[02:02] <arko> this is just damn beautiful
[02:04] <arko> http://handya.co.nz/post/43198336217/texting-brick-phone
[02:04] <arko> hah neat
[02:20] <Randomskk> omg yay
[02:20] <Randomskk> https://randomskk.net/u/scores.png
[02:21] <arko> neat
[02:21] <arko> what is this?
[02:21] <arko> learning algo stuff?
[02:21] <Randomskk> my masters project
[02:21] <arko> :)
[02:21] <arko> what does this data mean?
[02:21] <Randomskk> so the rough outline is I'm simulating bacterial colonies running genetic models that hopefully form large-score pattern formation
[02:22] <SpeedEvil> a giraffe classifier?
[02:22] <W0OTM> iHAB-9 Launch video - http://www.youtube.com/watch?v=D1a6Lf3ElGs
[02:22] <Randomskk> e.g. it would be cool if the colony, having started off uniform and clonal, develops strong and robust patterning
[02:22] <Randomskk> where "patterning" might mean "forms spots" or stripes or similar
[02:22] <Randomskk> part of the project is therefore a genetic algorithm to mutate the bacterial genome towards better patterning
[02:23] <Randomskk> and part of that genetic algorithm is a cost function to evaluate the pattern content of a simulation run
[02:23] <Randomskk> and to train that cost function I've got a corpus of simulated reaction-diffusion results and animal skins that show the type of patterning I like
[02:23] <Randomskk> and have trained up a GMM on those
[02:23] <arko> wow
[02:23] <arko> very nice!
[02:23] <Randomskk> then I scored some other test images and some no-pattern images (the cloud noise scored -27 onwards)
[02:23] <Randomskk> and while the GMM hasn't seen any of the reject images
[02:23] <Randomskk> it still scores all of them lower than the desired patterns
[02:24] <Randomskk> better yet, the 'ideal' reaction-diffusion patterns have scored highest
[02:24] <Randomskk> so basically yes, SpeedEvil, it is a giraffe classifier :P
[02:24] <Randomskk> though it's not a classifier I hasten to add
[02:24] <Randomskk> as it gives a log likelihood for the input
[02:24] <Randomskk> not just a class label
[02:24] <Randomskk> which is crucial for a cost function
[02:25] <arko> oh good, at least your ideal is scoring highest :P
[02:25] <Randomskk> the scoring is exactly what I want
[02:25] <SpeedEvil> :-)
[02:25] <Randomskk> I'm concerned about overfitting
[02:25] <Randomskk> so I need a lot more data basically
[02:25] <Randomskk> have to troll flickr for a few days to find more animals
[02:25] <arko> how are you feeding back into the algo that it's correct or accurate?
[02:25] <Randomskk> arko: what do you mean?
[02:26] <Randomskk> basically a lower number here means it's more patterned
[02:26] <arko> right right
[02:26] <SpeedEvil> there is a market for cameras that will accurately look at certain body features, and keep them in focus.
[02:26] <Randomskk> so the genetic algorithm will consider every member of a generation and see which have the best patterns
[02:26] <SpeedEvil> and I don't mean faces.
[02:26] <Randomskk> then breed them
[02:26] <arko> hmm
[02:26] <Randomskk> so crossover+mutation, typically with some holdon to preserve low-scorers to prevent lock in to a small local optimum
[02:27] <Randomskk> the mutation and crossover change the strengths of RBS and degradation tags in the bacterial genome, and rearrange the genetic network itself (changing what promotors are controlled by what proteins, and what proteins are expressed where)
[02:27] <Randomskk> the proteins themselves can cross cell boundaries and diffuse through the simulated growth medium
[02:27] <Randomskk> (which is how the patterns should form)
[02:28] <arko> so those higher scoring ones -13 or so are simulations?
[02:28] <arko> im a bit confused
[02:28] <Randomskk> the first seven are simulations of a precise continuous differential equation
[02:28] <Randomskk> the first three are Turing patterns in fact
[02:28] <arko> oh
[02:28] <SpeedEvil> how accurately are you stimulating the bacteria?
[02:28] <Randomskk> and they represent the types of patterns I'd like to get
[02:29] <Randomskk> but they're simulations of just differential equations
[02:29] <arko> that a very highly ideal case correct?
[02:29] <Randomskk> not of bacteria
[02:29] <Randomskk> as it were, sure.
[02:29] <Randomskk> SpeedEvil: well.....
[02:29] <Randomskk> not 'very'
[02:29] <Randomskk> to start with the colonies will be static
[02:29] <arko> hmm
[02:29] <Randomskk> because I don't want to write a full biophysics simulator
[02:29] <arko> sure yeah
[02:29] <Randomskk> but I do _have_ a full biophysics simulator written in python+opencl, which is what all my other code is in
[02:29] <Randomskk> so I can plug into that
[02:29] <Randomskk> so a later part of my project is doing that
[02:29] <arko> ahh
[02:29] <Randomskk> in which case the accuracy becomes really quite good
[02:30] <arko> why not take actual bactera data?
[02:30] <Randomskk> as in, every bacterium is modelled as a body that divides and grows and strains and the chemical levels are all well done
[02:30] <SpeedEvil> I assume full biophysics doesn't mean to rhisome level
[02:30] <Randomskk> arko: because it's very very slow
[02:30] <SpeedEvil> an
[02:30] <SpeedEvil> ah
[02:30] <Randomskk> SpeedEvil: no, the biophysics is a rigid body per bacterium
[02:30] <arko> the processing of the data or getting that data?
[02:30] <Randomskk> the cell internals are still going to be differential equations
[02:30] <Randomskk> or possibly stochastic
[02:30] <SpeedEvil> ribosomes
[02:30] <Randomskk> arko: bacteria grow slowly
[02:30] <Randomskk> and creating genomes is very very slow
[02:30] <Randomskk> and lab work is slow and messy
[02:31] <arko> oh yeah, but there isn't some sample data from labs or people who have grown them?
[02:31] <Randomskk> well sure, but that won't be any help
[02:31] <Randomskk> no one's made a genome that develops pattern before or this project would be a bit pointless
[02:31] <Randomskk> I'll essentially be simulating many thousands/millions of genomes
[02:31] <Randomskk> you just can't make all those
[02:31] <arko> ohhhhhh
[02:32] <Randomskk> it's not a simulation of normal bacteria (though I can do that too and use it to validate my simulator)
[02:32] <Randomskk> but it's a simulation of bacteria carrying a synthetic genome
[02:32] <arko> sure yeah
[02:32] <Randomskk> to do my bidding
[02:32] <arko> ok this makes more sense now
[02:32] <Randomskk> and my objective is to find a synthetic genome that causes pattern expression
[02:33] <arko> which doesn't exist yet
[02:33] <Randomskk> right
[02:33] <arko> so you are building a detector, but is there going to be a creation of a synthetic genome that actually does this?
[02:34] <arko> are you working with bio people?
[02:36] <Randomskk> yea, working with http://www.haseloff-lab.org/
[02:36] <Randomskk> and, well, there might be
[02:36] <Randomskk> but it's not officially part of my project
[02:36] <arko> ahhhh

[07:39] <arko> lots of help from Daniel Richman
[07:39] <arko> I think chris also made a tutorial
[07:40] <daveake> Isn't someone making a VM?
[07:40] <arko> was...
[07:40] <daveake> oh
[07:40] <arko> at least i was
[07:40] <arko> then i got side tracked, not sure if anyone else is
[07:40] <daveake> Someone yesterday was talking about one
[07:40] <arko> i have a full dev environment if someone wants that vm
[07:40] <arko> buttload of tools
[07:40] <arko> predictor and hourly
[07:41] <costyn> arko: what was the goal of the vm?
[07:41] <costyn> arko: I mean, for public use?
[07:41] <costyn> or... ?
[07:41] <arko> im using it to add a few features to the predictor
[07:41] <arko> i made the vm for myself with plans to make it public, but the way it looks now, they are rewriting all of this
[07:41] <arko> so im not sure how useful it will be for long
[07:42] <arko> plus i dont want to throw anything out there without some permission or something
[07:42] <arko> etc etc
[07:42] <costyn> arko: the code is gpl
[07:42] <costyn> or do you mean something else?
[07:43] <arko> i dont know actually
[07:43] <arko> heh
[07:44] <arko> plus, the current vm isn't working very fast
[07:44] <arko> i added a feature that checks ground altitude on the way down
[07:45] <arko> it's slow, gonna optimize and clean it up
[07:45] <daveake> Fround altitude would be handy. My flight last week landed 300+m up and could have been 800
[07:45] <daveake> G
[07:45] <arko> yeah, uk is like 0m altitude :P
[07:46] <arko> so it works there
[07:46] <daveake> Nah that's Denmark :)
[07:46] <daveake> and Holland :)
[07:46] <costyn> arko: sounds like useful features. you could submit patches to the dev team
[07:46] <arko> but here with the mohave and other mountains, the predictor could be off

[10:39] <mfa298> HixWork: I think looking at the notes chrissstubbs made he disabled the gui in the vm.
[10:40] <griffonbot> Received email: Steve Aerospace "[UKHAS] Launch Announcement - XABEN41 - Tuesday 18th February - Worcestershire"
[10:41] <fsphil> you can reinstall it easily enough
[10:42] <mfa298> from what I remember in the notes he just changed the default runlevel in inittab.
[10:44] <mfa298> I didn't even comment on that in my notes as my default build is fairly minimal, no point in installing stuff you don't need.
[10:46] <Maxell> mattbrejza: yeah, and thats the problem. If someone doesn't like the way *I* translated it, they can onle use Dutch.
[10:53] <mattbrejza> are you a native speaker?
[10:53] <costyn> Maxell: I'm sure it'll be ok... do you want me to take a look whe you're done?
[10:53] <costyn> mattbrejza: he is yes
[10:56] <mattbrejza> your dutch will be better than someone who doesnt speak english well trying to work out the app
[10:57] <mattbrejza> there are a few strings that havnt been added to that strings.xml file yet, but theyre only one word things
[10:57] <Maxell> Ah, yeah. I'll put online what I have so far.
[10:58] <mattbrejza> thanks
[11:02] <Maxell> costyn: https://gist.github.com/anonymous/4976619
[11:02] <Maxell> Thats what I have so far. I'd preffer English, as my phone has the langue set.

[11:03] <costyn> Maxell: link doesn't work

[11:04] <costyn> Maxell: works now
[11:04] <Maxell> It's not yet done!
[11:04] <mattbrejza> i know, but then if someone wnats to continue they can start where you left off

[11:12] <daveake> Does it have special settings for Tesco Value burgers?
[11:13] <Darkside> horse meat?
[11:15] <HixWork> mfa298, got it sorted ta.
[11:15] <HixWork> Just need to work out how to access the vm from external machines nowe
[11:15] <gonzo_> really? Cooking with 5watts max?
[11:15] <HixWork> can see it on server using the VM ip in chrome
[11:15] <HixWork> forwarded ports on router but cant see externally now
[11:15] <HixWork> but it's running
[11:16] <HixWork> so just need to play with it and customise it for my launch locn
[11:16] <daveake> gonzo_ It says it charges capacitors ....
[11:16] <gonzo_> saw pics of a USB coffee maker. The guy had hald a dozen 4port usp cards in the pc to power it.
[11:16] <mfa298> setting up nat, always a fun exercise :p
[11:16] <daveake> hah
[11:16] <gonzo_> wondered why not just take the 5v off the pc psu direct
[11:17] <gonzo_> or even use..... mains?
[11:17] <daveake> Or, now here's a thing, why not make a 240V heater ...?
[11:17] <Maxell> gonzo_: with a piece of bacon on it, right?
[11:17] <costyn> gonzo_: mains? pfff... that is so last decade.
[11:18] <gonzo_> the whole usb power idea give me the willies anyway.
[11:18] <daveake> I don't think even my Pi payloads have anough power to cook the pre-launch bacon rolls
[11:18] yonas (53db861f@gateway/web/freenode/ip.83.219.134.31) left irc: Quit: Page closed

[11:19] <daveake> :)
[11:20] <costyn> mattbrejza: aha
[11:21] <HixWork> so NAT is the key to thius thing then right?
[11:21] <HixWork> this
[11:21] <costyn> HixWork: do you have it running in a private network now?
[11:22] <HixWork> yup - its fine, but no access externally from any other machine

[11:22] <mfa298> NAT is what you'll be configuring on your adsl router to make it available externally.
[11:22] <mfa298> i.e. the forwarded ports.
[11:23] <HixWork> well i've set port 3400 TCP and UDP to device 192.168.1.67 [VM] but nothing
[11:23] <HixWork> set rules in firewall to open port 3400 too
[11:23] <mfa298> do you mean port 3400 external to 3400 internal (or 80 internal)
[11:24] <mfa298> the VM is probably listening on tcp/80 (standard web port)
[11:24] <HixWork> ahh, i need to set 3400 external to 80 internal then?
[11:24] <mfa298> that would be my guess
[11:24] <HixWork> give it a go
[11:24] <mfa298> should only need tcp
[11:30] <HixWork> got it, and it had changed its IP to ....64 on restart, need to assign static to VM for future
[11:33] <HixWork> grrr hosting co take ages to apply URL changes

[12:04] <Maxell> Thats not all. :P
[12:04] <Maxell> costyn: mind quickly check it for any obvious errors?
[12:07] <mattbrejza> :D thanks
[12:20] <HixWork> any ideas on this? editing config.inc.php in vi terminal but when i type :q nothing happens
[12:20] <HixWork> also :q!
[12:20] <HixWork> they usually work or is this a centos thing
[12:21] <Randomskk> that should be okay
[12:21] <Randomskk> do you see any errors or messages
[12:21] <Randomskk> you might have a particular vim config that remaps : for instance
[12:21] <Randomskk> (personally I have ; remap to : and v.v. to save pressing shift so often)
[12:21] <cuddykid> HixWork: is it fairly easy to get it working?
[12:21] <HixWork> I've used a vm image
[12:22] <Brace> HixWork: use nano instead of vim if you're having problems with it
[12:22] <Brace> much easier to use :D
[12:22] <HixWork> how do i escape from vi though
[12:22] <HixWork> im trapped :/
[12:22] <Randomskk> haha
[12:22] <Randomskk> #1 top vim question ever
[12:22] <Randomskk> are you in insert mode
[12:22] <Randomskk> what happens when you type :q
[12:22] <HixWork> yeah
[12:22] <Randomskk> just press escape to leave insert mode
[12:22] <HixWork> it just sits there taunting me with :q on the screen
[12:23] <Randomskk> you need to press enter after :q too
[12:23] <Randomskk> so press escape a couple of times then press : and then q and then enter
[12:23] <Randomskk> you might have to :q! if you have made unsaved changes
[12:23] <Brace> as the others have said, hammer esc a bunch to times to ensure you're definitely in command mode
[12:23] <HixWork> yup got it, thanks
[12:23] <HixWork> got all claustrophobic in there L)
[12:24] <Brace> HixWork: it's a linux rite of passage to get stuck in a text editor
[12:25] <HixWork> i've been there before, but remembered :q!
[12:25] <HixWork> forgot esc though
[12:25] <HixWork> :q! is something you'll never forget
[12:28] <mfa298> best one I've had was using a a proper serial console where we opened up vi to edit a file and then found there was no esc key on the keyboard.
[12:29] <Laurenceb> dude, use nano
[12:30] Action: mfa298 waits for someone to suggest emacs
[12:30] <daveake> edlin
[12:30] <Brace> a butterfly
[12:35] <fsphil> direct neural interface
[12:36] <HixWork> my console has limited window, how do i get ps -ef to pause until i hit a key to scroll
[12:36] <Brace> | less
[12:36] <daveake> | more
[12:36] <fsphil> | just enough
[12:36] <HixWork> ta
[12:36] <mfa298> | less
[12:36] <daveake> lol
[12:37] <HixWork> | thanks
[12:37] <fsphil> put that in your pipe and pipe it
[12:37] <mfa298> or install putty and ssh into the vm and you can scroll the window
[12:37] <daveake> hose | ban
[12:38] <fsphil> it's been the wettest winter in ages, you totally won't have those for weeks yet
[12:38] <daveake> It'll be the wrong sort of rain
[12:38] <mfa298> nah, there'll probably be a ban because the ground is too wet
[12:39] <HixWork> putty, plan mfa298
[12:39] <LazyLeopard> They'll declare a drought again...
[12:40] <HixWork> pi'd p|r
[12:42] <mfa298> putty is usually around the 2nd thing I install (straight after something thats not IE)
[12:42] <daveake> good plan
[12:42] <daveake> I only ever run IE to download its replacement
[12:42] <fsphil> isn't that was it's designed for?
[12:42] <fsphil> what*
[12:43] <daveake> Hope so
[12:43] <mfa298> I think that's the only reason it's still in windows
[12:43] <fsphil> the firefox downloader
[12:43] <daveake> It can just about manage that
[12:44] <fsphil> the browser ballet thing was handy for that, until they accidently on purpose removed it
[12:45] <HixWork> IE is like the fire escape, it's there to use to get out in an emergency
[12:45] <fsphil> ballot
[12:45] <fsphil> it's not a dance
[12:45] <daveake> Use In Extremis
[12:45] <HixWork> putty hasd made things all puurdy again, i can use mouse to select and less tabbing
[12:45] <daveake> Yeah putty is a nice little tool
[12:45] <fsphil> someone should totally do a Browser Ballet
[12:46] <HixWork> didn't think to use it fo rthe VM though cheers mfa298
[12:46] <HixWork> right liunch bbl
[12:46] <HixWork> lunch
[12:46] <daveake> Anyone who clicks the IE button then gets asked questions about their sanity
[12:46] <mfa298> it can also act as a serial console (useful for testing out gps etc)
[12:46] <daveake> yup
[12:46] <daveake> So kinda like HyperTerm
[12:47] <daveake> except it works
[12:47] <fsphil> there are not too many good terminal programs for linux
[12:48] <mfa298> I've tended to use minicom for serial access from linux (but remove most of it's default strings)
[12:48] <fsphil> I really don't like minicom
[12:48] <fsphil> it seems so awkward and icky
[12:49] <fsphil> just old I think
[12:49] <mfa298> It's been good enough for what I've wanted.
[12:49] <fsphil> I used gtkterm for a while but it's got quite a few bugs
[12:49] <Laurenceb> fsphil: screen
[12:49] <fsphil> screen can connect to serial ports
[12:49] <Laurenceb> heh
[12:50] <mfa298> but I've not used it that often. it's usually only when I've mucked up the router/wireless config horribly
[12:50] <fsphil> haha yea
[12:50] <mfa298> I've got a feeling there's a putty port for linux although it's not something I've ever tried.
[12:50] <fsphil> think you're right
[12:51] <mfa298> I hardly ever install a gui on linux - ssh is a good enough gui for what I do :D
[12:52] <daveake> All my Linux machines are either servers or trackers, so I don't use GUIs on them either
[12:52] <daveake> Well, the servers do have webmin
[13:03] <mfa298> nice headline on the bbc news: BBC news disrupted due to strike action.
[13:03] <mfa298> obviously not that disrupted or I'd be looking at a test pattern
[13:04] <fsphil> the question is, who wrote the story about the strike
[13:04] <LazyLeopard> Heh. No "Today" on Radio 4 this morning, though.
[13:04] <fsphil> it's just the journalists that are striking
[13:04] <LazyLeopard> Whole bunch of repeats instead...
[13:05] <fsphil> so they'll still be on the air
[13:05] <fsphil> though Test Card F is better than a lot of those home improvement shows

[14:31] <craag> I run it on a VPS with 512MB ram, a 400MHz CPU-share and a 100Mb/s internet connection (tested). The predictions only take about 8 minutes, it's the downloading that takes ages.
[14:32] <mattbrejza> craag: where is your launch location set to?
[14:32] <mfa298> I've just got it all in cron and forget about it now.
[14:32] <mattbrejza> also noaa might limit download speed, so it might not be as bad on a bad connection
[14:32] <craag> Ermm not sure at the moment, have't been using it. Was about to set it up for SHARP.
[14:33] <NigelMoby> would be good if you could specify a diff template aswell via the browser url
[14:34] <mfa298> NigelMoby: I was thinking the same thing.
[14:34] <mattbrejza> if i could be bothered (with i cant) it would run for lots of sites rather than everyone who wants an hourly setting it up for themselves
[14:34] <mfa298> sounds like another thing to add to the list to think about doing
[14:34] <NigelMoby> yup
[14:35] <NigelMoby> mattbrejz good plan, have a web form that does params for the template and spits out a unique url...or something...
[14:36] <mfa298> although I keep wondering how much to do with the prediction stuff as I thought there were plans to overhaul the whole lot.
[14:37] <mattbrejza> someone elses job, i have enough programming to do atm
[14:37] <craag> mattbrejza: Mine's now set up for the SHARP site near Evesham, won't run again til 1600 though.
[14:38] <mattbrejza> persumably the new forest is too unreliable for them?
[14:38] <HixWork> mattbrejza, the wiki is lackng on info for hourly
[14:39] <craag> Yeah, I think they had issues with getting NOTAMs for it. and of course the wind is in the wrong direction at the moment.
[14:39] <mattbrejza> indeed, but most of the uk must be covered by now
[14:39] <mattbrejza> craag: really? we had no issues for it :/
[14:39] <mattbrejza> but yea wind
[14:39] <mattbrejza> however it either will land on land of it wont most of the time
[14:39] <mattbrejza> you cant really overshoot land like in cam
[14:41] <craag> I'm not exactly sure, haven't had much to do with it, Andrew's been helping them out. I'm hoping to possibly piggyback my 868 on their next flight though.
[14:41] <mattbrejza> protip: have it seperate to their box so they cant moan at you for jamming their gps if something goes wrong
[14:42] <craag> Yes, it will be very seperate. at least 5 metres of cord I'm thinking! Plus there's also their uplink to jam.
[14:43] <cuddykid> damn - connection to server has been dropped because of my inactivity - is there anyway to tell when the grabdata cron is complete? If not, I'll just leave it an hour or so
[14:43] <mattbrejza> look at when web/hourly is updated with ls -l
[14:43] <daveake> ps -ef and look for it?
[14:44] <cuddykid> cheers
[14:44] <daveake> or ps -ef | grep grabdata
[14:45] <mattbrejza> btw craag did you see if usb soundcards work with android and hte app?
[14:46] <craag> mattbrejza: I took a look. But it seems you have to build libusb into the app? I got a 'USB Sound Tether Test' app that worked with the USB soundcard, but nothing extra shows up in system settings and your app doesn't seem to recognise it.
[14:47] <craag> The 'USB Sound Tether Test App' claimed to use libusb to talk to the soundcard directly.
[14:47] <mattbrejza> hmm ok
[14:47] <mattbrejza> i was under the impression souncards were supposed to be supported by the kernel and so work with whatever wanted audio
[14:47] <mattbrejza> would seem not
[14:48] <costyn> is there a prediction for Steve's launch tommorow? Any ideas which direction it'll be heading?
[14:48] <craag> I'm just about to head out now, but I'll take another look later.
[14:49] <mattbrejza> thanks for tryign anyway
[14:49] <mattbrejza> laters
[14:49] <mattbrejza> costyn: south and east a little

[15:34] <UpuWork> thats the moon
[15:35] <mattbrejza> did you work out if that dot is a star or a hot pixel UpuWork ?
[15:35] <UpuWork> well
[15:35] <UpuWork> Everyone decided it was a duff pixel
[15:36] <UpuWork> but it doesn't occur in any other image
[15:36] <UpuWork> its bright though
[15:36] <mattbrejza> also its brighter than the moon
[15:36] <UpuWork> yep
[15:36] <NigeyS> UpuWork, easy way to check, load up stellarium and set the date to the date of the image
[15:36] <UpuWork> 1/10/11 @ 14:45
[15:36] <Elwell> 's a nice pic upu - what's the river?

[15:37] <Elwell> ah K - so looking southwestish
[15:38] <UpuWork> the big gap is the English Channel
[15:38] <daveake> Too big :p
[15:38] <Elwell> yeah I guessed once you said it was the thames :-)
[15:38] <NigeyS> if thats not a duff pixel, it could possibly be a planet or a star, if its a planet, likely jupiter.
[15:39] <Elwell> deathstar...
[15:39] <NigeyS> lol
[15:39] <UpuWork> I don't think its dead pixels
[15:39] <UpuWork> as its shaded
[15:40] <daveake> They're normally coloured for a start
[15:40] <NigeyS> yup
[15:40] <NigeyS> have you got a telem string for about that time ?
[15:42] <UpuWork> http://i.imgur.com/fAfJaEe.jpg
[15:42] <UpuWork> dead pixel ?
[15:42] <UpuWork> no telemetry
[15:42] <UpuWork> but I could dig out the original image
[15:44] <UpuWork> http://i.imgur.com/psNWl4g.jpg
[15:44] <UpuWork> thats raw
[15:44] <Elwell> does the EXIF have an altitude field?
[15:44] <UpuWork> no
[15:44] <UpuWork> let me go have a look and see if I can find the original un-altered image
[15:44] <UpuWork> may take me a while as it did 8000 images :)
[15:44] <mattbrejza> i tend to add lat/long/alt to photos after launch using gps data though
[15:45] <daveake> I was thinking of getting my Pi tracker to do that as the photos are taken

[18:03] <mattbrejza> water it weekly
[18:03] <mattbrejza> prune in the winter
[18:03] <mfa298> as long as there's a cron job to keep it updated you're probably mostly there.
[18:04] <Hix> mattbrejza: do i need a | or a watering can
[18:04] <Hix> mfa298: havnae got a clue about the cron job, how would I check?
[18:04] <mfa298> as chris used my notes the cron is probably done (look for /etc/cron.d/hab)
[18:05] <Hix> ok ta
[18:05] <mfa298> it's probably got a single line in it along the lines of:
[18:05] <mfa298> 30 */6 * * * root cd /opt/cusf-landing-prediction && ./scripts/fetch-run-cronjob.sh
[18:06] <mfa298> which says run it every 6 hours at 30mins past the hour (ie. 0030, 0630, 1230, 1830)
[18:07] <Hix> 0 */3 * * * root cd /opt/cusf-landing-prediction && ./scripts/fetch-run-cronjob.sh
[18:08] <Hix> so every 3 on the hour then.
[18:08] <Hix> might cut that back to 12 hours
[18:08] <mfa298> yep, although I think the gfs data only comes out 4 times a day.
[18:09] <Hix> hmm, i need to monitor when it runs and how long it takes, also how it hammers the home network
[18:09] <Hix> not fair to kill it for everyone
[18:09] <NigeyS> it wont hammer the network
[18:09] <Hix> 1.5Mbps?
[18:09] <mfa298> I think it's more cpu intensive than network intensive
[18:09] <NigeyS> the gfs files are only <300k each, and its dog slow at downloading them
[18:10] <Hix> ahh ok
[18:10] <Hix> it's a 1GHZ with 1Gb so should be ok no?
[18:11] <mfa298> my vm is set to 1vcpu and 768mb ram and I've not seen a problem

[19:55] <mattbrejza> also wtf 4096? from the code: buffsize = Math.max(buffsize, 3000);

[19:55] <craag> lol
[19:56] <craag> audio comes up on the waterfall :)
[19:57] <mattbrejza> i will be interested to see if it actually decodes, as something weird is happening
[19:57] <craag> hmm crashed after a while of trying to get it to decode
[19:57] <mattbrejza> can you send that? itll be different
[19:59] <mattbrejza> oh ive just seen how buffer ends up being 4096 (kinda)
[19:59] <craag> Can't send a report from an apk.

[19:59] <craag> Also hasn't crashed again, but can't get it to decode. (Using microphone in front of laptop speakers)
[20:00] <craag> decoded! :D
[20:00] <mattbrejza> so kinda working
[20:01] <craag> Yep, decoded successfully, came up with 7,2 data format.

[20:02] <craag> Didn't crash that time..
[20:02] <mattbrejza> well when i next update the app on the store you can send the crash report
[20:02] <craag> yep
[20:04] <craag> Thanks for fixing it!
[20:04] <mattbrejza> its not really fixed :P
[20:05] <craag> Oh.. you stripped out some sanity check or?
[20:05] <mattbrejza> well the error is an out of bounds (or an array one)
[20:05] <mattbrejza> but i havnt worked out why it goes out of bounds
[20:06] <mattbrejza> so i just put a if (j < len){} check in
[20:06] <mclane> mattbrejza: I am trying your new app from Google play; is there a new version?
[20:06] <craag> Oh right, v weird..
[20:06] <mattbrejza> well theres one that has a minor bug fix you probably wont find mclane
[20:06] Action: craag => dinner.
[20:06] <mattbrejza> craag just has annoying devices :P
[20:07] <craag> :P
[20:07] <NigeyS> lol
[20:08] <Lunar_Lander> did someone compare the ublox GPS performing with an active and a passive antenna?
[20:08] <mclane> ok
[20:09] <mclane> stupid question: how can I move the green lines on the waterfall to match the signal?
[20:10] <mattbrejza> its automatic
[20:10] <mattbrejza> although a future version will have manual control
[20:10] <mclane> but it does not work
[20:10] <Lunar_Lander> wait
[20:10] <Lunar_Lander> green lines in dl-fldigi?
[20:10] <mattbrejza> it is a bit iffy still, but works for most
[20:10] <Lunar_Lander> isn't the cursor red?
[20:11] <mattbrejza> do you have a recording mclane ?

[20:11] <Lunar_Lander> ah
[20:11] <mclane> no
[20:11] <mattbrejza> are you playing through the mic? that tends to not work as well
[20:12] <griffonbot> Received email: SP9UOB "[UKHAS] Launch Announcement - Sunday 24th February - SPUTNIK-3,
[20:12] <Lunar_Lander> mattbrejza, so that is dl-fldigi for android?
[20:12] <mattbrejza> its not related to fldigi, its a completely new decoder
[20:12] <mattbrejza> but yea decoder and mapping for android
[20:12] <mclane> yes through the mic
[20:12] <Lunar_Lander> ah
[20:12] <Lunar_Lander> does it work like dl-fldigi?
[20:12] <mclane> I will have to look for a suitable cable
[20:13] <mattbrejza> yea unfortinetly the cable is the annoying thing here
[20:13] <Lunar_Lander> because one of my mates has a Samsung tablet with android and when he first asked about such a thing I told him that unfortunately dl-fldigi isn't for android
[20:13] <mattbrejza> Lunar_Lander: the decoder uses similar methods to fldigi but it does some things differently
[20:13] <Lunar_Lander> ah
[20:14] <Lunar_Lander> but you can decode a balloon with it
[20:14] <mattbrejza> from a users point of view its automatic appart from selecting the baud
[20:14] <mattbrejza> yes its ment for balloon tracking
[20:14] <Lunar_Lander> cool!
[20:16] <mattbrejza> do you have anythnig android?
[20:16] <Lunar_Lander> no but two friends of mine
[20:16] <Lunar_Lander> they say thank you
[20:16] <Lunar_Lander> :D
[20:16] <mattbrejza> heh :D
[20:18] <Lunar_Lander> so a thank you from Germany and one from Slovenia
[20:18] <Lunar_Lander> :)

[20:29] <fsphil> mattbrejza: do you look for the start bit each byte?
[20:29] <mattbrejza> there are two methods, one looks for the start bit, one looks for $$ and counts bits
[20:29] <mattbrejza> the second being not tested so much
[20:30] <fsphil> good idea
[20:31] <fsphil> fldigi just looks for the start bit each time, which I suspect is how it's so tolerant to timing errors
[20:31] <mattbrejza> yea mine really isnt
[20:31] <fsphil> it's a good thing too
[20:31] <mattbrejza> it also uses that to sync between the filtered waveform and bits?
[20:31] <fsphil> stricter timing makes a better signal, easier to decode
[20:31] <mattbrejza> while i use an early-late synchroniser
[20:32] <fsphil> it scans for the start bit after filtering
[20:32] <mattbrejza> which means 1.5 stop bits will really not work well at all
[20:32] <fsphil> it actually ignores stop bits
[20:33] <fsphil> well it reads the first one
[20:33] <fsphil> then waits for the start, regardless of the setting in the modem config
[20:33] <mattbrejza> yea so does mine, but if there are non integer stop bits the bit sync will have to try to correct for 1/2 a bit error each time
[20:33] <mattbrejza> each byte
[20:33] <fsphil> have you compared it to fldigi's decoder with a weak (but well timed) signal?
[20:34] <mattbrejza> its about the same, but i havnt done anything properly yet
[20:34] <mattbrejza> fldigi is better at spinning payloads mind you because you can open the filters a bit
[20:34] <fsphil> I've not got the cable to test it yet, but I'll get a play with it soon hopefully
[20:35] <mattbrejza> well at some point ill get a java pc version which will probably be easier to test with
[20:35] <fsphil> would it work with a usb sound card?
[20:35] <mattbrejza> on android?
[20:35] <fsphil> yea
[20:36] <mattbrejza> nope :(
[20:36] <fsphil> aw
[20:36] <mattbrejza> android 4.1 supports usb audio out
[20:36] <fsphil> I kinda hoped android would make that automatic
[20:36] <mattbrejza> but not in :/
[20:36] <fsphil> no fun
[20:36] <mattbrejza> it is possible if i wanted to write a soundcard driver though
[20:36] <fsphil> there's an android app that can drive the rtlsdr
[20:37] <mattbrejza> yea ive seen that, i reckon it would be possible to use that if i get round to it
[20:41] <Gadget-Mac> Any pcb folks in ?
[20:42] <mattbrejza> ask away
[20:44] <Gadget-Mac> Wondering if there's an easy way to make an 80mmx90mm gerber file from eagle into a 100mmx100mm PCB with dead space round the edge
[20:45] <mattbrejza> the only way i know how is to make sure the eagle board only has stuff in a 80x90 space
[20:45] <mattbrejza> i dont know and gerber editors enough to do it in one
[20:45] <Gadget-Mac> Time to hit google I think

[21:12] <Upu> what radio are you using to transmit with ?
[21:13] <sjohn> it is a ntx2
[21:13] <fsphil> good choice

[21:13] <Upu> getting it transmitting RTTY ?
[21:13] <sjohn> correct
[21:13] <Upu> and that decoded ok ?
[21:14] <sjohn> yes, i also bought a gps module

[21:14] <Upu> ok so what isn't working ?
[21:14] <Upu> good choice
[21:15] <sjohn> i am struggling to put the lat/long.alt/time string onto the data string
[21:15] <Upu> ok what are you using to get the GPS information from the GPS chip ?
[21:16] <sjohn> i was on the tinygps website, and i got an example from the arduino programmer
[21:16] <craag> mattbrejza: 4096 :P
[21:16] <mattbrejza> wat
[21:16] <mattbrejza> i think you have a broken Math library
[21:17] <craag> oh, funky.
[21:17] <mattbrejza> which would also explain why Math.ceil should give 615 but yours seems to give 614
[21:17] <Upu> ok sjohn
[21:18] <Upu> well TinyGPS works so its just a case of building up a telemetry string with the required variables in it
[21:18] <Upu> go paste what you have done to pastebin.com
[21:18] <Upu> and link it
[21:19] <mattbrejza> craag: this is the code thats somehow giving 4096 http://pastie.org/6217873
[21:19] <sjohn> ok
[21:21] <mattbrejza> craag: ideally i would step through line by line of the debugger, but it does seem its your device
[21:21] <craag> mattbrejza: Oh wow. Ok, I don't think a factory reset will fix that, so I'll have to wait for the JB update (soon [tm]) and try it again then.
[21:22] <mattbrejza> if i get the project working on my work pc you can come and debug next time you're near 4002
[21:23] <mattbrejza> wait im being stupid
[21:24] <mattbrejza> oc Math.max(buffsize, 3000); can return 4096
[21:24] <craag> I had just googled that.
[21:24] <craag> But 4096 is a lot larger than you've seen on other devices?
[21:24] <mattbrejza> why yhe min buffer size is so large i dont know
[21:25] <mattbrejza> it would normally be <3000
[21:25] <mattbrejza> i dont know what a normal AudioRecord.getMinBufferSize would be (other than < 3000)
[21:26] <mattbrejza> however why you get the initial error i dont know, if tried running that method with every length of input array and it never crsahes
[21:27] <craag> Would that be worth debugging?
[21:28] <arko> afternoon, gentlemen
[21:28] <arko> i am the hal9000 computer
[21:28] <mattbrejza> well i can just step through line by line and see what gives an unexpected result

[21:37] <fsphil> I thought they where code
[21:38] <fsphil> one comment, you're transmitting the variable DATASTRING, before it contains anything
[21:40] <sjohn> how so, does that code have to be within the encode bracket
[21:40] <fsphil> it might be better to put the code that formats and transmits the string at the end of the piece of code that processes the tinygps result
[21:40] <Upu> cheers fsphil just sorting tracker out for tomorrow
[21:40] <fsphil> np
[21:41] <fsphil> sjohn: so the sprintf() and rtty_txstring() calls, move then to the end of your if(gps.encode(GPS.read())) BLOCK

[21:43] <fsphil> yea there's a few functions that are not called
[21:44] <Upu> oo fancy
[21:44] <sjohn> which functions are not called?
[21:45] <fsphil> the ones in bertrik's pastebin
[21:45] <fsphil> wouldn't worry about that just yet
[21:45] <sjohn> oh lol
[21:45] <fsphil> you might need some of those later
[21:45] <bertrik> cppcheck can be really helpful for finding silly mistakes, and it's very easy to run, no complicated setup or anything like that
[21:46] <fsphil> new to me too bertrik, ta :)
[21:46] <bertrik> the stuff it found is mostly harmless
[21:46] <fsphil> yea the code isn't too bad
[21:46] <fsphil> just that missing brackets thing and the transmit code being in the wrong place
[21:47] <sjohn> i moved the rtty and sprintf to the end of the encode block....
[21:48] <sjohn> but which brackets am i missing
[21:48] <fsphil> after if (gps.encode(GPS.read()))
[21:49] <fsphil> an if() without any braces (I think that's what { } is called) will only apply to the next single instruction
[21:49] <lz1dev> yes
[21:49] <fsphil> so in this case the if() only applies to gps.f_get_position(&flat, &flon, &age);
[21:49] <sjohn> oh yeh, silly mistake

[21:51] <Upu> sjohn as you're using Software serial to talk to the GPS (bleurgh) you will need to disable interupts before you transmit and re-enable them once done
[21:52] <fsphil> ooh yes
[21:52] <Upu> software serial uses interupts
[21:52] <Upu> and it mucks up the timing of the RTTY delays
[21:52] <mattbrejza> lol arduino
[21:52] <Upu> so before rtty_txstring(DATASTRING);
[21:53] <Upu> put cli();
[21:53] <Upu> and after put sei();
[21:53] <Upu> cli(); // disable global interrupts

[22:13] <fsphil> 22:13 UTC
[22:13] <arko> ah
[22:14] <arko> wow, eroomde how long have you been awake?
[22:14] <arko> oh man this is gonna suck when i visit EU
[22:14] <fsphil> it's no fun
[22:15] <arko> :/
[22:15] <fsphil> but you'll adjust within a few days
[22:15] <eroomde> yep
[22:15] <fsphil> I've also heard that getting drunk helps
[22:15] <eroomde> let's hope
[22:15] <eroomde> had a bottl3 of red and a bottle of prosecco
[22:15] <eroomde> courtesy of housemate
[22:15] <eroomde> tis my bday today
[22:15] <fsphil> happy birthday!

[22:16] <fsphil> was there cake?
[22:19] <Lunar_Lander> happy birthday ed

[22:25] <Upu> happy birthday eroomde
[22:26] <sjohn> how do i get the checksum, i am getting "$$SJohn,22:25:01,51.5136,+0.0194,0*C3B3"
[22:27] <Willdude123> Happy Birthday Ed!
[22:27] <eroomde> ty all
[22:28] <Willdude123> I take it you're back from the US now.
[22:28] <fsphil> how are you generating that sjohn?
[22:29] <Upu> that is a check sum sjohn :)
[22:29] <sjohn> sprintf(checksum_str, "*%04X\n", checksum); strcat(DATASTRING,checksum_str);
[22:29] <eroomde> Willdude123: yes, as of yesterday
[22:30] <Willdude123> How was the JPL?
[22:30] <fsphil> how are you generating checksum_str?
[22:30] <fsphil> or checksum even
[22:31] <Upu> checksum isn't correct for that string
[22:31] <Upu> should be DF64
[22:31] <sjohn> i just used the one on the wiki page
[22:31] <Upu> pastebin all your code again
[22:32] <Willdude123> Night! I'm off to bed.
[22:32] <Upu> night will
[22:32] <fsphil> g'nite!
[22:32] <Upu> You need to see Ed's pictures btw :)
[22:32] Action: fsphil enables jealous mode
[22:32] <Willdude123> Which ones? Link me.

[22:32] <sjohn> http://pastebin.com/YqM2q4mh
[22:33] <Willdude123> Are random tourists allowed to do that? :)
[22:33] <fsphil> you're not actually generating any checksum there sjohn
[22:33] <Upu> snprintf(DATASTRING, sizeof(DATASTRING), "*%04X\n", gps_CRC16_checksum(DATASTRING));
[22:34] <fsphil> it's commented out
[22:35] <Upu> actually
[22:35] <fsphil> you need something along the lines of, checksum = gps_CRC16_checksum(DATASTRING);
[22:35] <Upu> sprintf(txstring, "%s*%04X\n", txstring, gps_CRC16_checksum(txstring));
[22:35] <Upu> is what I use
[22:35] <Willdude123> eroomde: Wow... Some of those photographs are so good you could probably even sell them.
[22:35] <fsphil> I'm iffy on calling sprintf with its output as one of its inputs :)
[22:35] <sjohn> yh i commented it out, it was giving me a conversion error
[22:36] <Upu> that comment probably made Ed very happy
[22:36] <fsphil> so the variable checksum is never given any value
[22:36] <Upu> replace it with : snprintf(DATASTRING, sizeof(DATASTRING), "*%04X\n", gps_CRC16_checksum(DATASTRING));
[22:36] <Upu> I think that should work
[22:37] <fsphil> nope
[22:38] <Upu> sprintf(DATASTRING, "%s*%04X\n", DATASTRING, gps_CRC16_checksum(DATASTRING));
[22:38] <Lunar_Lander> eroomde, cool you had KITT for driving https://secure.flickr.com/photos/eroomde/8476717507/in/photostream/
[22:38] <fsphil> possibly unpredictable
[22:38] <Upu> in what way fsphil ?
[22:38] <Upu> do I need to change my code ? :)
[22:38] <eroomde> wtf?
[22:38] <eroomde> this is kitt
[22:38] <eroomde> http://eur.i1.yimg.com/eur.yimg.com/i/de/mov/kult14.jpg
[22:38] <Lunar_Lander> ah
[22:39] <Lunar_Lander> didn't you watch Knight Rider 2008?
[22:39] <arko> ewww
[22:39] <eroomde> no of course not
[22:39] <eroomde> be serious
[22:39] <Upu> lol
[22:39] <Upu> ah Ed is back :)
[22:39] <Lunar_Lander> btw https://www.youtube.com/watch?v=XZwkhPUfAfE&feature=related
[22:39] <fsphil> there's only one KITT
[22:40] <Lunar_Lander> computers are serious too, Michael
[22:41] <chrisstubbs> Been playing with google API and jpgraph :) http://chris-stubbs.co.uk/extras/maps/losgraph/
[22:41] <Lunar_Lander> btw it is funny how many glitches were in the dashboard
[22:42] <Lunar_Lander> in the first episode featuring Goliath the truck, the RPM meter like is just counting down from 99 to 00 and then resetting
[22:42] <Lunar_Lander> xD
[22:42] <gonzo_> I watched it once or twice in the early 80's
[22:42] <gonzo_> was more of an A team fan really
[22:43] <eroomde> hilarious
[22:43] <Lunar_Lander> and I never got what the display "Propagation Delay Hrs" meant
[22:43] <Lunar_Lander> from 0 to 30
[22:43] <gonzo_> round trip to saturn?
[22:43] <Lunar_Lander> so some propagation was delayed from 0 to 30 hours
[22:43] <Lunar_Lander> xD
[22:43] <gonzo_> or trying to ket some cuttings to take in the greenhouse
[22:43] <Willdude123> I'm actually going to bed now, as much as I like Ed's wonderful pictures.
[22:44] <fsphil> haha
[22:44] <fsphil> g'nite again!
[22:45] <Lunar_Lander> the best thing was maybe that KITTs monitors usually showed things where he couldn't have seen things
[22:45] <sjohn> thanks guys for the help, gbye
[22:45] <Lunar_Lander> i.e. cars driving off or onboard cameras on other cars and so on
[22:45] <Upu> night sjohn

[22:46] <fsphil> you saying it was faked Lunar_Lander?
[22:47] <Lunar_Lander> xD

[22:47] <Lunar_Lander> the arch thing is fully lit
[22:48] <Lunar_Lander> still the digits show 22 and are actually, as I said counting from 75 to 00
[22:48] <eroomde> yes that pretty much ruined the 80's for me
[22:50] <arko> hmm
[22:50] <arko> i need to get this webcam live
[22:50] <arko> time to reimage this machine, then setup a server
[22:51] <arko> we may need help naming them
[22:51] <arko> :P
[22:52] <fsphil> lizard001
[22:52] <arko> haha
[22:52] <fsphil> you can guess the rest
[22:52] <Lunar_Lander> btw
[22:52] <Lunar_Lander> I can tell you an interesting thing
[22:52] <arko> Generic Lizard Unit SN0001
[22:52] <fsphil> haha
[22:53] <arko> i love it
[22:53] <arko> done
[22:53] <Lunar_Lander> I set up an arduino Uno, BMP085, DS18B20, light sensor, level shifter and SD card
[22:53] <Lunar_Lander> ran those from four alkaline AA batteries
[22:53] <arko> there is a second one, i guess it could just be SN0002
[22:53] <Lunar_Lander> and when I came back to the setup today, it still ran
[22:53] <Lunar_Lander> it ran the whole 70 hours
[22:53] <Lunar_Lander> and maybe could have continued a little more
[22:53] <eroomde> ok so launch it now
[22:54] <Lunar_Lander> the battery voltage had dropped from about 7 V to 4.9 V
[22:54] <eroomde> don't do anymore tests
[22:54] <Lunar_Lander> that wasn't a balloon test that was something else
[22:54] <Lunar_Lander> tomorrow I want to sign us up with flight safety
[22:54] <eroomde> cool
[22:54] <Lunar_Lander> tell them the mass of payload and so on
[22:54] <fsphil> actually if we're going to be accurate, there should be an SN000
[22:54] <fsphil> +0
[22:54] <arko> oh
[22:54] <Lunar_Lander> but I ran into a big error again
[22:54] <arko> thats a good idea
[22:55] <Lunar_Lander> I recorded a data string every 5 seconds
[22:55] <Lunar_Lander> and at 70 hours run time, well, that is more than 32000 lines, so the counter overflowed
[22:55] <Lunar_Lander> which makes the analysis crappy
[22:55] <Lunar_Lander> me, the master programmer
[22:55] Action: Lunar_Lander hits his forehead
[22:56] <eroomde> you remember the lessons our learnt the hard way
[22:56] <eroomde> you*
[22:56] <Lunar_Lander> yea
