Alright, thanks anyways
[9:32] <[Saint]> Darkwell: well, if you're not overclocking...why use performance?
[9:32] <[Saint]> it will be min/max 700 anyway unless I'm broken today.
[9:32] <nid0> you asked about the performance governer, that implies you want the cpu overclocked to its maximum
[9:32] <gordonDrogon> xcadaverx, they look somewhat expensive for hobby use...
[9:32] <nid0> if you just want the system to use stock clock and not scale it down, you dont need to use any governer or make any changes
[9:33] <Darkwell> I DONT WANT TO DOWNSCALE THE CPU THATS ALL
[9:33] <[Saint]> welcome to ~10 minutes ago :)
[9:33] <Darkwell> sorry for caps
[9:33] <xcadaverx> gordonDrogon: I've got the EC and PH kit. I've hooked them up and the PH is sending me back readings fine. The EC meter seems to be freezing using the same code though, super odd!
[9:33] <[Saint]> And, it won't. If you don't change anything.
[9:33] <[Saint]> Don't overclock? It won't downscale. Clear?
[9:33] <Darkwell> the on demand governor does downscalle afaik
[9:34] <nid0> so dont enable it
[9:34] <Darkwell> just to test things :
[9:34] <Darkwell> try ti run iptables and then have smoe rules
[9:34] <Darkwell> and add ipset to it
[9:34] <Darkwell> and make it filter traffik
[9:35] <[Saint]> "The latest kernel has a cpufreq kernel driver with the "ondemand" governor enabled by default. It has no effect if you have no overclock settings."
[9:35] <[Saint]> clear as day.
[9:35] <Darkwell> myt prediction is that you will notice differences depending oif you ahve cpy freq scaling on or off
[9:35] <[Saint]> ^
[9:35] <gordonDrogon> xcadaverx, what's the "EC" one?
[9:35] <xcadaverx> electrical conductivity.
[9:36] <xcadaverx> it reads the dissolved solids in water. useful for feeding fish. :)

[9:37] <[Saint]> Darkwell: just to be absolutely crytal clear, carry on what you're doing - and you effectively *are* using the performance governor. Overclock, and things change.
[9:37] <gordonDrogon> xcadaverx, did you get their interface board too?
[9:37] <[Saint]> So, no, unless you overclock any difference you notice will be observational bias.
[9:38] <[Saint]> It doesn't matter what the governor is set to if you're not overclocked, as scaling isn't used at all <-- slightly clearler
[9:39] <[Saint]> ler? ...bah! :)
[9:39] <xcadaverx> gordonDrogon: The serial mux?
[9:39] <gordonDrogon> xcadaverx, https://www.atlas-scientific.com/product_pages/embedded/ec.html
[9:40] <xcadaverx> i did buy that circuit
[9:40] <gordonDrogon> looks like you need that to talk to the sensor then to talk back to the host.
[9:40] <gordonDrogon> that has a PIC microcontroller on it, so I guess it does and wibbly wobbly stuff on the sensor and presents serial..
[9:40] <gordonDrogon> maybe its that which is the problem, but who knows...

[11:04] <Darkwell> perhaps an array of capacitators ?
[11:04] <BurtyB> at ~4.1A isn't likely to hit max charge current on a 100A battery - but iirc you're not supposed to trickle charge SLA so you might want to look at that too

[11:09] <ShorTie> looking at the ds1102e
[11:10] <gordonDrogon> depends on the size of the panel...
[11:10] <shiftplusone> I have a DS1052E hacked to 100MHz.

[11:11] <ShorTie> i just need it to check logic pulses to and from this ultra sonic board
[11:11] <shiftplusone> ShorTie, I am quite happy with it. More than good enough for my needs. The only problem is some of the knobs cracked. They still hold fine, but it's a known problem.

[11:17] <ShorTie> 400 bucks
[11:18] <shiftplusone> Makes sense, since it's identical hardware
[11:18] <shiftplusone> Though I'd go for the DS1102E obviously, since I am not sure if that hack still works.

[14:00] <shiftplusone> steve_rox, by what standard is that hot? O_o
[14:01] <nid0> 1) thats not hot and 2) that temp is being caused by other heat sources, undoubtedly

[14:02] <shiftplusone> That's the temperature inside the chip. It's not going to heat the air around it much at all. Correct me if you have done tests and I am wrong.

[14:03] <[Saint]> very, very slightly.
[14:03] <steve_rox> what would you potentialy use to protect aggenst over voltage?
[14:03] <shiftplusone> The pi PCB maybe, not whatever else you have in the box.

[14:04] <Triffid_Hunter> steve_rox: for reference, the rpi's SoC disables your overclock settings at 85c.. every IC I've ever looked at is rated to 125c, many will handle 150
[14:04] <[Saint]> steve_rox: well, how big is the project box roughly?
[14:04] <steve_rox> ah thanks
[14:04] <Triffid_Hunter> steve_rox: crowbar and a polyfuse
[14:05] <nid0> the pi has a polyfuse protecting the usb power input
[14:05] <Triffid_Hunter> steve_rox: crowbar = zener diode + SCR

[15:25] <dash00> Hi, I'm trying to connect PIR sensor to Raspi. Sensor has it's own power supply (9V battery). The switch is closed when it detects some move. On tester it works on 3.3v with no problem. But I'm not able to set it up on Raspi, I've used gpio3 for out and gpio4 for in, so when the switch is closed, I should have same value on gpio4 as on gpio3 (hope so). Some idea guys?
[15:26] <SpeedEvil> Do you have a datasheet for the sensor?
[15:26] <SpeedEvil> Is the switch just a relay?
[15:26] <gordonDrogon> yea, datasheet- sounds suspicious ...
[15:26] <dash00> I'll find the datasheet gimme sec SpeedEvil
[15:26] <SpeedEvil> If it is - then connect one side to 3.3V, the other to the GPIO pin (through a 1K resistor in case the pin gets set to otuput) and you'red one
[15:27] <gordonDrogon> maybe an open collector or relay output... ?

[15:43] <IT_Sean> what is this 'work' thing of which you speak?
[15:44] <dash00> http://www.raspberrypi-spy.co.uk/wp-content/uploads/2012/09/Raspberry-Pi-GPIO-Layout-Revision-2.png So one wire to pin6 - gnd and second to gpio3, than pull-up gpio3 right?
[15:44] <dash00> work, hmmm some server stuff, we have floods here
[15:44] <IT_Sean> floods & servers do not mix.
[15:45] <dash00> I know
[15:45] <IT_Sean> I am painfully aware that floods and servers do not mix.
[15:45] <gordonDrogon> dash00, http://wiringpi.com/pins/ are you using the physical pin numbers here?

[16:08] <gordonDrogon> ok
[16:10] <gordonDrogon> you might want to consider a 220Ω resistor on the gpio input pin, but it's not really needed - only to protect you from yourself accidentally making the pin an output and writing it high while the sensor triggers - which would short it to 0v and potentially burn the pin out... however I don't do that myself, personally...

[16:15] <perdouille> Hi
[16:16] <perdouille> Got a question: I have a 2nd gen Raspberry (with 512 mb of ram). Can I back-power it without risks ?
[16:16] <nid0> yes
[16:17] <IT_Sean> everything has risks.
[16:17] <dash00> thanks for advice gordonDrogon, when I'll have all work done, I'll write some short article about it. I've here also the kinect =)
[16:17] <IT_Sean> It is, however, relativly safe to do so.

[16:18] <perdouille> I want to power it with the micro usb, but when I connect it to the HUB (for my HDD), It is automatically back powered using USB
[16:18] <gordonDrogon> the risk is that someone on the Pi will short, or another thing you plugin will short, and the power supply feeding it will be of sufficient capacity to cause the PCB tracks on the Pi motherboard to overheat, etc.
[16:18] <gordonDrogon> s/someone/sonething/
[16:19] <perdouille> I don't want it to burn :D
[16:19] <gordonDrogon> it shouldn't be automatically back-powered - that the hub not doing the right thing - sadly most hub's don't do the right thing.
[16:20] <perdouille> It's a Heden HUB, so it don't do the right thing ^^
[16:20] <IT_Sean> Hubs are not supposed to backpower. Sadly, most hubs are a bit crap.

[20:13] <zproc> ok googled, nevermind my question [Saint]
[20:14] <[Saint]> Just replace the contents of the boot partition with <known_good_source>. There's a few ways you can do that, many find it easier to just copy/paste seeing as how its FAT and permissions don't matter.
[20:14] <[Saint]> be it from a backup, an expanded image, or the firmware repo in raspberrypi's github.
[20:15] <zproc> ok thanks, i'm gonna try to copy the boot partition from another sdcard
[20:15] <[Saint]> If it saves having to backup user data and do a full reflash, its worth it. If it doesn't, nothing lost but a few minutes.

[21:11] <JakeSays> benedikt: iirc raspian.org is the people behind the raspian release, and now that it is an 'official' distro it is distributed through raspberrypi.org
[21:11] <ParkerR> Arch really isn't "closer to the kernel" It's just a more minimal system with the aim of being consistently fast
[21:12] <benedikt> ParkerR: debian takes a lot of own decisions, e.g. "the debian way", while arch tends to follow upstream more.
[21:13] <bts__> but definitely Arch is not as 'close to kernel' as Gentoo - no neccessity of compiling, the main advantage is rather simplicity / minimality mentioned

[22:05] <benedikt> messerting: you can't change it. thats the whole part of the ssl/ca system
[22:05] <benedikt> you have to create a new one if you want the domain name to match
[22:05] <benedikt> but since it is self-signed, you can just choose to trust the cert if you can't be bothered with making a new one
[22:06] <benedikt> cryptographically speaking, whether or not the domain name matches is irrelevant.
[22:06] <messerting> benedikt: ok, thanks. Well, my cellphone seems to require a match on server name for self signed certificate for caldav

[23:11] <ozzzy> mine's made in china [shrug]
[23:11] <[Saint]> Even if to you, it "seems hot", it almost certainly isn't...if it still powers on.
[23:11] <plugwash> gonzoflip, in what way is it different

[23:13] * evilsk4ter (~evilsk4te@187.60.66.11) Quit (Remote host closed the connection)
[23:13] <evanjfraser> class 10 means that it can sustain 10MB/s writes IIRC
[23:14] <Phosie> Can never have too many SD cards
[23:14] <evanjfraser> Phosie: +1
[23:14] <[Saint]> or above, seeing as there's no higher class rating. :)
[23:14] <SpeedEvil> [Saint]: Get a 'SpinalTap' card - they go to 11.
[23:15] <Phosie> ha!
[23:15] <SpeedEvil> Can anyone elaborate on the camera driver. Is the driver a blob loaded on the CPU that only supports one camera, or is it a generic CSI interface?
[23:15] <[Saint]> It basically depends on how fast you want to be able to DD an image. Class 4 is "ok" for the OS itself, much faster won't make a notable difference unless you are frequently moving around large files on the disc.
[23:15] * DexterLB (~dex@77-85-28-193.btc-net.bg) has joined #raspberrypi
[23:15] <SpeedEvil> You basically normally only care about the small block read/write speed.
[23:15] * [Saint] nods
[23:15] <SpeedEvil> Which is not specified on any card whatsoever.
[23:15] <jambey> yeah a trancend class 10 is about the same price as a sandisk class 4
[23:15] * tanuva (~tanuva@dslb-178-007-147-104.pools.arcor-ip.net) Quit (Quit: Leaving.)
[23:16] <SpeedEvil> And may be slower on a class 10 that a class 1.
[23:16] <[Saint]> sdcards certainly are one thing where you want to spend the extra to get a trusted brand from a known good distributor.
[23:16] <[Saint]> there's just so much fake trash out there.
[23:17] <SpeedEvil> I'm not saying slow=fake.
[23:17] <evanjfraser> I haven't looked, but reviews with published benchmarks would be handy. Are there any?
[23:17] <SpeedEvil> Just that small block performance is essentially not specified.
[23:17] <[Saint]> One of my personal favourites was a 4MB sdcard hacked up to represent itself as a 16GB disc. :)
[23:17] <[Saint]> That was a fun purchase.
[23:17] <SpeedEvil> Ow.
[23:17] <evanjfraser> <[Saint]> I've seen that happen too
[23:18] <[Saint]> It usually happens in USB thumbdrives.
[23:18] <[Saint]> from my experience.
[23:18] <NullMoogleCable> ok just for the heck of it, i overclocked the pi, and magically it works now...
[23:18] <[Saint]> Seeing a hacked up 4MB sdcard made me giggle quite loud.
[23:18] <[Saint]> NullMoogleCable: it almost certainly won't for long. ;)
[23:19] <NullMoogleCable> :-p i got the dicast copper heatsinks for cpu ethernet and power :D and a small 5v fan... this aint overheating
[23:20] <[Saint]> it wouldn't have done so before.
[23:20] <[Saint]> Spend all the needless cash you want, though.
[23:20] <[Saint]> I only got them reliably shutting down due to overheating after pushing 1.2GHz.
[23:21] <[Saint]> which is universally considered "A Very Bad Idea"
[23:21] <Phosie> Impressive.
[23:21] <[Saint]> 60C will burn you, and you'll think "Ohhh, damn, that's hot"...but, its only hot, *for you*. Heck, ~40C is too warm for a human to hold on to for too long.
[23:22] <Phosie> *Almost* the same as my netbook (1.66)
[23:22] <[Saint]> But an SoC and the other components on the board literally laugh at this.
[23:22] <taza> So THAT'S why my Pi is always eerily giggling
[23:22] <[Saint]> Some of the components on the board likely exceed ~120C
[23:23] <[Saint]> most seem to be in that range.
[23:23] <[Saint]> The SoC just cuts out at 85C for a guaranteed safety margin.
[23:24] <SpeedEvil> [Saint]: 40C is a hot bath temp.
[23:24] <[Saint]> If you stay in there too long, at that sustained temp, you'll feel it alright.
[23:24] <chod> anyone looked at souliss for arduino ?
[23:24] <SpeedEvil> Well, yes, but you can hold onto a 40C object forever.
[23:25] <chod> just a raspberry pi could interface to it well
[23:25] <SpeedEvil> And it's below the maximum skin contact temperature for theraputic heating pads.
[23:26] <[Saint]> Maybe I'm cold blooded. ;) I wouldn't find ~40C too comfortable to hold on to for a sustained period.
[23:27] <[Saint]> The max temp at the tap here is 45C

[23:34] <ozzzy> I have one made in UK and one made in China
[23:34] <ozzzy> thought they were both chinese
[23:34] <[Saint]> gonzoflip: looks fine to me.
[23:35] <gonzoflip> $44 from Speed Of Light Distributors, not whatever vendor I said earlier.
[23:35] <[Saint]> Why does everyone seem to freak at "Made in China". Really?
[23:36] <plugwash> notice how the raspberry pi foundation are constantly praising sony's quality?

[23:37] <plugwash> think what they must be comparing sony's quality too
[23:37] <gonzoflip> Saint: because I have bought 4 already before this and then my fifth came from china, all the other ones were made in the UK. It kind of caught me off guard
[23:37] <ozzzy> $35 from Newark/Element 14
[23:38] <[Saint]> gonzoflip: a tiny bit of googling would've left any doubt at the door.
[23:38] <[Saint]> or, should've.
