+14:47 < jtanx> Hey
+17:51 < jtanx> huh
+17:51 < jtanx> it was surprisingly easy to add post support
+17:56 < sam_moore> That's cool
+17:56 < jtanx> you just fgets from stdin instead
+17:56 < jtanx> it's in the same format too
+17:56 < sam_moore> Excellent
+17:57 < jtanx> we probably do have to unescape html strings though
+17:57 < jtanx> like if someone had a comma in their password
+17:57 < sam_moore> If we had a progress report we could put "potential gaping security leak plugged"
+17:57 < jtanx> Hahaha
+17:57 < jtanx> but it still allows the get request version
+17:57 < sam_moore> Oh well
+17:57 < jtanx> but then that's your own fault
+17:57 < sam_moore> Yep
+17:59 < sam_moore> Doesn't look like the IRC channel will get a mention in the "communication" section of the report :(
+17:59 < sam_moore> Oh no wait, it does
+17:59 < sam_moore> Good
+17:59 < sam_moore> ... That "overall schedule"...
+17:59 < jtanx> Haha
+17:59 < sam_moore> I started it, and quickly realised it was a waste of time
+18:01 < sam_moore> Also, need to hate on the beaglebone less
+18:01 < sam_moore> Otherwise they might try and do something stupid like replace it next year
+18:01 < jtanx> That would be stupid
+18:01 < sam_moore> Yeah, it was a pain, but probably still one of the best things to use
+18:02 < sam_moore> RPi with dedicated ADC/DAC modules would probably have been best
+18:02 < sam_moore> Distributed system of arduinos.... noooo
+18:02 < jtanx> Yeah
+18:02 < jtanx> RPi with ADC/DAC would have been cool
+18:02 < jtanx> but only because there's more support for the RPi
+18:02 < sam_moore> Yes
+19:19 < jtanx> hmm
+19:20 < jtanx> maybe I should enable POST only for the login module?
+19:20 < jtanx> Right now, if POST and GET data is received, the GET data is discarded in place of the POST data
+19:28 < jtanx> Yeah, okay I only enabled it for login
+22:38 < jtanx> Hahahahaha
+22:39 < jtanx> I passed our code through ohloh - https://www.ohloh.net/p/MCTX3420
+22:39 < jtanx> Apparently it's work 3 years of effort, and is valued at $150k

+09:56 < sam_moore> Um... we didn't make our first commit in 200
+09:56 < sam_moore> * 2000
+09:56 < sam_moore> 10 developers???
+09:57 < sam_moore> There are 6 of us
+09:57 < sam_moore> And some people contributed about 2 lines of source code...
+09:57 < sam_moore> Mostly written in JavaScript
+09:57 < sam_moore> Really?
+09:57 < sam_moore> Is that counting the jQuery UI guff?
+09:58 < sam_moore> That's annoying, because the C part of the project is like 50% comment lines
+09:58 < sam_moore> And it says "low number of comments" based on the JavaScript :S
+09:59 < sam_moore> Still... this is really cool
+10:00 < jtanx> hahaha
+10:00 < jtanx> the 2000 commit was because we made commits on the bbb
+10:00 < sam_moore> ok...
+10:00 < jtanx> but it lacks an rtc
+10:00 < sam_moore> Where do we get the extra 4 developers from?
+10:00 < sam_moore> "Debian" is one
+10:00 < jtanx> and for some reason the time didn't get updated
+10:01 < jtanx> umm
+10:01 < jtanx> hmm
+10:01 < jtanx> Ubuntu user?
+10:01 < sam_moore> Oh, "Callum" and "Callum-" are treated seperately -_-
+10:01 < jtanx> oh
+10:01 < sam_moore> That's still only 8
+10:02 < jtanx> the results are a bit skewed
+10:02 < jtanx> because a lot of the javascript is just from other libraries
+10:02 < jtanx> well at least i think so
+10:04 < sam_moore> Yeah
+10:05 < sam_moore> Is it easy to just pass a subset of the code through?
+10:08 < jtanx> Yep - you have to set what's ignored
+10:08 < jtanx> I've just set it to ignore all *.min.js files (essentially all external js files)
+10:08 < jtanx> But it won't get updated for a while
+10:09 < jtanx> I've got to go for ~ 2 hrs

+15:10 < Callum> just finished the code to get the edge. atm it just returns the position on their object. was thinking we'd just use the timestamp and go this was the additional width at this time, additional width at time +1, so rate of change is 2*difference etc
+15:11 < Callum> also pushing 3 images to testing (actually i should go abck and push original too) but to show it blurred, after canny and with the found edge imposed over it (without w.e values i had set at the time..)
+15:15 < jtanx> Nice
+15:16 < Callum> ok merged
+15:17 < Callum> i might need some help merging this into the server code too
+15:18 < Callum> just to make sure its all good
+15:34 < jtanx> Sure
+15:34 < jtanx> I'm really busy right now though with this other crappy project that I have to do
+15:35 < jtanx> If not today, then maybe during tomorrow's meeting (if we're having a meeting then?)
+16:07 < Callum> we were meeting tomorrow? also i have an assignment due monday i havent started. was going to try and work through that and work on another project i have due..as well as this
+16:07 < Callum> still need to start my writeup for this.
+16:40 < Callum> also, if the image is completely black, the read function should return false (havent yet tested this but it should be the case)
+16:53 < Callum> also looking at justins diagram, why isnt the microscope not included?
+16:54 < Callum> or is it just both under "camera"
+17:01 < jtanx> Yeah
+17:01 < jtanx> I think it's just under "camera"
+17:02 < Callum> ok.
+17:02 < jtanx> I dunno, I thought we should try to meet some time next week
+17:02 < jtanx> monday's our usual meeting time
+17:02 < Callum> you said tomorrow though didnt you?
+17:03 < jtanx> Ohh
+17:03 < jtanx> sorry
+17:03 < jtanx> my bad
+17:03 < jtanx> I meant monday
+17:03 < Callum> was going to say, my body clock so out of wack its sunday already?
+17:03 < Callum> yea. if i can get the assignment done tomorrow il be happy to spend most oif the day trying to finish some of this off
+17:03 < jtanx> Haha mine is
+17:03 < Callum> to be fair, i normally work saturdays
+17:03 < Callum> i took it off to do work.
+17:04 < jtanx> :/
+17:04 < Callum> so it should feel like a sunday
+17:04 < jtanx> I had this assignment where I thought I had completed it, but when I reread the specs I found out that I missed a large portion of it
+17:05 < Callum> ouch
+17:05 < Callum> what assignment was this for?
+17:05 < jtanx> cits3242
+17:05 < jtanx> some programming unit
+17:05 < Callum> figured by the cits. :p
+17:05 < jtanx> hehe
+17:06 < jtanx> yeah, if it wasn't for that i'd be solely working on this project right now
+17:07 < Callum> yea iv kind of been working on 3 or 4 things all at once. and not gotten far in anything.
+17:07 < jtanx> yeah, it's always crap when things are due at the same time
+17:08 < jtanx> but 3-4 things at once? that's harsh
+17:12 < Callum> umm. assignment due tomorrow i havent started. i have anoither group project but we only really have 2 members and wev barely done anything (due friday, meant to have 4/5 members)
+17:12 < Callum> physics assignment also due on friday
+17:12 < Callum> just trying to figure out how to get it all done
+17:13 < Callum> not going to be a fun week. then after this weeks over its major catchup in the 3 units i have exams for
+17:13 < Callum> oh and this tute adrian decided to give us...should probably look at that some time too
+17:16 < Callum> whats the model for the microscope? cant find anything in dropbox
+17:22 < Callum> they are using the microscope only on the non-exploding one im assuming?
+17:23 < jtanx> Yeah
+17:23 < jtanx> the microscope
+17:23 < jtanx> it's a kaiser baas something
+17:23 < jtanx> KBA03030

+15:08 < sam_moore> Blergh, what are we going to put in the "Results" part of this report?
+15:09 < sam_moore> "We plugged it all in and it didn't explode" ?
+15:13 < sam_moore> Also it looks like gliffy only lets you export one svg on the trial account
+15:14 < sam_moore> And if the image isn't exactly A4 size, pdf is terrible
+15:14 < sam_moore> So the remainder of my figures will be png
+15:20 < sam_moore> Do we need to find references for all these things that we worked out and/or already knew ourselves...
+15:20 < jtanx> haha
+15:21 < sam_moore> I feel like referencing git commits
+15:21 < jtanx> Yeah I was going to do that
+15:21 < sam_moore> We should do that
+15:21 < jtanx> results
+15:21 < jtanx> it seems to work
+15:21 < sam_moore> ...
+15:21 < sam_moore> I put in a "Customer Satisfaction" section under results
+15:22 < jtanx> :P
+15:22 < sam_moore> It says "No matter what we did, the customer was not satisfied"
+15:22 < sam_moore> Next year they'll probably be told the beaglebone is stupid and start doing it all on an arduino
+15:22 < jtanx> mm probably
+15:22 < sam_moore> And then get told that it needs a user management system...
+15:23 < jtanx> hahahaha
+15:23 < sam_moore> I'm having trouble with what level of assumptions I should make about the reader's knowledge
+15:23 < sam_moore> Do they know what a thread is?
+15:24 < sam_moore> Do they know what "high level" and "low level" mean
+15:24 < jtanx> Thats... what I was having difficulty with too
+15:24 < sam_moore> Do they know what a kernel is?
+15:24 < jtanx> how far back do you have to explain terminology
+15:24 < sam_moore> Or context switching...
+15:24 < sam_moore> Argh
+15:24 < jtanx> write a treatise on multithreaded computing
+15:24 < sam_moore> :S
+15:24 < sam_moore> This is rather simple multithreaded stuff really
+15:26 < sam_moore> I think we need a "terminology" section
+15:27 < jtanx> THat would be good
+15:30 < jtanx> oh yeah
+15:30 < jtanx> we should be able to use commas again
+15:30 < jtanx> for that actuator step thing
+15:30 < jtanx> because it decodes the string first
+15:31 < jtanx> not sure if that will introduce any security issues though
+15:32 < sam_moore> Who cares, ship it
+15:33 < sam_moore> But I don't think so?
+15:33 < jtanx> :P
+15:33 < jtanx> maybe
+15:33 < jtanx> I dunno
+15:33 < sam_moore> sscanf can at most read to the end of the string
+15:34 < jtanx> since it decodes %hh to the hex value
+15:34 < jtanx> I mean if you give it a url encoded string
+15:34 < jtanx> with %01
+15:34 < jtanx> it would change that to the character 0x01
+15:34 < jtanx> which is like some control code
+15:34 < sam_moore> Hmm
+15:34 < jtanx> we could limit it so anything less than 0x20 is a space
+15:34 < sam_moore> Just do that then
+15:35 < jtanx> but it's probably important to url decode strings
+15:35 < jtanx> what if someone had a , in their password
+15:35 < jtanx> or weird characters
+15:35 < sam_moore> God dammit
+15:35 < sam_moore> call isprint() ?
+15:35 < jtanx> nah I mean
+15:36 < jtanx> it should be fine if we convert anything < 0x20 to a space
+15:36 < jtanx> but it's better that we're url decoding stuff
+15:36 < sam_moore> Ok
+15:36 < jtanx> because if we didn't, the password string would be like %2d instead of -
+15:36 < jtanx> for example
+15:36 < sam_moore> Yeah, that would suck
+15:37 < sam_moore> Do you think Rowan and/or James will write their parts of the report?
+15:37 < jtanx> Maybe, I dunno
+15:38 < jtanx> Rowan was trying to copy the wiki, which was written mostly by Justin?
+15:38 < sam_moore> Yeah, that's not really cool
+15:38 < jtanx> :/
+15:38 < sam_moore> I don't think there's much that can be just put into the report from the wiki anyway
+15:38 < sam_moore> It's too informal
+15:38 < sam_moore> And has a lot of "TODO: Fill this in" pages
+15:38 < jtanx> Yeah, they're counted separately anyway
+15:39 < jtanx> as in, there's a specific mark for wiki pages
+15:39 < sam_moore> Oh dear
+15:39 < jtanx> (or equivalent documentation afaik)
+15:39 < sam_moore> Every area there's a mark for is just another area they can deduct marks for not liking
+15:39 < jtanx> Yeah, I'm not liking it very much
+15:40 < sam_moore> Are we supposed to talk about the other subsystems or focus on our own?
+15:40 < jtanx> I'm hoping to focus on our own really
+15:40 < jtanx> but I guess there would be overlap
+15:48 < jtanx> did you see the microscope stuff that callum did
+16:00 < sam_moore> I glanced at it
+16:00 < sam_moore> It's in the main directory not sensors/
+16:01 < sam_moore> Does it work?
+16:01 < jtanx> well from the test pictures it looks quite good
+16:01 < jtanx> not sure how well it will work with the real thing
+16:02 < sam_moore> Hahaha
+16:02 < sam_moore> If it works with what we were given, good enough
+16:02 < jtanx> Yep
+16:03 < sam_moore> We seem to end up having to actually implement all of sensors things
+16:03 < sam_moore> I guess I will add the calibration in at some point before Tuesday
+16:04 < jtanx> :/
+16:04 < sam_moore> It shouldn't be that hard, I've done it before
+16:04 < sam_moore> Convert raw value to nearest two indexes in an array
+16:04 < sam_moore> Interpolate between those two indexes
+16:05 < sam_moore> I think for the Microphone there's 1024 points because he tested it with a 10 bit ADC somehow
+16:05 < sam_moore> For other things...
+16:05 < sam_moore> There are 10 points
+16:05 < jtanx> 1024 points
+16:05 < jtanx> wait what
+16:06 < sam_moore> 1 point per ADC value
+16:06 < sam_moore> As in, I was sent a lookup table of ADC value -> dB level
+16:06 < jtanx> oh right
+16:06 < jtanx> yeah
+16:06 < jtanx> he was testing it on an arduino
+16:06 < jtanx> was the arduino calibrated properly
+16:07 < sam_moore> Lalala not listening...
+16:07 < jtanx> :P
+16:07 < sam_moore> Oh, it loks like I only have 20 points anyway
+16:09 < sam_moore> This calibration does assume that electronics uses exactly the same voltage divider that sensors guy used
+16:09 < jtanx> it's probably close enough
+16:09 < sam_moore> Well maybe
+16:09 < sam_moore> Just trusting the data sheet is probably close enough
+16:10 < sam_moore> I'm not sure I see the point in calibrating a device if you don't actually use the final setup to calibrate it...
+16:10 < jtanx> Yeah, true
+16:22 < sam_moore> Is the use of '*' in pointer names a "standard"... I always thought it was... how you made a variable a pointer
+16:22 < jtanx> Oh yeah that
+16:31 < sam_moore> God dammit I have no motivation left to do anything
+16:32 < jtanx> urgh
+16:32 -!- jtanx changed the topic of #mctxuwa_softdev to: :(
+16:34 < sam_moore> Should I put your part of the report into tex?
+16:34 < jtanx> Yeah, I guess
+16:34 < sam_moore> I think if I put your part and Justin's part combined with my hopelessly incomplete part...
+16:34 < sam_moore> we will actually have too many pages
+16:34 < jtanx> :/
+16:34 < jtanx> was there a hard limit?
+16:35 < jtanx> I probably need to cut down my section, too much rambling
+16:36 < sam_moore> I think it's fine
+16:37 < jtanx> I dunno
+16:37 < jtanx> I have the feeling I'm not following the guidelines correctly on what I'm supposed to talk about
+16:37 < sam_moore> We can't win either way
+16:37 < jtanx> Yeah, like where am I meant to find the references for half the stuff I did
+16:38 < sam_moore> Surely James Trevelyn would have got a few papers out of his Telelabs thing?
+16:39 < sam_moore> I'll leave it for now
+16:39 < jtanx> Okay
+16:41 < sam_moore> My section will be great when I actually include all those figures I refer to...
