[00:07] <Laurenceb> hi
[00:07] <jonsowman> hello
[00:07] <Laurenceb> Randomskk: still interested in your quadcopter?
[00:07] <Randomskk> yes
[00:08] <Randomskk> still working on the motor controllers, at that, sadly :(
[00:08] <Randomskk> lack of time, money and oscilloscope
[00:08] <Laurenceb> heh me too
[00:08] <Laurenceb> need to buy a tectronix DSS as soon as I have some more cash
[00:08] <Randomskk> I've got motors spinning
[00:08] <Randomskk> but not fast enough for takeoff
[00:08] <Laurenceb> nice
[00:09] <Laurenceb> I hear that the ST 3 axis gyro wont be suitable
[00:09] <Randomskk> oh?
[00:09] <Randomskk> D:
[00:09] <Laurenceb> apparently it resonates at just 4.1KHz, and the sugnal processing onboard converts vibration around that freuqency down to around DC
[00:10] <Laurenceb> same for their three axis analogue one
[00:10] <Randomskk> that is unfortunate
[00:10] <Randomskk> and quite annoying
[00:12] <Laurenceb> yes, guess theres still invensense, but the drift is annoying
[00:12] <Laurenceb> at least it has a very good temperature sensor, so you can calibrate out a lot
[00:13] <DanielRichman> raaaaaaaaaaargh it works
[00:13] <Randomskk> what is working now?
[00:13] <DanielRichman> that took way longer than it should have (stage 2)
[00:13] <Randomskk> forking?
[00:13] <DanielRichman> yeah. You're not going to like this
[00:13] <Randomskk> Laurenceb: I guess that's fair enough
[00:13] <Randomskk> DanielRichman: oh?
[00:13] <DanielRichman> I had to copy a start-stop-daemon binary in
[00:13] <DanielRichman> and use the -b "FORCE DAEMONIZE" flag
[00:13] <DanielRichman> that's the only thing I coudl find out that would fork properly. I'll have a look at the sauce and see if I can find out why
[00:16] <Laurenceb> Randomskk: theres always this as well http://ukhas.org.uk/code:7_state_ekf_with_bias
[00:17] <Laurenceb> but eats the cpu somewhat - three more elements in the state vector, and cpu cycles per iteration scales with state vector size ^3
[00:18] <Randomskk> yum
[00:18] <Randomskk> I can't wait to get coding the flight computer tbh
[00:18] <Randomskk> bloody motor controllers
[00:18] <Randomskk> atm I guess I'll be sticking with my 2+1 axis gyros
[00:18] SpeedEvil (~user@tor/regular/SpeedEvil) left irc: Ping timeout: 246 seconds
[00:19] <Laurenceb> its kind of awesome that it calibrated all the gyros using just an accelerometer - I didnt even realise that was possible
[00:22] <Laurenceb> you can see a added a bias of 0.05 radians/second to the yaw in the first plot, and it fixes itself
[00:22] <Randomskk> huh. clever.
[00:23] <Laurenceb> after 80 seconds total yaw error when its placed back on the table is about 2 degrees
[00:24] <Randomskk> that's pretty decent.
[00:24] <Randomskk> though, how much of that 80 seconds is spent getting there?
[00:24] <Laurenceb> if you imagine the IMU is tilted to one side and held steady, then if the yaw gyro is biased the yaw gyro gives you a non zero rate output whilst the accel vector is stationary
[00:25] <Laurenceb> if the gyro was telling the truth the accel vector would be spinning about the z axis
[00:25] <Randomskk> ah, right, yea.
[00:25] <Laurenceb> that how the kalman does the fix
[00:25] <Laurenceb> its pretty smart stuff
[00:26] <Randomskk> oh, that is very neat, I get it
[00:26] <Laurenceb> you can see bias starts to get adjusted around 5 seconds
[00:26] <Laurenceb> as soon as the board is tilted
[00:27] <Randomskk> yea
[00:27] <Laurenceb> but it takes a while to get to a stable value - would be _way_ better with a magno as well
[00:27] <Randomskk> relatively innocent looking code
[00:27] <Randomskk> well totally meaningless to just look at
[00:28] <Laurenceb> of course to be really clever you'd stick the position and velocity into the state vector as well
[00:28] <Laurenceb> then you could stick the gps data in
[00:28] MoALTz (~no@188.147.105.73.nat.umts.dynamic.eranet.pl) left irc: Quit: Leaving
[00:28] <Randomskk> I was considering this
[00:28] <Laurenceb> and itd be used to correct the gyros all other groovyness
[00:29] <Randomskk> literally sticking in the entire state - 3d position, 3d velocity, 3d acceleration, 3d rotation, 3d rate of rotation
[00:29] <Laurenceb> I did a roungh calculation using singles for all the variables youd get about 10 hz on an stm32 doing that
[00:29] <Randomskk> but like, that's a massive state vector
[00:29] <Laurenceb> you can leave out 3d rate of rotation and 3d accel
[00:29] <Randomskk> true, not really needed as state info
[00:29] <Laurenceb> but I was thinking of having gyro bias in there as well
[00:30] <Laurenceb> it can be read directly
[00:30] <Randomskk> well might want 3d accel
[00:30] <Randomskk> it can be read directly from the sensors but don't you want it filtered?
[00:30] <Randomskk> or does it get filtered without having to be in the state vector?
[00:30] <Randomskk> you can read 3d position directly from the gps
[00:30] <Laurenceb> hmm yeah AIUI it doesnt help to put it into the state vector
[00:31] <Laurenceb> to behonest I copied a lot of the basic algorithm from some papers in the journal of navigation
[00:32] <Laurenceb> and they said to leave out the accel and rotation from that state vector so...
[00:32] <Randomskk> fair enough, I imagine they know what they're talking about
[00:33] <jonsowman> Randomskk: has that border changed pulled onto SRCF ok?
[00:33] <Randomskk> yes
[00:33] <jonsowman> thanks
[00:33] <Laurenceb> i simpkified it down to just an attitude filter as working out all the jacobians was giving me a massive brainache
[00:33] <jonsowman> GUI all okay now?
[00:33] <Randomskk> yup
[00:33] <jonsowman> :)
[00:33] <Randomskk> still massively in shock about _rjw
[00:33] <jonsowman> me too
[00:33] <Laurenceb> is he ok?
[00:33] <Randomskk> oh, he's fine
[00:34] <Randomskk> we just found out that his code that's been sitting around since dec 09 actually runs predictions on the web
[00:34] <Randomskk> http://www.srcf.ucam.org/~cuspaceflight/predict_rjw/
[00:34] <Randomskk> we just never saw the "New prediction" button on the top right
[00:34] <Randomskk> for 8 months
[00:34] <Randomskk> until finally finishing jonsowman's and rolling it out
[00:34] <Randomskk> http://www.srcf.ucam.org/~cuspaceflight/predict/
[00:34] <Laurenceb> lol
[00:34] <jonsowman> typical
[00:34] <Laurenceb> ooh sweet graphics
[00:34] <jonsowman> wait 3 months for a predictor
[00:35] <jonsowman> then two come along at once
[00:35] <jonsowman> etc
[00:35] <Randomskk> Laurenceb: I'm close to just buying motor controllers and getting to work on the flight computer
[00:35] <Randomskk> I really want this thing flying
[00:35] <Randomskk> and I really want to do clever maths with it
[00:35] <Randomskk> no one seems to do clever maths on their quads
[00:35] <Laurenceb> Ill try and finish my board layout - I'll email you a copy
[00:35] <Laurenceb> very busy to rest of week tho :(
[00:35] <Randomskk> there are a lot of people implementing basic filters, a few doing some kind of kalman, and some with external position tracking systems doing cool things with the quad
[00:35] <Laurenceb> just need very good check over now
[00:35] <Randomskk> yea, I'm working full time so don't get home until late, haven't been paid from the previous job yet, etc
[00:36] <Laurenceb> I do _not_ want to order a load of boards with pins 28 and 1 mixed up
[00:36] <Laurenceb> etc
[00:36] <Randomskk> I'll be happy to look over it for you, if you want
[00:36] <Laurenceb> oh ST are giving out freee LSM303DLH samples
[00:36] <Laurenceb> thanks

[11:08] <earthshine> morning
[11:08] <m1x10> hi earthshine
[11:08] <m1x10> do u have the fsa03 breakout ?
[11:12] <earthshine> sorry no
[11:13] <m1x10> ok
[11:13] <earthshine> i'm not going to sell the FSA03 any more as sales were pathetically slow - even at the cheap price I was selling it at
[11:13] <m1x10> you sale things?
[11:13] <earthshine> http://www.earthshineelectronics.com/
[11:14] <m1x10> :0
[11:14] <m1x10> :)
[11:14] <juxta|console> earthshine: did you end up hearing back re that module?
[11:15] <earthshine> no i didn't
[11:15] <earthshine> i've re-emailed them several times too
[11:15] <earthshine> i will keep chasing
[11:15] <earthshine> it is bad service
[11:15] <juxta|console> bummer
[11:16] <m1x10> fsphil, do you believe its normal to mail back esawdust.com and complain about the module ?
[11:16] <earthshine> what was wrong with it?
[11:17] <fsphil> m1x10, no harm in trying. it's possible they have experience with this
[11:17] <m1x10> earthshine I got it with its breakout. It worked fine for one week. From yestarday does not lock.
[11:18] <earthshine> you sure it isn't something you did?
[11:18] <m1x10> timbomel has the same issue with the same breakout
[11:18] <earthshine> Have you taken it outside and left it running for about an hour?
[11:18] <jonsowman> morning all
[11:18] <Upu> morning
[11:18] <m1x10> earthshine I was working with it in my balcony for 1 week locking almost immediately
[11:19] <earthshine> If you have taken power off it, even for a short while, it will lose its database so you need to take it outside and let it download the data - after that it shoudl work, as long as you keep it powered up by a backup battery
[11:19] <earthshine> you haven't accidently given it too much power? It is very sensitive to its power needs
[11:20] <m1x10> two days before I started playing with ublox protocol. I also dont use its battery. For one week i was supplying it with 3.3v 50mA
[11:20] <earthshine> was it a regulated supply?
[11:20] <m1x10> nop
[11:21] <earthshine> oh dear
[11:21] <m1x10> its was getting power from 3.3v pin on arduino duemilanove
[11:21] <jonsowman> that is regulated
[11:21] <m1x10> which comes from FTDI chip capped at 50mA
[11:22] <earthshine> ahh then it should be fine
[11:22] <m1x10> yep
[11:22] <earthshine> did you try using uCenter to flash everything back to the default settings ?
[11:22] <m1x10> I just started a couple of minutes ago with ucenter
[11:23] <earthshine> reflash it back to the default settings, then try again
[11:23] <earthshine> but you WILL need to take it outside, let it get lock and LEAVE it outside for a while
[11:23] <earthshine> once it has been runijng outside, with lock, for about 30 mins, the almanac should be refilled and you can bring it back inside
[11:24] <earthshine> if it still doesn't work, then you've broken it
[11:25] <jonsowman> ping DanielRichman
[11:26] <m1x10> earthshine I will try your advice
[11:26] <earthshine> good luck
[11:27] <jonsowman> eam52: adam and I got the predictor running on SRCF
[11:28] <m1x10> default configuration brings it to Eco mode
[11:30] <m1x10> earthshine, why you say Ive broken it?
[11:30] <m1x10> from what action?
[11:32] <earthshine> no idea
[11:32] <earthshine> or it was faulty
[11:32] <earthshine> but if it was working then it is more likely just settings
[11:32] <m1x10> it was working a week. after i played with ublox it died.
[11:32] <earthshine> or maybe you've accidentally shorted one of the tiny contacts or something
[11:33] <earthshine> then it is probably just settings - reflash it
[11:33] <m1x10> i did it
[11:33] <m1x10> now its sitting on the window
[11:33] <m1x10> im waiting
[11:33] <m1x10> i leave in a high altitude 130m so im getting signal easily
[11:34] <m1x10> the gps on my pda locks in a minute
[11:37] <earthshine> do you have it connected to ucenter whilst you wait for lock?

[11:40] <earthshine> do you have the satelittes view page ?
[11:40] <m1x10> you mean the sky view tab ?
[11:41] <m1x10> i have opened the skyview and the text console
[11:41] <earthshine> any satellites showing?
[11:42] <m1x10> im getting the nmea sentences filled with zeros. On the skyview I onlt see the circles
[11:43] <m1x10> no, no satellites.
[12:00] <earthshine> oh dear
[12:00] <earthshine> sounds like it is corrupt
[12:10] <m1x10> still no sats
[12:10] <m1x10> 30min no sats
[12:10] <earthshine> it's dead

[12:48] <earthshine> Is it true you are getting a vinyl cutter?
[12:48] <fsphil> ah you did both -- it really does seem to be faulty
[12:49] <earthshine> wrong channel
[12:49] <m1x10> fsphil can I blame esawdust.com for this?
[12:49] <fsphil> well, at least ask them nicely first :)
[12:49] <fsphil> they may have had this happen to other customers too, if it is a common fault
[12:49] <fsphil> and they might be able to suggest something
[12:51] <juxta|console> fsphil, m1x10: the FSA03 doesnt have any flash memory or eeprom at all - if you unplug the power (and backup battery) from it, it's as reset as it will ever be
[12:51] <m1x10> ok juxta. We fully know that it cannot be damaged by playing with ublox protocol.
[12:51] <earthshine> yep: hence the battery backup is pretty much essential

[16:12] <jonsowman> so does it Just Work?
[16:13] <DanielRichman> jonsowman: I've since upgraded it so that I can put both the ssh host key and my own public key in the initrd so I can perform host verification
[16:13] <DanielRichman> ie. I generated it now and bundled it with the installer
[16:13] <DanielRichman> and no need for a password. It does indeed Just Work
[16:13] <jonsowman> :D :D
[16:15] <DanielRichman> I thought I was going to have to recompile d-i; but fortunatly cpio has an "append" mode so I can just specify a few files to shove onto the end of the initrd
[16:16] <jonsowman> so this entirely makes possible Ubuntu deployment on the ukhas server?
[16:16] <DanielRichman> yup. Does the above youtube video warrant a painting of payloads pink or does it actually have to be done
[16:17] <juxta> has a server been organised already? =o
[16:17] <DanielRichman> ping Upu
[16:17] <jonsowman> I think it has to be done DanielRichman
[16:17] <DanielRichman> juxta: Upu has offered a spare dedicated rack monster in a colo
[16:17] <jonsowman> juxta: Upu has donated a dedi to UKHAS
[16:17] <juxta> awesome!
[16:18] <juxta> three cheers for Upu! :D
[16:18] <jonsowman> but it's running Centos
[16:18] <DanielRichman> there are still arguments for a VPS vs a dedicated monster but I think the way it's going, it looks like we'll be taking up his offer
[16:18] <DanielRichman> it's not official yet though
[16:18] <jonsowman> especially avec alchemy
[16:18] <jonsowman> how long did this take you DanielRichman?
[16:18] <DanielRichman> I still got 8 hours of sleep
[16:18] <juxta> well you could cut the dedi up into a few VPS' ;p
[16:19] <DanielRichman> juxta: no hardware virt
[16:19] <juxta> oh :(
[16:19] <jonsowman> it'd be slow as
[16:19] <juxta> yeah

[16:19] <jonsowman> hehe
[16:19] <DanielRichman> once I'd got past the daemonizing hurdle
[16:20] <jonsowman> seriously well done
[16:20] <DanielRichman> video codec hell is nasty

[16:20] <jonsowman> true
[16:20] <jonsowman> pink payload
[16:20] <jonsowman> juxta: Upu has promised to make this payload pink in the event that this works
[16:20] <juxta> haha
[16:21] <DanielRichman> The other advantage is that the human does the partitioning and can therefore deal with the RAID stuff; I've never done a raid install before
[16:21] <juxta> just looking now - you're converting the centos server to ubuntu with no physical access? =\
[16:21] <DanielRichman> that's what I'm doing in that video juxta, yes
[16:21] <juxta> awesome work
[16:22] <juxta> where is the colo by the way?
[16:22] <DanielRichman> I've got the VM console open so that you can see what's happening, but after the centos install I didn't lay one click or keystroke on it
[16:23] <jonsowman> manchester?
[16:23] <DanielRichman> yes, I think so
[16:27] <juxta> did 'captain planet' ever air in the UK?

[18:18] <m1x10> I just sew some activity to fsa03
[18:18] <m1x10> As you said from the mail The problem is the antenna
[18:18] <esawdust> hi kostas
[18:18] <m1x10> i turned a bit
[18:18] <m1x10> and now its starts receiving
[18:18] <esawdust> interesting
[18:18] <m1x10> too fragile?
[18:18] <esawdust> the sarantel can be both a boon and bane
[18:19] <griffonbot> @nearsys: Look for updates to teh BalloonSat Mini, Easy, Extreme, and of course the new UltraLight. Test PCBs to be here after next week. #ARHAB [http://twitter.com/nearsys/status/20319760837]
[18:19] <m1x10> i still havent got a lock
[18:19] <m1x10> but I see lots of activity in uCenter
[18:19] <esawdust> If you look closely, there's not a lot of mechanical reinforcement in the connection of the Sarantel to the pcb of the fsa03
[18:20] <esawdust> the helicals are also not as sensitive I've found than just a pure flat ceramic, but I don't have any numbers to back it up, just what I've observed
[18:20] <m1x10> im sure it will lock in some time
[18:20] <esawdust> once they lock, they seem to be fine, but sometimes getting a lock is not always easy
[18:20] <m1x10> at my place I get lock easily
[18:21] <m1x10> but at least now I know the problem
[18:21] <m1x10> the antenna was the last thing to believe
[18:21] <m1x10> and of course its falcom's stupid mechanical assembly
[18:22] <m1x10> if that gps falls 1-2 times then the antenna gets away
[18:22] <esawdust> yes, I would definitely recommend epoxy on the white base - I suppose I could just do that as a matter of assembly on my end
[18:23] <m1x10> esawdust, what is the epoxy?
[18:23] <m1x10> in greek means season :)
[18:23] <esawdust> wow, that's funny - check out: http://en.wikipedia.org/wiki/Epoxy
[18:24] <esawdust> I use this to reinforce the the white sarantel base to both the FSA03 PCB as well as the carrier / breakout board for the module itself.
[18:25] <esawdust> epoxy is just a two-part glue that can harden in 3-5 minutes
[18:25] <m1x10> aaaaaaaaaa
[18:25] <m1x10> look
[18:26] <m1x10> I turn around the antenna
[18:26] <m1x10> not the white neck
[18:26] <m1x10> the cylinder
[18:26] <m1x10> the black thing
[18:26] <m1x10> thats turns
[18:26] <m1x10> that can be turn around itself
[18:26] <esawdust> the black cylinder is just a cap around the helical structure
[18:26] <m1x10> yes
[18:27] <m1x10> i turn the helical antenna
[18:27] <m1x10> around itseld
[18:27] <m1x10> and some soldering pins move on falcom's pcb
[18:27] <m1x10> while i turn
[18:28] <esawdust> this is why the epoxy would be beneficial

[18:42] <jonsowman> hows things?
[18:42] <jcoxon> not bad thanks and yourself?
[18:42] <jonsowman> yes fine thanks :)
[18:42] <jcoxon> just reading about everyone's fsa03 issues
[18:42] <jonsowman> out of interest, what would your vote be for the UKHAS server OS?
[18:42] <jcoxon> its always worked really well for me
[18:43] <jcoxon> jonsowman, oh i don't mind really
[18:43] <jcoxon> not really my department :-p
[18:43] <fsphil> he means centos... *ahem* ;-)
[18:44] <jonsowman> hehe
[18:44] <jcoxon> how about smalllinux2
[18:44] <jonsowman> is your vote centos fsphil?
[18:46] <fsphil> I do prefer centos, but I doubt anything I'd be doing would really be affected by the distro
[18:47] <fsphil> they're all pretty good these days
[18:47] <rharrison> centos here
[18:47] <rharrison> To save Upu a drive
[18:48] <rharrison> hey jcoxon still in Brighton then jcoxon
[18:49] <jcoxon> i'm in brighton right now
[18:49] <rharrison> Like I said
[18:49] <m1x10> jcoxon: I solved my fsa03 issue.
[18:49] <jcoxon> rharrison, latitude?

[18:51] <rharrison> Yep stop right there :-)(
[18:51] <jcoxon> m1x10, hehe i built smalllinux2 - worked great on my 386 with 8mb ram

[19:52] <Randomskk> yup
[19:52] <Randomskk> jonsowman: sparkfun package arrived

[19:52] <Randomskk> but anyway
[19:53] <Randomskk> two more magjacks, two more of the light sensos, two more pressure sensors, five of the toggle switches and three resets
[19:54] <jonsowman> \o/
[19:59] <jonsowman> sounds good
[19:59] <jonsowman> :)
[20:04] <Randomskk> it turns out, mosquitos serve no essential role in the global ecosystem, and nothing would miss them if they suddenly were totally wiped out
[20:07] <jonsowman> erm
[20:07] <jonsowman> excellent
[20:08] <Randomskk> that was your fun mosquito fact for the day
[20:08] <jonsowman> oh right

[20:20] <jonsowman> hello
[20:25] <Wild-Wing> how are ya
[20:26] <jonsowman> im alright thanks, yourself?
[20:40] <m1x10> I did the potential divider circuit and works !! gps up and running. no converts and stupid stuff :)
[20:41] <m1x10> locked in less than 30secs
[20:41] <m1x10> maybe that regulator helps it with ampere
[20:45] <Wild-Wing> im doing good jonsowman
[20:53] <m1x10> vertical velocity
[20:53] <m1x10> curious
[20:54] <m1x10> ublox can tell u that too
[21:04] <fsphil> I think I'm going to put some kind of bubble wrap around the fsa03 -- a shock absorber
[21:04] <jonsowman> wise
[21:05] <m1x10> :)
[21:07] <m1x10> ublox can also tell you if you're ascending/descending !
[21:07] <jonsowman> yes i've always thought that vertical velocity was a silly omission from the NMEA protocol spec
[21:08] <Randomskk> the clue is in the N
[21:08] <Randomskk> boats don't tend to have significant vertical velocity
[21:08] <Randomskk> or altitude for that matter
[21:08] <Randomskk> in fact they tend to spend a lot of time at sea level
[21:08] <m1x10> jonsowman vertical vel comes from ublox protocol, not nmea.
[21:09] <m1x10> ublox got magical stuff
[21:10] <jonsowman> yea i know
[21:41] <Upu> Evening
[21:41] <Upu> Jon was it you doing the fancy remote reload thing on the box ?

[21:42] <Randomskk> he has it working: http://www.youtube.com/watch?v=FShBPtUc76U
[21:42] <Randomskk> on a centos vm, at any rate
[21:42] <Upu> Yeah saw it was very impressed
[21:43] <Upu> so impressed I'm going to see if I can get access to data center on Sat, if he wants to try it on Friday say and it doesn't work I'll go out and do it the old fashioned way
[21:44] <Upu> already located my supplier for bright pink gaffer tape : http://www.gaffatape.com/Fluorescent-Gaffer-Cloth-Tape-1/default.aspx :)
[21:45] <Randomskk> haha excellent
[21:45] <Randomskk> I am looking forward to the pink payload
[21:45] <Upu> you're not going to miss it :)

[22:11] <SiOB> just like to thank the team at the Cambridge University Spaceflight Landing Predictor for an excelent job. We launched a ballon in march 2010 and it was only 3km out..well done
[22:12] <Randomskk> :D
[22:13] <natrium42> where did you launch from?
[22:16] <jonsowman> SiOB: excellent! good work - any details on the launch?
[22:18] <SiOB> http://www.swmarshall66.freeuk.com/balloon/
[22:20] <Randomskk> did keith read his license terms? >_>
[22:21] <jonsowman> er... yea
[22:21] <Randomskk> oooh. some nice photos
[22:22] <SiOB> We've since been educated about the rules.....
[22:22] <Randomskk> http://www.flickr.com/photos/siob2010/4427535861/in/set-72157623488390777/ is nice
[22:22] <SiOB> Ooops
[22:22] <Randomskk> SiOB: hehe
[22:22] <Randomskk> blimey
[22:22] <jonsowman> very nice pics
[22:22] <Randomskk> that transmitter had 10W?!
[22:22] <jonsowman> bet people could hear that from a long way away
[22:23] <SiOB> no... we only output 1 watt
[22:23] <Wild-Wing> thats a good amount of power
[22:23] <Randomskk> ah, okay
[22:23] <jonsowman> 10mW tbh
[22:23] <Randomskk> :P
[22:23] <Randomskk> SiOB: nevertheless good job, have you seen ukhas.org?
[22:24] <jonsowman> .uk
[22:24] <Randomskk> http://ukhas.org.uk/
[22:24] <Randomskk> silly url
[22:24] <jonsowman> habhub.org :D
[22:24] <SiOB> No... but will take a look
[22:24] <Randomskk> we should really register that
[22:24] <Upu> was that a UK launch ?
[22:24] <SiOB> Yeah...uk
[22:24] <jonsowman> seems so
[22:24] <jonsowman> there's not many launches that go on without UKHAS knowing
[22:25] <Upu> very nice pictures
[22:25] <Upu> transmitter seems a little powerful :) Who cares about the law anyway :)
[22:25] <Randomskk> stupid law really
[22:25] <jonsowman> oh it is
[22:25] <Randomskk> we should be allowed to operate /aa
[22:26] <Randomskk> or is it /am or whatever
[22:26] <SiOB> never told anyone we was doing it... just saw a program on tv and thought i could do that.... took a couple of weeks to put together
[22:26] <Randomskk> airborne at any rate
[22:26] <Randomskk> SiOB: solid job, though all the fun is clearly in making your own flight computer :P
[22:26] <Randomskk> the guy you saw on the big bang theory ep hangs around here too.
[22:27] <jonsowman> oh?
[22:27] <SiOB> Tell him thanks for the idea....
[22:27] <Randomskk> wait
[22:27] <Randomskk> I mean bang goes the theory, not big bang theory
[22:27] <Randomskk> subtle but significant difference
[22:28] <Randomskk> sorry for getting your hopes up jonsowman
[22:28] <Randomskk> :P
[22:28] <jonsowman> ah damn
[22:28] <SiOB> how many legal launch places are there in uk....
[22:28] <jonsowman> hehe
[22:28] <jonsowman> who is the chap from BGTT?
[22:29] <Randomskk> SiOB: did you get a NOTAM/launch permission at all?
[22:29] <Randomskk> anywhere can become a legal launch place, you just contact the caa to get a notam
[22:29] <Randomskk> jonsowman: uhm.
[22:29] <SiOB> whats that !!!! .... like i said we've since been educated about the rules
[22:29] <m1x10> allright guys...going to sleep. cu all.
[22:30] <Randomskk> seeya
[22:30] <SiOB> bye
[22:30] <Upu> lol :)
[22:30] <m1x10> haha

[22:30] <SiOB> Ooops
[22:30] <jonsowman> ouch
[22:30] <jonsowman> oh well, too late now
[22:30] <Upu> like close to the international airport ?
[22:30] <Randomskk> do you have planes up north? :P
[22:31] <jonsowman> oh well you know for next time
[22:31] <SiOB> I.... we do
[22:31] <Upu> ah it's cool you were only 12 miles from the airport :o)
[22:31] <Randomskk> eh, it all worked anyway
[22:31] <Upu> wonder if they noticed it
[22:32] <Upu> stealth balloon
[22:32] <jonsowman> i'm guessing it didn't have a radar reflector on it?
[22:32] <SiOB> well they must be quite low then.... not long b4 balloons above
[22:32] <Randomskk> yea, balloons clear the airspace pretty quick
[22:32] <SiOB> get one for next time
[22:32] <jonsowman> radar reflectors aren't required in the UK
[22:33] <jonsowman> they are in the US though IIRC
[22:33] <Upu> would you get a NOTAM to launch that close to the airport ?
[22:33] <Upu> you look like you're on the approach path as well :)
[22:33] <SiOB> ive since been told NO

[22:34] <Upu> Rob is trying to get permission to launch from near York
[22:34] <SiOB> learnt quite alot of the rules since first launch
[22:34] <Randomskk> jonsowman: shoved predictor link on cuspaceflight page
[22:34] <Randomskk> it turns out this is actually made with php
[22:34] <Randomskk> and like, totally pointless php
[22:34] <Upu> which isn't too far from you / me
[22:34] <Randomskk> this dates to henry hallam
[22:35] <jonsowman> Randomskk: thank you
[22:35] <jonsowman> meant to do that earlier and forgot
[22:35] <Randomskk> but like
[22:35] <Randomskk> it's a php file for the menu
[22:35] <Randomskk> that has an array of names to links
[22:35] <jonsowman> er
[22:35] <SiOB> just been updated .... have u seen it
[22:35] <jonsowman> what?
[22:35] <Randomskk> and like
[22:35] <Randomskk> it's called a Dynamical Menu
[22:35] <jonsowman> that's not a word
[22:35] <Randomskk> says you
[22:35] <jonsowman> haha
[22:35] <SiOB> http://www.srcf.ucam.org/~cuspaceflight/predict/index.php
[22:35] <Randomskk> its comments say otherwise
[22:36] <Randomskk> jonsowman: anyway check out cuspaceflight/public_html/include-menu.php
[22:37] <jonsowman> why obfuscate email addresses in a php file?
[22:37] <Randomskk> s/obfuscate/put
[22:37] <jonsowman> point
[22:37] <SiOB> How do you go about getting permission, who do you call or write too
[22:37] <jonsowman> in any case
[22:37] <jonsowman> weird menu
[22:37] <Randomskk> so are we still sponsored by microsoft research?
[22:37] <jonsowman> SiOB: you need to contact the airspace utilisation section at the CAA
[22:37] <jonsowman> AUS
[22:38] <jonsowman> chap there caleld David Miller is the guy you're after
[22:38] <SiOB> right
[22:38] <jonsowman> he deals with all this kind of thing

[22:39] <Randomskk> http://www.srcf.ucam.org/~cuspaceflight/blog/ is on my list
[22:39] <Randomskk> needs theme, static pages
[22:40] <Randomskk> we don't need more than that tbh
[22:40] <jonsowman> true
[22:40] <jonsowman> er.. I think we broke something on the predictor
[22:40] <Randomskk> awww
[22:40] <SiOB> lol
[22:40] <Randomskk> what something
[22:41] <jonsowman> hit Run Prediction
[22:41] <Randomskk> not doing anything here either
[22:41] <Randomskk> but it worked, like, minutes ago
[22:41] <jonsowman> i know

[22:45] <jonsowman> SiOB: I dont think it's a loading issue
[22:45] <Randomskk> not really. it was kind of doing this earlier or something
[22:45] <Randomskk> hang on let me debug it

[22:46] <jonsowman> yea
[22:47] <Randomskk> here be dragons; I stumbled blindly into public_html/source\ code/landing\ prediction/landing_prediction.cpp
[22:48] <Randomskk> I don't really know what your php is doing
[22:48] <Randomskk> I haven't really looked at the php
[22:48] <Randomskk> I mean, I'm sure it's lovely php and all
[22:49] <Randomskk> but I have no idea where that's coming from
[22:49] <Randomskk> oh, hey, a line reference
[22:49] <Randomskk> my guess is the folder wasn't made
[22:49] <Randomskk> and indeed it wasn't
[22:49] <jonsowman> you are correct
[22:49] <jonsowman> but why
[22:49] <Randomskk> so like, shell_exec
[22:49] <Randomskk> you don't get its return
[22:50] <Randomskk> in makePredDir
[22:50] <jonsowman> yea
[22:50] <Randomskk> so presumably that is erroring
[22:50] <Randomskk> does it just return a string? I dunno
[22:50] <Randomskk> but, like, print it
[22:50] <jonsowman> $var = shell_exec("command");
[22:50] <jonsowman> $var would have whatever the shell returns

[22:51] <Randomskk> nothing
[22:51] <natrium42> :P
[22:51] <Randomskk> $var is empty
[22:52] <jonsowman> thats because mkdir doesn't return anything
[22:52] <jonsowman> if it works
[22:52] <jonsowman> did it work>
[22:52] <Randomskk> it should on an error
[22:52] <Randomskk> but it didn't work
[22:52] <Randomskk> well maybe

[22:55] <DanielRichman> Upu: can you quickly remind me what the raid setup is?
[22:55] <Randomskk> but also, it's not making the directory
[22:55] <DanielRichman> Randomskk: yes
[22:55] <Upu> Yeah it's 4 x 750Gb SATA drives on an Adaptec 2800SA I think let me just check the card
[22:55] <Upu> in RAID10
[22:55] <Randomskk> DanielRichman: fair enough. I realise you're probably already excellent at administrating shit but I do have a general checklist of stuff to do on a new ubuntu server if you want
[22:56] <Randomskk> or I could do it, whichever. hang on.
[22:56] <DanielRichman> Randomskk: if you hilight me between now and tomorrow, I will read it when I wake up
[22:56] <DanielRichman> when you say you "have a list", is it already typed?
[22:57] <Upu> Adaptec Model: 2810SA RAID10
[22:57] <DanielRichman> all right Upu and have you ever installed a Debian or Ubuntu system onto a similar raid setup?
[22:57] <Upu> yes it was Debian before I reloaded it

[22:57] <DanielRichman> Upu: did it Just Work (tm) ?
[22:57] <Upu> Yep
[22:57] <Upu> worked off a net install CD
[22:58] <Randomskk> obviously that has 'adam' in it
[22:58] <Randomskk> where you probably don't want adam, like AllowUsers would be better suited to AllowGroups and ssh-users or something
[22:58] <Randomskk> etckeeper comes highly recommended
[22:58] <Randomskk> as the first thing you do
[22:58] <DanielRichman> excellent Upu does it just add a raid item to one of the menus when you ran the installer?
[22:59] <Upu> just sees it as a single drive
[22:59] <DanielRichman> all right Randomskk; yeah there are one or two things in here that I wouldn't have otherwise done but most of it I agree with you; will do
[22:59] <DanielRichman> Randomskk: "iptables"?
[22:59] <Upu> like /dev/cciss/something
[22:59] <Randomskk> http://library.linode.com/email/exim/send-only-mta-ubuntu-10.04-lucid is exim setup as a lightweight, send-only server
[22:59] <DanielRichman> aaaaah so the card is already configured?
[22:59] <Upu> oh yes all set up bootable as RAID10
[22:59] <DanielRichman> oh perfect
[22:59] <DanielRichman> thank you very much again Upu
[23:00] <Randomskk> http://pastie.org/private/1fxro6wxewechretyj4nua iptables sample config, adapt as needed really
[23:00] <DanielRichman> Randomskk: not a postfix fan then?
[23:00] <Randomskk> paladin ~: cat /etc/network/if-pre-up.d/iptables
[23:00] <Randomskk> #!/bin/sh
[23:00] <Randomskk> /sbin/iptables-restore < /etc/iptables.rules
[23:00] <Randomskk> DanielRichman: I love postfix if I was having an actual mail server
[23:00] <Randomskk> but ubuntu has an exim4 package designed for just sending that uses minimal resources
[23:01] <Randomskk> I would argue we do not want to be receiving mail on the server
[23:01] <Randomskk> but a lot of things will require having the ability to send
[23:01] <Upu> just sees the disk array as SDA
[23:02] jasonb (~jasonb@dsl092-009-225.sfo1.dsl.speakeasy.net) left irc: Ping timeout: 240 seconds
[23:02] <DanielRichman> OK. Finally, Randomskk, have you set any of those private pasties to expire?
[23:02] <Upu> on which there are currently 2 partitions 100Mb /boot and the rest is LVM
[23:02] <Randomskk> no, but I don't know if pasties do or not. I'd copy it to a local text file though
[23:02] <DanielRichman> will do. And Randomskk you wanted LVM on the box?
[23:03] <Upu> LVM is a good idea as you can shuffle space round later
[23:03] <DanielRichman> indeed
[23:03] <Upu> oh when you get it working put SNMP and I'll add it to our network monitoring box in Leeds
[23:03] <Randomskk> LVM is great
[23:03] <Randomskk> also, that list is kind of ordered
[23:03] <Upu> I'll give you IPs etc later for the firewall
[23:03] <Randomskk> not very strongly though
[23:04] <Randomskk> :o there's a separate firewall too?
[23:04] <Upu> can have if you want
[23:04] <Randomskk> jonsowman: http://php.net/mkdir
[23:04] <Upu> I have piles of Fortigate 50As lying about
[23:04] <Randomskk> tbh, allow shell_exec
[23:04] <Upu> but currently just using iptables
[23:05] <Randomskk> just iptables seems easiest
[23:05] jasonb (~jasonb@dsl092-009-225.sfo1.dsl.speakeasy.net) joined #highaltitude.
[23:05] <Upu> anyway I'll have a chat with the datacenter guys and see if I can arrange access on Sat
[23:05] <Upu> if needed
[23:05] <Randomskk> jonsowman: also check out mkdir() in php's default mode: 777
[23:05] <Upu> ok night all o7
[23:06] <Randomskk> night
[23:06] <DanielRichman> night
[23:06] Upu (~Upu@ubn.upuaut.net) left irc:
[23:06] <DanielRichman> # Drop all private IP traffic not from allowed hosts
[23:06] <DanielRichman> ^^ will that be necessary?
[23:06] <Randomskk> the whole private IP section isn't really relevent
[23:06] <Randomskk> don't think this has any
[23:06] <sbasuita> uptimed looks jokes :)
[23:06] <Randomskk> gotta have uptimed
[23:06] <Randomskk> https://randomskk.net/ranger/uptime/
[23:06] <sbasuita> just installed it on my desktop (Y)
[23:07] <sbasuita> oh btw you forgot ntpd

[23:07] <sbasuita> sync to http://www.pool.ntp.org/zone/uk
[23:07] <Randomskk> eh. there's ntpd or there's ntpdate on cron
[23:07] <Randomskk> we don't really need to actually run a timeserver
[23:08] <sbasuita> right but you want to install the ntp package
[23:08] <sbasuita> you run the server but it only listens on localhost
[23:08] <sbasuita> ntpdate is pretty nasty ;P
[23:08] <DanielRichman> ntpd does funky stuff like measuring drift etc.?
[23:08] <DanielRichman> anyway whatever; I'm going to sleep
[23:08] <SiOB> Night Guys, thanks
[23:08] <DanielRichman> see you tomorrow
[23:08] <sbasuita> ntpd changes the speed of your clock to keep the time right
[23:08] <Randomskk> seeya
[23:08] <Randomskk> good work btw
[23:08] <jonsowman> see you DanielRichman
[23:09] <jonsowman> looking forward to tomorrow
[23:09] <jonsowman> haha
[23:09] <Randomskk> jonsowman: did you see ^ wrt mkdir() being a function in php
[23:09] SiOB (SiOB@cpc7-stkp7-2-0-cust544.know.cable.virginmedia.com) left #highaltitude.
[23:09] <jonsowman> just looking at it at the moment
[23:10] <DanielRichman> oh almost forgot; if you want to email me your ssh key and preferred username then I can set them up as soon as it's installed
[23:10] <Randomskk> to which address?
[23:10] <DanielRichman> main@danielrichman.co.uk
[23:10] <jonsowman> thanks DanielRichman
[23:10] <Randomskk> cheers
[23:10] <DanielRichman> night 4 real :)
[23:16] <jonsowman> Randomskk: oh....
[23:16] <jonsowman> dear...

[23:17] <Randomskk> ah
[23:17] <Randomskk> well
[23:17] <Randomskk> that explains that
[23:19] <jonsowman> so i changed on my server and pushed to github
[23:19] <jonsowman> now pulling on srcf does nothing to that particular file
[23:20] <Randomskk> well yes
[23:20] <Randomskk> Disk quotas for group cuspaceflight (gid 4535):

[23:20] <Randomskk> cuspaceflight are all out of quota on pip
[23:20] <jonsowman> i'll email SRCF
[23:21] <Randomskk> we are using 1.8gb, jokes
[23:21] <Randomskk> 600MB in svn, 850MB in public_html
[23:23] <Randomskk> in which, 321MB images, 138mb images/Nova10b, 114m gatchan.mp4, 106m archive, 100m radio.zip, etc
[23:24] <jonsowman> emailed sysadmins
[23:28] <jonsowman> is there any way to checkout just that file
[23:29] natrium42 (~natrium@CPE000625d867e2-CM0014045885be.cpe.net.cable.rogers.com) left irc: Quit: Leaving
[23:31] <Randomskk> yea
[23:31] <Randomskk> but you can't checkout just that file from remote server
[23:31] <Randomskk> you need to fetch from yours
[23:31] <Randomskk> which will probably exceed the quota
[23:31] <Randomskk> delete some shit
[23:31] <Randomskk> Radio.zip in public_html isn't needed, will free 100mb
[23:32] <jonsowman> gone
[23:32] <jonsowman> so git fetch origin master
[23:32] <jonsowman> ah ok done it
[23:33] <jonsowman> thanks :)
[23:34] <Randomskk> and then you'd need to merge etc
