[13:51] <dreamreal> Grievre: heh
[13:51] <gordonDrogon> yea, maybe the $35 budget was just cutting it a bit too fine...
[13:52] <dreamreal> well, personally, I'm thrilled with the pi - $50 is a higher emotional cost than $35
[13:52] <Manei> Grievre: It can be over anything I guess
[13:52] <gordonDrogon> the beaglebone black have also had a year to study & learn ...
[13:52] * MidnighToker (~Toker@unaffiliated/midnightoker) has joined #raspberrypi
[13:52] <dreamreal> $35 is casual investment, $50 is "hey, what am I buying?"
[13:52] -NickServ- MABot!~datagutt@static. has just authenticated as you (DataBot)
[13:52] <Triffid_Hunter> ShadowJK: yeah that's why I put mlcc on the usb ports
[13:52] <Manei> I have a wifi adapter on my pi and I wish to use an xbox controller to control the pins from a different computer.
[13:52] <Grievre> Manei: That's gonna be slow and/or unreliable
[13:52] <Grievre> gordonDrogon: To learn what though?
[13:52] * Delboy (~openwrt@2001:b68:fc00:8b08::1) has joined #raspberrypi
[13:52] <dreamreal> Grievre: what worked with the pi and what didn't
[13:53] <Triffid_Hunter> Manei: why not just plug it straight in? they're plain usb with a different connector as far as I know
[13:53] <ShadowJK> Well, phone chargers are *supposed* to lower the voltage when the load increases, to hint to phones what acceptable charging current is..
[13:53] <Manei> Triffid_Hunter: Because the project I am working on requires the xbox controller to be on a different computer
[13:53] <Manei> It would kinda defeat the purpose if it was plugged into the pi
[13:53] * hyperair (~hyperair@ubuntu/member/hyperair) Quit (Ping timeout: 256 seconds)
[13:53] <Grievre> Dreamingpup: ?
[13:54] <Grievre> er
[13:54] <Grievre> dreamreal: ?
[13:54] <Triffid_Hunter> Manei: ah. you'll need to whip something up for that then.. perhaps something that reads /dev/input/eventN or whichever node your controller gets, digests the data and sends something useful over the network
[13:54] <dreamreal> Grievre: beaglebone gets to see what people liked about the pi
[13:54] <Grievre> ah yeah
[13:54] <ozzzy> I'm using a Pi as an 'arduino on steroids'... I don't really need a beaglebone
[13:54] <Manei> Well, I don't understand that much about linux...
[13:55] <Grievre> ozzy: The Pi is only an "arduino on steroids" if you put something other than linux on it
[13:55] <ozzzy> the OS is just plumbing
[13:55] <Grievre> otherwise the arduino actually beats it in several key categories
[13:55] <ozzzy> for my needs debian is just fine
[13:55] <Grievre> sure
[13:55] <ReggieUK> they're different devices doing different things
[13:55] * ShadowJK uses arduino as I/O board for his PCs and Pis
[13:56] <ReggieUK> you can interface to all of the ICs and sensors the same as on an arduino
[13:56] <Tachyon`> the only real disadvantage of pi/linux is the lack of a real time kernel
[13:56] <Grievre> I wonder if you can get PCIe GPIO cards
[13:56] <ReggieUK> Tachyon`, agreed
[13:57] <Grievre> There are a lot of projects where I want real-time, but I don't want to rewrite support for things like filesystems from scratch
[13:57] <Grievre> which has me a bit torn
[13:57] <Grievre> linux has the best collection of drivers of any open source OS
[13:57] <Grievre> but it's not realtime
[13:57] <ShadowJK> realtime is hard
[13:57] <Triffid_Hunter> Grievre: last time I checked, linux supports more devices "out of the box" than any OS ever
[13:57] <ReggieUK> it really needs a groundswell of interest to get it going
[13:57] <Grievre> ShadowJK: It's easy if the number of devices you're talking to and the number of threads you're running are both relatively low
[13:58] <Grievre> ShadowJK: it gets hard when you have a dozen or two peripherals and hundreds of processes
[13:58] <Manei> Triffid_Hunter: How about if I shared my phones network with my pi and had a web based interface?
[13:58] * GentileBen (GentileBen@cpc5-lutn10-2-0-cust681.9-3.cable.virginmedia.com) has joined #raspberrypi
[13:58] <Manei> Forget the xbox controller
[13:58] <Manei> And just have buttons
[13:59] <Triffid_Hunter> Manei: sure. latency may be high, make sure your application can handle some
[14:00] <Grievre> Manei: Wifi has significant packet loss even in best-case scenarios
[14:00] <Grievre> So you may find yourself disappointed with any solution you come up with
[14:00] <ozzzy> so far I've written my astro apps for the pi in bash... but I think I'll redo them in perl
[14:00] <Manei> High latency is fine.
[14:00] <Triffid_Hunter> Manei: for best results, use websockets or similar.. that will at least get rid of the setup/exchange/teardown delays for regular ajax or cgi calls
[14:00] <Manei> Do you know any tutorials or references for these?
[14:01] <Triffid_Hunter> Manei: just what google brings up
[14:01] * hyperair (~hyperair@ubuntu/member/hyperair) has joined #raspberrypi
[14:01] <Triffid_Hunter> Manei: websocket is basically a persistent, bidirectional ajax call that's set up using a standard http request
[14:01] <Manei> http://www.instructables.com/id/Web-Control-of-Raspberry-Pi-GPIO/
[14:01] <Manei> Um...
[14:02] * bizarro_1 (~bizarro_1@ has joined #raspberrypi
[14:02] <Grievre> Triffid_Hunter: Well whether it's "out of the box" or not is just the fact that they decided to just absorb every open-source driver into the kernel source tree. What's important is not that it comes with the drivers, but that (with some exceptions) most linux distributions are designed to be hardware-agnostic from boot
[14:02] <Grievre> Triffid_Hunter: On multiple occasions I've pulled a hard drive from a machine running linux, put it into an entirely different machine and it booted right up and ran just fine
[14:02] <Triffid_Hunter> Grievre: concur completely, hardware agnostic livecds are awesome :)
[14:02] <Grievre> Windows don't do that
[14:03] <Manei> Grievre: I did it with windows twice
[14:03] * Cy-Gor (~Brian@cpe-70-124-70-140.austin.res.rr.com) has joined #raspberrypi
[14:03] <Triffid_Hunter> heh nope, windows has a complete conniption if you try
[14:03] * divine (~divine@2001:470:8247:1::42) Quit (Read error: Operation timed out)
[14:03] <Manei> I just needed new drivers
[14:03] <Manei> Booted up and ran on it for 6 months
[14:03] <Grievre> Manei: Well windows has gotten better about it yes, but it's definitely not designed for it, and after you do it a few times weird things start to happen
[14:04] <Triffid_Hunter> meh windows needs to be reinstalled from scratch every 6 months anyway, last time I checked
[14:04] <Grievre> At least it fixed the major issue in windows XP which was if you move from an Intel processor to an AMD one it will just bluescreen on boot
[14:04] <Grievre> unless you disable intelppm beforehand
[14:07] <ShadowJK> they did have that windows update go out that made windows bluescreen on boot for many amd computers :)
[14:07] <ShadowJK> because the manufacturer had taken a "include all drivers" approach
[14:07] <gordonDrogon> Grievre, there are loads of ISA/PCI IO cards - I've no reason to think there aren't PCIe versions.
[14:07] <gordonDrogon> Grievre, how 'realtime' do you need?
[14:08] <Grievre> gordonDrogon: well like you can't bitbang protocols on the raspberry pi that have timing constraints
[14:09] <Tachyon`> PIC/AVR in the middle and you can, but aye -.o
[14:09] * cccyRegeaneWolfe is now known as cccyRegeane_Away
[14:10] <Grievre> right I'm saying that there are a lot of projects for which I feel like a single-chip solution is right but using two chips would make the software part easier
[14:10] <Grievre> except for the beaglebone
[14:11] <ShadowJK> you can do realtime on bbb?
[14:12] <Triffid_Hunter> ShadowJK: it has a micro core alongside the app processor
[14:13] <Grievre> two of them actually. And they share memory (some of it anyway)
[14:13] * user82 (~user82@unaffiliated/user82) has joined #raspberrypi
[14:13] <Grievre> so you can move data back and forth from your realtime code to your linux system without having to use a serial protocol
[14:15] <gordonDrogon> Grievre, sure, but I'd be wary of doing that on a 'PC' too - or anything with dynamic RAM really.
[14:15] <Grievre> ?
[14:16] <Grievre> why
[14:16] <gordonDrogon> dram refresh has the potential to stall the processor.
[14:16] <Grievre> oh you mean bitbanging
[14:16] * LWK (~LWK@mjhosting.co.uk) Quit (Excess Flood)
[14:16] <gordonDrogon> anything needing softwaretiming loops.
[14:17] <gordonDrogon> you can "get away" with a lot on the Pi though, but it all depends on just how "real time" you need. e.g. car engine control - nope, but simple slow robots seem fine. someone has even gotten a balancing robot going on the Pi and a quadcopter and I really didn't think it would be stable enough for that.
[14:18] * LWK (~LWK@pdpc/supporter/student/lwk) has joined #raspberrypi
[14:19] <ShadowJK> SMIs are a bigger issue on PCs than cache and dram issues
[14:19] <Grievre> SMI?
[14:19] <ShadowJK> system management interrupt
[14:19] <Tachyon`> think risc os is real time...
[14:20] <Tachyon`> but not sure if you have GPIO access in that
[14:20] <gordonDrogon> risc os - it's co-operative multi-tasking.
[14:20] <dreamon> running apache2 & php5.x on rpi. C program is runing and I want to send from over php a exec("pkill -USR1 -x heizpi"); -> USR1 Signal to my "heipi" program. but the signal is not being received because "heizpi" had to runned as root. what can I do?
[14:20] <gordonDrogon> so if you don't "give up" control, then you get to keep it.
[14:21] <gordonDrogon> however I don't know what happens with interrupts - e.g. if you ping it via Ethernet, etc.
[14:21] <bertrik> I think I got bitten once by SMI, was unexplicably losing time in VxWorks, disabling "usb-legacy support" in the bios fixed it
[14:21] <gordonDrogon> and you still have the underlying gpu/dram issue.
[14:21] <Tachyon`> gordonDrogon, you dont' have to multitask at all in risc os
[14:21] <Tachyon`> you can boot into supervisor or bbc basic
[14:21] <Tachyon`> then all the cpu is for your process
[14:21] <gordonDrogon> apart from the gpu which takes over memory refresh..
[14:22] <Tachyon`> oh bollocks, didn't think of that
[14:22] <Tachyon`> oh well, was a nice idea while it lasted, lol
[14:22] <Grievre> gordonDrogon: well what's the longest possible amount of time DRAM could stall the CPU for? Set your timer interrupt to fire that long (or longer) in advance of the time you want your thing to happen, then when it fires, spinlock until it's actually time to do your thing... this is assuming that the issue is just precision. If you also need to do these things really fast, well then you're
[14:22] <Grievre> out of luck
[14:22] <ShadowJK> Well it's also hw drivers and interrupt handlers that need special attention.. even on linux you get realtime priority over other multitasking processes if you ask for it, and are then limited by interrupt handlers and drivers stealing cpu away
[14:23] <gordonDrogon> Grievre, I think it's easier to use a dedicated microcontroller for the really tight stuff.
[14:23] <gordonDrogon> e.g. I'm doing some stepper motor stuff now - where I have an ATmega controlling a number of steppers with sub 100?S pulsing going to them...
[14:24] <Manei> Ok, so I'm going to follow tghis tutoprial
[14:24] <Manei> http://www.instructables.com/id/Web-Control-of-Raspberry-Pi-GPIO/
[14:24] <Tachyon`> I think the BBC ran the bus at twice the speed and interleaved video/cpu access
[14:24] <gordonDrogon> I can do it on the Pi, but it's littery - to the point where a stepper will stall when being driving at high speed.
[14:24] <Tachyon`> at least I had no timing problems on that system, heh
[14:24] * satellit_e (~satellit@ has joined #raspberrypi
[14:24] <ShadowJK> I did wonder if that blasted gpu wouldn't interfere.. too bad there's no "Off" switch :(
[14:24] <gordonDrogon> Tachyon`, yes - both the Apple II and BBC did that - so the dram refresh and video access happened on the opposite clock cycle.
[14:25] <gordonDrogon> My aim is to work with Linux - there are many advantages to using it - e.g. a filing system, network access, but it limits the realtimeness of it all, but for the most part it's understandable and can be worked with - just need to know the limits.
[14:26] <Grievre> gordonDrogon: hehe in my senior design project, we had to design a video interface that would fetch data from ram fast enough to never lose sync no matter how heavy the CPU was working. The CPU had higher priority on the RAM than your video interface, but was guaranteed to only make a request every other cycle
[14:26] * Jevermeister (~Jevermeis@unaffiliated/jever) Quit (Ping timeout: 248 seconds)
[14:26] <Grievre> so as long as you spammed your requests as fast as you could you were okay
[14:26] <gordonDrogon> e.g. my softwarePWM/Tone code - works really well - for what it does.
[14:26] <Grievre> gordonDrogon: in retrospect I wish I'd just modified the memory arbiter to prioritize the pixelfeeder
[14:27] <Triffid_Hunter> dreamon: why does your program need to run as root?
[14:27] <gordonDrogon> Grievre, I remember way back using some dual-ported DRAM for video boards - stupidly expensive, but I wasn't the designer..
[14:27] <Triffid_Hunter> dreamon: usually for stuff like that you can create a unix socket in /var somewhere, set appropriate perms and stuff data into it from your php
[14:27] <Grievre> gordonDrogon: I wonder if dual-port DRAM is actually worth it vs getting single-port DRAM that's twice as fast... but then again SDRAM isn't actually random access
[14:27] * gshrikant (~gshrikant@ has joined #raspberrypi
[14:28] <Grievre> (multiple accesses to the same row are faster than to different rows)
[14:28] <dreamon> Triffid_Hunter, wiringPi:-> Must be root to call wiringPiSetup().
[14:29] <gordonDrogon> Grievre, this was 23ish years ago ... seemd like the best idea at the time... I jsut wrote the code for the video sequencer on those boards...
[14:29] <Grievre> just give yourself permissions on whatever device files wiringpi has to use
[14:29] <Grievre> I mean it's just the GPIO pins right?
[14:29] <Grievre> RIGHT?
[14:29] <gordonDrogon> Grievre, sadly not.
[14:29] <gordonDrogon> Grievre, do you own a Pi?
[14:29] <Grievre> I have two
[14:29] <Grievre> or rather I own one, the other was used for a project
[14:29] * Thra11 (~Thra11@ Quit (Quit: WeeChat 0.4.0)
[14:29] <gordonDrogon> wiringPi uses /dev/mem - and giving that world read/write is not generally a good idea.
[14:30] <Grievre> Well yeah but using /dev/mem is also not generally a good idea
[14:30] <gordonDrogon> it can use /sys/class/gpio/* but it's rather slow.
[14:30] <Tachyon`> haha
[14:30] <Tachyon`> understatement of the year
[14:31] <dreamon> Triffid_Hunter, Thats not the problem to store data. the problem is only so send a signal as root.

[14:31] <gordonDrogon> dreamon, make your CGI program set-uid root, then you can make it drop root priviliedges when you need to write files.
[14:32] <dreamon> Triffid_Hunter, I never tried..
[14:32] <Grievre> could you not also just make the program that does wiringpi stuff drop root after setting up the wiring stuff?
[14:33] <gordonDrogon> Grievre, wiringPi is a library - it would be up to the calling program to do that.
[14:33] <dreamon> gordonDrogon, I dont want to write a file. Only send a simple signal flag like -> pkill -USR1 -x heizpi -> That works fine (if I start as root) but from php thats a problem because of lower rights.
[14:34] <gordonDrogon> dreamon, so make the CGI program setuid root.

[14:34] <Triffid_Hunter> dreamon: ooh I know, you want a setsid binary that sends the signal for you
[14:35] <gordonDrogon> anyway, mug of tea time now I think.
[14:35] <Triffid_Hunter> dreamon: so make a simple C prog that sends your signal, then compile and chmod u+s the binary.. not sure if setsid works with bash scripts, experimentation required

[15:59] <Bushmills> esing: those images contain partitions. they are, by copying them to sd-card, replicated the same size as in the image
[16:00] <esing> gordonDrogon, Bushmills Thanks, makes sense now. So if I wanted to use the total space of my sd-card I'd need to ssh to my openelac system and resize it or create a home partition and adjust the fstab in the root partition
[16:03] * Delboy (~openwrt@2001:b68:fc00:8b08::1) has joined #raspberrypi
[16:03] <gordonDrogon> esing, yes. easy to just run sudo raspi-config (or is it rasp-conf, I forget)
[16:03] <Bushmills> resizing involves two steps: tell partition table where partition actually ends, and tell filesystem, that it can grow
[16:03] <Phosie> It's raspi-config, but isn't that only with the Raspbian image?
[16:05] <Bushmills> a more pedestrian approach could be to change partition table with a tool like gparted, then grow partition with resize2fs
[16:06] <Bushmills> you may want to do that in a different computer
[16:07] <esing> Ye, that's how it is explained in post #8
[16:07] <esing> (since openelac doesn't seem to come with raspi-config)

[17:04] <nerdboy> did you try -X ?
[17:05] <Phosie> I don't think so.

[17:11] <Triffid_Hunter> Phosie: ssh -Y you@otherhost, then echo $DISPLAY. if it gives a blank line, it's not being forwarded. check logs
[17:11] <Grievre> what I find interesting is that tunneling X11 through ssh is actually much faster than doing it the direct way (setting $DISPLAY to ip:port
[17:11] <Triffid_Hunter> Phosie: if it says something like :10.0 or localhost:10.0 you're good to go, start your X apps
[17:12] <Phosie> localhost:10.0

[17:58] <vergil> same results if I compile my own, so I'm just trying to rule out the platform
[17:58] <ShiftPlusOne> ubuntu?
[17:58] <ShiftPlusOne> ah "not on pi", nvrm
[17:58] <Phosie> #ubuntu might be more help
[17:59] <vergil> It's not strictly an ubuntu problem. No issue on other chipsets with the distro
[17:59] <Grievre> I would debug it myself were I in your situation
[17:59] <vergil> I've narrowed it down to my arm board, and was just wondering if any pi folks had a segfault at start as well.

[18:00] <pellis> whats a good way to automate downloads for TV and movies via torrents? i have transmission running but avoiding the manual step of looking through what to download and when is a new episode would be a big win
[18:00] <vergil> Right, before I dug in too deep I wanted to see if it was an arm thing. I've seen talk on pi lists with scummvm seg'ing for no reason
[18:00] <vergil> but it was for an older version
[18:01] <Grievre> do you have a backtrace?

[18:02] <Grievre> why is this not already something to justify fixing it?
[18:02] <vergil> at the point I've put several hours into it, if it works on Pi, it's more worthwhile to say screw it and dump the pandaboard :)
[18:03] <Grievre> oh pandaboard um
[18:03] * Grievre shrugs?
[18:03] <Grievre> why don't we do a backtrace and I'll try to see if I can figure it out? I'm good at these things

[20:58] <Bushmills> that's right, by looking at the schematics one won't mess
[20:59] <IT_Sean> That is correct. YOu can power the Pi via the 5v and GND pins on the GPIO header. THis configuration is not recommended, however.

[21:29] <KuduIO> does SD card performance mattermuch though?
[21:30] <Bushmills> depends

[22:23] <SpeedEvil> job done
[22:23] <pksato> sendmail, exim, postfix, etc...

[22:25] <Bushmills> g2nightmare: install, configure, test
[22:25] <g2nightmare> well i want to send emails from my own domain name or a unique one
[22:25] <g2nightmare> instead of like gmail
[22:25] <g2nightmare> all of the examples i found had gmail :|
[22:27] <Bushmills> there exist interactive smtp server configuration frontends, called "text editors"
[22:27] <g2nightmare> ?
[22:27] <Bushmills> and i'd go along with ozzzy, preferring postfix over sendmail
[22:28] <pksato> and have the zimbra.
[22:28] <g2nightmare> will i need a web server too?
[22:28] <Bushmills> no
[22:29] <ozzzy> just a text editor
[22:29] <Bushmills> what one really needs is air, water, food, shelter, protective clothing, basic hygiene and social interaction
[22:29] <Armand> All you need is love...
[22:29] <Armand> *fnaar*
[22:29] <g2nightmare> i mean if you're just trying to be sarcastic
[22:29] <pksato> g2nightmare: justs install any smtp daemon, and point dns mx to you new server ip.
[22:29] <g2nightmare> i really just want to set up a webserver and be able to send emails from it without having my ip address shown
[22:30] <Bushmills> why do you want to set up a webserver if you don't need one?
[22:31] <g2nightmare> i want to host a personal website
[22:31] <IT_Sean> you want to send mail without your IP being shown? Are you a spammer?
[22:31] <g2nightmare> no i literally just bought my first pi and i want to be able to have family emails and have my resume on a website
[22:31] <g2nightmare> but to my knowledge
[22:31] <g2nightmare> my ip address will be shown
[22:31] <g2nightmare> since i don't have a dns
[22:31] <IT_Sean> do you want to receive mail on the Pi?
[22:32] <Bushmills> do you have a static ip address?
[22:32] <IT_Sean> YOu'll need a static IP, and DNS records, if so.
[22:32] <g2nightmare> my ip is relatively static? i guess it changes month to month i would assume
[22:32] <Bushmills> may not be good enough
[22:32] <g2nightmare> i'm familiar with getting a dyndns account at the very least
[22:33] <Bushmills> many servers refuse mail coming from non-static addresses
[22:33] <Vlad> more to the point, many servers refuse mail coming from residential ranges
[22:33] <Armand> I would say you're better off renting a small hosting package, but then.. I'm biased, I work for a webhosting provider. ;)
[22:33] <Vlad> and your ISP might even block incoming port 25
[22:33] <IT_Sean> ur gonna need a proper static IP.
[22:33] <g2nightmare> and i do that by contacting my host?
[22:34] <pksato> most ISP now block port 25 to reduce spam.
[22:34] <Bushmills> rent a dedicated server, or even a virtual server
[22:34] <IT_Sean> YOu will likely need to upgrade to a business account.
[22:34] <IT_Sean> as opposed to a residential account.
[22:34] <ozzzy> dyndns.org gives good service
[22:35] <pksato> or, rent a low cost VPS.
[22:35] <Bushmills> or put your raspberry at a colocation site
[22:35] <ozzzy> now that would be a neat picture... a shelf at a colo with a pi sitting on it
[22:36] <ozzzy> wonder how much they'd charge you

[22:39] <g2nightmare> maybe this is a bad first project.
[22:39] <IT_Sean> MarquessDeBonBon: don't be ignorant.
[22:39] <MarquessDeBonBon> You get free static IPs with a business line.
[22:42] <g2nightmare> so what do you recommend for handling dynamic dns?
[22:42] <Bushmills> bind + nsupdate
[22:42] <g2nightmare> elaborate? i'm 5 years old in the IT world
[22:43] <Bushmills> or a VPN

[22:46] <g2nightmare> that doesn't really help

[22:47] <Bushmills> nevertheless is that what i recommend
[22:47] <Bushmills> i can hardly make my recommendations depending on your level of understanding, can't I?
[22:47] <g2nightmare> so if i buy a domain name at godaddy
[22:47] <g2nightmare> can i host it at home
[22:48] <Bushmills> you want a static ip address for the nameservers
[22:48] <g2nightmare> i don
[22:48] <g2nightmare> i don't want to buy a business package with comcast.
[22:48] <IT_Sean> you will need to A) register your domain name, AND B) get a static IP
[22:48] <Bushmills> then you can't really host it at home
[22:48] <g2nightmare> if it changes, can't i update the ip address?
[22:49] <g2nightmare> it's not like 1 day of downtime would be huge for me.
[22:49] <IT_Sean> If you want to host it at home, you need the static IP.
[22:49] <g2nightmare> surely it shouldn't be a requirement to have a static ip.
[22:49] <g2nightmare> i can change the settings when it changes, can't i?
[22:49] <IT_Sean> If you want to receive mail to that server, you need the static IP.
[22:50] <IT_Sean> if the IP changes, incoming mail may bounce as non deliverable.
[22:50] <pksato> or, use a now super expensive domain service of gmail.
[22:50] <ozzzy> I ran a mailserver using dyndns' service and their IP updater
[22:50] <Bushmills> if you want to reliably send mail from that server, you'd need a static address as well

[22:50] <ozzzy> it worked
[22:50] <g2nightmare> perfect
[22:51] <g2nightmare> you're speaking my language

[22:51] <g2nightmare> hmm ok
[22:51] <pksato> most dynamic ip are blacklisted on anti-spam services.
[22:51] <g2nightmare> i wonder if comcast does.
[22:51] <g2nightmare> http://customer.comcast.com/help-and-support/internet/list-of-blocked-ports/
[22:51] <g2nightmare> they say to use 465
[22:52] <ozzzy> that's for their mail server
[22:52] <g2nightmare> so i won't be able to do it? even if i do 465?
[22:53] <ozzzy> perhaps
[22:53] <Bushmills> you wanted to run your own mailserver, not use theirs.
[22:53] * dreamon (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[22:53] <pksato> 465 is a client to server connection port, to oulook send email.
[22:53] <Bushmills> how does it help to connect to theirs through tcp/465?
[22:54] <g2nightmare> maybe i should just do the webserver idea.
[22:55] <Alfihar_> it might be easier to look around when you are buying your domain, as some sellers provide free email services
[22:55] <pksato> some isp have a email relay service.
[22:55] <g2nightmare> i already bought a domain and hosting, but i figure this would be a fun project and i can get around that
[22:55] <ozzzy> I'm about to give up on the serial port thing
[22:56] <Alfihar_> yeah I've been thinking of setting up an email server on my RPi though never got round to it, I think my ISP's a bit friendlier for this kind of thing though

[22:58] <ParkerR> Any DNS service
[22:58] <g2nightmare> i would assume to use the dyndns but i have a .com purchased at godaddy i should be able to point their dns to my ip right?
[22:58] <ParkerR> DynDNS, FreeDNS
[22:58] <ozzzy> dyndns.org
[22:58] <g2nightmare> right, so i have to transfer my domain or change it at godaddy?
[22:58] <g2nightmare> or either
[22:58] <ozzzy> as I said... they're free and provide a daemon that automagically adapts to a dynamic dns
[22:58] <ozzzy> you don't need godaddy
[22:58] <pksato> http://www.noip.com/services/managed_mail/inbound_port_25_unblock.html
[22:59] <g2nightmare> yeah but is it a .com or somecrap.morecrap.mysite.com

[23:00] <Bushmills> CNAMEing zone apex violates RFCs
[23:00] <ozzzy> you want it all and you want it free
[23:00] <g2nightmare> well because i already have my website out in the public and on business cards
[23:01] <g2nightmare> it would kind of suck if i had to change my domain name, no?
[23:01] <g2nightmare> and no that's not true.
[23:01] <Bushmills> that's what you can do with using free slave nameservers
[23:01] <g2nightmare> i pay for my hosting and i pay for my domain.
[23:01] <g2nightmare> maybe i just wanted a cheapter alternative.

[23:27] <sandman> Is it true that heat isn't the true killer of hardware; it's overvoltage? That is, if a chip runs hot, it may reduce the lifespan... but voltage is what _really_ lowers the lifespan?
[23:29] <Bushmills> well, so do bulldozers
[23:30] <sandman> That doesn't help me, really =) But thank you for that astute observation.

[23:31] <Bushmills> overvoltage cause multiple factors. whereof additional heat can be one.
[23:33] <Bushmills> there's another potential killer: thermal variation
[23:33] <Schalla> What's the topic?
[23:33] * zhost (~pp@host- Quit (Ping timeout: 256 seconds)
[23:33] <sandman> What's a more sensitive issue for hardware, voltage or heat?
[23:33] <Bushmills> that adds a mechanical stress component to the devices' degradation
[23:34] <Schalla> I guess voltage rather then heat. Because voltage always results also in heat it might be worse then only heat.
[23:35] <Schalla> Also the most chips are fine with 80??C+
[23:35] <sandman> Yeah, that's what I was thinking.
[23:35] <sandman> Thirdly, it seems to me the Turbo mode is the most damaging, as it introduces the thermal variation Bushmills was talking about, increased voltage, and of course increased heat.
[23:35] * sphenxes01 (~sphenxes@91-119-99-218.dynamic.xdsl-line.inode.at) has joined #raspberrypi
[23:36] <Schalla> What is thermal variation? That the temperature changes extremely depending on the last?
[23:36] <sandman> The variation also seems to result in SD card corruption. The reason for this exactly I don't know, since it's not like it's writing corrupted data to the SD card as a result of misprocessed stuff sitting in a buffer or something.
[23:36] <sandman> Seems to be some sort of very sensitive timing issue with the SD card hardware or driver or something
[23:36] <Schalla> Weird.
[23:36] <sandman> Schalla: I think so. Getting very hot, then cool, then hot, then cool
[23:36] <Schalla> Format doesn't help?
[23:37] <sandman> Sure. Re-imaging the SD card fixes it. Then it'll get corrupted again with the Turbo OC, eventually

[23:41] <hot2trot> i ahd to get pulseaudio to actually get the bluetooth to connect inthe first place
[23:41] <Bushmills> Schalla: probably. eagle for example has a 3d renderer, and there exist eagle files of raspberry
[23:41] <sandman> hot2trot: Well, perhaps if you just leave out the -o hdmi
[23:42] <hot2trot> sandman: tried that
[23:42] <Schalla> Bushmills: Thought about a HTMl5 Livemodel, maybe a integration of the status of the GPIO ports e.g.
[23:42] <sandman> Other than that, if it only works through Pulse, I'd figure you'd need to figure out a way to push the audio, likewise, to pulse.
[23:42] <Schalla> + display on the chips of the termperatur
[23:42] <Bushmills> http://www.raspberrypi.org has a forum thread about 3d
[23:42] <sandman> hot2trot: Are you able to get other sound files to play?
[23:42] <Schalla> You remember which area?
[23:42] <pksato> hot2trot: omxplayer only play audio trough SoC. Not extenal audio device, like bluetooth.
[23:42] <Bushmills> 3d models, not 3d graphics output :)
[23:43] <hot2trot> pksato: my tears are swelling up
[23:43] <Schalla> Creating a 3d model with html5 might be also hard.
[23:43] <Schalla> When you wanna turn it with the mouse, e.g.
[23:43] * sphenxes01 (~sphenxes@91-119-99-218.dynamic.xdsl-line.inode.at) Quit (Ping timeout: 248 seconds)
[23:43] <sandman> Well, what's bluetooth's audio device under /dev?
[23:44] <sandman> Or rather, the speaker's audio device.
[23:44] <hot2trot> sandman: dunno
[23:46] <sandman> Here
[23:46] <hot2trot> yes
[23:46] <sandman> pastebin your /dev directory please
[23:47] <sandman> Don't paste it in chat, just a pastebin link to it. Have you used it before?
[23:47] <sandman> pastebin, that is?
[23:47] <hot2trot> i think I can figure it out
[23:47] * Phosie|Away is now known as Phosie
[23:48] * lupinedk is now known as Lupinedk
[23:48] <sandman> Yeah, just send me the link to the list of device nodes. basically, what I'd like to do is figure out what devnode it is, and see what happens if we 'echo "FSD(&^#*($&@(D&F^*(SDHFJKSDHFISD&FYS(DF" >/dev/bluetoothspeakers', basically.
[23:48] <Bushmills> bluetooth audio output solution are frequently pulseaudio based
[23:48] <hot2trot> it is pulseaudio based
[23:48] <Bushmills> supporting programs output to pulse through a lib
[23:48] <hot2trot> i just don't know how to make the raspberry pi use pulseaudio
[23:48] <sandman> If you hear some sort of scratching sound when you do that, then we could just figure out how to output the sound to a file, except redirect it to /dev/bluetoothdevice
[23:49] <sandman> Hrm. I see.
[23:49] * Espen-_- is now known as EspenN
[23:49] * xCP23x (~xCP23x@ has joined #raspberrypi
[23:49] * [SkG] (~sconde@unaffiliated/skg/x-897332) Quit (Quit: Saliendo)
[23:49] <Bushmills> hot2trot: you'd want to tell programs to use pulseaudio for output
[23:50] <hot2trot> Bushmills: how?
[23:50] <Bushmills> sometimes you put that into config files, sometimes you select from a menu
[23:50] <chod> loads of info to read through here hot2trot
[23:50] <chod> http://www.instructables.com/id/Turn-your-Raspberry-Pi-into-a-Portable-Bluetooth-A/#step1
[23:51] <chod> this may be bettter
[23:51] <chod> http://www.instructables.com/id/Bluetooth-Speakers-using-Raspberry-Pi/
[23:51] <sandman> Good call, chod.
[23:51] <sandman> I haven't read those, but instructables are generally good.
[23:51] <hot2trot> chod: this is, unfortunately as most of the search results show, how to make the raspberry pi the bluetooth dongle so to speak
[23:51] <hot2trot> both of those
[23:52] <chod> but it still goes through the audio setup for blue tooth
[23:53] <sandman> There should be a way of somehow creating a devnode for it.
[23:53] <sandman> And if so, then we can just use standard piping.
[23:54] <sandman> I generally shy away from anything which doesn't follow UNIX philosophy, because things become a headache. PulseAudio seems un-UNIX-ish, correct me if I'm wrong.
[23:54] <hot2trot> well, pulseaudio was the only way I could get the bluetooth actually paired with the speakers
[23:55] <Bushmills> t's origin was the enlightenment sound server which also became the gnome audio server
[23:55] * enque (~enque@ip70-160-27-9.hr.hr.cox.net) has joined #raspberrypi
[23:55] <sandman> Bushmills: I think I heard that before, yeah.
[23:56] * zoktar (~zoktar@unaffiliated/zoktar) Quit (Ping timeout: 240 seconds)
[23:56] * discopig (~discopig@unaffiliated/discopig) has joined #raspberrypi
[23:57] <Bushmills> there's some controverse about that point. some call it "replacement" while other say "forked" or at least "inspired"
