[0:00] <willmore> chod, I'd say that the answer is more nuanced than Ryccardo mentions. Yes, the ethernet port is connected to the CPU in the same way on both boards, but the CPU was a limit on the rpi. On the pi2 it's not:

[0:01] <Ryccardo> peeps[work]: depends on devices, obviously... but unlikely
[0:01] <peeps[work]> so why put 4 ports on it
[0:01] <ShorTie> yes, with a 2.5amp supply and the current limit hack
[0:01] <Ryccardo> SpeakerToMeat: Sonny_Jim: in debian the group is "sudo" by default
[0:01] <peeps[work]> howmuch power caqn be supplied to usb without any hack?
[0:02] <peeps[work]> ShorTie, what is this hack?
[0:02] <ShorTie> 600ma total

[0:03] <SpeakerToMeat> Sonny_Jim: there's no sudo app, plus I have only root, no user login
[0:04] <ShorTie> don't need no sudo, lol.
[0:04] <Ryccardo> SpeakerToMeat: well, you can install it... :)
[0:04] <ShorTie> root is where it's at

[0:05] <Ryccardo> I prefer sudo because of the "timestamp_timeout=2500" and "insults" options ;)
[0:06] <SpeakerToMeat> I have a custom kernel build, is there an easy way to find if a new firmware will require a newer kernel?
[0:06] <ShorTie> what bootloader are you using ??
[0:07] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) has joined #raspberrypi
[0:08] <ShorTie> the foundations bootloader/firmware is kernel depenant

[0:10] * tombrough (~tom@cpc3-newt3-0-0-cust165.19-3.cable.virginm.net) has left #raspberrypi
[0:10] <SpeakerToMeat> So if I update to main, I better update my kernel then
[0:10] <SpeakerToMeat> Seems lattest branch is 3.18.y
[0:10] <ShorTie> don't know what cha mean by 'main'

[0:13] <ShorTie> raspberrypi-bootloader brings in the lastest kernel, raspberrypi-bootloader-nokernel has no kernel and you have to install according to the pi it is being used on
[0:15] <SpeakerToMeat> Interesting, lattest firmware worked with my 3.12 build. But I'll switch to 3.18 soon

[1:03] <willmore> niston oXo Bilby
[1:04] <willmore> Peetz0r, I'm guessing you ran out of memory.
[1:04] <willmore> Try it on a bigger machine.
[1:04] <willmore> 512mB with some for graphics and camera doesn't leave a ton for large image manipulation.
[1:05] * willmore doesn't have a camera or he'd try.
[1:06] <methuzla> Peetz0r I think it's the -t parameter that's throwing you off

[1:48] <willmore> Does the camera on the pi do black level compensation on long exposures? It may be doing it per exposure--which is one of the reasons to use exposure stacking--you can avoid that overhead.

[1:59] <waveform> willmore, you'd have to ask the firmware devs for a definite answer but I vaguely recall from some forum thread that it does do per-exposure compensation
[1:59] <HtheB> does anyone has some experience with PiTFT?
[1:59] <HtheB> I've tried to get mine to work, but no dice
[2:00] * mattwj2002 (4b49ba0e@wikisource/pdpc.active.mattwj2002) has joined #raspberrypi
[2:00] <mattwj2002> hi all
[2:00] <mattwj2002> I just got a raspberry pi 2!
[2:00] <mattwj2002> :D
[2:00] <mattwj2002> I had a few questions if anyone is available.....
[2:00] <mattwj2002> do any of the images work for the 2?
[2:00] <mattwj2002> *all not any
[2:00] <ozzzy> get a pi2 image
[2:01] <willmore> mattwj2002, Any of them from Feb or later is what I was told.
[2:01] <mattwj2002> ozzzy: it has to be a pi2 image?
[2:01] <mattwj2002> okay thanks
[2:01] <ozzzy> if you want to be SURE that it'll go well
[2:01] <willmore> Nothing is SURE. :)
[2:02] <mattwj2002> oh I see where it says pi 1 or 2
[2:02] <mattwj2002> thanks!
[2:02] <mattwj2002> anyone else have pi2?
[2:02] * willmore just got his.
[2:02] <ozzzy> yep... I bought 2
[2:02] <willmore> niston, wake up!
[2:02] * HtheB has pi1B rev1
[2:03] <willmore> HtheB, I've only used generic serial TFT displays with the rpi.
[2:03] <mattwj2002> also how stable is Snappy Ubuntu Core and what is the deal with Windows 10 for Pi2?
[2:03] <HtheB> willmore: I'm using a generic one too now
[2:03] <ozzzy> Win10 is still vapourware and I run raspbian
[2:03] <willmore> mattwj2002, the win10 for pi2 is just a headless IoT device building kit.
[2:03] <HtheB> but it gives me white screen :(
[2:03] <mattwj2002> headless? no gui!
[2:04] <mattwj2002> :|
[2:04] <willmore> HtheB, it doesn't like you. Did you ask nicely.
[2:04] <willmore> mattwj2002, yeah, it's not a desktop version of windows.
[2:04] <HtheB> believe me, I asked very very nicely :D
[2:04] <mattwj2002> well F Microsoft then :)
[2:04] <mattwj2002> sorry if F is too close to a swear word
[2:04] <ozzzy> I'll install it
[2:04] <mattwj2002> I know there are probably kids in here
[2:04] <willmore> It's for embedded IoT applications. So, basically a publicity stunt as you'd have to be daft to use MS software for something like that.
[2:05] <willmore> If they know what 'F' stands for, then they already know what 'F' stands for...
[2:05] <mattwj2002> good point :P
[2:05] <mattwj2002> well I am going ubuntu
[2:06] <mattwj2002> alpha or no alpha it sounds interesting
[2:06] <willmore> HtheB, hard to debug wiring over the internet.
[2:06] <ozzzy> this Pi isn't doing anything but increasing the entropy of the universe.... so Win10 can do that just as well as anything else
[2:06] <HtheB> :D
[2:06] <HtheB> I have this one: http://www.ebay.com/itm/111438206242
[2:06] <willmore> I've used my cheap displays on two different Pis and an odroid-C1. Didn't have any issues and I had to guess a lot at the wiring.
[2:06] <Cessna1090> anyone happen to have expierence using a potentiostat with the RPi?
[2:06] * OffensiveUser (~Offensive@5ED3D4A2.cm-7-4d.dynamic.ziggo.nl) Quit (Quit: Leaving)
[2:07] * ozzzy wonders what a potentiostat is
[2:07] <mattwj2002> one has to ask.....
[2:07] <willmore> HtheB, that's pretty.
[2:07] <mattwj2002> does entropy in the whole universe really matter or is just our know solar system enough to worry about :P
[2:07] <HtheB> yes, pretty white :D
[2:07] <HtheB> shows only white :(
[2:07] <willmore> I'm guessing it's an interesting mistranslation of 'variable resistor'.
[2:08] <mattwj2002> besides ....
[2:08] <ozzzy> mattwj2002, eventually it matters
[2:08] <willmore> HtheB, do you know it works? If the controller is good, the display should be *black*, not white. I had one DOA that was white.
[2:08] <mattwj2002> the Milk Way is combining with the andromeda galaxy in a few billion years anyways
[2:08] <mattwj2002> doesn't matter to me I won't be here!
[2:08] <mattwj2002> :)
[2:08] <HtheB> willmore: how can I check if mine is a DOA?
[2:09] <HtheB> because it looks like it :/

[2:09] <mattwj2002> so yeah
[2:09] <willmore> HtheB, I do not know. I had multiple displays to compare and the broken one was clearly different than the others.
[2:10] <Cessna1090> nadia drake is a hottie.
[2:10] <HtheB> and I was happy that mine came in only 7 days
[2:10] <HtheB> (never had such a fast delivery)
[2:10] <mattwj2002> I ordered mine on Friday...it arrived today...I could have had it next day if I wanted
[2:11] <mattwj2002> I bought a whole kit though...not just a rpi and I have Amazon Prime :)
[2:11] <ozzzy> Cessna1090, I can't see the usefulness of that
[2:11] <willmore> Cessna1090, that's an interesting device and very, very specific to a certain use.
[2:12] * willmore isn't sure what Nadia Drake's supposed hotness has to do with anything.
[2:12] * ozzzy isn't sure who Nadia Drake is
[2:12] <willmore> You're not going to use the potentiostat on her?
[2:13] <willmore> That, too, ozzzy.
[2:13] <mattwj2002> yeah willmore that would just be wrong
[2:13] <mattwj2002> :P
[2:14] <mattwj2002> I'll tell you a nice thing about a the pi2
[2:14] <mattwj2002> more usb ports than my old pi b!

[2:15] <Cessna1090> she wrote the article mentioned earlier..i digress
[2:15] <mattwj2002> ozzzy: how are you measuring that?
[2:15] <mattwj2002> I have done something similar with arduino
[2:15] <ozzzy> it's just showing the cpu temp
[2:16] <mattwj2002> oh!
[2:16] <mattwj2002> I thought that was room temp
[2:16] <ozzzy> nope... but I have a temperature probe that I'll add when my 3.5mm stereo jacks come in

[2:49] <mattwj2002> right
[2:49] <willmore>
[2:50] <mattwj2002> but if you try to connect to it via ssh it won't work ... you can only connect to it via ip address out of the box
[2:50] <mattwj2002> :)
[2:50] <mattwj2002> or change the hostname
[2:50] <willmore> No other box will care what it thinks its hostname is.

[2:52] <willmore> Works here, mattwj2002.
[2:52] <Tenkawa> yeah its goofy about that
[2:52] <willmore> Sure you are running sshd locally?
[2:52] <Tenkawa> look in /etc/ssh/sshd_config
[2:53] <Tenkawa> for the listen lines
[2:53] <mattwj2002> I am not running it locally but my pi has it enabled by default
[2:53] * leichtgewicht (~leichtgew@p14157-ipngn100101osakakita.osaka.ocn.ne.jp) has joined #raspberrypi
[2:53] <willmore> Then put in the IP address of the pi, not localhost.
[2:53] <mattwj2002> just saying a hostname other than localhost might be a good idea
[2:53] <Tenkawa> mattwj2002: all machines have a loopback reference to itself as localhost
[2:54] <mattwj2002> localhost causes unnecessary confusion for noobs
[2:54] <mattwj2002> right.....
[2:54] <willmore> It's necessary confusion.
[2:54] <mattwj2002> but won't a hostname like ubuntu{part of the mac address} or something similar be more logical?
[2:54] <mattwj2002> or just a standard one like snappy or something?
[2:55] <Tenkawa> mattwj2002: that name will be for its hostname and ip address of the interface
[2:55] <Tenkawa> ethernet
[2:55] <willmore> I put a hostname field in my DHCP server and the boxes pick it up automatically.
[2:55] <mattwj2002> willmore: just trying to give my opinion not anything else
[2:55] <mattwj2002> :)
[2:55] <Tenkawa> is for the loopback interface
[2:55] <Tenkawa> ie localhost
[2:55] <Tenkawa> its a tcp/ip standard i think still
[2:55] <mattwj2002> right
[2:56] <mattwj2002> yeah I think that is right
[2:56] <mattwj2002> I have seen with rpi1 images
[2:56] <Tenkawa> you would put the hostname on the "real" ip
[2:56] <mattwj2002> normally they have a name like octopi
[2:56] <mattwj2002> or something else
[2:56] <Tenkawa> right.. however those would have "routeable" ips
[2:57] <mattwj2002> snappy doesn't have a routable ip?
[2:57] <Tenkawa> sure.
[2:57] <Tenkawa> you can change the hostname by editing /etc/hostname
[2:58] <mattwj2002> yup it is no problem for me
[2:58] <mattwj2002> I was just trying to give my opinion to aid in future versions of the snappy ubuntu image!

[4:00] <ozzzy> that's not where the money is
[4:01] <ryankarason> understandable
[4:01] <ozzzy> and then there's focuser control, filter wheel control, blah blah
[4:01] <ozzzy> yeah... totally
[4:01] <ryankarason> interesting.
[4:01] <ozzzy> I love linux... but if I have to boot a VM to get anything done why am I not in the VM'd OS to start with
[4:01] <ryankarason> see, i am particularly interested in getting linux running on a camera so i can write all my own software=P
[4:01] <ryankarason> ozzzy: very understandle
[4:01] <ryankarason> see, i run pure linux and 0 vms
[4:02] <ozzzy> I did that for years =)
[4:02] <ryankarason> there isn't a single windows or mac or solaris or w/e application that i am dependant on
[4:02] <ozzzy> even have a linux app that's still being downloade (dunno why)

[4:05] <ryankarason> i am curious what the minimal system you would need, such taht you could do it all "in the field"
[4:05] <ozzzy> I can do it with a 2-core Atom, 2G ram and a 60G ssd

[4:11] <ozzzy> anyway... we got a box of those boards and a bagful of 60G ssds that were going out in the garbage
[4:11] <ozzzy> put together some nice little boxen
[4:12] <ryankarason> very cool
[4:12] <ozzzy> that one has 6 USB ports, 2 gigabit ethernet ports, VGA, rs232 and 802.11n
[4:12] <ryankarason> i recently got a neat little "box" though... it isn't a box at all
[4:12] <ozzzy> runs win7-64
[4:12] <ryankarason> its essentially rpi spec, but much smaller
[4:12] <ozzzy> ahhh... that sounds interesting
[4:12] <ozzzy> which board

[4:14] <ozzzy> now that is kinda kewl

[7:19] <Stephini_> but ultimatly the answer to weather it would harm the pi if say i ran my 5v pin to a ground pin and just left it there all day is that it wouldn't harm the board...just waste energy?
[7:19] * toomin (~HomoSapie@unaffiliated/toomin) Quit (Ping timeout: 244 seconds)
[7:21] <ShorTie> not gonna say it will or will not hurt the pi because sortta like hard to tell, but what it will do is kill what ever the 5v is coming from
[7:21] <ShorTie> it is called a short, and shorts are bad bad bad!!!!
[7:22] <Xark> "best case" a fuse or other protection method will trigger...worst case is worse. :)
[7:22] <ShorTie> up in smoke
[7:23] <Stephini_> ultimatly what i plan to do is wire 2 nes controllers (all 4 of mine require 5v apparently) i know i need to downstep the data lines to 3.3v i'm just looking for confirmation that the ground doesn't also need to be downstepped.
[7:24] <ShorTie> ground is 0v, ie: no potential, so there is no 'downstepping' it
[7:24] <Datalink> Stephini_, ground is generally common in digital circuits, the 5V pins or 3.3V pins are those voltages above ground potential
[7:24] * chunkyhead (~kromo@unaffiliated/chunkyhead) has left #raspberrypi
[7:25] <Datalink> Stephini_, in short, the NES controller's ground and the Pi's ground can be wired directly together, in most digital cases 'ground' or 'gnd' means it can be among the common potential, it gets a bit different in analog but in digital ground is ground
[7:26] <Stephini_> ShorTie, you keep saying that as if it's a universal truth which makes me wonder if i'm just really misunderstanding electricity but from what i understood you put current in through xV it runs through your circuit if it does things it exits through a data line but if it misses all those data lines it runs through the ground pin. so the line coming into the ground pin would have a current unless i really missunderstand
[7:26] <Stephini_> electricity.
[7:27] <ShorTie> you do not 'put' current in
[7:27] <ShorTie> you apply a voltage
[7:27] <ShorTie> the resistance of a circuit will 'draw' a current

[7:29] <ShorTie> you attach a voltage source, that source can supply "up to" X amount of current
[7:29] <Datalink> Stephini_, think of ground as the drain, hydrolic equipment has a reservoir of fluid ready to be pumped to pistons, ground acts similar to this for digital circuits
[7:30] <Datalink> Ground is also often called 'common' because it is the common point of electrical potential for the circuit to offset other parts from

[7:38] <ShorTie> i bag to differ with that
[7:39] <ShorTie> s/bag/beg/ or how ever it is spelt

[7:44] <Datalink> ShorTie, source, sink, drain, have come up in my experience, and yeah, typically they are transistor terms, I've heard them applied elsewhere though
[7:46] <Stephini_> analogies quite often are used to bridge different degrees of understanding. and since water is observable and electricity isn't directly observable if they behave in any way similarly they can be valid ways to convey a concept. i'm not sure if they do but i always (maybe miss)understood that electricity moves like water from one higher point to one lower point at a set rate.

[7:47] <Stephini_> in the case of electricity it moves from a point of high energy to a point of low energy the same way heat does. instead of planetary gravity being the driving force.

[7:50] <ShorTie> yes, the basic concept of many things like water flow, hydraulics, phnematics, electricity are the same can be applied to all
[7:52] <ShorTie> but once you get pass the very basic, you need a more though understanding of individual comments, yes, this thing maybe 'like' that thing
[7:52] <ShorTie> like a flow valve is 'like' a resistor

[12:10] <Triffid_Hunter> SindaFi: changing routing for a specific process is hard work, it would be easier to change routing for specific IP addresses
[12:11] * Tachyon` blinks
[12:11] <SindaFi> Does that involve ip tables - i'm still learning nix so i'm not a pro
[12:12] <Triffid_Hunter> SindaFi: per-process routing involves things that are more complex than iptables
[12:12] <mattwj2002> this is generally referenced as a split tunnel.....which just means one network go through the tunnel everything else aka the Internet use your normal connection
[12:12] <Kryczek_> SindaFi: no need for iptables
[12:12] <Triffid_Hunter> and less widely documented
[12:12] <endiruna> i have bought a old radio on ebay. i am planning to connect the pi to it and later use also the buttons to do stuff. the old owner had changed the speakers. so i have this speaker but do not know the dettails of the speaker. if i connect them to the pi via jack do you think i could destroy the pi?
[12:12] <endiruna> i am worried of the induced current
[12:12] <Triffid_Hunter> endiruna: yes. the pi does not have line input
[12:12] <mattwj2002> but Triffid_Hunter appears way smarter than me so he is my default route!

[12:13] <endiruna> Triffid_Hunter: the pi has a jack so i would immagine a mini amplifier right?

[12:14] <ali1234> the jack is meant for driving line in, or earbuds

[12:15] <SindaFi> Thanks Kryczek_ IP address wise ... is this my local IP (192.169.*.*)
[12:15] <mattwj2002> 169?
[12:15] <mattwj2002> shouldn't that be 168?
[12:15] <mattwj2002> 169 is public and 168 is private
[12:15] <SindaFi> It should, typo :)
[12:15] <Triffid_Hunter> endiruna: unlikely, it's only line level output. if you want to drive a speaker, you'll need an LM386 or similar, and if you want to receive audio you'll need a USB line-in

[12:16] <Kryczek> SindaFi: sorry I am not very familiar with what ZNC is either, I meant the IP address (or hostname in fact) of the IRC server, like irc.freenode.net for here
[12:16] <SindaFi> Plus is it okay to use a domaon of my VPN as the ip is dynamic?
[12:16] <SpeedEvil> Otherwise, you need a different solution
[12:17] <mattwj2002> anyways I need to run
[12:17] <mattwj2002> have good day all

[13:35] <shiftplusone> depends on the individual pi.
[13:35] <shiftplusone> you can read the oscillator frequency value to compare to other pis to get a rough idea
[13:35] <steve_rox> well yea but
[13:35] <shiftplusone> mine one goes to 1050, but won't budge past that.
[13:35] <steve_rox> the rpi1 can be oc to like 1000
[13:35] <steve_rox> ah
[13:36] <steve_rox> was trying to get some kinda base line idea
[13:36] <shiftplusone> it's pretty much the same silicon and process as in the pi 1
[13:36] * janeway (~anonymous@ has joined #raspberrypi
[13:37] <steve_rox> anyone done anything interesting with rpi2?
[13:37] <Xark> steve_rox: Complile stuff without falling asleep in the meantime. :)
[13:37] <steve_rox> hehe
[13:37] <shiftplusone> I could probably describe how they're able to get slightly better clock rates on the pi 2 over pi 1, but the piece of paper it was described to me on was quickly shreded
[13:38] <shiftplusone> so I guess it's sensitive information and I don't want to be shredded too.

[13:40] * Xark has gotten the best results on his macro assembler with g++-4.8 with --mcpu=cortex-a7 -mfpr=neon-vfpv4 -O3 -mthumb (the -mthumb was a mild surprise, but smaller seems to be faster).

[13:41] <Xark> willmore: Yes. Little downside, and good chance of 16-bit ops.
[13:41] <shiftplusone> willmore, what do you mean by memory bound?
[13:41] <willmore> Depends on the code, of course.
[13:41] <willmore> shiftplusone, main memory bandwidth.
[13:41] <shiftplusone> willmore, that has doubled... just waiting for that patch to go to the repos.
[13:41] <willmore> Xark, thumb2 does often give a performance boost is you're I cache constrained.
[13:42] <willmore> shiftplusone, that's good news!
[13:42] <shiftplusone> willmore, it's the same as C1 now, heh. The initial benchmarks were a little worrysome.
[13:42] <Xark> willmore: Yep. Seems about ~%4 faster on my benchmark (huge assembler file).

[14:03] <willmore> Really should specify it in mega-transfers/second to be clear, I guess.

[14:11] <willmore> Okay, that was a worry last night when we were talking.
[14:11] <HtheB> it's not a DOA at least
[14:11] <willmore> Then you just need to see how they're initializing it.
[14:11] <willmore> That shouldn't be hard.
[14:11] * willmore says encouragingly.
[14:11] <HtheB> I'm just reading that RetroPie is using OpenGL

[14:18] <HtheB> MY123: so, just running the install script would solve my problem??

[15:15] <ali1234> okay. well in that case i would knock something together based on wayland and qt5/webkit
[15:15] <designbybeck__> so we just wanted to merge it to a few all kiosks around to give them a new fresh update
[15:15] <designbybeck__> they are running winxp and old hardware

[15:16] <waveform> sounds easy enough - get init to spawn lynx and you're done ;)
[15:16] <shiftplusone> >_<
[15:16] <ali1234> you can make a web browser in about 3 lines of code with Qt. it's so easy that they use it in their demos of QtCreator
[15:16] <ali1234> and wayland has been done
[15:17] <designbybeck__> don't think we have anyone here that does qt5 stuff...but I do think our team should look at it
[15:17] <ali1234> in fact you could do it in QML
[15:17] <ali1234> which is just javascript, so find a web designer and make them learn it
[15:18] <shiftplusone> I'd just use kweb and not bother with any of that.

[15:25] <designbybeck__> like you take out X you dton' have gui

[15:28] <waveform> yup, that's me
[15:28] * kzard (~kzard@ has joined #raspberrypi
[15:29] <waveform> ah, the annotations stuff. Yeah, that was interesting
[15:29] <Hix> could you explain the V2 / V3 thing to me as it seems that you have cured the flicker. I'm getting lost inreferecnes to userland etc etc
[15:29] * oxhak (~OxHaK@unaffiliated/oxhak) Quit (Remote host closed the connection)
[15:29] <Hix> I'm a mech eng so this is going waaaay over my tiny head
[15:29] <Hix> :)
[15:30] <waveform> I can try; the annotation system has been expanded (in capabilities) in the firmware over time. Rather than break all existing code that uses annotations by altering the structure used to configure annotations, 6by9 (the firmware dev responsible) added new structures
[15:30] <waveform> ANNOTATE_V2_T, ANNOTATE_V3_T, etc.
[15:30] * jimvideo (~jimvideo@184-12-233-85.dr01.brny.ca.frontiernet.net) has joined #raspberrypi
[15:30] <waveform> now ... let's see how I can explain this
[15:31] <waveform> underneath, at the firmware level (as I understand it), the annotation code is only using the latest version of the structure (V3). On top of that there's a little shim that converts the older structures into the newer structures as required
[15:31] <ali1234> annotation system puts text on to the picture before encoding it?
[15:32] <waveform> yes
[15:32] <ali1234> okay, this is of interest to me then
[15:32] <Hix> ok, sort of following
[15:32] <waveform> however, when the new firmware with support for V3 annotations was released (#767 or thereabouts), there was a bug in it that caused "get" requests for the V2 structure to fail in interesting ways (basically it came back partially correct, partially garbage)

[15:33] <Hix> what a time to drop out :/
[15:34] <waveform> Hix, no worries - you didn't miss anything
[15:34] <Hix> logs to the rescue :)
[15:34] <waveform> "set" requests worked fine, but "get" requests were broken. 6by9 fixed that up nice and rapidly and released a test firmware (https://github.com/6by9/userland/tree/PR20150310)
[15:34] <Hix> oh
[15:34] <waveform> but I don't think that fix has made it into the official firmwares yet
[15:34] <waveform> oops - that's not the firmware link - hang on

[15:35] * kevin (~keady@wsip-184-183-183-90.dc.dc.cox.net) has joined #raspberrypi
[15:35] <ali1234> waveform: is there a way to say "here is a dispmanx surface, use it as an overlay"?
[15:35] <waveform> okay. So, the situation is that anything using annotate v1 structures works happily in all firmwares but has very limited capabilities (I don't think anything actually uses it)
[15:35] <Hix> ah, so it's a case of put up with it until the foirmware updates?
[15:36] * Datalink (~Datalink@unaffiliated/datalink) Quit (Quit: Datalink offline)
[15:36] <waveform> anything using annotate v2 will be broken on the latest firmware until it updates if and only if it uses get requests with annotations (raspivid/raspistill don't, picamera does, don't know about raspimjpeg and stuff like that)

[15:37] <waveform> the next release of picamera (1.10) will be using annotate v3 but falls back to v2 if the underlying firmware doesn't support it
[15:37] * yeticry (~yeticry@ Quit (Remote host closed the connection)
[15:38] <waveform> ali1234, as far as I know not at the moment. IIRC, 6by9 mentioned he wanted to work on a component like that at some point, but hasn't had the time yet
[15:38] * yeticry (~yeticry@ has joined #raspberrypi
[15:38] <waveform> ali1234, it is certainly possible to have the camera output used as a texture by opengles though, as raspivid can demonstrate by wrapping the preview on a teapot :)
[15:39] <ali1234> waveform: my application is a battery powered vehicle which also has a 3d compass... i want to draw an artificial horizon onto the camera picture before streaming it with raspicam -> gstreamer
[15:39] <Hix> is this the source of the problem in raspimjpeg do you think? https://github.com/silvanmelchior/userland/blob/master/host_applications/linux/apps/raspicam/RaspiMJPEG.c#L416
[15:39] <ali1234> for now though, i can use annotate to just put the heading as text?
[15:40] <waveform> ali1234, ahhh ... hence why you need it before it hits the h264 encoder. I *think* that's impossible at the moment, but I'm happy for one of the firmware devs to correct me
[15:40] <ali1234> right, exactly
[15:40] * Anorion (~Anorion@unaffiliated/saidinunleashed) has joined #raspberrypi
[15:41] <Hix> and if it is waveform do you know if I could modify the raspimjpeg.c file and make it, or is that too simple?
[15:41] <waveform> Hix, well that's certainly using the ANNOTATE_V2_T structure, but I only see a parameter_set call beneath that. I *thought* the bug in the firmware only affected get requests, but I could be wrong

[15:56] <ali1234> my favourite thing about git is you can git log individual files or directories, and it shows only the commits that affect what you specified
[15:56] <ali1234> here is another book about git, it's more focused on teams though: http://cbx33.github.io/gitt/
[15:57] <waveform> Hix, eurgh - tons of conflicts when trying to merge from upstream. Unfortunately I haven't got time to deal with all that, sorry!
[15:57] <ali1234> and it has an internal narrative which isn't my cup of tea but some people like that kind of thing

[16:07] <waveform> Hix, The V2/V3 bit is basically a trivial fix. The issue is that they haven't kept their fork of userland up to date with the upstream (they're 180+ commits behind according to github) so they haven't got the ANNOTATE_V3 structures in their copy of the headers

[17:51] <shiftplusone> okay, just making sure you're not using an ancient img from raspberrypi.org
[17:51] <shiftplusone> what's the crash? pastebin the output?
[17:51] <meLon> Well, those 'ancient' images always worked for me :P
[17:51] <meLon> No crash report, no journal logging, nothing nothing nothing
[17:51] <shiftplusone> so what happens?
[17:52] <meLon> The only difference is that the 'Activity' light on the actual pi stops lighting up
[17:52] <meLon> But the other lights still act normally
[17:52] <meLon> I'll be SSH'd in and doing nothing and it freezes

[17:54] <shiftplusone> If you think you've ruled out all hardware problems and think it's arch that's at fault, you can go to #archlinux-arm... however, you're wrong and they'll tell you something unhelpful and potentially rude.

[17:55] * ShorTie thinkz, and 'you're wrong' is not
[17:56] <McBride36> #archlinux-arm is incredibly rude
[17:56] <shiftplusone> meLon, this is just a hypothesis, but here's what's actually happening... your powers supply and/or cable is bad and resulting in your pi not getting 5v. When the load increases, your connection is dropping out and your pi may even be hanging.
[17:57] * ndrei (~avo@ has joined #raspberrypi
[17:57] <shiftplusone> meLon, if you've seen the red led flicker, that would confirm the problem.
[17:57] <ShorTie> but then why does debian work ok then ??
[17:58] <shiftplusone> perhaps he hasn't loaded the system enough for the problem to occur... if you're dealing with an intermittent problem, you can pick up all kinds of patterns which aren't actually there.
[18:00] <meLon> shiftplusone: Thanks for the suggestion. I'll add 'cables and adapters' to my list of things to switch out when troubleshooting. Starting now :D
[18:00] <shiftplusone> meLon, do you have a multimeter?
[18:00] <meLon> HOWEVER!!! I don't understand how debian could manage this better, resulting in it not crashing

[18:03] <MY123> ozzzy, you can code a JVM in bash
[18:03] <ozzzy> my dvd copying software (which is still downloadable) was mostly BASH with some PERL for a front-end
[18:03] <MY123> ozzzy, if your expectations are low
[18:04] <MY123> (also using a bit of awk and sed)

[18:20] <meLon> I'm hoping, even though it doesn't make a lot of sense to me, that shiftplusone was correct about the voltage. So confused as to how rasbian stayed up all night (8+hr) when this newest archlinux build only lasted (at most) 10m.

[18:24] <shiftplusone> I worked on a thing over the weekend and got it working. I came in on Monday and it no longer worked. Do I then conclude that it doesn't work on Mondays? Or does it indicate that the problem is intermittent? You know what else is intermittent? Hanging when the the voltage is out of spec.
[18:24] <meLon> Is anybody here using archlinux for their pi's?
[18:24] <ShorTie> i'd sortta think 8+ hours of raspbian would like rule that out
[18:25] <McBride36> i used it for a brief period of time
[18:25] <McBride36> but it'd boot up into readonly
[18:25] <meLon> Me too, ShorTie, but without journal giving me *any* information about shutdowns... I'm at a loss
[18:25] <McBride36> and i got tired of that

[18:27] <meLon> FDX solid, LNK is mostly solid, but it's flashing a bit
[18:27] <shiftplusone> almost sounds like an SD issue now... but I'll leave you guys to it.
[18:27] <meLon> 100 is yellow
[18:27] <meLon> I've tried two different SD cards ;_;
[18:27] <McBride36> what class?
[18:28] <meLon> SDHC 8GB and SDHC 8GB (Ultra/30MB/s)
[18:28] <meLon> Both sandisk. Both have run archlinux previously. Both can run rasbian over night.
[18:29] <shiftplusone> hang on... you're talking about the link light.... Is this not a B+ or Pi 2? Is this an old model b?
[18:29] <meLon> I've been trying with 256 and 512 version
[18:29] <meLon> That's why I'm confident it's an archlinux bug
[18:30] <shiftplusone> the memory size doesn't say much, so I'll assume you're talking about model bs
[18:30] <shiftplusone> in which case, the red led doesn't tell you anything.
[18:30] <shiftplusone> so the multimeter is critical here.

[18:31] <meLon> I see TP2 near the audio port.
[18:32] <meLon> I'm having trouble finding TP1
[18:32] <ShorTie> here meLon, these might help, but i don't know if i'd update them http://downloads.raspberrypi.org/arch/images/
[18:32] <meLon> I see P1
[18:32] <meLon> ShorTie: <3
[18:32] <shiftplusone> should be somewhere diagonally across near the other side of the board. I don't remember the exact position

[18:40] <meLon> Just start over
[18:41] <shiftplusone> of=/dev/mmcblk0 is right.... or was the image of a partition?
[18:41] <rinfiyks> oh is it?
[18:41] <shiftplusone> what's the image you used?
[18:41] <rinfiyks> raspbian
[18:41] <shiftplusone> yea, you're fine.
[18:41] <rinfiyks> oh I assumed it was wrong since it wasn't booting
[18:41] <shiftplusone> it's the image of a whole disk, not just a partition.

[18:44] <rinfiyks> I have sd card plugged into my laptop right now
[18:44] <shiftplusone> after dd, partprobe /dev/mmcblk0, fsck /dev/mmcblk0p2

[22:11] <HtheB> I have a 28r screen
[22:11] <methuzla> Warbird: you can't run motors straight from GPIO, you'll need additional hardware (but not necessarily a hat)

[22:13] <Warbird> methuzla, thought so. Thanks for verifying.
[22:13] <OffensiveUser> http://www.adafruit.com/products/381 this one is
[22:13] <methuzla> Warbird: also look at http://www.adafruit.com/products/381

[22:14] <Warbird> Now we're talking.
[22:14] <HtheB> willmore: ?
[22:14] <OffensiveUser> spoiler: we were talking all along
[22:15] <methuzla> Warbird: you might want to look through back issues of the MagPi, you'll probably find very similar projects in there
[22:15] <Warbird> That looks like a home run. I'm a tad concerned that the cord might be too thick to run without keeping my window from closing.
[22:15] <methuzla> http://www.raspberrypi.org/magpi/
[22:15] <willmore> HtheB, you can set the SPI clock speed when loading the display driver module. According to the datasheet for the ili9340, the max clock speed is close to 6.6MHz.

[22:49] <shiftplusone> not really, it comes back to my Monday example. If my code stops working on a Monday, it's not because of the Monday.
[22:50] <meLon> I'm suggesting that the archlinux-arm devs are focusing on other platforms and have neglected to do thourough testing on each of their releases for the pi, is all.
[22:51] <meLon> For example, I may find that between two versions, a feature was added, or something was replaced with something else that could cause issues.
[22:51] <shiftplusone> and if a raspberry pi engineer suggested that it would be a good idea to rule out power and sd card issues first?
[22:51] <meLon> This isn't the first time I've found a regression bug such as this.
[22:51] <meLon> I would absolutely listen, and do the tests, and provide the information gathered
[22:51] <shiftplusone> hm
[22:51] <meLon> Because of my useage of multiple SD cards, I'd like to rule out SD cards being the issue, however

[22:52] <shiftplusone> it's across the other side of the board.
[22:53] <ColdKeyboard> From time to time my raspberry crashes, I can't get more uptime than 4-5days before I have to manually power it off/on to start working
[22:53] <meLon> ColdKeyboard: 'journal' and 'dmesg' have NO INFORMATION, even after tens of crashes
[22:53] <shiftplusone> ColdKeyboard, if it crashed in a way that would allow it to log the issue. Check /var/log
[22:53] <meLon> ColdKeyboard: we're talking about minutes (under ten) vs hours (over 8)

[23:00] <willmore> Thanks, shiftplusone. Looks like Mr. Drogon found it to be 32MHz and that there are signifigant limitations on the clock setting.
[23:01] <willmore> Of course that post is 2.5 Years old and I'm pretty sure I saw some patches to make the clock speed setting better.

[23:19] <Warbird> Details how to use the temp sensor I'm buying.
[23:19] <Warbird> How in the hell am I going to hook up two servos/engines/steppers/Idon'tknow up as well?
[23:19] <Ryccardo> Warbird: aha, that's the one designed for use with my... real time clock
[23:20] <Warbird> As opposed to an unreal time clock?
[23:20] <shiftplusone> Ryccardo, why the... pause?

[23:22] <shiftplusone> ah yes, of course.
[23:22] <Warbird> It could do my taxes and I'd be fine with it. I just want to run two servos and the sensor off of the Pi. IS that even possible?

[23:28] <OffensiveUser> why's that preferable over say, using a dc motor to turn some rope/chain/wire in a loop attached to the curtain
[23:29] * Tach[Out] is now known as Tachyon`
[23:29] <OffensiveUser> maybe a pulley in the middle if it's that kind of curtain
[23:29] <Warbird> The reel solution lets the tension be held without having the motor run all the time.
[23:29] <Warbird> Unless there's one that doesn't. I have no idea what I'm doing.
[23:30] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 256 seconds)
[23:30] <OffensiveUser> picture of the curtains you wanna automate?

[23:31] <Warbird> I'm not at the house. I'll see if I can find a comparable pic.
[23:32] <OffensiveUser> k
[23:32] <Warbird> It's just a cheap extend rod thing and a single sheet curtain from WalMart.
[23:32] <methuzla> Warbird "servos" typically mean hobby servos, which only have +/-90deg of travel, except for some that have been hacked to be continuous rotation
[23:33] <methuzla> but a DC or stepper motor would probably be a better choice
[23:33] * McAFK is now known as McBride36

[23:41] <OffensiveUser> have some wire going between them
[23:41] <Warbird> The plan is to have a string looped around the bottom bit of the curtains and have it pulled to one side al la http://www.internethomealliance.org/wp-content/uploads/2010/09/curtain-center.jpg
[23:42] <McBride36> you can use a dc motor that spools the sring
[23:42] <McBride36> string*
[23:42] <Warbird> Does it have to continue to run to maintain tension?
[23:42] <OffensiveUser> that'll work too
[23:43] <OffensiveUser> doing it from the top and sliding the curtain open is a set up that wouldn't
[23:43] <McBride36> i don't think it would
[23:43] <McBride36> but you can use another mechanism to prevent the spool from despooling
[23:43] <Warbird> Like a fishing reel.
[23:44] * Fishy_ is now known as Fishy
[23:44] <Warbird> And sliding from the top isn't going to happen. They'll just fall off, rod and all.

[23:52] <Warbird> I have no idea. The idea is for the curtains to be drawn while I'm still asleep so I get dark at night and sun when I get up.
[23:52] <Warbird> So no particular hurry. Nothing too loud though.
[23:53] <ozzzy> are these drapes or blinds

[23:56] <McBride36> wiringpi is the library
[23:56] <McBride36> for controlling the pins
[23:56] <McBride36> and the L293D is just an H bridge
[23:56] <ozzzy> wiringpi gives simple access to the pins... l293d is a motor driver chip and voltage could be a wallwart
[23:56] <McBride36> for controlling direction
[23:56] <ozzzy> an arduino would be cheaper

[23:56] <McBride36> yeah, and easier
[23:56] <McBride36> hardwired PWM output
[23:57] <ozzzy> I don't think pwm is really needed here... just a motor that turns the right speed
