 21:20 < jtanx> :P
 21:20 < jtanx> the computer vision unit sounds interesting, but a lot of maths/theory involved

+11:02 < sam_moore> I'm really glad I put the IRC logs under git
+11:02 < sam_moore> It's very helpful for keeping my diary up to date
+11:40 < jtanx> hehe
+11:40 < jtanx> I'm gladful for git
+11:48 < jtanx> about the bbb
+11:48 < jtanx> it's probably best to just install debian to the internal memory
+11:54 < jtanx> on the controls
+11:54 < jtanx> maybe we can have the following states: start/pause/resume/stop/close
+11:56 < jtanx> actually, maybe just start/pause/resume/close
+11:56 < jtanx> when an 'emergency stop' due to the sanity checks occurs
+11:57 < jtanx> actually, start/pause/resume/close/emergency
+11:57 < jtanx> start/pause/resume/close can only be initiated by the client
+11:58 < jtanx> emergency can be initiated by client/server
+11:58 < jtanx> in emergency, actuators are set as necessary then deactivated
+11:58 < jtanx> but importantly, the data files remain open, which hopefully removes the need for mutexes
+12:26 < sam_moore> That seems sensible
+13:20 < sam_moore> Hey
+13:20 < sam_moore> It's actually quite simple to stream an image through FastCGI
+13:21 < jtanx> yeah
+13:21 < jtanx> you just fwrite the image buffer
+13:21 < sam_moore> Yep
+13:21 < jtanx> I had some test code for that but could never test it
+13:22 < jtanx> no webcam
+13:22 < sam_moore> Ah, damn
+13:22 < sam_moore> I've written some code, it works pretty brilliantly
+13:22 < jtanx> nice
+13:22 < jtanx> this control code is really annoying me
+13:23 < jtanx> just all the considerations of if you need a mutex here or not and 'what happens if...'
+13:23 < sam_moore> Ah, sorry to hear that
+13:23 < jtanx> yeah nah its ok
+13:24 < jtanx> but that interferometer stuff you did looks really cool
+13:26 < sam_moore> Yeah, it worked surprisingly well
+13:26 < sam_moore> It can cope with a fair bit of background light, even without all the improvements I was thinking about
+13:27 < sam_moore> If I add 2 or 3 more columns to scan, and use the fact that we actually know the spatial frequency to eliminate nodes that are too close together
+13:27 < sam_moore> It should be pretty good
+13:27 < sam_moore> I'm not sure what the laser intensity will be, but the generated image looks similar to ones you can find on the internet
+13:28 < sam_moore> One possible problem is if the mirrors aren't flat enough
+13:28 < sam_moore> But hopefully it won't be a big issue (since they've pretty much just specified an expensive pre-built kit which presumably has flat mirrors)
+13:29 < jtanx> yeah
+13:30 < jtanx> here's to hoping 'it just works'
+13:30 < sam_moore> Yep :P
+13:31 < sam_moore> Got to go, bye
+13:32 < jtanx> ok cya
