[0:19] <calimero_82> today is arrived raspb v.2, i've bought this loader: input AC 100-240V 50/60Hz 150mA output 5.oV 2.1A is ok?
[0:21] <Macuser> heh?
[0:22] <Macuser> I see my nick was mentioned
[0:22] <Macuser> But I can't find it

[0:27] <ali1234> Kamilion: i had to repair a leaking battery on my A4000, it can be worse that it looks especially if the leak goes under chips
[0:27] <ali1234> you really need to repair it ASAP as it will only get worse even if the battery is gone
[0:27] * jkridner (~jkridner@pdpc/supporter/active/jkridner) Quit (Ping timeout: 256 seconds)
[0:27] <Kamilion> ali1234: I cleaned it properly with acid neutralizer and flux.
[0:28] <Kamilion> i just didn't solder on the header pins yet
[0:28] <ali1234> does A2000 use SMT parts?
[0:28] <IIsi50MHz> 14:17:14 <IIsi50MHz> Ooo, a Macuser. I've rather a lot of olde MacUser mags.
[0:28] <IIsi50MHz> 14:19:48 <IIsi50MHz> And operational an Quadra 700, PowerMac 6400/G3 upgrade. My G4 MDD needs a new OS; MintPPC is sluggish. My IIsi is a doorstop.
[0:28] <Macuser> ohhh
[0:28] <ali1234> because A4000 does, and the traces under them were completely gone
[0:28] <Macuser> Yeah that's my name isn't with a capital "u"
[0:28] <Macuser> I'm not the UK magazine
[0:29] <IIsi50MHz> Mine are all U.S. editions.
[0:29] <IIsi50MHz> None newer than 1997.10
[0:29] * Berg (~chatzilla@pa220-236-49-55.pa.nsw.optusnet.com.au) has joined #raspberrypi
[0:29] <Kamilion> ali1234: it's been about a year since I recovered it, and i clipped the battery and cleaned the board less than a week after getting a hold of it.
[0:30] <Kamilion> it was just barely beginning to sweat tiny blue crystals on the postive end of the cell before I removed it at the base of the board.
[0:31] * RoghanJosh (~RoghanJos@11.pool80-103-49.dynamic.orange.es) Quit (Quit: Leaving)
[0:31] <Kamilion> doused it's outline in flux and used the flux cleaner to remove it
[0:32] <Kamilion> scrubbed it with isopropyl, let it dry, and left it.
[0:32] <ali1234> did you check under the CPU?
[0:32] <Kamilion> uh?
[0:32] <ali1234> looks like the battery is right next to it
[0:33] <Kamilion> ah, right
[0:33] <Kamilion> no, i have a different revision board with the PLCC m68k

[0:34] <Kamilion> n/m, that's not the m68k, lol
[0:35] <Kamilion> it's a rev 4.4, yes, it's right next to the CPU, and yes, it does look like I desocketed it and cleaned under it.
[0:36] <Kamilion> mistook the "fat lady" for the m68k. God, this DIP seems huge.
[0:36] * pksato (~PEBKAC@unaffiliated/pksato) has joined #raspberrypi
[0:36] <Kamilion> eeeh. looks like i need to soak the I/O ports with contact cleaner and give them a good scrub
[0:37] <Berg> still broken is thyat sourceforge ...anyone have duct tape?
[0:37] * langlee (~bob@ has joined #raspberrypi
[0:38] <ali1234> i don't think the PLCC chip is the CPU
[0:38] <ali1234> could be i guess
[0:38] <Kamilion> Berg: have you tried a sf mirror?
[0:38] <Berg> surely
[0:38] <Kamilion> ali1234: later m68ks were plcc, this one's apparently one big fat honkin DIP like my atari ST's was.
[0:39] <ali1234> right
[0:39] <ali1234> the PLCC chip on A2000 is agnus

[1:27] <sflw> Hi all, I'm looking to start a project that involves my RPi receiving a text message and then firing a piston that strikes a gong. Haven't really seen anything out there I can use a reference to get started. Does anyone in here know of some projects I could look at?

[1:34] * darkbasic (~quassel@niko.linuxsystems.it) Quit (Ping timeout: 240 seconds)
[1:35] <mirana2s> seriously.. the only way to contain applications on raspb is chroot? I can't find any sensible options
[1:36] <CoJaBo> ?
[1:36] * ozzzy_ (~ozzzy@unaffiliated/ozzzy) has joined #raspberrypi
[1:36] * darkbasic (~quassel@niko.linuxsystems.it) has joined #raspberrypi
[1:37] <pksato> mirana2s: docker? http://blog.xebia.com/2014/08/25/docker-on-a-raspberry-pi/
[1:37] <mirana2s> I guess that's my only option
[1:38] <mirana2s> apt-get docker just gave me some gnome2 tool though
[1:38] * ozzzy (~ozzzy@unaffiliated/ozzzy) Quit (Ping timeout: 240 seconds)
[1:40] <sflw> CoJaBo: I guess the mechanical part. I think I can figure out the text messaging part. It's just coding after all.
[1:40] * gbaman (~gbaman@ has joined #raspberrypi
[1:41] <mirana2s> I heard mechanical. what are you building?
[1:41] <CoJaBo> sflw: You need to settle on a mechinism to hit the gong, and something to drive that from the GPIO input
[1:42] <sflw> CoJaBo: I suppose what would be easiest is something that can spin quick enough that, when some sort of mallet is attached to it, the gong is loud enough to be heard.
[1:42] <sflw> In that case I suppose what I need is some kind of fast-moving servo?
[1:42] <CoJaBo> A solnoid, more likely
[1:42] <CoJaBo> Probably 120VAC
[1:43] * _BigWings_ (~Thunderbi@modemcable119.79-19-135.mc.videotron.ca) has joined #raspberrypi
[1:43] * gbaman_ (~gbaman@ has joined #raspberrypi
[1:43] <sflw> I see. Something like this: https://www.youtube.com/watch?v=hsoggQOoG4s?
[1:44] <CoJaBo> I think most of the typical relay controllers designed for Pi can drive one of those, so the driver part shouldn't be hard.
[1:44] * calimero_82 (~fabiomirk@host105-138-dynamic.246-95-r.retail.telecomitalia.it) has left #raspberrypi

[1:57] <sflw> Okay, relay to solenoid. That's what I'll research then. Thanks!
[1:58] <Bilby> sflw, *relay driver* to solenoid... though you might actually need a relay to trigger it
[1:58] * _BigWings_ (~Thunderbi@modemcable119.79-19-135.mc.videotron.ca) Quit (Read error: Connection reset by peer)
[1:58] <Bilby> or a mosfet, at least
[1:59] <sflw> Bilby: Oh, that's an important clarification.
[1:59] <Bilby> I mean, you could physically use a relay to trigger a solenoid, but it's not really necessary
[2:00] <Bilby> you just need "x thing that can accept a low-voltage logic signal on one end and control the current of a solenoid on the other end"

[2:00] <mirana2s> raspbian default install, ~2.5GB. How come? How do I get rid of the bloat?
[2:00] <CoJaBo> Depends on the current/voltage of the thing; a tiny 12v one might be strong enough, unless it's a really small gong
[2:01] <Bilby> mirana2s, raspibian comes by default with a lot of packages. look at minibian for a minimal install
[2:02] <sflw> CoJaBo: I think it's relatively small.
[2:05] <mirana2s> df -h

[3:06] <ICantCook> I'm just thinking about the stability of running firefox 24/7 with no input
[3:06] <CoJaBo> Ah, it's not interactive then?

[4:04] <wiltors42> I've seen a few diy glasses that are 3D printed and use the iPhone/android
[4:04] <wiltors42> They get good resolution but I wanted to make something more standalone
[4:05] <wiltors42> Either way the pixels are magnified
[4:05] <biberao> wiltors42: ok ill be waiting :D
[4:05] <wiltors42> Nobody knows where to find really tiny high resolution displays? I saw a tiny micromirror display used in glasses once but it wasn't ever produced

[4:14] <Kamilion> wiltors42: last i saw, Meta was using these as their hack-aparts: http://www.epson.com/cgi-bin/Store/jsp/Product.do?sku=V11H560020

[4:15] * Macuser (~textual@unaffiliated/macuser) Quit (Client Quit)
[4:16] <Kamilion> wiltors42: yeah, they're still using the epson displays in their final: https://www.getameta.com/products
[4:16] <wiltors42> Cool, yeah looks like Epsom makes them for their projectors and stuff but it doesn't look like they sell the display modules
[4:16] <Kamilion> they do. just not individually.
[4:17] <wiltors42> Exactly
[4:17] <Kamilion> you'll get two from the glasses that are on the market right now.
[4:17] <wiltors42> I feel like at that point I would just use the glasses lol
[4:17] <Kamilion> and the little box they snap into contains a FPGA you'll have to reverse engineer.
[4:18] * Kamilion knew someone on the Meta team a while back
[4:18] <Kamilion> wiltors42: this is your other, preferable option: http://www.siliconmicrodisplay.com/st1080.html
[4:18] <Kamilion> they're not transparent, however.
[4:19] <Kamilion> and their devkit is a little steep at $8k: http://www.siliconmicrodisplay.com/ddk.html
[4:19] <wiltors42> Yeah but it's pretty costly. The LCD I got from adafruit was $60
[4:20] <Kamilion> oh, doing something like https://learn.adafruit.com/diy-wearable-pi-near-eye-kopin-video-glasses ?
[4:20] <wiltors42> Yes similar except I'm trying to make something more like an oculus rift
[4:21] * davor (~davor@unaffiliated/davor) Quit (Ping timeout: 264 seconds)
[4:21] <wiltors42> But I'm interested in making something more like the actual two display glasses set they're harvesting the displays out off
[4:21] <biberao> back
[4:22] <wiltors42> But my project uses lenses to magnify two images displayed sidebyside on a pretty low res LCD display in a dark box
[4:22] <Kamilion> oh, the rift uses a much larger LCD, some distorion lenses, and some shaders to provide anti-corrected distorted images the lenses will resolve.
[4:22] <Kamilion> http://www.4dsystems.com.au/product/uLCD_220RD_PI/
[4:23] <Kamilion> 4D system's LCD line would work for that
[4:23] <Kamilion> and I know a source to get ~4" to 5" cellular smartphone LCDs at 1080p and higher resolutions
[4:23] <wiltors42> Those are nice but the round ones are 220x220
[4:23] <wiltors42> Which is tiny
[4:23] <wiltors42> Interesting
[4:24] <wiltors42> I would want to interface it with hdmi
[4:24] <Kamilion> but the issue there is you'll run into problems trying to bitbang TMDS
[4:24] <Kamilion> and getting a HDMI/DVI to TMDS tranceiver is a little annoying
[4:24] <wiltors42> Maybe I just need to find a higher resolution 5" display
[4:25] <wiltors42> The adafruit part is really nice because it lets you plug right into the hdmi
[4:25] <Kamilion> http://www.adafruit.com/products/1716
[4:25] <Kamilion> adafruit had to design their own to adapt the ipad's 2048x1536 display
[4:26] * davor (~davor@unaffiliated/davor) has joined #raspberrypi
[4:26] <wiltors42> Oh that's for that huge iPad display
[4:26] <wiltors42> Nice
[4:27] <Kamilion> http://www.adafruit.com/categories/121
[4:27] <Kamilion> if you can find a display that's compatible with, it's your best bet.
[4:28] <ozzzy_> all displays are compatible... some you just may need to add some glue logic or write your own code for
[4:29] <Kamilion> https://www.youtube.com/watch?v=DIIjVSmbtFc Ben Heck has some FPGA code for driving some 'odd' resolution displays
[4:29] <Kamilion> the one he used came out of the back panel of a pinball machine
[4:30] <wiltors42> I wish I could get a tiny micromirror display
[4:30] * nirokato (niro@unaffiliated/nirokato) Quit (Ping timeout: 250 seconds)
[4:30] <Kamilion> yeah, DMDs are awesome.
[4:31] <Kamilion> but I'd definitely recommend having a look at that Ben Heck video to get some good ideas.
[4:31] <Kamilion> he found his 'wide' screen on ebay for 'car visors'
[4:31] <Kamilion> I've seen a few that are supposed to replace the rear view mirror
[4:31] <wiltors42> Yeah I've seen that actually
[4:32] <Kamilion> so if you look around chinasource sites like dx.com you could probably find a weird off-shape LCD fairly cheaply if you look in the right sections
[4:33] <Kamilion> I know there's a large range of high resolution displays from the manufacturers, they're used in plenty of cellphones.
[4:34] <Kamilion> and in general, you'll find they're either TMDS, TTL RGB, or LVDS.
[4:35] <ozzzy_> california is lucky
[4:36] <McBride36> except for like...idk water
[4:36] <Kamilion> What's wrong with our water? :<
[4:36] <Kamilion> It tastes fine to me...
[4:37] <ozzzy_> yeah... it's just fine here
[4:38] <Kamilion> besides, just another 15 years until the sun cools 0.02 percent for a while and we get another 'little ice age'.
[4:39] <wiltors42> What manufacturers exactly?
[4:39] <Kamilion> LG, Sharp, Sony, others.
[4:40] <Kamilion> the ipad panel is an LG, for instance.

[9:52] <tjcarter> I was playing around with Kano OS on my Pi 2 because it seems ideal for an 8yo I know… I noticed it uses kdesk instead of lxpanel, I'm wondering if anyone else found this to be more performance-happy otherwise. It's hard to tell with Kano OS because everything is so heavily curated there.
[9:53] <tjcarter> Also editing sessions in lxde that old isn't easy. ;)
[9:53] <alchemistswl> Never heard of Kano OS, just looked it up, seems sweet
[9:53] * duendecat (~duendecat@ Quit (Read error: Connection reset by peer)
[9:54] <tjcarter> alchemistswl: my major complaint with it is that it has a few bugs in the beta release you can just download regarding setting up accounts, and there are certain things I don't seem to have access to.
[9:56] <alchemistswl> hmm I see
[9:56] <tjcarter> For example, you get an automatic login on /dev/tty1. Okay, And on the other ttys are normal getty prompts. But the password we entered for the profile setup doesn't log in the user of the same name. Also the username is not in all lowercase, and you don't have the Raspbian nopasswd sudo access.
[9:57] <tjcarter> in other words, it gives you a child-locked account, or appears to.
[9:58] <alchemistswl> Okay I see, thats not really good then
[9:58] <tjcarter> Obviously when the kid outgrows the Kano OS, just install Raspbian.
[9:58] <tjcarter> It's also possible I did something wrong :)
[9:59] <tjcarter> I can just stick the TF card into a reader and modify the thing to have a normal passwd I guess
[9:59] <alchemistswl> I would for myself say that with 8yo I would have enjoyed having a normal PI
[9:59] <alchemistswl> I guess I would've fiddled around with it alot
[9:59] <alchemistswl> so why not

[10:00] <tawr> mostly arduino stuff
[10:00] <tjcarter> Yeah
[10:00] <tjcarter> The Kano Kit (US$150) is poo-pooed as too expensive, but I priced the contents of that kit separately and it's not THAT overpriced.
[10:01] <tjcarter> The major failing of the thing is that the keyboard is kiddie-sized.

[10:02] <tjcarter> I'm asking if that's what you're looking for.
[10:02] <alchemistswl> I think I heard something along those lines...
[10:02] <alchemistswl> yes
[10:03] <alchemistswl> There is scratch for Arduino

[10:04] <tjcarter> Or a variant of it anyway.
[10:05] <shiftplusone> wow... device tree + gpio_keys + systemd is awesome... just added proper power and reset buttons with a simple overlay, a udev rule and a slightly modified logind.conf
[10:07] <tjcarter> ah, but your power button shuts it off only ;)
[10:08] <tjcarter> Raspbian is kind of uncomfortable for me at the moment. It's too old for too many things, but jessie isn't really ready for prime time and I haven't really worked out enough of its development process yet to begin contributing anything.
[10:08] <shiftplusone> there's wake from halt functionality
[10:08] <shiftplusone> (which starts it back up)
[10:08] <tjcarter> nice
[10:09] <shiftplusone> I think if I put the poweroff on the same pin, it should work and the power off and power on switch
[10:09] <tjcarter> The other problem is that I'd need to go register an Ubuntu One account just to report the bug that the version of youtube-dl in Raspbian deletes itself and has remote code execution problems
[10:09] <shiftplusone> this will make a very simple, but cool tutorial, I think.
[10:10] <tjcarter> yeah it will
[10:10] <shiftplusone> Will save it for when the jessie image comes out
[10:11] * tjcarter still needs to find a good solution for his PiFace clock fitting on a pi with a heatsink
[10:11] <shiftplusone> easy... throw away the heatsink
[10:11] <shiftplusone> be careful not to damage the pi when peeling it off.
[10:12] <tjcarter> I found the heatsink DOES help if your case has some airflow potential
[10:12] <NedScott> helps what?
[10:12] <shiftplusone> but is it needed? what temperatures are you seeing and how much is it dropping?
[10:12] <NedScott> it can get pretty hot before that SoC has any issues :)
[10:12] <shiftplusone> I expect that you're dropping ~5 degrees max on a pi 2 (much less on a pi 1), but are nowhere near a temperature where you need to worry about it.
[10:13] <tjcarter> It's about 7-10 degrees under load
[10:13] <alchemistswl> Well my PI melted into the plastic after being on 100% for 8 hours or so (no overclock)
[10:13] <alchemistswl> nice smell
[10:13] <tjcarter> I have mine set to throttle at 75 degrees
[10:14] <alchemistswl> but it still works, so its fine
[10:14] * breakingmatter (~breakingm@ has joined #raspberrypi
[10:14] <shiftplusone> well... at least you seem to know a little of what you're doing. I've seen people claim their pi runs hot because it feels warm to touch and wack on a heatsink in a case with no airflow *facepalm*
[10:15] <tjcarter> Of course it's warm to the touch
[10:15] <shiftplusone> but yeah, the mantra among the engineers at raspberry pi is you don't need a heatsink.
[10:15] <tjcarter> I don't want it to get HOT to the touch

[10:15] <tjcarter> I dunno, I have had stability issues with ANY overclocking
[10:15] <tjcarter> or it could just be that videocore drivers are buggy :)
[10:16] * tjcarter suspects the buggy.
[10:16] <shiftplusone> that's not due to temperature, that's just due to the silicon you've happened to get. you can check the ring oscillator values and compare to values others are getting
[10:16] <shiftplusone> or it could be the power supply
[10:17] <tjcarter> the one issue I can't seem to fix is that if audio is set to HDMI, if I start playing audio, the beginning of the audio is cut off and the screen flashes black for about .5 sec
[10:17] <tjcarter> it flashes again when the sound stops playing.
[10:18] <tjcarter> And since raspbian's bluetooth is an antique, I found I could not get my BT keyboard and mouse to both work at boot at the same time, and I couldn't get my BT speaker to work at all. Eventually connected the speaker via an audio patch cable.

[10:21] <shiftplusone> that would be kind of an odd thing to do
[10:21] <shiftplusone> I wouldn't be able to help with this particular issue, that's why I recommend opening an issue on github (the relevant people look at those)
[10:21] <tjcarter> okay

[10:26] <BCMM> it's absolutely maddening that TVs have implemented the "overscan" concept with digital inputs
[10:27] <BCMM> like, that setting originally exists to fine-tune the electric potential on a deflector plate
[10:27] <shiftplusone> woo.... tried using the button as wake from halt as well.... now I have a proper power on, power off switch without any userland hackery.
[10:27] <BCMM> it is now meaningless
[10:27] <BCMM> shiftplusone: oh cool how does that work?
[10:28] <shiftplusone> BCMM: a device tree overlay to set a GPIO to KEY_POWER, which systemd handles
[10:29] <shiftplusone> systemd is configurable so you can make that power off, reboot, suspend or hibernate (and you can use multiple pins to do the different things)
[10:29] <BCMM> shiftplusone: and that powers *on* how?
[10:29] <shiftplusone> gpio 3 has wake from halt functionality on high to low transitions
[10:29] <shiftplusone> so if I use that gpio for power off, it doubles as power on
[10:29] * Berg (~chatzilla@pa114-72-179-121.pa.nsw.optusnet.com.au) has joined #raspberrypi
[10:30] <BCMM> is there a way to make it useful for power saving? iirc a powered off pi draws nearly as much current as an idle pi
[10:31] <shiftplusone> hmm? that's not what I've observed... let me double check.
[10:33] <BCMM> shiftplusone: there is a chance i'm talking rubbish
[10:34] * harish (~harish@ has joined #raspberrypi
[10:34] <shiftplusone> there's definitely current draw when halted, but it shouldn't be "nearly as much" as idle.
[10:34] <BCMM> also, if i did an actual test, it was on an original model B, and i know they have improved the regulators since then

[10:44] <Berg> i think to have it power off and then turn a relay off and a push buttion to restart the relay
[10:44] <Berg> im not entirely sure exactly what yet
[10:44] <shiftplusone> I'm surprised a halted pi 2 only uses 0.07A... partially suspect this meter thingy is not particularly accurate.
[10:45] <Berg> well i dont think it will draw much at all
[10:45] <shiftplusone> The old model b drew a lot. As BCMM said, almost as much as idle

[12:21] <shiftplusone> the red led should be good enough
[12:21] <shiftplusone> if you overclock and that's always on, without flickering, it's probably not a power issue.

[16:10] <joedu12> I've got a Raspberry Pi 2 with IR Camera module, and I want to stream the video to a webpage. I already know 3 methods but they all have many drawbacks.. One with raspivid + cvlc (the quality is fine but there is a lag of 6sec. and it's requires the VLC plugin on a webpage). One with raspistill and somme JS to refresh the image (the quality is fine, but max 2 FPS..) and one with PiStreamming (https://github.com/wavefor
[16:10] <joedu12> m80/pistreaming) but it's using a heavy js script witch is now working on safari (crappy Ipad..) and the quality is not very good. How can I stream in good quality from the raspberry to a webpage ?
[16:11] <azizLIGHT> A couple of hours ago, my Internet died and I had no way to know if it was a power outage or Internet outage
[16:12] <azizLIGHT> Couldn't ping my pi. Only reason I figured it was the Internet was because all my pc's on that network went offline in teamviewer
[16:13] <azizLIGHT> I need some kinda backup Internet, any good ideas?
[16:13] <IT_Sean> What's your budget for backup innernets?
[16:13] <azizLIGHT> Anything better than getting a T-Mobile lte tablet and using the free 200 mb data plan with a wifi hotspot for the pi?
[16:14] <IT_Sean> Again...
[16:14] <IT_Sean> What's your budget for backup innernets?
[16:14] <azizLIGHT> Maybe some kind of monthly lte plan for $40/MO or less
[16:14] <azizLIGHT> Or on demand usage plan?
[16:14] <azizLIGHT> Internet doesn't die often
[16:14] <IT_Sean> What's your primary innernet?
[16:15] <azizLIGHT> Brighthouse cable
[16:15] <azizLIGHT> Residential
[16:15] <IT_Sean> Get a cheap DSL connection, and fail over to that.
[16:15] <IT_Sean> Dunno about where you are, but, ehre, ATT DSL is around $15/mo for their slowest package
[16:15] <IT_Sean> it's TERRIBLE, but, as a backup, better than no connectivity at all
[16:16] <azizLIGHT> Does that need some kind of power supply of its own
[16:16] <IT_Sean> Well, yes, it would, for the modem.
[16:16] <azizLIGHT> Ah
[16:16] <IT_Sean> A small UPS would do.

[17:51] <stephanbuys> hi all, I'm wiring a LED to GPIO3 and upon bootup it looks like there is a failt amount of light coming from it. When I use the python script to set it to "False" though I can see its definitely 'off' and when I set it to true its definitely 'on', is there something I can do to make it not appear "somewhat on" on boot?

[17:53] <stephanbuys> no, just the plain LED
[17:53] <SpeedEvil> You need a resistor or you may damage the Pi.
[17:54] <SpeedEvil> Try a 100 ohm to 1K resistor in series with the LED, and a 10K resistor across the LED to absorb the small current from the pin set to 'weak pullup'
[17:54] <stephanbuys> SpeedEvil: oh my thanks, is there a reference somewhere that gives these numbers?
[17:55] <SpeedEvil> They were random numbers as a sensible guess. ##electronics - sorry AFK

[19:56] <DoctorD90> shutdown i remember it didnt work xD a search and halt find/workz
[19:57] <joedu12> do anyone has tried uv4l-webrtc ?
[19:57] <Kamilion> shutdown normally does a telinit, asking init to go to runlevel 6 or 0 depending on -h or -r, init will then sanely shut down services and invoke 'halt' at the end. normally, that will make an APM or ACPI call to disable board power on an ATX/PC system.
[19:57] <DoctorD90> so i have to use shutdown -r ...ok!
[19:57] <ShorTie> just 'shutdown' is incomplete
[19:57] <Kamilion> in systemd, things are a little different
[19:57] <Kamilion> IIRC shutdown now makes a dbus call to systemd
[19:58] <Kamilion> but reguardless, at the end, the 'halt' binary is usually what cuts the power on most systems.
[19:58] <Kamilion> or does the final transition into some kind of a low power state.
[19:59] <Kamilion> in some cases, like the pi, asking it to halt simply puts the CPU into a nop loop with no recovery.
[19:59] <Kamilion> in that state, no I/O will be performed, so it's safe to remove power.
[19:59] <Kamilion> the major factor, however, is umounting the disk before poweroff
[20:00] <ShorTie> yup.
[20:00] <Kamilion> init or systemd's supposed to do that so the filesystem is marked 'clean' for the next boot up.
[20:00] <Kamilion> otherwise it tries to do filesystem checks and that takes forever

[20:02] <ShorTie> on some distros is the key, it's not the same on all so that is why it is best to know the real command
[20:02] <DoctorD90> so shutdown -h now....good!
[20:02] <ShorTie> Yes
[20:02] <Kamilion> in almost all cases, 'shutdown -h now' will work.
[20:03] <DoctorD90> thx :D
[20:03] <Kamilion> I've not found many systems other than REALLY deeply embedded shrunken tiny systems that only have 'halt'.
[20:03] <Kamilion> which seems to be a very tiny binary that calls either a NOP loop or the HLT instruction if it's supported.
[20:04] <Kamilion> likewise, i still recommend using the 'service' binding for now instead of invoking systemctl directly.
[20:04] <Kamilion> because doing it through 'service' will work on a great majority of distros, running systemd or not.
[20:04] <ppq> some embedded systems don't even have halt. you just cut the power, or reset it for reboot

[20:29] <ShorTie> but your not being nice, imho, by promoting the compatition
[20:29] <Kamilion> now, it could be argued this discussion could be construed as not abiding the instruction of the channel staff.

[20:31] <Kamilion> Okay, then you can deop and I can shut up.
[20:31] <breakingmatter> I dont' really have a horse in this race, but I don't personally see any issue in comparing the RPI to another board. THey all offer different things; sometimes its nice to determine what the differences are.
[20:32] <breakingmatter> Let them eat cake.
[20:32] <Kamilion> Either way, it's not wise for either party to press the issue.
[20:32] <SyncYourDogmas> Eh I'm the opposite. Id rather discussion stuck to all things pi

[20:36] <Kamilion> Does anyone have any experience with the RASPBERRY PI FOUNDATION's github kernel package supporting the AXIS AX88772A USB to ethernet chip?
[20:37] <breakingmatter> SyncYourDogmas: The .tar.gz is 258MB if that's what you mean.
[20:37] <ShorTie> like any minimal installs, it is small
[20:37] <Kamilion> I've had bad experiences with AXIS support in the past.
[20:37] <breakingmatter> SyncYourDogmas: It's incredibly bleeding edge, so you have to deal with occasional instability.
[20:38] <Kamilion> more specifically, do I have to do anything specific to switch the OTG mode so it's not attempting to provide power?
[20:38] <breakingmatter> That, and they don't release an img

[20:40] <Kamilion> breakingmatter: so the pi's micro port does not deliver power, even when the pi is powered via the GPIO header?
[20:40] <breakingmatter> Kamilion: Oh, I see what you're saying then. I've never powered it through the GPIO header

[20:40] <SyncYourDogmas> Cheers *
[20:40] <Kamilion> IE, it's only in OTG data mode and lacks the buck/boost of a normal OTG board design on a mobile device?
[20:41] <Kamilion> I'm looking closely at the pi2's power regulation section
[20:41] <Kamilion> but i'm not seeing evidence that it can provide power to the micro port.
[20:41] <breakingmatter> Kamilion: Yeah, you're starting to venture outside the realm of my experience.

[20:44] * DLSteve (~DLSteve@c-24-30-90-21.hsd1.ga.comcast.net) has joined #raspberrypi
[20:44] <breakingmatter> Why not just use the USB controllers?
[20:44] <Kamilion> Cool. okay. So it won't hurt anything if I mess around with some diodes and force the power.
[20:44] <Kamilion> breakingmatter: I already have four devices plugged in
[20:44] <Kamilion> logitech unifying tranceiver, a bluetooth sniffer, two USB to serial adapters.
[20:45] <breakingmatter> The RPI has a hard time powering a separate device. It's usually recommended to plug anything that needs power into a powered hub
[20:45] <Kamilion> and I wanted a second ethernet port so i could mess with iptables.
[20:45] <breakingmatter> I usually can't use more than one usb flash drive at a time
[20:45] <Kamilion> I've already swapped one of the USB to serial adapters for a USB2.0 to fast ethernet adapter
[20:45] <Kamilion> they're all USB-low-power spec devices drawing under 100ma
[20:46] <Kamilion> at least, that's what their USB descriptors say
[20:46] <Kamilion> the logitech unifying receiver may draw a little more during transmission.
[20:46] <breakingmatter> But the USB pwoer for the pi itself only provides ~800-1000ma
[20:46] <SyncYourDogmas> Ive got teo powered usb hubs that I need for anything I do pretty much
[20:46] <Kamilion> yeah, which is why, if I plug in a powered hub, I'd rather there just be one power lead going right to the hub.
[20:46] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[20:47] <Kamilion> i get three more USB ports I can hard mount the usb to serial adapters on, and no more twin-ethernet woes
[20:47] <Kamilion> the second ethernet port connects to the SWANN network video recorder.
[20:47] <breakingmatter> Kamilion: The rpi2 uses between 250 and 350ma depending on what's going on
[20:47] <Kamilion> any idea what that draw is while underclocked to 500mhz?
[20:48] <Kamilion> and can it be undervolted safely now that the DRAM has been separated from the CPU package's regulators?
[20:48] <breakingmatter> I would imagine probably in the 200-220ma area.
[20:48] <Kamilion> so not by much
[20:48] <breakingmatter> Under heavy load, it can pull 500ma easily
[20:48] <Kamilion> does it support power governors like ondemand, and clock scaling, or is it always at it's stock 700mhz across all four cores?
[20:49] <Kamilion> how do the cores sleep? do they sleep? or just HLT or NOP loop?
[20:49] <Kamilion> I have burning questions... XD
[20:49] <breakingmatter> The only way to change the default governor is to recompile the kernel
[20:49] <Kamilion> also, I've seen people with little heatsinks and tiny fans -- where the heck do you find them?
[20:50] <breakingmatter> But you could always make a script on startup to change the scaling
[20:50] <breakingmatter> Kamilion: supports conservative ondemand userspace powersave performance
[20:50] <Kamilion> I just got my pi2 on friday, so i'm kind of trying to get up to speed quickly.
[20:50] <breakingmatter> I don't know how the cores sleep
[20:51] <Kamilion> never had a foundation built BCM before now, which is why I've been silent despite being in here for over a year now.
[20:51] <Kamilion> appears I had good reason to lurk :/

[20:51] <Kamilion> anyway, sorry.
[20:51] <Kamilion> Good info, thanks much.
[20:52] <Kamilion> what's the default govenor?
[20:52] <Kamilion> ondemand?
[20:52] <breakingmatter> Kamilion: Yes, ondemand
[20:52] <Kamilion> k, if that's so, i can take a wild guess and say it does support frequency scaling

[20:53] <Kamilion> maybe not dynamic voltage scaling, but I can live without that.
[20:53] <breakingmatter> You can check the current governor with `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors`
[20:53] <Kamilion> yeah, I just didn't have it plugged in right now

[20:54] <Kamilion> http://centralcomputers.com/p-233876-hdmi-a-m-to-vga-f-adapterwhiteproduct.aspx
[20:54] <Kamilion> bought it locally when i got my pi
[20:54] <breakingmatter> I don't see how that's possible.
[20:55] <breakingmatter> Usually have to convert digital to analog.
[20:55] <breakingmatter> i.e., powered converter
[20:55] * breakingmatter shrug
[20:55] <Kamilion> there's a chip inside, powered by the hdmi port.
[20:55] <breakingmatter> ah
[20:55] <breakingmatter> Science
[20:55] <Kamilion> gets +5v due to the DDC rom chip containing the EDID modes.
[20:55] <Kamilion> yay autodetection.
[20:56] <Kamilion> anyway, I was reading config.txt and it seemed to indicate I needed to set a couple variables like the HDMI drive mode, and lock it into a specific resolution up front.
[20:56] <breakingmatter> Yeah, I dont' have much experience with setting it up with a monitor
[20:56] <Kamilion> this is a little 14" dell VGA LCD, 1024x768, I've had it working on 'other' BCM devices.

[21:19] <Kamilion> if you try on a pi1, eh, I dunno. Might be some patches for armv6, might not, never done it, but I know people *have* done it.

[21:36] <Kamilion> no
[21:37] <Kamilion> only ownership is

[21:37] <Kamilion> the permissions should have already been 0644

[21:37] <Kamilion> it may have more to do with the group that sftp has assigned
[21:37] <Kamilion> or not assigned
[21:37] <nath_> ok right
[21:37] <Kamilion> what's it's primary gid?
[21:38] <Kamilion> if you type 'id', what's the response of the group memberships?
[21:38] <Kamilion> (as the sftp user, you may have to su - sftp beforehand)
[21:38] <nath_> uid=1001(sftp) gid=1004(sftp) Gruppen=1004(sftp)
[21:39] <Kamilion> okay, so it has it's own group
[21:39] <Kamilion> oh, you said it can access other's files
[21:39] <Kamilion> yes, that's correct
[21:39] <nath_> well if I login via SSH
[21:39] <Kamilion> if you want to sheild the other user's home directories, you'll want to change the permissions of 'group' and 'other' to 0
[21:39] <Kamilion> but you can't really do that to the rest of the system without causing breakage
[21:39] <nath_> ok right thats what I want

[21:40] <Encrypt> nath_, If you're trying to restein user privileges
[21:40] * darkbasic (~quassel@niko.linuxsystems.it) Quit (Ping timeout: 240 seconds)
[21:40] <Encrypt> You could also do an SSH jail
[21:40] <Kamilion> right, so in that case, you'd want to do something like chmod o-r /home/*; chmod g-r /home/*; chmod g+r /home/sftp; chmod o+r /home/sftp;
[21:41] <Encrypt> restrain*
[21:41] <Kamilion> if you wanted /home/sftp to be the directory shared by the other accounts.
[21:41] <nath_> Kamilion: no I dont want to share any
[21:41] <Kamilion> then you can leave off the latter two commands
[21:41] <Kamilion> chmod o-r /home/*; chmod g-r /home/*; should do the trick.
[21:42] <Kamilion> keep in mind, root will still be able poke in there
[21:42] <nath_> all I want is when sftp loggs in, I don't want it to be able to access pi's files
[21:42] <Kamilion> sftp isn't a member of the pi group
[21:42] <Kamilion> so it's treated as 'other'
[21:43] * hyperair (~hyperair@ubuntu/member/hyperair) Quit (Ping timeout: 246 seconds)
[21:43] <Kamilion> also, if you define mounts elsewhere in the filesystem like in /media or /mnt, you'll also want to set proper permissions and ownership there.

[21:44] <nath_> Kamilion: ok I feel a little to green for this, at least I managed to login from outside to my Raspby on this account
[21:44] <Kamilion> Alternatively, depending on the guest operating system accessing your pi, you may be more interested in installing samba4 and using the windows sharing tools to define fine-grained access control lists.
[21:44] <nath_> I think I need to do some further reading...

[21:45] <Encrypt> nath_, An SSH jail!
[21:45] <Kamilion> yeah, ssh jails can also work
[21:45] <Encrypt> nath_, This will solve your problem super nicely
[21:45] <Kamilion> look at openssh's configuration files
[21:45] <nath_> Encrypt: ok I'll check for this
[21:45] <Kamilion> it can be harder to set up though
[21:45] <Encrypt> Without changing the group
[21:45] <Kamilion> and it's always a good idea to know how unix permissions work.
[21:45] <Encrypt> nath_, Basically, it defines the root folder of a user
[21:45] <nath_> Encrypt: ok nice
[21:45] <Encrypt> You can say something like: "The root folder is /home/sftp"
[21:46] <Kamilion> Encrypt: can you provide him a snippet to paste in /etc/ssh/sshd_config ?
[21:46] <Encrypt> So, when the user logs in
[21:46] <Kamilion> or perhaps /home/sftp/.ssh/config ?
[21:46] <Encrypt> He or she can not go down in the filesystem
[21:46] <Encrypt> Hum :D
[21:46] <Encrypt> We learnt that in class
[21:46] <nath_> Encrypt: nice thats what I want to go for

[22:20] <Kamilion> honestly, I like OpenSSH's Tun/TAP VPN the best, but there's not a working MS windows client to my knowledge
[22:21] <Kamilion> in layer 2 mode, it's honestly the most painless VPN system ever, since it works on most openssh 6.4+ hosts that don't disable it in the config files (and support for it is enabled by default in debian and ubuntu, IIRC)
[22:21] * Sisco (~Sisco@unaffiliated/sisco) Quit (Ping timeout: 244 seconds)
[22:21] <Kamilion> there's also things like hamachi and ngrok
[22:22] <Kamilion> as to how trustworthy they are, I dunno.
[22:22] <Kamilion> but my vote goes to OpenSSH's TCP based TAP VPN, or openvpn's UDP based TAP VPN if you're dealing more with UDP traffic than TCP.
[22:23] <Kamilion> there's also solutions like openvswitch's GRE tunneling
[22:23] <Kamilion> and VXLANS
[22:24] * rwb (~Thunderbi@host55.vsac.cust.sover.net) Quit (Quit: rwb)
[22:25] <SyncYourDogmas> I'm gonna running this on the pi. There's a vpn using ssh? Gre tunnelling is more for isps traffic management, I'm interested in security /anonymity. Thanks for all the suggestions, I'll look into them
[22:25] <Kamilion> Apocx: I've done so by convincing an old android device to act as an RNDIS USB Ethernet Class device. I think it was a samsung galaxy mini or something, android 2.3.3 IIRC
[22:25] <Kamilion> GRE tunneling is actually used a lot more now that software defined networking has become big buisness.
[22:26] <Kamilion> and it's definitely preferential to a MS solution like PPTP
[22:26] <Kamilion> you can most certainly run openvswitch on your pi
[22:26] <Kamilion> and I'd figure it'd be good for about 40-50Mbit.
[22:26] * dozn (~dozn@ Quit (Read error: Connection reset by peer)
[22:28] <Kamilion> more if you used a second USB to ethernet interface like an ASIX gigabit USB 3.0 tranceiver in USB 2.0 mode. You'll get a 1000mbit link rate, but you'll only have approximately 330Mbit available for ethernet framing over the USB 2.0 fallback of 480Mbit.
[22:28] <SyncYourDogmas> Kamilion: i know all about sdn, I want a break from it :) masters project is sdn for lte. yeah openvpn I'm definitely including. Unfortunately not able to test upper bandwidth bounds that high. Maybe on my lan.
[22:29] <Kamilion> Still quite more than enough -- the biggest stumbling block is the original pi's USB 2.0 controller requiring a LOT of CPU interrupt time, up to 40-50% of the single core 700Mhz.
[22:29] <Kamilion> the Pi2 resolves that nicely simply due to having four cores that can share the interrupt load.
[22:29] <Kamilion> or at least, one of the cores is specifically hooked to a number of hardware interrupts, either core 3 or core 0. Not sure which
[22:30] <SyncYourDogmas> Was there no dma on the first pi? Or second for that matter
[22:30] <Kamilion> The KVM hypervisor instructions seem to point at core3 being the one to isolate from VMs
[22:30] <Kamilion> it has a DMA controller, but not an interrupt router.
[22:30] <Kamilion> the ethernet is also provided by a USB to ethernet adapter, and sending small URBs over the USB bus can be stressful on interrupt usage.
[22:31] * r00t66 (~r00t66@ has joined #raspberrypi
[22:32] <SyncYourDogmas> I thought the point of dma was to only interrupt when it has filled the buffer etc. Yeah I've heard of that usb limitation
[22:33] <Kamilion> well, it depends on how you're making use of the DMA controller, and if the code you have loaded is using it efficiently or not
[22:33] <Kamilion> I mean, you may have a 32bit DMA controller and be telling it to do short 8-bit reads
[22:33] <Kamilion> so right there you'd lose 3/4ths of your available bandwidth
[22:34] <Kamilion> and there's still quite a bit of devices that use memory mapped IO or PIO resources with very short transfers
[22:34] <Kamilion> the AHCI disk controller in most wintel machines is a good example.
[22:35] <Kamilion> There's also a range of functionality available from DMA controllers.
[22:35] <Kamilion> some act on simple lists, some support full scatter/gather in hardware.
[22:36] <SyncYourDogmas> Hmm true, I'm not sure whether to use tools like iperf or do socket programming myself
[22:36] <Kamilion> honestly, i stick to python until it's too slow, then rewrite that function in C and load it through FFI or ctypes.
[22:37] <Kamilion> and make use of as many C extensions as I can, like scrypt and uwsgi.
[22:38] <Kamilion> the less work i have to do, the more time I can spend learning more tools
[22:38] <SyncYourDogmas> The python sockets library is basically a thin wrapper on top of the c one, I'd be using that. And python for this test
[22:38] <Kamilion> and mapping them to how I've used previous tools, then selecting the opinionated 'best'.
[22:39] <Kamilion> yep. Python3's asyncio has a very nice event system that makes dealing with sockets a lot less messy, re: covering corner cases
