apparently some are 4mA some are 6mA and the thing needs 5mA +19:47 < sam_moore> I don't know? Try every single pin, actually measure the current drawn by the relay switch +19:47 < sam_moore> Replace the transistors on the relay +19:47 < jtanx> haha +19:47 < jtanx> that sounds so dodge +19:47 < sam_moore> We tried 2 GPIO pins at once :S +19:47 < jtanx> in parallel? +19:47 < sam_moore> Didn't work +19:48 < sam_moore> Yeah +19:48 < jtanx> hahaha +19:48 < sam_moore> But I think that might cause one to draw current from the other +19:48 < jtanx> hmm +19:49 < sam_moore> Need to actually look at the GPIO circuit diagram to work out what that would do +19:49 < sam_moore> Our software can sample more than fast enough for the microphone +19:50 < jtanx> that's cool +19:50 < jtanx> could you see it on the graph +19:50 < sam_moore> But plotting it in flot crashes the browser +19:50 < sam_moore> Sort of +19:50 < sam_moore> Had to change start_time to get all the points +19:51 < jtanx> Flot doesn't sound too reliable +19:51 < sam_moore> It crashes after ~1s +19:51 < sam_moore> min +19:51 < sam_moore> not second +19:51 < jtanx> But can we just cut down on the number of data points +19:51 < jtanx> how many datapoints is that after 1 min +19:51 < sam_moore> It's obviously incredibly inefficient +19:52 < sam_moore> I will see if averaging points helps flot +19:52 < sam_moore> Or if it's actually JavaScript not liking really big arrays +19:52 < jtanx> yeah +19:52 < jtanx> I think having large arrays consumes an enormous amount of memory in js, for some reason +19:53 < sam_moore> Dammit +19:54 < sam_moore> We could make a python GUI using requests and pyplot :P +19:54 < jtanx> -.- +19:54 < jtanx> wouldn't it be worse, trying to plot it on the beaglebone +19:55 < jtanx> given that you're using a full blown computer to plot it +19:55 < sam_moore> No, you still plot it on the client +19:55 < jtanx> How does that work +19:56 < jtanx> You'd have to render it on the BBB, no? +19:56 < sam_moore> Nope; get data the same way through HTTP and plot on the client +19:56 < jtanx> what's the difference? +19:57 < sam_moore> The BBB doesn't gave a problem transferring data points +19:58 < sam_moore> The browser ie JavaScript sucks at coping with them +19:58 < jtanx> Yeah, but if you say plot on the client, how do you plot on the client? +19:58 < jtanx> ohhhhhhh +19:58 < jtanx> Right I understand now +19:59 < sam_moore> Python has modules for plotting +19:59 < sam_moore> And modules for HTTP requests +19:59 < jtanx> You're saying instead of a web interface a python gui instead +19:59 < sam_moore> Maybe +19:59 < jtanx> ?? +19:59 < sam_moore> I can at least do a proof of concept +19:59 < jtanx> I'm lost +20:00 < sam_moore> But we probably shouldn't redesign the entire GUI... +20:00 < jtanx> Hey, I'm all for it if it can be done +20:20 < jtanx> Now, to do this control page +20:20 < jtanx> A username can only contain alphanumeric characters +20:21 < jtanx> right? +20:21 < sam_moore> Yep +20:21 < jtanx> okay +20:21 < jtanx> was just thinking if someone had say .. in their username... +20:25 < sam_moore> You can allow other characters +20:25 < jtanx> well as in +20:25 < sam_moore> Not '=' though +20:25 < jtanx> having .. in their username would move you up a directory +20:26 < sam_moore> Ah, cunning +20:26 < sam_moore> Thwarted by general paranoia though +20:26 < jtanx> :P +20:26 < sam_moore> No stupid characters in usernames +20:27 < sam_moore> Definitely no '/' allowed +20:27 < jtanx> hahaha +20:27 < jtanx> I think an alphanumeric limitation is good +20:27 < jtanx> until the university stipulates having random characters in usernames +20:28 < sam_moore> You forget that if the university does that they will have to cope with the same kind of bullshit +20:29 < jtanx> Yeah, true that +21:42 < sam_moore> I pushed a python plotting thing, but I don't really think we should be switching to it at this stage. +21:42 < jtanx> Okay +21:42 < sam_moore> I'll try tweak the flot GUI tomorrow to make it less shit +21:43 < jtanx> hahaha +21:58 < jtanx> urgh +21:58 < jtanx> barely started on the control page +21:59 < jtanx> I guess I'll have to complete it tomorrow +21:59 < jtanx> even though we're probably (maybe) going with james gui +22:00 < jtanx> I've removed the width restriction +22:00 < jtanx> and you can hide the navigation bar +22:00 < jtanx> for more space +22:11 -!- jtanx [~asfa@220-253-133-241.dyn.iinet.net.au] has quit ["ChatZilla 0.9.90.1 [Firefox 24.0/20130910160258]"] +--- Day changed Sat Oct 19 2013 +07:59 -!- jtanx [~asfa@220-253-133-241.dyn.iinet.net.au] has joined #mctxuwa_softdev +10:39 < jtanx> blegh, now to start on the js for the control page +11:10 < jtanx> what would you say if instead of all this chdir business +11:10 < jtanx> one of the initial options to start the software is to specify where you want experiments to be held +11:11 < jtanx> e.g /usr/share/experiments or whatever +11:11 < jtanx> then you build the path based on the username +11:25 < sam_moore> That sounds good +11:26 < jtanx> Okay, I'll try to do that then +14:37 < sam_moore> There's some kind of error in mctx.gui.js now +14:37 < jtanx> what's happening?

I think what I originally had was runBeforeLoad.always() calling $("#graph-controls").setDevices +14:55 < sam_moore> Possibly inside a document.ready +14:55 < sam_moore> But now mctx.gui.js is calling document.ready itself... +14:55 < jtanx> waiit +14:55 < jtanx> I think it's ok now +14:56 < jtanx> it was just brackets +14:56 < jtanx> I'll try it on my server first +14:58 < jtanx> yeah, I see what you mean +15:01 < jtanx> ahh +15:01 < sam_moore> Well I fixed it enough to test stuff +15:01 < jtanx> yeah +15:02 < jtanx> you planning on modifying stuff? +15:02 < sam_moore> I think it's just a matter of having runBeforeLoad().done() call $(document).ready() and then initialise stuff +15:02 < jtanx> I'll just keep it in my repo for now +15:03 < sam_moore> With runBeforeLoad.fail if you want to handle bad stuff +15:03 < jtanx> I just made it +15:03 < jtanx> runBeforeLoad().always(function() { +15:03 < jtanx> $(document).ready(function() { +15:03 < jtanx> $("#graph-controls").setDevices(); +15:03 < jtanx> }); +15:03 < jtanx> }); +15:03 < sam_moore> Yep, that's what I just did +15:03 < sam_moore> You can commit it and I'll pull it +15:03 < jtanx> okay +15:03 < sam_moore> If you fix the console and the errorlog things as well +15:03 < jtanx> yep +15:03 < jtanx> pushed that too +15:05 < sam_moore> Hmm, start_time = -1 is not actually giving the most recent second of data +15:05 < sam_moore> That might be a server API problem +15:05 < jtanx> hmmm +15:05 < sam_moore> But it might also explain why things were shitting themselves so much with the fast sampling rate +15:06 < jtanx> what is it giving? +15:06 < sam_moore> Because the jQuery would be getting hundreds of thousands of points... +15:07 < sam_moore> At the moment the server API is not giving any points and giving back a stupid value for start_time +15:07 < sam_moore> I think I might have broken it when I changed all the clocks +15:07 < jtanx> when did you change ti? +15:07 < sam_moore> Just now +15:07 < jtanx> ah +15:07 < sam_moore> I'm hoping that my first assumption about the thousands of points was the case before I broke it as well :P +15:08 < sam_moore> (ie: It was already broken before I broke it more) +15:08 < jtanx> ahahahah +15:08 < jtanx> I can try +15:08 < jtanx> I still have the old version +15:09 < jtanx> with start_time=-1 it returns nothing +15:09 < jtanx> start_time in the response is constant +15:11 < sam_moore> Yeah I get wierd stuff +15:11 < sam_moore> start_time = 17889.590701 +15:12 < sam_moore> "current_time" : 18589.539255 +15:12 < jtanx> is that with clock_gettime?
