[00:18] <juxta> anybody still up?
[00:18] <natrium42> hi Mr. Endeavour
[00:18] <natrium42> hi Dr. juxta
[00:18] <Endeavour> The Natrium
[00:18] <juxta> hey natrium42 :)
[00:18] <natrium42> any luck with the permission?
[00:18] <juxta> I just got a call from CASA, we're pretty much good to go!
[00:19] <natrium42> yay
[00:19] <juxta> they just want to use the tracker and follow the flight
[00:20] <juxta> now to see what predictions look like...
[00:21] <natrium42> bbl food
[00:21] <juxta> natrium42: when you're back, I was going to ask you - mind if we have our chase cars post their positions on the tracker?

[00:32] <Endeavour> How many folks here have launched a balloon?
[00:34] bt42 (n=User@unaffiliated/bittwist) left irc: No route to host
[00:42] <SpeedEvil> prolly about 10 total here - most are asleep
[00:42] <SpeedEvil> ayee all
[00:46] <juxta> hi SpeedEvil
[00:46] <SpeedEvil> hi
[00:47] Action: juxta got approval :D
[00:48] <SpeedEvil> Woo!
[00:49] <juxta> finally
[00:49] <juxta> only condition being that they get the url for the tracker
[00:49] <SpeedEvil> What's the total damages on the approval process?
[00:49] <juxta> $240 I think
[00:49] <juxta> haven't received any new invoices
[00:49] <juxta> so hopefully there's no further cost
[00:50] <natrium42> juxta, why would i mind, that would be very cool :)
[00:51] <juxta> alright - cool, I'll work on it natrium42
[00:51] <juxta> doesnt look like I can launch for a while in any case, weather is not good
[00:51] <natrium42> let me know if you have any questions/problems
[00:51] <natrium42> ah
[00:51] <natrium42> doesn't australia have perfect weather?
[00:52] <juxta> well it'll be sunny etc
[00:52] <juxta> but the winds will blowing in the wrong direction according to the CUSF predictor
[00:52] <juxta> (I live on the coast)
[00:53] <natrium42> right, don't want it to get into the ocean
[00:55] <juxta> outside of the ocean would be ideal :)
[01:28] <SpeedEvil> how accurate has the predictor been ?

[07:41] <juxta_> hey natrium42, you about?
[07:41] <natrium42> yo
[07:41] <juxta_> I got approval for my launch today :)
[07:41] <natrium42> yah, congrats
[07:41] <juxta_> part of the deal is that they can follow the launch via the tracker
[07:42] <juxta_> I gave them the url spacenear.us
[07:42] <juxta_> (without /tracker)
[07:42] <natrium42> oh, should i put a link there?
[07:42] <juxta_> is there a chance that we could put a link just before I launch?
[07:42] <natrium42> sure, i will do that
[07:42] <juxta_> cheers :)
[07:47] <juxta_> natrium42: How about if I send you an email with the date once we have it so you can put the link up just before we launch?
[07:47] <natrium42> i already added it
[07:47] <juxta_> ah, it's already there :)
[07:48] <natrium42> :)
[08:02] <natrium42> juxta_, i added a link to your site
[08:02] <natrium42> let me know if you want to add anything to the tracker
[08:04] <natrium42> should it be just HORUS or PROJECT HORUS as on your blog?
[08:09] Simon-MPFH (n=simon@phantom.mpfh.co.uk) joined #highaltitude.
[08:15] <juxta_> natrium42: horus is fine, or project horus
[08:15] <juxta_> doesnt bother me :)
[08:16] <natrium42> it's up to you
[08:16] <russss> it's all about the branding
[08:16] <russss> :P
[08:16] <natrium42> do you want me to enable twitter?
[08:16] <natrium42> you could tweet from the field :P
[08:17] <juxta_> natrium42: yeah, twitter would be nifty
[08:17] <juxta_> shall I use the UKHAS account?
[08:18] <natrium42> i can point it at yours
[08:18] <natrium42> what's your twitter name?
[08:21] <juxta_> I dont have one ;)
[08:22] <juxta_> I'll set one up for horus though
[08:36] <juxta_> natrium42: as it turns out I do have an account which I used some time ago
[08:37] <juxta_> anyway, I changed the username etc, it's now project horus
[08:37] <juxta_> sorry, 'projecthorus'
[08:37] <natrium42> ok, added
[08:42] <natrium42> i can also turn on video streaming if you want :P
[08:44] <juxta_> haha, video of what? ;p
[08:44] <natrium42> live webcast
[08:45] <natrium42> i have a ustream.tv widget that i can enable :P
[08:45] <juxta_> heh
[08:45] <natrium42> laptop and cellular broadband is all you need
[08:45] <juxta_> dont think we'll have reliable enough internet access in the field for that
[08:46] <juxta_> 3g coverage here is patchy
[08:47] <juxta_> actually, I'll take my laptop and mobile broadband out to the launch site this weekend perhaps
[08:48] <juxta_> and see if I do get 3g coverage there - but I doubt it - I know that a few hundred meters away I only get GPRS coverage
[08:50] <natrium42> it's similar to canada then
[08:50] <natrium42> once you get out of populated area, you're lucky to have regular cellphone connection
[08:50] <natrium42> anyway, bed time for me

[23:18] <Laurenceb> SpeedEvil: the code was a little dodgy - basically I was trying to do newtons method

[23:18] <Laurenceb> using some dodgy vector stuff that failed miserably
