I don't know. But the guy seemed relieved anyway. +15:59 < Callum> and was gonna ask if you remembered anything about the pi meson decay question for physics (how do you get the anti-neutrinos momentum, or do you assume it to be 0 as well? but then it doesnt really make sense with conservation of momentum) +16:00 < sam_moore> Woah, I don't remember the assignments in that much detail +16:00 < Callum> was hoping you would :p +16:00 < sam_moore> No, I just have vague memories of algebra +16:01 < sam_moore> And looking through notes +16:01 < Callum> hmm. i cant seem to find anything in the notes +16:01 < Callum> because he says to assume the rest mass of the anti-neutrino is 0 +16:02 < Callum> and i don't really remember much in regards to energies and 0 rest mass ;/ +16:02 < jtanx> I talked to someone who did computer vision before +16:02 < jtanx> and he's really doubtful that you can get accurate readings off a webcam +16:02 < sam_moore> Callum: I don't think you can assume the momentum is zero, other than that, I don't have much to offer +16:02 < Callum> the question also says to have it in terms of m(pi) m(e) and c +16:03 < Callum> and yea thats what i thought. it doesnt make sense to do that. just cant remember how to do it D; +16:03 < Callum> @jeremy yea well, its a pain but possible +16:04 < Callum> really comes down to how good your camera is/sampling rate/how quickly you can process it. +16:04 < sam_moore> How about you do some experimenting with a webcam and see what you can do with it? +16:04 < Callum> but you can get some pretty good webcams nowadays (but then again the better it is the longer it takes to process) +16:04 < jtanx> personally, I don't think it will work +16:04 < sam_moore> It looks like we might just end up streaming images diretly to a website +16:04 < Callum> i don't have any +16:04 < Callum> yea well even if thats all we do we still need the camera +16:05 < Callum> spose i could use my laptop one but i doubt that would be very good +16:05 < Callum> could run it through the canny algorithm and see what it produces +16:06 < sam_moore> Sounds like an idea +16:07 < sam_moore> A good idea specifically +16:07 < jtanx> about the sensorhandler +16:07 < sam_moore> Yes? +16:07 < jtanx> do you envision leaving it in fastcgi.c permanently +16:07 < jtanx> or for that matter any other handlers +16:07 < sam_moore> I was kind of thinking there would be a "handlers.h" and "handlers.c" +16:08 < sam_moore> Just to make things more organised +16:08 < jtanx> yeah +16:08 < jtanx> I'm trying to export enough of the functionality +16:08 < jtanx> to do that +16:08 < jtanx> but the json thing is annoying +16:08 < jtanx> especially when you need to spit out arrays +16:09 < jtanx> unless you have something like FCGI_Printf +16:09 < jtanx> and it's up to you to format it correctly +16:09 < Callum> bloody physics lecture video is laggy. gonna have to download it and hope for the best. fuck echo +16:10 < jtanx> compared to lectopia you get 2x filesize with no visible benefit in quality +16:10 < Callum> they're both shit. +16:10 < sam_moore> You could have seperate "BuildJSON_Key" and "BuildJSON_Value" functions, with a "BuildJSON_ValueArray" maybe +16:10 < Callum> haha +16:11 < sam_moore> FCGI_Printf is Ok though, it's not too much formating +16:11 < jtanx> the problem with the buildjson_* stuff +16:11 < jtanx> is it gets very verbose +16:12 < jtanx> and you can probably come up witha situation that breaks it too +16:12 < jtanx> and don't get me started on value types +16:12 < sam_moore> Haha +16:14 < sam_moore> We can always just send plain text and make James turn it into JSON :P +16:14 < jtanx> ahaha +16:14 < jtanx> yeah that could work +16:15 < jtanx> mm +16:15 < jtanx> this is where java is good +16:15 < jtanx> or any other higher level language +16:21 < jtanx> ok so it's a bit of both, but how about: FCGI_JSONKey(key) and FCGI_JSONValue(format, ...) +16:22 < sam_moore> That looks good +16:25 < jtanx> I'm also adding long/double types for the BuildJSON function, just for convenience +16:25 < jtanx> any preference to naming conventions? +16:26 < jtanx> FCGI_BuildJSONLong +16:27 < sam_moore> Seems OK +16:28 < sam_moore> I need to go do some ENSC1001 stuff (hooray) +16:29 < jtanx> yuck +16:30 < Callum> hhaha +16:30 < Callum> have fun :p +16:30 < Callum> although i cant really talk. about a days worth of physics and a days worth of ensc3016 shit i should get through, on top of mctx and geng4402 stuff. yay for being behind already +16:38 < Callum> well iv got an answer for the first part (second part should be the same process). just hope its right :s +16:46 < jtanx> ok, time to merge this into the server code +19:47 < jtanx> hmm interesting - it crashes if compiled with clang but not with gcc +19:49 < jtanx> probably just a bug in clang 3.2 +20:08 < jtanx> ok, just submitted a pull request to update the fastcgi stuff +20:08 < jtanx> for now I moved Sensor_Handler to sensor.c +20:09 < jtanx> the status codes have all changed +20:09 < jtanx> If you absolutely cannot process anything given the input arguments, you call FCGI_RejectJSON +20:10 < jtanx> If you fail for some other reason (e.g unauthorized access), you use FCGI_BeginJSON with the appropriate status code +20:10 < jtanx> With RejectJSON, it sends a HTTP 400 code so any query through AJAX/jQuery will fail with no extra info +20:11 < jtanx> With BeginJSON, the HTTP code is always 200 OK, so you are able to transmit extra info if it failed for another reason +20:12 < jtanx> BeginJSON will automatically add the module handler name + the status code +21:47 -!- jtanx [~asfa@124-169-120-181.dyn.iinet.net.au] has quit ["ChatZilla 0.9.89 [Firefox 23.0.1/20130814063812]"] +--- Day changed Wed Aug 21 2013 +00:53 -!- Callum [~chatzilla@124-171-171-92.dyn.iinet.net.au] has quit [EOF From client]
