[10:19] <fsphil> ntx2 from previous flight is working again! straightened out all the pins, one had broke off but a quick solder and all is good. the case still has a big dent in it. not sure if I should fly it again
[10:21] <DanielRichman> a dent!?
[10:22] <DanielRichman> did you have a crash landing?
[10:22] <jonsowman> i think most HAB landings are probably crash landings
[10:22] <jonsowman> the things don't have the easiest of times when they hit the ground
[10:25] <fsphil> yea the balloon and parachute got tangled .. it landed with a thud
[10:25] <fsphil> http://www.sanslogic.co.uk/hadie/hadie-after.jpeg
[10:26] <jonsowman> ouch
[10:26] <DanielRichman> :'(
[10:26] <jonsowman> aw
[10:26] <fsphil> only the crystal was holding those two bits together :)
[10:26] <jonsowman> anyway it lives
[10:26] <jonsowman> haha
[10:26] <fsphil> amazingly everything works
[10:26] <jonsowman> nice
[10:27] <fsphil> even the crystal
[10:27] <jonsowman> :)
[10:27] <jonsowman> another flight soon then?
[10:27] <fsphil> aye aye
[10:27] <DanielRichman> is the lump of metal front centre stage the remains of the ntx2?
[10:27] <jonsowman> fsphil: good to hear
[10:27] <fsphil> end of july / early august
[10:27] <jonsowman> i look forward to it :)
[10:28] <fsphil> then another in September -- cause one is never enough :)
[10:28] <jonsowman> :D
[10:28] <jonsowman> anyone around with Chrome installed?
[10:28] <DanielRichman> hi
[10:28] <jonsowman> http://www.hexoc.com/hab/predict/predict/
[10:28] <DanielRichman> yeah I have chrome installed (Ubuntu)
[10:28] <fsphil> DanielRichman, yea that's the ntx2
[10:28] <DanielRichman> fsphil, :o
[10:28] <jonsowman> does the drop down launch site list have stuff in it?
[10:29] <jonsowman> should be like Churchill, EARS, etc
[10:29] <DanielRichman> when I click the drop down the whole box jumps top right
[10:29] <jonsowman> oh god
[10:29] Action: DanielRichman inspects element
[10:29] <DanielRichman> no it has nothing in it either
[10:29] <DanielRichman> sorry :(
[10:29] <jonsowman> damn
[10:29] <jonsowman> chrome being annoying
[10:29] <jonsowman> works fine in every other browser
[10:29] <jonsowman> cannot work out why
[10:30] <DanielRichman> hmm when I click it and it jumps if I alttab in and out it's like my mouse is dragging the whole box around
[10:30] <jonsowman> that box is meant to be draggable
[10:30] <jonsowman> if you just click and drag it, should work
[10:30] <DanielRichman> indeed it does
[10:30] <jonsowman> it should not, however, just wander off of its own accord :\
[10:31] <DanielRichman> s/top right/top left/
[10:31] <jonsowman> bizarre
[10:31] <jonsowman> i must continue packing, i shall continue bugfixing later
[10:31] <jonsowman> silly chrome.
[10:33] <jonsowman> cheers DanielRichman
[10:33] <DanielRichman> jonsowman, if I run $("<option>").attr("value", "Other").text("Other").appendTo("#site"); in the "Javscript Console" it gets an item
[10:33] <jonsowman> :\
[10:33] <DanielRichman> however if I run populateLaunchSite then it is emptied and nothing added
[10:33] <jonsowman> and $("#site > option").remove();
[10:34] <jonsowman> weird
[10:34] <jonsowman> it should fire off an ajax GET request for sites.json
[10:34] <DanielRichman> lemme start wireshark
[10:34] <jonsowman> thanks :) don't worry if you're busy or anything
[10:35] <DanielRichman> the request for that json returns a HTTP/1.1 304 Not Modified
[10:35] <jonsowman> seems right
[10:36] <DanielRichman> and if I clear the cache it's a standard HTTP 200 + data yet still nothing fills the box
[10:36] <jonsowman> hmm
[10:36] <jonsowman> so confused
[10:37] <DanielRichman> ahaa!!! I can set breakpoints
[10:37] <DanielRichman> that makes it easier
[10:37] Action: DanielRichman tries again
[10:44] <DanielRichman> jonsowman, I can't be sure but I don't think getJSON is calling the function that deals with the result;
[10:45] <jonsowman> that's even weirder
[10:45] <Randomskk> shove an alert or something in it
[10:45] <jonsowman> ok
[10:45] <DanielRichman> I put a breakpoint inside the nested function and it never triggered; but that might be an oddity of the debugger
[10:46] <jonsowman> try now :)
[10:46] <Randomskk> no alert
[10:46] <Randomskk> firefox does
[10:46] <jonsowman> :\
[10:46] <DanielRichman> no alert :(
[10:47] <jonsowman> right well that's why it's not working ha
[10:47] <DanielRichman> try using $.ajax rather than $.getJSON? 'cause you're using that later on in the script and that seems to work
[10:47] <jonsowman> yeh i will do that
[10:47] <jonsowman> in a bit. must not get distracted from packing
[10:47] <jonsowman> or too distracted, at least
[10:47] <DanielRichman> :P
[10:49] <DanielRichman> jonsowman, later also there's blue borders on 2 sides out of four of the bottomright box
[10:50] <jonsowman> oh yes
[10:50] <jonsowman> been meaning to sort that out for ages
[10:50] <jonsowman> cheers
[10:51] <jonsowman> it looks good like that when it's in the bottom right. but since it can move, probably not a good idea
[10:51] <Randomskk> more importantly predictions don't appear to be working?
[10:51] <jonsowman> what's happening
[10:51] <jonsowman> does it look like it's hanging at 0%?
[10:51] <Randomskk> yea
[10:51] <Randomskk> no
[10:51] <jonsowman> it will work
[10:51] <Randomskk> it just got to 10%
[10:51] <jonsowman> just takes forever
[10:51] <Randomskk> blimey
[10:52] <Randomskk> what happened
[10:52] <jonsowman> i dont know
[10:52] <jonsowman> dods server being really slow
[10:52] <Randomskk> ah
[10:52] <jonsowman> i ran the hourly preds grabber manually
[10:52] <jonsowman> took an hour and a half for deltas of 3
[10:52] <Randomskk> !
[10:52] <jonsowman> yeh
[10:52] <jonsowman> don't know what's going on
[10:53] <Randomskk> seems a tad faster now
[10:53] <jonsowman> nothing has been changed in predict.py so i don't think it could be our end anyway
[10:53] <Randomskk> taking about 3min, so far 70% and 50s left
[10:54] <jonsowman> yeh
[10:55] <jonsowman> dont know whats happened to make it so slow

[10:58] <Randomskk> uhm
[10:58] <Randomskk> no idea
[10:58] <Randomskk> they are?
[10:58] <Randomskk> brunch isn't for 30min
[10:58] <Randomskk> who is everyone
[10:58] <jonsowman> most of cripps it appears
[10:58] <jonsowman> loads of people
[10:58] <jonsowman> :\
[10:58] <Randomskk> wx is a bit shit
[10:58] <Randomskk> no idea
[10:58] <jonsowman> yeh
[10:58] <jonsowman> weird
[10:59] <Randomskk> getting ready for brunch early?
[10:59] <Randomskk> dunno
[10:59] <jonsowman> pretty early
[10:59] <Randomskk> yea

[11:01] <jonsowman> now theyre all being quiet
[11:01] <jonsowman> and gathered round
[11:01] <jonsowman> listening to someone speak
[11:01] <sbasuita> live stream?
[11:01] <sbasuita> ;P
[11:02] <Randomskk> who's speaking
[11:02] <jonsowman> dont know
[11:02] <jonsowman> sbasuita: lol
[11:02] <jonsowman> i think it might be JCR elections or something?
[11:02] <jonsowman> i have a habit of automatically deleting JCR emails
[11:06] <Randomskk> jonsowman: modified nerf belt to get spacing correct, now feeds all 75 by itself
[11:06] <Randomskk> from http://sphotos.ak.fbcdn.net/hphotos-ak-snc3/hs542.snc3/29729_399638184402_589074402_4299865_5115742_n.jpg setup, I can just hold the trigger and they all go
[11:07] <Randomskk> no hand feeding required
[11:07] <jonsowman> heheheheh
[11:07] <jonsowman> :D :D
[11:10] <Randomskk> also I can get it to fire the first round
[11:10] <Randomskk> so in total 74
[11:11] <jonsowman> haha
[11:12] <DanielRichman> what. is. that.

[11:13] <Randomskk> DanielRichman: nerf ebf-25 full auto machine gun with tripod and belt feed, with three belts chained together for a 75 round capacity
[11:13] <DanielRichman> :O
[11:13] <DanielRichman> Randomskk, with webcam and face recognition software duct taped to the top?
[11:14] <Randomskk> haha great minds think alike
[11:14] <Randomskk> the servos are already in the post from home so I can rig it to my laptop
[11:14] <DanielRichman> that's awesome
[11:14] <Randomskk> planning on using motion (linux) to do it
[11:14] <Snomi> how far does it shoot?
[11:14] <Randomskk> that way having it record videos is easy
[11:15] <Randomskk> plus a python script to talk to the arduino to send the fire commands, also something to upload videos to youtube, also something to play Portal turret sounds
[11:15] <Randomskk> Snomi: far enough, maybe 10m
[11:15] <DanielRichman> hahaha
[11:15] <Snomi> portal turrts
[11:15] <Snomi> urgh
[11:15] <Randomskk> it doesn't use compressed air, just mechanically smacks the back of the nerfs
[11:15] <Snomi> shouldnt have been in the game
[11:15] <Snomi> they were poor
[11:15] <Randomskk> they were awesome D:
[11:15] <DanielRichman> portal turrets were one of the best bits!
[11:15] <Snomi> the game was great up until the turrets
[11:15] <Snomi> let's be fair
[11:16] <Snomi> it was good until shooting came into it
[11:16] <Randomskk> DanielRichman: plan is to leave it in the corridor outside, where it's far enough from the door that it'l hit you, but the scatter is such that you can't avoid it
[11:16] <Randomskk> should be epic
[11:16] <Snomi> should have stayed as bare mind blowingness
[11:16] <Snomi> with the portals
[11:16] <Randomskk> fire off three shots per detected motion event is my plan, gives 25 detected events before a reload
[11:16] <DanielRichman> Randomskk, I almost expected you to attach it to the ceiling
[11:16] <Snomi> O_e
[11:16] <Randomskk> I'm tempted
[11:16] <Randomskk> but it's harder
[11:16] <Randomskk> the ceiling tiles here do come up though, so I may try hiding it in there and pointing it down
[11:17] <Snomi> how big is it?
[11:17] <Randomskk> but it has a tripod so
[11:17] <sbasuita> Randomskk: needs a 24/7 ustream with twitter alerts
[11:17] <Randomskk> hahaha
[11:17] <DanielRichman> or have a ceiling tile that flips
[11:17] <Randomskk> it does in fact need ceiling alerts
[11:17] <Randomskk> DanielRichman: the porters would not be pleased if I mod the ceiling too much
[11:17] <Randomskk> actually they will not be pleased anyway

[11:17] <Randomskk> bigish
[11:18] <Randomskk> ~70cm end to end
[11:19] <DanielRichman> you could let people control it over the net with live stream :P
[11:19] <sbasuita> shotgun
[11:20] <jonsowman> haha
[11:20] <Randomskk> haha net control would be awesome
[11:21] <Randomskk> but I really want a python state machine with portal turret sounds on transitions
[11:21] <Randomskk> "where are you?"
[11:21] <Randomskk> "there you are!"
[11:21] <Randomskk> "dispending product"
[11:21] <Randomskk> dispencing* even
[11:21] <Randomskk> "I can't see you!"
[11:21] <sbasuita> i might be tempted to turn it round and start shooting you in the middle of the night ;P
[11:21] <Randomskk> allow motorised mount control
[11:21] <Randomskk> you get fire and that's it :P
[11:21] <sbasuita> ;(
[11:22] <Randomskk> jonsowman: brunch?
[11:22] <jonsowman> yeh
[11:22] <jonsowman> be down in a sec
[11:23] <DanielRichman> add an accelerometer for the "Put me down" clip

[12:25] <fsphil> just watching this video: http://www.youtube.com/watch?v=nojl3aiYBOw
[12:26] <fsphil> they mention they're wearing gloves to stop getting any sweat on the balloon, which would freeze. that a possibility?
[12:26] <SpeedEvil> It's irrelevant
[12:27] <SpeedEvil> balloons often go through clouds on the way up
[12:27] <SpeedEvil> it does not affect the altitude - it freezes and cracks off
[12:28] <fsphil> right, hadn't thought of the clouds
[12:28] <SpeedEvil> It's probably not a bad plan from the POV of fingernails, which may have unnoticed jaggy bits on.
[12:29] <fsphil> they also twist the neck to seal it
[12:48] cuddykid (~acudworth@78.147.212.0) joined #highaltitude.
[12:54] <cuddykid> Hi all, something weird has happened to my yaesu ft-817 :S .. for some reason it no longer has that faint crackling/background noise when scanning around instead its just dead silence. It picks up the NTX2 only when close by and its absolutely clear/precise, when I move away I just get the silence again :S .. does anyone know what could be wrong?
[12:55] <jonsowman> squelch turned up too high?
[12:55] <cuddykid> thats the knob on the right?
[12:55] <cuddykid> the sound volume one?
[12:55] <jonsowman> i dont know the 817, sorry
[12:55] <jonsowman> have a look in the manual for squelch control
[12:56] <cuddykid> urm, I don't think so, because I haven't changed any of the settings but it just started doing it when I switched over to using it on batteries, but now its even doing it when plugged into mains :S
[12:56] <cuddykid> i'll have a look!
[12:56] <SpeedEvil> Squelch is a control that mutes audio when there is under a predefined threshold of signal.
[12:56] <jonsowman> how strange
[12:56] <SpeedEvil> :/
[12:56] <cuddykid> that sounds like the problem
[12:57] <cuddykid> hmm, i'll have a look in the manual
[12:57] <sbasuita> cuddykid: its the outer ring on the volume iirc
[12:57] <sbasuita> cuddykid: should be marked SQL
[12:57] <cuddykid> thanks, sbasuita, will have a look..
[12:57] <sbasuita> yeah on the bottom right
[12:58] <cuddykid> brilliant! sorted it! thanks guys
[12:58] <sbasuita> twist it all the way counter clockwise
[12:58] <sbasuita> :)
[12:58] <cuddykid> didn't even notice the one underneath! must have accidentally twisted it!
[12:58] <jonsowman> :)
[12:58] <sbasuita> yeah its nice to leave on so you don't get a static headache
[12:58] <cuddykid> yeah!
[12:59] <DanielRichman> also saves power SQLched
[12:59] <DanielRichman> iirc
[12:59] <cuddykid> it must have been set too high because unless it was basically full signal it was dead silent
[12:59] <jonsowman> yeh just set it high enough so you hear the rtty but kill the static when it's not transmitting
[12:59] <cuddykid> DanielRichman, good! Seems to drain the 8AA batteries quite quick!
[13:00] <DanielRichman> eh the 817 should come with a pretty good internal
[13:00] <DanielRichman> and a power adaptor
[13:00] <jonsowman> i thought the internal 817 pack was known to be awful
[13:01] <cuddykid> it might be the batteries i'm using, they were just cheap ones i found! I've got a stack of lithiums for the launch so will put them in for the real thing!
[13:01] <sbasuita> DanielRichman: dude the battery we had on the 817 was awful
[13:01] <jonsowman> sbasuita: yep i thought it was known to be terrible
[13:02] <cuddykid> i think the current draw is quite high on the 817
[13:03] <DanielRichman> sbasuita, it wasn't that bad...
[13:05] <cuddykid> time to get my lassen iq connected up to the arduino! Does anyone know if theres any schematics to aid me?!

[14:38] <sbasuita> ;P
[14:38] <rjharrison> Only EMC to learn then 4 days of HAM tests and revision
[14:57] <jonsowman> rjharrison: didn't know anything about a CUSF NOTAM yesterday
[14:58] <rjharrison> jonsowman apparently it was on the t'internet
[14:58] <rjharrison> I'v asked for the link
[14:59] <jonsowman> interesting
[15:02] <rjharrison> I think they may have been confused between the NOTAM and actual release information
[15:02] <rjharrison> As I understand in the NOTAM is in place constantly
[15:02] <rjharrison> s/in/it
[15:02] <jonsowman> well yes
[15:03] <jonsowman> we don't need to apply for them on a per launch basis
[15:03] <jonsowman> we just ring Cambridge tower to make sure we're OK to launch
[15:03] <rjharrison> So I guess someone looking at todays NOTAMS for cambridge may think that there is a launch planned
[15:03] <rjharrison> Yep
[15:04] <jonsowman> yes that's potentially what happened
[15:04] <jonsowman> I'm pretty sure there were no CUSF launches yesterday
[15:04] <rjharrison> I'm hoping to get a 6 month rolling NOTAM from York on a 24/7 basis
[15:04] <jonsowman> fair enough
[15:05] <jonsowman> hows the hourly predictor doing
[15:05] <jonsowman> the NOAA NOMADS server is being extraordinarily slow the last few days
[15:07] <rjharrison> jonsowman Working a treat
[15:08] <rjharrison> Now that you sorted the cron rentries
[15:08] <jonsowman> good good :)
[15:08] <rjharrison> goign to a 5by5 grid made a huge difference too
[15:08] <jonsowman> yes it really does
[15:08] <jonsowman> 10x10 isn't necessary
[15:09] <rjharrison> jonsowman, unless you are going trans-continental
[15:10] <jonsowman> that's true
[15:10] <jonsowman> the new CUSF predictor will allow massive deltas
[15:10] <jonsowman> http://www.hexoc.com/hab/predict/predict/
[15:10] <jonsowman> at the moment you can only select 3/5/10 but the system is in place for a trans-atlantic prediction
[15:13] <rjharrison> jonsowman, wow I really like that
[15:14] <jonsowman> rjharrison: thanks :)
[15:14] <jonsowman> still working on it
[15:14] <jonsowman> but it's getting there
[15:14] <rjharrison> Provided I get my notam in place I'll have to get Elvington on the list
[15:14] <jonsowman> yeh can do it now if you like
[15:15] <jonsowman> just need a lat/long/altitude

[15:17] <rjharrison> jonsowman, I have made a request
[15:17] <rjharrison> Does that work?
[15:17] <jonsowman> yup :)
[15:17] <jonsowman> will do that for you now, 2 secs
[15:18] <rjharrison> jonsowman Thanks
[15:19] <jonsowman> done :)
[15:20] <juxta> hey rjharrison
[15:21] <juxta> good good - have actually had a bit of time in the last couple of days
[15:21] <juxta> though I still havent got a desk chair sorted so I've been sitting on a wooden stool - limiting my time on my pc :)
[15:22] <juxta> ordered a couple of GPS' from Mike yesterday, will get a few NTX2's this week also
[15:24] <juxta> jonsowman: this new predictor looks very smooth!
[15:24] <jonsowman> juxta: thanks :) it's been a reasonable amount of work but I was fed up with the old interface
[15:25] <rjharrison> juxta cool I just got 12 NTX2's from radiometrix
[15:25] <jonsowman> any comments/suggestions etc welcome if you think of any features you want
[15:25] <rjharrison> These are for the school trackers
[15:25] <juxta> jonsowman: what do the delta's do?
[15:26] <rjharrison> jonsowman, is this operational?
[15:26] <jonsowman> the red square on the map - shows the area for which wind data will be downloaded for
[15:26] <rjharrison> Ie is the grib being pulled often enough
[15:26] <juxta> oh wow, v. nice
[15:26] <juxta> when I ran mine rjharrison it looked like it pulled the grib on demand
[15:26] <juxta> showed a progress bar and took ~30 secs
[15:27] <jonsowman> yeh at the moment it doesnt cache gribs
[15:27] <juxta> jonsowman: mind if I request to save some coords? :)
[15:27] <jonsowman> however that's on the todo list - ie. use the gribs that the hourly predictor pulls automatically for UK predictions
[15:27] <jonsowman> juxta: of course not :)
[15:28] <rjharrison> jonsowman, just to be a pain I have made another request on behalf of boston spa school
[15:29] <jonsowman> juxta: done :)
[15:29] <juxta> hmm - seems to have stalled for me, let me try to refresh
[15:29] <jonsowman> oh
[15:29] <jonsowman> rjharrison: that was you - have done Boston Spa
[15:29] <rjharrison> Ahh Time Zones is it in UTC or BST
[15:29] <jonsowman> BST
[15:29] <rjharrison> That is always a bugger if it's not OBV
[15:30] <jonsowman> yeh I'm considering putting it all in UTC
[15:30] <rjharrison> I would be tempted to force it to UTC if it's not a big issue as it will be used globally
[15:30] <jonsowman> will do :)
[15:30] <juxta> jonsowman: not finding wind data for me at the moment, just stalling there. I've got to dash, will be back in 20 mins.
[15:30] <jonsowman> have made a github issue for it
[15:30] <jonsowman> juxta: ok, will try and sort it out when you're back
[15:30] <rjharrison> Unless you want sort out local time zones which is a pain in the arse
[15:31] <jonsowman> very true
[15:31] <jonsowman> github issue for UTC'ing made
[15:31] <rjharrison> Mightbe worht putting UTC on pannel interface too.
[15:32] <jonsowman> yup
[15:32] <rjharrison> It looks really good though
[15:33] <jonsowman> thanks
[15:33] <rjharrison> I wouldn't bother about cashing gribs unless you start to get millions of hits
[15:33] <jonsowman> hopefully a bit nicer to use than the old one
[15:33] <rjharrison> well hundreds
[15:33] <jonsowman> the main thing to do is to get it look through hourly predictor gribs before downloading fresh
[15:33] <jonsowman> since the hourly pred gets them every 6 hours and theyre fresh
[15:33] <rjharrison> It's really helpfull to know that your data is based on the latest available information
[15:34] <jonsowman> that is true
[15:34] <jonsowman> if it were to use data from the hourly predictor it would need to check first that no fresh data is available
[15:34] <rjharrison> If you do go down the cache route make sure that you put how old the grib data is
[15:34] <jonsowman> yes it should definitely display the GRIB model timestamp that it's using
[15:35] <rjharrison> Yep but the get data died one time and I think the GRIB data was a week old at one point
[15:35] <jonsowman> yeh
[15:35] <jonsowman> must make sure that doesn't happy
[15:35] <jonsowman> *happen
[15:35] <jonsowman> downloading the data fresh every time is not the end of the world
[15:35] <rjharrison> I'm sure there is a way to check the age of the GRIB data
[15:35] <jonsowman> can wait 30-60 seconds for a prediction
[15:36] <rjharrison> Yep it's not doing the same thing as the hourly
[15:36] <jonsowman> exactly
[15:36] <jonsowman> if you set the software to GFS HD
[15:36] <jonsowman> and the deltas to 10
[15:36] <jonsowman> it takes about 3-4 minutes
[15:36] <jonsowman> but that's the longest it ever gets
[15:37] <rjharrison> Which is fine and proably what you intended if you set those parameters
[15:37] <jonsowman> yup
[15:37] <jonsowman> absolutely
[15:37] <rjharrison> Typicaly most are going to be happy with 3 and I think that should be the default. Which indeed I think it is
[15:38] <jonsowman> yes it is

[15:38] <jonsowman> HD instead of non-HD gives you a slightly more accurate prediction

[16:14] <juxta> jonsowman: back now :)
[16:14] <jonsowman> juxta: hey
[16:15] <jonsowman> where was it you were trying as a launch location
[16:15] <juxta> let me just try to reproduce it
[16:15] <jonsowman> ok
[16:16] <juxta> jonsowman: ok, so I first did a prediction from Adelaide with default params
[16:16] <jonsowman> right
[16:17] <juxta> then a prediction from -35.1217, 138.8503 with the same params
[16:17] <juxta> that's where it seems to get stuck at 0% downloading files
[16:17] <jonsowman> weird
[16:18] <jonsowman> i just did it - works fine
[16:18] <jonsowman> http://www.hexoc.com/hab/predict/predict/#!/uuid=83b144246e22ce32dc17e325c9961c9aaf213a25
[16:18] <juxta> hm
[16:18] <juxta> my uuid was: a082754c558067ac2781dcd06bfc75697af0ee77
[16:18] <jonsowman> the progress json on the server indicates that it ran fine
[16:19] <juxta> hmm ok, so client side issue I guess
[16:19] <juxta> oh wait - I changed tabs again and now it's there
[16:20] <jonsowman> juxta: try again now
[16:20] <jonsowman> just deleted all gfs cache
[16:20] <juxta> hmm - progress bar still doesnt seem to be moving
[16:20] <juxta> lets see if it gives the prediction though
[16:21] <juxta> hrm - still sticking at 0%
[16:21] <jonsowman> strange
[16:22] <jonsowman> i'm trying again
[16:22] <juxta> I get 2 entries in the debug saying 'Server says: downloaded 0% of GFS files'
[16:22] <jonsowman> it should keep saying "Server says: <msg>" every 2 secs
[16:23] <juxta> just the 2 entries the last few times i've done it
[16:23] <jonsowman> hmm ok
[16:23] <juxta> i'll try again
[16:23] <jonsowman> is the 2nd launch location the one you want saved?
[16:23] <juxta> yeah - call it 'Wistow'
[16:24] <jonsowman> will do
[16:25] <jonsowman> done :)
[16:26] <juxta> excellent :)
[16:26] <juxta> hmm - trying again, this time stuck at 'Searching for wind data...'
[16:26] <jonsowman> just ran the two successively and worked fine
[16:26] <juxta> perhaps its my browser
[16:26] <jonsowman> what browser?
[16:27] <jonsowman> this predictor is known to screw up in chrome at the moment
[16:27] <jonsowman> again on the todo list
[16:27] <juxta> FF 3.5.9
[16:27] <jonsowman> hmm
[16:27] <jonsowman> should be fine
[16:27] <juxta> i'll try ff 3.6.3
[16:28] <jonsowman> if you open the debug window during a prediction
[16:28] <jonsowman> you should see "downloaded x% of gfs files"
[16:28] <jonsowman> every 2 secs
[16:28] <jonsowman> until the prediction is finished
[16:29] <juxta> yeah I have the debug window open - when the bar stalls at 0% I see 2 entries for 'downloaded 0%...', then nothing further, when the proress bar stalls at 'searcing for wind data', the last thing I see is 'something or other JSON' ;p
[16:29] <juxta> let me try again, forget the exact message
[16:31] <juxta> ok jonsowman, what happens is I get 2 entries for 'downloaded 0% of gfs files', which come 2 seconds apart, then it stops
[16:31] <juxta> uuid that time was 1cab5e8ff1e69156ba9c18c3da7f5559def74a82
[16:32] <jonsowman> again progress.json on the server says the prediction finished fine
[16:32] <juxta> hrm
[16:32] <jonsowman> http://www.hexoc.com/hab/predict/predict/#!/uuid=1cab5e8ff1e69156ba9c18c3da7f5559def74a82
[16:32] <jonsowman> its something to do with your browser killing the javascript that polls for progress
[16:32] <juxta> about to restart with updated FF, 1 second
[16:32] <jonsowman> ok
[16:33] <juxta> working this time I think :)
[16:33] <jonsowman> fingers crossed...
[16:34] <juxta> hmm, actually - got stuck at 40%
[16:34] <juxta> got 2 messages for 40%, then the log stopped
[16:34] <jonsowman> :\
[16:35] <jonsowman> cannot reproduce that error
[16:35] <jonsowman> can you install Firebug
[16:35] <jonsowman> and watch the XHR requests?
[16:35] <juxta> sur
[16:35] <juxta> sure*
[16:37] <juxta> jonsowman: ok, firebug's installed - how do I view the XHR requests?
[16:39] <jonsowman> open firebug with the little icon in bottom right
[16:39] <jonsowman> click the Net tab
[16:39] <jonsowman> and use the arrow to set Enabled
[16:39] <juxta> ah, got it
[16:39] <jonsowman> then run a prediction and watch the XHR tab
[16:39] <juxta> must be my theme or something - the net tab was barely visible until I enebaled it
[16:39] <juxta> enabled*
[16:39] <jonsowman> odd
[16:40] <juxta> I didn't realise it was there :)
[16:40] <jonsowman> on pageload there should be an XHR for sites.json
[16:40] <juxta> yep
[16:40] <juxta> also get that when I change the location
[16:40] <jonsowman> then when you run a prediction, you should get XHRs for progress.json every few seconds
[16:41] <jonsowman> yes, that's right
[16:41] <jonsowman> when prediction completes, there will be one for ajax.php with a parameter of getCSV
[16:41] <juxta> ok - I'm getting the requests showing up, but the requests are being aborted
[16:41] <juxta> it looks like it's trying ever 2 secs though
[16:42] <jonsowman> what file is it looking for?
[16:42] <jonsowman> ie. any info as to why aborted
[16:42] <juxta> http://www.hexoc.com/hab/predict/predict/preds/16dacfed0f881a2c75a091dd214d043f6572f985/progress.json
[16:42] <juxta> doesnt seem to have a status code
[16:42] <juxta> oh wait
[16:42] <jonsowman> well that file exists so should work
[16:42] <juxta> I think I see what it is
[16:42] <jonsowman> go on
[16:42] <juxta> it gets 200 OK for a few goes
[16:43] <juxta> then the server returns 304 not modified, from that point on the requests are aborted
[16:43] <jonsowman> i've told the webserver not to cache jsons
[16:43] <jonsowman> so it should only get 304 if the file really is not mofidfied
[16:44] <juxta> hmm
[16:44] <juxta> same happens if I run a prediction in the UK btw
[16:44] <juxta> when I was around half an hour ago I was on another machine, also FF on windows though
[16:45] <jonsowman> http://lister.hexoc.com/1.png
[16:45] <jonsowman> that's what it looks like for me
[16:46] <juxta> hmm
[16:46] <juxta> let me screenshot
[16:46] <jonsowman> thanks :)
[16:48] <juxta> jonsowman: www.bogaurd.net/xhr.png
[16:50] <jonsowman> how weird
[16:50] <jonsowman> they're all timing out
[16:51] <jonsowman> hang on a tick
[16:51] <juxta> timeout is 500ms?
[16:51] <jonsowman> yup
[16:51] <juxta> I'm a fair bit further away from your server than you are I'm guessing
[16:51] <juxta> 500ms doesn't sound *that* unreasonable
[16:51] <jonsowman> try again now :)
[16:52] <juxta> like clockwork :)
[16:52] <jonsowman> :)
[16:52] <jonsowman> good good
[16:52] <jonsowman> so its just a ping thing
[16:52] <juxta> seems it's about 600ms when it has been modified
[16:52] <jonsowman> 500ms is a bit too tight for aus to UK
[16:52] <jonsowman> does it ever go above 1000ms?
[16:53] <juxta> nah
[16:53] <jonsowman> its at 1500 at the moment, but would prefer 1000 if that's going to work
[16:53] <jonsowman> ok, thanks
[16:53] <jonsowman> all working okay now then?
[16:53] <juxta> yep, seems perfect :)
[16:53] <jonsowman> lovely
[16:53] <jonsowman> thanks a lot for that juxta
[16:53] <jonsowman> most helpful :)
[16:53] <juxta> no worries, could have been tricky to find, hehe
[16:54] <jonsowman> very
[16:54] <juxta> jonsowman: maybe you can tell the JS that if the last 2 or 3 queries time out it should step up the delay and timeout values?
[16:55] <juxta> I'm pretty sure that if I do this on my mobile broadband, it'll timeout with 1000ms
[16:55] <jonsowman> yeh that's a good idea
[16:55] <juxta> esp if I'm driving in the car at 100km/h
[16:55] <jonsowman> will implement that :)
[16:55] <jonsowman> thanks
[16:55] <juxta> no worries

[16:56] <jonsowman> github issue made for it
[16:56] <juxta> now to play with some landing predictions :)
[16:56] <jonsowman> will get round to it asap
[16:56] <jonsowman> :)
[16:56] <juxta> how does the predictor handle multiple threads - does it allow multiple predictions to run at the same time?
[16:57] <jonsowman> yup as many as you like
[16:57] <juxta> oh nice
[16:57] <juxta> a step up from the old predictor then ;)
[16:57] <jonsowman> if two are running for exactly the same parameters, it'll kill the second, and the ajax will pick up on the progress of the first
[16:57] <jonsowman> the UUID thing is a SHA1 hash of the launch parameters :)
[16:58] <juxta> hehe, clever
[16:59] <juxta> jonsowman: have a look at -34.9835, 140.4506
[16:59] <juxta> at the moment the winds will blow me around there
[17:00] <juxta> no roads in there for about 20-30km
[17:00] <jonsowman> haha nice
[17:00] <juxta> btw - is the time GMT?
[17:01] <jonsowman> when you run a prediction it changes the url in the address bar - you can give that url to someone and it'll bring up your prediction
[17:01] <jonsowman> juxta: BST
[17:01] <juxta> oh yep - didn't notice
[17:01] <juxta> BST = Summer time?
[17:01] <jonsowman> yes
[17:01] <jonsowman> GMT +1 at the mo
[17:01] <juxta> GMT +1?
[17:01] <jonsowman> yup
[17:01] <juxta> haha
[17:01] <jonsowman> planning to convert the whole thing to UTC
[17:01] <jonsowman> at rjharrison suggested
[17:01] <juxta> even more adjusting for me
[17:01] <jonsowman> s/at/as
[17:02] <jonsowman> yeh, sorry
[17:02] <juxta> i'll forgive you :)
[17:02] <juxta> weather predictions for me at the moment are rubbish
[17:02] <jonsowman> :(
[17:02] <jonsowman> you planning to launch soon?
[17:02] <juxta> I'm going to have a massive drive if I launch soon
[17:03] <juxta> yeah, hoping to
[17:04] <jonsowman> hopefully the weather will get better soon then
[17:04] <juxta> I think it must be a winter thing
[17:05] <jonsowman> yea
[17:05] <juxta> we tend to get pretty strong winds off the sea - I live on the seafront, the other night it was unbelievable
[17:06] <juxta> strong enough to bring down power lines certainly, too strong to launch a balloon in :)
[17:06] <jonsowman> blimey
[17:06] <jonsowman> yeh probably not a good idea to launch in that
[17:07] <juxta> what's the difference between GFS and GFS HD?
[17:07] <jonsowman> GFS has 23 levels of wind data through the atmosphere
[17:07] <jonsowman> HD has 41
[17:07] <juxta> oh right
[17:07] <jonsowman> so slightly better and more accurate predictions with HD
[17:07] <jonsowman> at the expense of taking longer
[17:07] <juxta> slower though?
[17:07] <jonsowman> indeed
[17:07] <juxta> alrighty
[17:07] <juxta> oh wow, predictions for the 18th look acceptable
[17:08] <juxta> http://www.hexoc.com/hab/predict/predict/#!/uuid=e91a1e719d42d25add1def1b3a0a36cadddd845d
[17:08] <jonsowman> hey that looks better
[17:08] <jonsowman> :)
[17:08] <juxta> only complicated by the river
[17:08] <juxta> given that there are only 2 crossings
[17:08] <jonsowman> ah
[17:08] <jonsowman> i see
[17:08] <juxta> you've got to be sure of which side it's going to come down on
[17:08] <jonsowman> haha yes
[17:09] <juxta> besides the ocean, do you guys have to avoid much?
[17:12] <jonsowman> airports, london and the sea
[17:12] <jonsowman> pretty much what it amounts to
[17:12] <juxta> not so bad
[17:12] <jonsowman> yeh could be worse
[17:12] <juxta> big chunk of military airspace here
[17:12] <jonsowman> with landing predictors avoiding the above is reasonably simple
[17:12] <juxta> pays to avoid that
[17:12] <jonsowman> hah yes
[17:17] <juxta> hm, tab behaviour has changed in this new version of firefox
[17:17] Jasperw (~jasperw@93.89.81.29) joined #highaltitude.
[17:17] <jonsowman> juxta: yes it has - I prefer it now though
[17:18] <juxta> bah, I liked it better before
[17:18] <jonsowman> haha - sorry; made you upgrade
[17:18] <juxta> that when I opened a bunch of tabs from an article they were in order, rather than reverse order :)
[17:18] <jonsowman> yeh fair enough
[17:18] <Randomskk> I think it's customisable
[17:20] <juxta> yeah, about:config
[17:20] <juxta> browser.tabs.insertRelatedAfterCurrent - fixed :)
[17:22] <juxta> jonsowman: how much GFS data is available? 5 days?
[17:22] <Randomskk> 7
[17:23] <Randomskk> but I wouldn't trust it much beyond 4
[17:23] <juxta> hm - I tried the 21st, and it's got stuck on 0% of loading wind data
[17:23] <juxta> though the debug window is updating this time
[17:23] <Randomskk> just give it time
[17:23] <Randomskk> the server it gets them from can be slooow
[17:23] <jonsowman> Randomskk: that issue appears to have fixed itself
[17:23] <jonsowman> juxta: might be a little bit too far ahead
[17:24] <jonsowman> try for 20th and see if that works
[17:24] <juxta> 20th works
[17:24] <jonsowman> 21st wont - need to get server to check that before trying to start a prediction
[17:24] <juxta> I gave it about 2 minutes, guess the 21st was too far away
[17:24] <jonsowman> if you tried like 26th for example it would fail
[17:24] <jonsowman> the margin is a little out

[17:28] <DanielRichman> jonsowman, that's strange.
[17:28] <DanielRichman> jonsowman, also... the box in question isn't draggable by a certain area
[17:28] <juxta> jonsowman: just realise the launch card can be dragged around
[17:28] <juxta> but only by some parts
[17:28] <DanielRichman> yeah centre right parts are undraggable
[17:28] <jonsowman> Yes I plan to put in drag handles for all the boxes
[17:28] <DanielRichman> no
[17:29] <DanielRichman> it's the left and right margins I can't drag it by
[17:29] <Randomskk> box still needs borders on two sides too
[17:29] <juxta> I'd be happy with it being fixed, but that's me :)
[17:29] <DanielRichman> I can drag it by the middle, and the top and bottom margins
[17:29] <jonsowman> Randomskk: borders sorted
[17:29] <SpeedEvil> lat/lon deltas si how much data is loaded?
[17:30] <jonsowman> SpeedEvil: yes
[17:30] <SpeedEvil> Ah - I was thinking montecarlo
[17:30] <Randomskk> montecarlo predictor isn't done yet sadly
[17:30] <juxta> montecarlo predictor?
[17:30] <SpeedEvil> I'm not complaing - above is very shiny
[17:31] <Randomskk> rjw's pet project, it would give confidence levels to predicted landing areas
[17:31] <SpeedEvil> I jsut assumed 3*3 referred to a 3*3 box of starting predictions (which seemed large)
[17:31] <Randomskk> as I understand it essentially involves running many parallel predictions given small variations in wind velocity at each point and using them to come up with a confidence ring
[17:31] <juxta> Randomskk: nifty :)
[17:31] <Randomskk> so "80% sure it'l be in this circle, 50% in this smaller circle, 10% on this spot" kind of deal
[17:32] <juxta> yeah
[17:32] <Randomskk> instead of the current thing which just assumes no errors in wind data and gives you where it lands
[17:32] <Randomskk> I may be totally wrong, that's my rough understanding of the process
[17:32] <Randomskk> apparently it kind of works and he's using CUDA and other stuff but nothing implementable on a web interface yet
[17:32] <SpeedEvil> Randomskk: I was assuming fiddling with the launch a bit. So you move the launch point in a 1km circle.
[17:32] <juxta> jonsowman: is there a link somewhere to download a KMZ/KML of the flight path?
[17:32] <Randomskk> could also be it
[17:32] <SpeedEvil> If the output is a 1.5km circle, you're probably good.
[17:32] <juxta> (or a plan for one?)
[17:32] <Randomskk> not yet unfortunately, but it's on the list
[17:32] <jonsowman> juxta: it's on the todo list :)
[17:32] <SpeedEvil> If it's a 1500km circle, not so much :)
[17:32] <Randomskk> will be done by the time this becomes the main predictor
[17:32] <jonsowman> juxta: http://github.com/jonsowman/cusf-standalone-predictor/issues
[17:33] <juxta> oh nice :)
[17:35] <juxta> jonsowman: does this do the hourly predictions too?
[17:36] <jonsowman> the hourly predictor is a seperate system
[17:36] <jonsowman> the actual predictor itself is the same though
[17:41] <juxta> alrighty
[17:41] <juxta> I best be off to bed
[17:41] <jonsowman> see you
[17:41] <juxta> 2am here - night all :)
[17:41] <jonsowman> cheers for your help
[17:41] <juxta> no worries :)

[18:26] <SpeedEvil> Oooh - cool too.
[18:28] <fsphil> Earth 1 - Satellite 0
[18:28] <fsphil> it was returning a sample of an asteroid, hopefully that part survived
[18:29] <SpeedEvil> It looked like it was fine, but that was the main part of the craft that burned up - leaving the payload + heatshield on a lower+faster trajectory
[18:30] <fsphil> yea I think that's the dot travelling alongside it
[18:31] <fsphil> it must be difficult seeing all your hard work burning up like that, even though it was intentional

[20:48] Action: jcoxon needs to get Peg VII ready for a potential launch on wednesday
[20:54] <fsphil> what kind of time are you hoping to launch? I'll be at work but I might try receiving some of the sstv remotely
[20:54] <jcoxon> i assume it'll be in the morning
[20:54] <jcoxon> eek sstv at range
[20:55] <fsphil> aye lol
[20:55] <fsphil> I don't hold much hope
[20:56] <fsphil> rtty was pushing it
[20:56] <jcoxon> fsphil, could use an online radio
[20:57] <fsphil> nah - I'm sure they'll be posted online more or less in real time?
[20:58] <jcoxon> yeah
[20:58] <jcoxon> need to speak to the cusf gang

[21:56] <SpeedEvil> Consider if you want to make it a proper room.
[21:56] <SpeedEvil> In principle you may need building regs approval.
[21:56] <SpeedEvil> In practice, you may want to think about what would be required to make it a proper room - legally - so you could sell it as such.
[21:57] N900evil (~Speedevil@tor/regular/SpeedEvil) left irc: Ping timeout: 258 seconds
[21:57] <SpeedEvil> So - for example - construct the floor as appropriate to the regs - rather than having to rip it up and redo, if you decide to do that
[22:05] N900evil (~Speedevil@tor/regular/SpeedEvil) joined #highaltitude.
[22:07] <fsphil> yea it would have to be done legit
[22:08] <fsphil> it wouldn't be a big area, and I wouldn't be removing any of the beams
[22:08] <fsphil> just work around them
[22:08] DaveyC (~IceChat7@cpc3-live6-0-0-cust498.know.cable.virginmedia.com) joined #highaltitude.
[22:08] <SpeedEvil> 'legit' - as in to make it a habitable space is perhaps considerably more complex than that.
[22:08] <SpeedEvil> something to think about anyway
[22:09] <SpeedEvil> less important if you can't envision movin gin the next decade
[22:09] <fsphil> yep -- I really need someone who knows what they're talking about to go up and have a look
[22:09] <fsphil> a few houses have converted their attics into rooms around here but it wasn't a small job
[22:09] <SpeedEvil> there are actually some not bad websites out there on the basics.

[22:21] <jcoxon> fsphil, so for hadie you had the jpeg camera just exposed
[22:21] <jcoxon> ?
[22:21] <jcoxon> did you rotate the lens at all?
[22:21] <fsphil> yea it was looking out through a hole in the insulation
[22:22] <fsphil> the lens was as I got it -- focus seemed fine
[22:22] <fsphil> the only problem I had was the camera occasionally not responding
[22:23] <jcoxon> was that just on the desk? or in flight?
[22:23] <fsphil> both
[22:23] <jcoxon> okay, i haven't had that at all
[22:24] <fsphil> I'm probably not initialising it properly
[22:26] <jcoxon> i've got it pretty solid now,
[22:27] <jcoxon> 1 picture, 6 strings of rtty
[22:28] <fsphil> how well does mmsstv handle frequency drift?
[22:28] <jcoxon> mid picture not badly at all
[22:29] <jcoxon> but you need to line it up at the beginning
[22:29] <jcoxon> going to insulate well to try and reduce drift
[22:33] <fsphil> it's the one advantage the jpeg over rtty has, drift isn't a big problem
[22:34] <jcoxon> :-)

[22:35] <fsphil> I've noticed the huffman and quantisation tables the camera uses are the same for every image. I'm going to try and code it so that they're not transmitted every time
[22:36] <fsphil> should go some way to solving the 'first packet lost kills the entire image' problem
