[10:59] <fsphil> man my internet has gotten really unreliable since I got the FTTH installed
[11:06] <Randomskk> huh, that's odd
[11:06] <Randomskk> you'd think ftth would be awesome
[11:06] <fsphil> oh it's really fast, just keeps dropping the connection at least twice a day
[11:06] <fsphil> for about 5 minutes
[11:06] <Randomskk> :/
[11:06] <Randomskk> have you contacted them about it?
[11:06] <fsphil> yea, not heard back yet
[11:07] <Randomskk> fibre really should be both reliable and awesome
[11:07] <fsphil> yea - I downloaded a 700mb iso image in a few minutes - that was neat

[13:17] <eroomde> smea: again, I love you dearly and everything, but I will kick you from the channel in favour of having it clogged up with your connection issues
[13:17] <eroomde> its nothing personal, just netiquette
[13:18] <MoALTz> you can set most clients to ignore parts and joins you know...
[13:19] <eroomde> it's useful information for the most part
[13:19] <eroomde> especially if you don't have a separate list of users, such as with irssi
[13:20] <eroomde> A lot of higher volume channels I've been on have bots that kick automatically as a function of connects/disconnects in a unit of time or per contribution
[13:21] smea (~smealum@85-171-205-215.rev.numericable.fr) left irc: Ping timeout: 276 seconds
[13:22] <LazyLeopard> Aye, those sorts of connection issues do get tedious, especially when they're associated with a user who'c AFK.
[13:23] <MoALTz> use /names to see a list of users in irssi
[13:23] <Randomskk> or just /n
[13:23] <Randomskk> but either way that is boring
[13:23] <Randomskk> you can even get user lists, but it doesn't change the problem of people with loads of join/quit spam
[13:26] smea (~smealum@85-171-205-215.rev.numericable.fr) joined #highaltitude.
[13:27] <eroomde> smea: ping
[13:27] <LazyLeopard> fsphil: The BAA has put out a call for reports on that fireball you saw.
[13:27] <eroomde> MoALTz: the nature of HAB conversation, with discrete launches that involve organising teams of people, is that you want to have an interrupt to know when someone comes online
[13:28] <LazyLeopard> (where BAA = British Astronomical Association ;)
[13:28] <fsphil> LazyLeopard, ooh must contact them about that
[13:28] <eroomde> I want to know where jcoxon or RocketBoy come online as I often co-ordinate launches with them. having to poll is a worse solution
[13:28] <Randomskk> you could also just ignore smea
[13:28] <fsphil> afaik nobody else here saw it
[13:28] <LazyLeopard> Do you have contact details?
[13:28] <fsphil> not yet
[13:29] <eroomde> combined with the fact that smea hasn't made any contributions, as far as i remember, in the five years i've been on this channel, means I feel justified in doing this
[13:29] <LazyLeopard> I could forward you the e-bulletin...
[13:30] <fsphil> ooh yep, want my email addy?
[13:30] <LazyLeopard> In PM is good, yeah

[13:32] <Randomskk> of the 1400 mentions of smea in my logs, approximately 1370 are joins or quits, the rest are renames or other people talking about him

[13:35] <jonsowman> /ignore #highaltitude smea JOINS PARTS QUITS
[13:35] <jonsowman> I think

[13:35] <jonsowman> oh wait
[13:35] <jonsowman> don't do that
[13:35] <fsphil> googling for ~smealum@85-171-205-215.rev.numericable.fr shows him in a few other channel logs too
[13:35] <Randomskk> or just /ignore smea given as they've never said anything
[13:35] <jonsowman> yea
[13:35] <Randomskk> or just /mode #highaltitude +b smealum@*
[13:35] <eroomde> Randomskk: that's a sharp knife though
[13:35] <eroomde> they might say something someday
[13:36] <jonsowman> it's definitely possible to have irssi ignore joins/parts/quits from a certain user on a certain channel
[13:36] <jonsowman> I'm trying to make sense of /help ignore
[13:39] smea (~smealum@85-171-205-215.rev.numericable.fr) left irc: Ping timeout: 240 seconds

[13:39] <jonsowman> yea
[13:39] <jonsowman> I just got to that :)
[13:39] <Randomskk> okay, I will not do that yet, and let you know when he joins ;o
[13:40] <jonsowman> righto
[13:43] <jonsowman> /ignore -channels #highaltitude smea JOINS PARTS QUITS
[13:43] <jonsowman> if you wanted to limit it to #highaltitude
[13:43] <jonsowman> not that it really matters in this case
[13:43] <Randomskk> indeed

[13:44] <Randomskk> he's just joined
[13:45] <Randomskk> did you see anything? :o
[13:45] <jonsowman> nope
[13:45] <Randomskk> sweet
[13:45] <jonsowman> silence is golden
[13:45] <Randomskk> will let you know when he quits then ignore myself
[13:45] <Randomskk> well not actually "ignore myself" so much as "ignore him myself"
[13:45] <jonsowman> using the #highaltitude limited one, but either will be fine ofc
[13:45] <jonsowman> haha
[13:45] <jonsowman> ignoring yourself would be silly :P
[13:46] <Randomskk> wonder if I can
[13:46] Action: Randomskk tries
[13:46] <Randomskk> okay ignoring myself
[13:46] <Randomskk> ...
[13:46] <Randomskk> nope, I can still see myself
[13:46] <jonsowman> :(
[13:46] <jonsowman> that's sad
[13:46] <Randomskk> bizarre
[13:46] <Randomskk> and it still shows up in logs
[13:46] <Randomskk> there we go
[13:46] <jonsowman> so is ignoring yourself
[13:46] <jonsowman> heh
[13:46] <Randomskk> well true

[13:49] <eroomde> i have set that up to

[13:49] <eroomde> no we wait and see if it works for me
[13:52] <Randomskk> well I have also now ignored him

[18:59] <Laurenceb_> its a semi work project
[18:59] <Randomskk> cool
[18:59] <Laurenceb_> im doing it with opensource tools to see if its possible
[19:00] <Laurenceb_> -person films graphic lcds on phonecam and data is extracted
[19:00] <Laurenceb_> which is pretty horrible as the screen is shaking all over the place
[19:01] <Laurenceb_> but the code could have some neat uses on uavs for example
[19:01] <Laurenceb_> if you were flying over building you could do attitude computation from the perspective transform matrices
[19:01] <Laurenceb_> - building are squarish
[19:02] <SpeedEvil> Awesome.
[19:02] <Laurenceb_> if you want to trade lots of mems for stupid cpu horsepower
[19:02] <SpeedEvil> Is it a time graph?
[19:02] <SpeedEvil> I mean - you can correlate it over time to check.
[19:03] <Laurenceb_> yes, thats what im doing
[19:04] <Laurenceb_> useful for 3D scene capture as well - dasically it takes a edge detector output and fits and links a load of straight lines
[19:04] <Laurenceb_> so you have a ton of polygons spat out
[19:05] <Laurenceb_> possible to turn that into a wireframe with texels
[19:05] <Laurenceb_> or texture maps .. whatever they are called

[21:34] <Dan-K2VOL> You guys looking to fly saturday?
[21:35] <fsphil> I'm hoping to
[21:35] <fsphil> if the predicted landing spot stays on dry land
[21:35] <Randomskk> hm
[21:35] <Randomskk> wonder if I'll be able to pick it up
[21:35] <Randomskk> could do with being higher up but might give you a shot
[21:36] <fsphil> how far are you?
[21:36] <Dan-K2VOL> We are too, will spacenear.us support multiple flights and dozens of listeners?
[21:36] <Randomskk> weybridge
[21:36] <Randomskk> south and west of london
[21:36] <Dan-K2VOL> it isn't our main telemetry link, just auxilliary
[21:36] <Randomskk> but very close to london
[21:36] <Randomskk> Dan-K2VOL: yes
[21:36] <Randomskk> it supports multiple simultaneous flights, though the user interface isn't as much fun then
[21:37] <Randomskk> still it works
[21:37] <Dan-K2VOL> great Randomskk
[21:37] <Dan-K2VOL> that's cool
[21:37] <Randomskk> is this another 300 baud continuous data flight? :P
[21:37] <fsphil> Randomskk, it might be possible with a decent yagi -- though it's 300 baud so might not carry as far as a 50 baud signal
[21:37] <Randomskk> you broke it from having so much data last time
[21:37] <Dan-K2VOL> haha oops
[21:37] <Randomskk> well
[21:37] <Randomskk> the tracker didn't break
[21:37] <Randomskk> but firefox could no longer decode the incoming ajax
[21:37] <Randomskk> so died horribly
[21:38] <Randomskk> by horribly I mean "downloaded data at full speed for as long as you had the window open with no sign it was doing anything"
[21:38] <Dan-K2VOL> HF should be hourly through cruise, but every 15 seconds on ascent
[21:38] <Randomskk> one of the things the new system will hopefully improve on
[21:38] <fsphil> Dan-K2VOL, I'll be launching between 10:00 and 11:00 UTC
[21:38] <Dan-K2VOL> oh nice, us too
[21:38] <fsphil> sweet, two balloons in the air at the same time
[21:38] <fsphil> wasn't tim talking about launching saturday too?
[21:39] <Randomskk> hehe
[21:39] <fsphil> I've 300 baud continuous, but most of that will be image data -- until descent anyway, then it's all telemetry
[21:39] <Dan-K2VOL> James is organizing listeners for this HF one
[21:39] <fsphil> aah yes he mentioned that
[21:39] <fsphil> drat I was hoping to listen to that!
[21:40] <Dan-K2VOL> Bill Brown WB8ELK built the TX, we're doing the rest of the payload
[21:40] <Dan-K2VOL> we'll be in the air from 1100 UTC + 16 hours
[21:40] <Randomskk> nice long flight
[21:40] <fsphil> oh that's loads of time
[21:40] <fsphil> I'll be out of the sky within an hour and a half probably
[21:40] <russss> I might try and give that a listen
[21:41] <russss> although my HF antenna was a bit temperamental last time I tried it.
[21:41] <fsphil> Dan-K2VOL, 300 baud on hf?
[21:41] <Dan-K2VOL> it's 40m

[21:41] <Dan-K2VOL> let me check, Bill and james are really taking care of HF entirely, we're overwhelmed trying to use the satellite network
[21:42] <Dan-K2VOL> Domino, and RTTY 110 baud
[21:42] <fsphil> ah, domino might manage the distance
[21:43] <Dan-K2VOL> 2W
[21:44] <fsphil> does polarisation survive propagation? my hf antenna is horizontal, I'm guessing the balloon is vertical
[21:44] <Randomskk> propagation usually messes the polarisation iirc
[21:44] <Randomskk> such that it comes in at many polarisations
[21:44] <Randomskk> this is entirely my hazy recollections of the full license exam though
[21:45] <fsphil> makes sense.. I think
[21:45] <fsphil> it's a long flight so I might be able to try both
[21:45] <fsphil> do a comparison
[21:45] <fsphil> assuming I receive anything that is
[21:46] <fsphil> i haven't been receiving much on 40m lately
[21:46] <fsphil> except during the daytime
[21:50] <fsphil> oh sorry, it' 20m that I haven't been getting much on

[22:47] <Dan-K2VOL> satellite modem mostly, we weren't going to fly HF due to the very heavy workload of managing to keep volunteers online
[22:47] <eroomde> see if we can deploy a vertical something
[22:47] <Dan-K2VOL> haha
[22:47] <jcoxon_> eroomde, ooo will you test the latest dl-fldigi for me
[22:47] <Dan-K2VOL> np jcoxon
[22:47] <eroomde> jcoxon_: yes
[22:47] <jcoxon_> eroomde, balloon vertical...
[22:47] <eroomde> link me up
[22:48] <jcoxon_> https://github.com/downloads/jamescoxon/dl-fldigi/dl-fldigi-3.20.29.r114.dmg
[22:48] <eroomde> jcoxon_: it doesn't matter if it's not LOS
[22:48] <eroomde> the onospheric bouncing scatters the polarisation
[22:48] <eroomde> but we could try and balloon tethered vertical
[22:48] <jcoxon_> thats what i mean
[22:49] <eroomde> oh i seeeeee
[22:49] <fsphil> hmm.. I've a spare balloon
[22:49] <fsphil> and might have some left-over gas
[22:50] <eroomde> bazzooka dipole?
[22:50] <Dan-K2VOL> the web link I gave you will only show satellite modem relayed data for this flight
[22:50] <eroomde> Dan-K2VOL: what's the HF freq?
[22:50] <Dan-K2VOL> so it will be delayed by anywhere from 15 to 30 minutes
[22:51] <jcoxon_> eroomde, to tell the truth i'm not sure if i'll be down in worthing next weekend
[22:52] <eroomde> not to worry. I'll probably still have a go if I'm down
[22:52] <fsphil> be a waste of a good 1kg balloon though
[22:53] <jcoxon_> eroomde, sucess with dl-fldigi?
[22:53] <eroomde> i might try the typical SOTA rig
[22:53] <Dan-K2VOL> eeroomde, unknown, 40m though. Check here for an update when we know it http://wiki.whitestarballoon.com/doku.php?id=hardware:radio:wb8elkwhitestarn17 Jcoxon and Bill Brown WB8ELK will be the pointmen on the HF operations in flight
[22:53] <eroomde> oh sorry i forgot it was downloading
[22:54] <eroomde> thanks Dan-K2VOL
[22:54] <jcoxon_> okay now need a tester for the windows dl-fldigi please
[22:54] <eroomde> jcoxon_: remind me which of dl-fligi and dl-fldigiHAB I want to be using?
[22:54] <fsphil> those testing dl-fldigi, could you also test decoding an image perty please: http://www.sanslogic.co.uk/ssdv/capture-20101004.flac
[22:54] <jcoxon_> okay dl-fldigiHAB opens up the nice version
[22:55] <jcoxon_> dl-fldigi opens the normal interface
[22:55] <fsphil> (300 baud, 1.5 stop bits, 350hz shift, 8-bit)
[22:56] <eroomde> seems to work fine for me jcoxon_
[22:56] <eroomde> want me to run a sample wav?
[22:56] <jcoxon_> windows volunteer please...
[22:57] <Dan-K2VOL> what do you need to have done jcoxon_
[22:58] <Dan-K2VOL> just fsphil's image?
[22:59] <jcoxon_> does this : https://github.com/downloads/jamescoxon/dl-fldigi/dl-fldigi-3.20.29.r114.exe
[22:59] <jcoxon_> download, install and run?
[22:59] <Dan-K2VOL> lets see
[22:59] <jcoxon_> fsphil, is just a bit of extra fun
[22:59] <fsphil> yay
[22:59] <jcoxon_> with his ssdv format of images over rtty
[23:00] <fsphil> what I'd like to test is multiple users uploading, see if my server puts the image together properly
[23:00] <fsphil> they should end up here: http://www.sanslogic.co.uk/ssdv/live.php
[23:01] <eroomde> fsphil: should the flac play in discrete little blocks of sound at about 1.5Hz?
[23:01] <eroomde> or is my vlc having a boobie?
[23:01] <fsphil> it should be continuous]
[23:02] slothearn (~euclid@pool-96-249-157-79.hrbgpa.fios.verizon.net) left irc: Quit: WoW timez
[23:03] <eroomde> i will try the vlc update
[23:05] <fsphil> fldigi might be able to read the flac directly
[23:06] <Dan-K2VOL> icannot
[23:06] <Dan-K2VOL> read the flac direct
[23:06] <eroomde> me neither
[23:06] <jcoxon_> fsphil, make it a wav file
[23:06] <Dan-K2VOL> vlc is stopping every 5 seconds here
[23:06] <fsphil> yea, one sec
[23:07] <Dan-K2VOL> oh great, freenode blocks mibbit chat now
[23:07] <eroomde> yep
[23:07] <Dan-K2VOL> that's wonderful, the only grandmother-friendly webchat
[23:07] <eroomde> annoying huh
[23:07] <Dan-K2VOL> yep, looks like we won't likely be on freenode
[23:08] <Randomskk> they have their own web irc I believe
[23:08] <Randomskk> though yea, it's not mibbit.
[23:08] <fsphil> yay ftth: http://www.sanslogic.co.uk/ssdv/capture-20101004.wav
[23:08] <Dan-K2VOL> which sucks balls compared to mibbit
[23:08] <jonsowman> webchat.freenode.net ?
[23:08] <jonsowman> true
[23:08] <jcoxon_> Dan-K2VOL, so dl-fldigi working then?
[23:09] <Dan-K2VOL> oh yes!, it's running and installed fine!
[23:09] <Dan-K2VOL> on Windows XP
[23:10] <eroomde> fsphil: what configuration of dl-fldigi for image decoding?
[23:10] DagoRed (~dago@j15-1.nat.iastate.edu) left irc: Remote host closed the connection
[23:10] <eroomde> wasn't aware it could do that
[23:10] <fsphil> 300 baud, 350hz shift, 8-bit, 1.5 stop bits, no parity
[23:10] DagoRed (~dago@j15-1.nat.iastate.edu) joined #highaltitude.
[23:10] <fsphil> click View->SSDV to open the image window
[23:10] <jcoxon_> Dan-K2VOL, great

[23:12] <jcoxon_> Dan-K2VOL, okay once wb8elk gets back to me on payload callsign i'll do a mass email of the lists recruiting listeners
[23:13] <jcoxon_> will also kick the various devs of the old system to invent away to have an up to date list of who is listening out
[23:13] <jcoxon_> that said this will do: http://maps.google.com/?q=http://www.robertharrison.org/listen/active_rx.php&t=p

[23:15] <iNatrium> cool
[23:15] <jcoxon_> will have HF and use spacenear.us

[23:15] <iNatrium> need to check out my HF antenna
[23:16] <iNatrium> should be named phoenix of knoxville :D
[23:16] <Zuph> jcoxon_: We might fall back into those ashes if we aren't too careful :-p
[23:16] <jcoxon_> nah
[23:18] <eroomde> fsphil: picture decoded
[23:18] <eroomde> VERY impressive
[23:18] GeekShadow (~Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[23:18] <fsphil> sweet
[23:18] <iNatrium> pics?
[23:18] <fsphil> was dl-fldigi in online mode?
[23:18] <iNatrium> did somebody say pics?
[23:18] <eroomde> thought it doesn't half take a while!
[23:18] <fsphil> yea 300 baud is a bit slow
[23:18] <fsphil> much better at 1200
[23:18] <fsphil> but that's a project for another time
[23:18] <eroomde> 4 times, at a guess?
[23:18] <fsphil> oddly yea!
[23:19] <eroomde> well you've got 3khz bandwidth aswell
[23:19] <fsphil> remove the stop and start bits and can squeeze a bit more off that time
[23:19] <fsphil> though it's no longer rtty then
[23:20] <eroomde> yes true
[23:21] <jcoxon_> ping sbasuita
[23:21] <jcoxon_> and i guess ping DanielRichman to ping sbasuita
[23:22] <jcoxon_> Dan-K2VOL, what #tag will we be using for the flight?
[23:22] <jcoxon_> for twitter?
[23:26] <jcoxon_> ooo packets
[23:27] <Randomskk> eroomde: do you know anything about couch being sloooow at some things that it doesn't seem like it should be?
[23:27] <fsphil> yay, receiving image!
[23:27] <eroomde> nope? but what sort of things?
[23:28] <Randomskk> so I have a load of documents containing a unix timestamp and a temperature
[23:28] <Randomskk> and I want to get five-minutely averages
[23:28] <eroomde> I know it periodically regenerates static views, which might take some time - but surely not at our scale?
[23:28] <Randomskk> my view has a map that outputs a key of the nearest five minute timestamp
[23:28] <Randomskk> which is fast, and the view is cached fine
[23:28] <Zuph> jcoxon_: #wssb1
[23:28] <jcoxon_> Zuph, thanks
[23:28] <Randomskk> and the reduce then takes the mean by outputting the total and count and current mean
[23:28] <Randomskk> if I run it without grouping, so I just get one row of result, it is super duper fast - cached properly
[23:28] <Randomskk> and if I run it without the reduce, it's also fast
[23:29] <Randomskk> but when I have reduce and grouping, so I get a result per five minute window, it's dog slow
[23:29] <Randomskk> despite theoretically being perfectly cachable and not being a 'bad' reduce
[23:29] <Randomskk> (it doesn't produce more data than input)
[23:29] <Randomskk> e.g. http://selwx.com/temperatures/_design/temperatures/_view/five_minute_averages?group=true&limit=2000
[23:29] <Randomskk> vs http://selwx.com/temperatures/_design/temperatures/_view/five_minute_averages?reduce=false&limit=2000
[23:30] <Randomskk> I'm only asking as I seem to remember you mentioning couch before :P
[23:30] <iNatrium> fsphil: are you launching on 18th too>
[23:30] <iNatrium> ?
[23:30] <fsphil> iNatrium, hope too yep
[23:30] <Randomskk> (this is a similar problem we're going to come up against when we have many telemetry documents and want to output a summary of them)
[23:31] <iNatrium> fsphil: sooo... with picture transmitting again?
[23:31] <fsphil> iNatrium, definitely :)
[23:31] <iNatrium> \o/
[23:31] <jcoxon_> eeek spacenear.us is going to get slammed
[23:31] <fsphil> lol
[23:31] <iNatrium> fsphil: you should submit pictures to spacenear.us
[23:32] <iNatrium> or if you twitter them, i can grab them from there
[23:33] <fsphil> dl-fldigi uploads the packets to http://www.sanslogic.co.uk/ssdv/data.php -- I can have that upload it to spacenear.us once they're complete

[23:35] <juxta> morning iNatrium
[23:35] <iNatrium> hi :D

[23:36] <Dan-K2VOL> just to give you guys a heads up, we'll be sending about 120 position reports in the first 30 minutes to spacenear.us
[23:36] <SpeedEvil> :)
[23:37] <iNatrium> that's nothing
[23:37] <jcoxon_> Dan-K2VOL, thats no issue, its when juxta does 10,000
[23:37] <Dan-K2VOL> oh nice
[23:37] <juxta> :D
[23:37] <iNatrium> juxta was sending one every second
[23:37] <iNatrium> only chrome could handle that
[23:37] <jcoxon_> + chase cars
[23:37] <Dan-K2VOL> lol holy crap, at what baud rate
[23:37] <jcoxon_> and multiple listening stations
[23:37] <iNatrium> multiple trackers add up
[23:37] <iNatrium> *listeners
[23:37] <juxta> it was more like 1 packet every 4-5 seconds, but we had lots of listeners
[23:38] <juxta> hey jcoxon_, your package turned up the other day, thanks a bunch for that :)
[23:38] <fsphil> does the tracker download every received string? even if it's a duplicate?
[23:38] <iNatrium> yes, it's used for the signal lines
[23:38] <fsphil> oh yes
[23:38] <iNatrium> and we stream the data so...
[23:38] <jcoxon_> juxta, no worries
[23:42] <juxta> are there any launches currently planned?
[23:42] <fsphil> iNatrium, has the image upload api changed since I last time it?
[23:42] <fsphil> time it = used it
[23:43] <fsphil> last spring
[23:49] <fsphil> hmm.. the way the prediction is changing this could land in scotland :)

[23:50] <fsphil> yea.. +6 day predictions are pretty unreliable, but it's moving that direction
[23:50] <iNatrium> fsphil: nope
[23:50] <fsphil> Are you anywhere near Stranraer SpeedEvil?
[23:51] <iNatrium> fsphil: should i enable the pictures strip for you?
