[0:39] <exxy-> I'm just trying to open Midori on the display connected to the HDMI from terminal. I've spent 4 hours trying to do so.
[0:39] <chod> is the pi configured to use hdmi
[0:40] <exxy-> I cannot open anything on the xserver that is currently handling the HDMI display.
[0:40] <exxy-> It will not allow me to connect to display :0, I'm assuming it's because by default it's started with -nolisten tcp
[0:40] <exxy-> I have no idea where to find that startup line so I can remove the -nolisten tcp and see if that fixes it.
[0:41] <chod> you can ssh in ok?
[0:41] <exxy-> Yeah.
[0:41] <exxy-> I'm SSH'd into the Pi, the display is showing the desktop.
[0:41] * dangerousdave (~dangerous@ Quit (Quit: Leaving...)
[0:42] <chod> can you not Midori &
[0:43] <exxy-> I'm running Raspbian/Wheezy, if I type "midori --display=:0 -a www.google.com" I get the error "Protocol not specified, Midori cannot open display:"
[0:43] <exxy-> I definitely want to display it on :0 because that's most certainly the display that is handling the HDMI output on the Pi
[0:43] * zz_slm4996 is now known as slm4996
[0:43] <exxy-> because if I kill the process, it resets and my display blinks and all this jazz.
[0:45] <chod> yes i get cannot open display
[0:47] <exxy-> It's weird though, I did a bunch of research and the closest I got was by manually setting my hostname to localhost..
[0:48] <exxy-> when I did that, I could open it, but then when I rebooted the Pi, it wouldn't start the xserver correctly.
[0:48] <exxy-> I have no idea why.

[0:50] <exxy-> Hmm, I just got it work without using sudo in front of the command.
[0:50] * dRbiG (drbig@ has joined #raspberrypi
[0:53] <chod> which syntax
[0:53] <kkit> exxy-, sounds like you need to use xhost, perhaps
[0:54] <exxy-> kkit: what does that do? I saw a ton of stuff about it but it wasn't a working command so I assume I have to install that.

[2:43] <mark4> does config.txt have to list a kernel file?
[2:43] <mark4> th eone i have does not specify one. i the officail debian on here a few moments ago
[2:44] <nechayev> I want to use the rpi as a thinclient type computer, and have it hooked up to my laptop which itself will do the brunt of the processing, and the pi merely displaying and outputting sound......firstly, would this be better served via ssh xforwarding, or a vpn, etc? Secondly, what distro would i be best suited with? I am tied, for this purpose, largely between tinycore, and openwrt.
[2:44] <mark4> and it booted fine but the kernel was called kernel.img
[2:44] <mark4> openwrt runs on a pi?
[2:45] <clever> mark4: kernel.img is the default if you dont list a name in config.txt
[2:46] <nechayev> Its listed on the rpi distributions page and they have an image for the pi havent tried it. Tinycore is brilliant.
[2:48] * sleetdrop (~sleetdrop@ has joined #raspberrypi

[2:58] <SpeedEvil> it will work for basic pointing and clicking on stuff, but any moving content will cause issues

[3:02] <nechayev> Yeah ive used bodhi a fair bit, fairly usable for one, simple tab lol....my problem is more or less a laptop with only vga output, a tv with vga and hdmi, but obviously i would like the sound as well, thought the pi might be a decent 'till i can budget a new comp' workaround.

[6:31] <nsgn> would be helpful if i had a mouse attached
[6:31] <nsgn> or a keyboard
[6:31] <nsgn> i have neither
[6:31] <nsgn> it is the pi i strapped to the back of a monitor to run my camera viewing pi app. x decides to sleep the screen which kindof defeats the point
[6:32] <kkit> xset -dpms
[6:33] <nsgn> kkit, problem is where do i put that which has enough permission on startup?
[6:34] <nsgn> anything within the user pi does not seem to cut it
[6:34] <kkit> your user's xinitrc?
[6:34] <nsgn> i'll try again but when i tried that it didn't seem to take effect
[6:35] <nsgn> and googling why has people saying the user pi, which of course is where x launches by default, does not have adequate permissions to do that with xinitrc
[6:36] <nsgn> although on the particular pi i have in front of me right now xset seems to not be available??
[6:36] <[Saint]> solution - kill pi and make a 'real' user...?
[6:36] <kkit> Maybe you need another package

[6:37] <[Saint]> getting rid of 'pi' is one of the first things I do on the raspbian image.

[10:33] <gordonDrogon> morning.
[10:33] <gordonDrogon> Gadgetoid, I'd love a laser cutter...
[10:33] <neilr> friend of mine built a plasma cutter in his shed...
[10:34] <[Saint]> Yeah...you could really shank up some bitc...errr, make some crafts.
[10:34] <[Saint]> ...yes, crafts.
[10:34] <gordonDrogon> I looked at making one - I have an A4 flatbed here, did some research... did a lot of research... gave up. it's not a task to be taken lightly...
[10:35] <gordonDrogon> plasma cutter - I've used a hand-held one to cut metal - making of from scratch - er ... right!
[10:35] <neilr> He's one of those people that just builds stuff in the the way that children scribble doodles on paper. Also built a 3-axis CNC machine.
[10:35] <neilr> And built his kitchen from a couple of oak trees.
[10:35] <gordonDrogon> I wish I had a workshop where I could tinker like that...
[10:36] <neilr> His latest toy is some kind of rangefinding laser, which he wouldn't tell me where it came from.
[10:37] <neilr> While I'm wittering on - back to yesterdays topic. Pi and nixie tubes... What hardware would I need to drive 6 tubes from a pi? I have a bit of an idea...
[10:38] <neilr> A transformer of some kind
[10:38] <neilr> some sockets
[10:38] <neilr> wire
[10:38] * risc (~toor@freebsd/user/risc) has left #raspberrypi
[10:38] <gordonDrogon> there are some nice driver chips that'll handle the voltage - you're looking at switching c180 volts.
[10:39] <gordonDrogon> or you make your own out of high voltage transistors.
[10:39] <gordonDrogon> from what I remember from my last forray into research, there are even some bases now that take ttl inputs - so the tube bases are the clever part. you just heed the HT PSU and something to drive them.
[10:40] <gordonDrogon> depending on how "close" to the switching you want to get.
[10:40] <neilr> Errr, the phrases "making my own" and "high voltage" probably won't sit well with my wife :)
[10:40] <onefreeman> just make a Jacob's Ladder for the living room, she'll be cool
[10:40] <neilr> As simple as possible on the hardware front really
[10:40] <gordonDrogon> yea, start iwth a jacobs ladder. I've always wanted one of them.
[10:41] <neilr> I mentioned a Tesla Coil once. I wasn't allowed one.
[10:41] <gordonDrogon> if you want simple, spend the money on a ready made one and hack it so you can drive the tubes with your own driving PC thing.
[10:41] <gordonDrogon> tesla coil is on my to-do list too. I have Dartmoor behind me too, so lots of space...
[10:41] <neilr> mmm. I may put some time into this later today. Happy to spend a few quid on parts.
[10:42] <neilr> I live in The Fens. Similarly, space isn't a problem
[10:42] <neilr> The idea of the children asking mum why dad is late for tea, and incidentally, what's that pile of ash on his shed floor? That's what stops me :)
[10:44] <neilr> http://www.ebay.co.uk/itm/IN-18-or-IN-4-NIXIE-TUBE-HV-DRIVER-BOARD-CODE-SAMPLE-/261178119966?pt=UK_Sound_Vision_Other&hash=item3ccf6dd71e

[10:50] <neilr> The IN-4 nixie tubes don't seem to be prohibitively expensive
[10:51] <gordonDrogon> they're the end-facing ones.
[10:51] <neilr> That's fine - just as a proof of concept.
[10:51] <gordonDrogon> PSUs are ?12 too.
[10:52] <neilr> But I'd only need one, right?
[10:52] <gordonDrogon> Yes, I think so.

[10:53] <gordonDrogon> e.g. West Sussex too.
[10:53] <neilr> Plan is to drive six nixie tubes from a pi - ordinarily to show the time, but also date, temperature, number of unread emails, time left until tea etc. etc.

[10:55] <neilr> That's handy - it has a regulated 5V output. So in theory, I could power the pi as well as a tube

[10:57] * HashNuke (~HashNuke@ Quit (Quit: Textual IRC Client: www.textualapp.com)

[10:58] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 264 seconds)
[10:59] <neilr> Still, it would be interesting to see how many IN-4 tubes that supply would drive
[11:01] <gordonDrogon> I suspect quite a lot - you're only driving one cathode on each tube - and it's 1-5 mA per tube when lit.
[11:01] * cccyRegeaneWolfe is now known as cccy_RegeaneWolf
[11:02] <gordonDrogon> and that description says it has 2 outputs for bigger tube projects, ... he's probably not far from you either, but I've seen him a lot on ebay, so been doing it for a while, so drop him an email..
[11:02] * omgmog (~omgmog@ Quit (Quit: Computer has gone to sleep.)
[11:02] <neilr> I think I may be buying some bits this afternoon.
[11:02] <Gadgetoid> gordonDrogon: surprised it's so complex to build a laser cutter, thought the only major requirements were safety and a good power supply
[11:03] <neilr> So... How would you interface these to the pi? That's the bit I'm least sure about
[11:05] <gordonDrogon> Gadgetoid, most tubes I looked at needed 3 voltages - 18Kv, 22Kv and someting else. then there's the water cooling. then there's the box to put it all in, fume extractor - cutting plastic produces mildly toxic fumes. wood less so, but plywood has some interesting glues, etc. safety goggles, height control for focusing ... I gave up at that point.
[11:05] <gordonDrogon> neilr, use a driver IC - these are usually TTL inputs - I'd see if they trigger at 3.3v but if not, then I'd use a buffer of some sort to drive the drivers. If paranoid, then use opto isolators.
[11:05] <Gadgetoid> gordonDrogon: Ah, yes, fumes, but??? wait??? water cooling?
[11:06] <Gadgetoid> Perhaps the difference between etching and cutting is more profound than I expected
[11:06] <gordonDrogon> I was looking at 40 watt tubes... seems to be the minimum for commercial cutters.
[11:07] <Gadgetoid> Wonder if heated wire cutting would work, hmm
[11:07] <Gadgetoid> Probably not!
[11:08] <Gadgetoid> Wonder what happens if I pass too much currant through Bareconductive paint

[15:25] <ShiftPlusOne> ganbold, they don't provide much information there. From what I gather, it's 5v and uses 1 pin to read and write, so you'll need some bidirectional level conversion. I may be wrong about that, but I think there are better options out there.

[16:15] <gordonDrogon> SwK, and wiringPi v2 doesn't really support it either.
[16:16] * Gadgetoid hears wiringPi v2
[16:16] <Gadgetoid> I was looking at the docs for the MCP23017 and was interested in interrupts, actually
[16:16] <gordonDrogon> however if you're poking the registers directly yourself, then you can enable a pin-change interrupt - then you need to connect the interrupt line from the 23x17 to an ordinary gpio line on the Pi, then you can get an interrupt from it.
[16:17] <Gadgetoid> I wonder if the interrupt line is connected on any of the boards, there's a jumper on the Quick2Wire board for I2C interrupt
[16:17] <gordonDrogon> I thought about the whole interrupt handling cases - and felt they would be few and far-between.
[16:17] <gordonDrogon> the PiFace has the interrupts lines connected to GPIO lines - apparently.
[16:17] <gordonDrogon> the mcp23x17's have 2 interrupt lines.
[16:17] <Gadgetoid> gordonDrogon: True, that, I was looking into it out of interest rather than anything else
[16:17] <Gadgetoid> Oh one for each set of pins?
[16:17] <Gadgetoid> Makes sense
[16:18] <Gadgetoid> Presumably interrupts on anything more than a single IO expander just become a big complicated mess, too

[16:27] <ganbold_> cool, IR works on raspbmc
[16:27] <SwK> I have a MCP23017 and a MCP23008 thats 3 interrupts, I was thinking of tying them all to 1 gpio pin via an OR then just scan them all on interupt

[16:32] <gordonDrogon> SwK, if they're open collector outputs, then that will work. just enable the internal pull-up on the Pi's pin.
[16:33] <SwK> gordonDrogon: I think they are all open collector
[16:33] <SwK> even if I had to put a physical OR gate in there i think I'm ok with that
[16:34] <gordonDrogon> If they're OC then you'll be fine. You just need a pull-up.

[16:50] <gordonDrogon> the important bit is: HD44780 - that's the common LCD driver display chip.
[16:50] <gordonDrogon> see this: https://projects.drogon.net/raspberry-pi/wiringpi/lcd-library/
[16:51] <aaa801> aha so it should be compatible with wiringpi?
[16:51] <gordonDrogon> someone showed me an ebay page with these LCDs that had my name on them - I guess they were using a Pi with my software to demo them on ebay!
[16:51] <gordonDrogon> oh yes - they work with wiringPi.
[16:51] <aaa801> :D
[16:52] <aaa801> cool, even through io expanders ?
[16:52] <aaa801> do you just define the pins or ?
[16:52] <ReggieUK> did anyone do any work on reducing the pin count needed for those screens on a pi?
[16:52] <gordonDrogon> with wiringPi v2 it will be trivially possible to use them via gpio expanders - that's actually next on my testing list.
[16:52] <aaa801> Aha cool, il have it set up for testing soon
[16:52] <gordonDrogon> ReggieUK, use an I2C expander or shift registers.
[16:53] <aaa801> just got to connect the data lines
[16:53] <Gadgetoid> gordonDrogon: Reminds me, I tried soft PWM or soft Tone on a GPIO extender
[16:53] <gordonDrogon> ReggieUK, you need 6 bits to control the display.
[16:53] <gordonDrogon> Gadgetoid, and... ?
[16:53] <Gadgetoid> I might have mentioned this, I don't think anything much happened
[16:53] <ReggieUK> 4 according to this:

[18:01] <nid0> if they were going to make a pi that could accept that (and drop the voltage it outputs down to 5V from 7.5) they might just as well add poe directly, its not an inherently expensive system to add
[18:02] <clever> nid0: in the etherten setup, the 2 pins are simply broken out to a header, beside an extra power input, giving you 3 options
[18:02] <clever> 1: just jumper it, direct power!
[18:02] <clever> 2: crude voltage regulators
[18:02] <clever> 3: proper poe adapter

[18:03] <clever> the poe regulator on that site is $29, almost doubling the cost of your pi
[18:03] <clever> not something you would make standard
[18:04] <clever> but a 4 pin header on the pcb makes it much easyer to connect
[18:04] <nid0> eh? just because that addon board that fits an arduino and doesnt output the right power for a pi costs $30 doesnt mean directly integrating poe into a pi costs $30
[18:05] <clever> oh, didnt notice it outputs 7.5
[18:05] <clever> yeah, it would need a bit of tweaking then

[18:05] <IT_Sean> integrating POE would mean a board redesign, and would be of little to no benefit to the Pi's target audience. I rather doubt it'll happen.
[18:05] <clever> IT_Sean: yeah, thats why i was thinking of a 4 pin header like the etherten
[18:05] <clever> simply breaking out the 2 pins from the magjack, and the power in
[18:05] <nid0> me neither, despite having had my hopes up from the faq they've never updated, but it would be a more useful feature than just bloating ram up to 2GB
[18:05] <clever> then you have an optional daughter board to handle the poe

[19:34] <gordonDrogon> it has to be set to input first.

[19:37] <clever> vitruvio: if its unplugged, you will get random readings
[19:37] <gordonDrogon> an input pin is normall tristate anyway - unless you've set the internal pull-up or pull-down resistors.
[19:37] <clever> if you want to measure 0 on the adc, you need to connect it to 0v
[19:37] <vitruvio> clever: but as high as 1 v?

[19:39] <vitruvio> any resistance sugestion?
[19:40] <clever> depends on what you want to input normally
[19:40] <gordonDrogon> the Adafruit ADS1015 shoudl read zero when an input is connected to 0v.
[19:41] <gordonDrogon> and it should read max (ie. 4095) when connected to Vcc.
[19:41] <clever> if your input is a pot, then the pulldown will change the output range, you effectively have 2 resistors in parallel, which are then in series with a 3rd
[19:41] <clever> gordonDrogon: yep
[19:41] <gordonDrogon> but if nothing is connected then it will rad a random value.
[19:43] <vitruvio> my concern is if wire get unconnected
[19:43] <pksato> vitruvio: that you measure with adc?
[19:44] <gordonDrogon> vitruvio, if a wire is unconnected then it wil lread a random value.

[19:53] <gordonDrogon> troulouliou_dev, technically yes - it's very high impedance, but it's not infinite.
[19:53] <vitruvio> yes but only want to ensure that in any case this 1 v in my channel 0 is not an unpluged wire
[19:54] * robscomputer (~robscompu@nat/yahoo/x-herxkkkmthzgdkjs) Quit (Read error: Connection reset by peer)
[19:54] <gordonDrogon> vitruvio, it's impossible to tell if it's unplugged or not.
[19:55] <vitruvio> but with some pulldown resistor that make read 0 when calbe is unpluged, and of coure that doesn't affect true readings
[19:55] <troulouliou_dev> gordonDrogon, when connecting a button for instance i need to wire it between VC and groud with a pull up or down resistor and connect the gpio below or above the resistor right ?
[19:55] <gordonDrogon> you could do that - with a high value resistor - but how wil lyou then know it's unplugged or the source sending 0v ?
[19:55] <gordonDrogon> troulouliou_dev, you need a pull-up or pull-down. The Pi has them internally.
[19:55] <vitruvio> the source will never send less than 0.5v
[19:55] <vitruvio> 0.5-4.5 is his range
[19:55] <gordonDrogon> vitruvio, in which case a 1M resistor to 0v might work for you.
[19:56] <troulouliou_dev> gordonDrogon, ? i need it or not ?
[19:56] <gordonDrogon> troulouliou_dev, you do need one.
[19:56] <vitruvio> 1000 ohms or more, probably I haven'r thie exact value
[19:56] <troulouliou_dev> and if im using a dip switch on 4 pin i need one resistor per pin ?
[19:56] <gordonDrogon> troulouliou_dev, connect gpio pin -> switch -> 0v and enable the internal pull-up.
[19:57] <gordonDrogon> troulouliou_dev, the pin will read 1 until you push the button then it will read 0.
[19:57] <gordonDrogon> troulouliou_dev, yes, but the Pi has the built in.
[19:57] <gordonDrogon> vitruvio, go as high as possible so it doesn't affect the thing you're reading.
[19:58] <pksato> troulouliou_dev: to clear, you not need a external pull-up resistors.
[19:58] <vitruvio> I'll check how affect to readings and maybe add this in script

[19:59] <vitruvio> maybe is fix the difference in whole range
[19:59] <troulouliou_dev> some how confused ; the pull up has to be enabled programaticaly ?
[20:01] <troulouliou_dev> gordonDrogon, connect gpio pin -> switch -> 0v and enable the internal pull-up. ... ?
[20:02] <gordonDrogon> troulouliou_dev, yes, you enable it in your program, or from the command-line.
[20:02] <troulouliou_dev> gordonDrogon, it is the same in out mode ?
[20:03] <vitruvio> Thank you all
[20:03] <gordonDrogon> troulouliou_dev, no - in output mode, it's just an output.
[20:03] <gordonDrogon> troulouliou_dev, the internal pull up/down resistors have a value of about 50K??
[20:04] <troulouliou_dev> gordonDrogon, really good info totally didn't know about that .Is it common on allboard like arduino / teensy ... or specificto pi

[20:05] <gordonDrogon> troulouliou_dev, it's very common.
[20:06] <gordonDrogon> troulouliou_dev, all microcontrollers have them. usually just pull-up, but sometimes both pull-up and down.
[20:06] <gordonDrogon> it saves a resistor on the circuit board, which can save 1p - so if making a million things it saves quite a lot...
[20:07] <gordonDrogon> e.g. on the Pi - there is a switch that senses the SD card being plugged in - they connect that to a GPIO pin and enable the internal pull-up. It saves them one resistor so keeps the cost down.

[20:11] <troulouliou_dev> gordonDrogon, so when setting the pin in in mode i llhave 3.3on it and then when activating the pull up and connecting to ground it will be 0 and the 3.3 will be above the internal pull up
[20:11] <vitruvio> but of course know when cable is unplugged i get 0
[20:12] <vitruvio> *now when
[20:12] <vitruvio> thank you again
[20:13] <gordonDrogon> vitruvio, where are you getting this 3.294 from?
[20:13] <vitruvio> 3.3 vcc from p1 connector
[20:14] <gordonDrogon> troulouliou_dev, in input mode, the pin will be random. so you need to connect a high value resistor to either +3.3v or 0v. the switch goes to the other side, then the pin is biased one way and the switch pulls it the other way.
[20:14] <gordonDrogon> vitruvio, if the register reads 4095 then that = 3.3v not 3.294
[20:15] <vitruvio> Iet me change the script and see what read, it is adafruit sample scrit and have converted to volts

[20:17] <gordonDrogon> the calculation is simple: it's the reading divided by the max. reading times 3.3.

[20:23] <gordonDrogon> the chip works relative to Vcc - so if you feed it 5V then the max value of 4095 = 5v

[20:52] <clever> sambenji: you might not be able to give it enough current to keep the voltage up
[20:52] <sambenji> gordonDrogon / clever is it possible the model a has a different power requirement?
[20:52] <sambenji> as it's running off the exact same adapter

[20:54] <sambenji> clever: is there any way to specifically test for that? or is the easiest way to use a powered hub and see if the issue persists?
[20:54] <pksato> sambenji: Model A? one USB, no ethernet?
[20:54] <gordonDrogon> sambenji, model A should use much less power than the B.

[20:55] <Gadgetoid> I guess I'd better make a start on WiringPi-Python, deary me
[20:55] <pksato> or, is a software issue.
[20:55] <sambenji> gordonDrogon: leaving more available to the wifi adapter than the B you'd assume, right?
[20:55] <Gadgetoid> gordonDrogon: Any major updates to 2.0?
[20:55] <clever> pksato: he said he's using the same sd card on both
[20:55] <clever> pksato: so the software is identical
[20:55] <sambenji> yeah, same sd card
[20:55] <pksato> No userlevel software.
[20:56] <pksato> usb kernel module issues.
[20:56] <sambenji> pksato: it's the same module..
[20:56] <pksato> but, dont have a SMC hub attached.
[20:56] <gordonDrogon> sambenji, yes - it should be better on the A if anything.
[20:56] <clever> sambenji: do you see F1 and F2 on the pcb?
[20:56] <gordonDrogon> Gadgetoid, not yet.
[20:57] <sambenji> clever: yup
[20:58] <pksato> sambenji: you have a multimeter to check tp1-tp2 volts?
[20:58] <clever> sambenji: only one present on the model a?
[20:58] <Gadgetoid> Right, Then I need only suddenly start not sucking at Python!
[20:59] <pksato> some board (A or B) have a damaged F3 polyfuse.

[21:01] <clever> try measuring the voltage at tp1->tp2 like pksato said

[22:11] <Gadgetoid> gordonDrogon: Most likely!
[22:11] <Tenkawa> gordonDrogon: -Wall just turns on all warnings

[23:23] <ShiftPlusOne> from kernel onwards though, you can use qemu

[23:23] <ryao> ShiftPlusOne: I am more interested in figuring out what went wrong inside my initramfs when I tried changing the rootfs to ZFS without having to fiddle with the physical hardware. :/
[23:24] <ryao> Anyway, thanks.
[23:24] <ShiftPlusOne> is that built into the kernel or a separate file?
[23:24] <ryao> ShiftPlusOne: It was built into the kernel. Why do you ask?
[23:25] <ryao> ShiftPlusOne: The issue had to do with shared libraries. Strangely enough, they work fine in a chroot, but when the kernel loads it, they break.
[23:25] <ShiftPlusOne> Wondering if you're relying on the bootloader to handle it or the kernel.
[23:25] <ryao> ShiftPlusOne: I did not know that the raspberry pi bootloader could load it.

[23:31] <gordonDrogon> Gadgetoid, ok... Yes - I've had issues with people fetching it from github and then not being able to compile it )-:
[23:32] <ShiftPlusOne> [Saint], it means we have their permission to be here, they have op accounts and ownership of the channel will be transferred to them if they ask.
[23:32] <Gadgetoid> gordonDrogon: I think the message you added to your README made it up in my most recent commit
[23:32] <gordonDrogon> ok

[23:40] <[Saint]> That may also be handy to have in the topic. :)
[23:40] <gordonDrogon> it's been there for ever ..

[23:40] <ShiftPlusOne> There are also plenty of channels for the distros

[23:40] <Gadgetoid> It's not obvious that it's there
[23:40] <ryao> [Saint]: is your inquiry in reference to my question? It seems like a support question to me. :/
[23:41] <[Saint]> ryao: no - not at all.
[23:41] <gordonDrogon> the best "support" you'll get is probably via the forums though.
[23:41] <ShiftPlusOne> But yeah, it's not like support questions are drowned out here. This is a support channel after all... we just tolerate offtopic and general discussion. If support questions were getting drowned out then that would be another issue.

[23:45] <Gadgetoid> I definitely shouldn't be programming with a brain this addled, I just realised my installed library isn't working because Python is favouring the identically named files in the build root of same said library
[23:45] <ShadowJK> huh
[23:45] <ShiftPlusOne> Is that a hardware feature or a software feature?
[23:45] <ShadowJK> hardware
[23:45] <ryao> Hardware
[23:45] <ShiftPlusOne> ryao, they are focusing on software right now. I don't think they'll be making any hardware changes any time soon.
[23:45] <gordonDrogon> ryao, unlikely.
[23:46] <ShadowJK> I'd make a guess the SOC doesn't support it
[23:46] <ShiftPlusOne> and the education side of things as well
[23:46] <IT_Sean> I would place good money on the SOC not supporting it.

[23:49] <gordonDrogon> what's the A/D on the quick to wire board?
[23:49] <Flasking23> yes :)
[23:50] <gordonDrogon> [Saint], probably not.
[23:50] <Elspuddy> o.k how do i update locate/mlocate ?
[23:50] <ryao> The Raspberry Pi needs open source firmware
[23:51] <gordonDrogon> if you install it, then leave your Pi on over night. I think it does its thing round about 5:30am

[23:51] <[Saint]> ryao: well, unfortunately - and unsurprisingly - broadcomm likes making money, so, you can give up on that wish.
[23:51] <gordonDrogon> Elspuddy, oh, in that case: cd / find . -name foobar

[23:53] <Gadgetoid> gordonDrogon: They can be separated, but I'm not sure it's worth the bother unless it starts to get huge
[23:54] <gordonDrogon> GPU technology is full of patents, company secrets and other secret sauces - no-one wants the opposition to know what they're up to ...
[23:54] <gordonDrogon> Gadgetoid, nah.
[23:54] <ryao> [Saint]: I do not think that they can sell the hardware without giving it to you. You need the hardware to boot.
[23:55] <[Saint]> ryao: they don;t have to give you the source, though.
[23:55] <[Saint]> ...which is what you're talking about.
[23:55] <ShadowJK> ryao; broadcom is pretty firmly on the axis of evil when it comes to opensource, so I wouldn't hope for much. That they made it possible to boot an unsigned, semi-recent linux kernel is a miracle in itself
[23:55] <ryao> [Saint]: Failing to provide the soucre does not give them money though.
[23:55] <[Saint]> ryao: sure it does.
[23:56] <Elspuddy> o.k now i see where im going wrong,
[23:56] <gordonDrogon> if one of their competitors knew how the GPU worked, then they could make a better one, so they would get more sales, etc.
[23:56] <ShiftPlusOne> The information on how the GPU works can be found in the patents.
[23:56] <ShadowJK> ryao; they charge separately for knowledge how to unlock or use specific hw features :P
[23:56] <gordonDrogon> so by not giving away the "crown jewels", you protect your sales and profits...
[23:56] <Gadgetoid> Glorious glorious LEDs, all lighting up as they should!
[23:57] <ShiftPlusOne> And the instruction set has been reverse engineered so.... yeah, there aren't too many secrets left there.

[23:57] <gordonDrogon> :)
[23:57] <ryao> gordonDrogon: That is silly. people make better ones all the time. Also, the source code does not reveal very much. It is not like giving out the hardware blueprints.

[23:59] <ShadowJK> ryao; broadcom has always been anti-opensource, and extremely well known for it too. I'd suggest you look for something else if it's important to you. If everyone does this, the friendly company would get more sales and do better than unfriendly companies :P
[23:59] <clever> ShiftPlusOne: have you seen the stuff about baremetal pi?
[23:59] <gordonDrogon> it won't reveal the details of the internal pipelines and possibly things like register locking.
