[19:11] <edmoore> hi all
[19:11] <fergusnoble> hi edmoore
[19:12] <edmoore> yo
[19:12] <edmoore> how's the work?
[19:12] <edmoore> fergusnoble: this teddy bear thing seems to have resonated with people
[19:12] <edmoore> in a big way
[19:12] <fergusnoble> yeah, it seems good
[19:12] <fergusnoble> who've you been talking to?
[19:13] <edmoore> i showed dr. hicks as he loves CUSF - he basically provided the impetus and money for its foundation
[19:13] <fergusnoble> works going ok, had my last supervision this evening
[19:13] <edmoore> he sent it to the master, and the master seems to have sent it to the world
[19:13] <fergusnoble> awesome
[19:13] <fergusnoble> are you still completely buried?
[19:13] <edmoore> getting calls from uni press offices and up
[19:13] <edmoore> i had 2 supervisions this afternoon
[19:13] <edmoore> now i just have the friday deadline
[19:14] <fergusnoble> cool
[19:18] <edmoore> you?
[19:18] <fergusnoble> edmoore: rjharrison is going to beat us to a zero pressure launch :/
[19:19] <fergusnoble> ive just got a lab report left, due for monday
[19:19] <edmoore> how?
[19:19] <fergusnoble> he was saying he will be ready in a few weeks
[19:19] <edmoore> how is he making one?
[19:19] <edmoore> if he announces a date, we chould just launch the squid the day before
[19:19] <fergusnoble> im not sure, i think he found something he is repurposing as an envelope
[19:20] <fergusnoble> hehe, its not a race, good for him, it will be really cool
[19:20] <edmoore> but we should still beat him :p
[19:21] <edmoore> I hope he reads this in the logs
[19:21] <fergusnoble> we have been working on it for over a year now, the squid was build almost exactly a year ago
[19:21] <edmoore> yeah - scary
[19:22] <fergusnoble> ok, i should go cook some dinner
[19:22] <fergusnoble> bye

[22:43] <natrium> a few years ago
[22:43] <Laurenceb> I'm trying to learn atm
[22:43] <Laurenceb> looks quite easy
[22:44] <Laurenceb> stupidly easy in fact
[22:45] Laurence1 (i=zeusbot@lister.antycip.co.uk) joined #highaltitude.
[22:45] <Laurence1> its like a cross between basic and html
[22:46] <natrium> yeah
[22:46] <natrium> you just describe how hardware is connected
[22:47] <Laurence1> unfortunately fpgas arent a magic bullet
[22:48] <Laurence1> theres a lot of limits to what you can do
[22:48] <Laurence1> 1 million gates in an fpga is not equal to one million physical gates

[23:44] <Laurence1> if I'm trying to fit a function of the form a*exp(b*x) to some data
[23:44] <Laurence1> is there a way to do this without storing the data?
[23:45] <Laurence1> i.e. run the fitting function each time a new data point arrives
[23:50] <edmoore_> markov, you mean
[23:51] <edmoore_> I often wonder this and I'm not sure - I guess just some kind of moving average
[23:52] <edmoore_> so get 'a' by the average euclidean distance between the last (say) 4 data points
[23:53] <edmoore_> and something more cunning for the exponential bit
[23:54] <Laurence1> hmm yeah
[23:54] <Laurence1> basically I'm thinking for the optimised waypoint calculation
[23:55] <Laurence1> I run the landing spot prediction code in reverse from the desired landing spot
[23:55] <Laurence1> but for the landing spot prediction I need to form of that exponential - it could be worked out before launch but its always going to be more accurate to update the estimate as you go along
[23:58] <Laurence1> guess the lassen iq gives you z velocity so if you record the cutdown time you can find a and b from time altitude and z velocity
