[00:40] Action: fsphil is hacking
[00:43] <Wild-Wing> what on gods green earth are you hacking fsphil
[00:44] <fsphil> trying to figure out how to post binary data with libcurl
[00:44] <Wild-Wing> huh in php?
[00:44] <fsphil> c++ ... which I'm also trying to figure out ;-)

[01:20] <fsphil> I've tended to avoid it, sticking to plain C
[01:20] <fsphil> I don't mind it - just find it very odd
[01:26] <Wild-Wing> hehe
[01:26] <Wild-Wing> is c like c++?
[01:29] <fsphil> they share a lot of the syntax, c code tends to be fine in a c++ program
[01:35] <Wild-Wing> ah thats good
[01:50] <Wild-Wing> i wonder how many cameras someone has send up in one payload
[01:53] fergusnoble (~fergusnob@c-67-160-245-238.hsd1.ca.comcast.net) left irc: Quit: fergusnoble
[01:54] <fsphil> the most I've read about is two or three
[01:55] <fsphil> there's little need for many, the payload tends to spin and one camera will face all directions at some point
[01:56] <Wild-Wing> ah
[01:57] <Wild-Wing> how do you stop the payload from spining?
[01:59] <fsphil> not easily :)
[02:00] <Wild-Wing> whats one way you know of
[02:01] <fsphil> Gyroscope could do it, but it would be heavy
[02:02] <fsphil> a small fan / propeller might do too
[02:02] <fsphil> like in a helicopter
[02:03] <Wild-Wing> ah ok thats coool
[02:03] <fsphil> it would be, but nobody's done it so far
[02:03] <fsphil> the spinning isn't really an issue unless you're after video
[02:03] <Wild-Wing> ah
[02:04] <fsphil> I've watched a few hab videos on youtube, they'd make you dizzy pretty quick :)
[02:04] <Wild-Wing> yea would a co2 burst do the same thing?
[02:05] <fsphil> don't see why not, though the supply would be limited
[02:06] <Wild-Wing> well i happen to own some 20oz co2 bottles for paint ball
[02:08] <fsphil> would they last in a 2 hour flight though?
[02:08] <fsphil> i don't know how much would be needed
[02:09] <Wild-Wing> well it contains a pressure of 1200 psi and i could use one for a few hours durring paintball
[02:12] <fsphil> I wonder how that would work with the lower pressure at altitude
[02:12] <Wild-Wing> hmmm well you can reduce it down to something like 20 psi

[02:18] <juxta> CUSF did some experiments with a spin stabilized payload
[02:20] <juxta> http://vimeo.com/3803248
[02:22] <Wild-Wing> huh whats under the payload
[02:25] <juxta> that was to stop it from spinning I'm pretty sure
[02:25] <Wild-Wing> it looked like fabric
[02:35] <Wild-Wing> i wonder how it worked

[02:58] <Wild-Wing> a bouncer host?

[03:30] <Wild-Wing> juxta arent you in the usa?
[03:30] <juxta> no, Australia
[03:31] <juxta> I just got pricing information from a Chinese balloon supplier, seems quite reasonable, now I just have to see what can be done with regards to shipping
[03:31] <Wild-Wing> thats cool
[03:32] <juxta> I suspect they'll want me to order 1000 balloons or so
[03:35] <Wild-Wing> haha well if you get a good price why not
[03:36] <juxta> that'd be $50,000 - $100,000 USD
[03:36] <Wild-Wing> oh ok i didnt know the price

[07:03] <juxta> hi jonsowman
[07:04] <jonsowman> hello juxta :) how's things?
[07:04] <juxta> good good
[07:05] <juxta> getting ready to launch tomorrow :)
[07:05] <jonsowman> getting ready to launch saturday :)
[07:05] <jonsowman> what's the payload?
[07:05] <juxta> nothing fancy, just telemetry again
[07:05] <jonsowman> :)
[07:05] <jonsowman> cool
[07:06] <juxta> have also been chasing up balloon pricing with chinese and indian suppliers
[07:06] <jonsowman> oh nice
[07:06] <jonsowman> did you get anywhere?
[07:06] <juxta> price is quite good, am trying to organise an order & will see how they perform
[07:06] <jonsowman> sounds like good progress
[07:06] <juxta> the largest balloons they make are 2000g, which are around $75USD
[07:06] <juxta> 1000g are around $20
[07:07] <jonsowman> cheap
[07:07] <jonsowman> :o
[07:07] <juxta> very!
[07:07] <juxta> the only issue is going to be coordinating it all

[07:09] <jonsowman> i'm sure it's doable somewhere
[07:09] <jonsowman> *somehow, even
[07:09] <jonsowman> and for $20ea
[07:10] <juxta> indeed
[07:10] <juxta> time to go rig up the carputer

[13:37] <juxta> ping DanielRichman
[13:37] <juxta> or perhaps ping fsphil
[13:38] <fsphil> pong!
[13:39] <juxta> hey there
[13:40] <juxta> I've been doing a bit of testing of the new dl-fldigi and have found something that doesn't work so well in the new version - not sure if it's perhaps an fldigi issue, about to try the vanilla version
[13:41] <jonsowman_work> juxta: which version?
[13:42] <jonsowman_work> what is the issue?
[13:42] <juxta> jonsowman_work: 3.20.1 - I know there were a couple of bugs fixed yesterday but I couldnt find any new win32 binaries
[13:42] <jonsowman_work> hmm ok
[13:43] <jonsowman_work> whats not working?
[13:43] <juxta> it may be to do with the changes to the RTTY decoder in vanilla fldigi - the receive filter bandwidth has dropped down much much smaller, it used to be adjustable in the RTTY options to well above 600hz, default was 575hz
[13:43] <jonsowman_work> hmm interesting
[13:43] <juxta> now the default it 75hz and maximum is 200 - auto frequency correction doesnt work well without the increased bandwidth
[13:44] <juxta> at 75hz it loses the signal even after a very small deviation
[13:44] <juxta> tested it with the old version just now, which is tolerant of me tuning the radio all over the place, new version not so keen on that
[13:45] <juxta> just about to try the vanilla fldigi though
[13:45] <jonsowman_work> ok
[13:46] <fsphil> the filter should still be adjustable
[13:47] <fsphil> aah, only up to 200
[13:47] <juxta> same in vanilla
[13:54] <fsphil> right, the max is 200 even though the filter is automatically set higher than that for certain baud rates
[13:54] <fsphil> I've increased it in my copy to 1000
[13:54] <fsphil> unfornatually I can't build a working windows exe for you
[13:54] <juxta> no worries fsphil
[13:54] <juxta> I'll use DanielRichman's scripts and do so at some stage
[13:55] <juxta> looks like an fldigi bug then?
[13:56] <fsphil> seems to be, I must check when it was changed
[13:58] <fsphil> it's a small change, I've pushed it to my branch on github.
[13:59] <juxta> great :)
[13:59] <juxta> does that merge into jcoxon's master, or does he need to do that?
[14:02] <fsphil> he'll need to do that
[14:02] <juxta> alright
[14:03] <juxta> i think jonsowman_work is hoping to use the new version on saturday, working AFC would be a good thing to have I think
[14:03] <jonsowman_work> indeed
[14:03] <jonsowman_work> would be very handy :)
[14:10] <fsphil> i never noticed any problems with the afc
[14:10] <fsphil> ooh lightning!
[14:11] <juxta> fsphil: the older version didn't seem to be affected
[14:11] <juxta> and likely it wouldnt affect the payloads as they tend to drift slowly, I just figured it was sub-optimal :)
[14:16] <fsphil> yea it was definitely wrong
[14:20] <juxta> it probably would affect you if you're using CAT though
[14:20] <juxta> as the AFC wouldn't follow any tuning changes you made
[14:30] <g8tmv> can fldigi with cat auto adjust the rig to compensate for thermal drift?
[14:41] <juxta> g8tmv: i don't believe it can do it automatically
[14:41] <SpeedEvil> Depends how well the cat is trained.
[14:41] <SpeedEvil> (sorry)
[14:41] <jonsowman_work> heh
[14:41] <juxta> haha
[14:41] <SpeedEvil> The visual amused :)
[14:42] <fsphil> meow
[14:42] <SpeedEvil> If I had any energy, I'd photoshop a cat staring intently at a laptop running fldigi.
[14:42] <fsphil> one paw on the fine tuner
[14:42] <juxta> jonsowman_work: tomorrow my payload is almost certain to outrun me or land in a big area with very few roads
[14:44] <jonsowman_work> :(
[14:44] <jonsowman_work> you never know, might be lucky!
[14:44] <juxta> predictions tell me no ;p
[14:44] <jonsowman_work> don't launch then? save it for a day when you'll get it back :)
[14:44] <juxta> oh we'll get it back
[14:45] <juxta> (probably)
[14:45] <juxta> hehe
[14:45] <jonsowman_work> oh
[14:45] <jonsowman_work> :D
[14:45] <jonsowman_work> that's alright then

[14:45] <juxta> no roads going that way
[14:46] <juxta> plus a freeway and a highway in the way
[14:46] <jonsowman_work> hmm yes
[14:50] <g8tmv> Helicopter!
[14:53] <LazyLeopard> The dotted lines are 4WD tracks?
[14:56] <juxta> LazyLeopard: sort of.. minor roads really
[14:56] <juxta> most of them are probably passable in a regular car
[14:58] <LA3QMA> this "predict" software is it using WMS ??
[14:59] <jonsowman_work> WMS?
[14:59] <LA3QMA> to "talk" to a mapserver?
[15:01] <LA3QMA> if so i can exchange the googlemap with something better for No(r)way :o)
[15:01] <jonsowman_work> nope
[15:01] <jonsowman_work> it's entirely web based and is hard coded to work with google maps
[15:02] <jonsowman_work> you could download the CSV of the flight path from the predictor tool though
[15:02] <LA3QMA> ahh ok. i can use the WMS thing via googlemap api

[15:11] <jonsowman_work> i could maybe look at implementing that
[15:11] <LA3QMA> i got answer from the "air people". they need 6-7h warning for a "flight plan" and maximum 4.5Kg payload for a balloon
[15:11] <jonsowman_work> i don't know how useful a feature it would be
[15:12] <LA3QMA> jonsowman i'm not using your program som then its probably a waste
[15:12] <LA3QMA> but i have tested it.
[15:13] <LA3QMA> i can use the other maps after an prediction anyhow. your software is more like a tool and using other maps is probably just going to change the focus on whats its suposed to do
[15:14] <juxta> LA3QMA: count yourself lucky, I'm supposed to give 48 hours - 72 hours notice!

[15:18] <LA3QMA> ok the formal paper is saying every 30min or at least the aproximate location. you can even say you lost it and thats ok hehe
[15:19] <juxta> hey jcoxon - i was interested in trying it out, but was also discussing what looks like a bug in fldigi
[15:21] <jcoxon> http://www.pegasushabproject.org.uk/misc/dl-fldigi-3.20.16_setup.exe
[15:23] <juxta> cheers jcoxon
[15:24] <LA3QMA> bbl foodtime
[15:24] <juxta> do you mind if I clear the tracker to test some telemetry strings for tomorrow's flight?
[15:26] <jcoxon> no problem
[15:27] <juxta> cheers
[15:28] <jcoxon> from the changelog for fldigi:
[15:28] <jcoxon> RTTY DSP filter bandwidth tracks baud / shift
[15:28] <jcoxon> Thu Mar 26 16:37:08 2009 -0500
[15:29] <jcoxon> and * Changed s/n & metric filter constants to reduce delay
[15:29] <jcoxon> in first character detection/display.
[15:29] <jcoxon> * Changed initial filter width to 1.3 x baud rate
[15:29] <jcoxon> Mon Jan 25 14:20:14 2010 -0600
[15:30] <juxta> I guess that's it then
[15:32] <juxta> jcoxon: tracker currently shows what I think is the BH custom data fields - is that something I need to speak to Natrium about?
[15:32] <jcoxon> yup
[15:32] <juxta> alrighty
[15:36] <jonsowman_work> where is he anyway

[15:46] <juxta> jcoxon: could you set the name on the tracker to Horus 4?
[15:46] <jonsowman_work> juxta: what time are you launching?
[15:47] <juxta> around 02:00UTC - 03:00UTC
[15:47] <jonsowman_work> cool :)
[15:47] <juxta> perhaps a shade earlier if we get inlfation done quickly

[17:49] <jcoxon> all*
[17:49] <jcoxon> has anyone ever had issues with vista + IE and spacenear.us/tracker
[17:50] <jcoxon> ?
[17:58] <jcoxon> any windows users around?

[18:04] <fsphil> I've got xp on a laptop, but it's rarely loaded up
[18:04] <jcoxon> got someone who says that spacenear.us is broken on his vista box with IE
[18:04] <jcoxon> just wondering if anyone has experienced it
[18:05] <fsphil> I've to walk the dog now, will give it a try when I get back
[18:05] <jcoxon> no worries fsphil, i'm sure it'll work itself out
[18:16] Simon-MPFH (~simon@phantom.mpfh.co.uk) left irc: Quit: Leaving
[18:20] <g8tmv> People might be interested in these http://tinyurl.com/34txrel
[18:20] <fsphil> IE8 / XP seems fine jcoxon
[18:20] <g8tmv> I have bought stuff from this guy before - he's ok
[18:20] <jcoxon> yeah i've got one of these radiosondes
[18:21] <jcoxon> interesting designs
[18:21] <g8tmv> 15 quid incl postage seems pretty good
[18:22] <jcoxon> unfortunately can't launch them :-(
[18:22] <g8tmv> why not?
[18:22] <jcoxon> wrong freq
[18:22] <g8tmv> can't it be tweaked
[18:22] <jcoxon> thats true
[18:22] <g8tmv> or the tx replaced
[18:23] <g8tmv> The GPS and sensors must be worth more than 15 quid
[18:23] <jcoxon> yeah - interesting to tap into the gps - see what type it is
[18:23] <russss> neat
[18:24] <g8tmv> The GPS module looks like it's got 4 connections on the bottom - so Pwr, Gnd, and serial?
[18:25] <jcoxon> most likely
[18:25] <g8tmv> 1200 baud the spec says
[18:26] <g8tmv> Hmm.. their UK office is in Newmarket - easy to visit from Cambridge - I'm sure they would help - it would be good publicity
[18:28] m1x10 (~mixio@ppp089210070036.dsl.hol.gr) joined #highaltitude.
[18:39] <m1x10> jcoxon, what IE+vista issue?
[18:39] <m1x10> jonsowman, give me that link with the todo list of your prediction system
[18:39] <m1x10> Im ready to test it with 5 browsers
[18:41] <jcoxon> m1x10, i'm not really sure - someone says that it stopped working and now just shows a box - i've emailed him with a few things to test to get to the bottom of it
[18:41] <jonsowman> http://github.com/jonsowman/cusf-standalone-predictor/issues/
[18:43] <jcoxon> i've updated the wiki guide to tracking with pics of the new dl-fldigi - could someone check that i haven't missed anything out:
[18:43] <jcoxon> http://ukhas.org.uk/guides:tracking_guide
[18:44] <m1x10> jcoxon, I open with success the tracket site in IE + win7
[18:44] <m1x10> at least I see the main map with the balloon
[18:44] <m1x10> a graph below the map
[18:44] <jcoxon> m1x10, yeah thats it
[18:44] <jcoxon> very strange this error
[18:44] <m1x10> and a box on up right corner
[18:51] <m1x10> jonsowman, opera, safari, chrome works pretty well. I submitted data and with the nice effects it showed me the new predicted path
[18:51] <m1x10> But IE
[18:51] <m1x10> got major problem
[18:52] <jonsowman> yeh IE7
[18:52] <jonsowman> if not others too
[18:52] <jonsowman> i think ironed out some of chrome's bugs a while back
[18:52] <jonsowman> it has a strop with invalid json
[18:53] <m1x10> js/pred.js line 392
[18:53] <m1x10> var newPoly = new google.maps.Polygon({
[18:53] <m1x10> paths: points,

[18:53] <m1x10> remove it
[18:54] <jonsowman> done
[18:54] <m1x10> that last comma instructs IE to wait for another argument
[18:54] <m1x10> ok let me see
[18:55] <m1x10> js/pred.js line 552

[18:55] <m1x10> again
[18:55] <jcoxon> :-)
[18:55] <jonsowman> done
[18:56] <m1x10> ok
[18:56] <m1x10> nice
[18:56] <m1x10> now IE shows everything
[18:56] <jonsowman> excellent :)
[18:56] <jonsowman> thank you m1x10
[18:56] <m1x10> scripting is ok
[18:56] <m1x10> but
[18:56] <m1x10> the boxes
[18:57] <m1x10> dont have that light gray background
[18:57] <m1x10> its transparent
[18:57] <m1x10> so hard to see the letters
[18:57] <m1x10> if u dont understand me I can send you a screenshot
[18:58] <jonsowman> i understand you
[18:58] <jonsowman> hmm
[18:58] <jonsowman> wonder if there's anything that can be done about that
[18:58] <g8tmv> jcoxon: re dl guide
[18:58] <g8tmv> inputted is not a word - it should be input
[18:58] <jcoxon> oops
[18:59] <jcoxon> hehe thanks
[18:59] <jcoxon> good point
[18:59] <g8tmv> also where you mention using a whip maybe you should also mention that because it's omni-directional it will pick up a lot of other signals and noise and the decode will be pretty poor
[18:59] <jcoxon> the images aren't too small?
[18:59] <g8tmv> I'm still checking
[19:00] <g8tmv> Most of the probs that I have are because I don't have a directional antenna and I live on a noisy (RF type) housing estate
[19:00] <m1x10> http://imagebin.org/105449
[19:00] <jonsowman> http://balloon.hexoc.com/gallery/apex-ii/index.php/Case
[19:01] <m1x10> jonsowman,
[19:01] <m1x10> oh cool !
[19:01] <m1x10> omg
[19:01] <m1x10> I want one too
[19:01] <m1x10> :)
[19:01] <jonsowman> m1x10: oh i see the IE issue
[19:01] <jonsowman> intruiging
[19:01] <g8tmv> jcoxon: "Currently it is not possible to resize the height of the dl-fldigi hab but this will be a future addition." needs the word "window" adding
[19:02] <m1x10> jonsowman, what did you use to draw this boxes?
[19:02] <jcoxon> g8tmv, know how you feel, central london makes it a challenge
[19:02] <jonsowman> google sketchup
[19:02] <jonsowman> credit to ben_apex for those :)
[19:03] <g8tmv> jcoxon: "An excellent guide to understanding direction antennas" --- direction should be directional
[19:03] <jcoxon> g8tmv, see why i ask people to check - i type too fast :-p
[19:04] <g8tmv> it's ok I proofread stuf for fandom
[19:06] <jcoxon> hmm i'm wondering -perhaps i should put the r100+ guide above r85
[19:08] <m1x10> jonsowman,
[19:09] <m1x10> the problem is in rgba css property
[19:09] <m1x10> IE8,7,6,5 do not support it
[19:09] <m1x10> IE9 supports it but still beta
[19:09] <jonsowman> ah
[19:09] <m1x10> and not used
[19:10] <Randomskk> lol IE
[19:10] <Randomskk> to be honest though
[19:10] <Randomskk> just don't support IE
[19:10] <m1x10> haha
[19:10] <m1x10> yeah
[19:10] <m1x10> :):)
[19:10] <Randomskk> "hi, you're using IE, it's not supported and there's really no good reason to use it, get a real browser" or suchlike
[19:10] <m1x10> but let me finish it now that I started
[19:10] <Randomskk> hehe yea
[19:13] <g8tmv> jcoxon: is the bit about R85 and r100 still true? isn't it now 3.20.1 or something
[19:14] <m1x10> jonsowman, there is a solution using stupid workarounds for IE
[19:14] <m1x10> some 3-4 lines of code
[19:14] <m1x10> but I suggest
[19:14] <m1x10> just add to the css file
[19:14] <g8tmv> Ha! found a bug - if you try to close the main window using the X and you have a dialog open (like the about box) then it hangs
[19:14] <m1x10> background: rgb(200, 54, 54); /* The Fallback */
[19:14] <m1x10> background: rgba(200, 54, 54, 0.5);
[19:14] <jcoxon> g8tmv, yeah, its a bit confusing - fldigi is 3.20.16 but are revision of dl-fldigi is r100+
[19:14] <jcoxon> are-> our
[19:15] <jcoxon> as in r111 currently
[19:15] <m1x10> let me know when u r done so to check it
[19:15] <g8tmv> well it doesn't say r100+ anywhere in the about box or in the startup logging
[19:15] <jcoxon> g8tmv, thats a good point
[19:16] <jonsowman> m1x10: ok give me a few minutes
[19:16] <jonsowman> very busy at the moment
[19:16] <m1x10> k
[19:18] <jonsowman> jcoxon: could you verify http://robertharrison.org/listen/apex.xml ?
[19:18] <jcoxon> g8tmv, i've changed it a bit - is that clearer?
[19:18] <jonsowman> dl-fldigi is decoding some packets but not verifying and uploading them
[19:18] <g8tmv> jcoxon: changed what?
[19:18] <jcoxon> the titles in the guide
[19:19] <jcoxon> jonsowman, example string please and i'll test it
[19:19] <g8tmv> jcoxon: yes, much clearer

[19:26] <fsphil> can you capture a sample?
[19:26] <jcoxon> yeah sample would be good
[19:26] <jonsowman> ok will do
[19:26] <m1x10> jonsowman, you destroyed something
[19:26] <jonsowman> oh dear
[19:27] <jonsowman> seems ok here
[19:28] <fsphil> any php gurus know why file_get_contents("php://input") isn't showing any data, but $_REQUEST is populated fine?
[19:28] <m1x10> jonsowman, no you got problems
[19:28] <jonsowman> m1x10: fine here on ff 3.6
[19:29] <m1x10> im talking about IE only
[19:29] <jonsowman> oh ok
[19:29] <m1x10> other browsers are fine
[19:29] <jonsowman> hmm
[19:29] <jonsowman> has the above fixed not solved it?
[19:29] <m1x10> the rbga problem was only for IE. dont confuse.
[19:30] <jonsowman> i thought that was a fix for IE?
[19:30] <m1x10> now, what you did about rgba didnt fixed anything.
[19:31] <m1x10> undo your last changes
[19:31] <jonsowman> done

[19:36] <fsphil> yes, both decode here
[19:36] <m1x10> oops sory
[19:36] <jcoxon> and uploaded
[19:38] <jonsowman> hmm
[19:38] <jonsowman> issue with Matt_soton's system then
[19:39] <m1x10> still the boxes are not shown in IE
[19:39] <m1x10> did u do the rgb in the css?
[19:39] <jonsowman> i did
[19:39] <jonsowman> it's back to how it was at the moment
[19:40] <m1x10> i dont see any fixed
[19:40] <m1x10> .box {
[19:40] <m1x10> background:none repeat scroll 0 0 rgba(255, 255, 255, 0.75);
[19:40] <m1x10> }
[19:40] <m1x10> do it
[19:40] <m1x10> .box {
[19:40] <m1x10> background:none repeat scroll 0 0 rgba(255, 255, 255, 0.75);
[19:40] <m1x10> }
[19:40] <m1x10> sory
[19:41] <m1x10> add this line --> background:none repeat scroll 0 0 rgb(255, 255, 255);
[19:41] <m1x10> above the other one
[19:41] <jonsowman> ok in a minute
[19:41] <jonsowman> this fldigi problem is priority at the moment :)
[19:43] <m1x10> for light gray color
[19:43] <m1x10> replace 255,255,255
[19:43] <m1x10> with 211,211,211
[19:43] <jonsowman> jcoxon: any way to wipe fldigi settings etc? does it store things in registry/text file etc?
[19:44] <m1x10> background:none repeat scroll 0 0 rgb(211, 211, 21);
[19:44] <jcoxon> uninstall?
[19:44] <jcoxon> not really sure - haven't run windows since 98
[19:44] <jonsowman> ok :)
[19:44] <m1x10> LOL
[19:45] <jcoxon> ghastly operating system
[19:45] Action: Randomskk will be bringing his linux netbook tomorrow by the looks of things :P
[19:45] <Randomskk> jonsowman: what kinda time do you think you'll be in guildford?
[19:45] <jonsowman> what time do you finish work?
[19:45] <Randomskk> whenever
[19:45] <jonsowman> 4 at a guess?
[19:46] <jonsowman> i can't really say exactly at the mo
[19:46] <Randomskk> okay
[19:46] <jonsowman> about that time
[19:46] <Randomskk> that'l be fine
[19:46] <jonsowman> maybe 3.30 if we're being efficient
[19:46] <jonsowman> pfft
[19:46] <Randomskk> launch is at "10:00"?
[19:46] <jonsowman> indeed
[19:47] <m1x10> jonsowman, ready?
[19:47] <jonsowman> though the later we leave it the worse the flight path
[19:47] <jonsowman> so we will really aim for 10
[19:47] <Randomskk> why not get in nice and early
[19:47] <Randomskk> 8 or so
[19:47] <Randomskk> we're all in cambs
[19:47] <jonsowman> could do, though at that point the landing is further north
[19:47] <jonsowman> 10 looks about perfect
[19:47] <jonsowman> maybe 9
[19:47] <Randomskk> experience suggests we aim for 9 then
[19:47] <jonsowman> yeh
[19:47] <jonsowman> good idea
[19:48] <jonsowman> i said to ed launch site by 9

[19:52] <jonsowman> but this thing is stuck under a desk with terrible airflow
[19:52] <Randomskk> tbh though it's all about the p180 series cases, <3 my removable hard drive bays, silicone mounts for the drives, separate chambers for psu and motherboard, etc

[19:53] <Randomskk> you say that
[19:53] <Randomskk> the laptop I am now on at work (the old one was suddenly required elsewhere) can barely handle three ssh sessions
[19:54] <Randomskk> I think that's more its graphics card being shit

[20:06] <m1x10> a solar shit :)
[20:06] <Randomskk> well no
[20:06] <Randomskk> you could argue that as a series of cells it was a battery, and some would say panel though usually that's reserved for water heating applications
[20:06] <Randomskk> but I think you'd have a hard time arguing it was a solar shit
[20:07] <jonsowman> haha :D

[20:14] <jonsowman> Randomskk: work go alright?
[20:15] <Randomskk> yea thanks
[20:15] <Randomskk> was good
[20:16] <jonsowman> cool
[20:16] <jonsowman> :)
[20:16] <jonsowman> ive only got 2 weeks left
[20:16] <Randomskk> there's quite an entertaining tension between the one guy, who is all ideas and wants to try stuff now and see what effect this has on the code then is on to the next cool thing it can do
[20:16] <jonsowman> ah
[20:17] <Randomskk> and the other, who wants it all to be well arranged and have proper unit tests and be well written and nice
[20:17] <Randomskk> the first prototypes stuff in perl, the latter writes the c++ and ruby
[20:17] <jonsowman> lol
[20:17] <jonsowman> ah right
[20:18] <Randomskk> mostly, I write C++, then do loads of small python scripts and bash oneliners to get loads of data out of the data and visualise it
[20:18] <Randomskk> they now love gnuplot :P
[20:18] <jonsowman> as they should
[20:22] <m1x10> hey people
[20:22] <m1x10> that's my last project

[21:17] <Randomskk> not really
[21:17] <Randomskk> as an aside, saying "ping all" doesn't really work - when you ping a particular person, it usually highlights their irc so they notice

[21:17] <Randomskk> JSON is a data encapsulation format if anything
[21:18] <m1x10> yes I know :):)
[21:18] <Randomskk> it's used to move data between apps
[21:18] <Randomskk> databases are for storing
[21:18] <Randomskk> XML is another data encapsulation format
[21:18] <m1x10> yes but xml is used to store persistent data
[21:18] <Randomskk> well no
[21:18] <Randomskk> it /can/ be, so can json
[21:19] <m1x10> that's what i mean
[21:19] <Randomskk> xml is used to store maybe configuration data or such
[21:19] <Randomskk> and you can write json data to a file
[21:19] <Randomskk> its main advantage is it that it can be easily parsed by javascript
[21:19] <Randomskk> into an array inside javascript
[21:19] <m1x10> like you write xml data to a file..
[21:20] <m1x10> so we have xml and json formats
[21:20] <m1x10> used to save data in files
[21:20] <m1x10> persistent
[21:20] <Randomskk> mostly json is used to transfer data over network links rather than saved in files
[21:20] <Randomskk> but it can be saved in files, as with anything
[21:20] <m1x10> hmm
[21:20] <m1x10> have you ever heard of NoSQL ?
[21:21] <m1x10> another data storage technic
[21:21] <Randomskk> yes
[21:21] <Randomskk> it has its place
[21:21] <m1x10> "it's a very light database"
[21:21] <m1x10> can hold some GB of information
[21:21] <Randomskk> well
[21:21] <Randomskk> can hold some pb of information
[21:21] <m1x10> and perform very fast processing
[21:21] <Randomskk> facebook use it for all their data, for instance
[21:22] <m1x10> wow, fb uses NoSQL ?
[21:22] <m1x10> really?
[21:22] <Randomskk> it is not as good as sql databases for some data modelling though, so you pick your poison
[21:22] <Randomskk> facebook made one of the main nosql databases
[21:22] <Randomskk> cassandra was made by facebook
[21:22] <m1x10> I though it is for just some gbytes
[21:23] <m1x10> yes cassandra..Personally I have used mongoDB with C#
[21:23] <m1x10> pretty easy to handle
[21:23] <m1x10> used json format

[22:33] <eroomde> they can blend in with the a-level chemistry summer schol
[22:35] <jonsowman> ok so it turns out our telemetry is too long for dl-fldigi :(
[22:36] <Randomskk> surely that's a fairly quick and easy hack
[22:36] <fsphil> pong jonsowman
[22:36] <Randomskk> or is it something more profound
[22:36] <jonsowman> well we could cohp bits out of the telem
[22:36] <jonsowman> but we'd rather not
[22:36] <fsphil> too long?
[22:37] <jonsowman> fsphil: did you get dl-fldigi build working?
[22:37] <jonsowman> yep at 109 chars dl-fldigi won't detect the end of the string and upload
[22:37] <jonsowman> chopping out about 9 chars makes it work
[22:37] <fsphil> ooh err, I'll have a look - sounds like a fixed sized buffer somewhere
[22:37] <Randomskk> oh yea, hacking dl-fldigi won't be great since lots of other people will be running it
[22:37] <Randomskk> compression
[22:37] <Randomskk> save some data on your telem :P
[22:38] <eroomde> not that many people are running the newest dl-fldigi i don't think
[22:38] <fsphil> split telemetry .. one with position, one with sensors :)
[22:38] <jonsowman> fsphil: that would be really annoying for us as we have custom software running for the chase cars
[22:38] <eroomde> the ukhas standard turns in its grave
[22:39] <jonsowman> if it's an easy fix then building a new version would be OK
[22:39] <jonsowman> we just have to advise people to use it
[22:39] <Randomskk> most people are using pre-new dl-fldigi though
[22:40] <jonsowman> i dont know how far back this bug goes
[22:40] <jonsowman> it is definitely in r111
[22:40] <jonsowman> a big thing was made of that release and i think a lot of people will be running it
[22:40] <jonsowman> ie. 3.20.1
[22:41] <fsphil> if the string is longer than 100 (minus the $$CALLSIGN bit) it won't upload it
[22:41] <jonsowman> fsphil: is it an easy fix?
[22:42] <fsphil> looks to be
[22:43] <jonsowman> ok
[22:43] <fsphil> the limit is likely there to stop massive amounts of bad data being uploaded, though a small increase should be fine
[22:43] <jonsowman> we need about 110
[22:43] <jonsowman> maybe 120 to account for some variable length fields
[22:44] <eroomde> how about fix it for everyone in the future
[22:44] jcoxon (~jcoxon@host109-152-221-158.range109-152.btcentralplus.com) joined #highaltitude.
[22:44] <eroomde> so as to prevent this happening the next time someone makes a perfectly legal string that just happens to not work with dl-fldigi
[22:44] <jonsowman> hi jcoxon
[22:44] <eroomde> so make it like 300
[22:44] <jcoxon> eek issues?
[22:44] <jonsowman> yup
[22:45] <jonsowman> telem string is too long for dl-fldigi
[22:45] <fsphil> jcoxon, jonsowman's strings are greater than 100 characters :)
[22:45] <eroomde> dl-fldigi doesn't support the ukhas telemetry standard
[22:45] <jcoxon> how many are they?
[22:45] <jonsowman> 110 ish, maybe 120
[22:45] <jcoxon> hehe
[22:45] <eroomde> although that's perhaps an isue with the standard becuase it doesn't stop you making 1000000-char strings
[22:45] <jonsowman> but as eroomde said, putting the limit as 300 is probably more sensible
[22:45] <fsphil> or 200
[22:45] <Randomskk> 256?
[22:45] <jonsowman> yes
[22:45] <jonsowman> Randomskk: trust you
[22:46] <fsphil> if you need more than 200, you're doing it wrong :)
[22:46] <Randomskk> I like powers of two really

[22:47] <jcoxon> remember the original strings were just lat/lon and alt
[22:47] <jcoxon> :-p
[22:47] <fsphil> ah simpler times ;-)
[22:47] <sbasuita> use a std::string instead of an array?
[22:47] <eroomde> yep. then we started doing things that were more interesting
[22:47] TraumaPony (~TraumaPon@124-171-137-179.dyn.iinet.net.au) joined #highaltitude.
[22:48] <jcoxon> well lets just roll a new binary
[22:48] <jcoxon> its about time we did 112 anyway
[22:48] <Randomskk> oh, man, I hate it when things that work reliably and fine at 5v break totally at 3v
[22:48] <fsphil> 200 is a good compromise
[22:48] <fsphil> until something better can be figured out
[22:49] <Randomskk> i.e., until someone needs more than 200?
[22:49] <Randomskk> :P
[22:49] <jonsowman> could the limit be put in the flight xml
[22:50] <eroomde> quite complicated to do that on a per-flight basis when 99.9% of the time the value is just a default
[22:50] <eroomde> i.e. 200

[22:52] <jonsowman> we only need OS X and Windows

[22:52] <Randomskk> theoretically
[22:52] <eroomde> what about the rest of us?
[22:52] <fsphil> good idea jcoxon
[22:52] <Randomskk> other people might be tracking and running linux
[22:52] <jonsowman> true
[22:52] <jonsowman> thats what i was about to say

[22:52] <Laurenceb> like me
[22:52] <jonsowman> indeed
[22:52] <eroomde> and me
[22:53] <jonsowman> anyway i'll mention it in the launch announcement
[22:53] <jcoxon> well get linux debs out
[22:53] <fsphil> can you pull the latest changes from my branch before you make the new release, it's got the image upload stuffs
[22:53] <jcoxon> yes
[22:54] <jcoxon> i don't really see another solution
[22:54] <jcoxon> you could easily shave off chars but shortening your callsign
[22:54] <jcoxon> but i guess thats not enough
[22:54] <jcoxon> and its best not mess with hte payload
[22:54] <fsphil> the callsign doesn't count towards the uploaded string
[22:55] <fsphil> oh wait it does
[22:55] <jcoxon> okay so are people happy with new binaries tomorrow morning
[22:55] <jcoxon> gives you 24hrs to install :-p
[22:56] <eroomde> can they have vanilla names?
[22:56] <eroomde> (bee in bonnet)
[22:56] <jcoxon> will try
[22:56] <jonsowman> sorry to be annoying but we'd rather not trim the telem
[22:57] <eroomde> you're sticking to the standard - you shouldn't have to start messing with firmware. might be worth ammednin the standard thought, to include a length limit
[22:58] <jcoxon> pah few people stick to the true standard
[22:58] <jcoxon> :-p
[22:58] <Randomskk> is there even a 'true' standard

[23:03] <eroomde> which would just pick out the strings that were his payload
[23:03] <eroomde> not that i'm volunteering to implement it so i'll shurdurp

[23:05] <eroomde> ok, night all. will check in tomorrow jonsowman - or perhaps it'd be better to call me on my phone if you need anything
[23:05] <Randomskk> seeya
[23:05] <eroomde> also, it's going east - there's no particularly good spot at churchill from which to track, you should know
[23:05] <jonsowman> eroomde: thanks
[23:06] <eroomde> (CUED roof is no longer available to us)
[23:06] <jonsowman> will give you a ring tomorrow to check everything

[23:06] <eroomde> fine, not a prob then
[23:06] <jcoxon> jonsowman, full sample string please
[23:06] <RocketBoy> Just so everyone knows - I have a couple of groups launching form EARS on Saturday
[23:06] <jcoxon> a couple?
[23:06] <jonsowman> jcoxon: coming up

[23:09] <RocketBoy> the rocket gut has made a tracker - I'll get details - but its not very dl-fldigi friendly (i think its just nmea strings)

[23:09] <jcoxon> you know we might actually be able to cope with nmea

[23:16] <RocketBoy> the other is just SMS
[23:17] <Laurenceb> SMS with a phone or module?
[23:17] <RocketBoy> modu
[23:17] <Laurenceb> ah
[23:17] <RocketBoy> a tracker - £45 on ebay (new)
[23:18] <RocketBoy> clip on your belt thing
[23:18] <RocketBoy> makes it all too easy IMO

[23:33] <eroomde> jonsowman has stated 09:00 to 10:00
[23:33] <RocketBoy> (its not up to me really - its when they turn up)
[23:33] <eroomde> well it sounds like something needs a budge as otherwise there'll be a clash
[23:34] <eroomde> unless we're lucky and are a couple of khz out - but temp drifts usualy mean they'll probably co-incide at some point
[23:34] <RocketBoy> yeah
[23:35] <RocketBoy> jonsowman: have yo got another module on .650?
[23:36] <RocketBoy> (im asking the same Q of the other guy)
[23:37] <RocketBoy> he hasn't got another module
[23:37] <Matt_soton> we're 074
[23:37] <Matt_soton> 5
[23:37] <Matt_soton> only one module
[23:38] <jonsowman> RocketBoy: it's an NiM2, not a normal NTX2
[23:38] <jonsowman> so no, we only have the one module
[23:38] <jonsowman> sorry
[23:41] <RocketBoy> yeah - he hasn't got another module either - I have a .650 NTX2 - but i'm not sure hell want to do any last min soldering
[23:41] <RocketBoy> (Im asking)
[23:41] <jonsowman> OK
[23:41] <jonsowman> we are happy to reimburse the cost of your NTX2
[23:42] <RocketBoy> oh don't worry - I'll probably get it back

[23:43] <jcoxon> do you have a mac system in front of you?
[23:43] <jonsowman> i do
[23:43] <jonsowman> i dont have a payload though
[23:43] <jonsowman> got a binary?
[23:43] <Randomskk> you have the audio though?
[23:43] <jonsowman> true
[23:44] <Randomskk> grr. my capacitive touch sensing doesn't work on 3v
[23:44] <Randomskk> need to either write that in asm and hope it'l work, rewrite it to use the ADC instead of the digital input, or get more volts
[23:44] <jcoxon> http://www.pegasushabproject.org.uk/misc/dl-fldigi-3.20.16-r112.dmg
[23:45] <jcoxon> so i've kept the default limit as 100
[23:45] <jcoxon> but now it checks for an xml_stringlimit
[23:45] <jcoxon> which is defined in the xml
[23:45] <jcoxon> if that is more then the default 100 it uses that instead
[23:47] <jonsowman> whereabouts in the xml should that go?
[23:47] <jcoxon> its in place already
[23:47] <jcoxon> http://www.robertharrison.org/listen/apex.xml
[23:47] <jonsowman> brilliant :D
[23:47] <jonsowman> thank you very much
[23:47] <jcoxon> needs to be tested
[23:47] <jcoxon> i didn't have any audio to test it with
[23:48] <jonsowman> Matt_soton: new audio of packets?
[23:49] <Matt_soton> comming...
[23:49] <jonsowman> thanks
[23:49] <jonsowman> RocketBoy: any news?
[23:51] <RocketBoy> na - he has gone quiet at the suggestion of soldering in a new module prior to launch
[23:52] <Randomskk> could make for an interesting time if we end up with coinciding signals
[23:52] <jcoxon> i flew 2 radiometrix .075 on BH5
[23:52] <jcoxon> not the end of hte world
[23:52] <eroomde> it depends
[23:53] <eroomde> if they're sufficiently far then fine, and if they're on the same payload then they'll be in vaguely similar themral environments
[23:53] <jcoxon> oh eroomde i've done what you asked :-p
[23:53] <eroomde> but if one is at 20 degrees whilst th other is at -20, and that swaps around at some point, there's likely to be a collision
[23:53] <jcoxon> on the new binary
[23:54] <Randomskk> if we're lucky they'll fly in different directions slightly
[23:54] <eroomde> or worst of all, they could just both be too close to each other for more or less the entire time
[23:54] <eroomde> did anyone publicaly call first dibs on a saturday launch?
[23:54] <Randomskk> depends on how public you want I guess
[23:54] <eroomde> Randomskk: most people have whips or yagis that face vaguely towards east anglia - that's not going to help much
[23:54] <RocketBoy> I guess this is one for the learning books - we should sort the multiple tx on the same freq issue
[23:55] <eroomde> i would suggest the above
[23:55] <eroomde> as trying to test both to ensure there'll not get more than say a khz close to each other is fairly impractical
[23:57] <jonsowman> hopefully we can switch the other payload to .650
[23:57] <jonsowman> that'd be the best solution
[23:57] <eroomde> agreed
[23:58] <eroomde> or we knoock up oppositely polarised antennas on the payloads and get every single listener to make an antennaof the polarisation of the payload that they're interested in
[23:58] <RocketBoy> yeah this is problamatic - I cant really be responsible for co-ordinating frequencies of everyone who wants to fly from EARS - and if the guy shows no interest in getting involved in #highaltitude and ukhas its up to him down to
[23:58] <eroomde> don't all shout at once
[23:58] <Randomskk> jonsowman: anything I need to bring for tomorrow?
[23:59] <jonsowman> not really. laptop might be handy
