+19:11 < jtanx> lol
+19:11 < jtanx> the camera that we were using for the soldering lab inserted a bunch of wavy lines/static into the video
+19:12 < sam_moore> It's an effect
+19:14 < jtanx> nah
+19:14 < jtanx> the camera was actually broken
+19:15 < sam_moore> (I figured that)
+19:15 < sam_moore> You could pretend it's supposed to be an 80s style video?
+19:15 < jtanx> yeah that could work
+19:16 < jtanx> have you done it yet?
+19:18 < sam_moore> No :S
+19:20 < jtanx> well
+19:21 < jtanx> according to the manual, you need to connect a wire from R5 on the sensor board to the relay board
+19:21 < jtanx> problem was we already chopped off the lead on R5
+19:22 < jtanx> another group connected the wire to the LEd though
+19:22 < jtanx> seemed to work
+20:02 < jtanx> so are we using clock_gettime?
+20:08 < sam_moore> I think so, we can use CLOCK_MONOTONIC_RAW if we are paranoid about the system time getting changed
+20:08 < sam_moore> Or we can just use CLOCK_REALTIME if we aren't
+20:09 < jtanx> I thought CLOCK_MONOTONIC was supposed to be best, because the RAW version wasn't compensated for temp/other stuff
+20:10 < jtanx> http://stackoverflow.com/questions/3523442/difference-between-clock-realtime-and-clock-monotonic
+20:10 < jtanx> about the FCGI loop blocking
+20:10 < jtanx> you can switch to FCGX_ methods
+20:10 < jtanx> I think
+20:11 < jtanx> but is it really necessary
+20:20 < jtanx> about the valgrind comment in sensors.c
+20:20 < jtanx> this is probably it: http://stackoverflow.com/questions/5844242/valgrind-yells-about-an-uninitialised-bytes
+20:23 < sam_moore> It's probably not necessary to stop the FCGI loop blocking, don't worry about it
+20:25 < sam_moore> Yeah, I didn't initialise the buffers anywhere
+20:25 < jtanx> actually I can't reproduce that message
+20:25 < sam_moore> Hmm
+20:26 < jtanx> about the sensor times
+20:27 < jtanx> what about if you all reference it relative to some point
+20:27 < jtanx> eg
+20:27 < sam_moore> The epoch :P
+20:27 < jtanx> lol
+20:27 < jtanx> I mean
+20:28 < jtanx> when you get sensor data, you store the difference in time between the start of recording and now
+20:28 < sam_moore> Sure, that makes more sense
+20:29 < sam_moore> Just give the client the start of recording time and they can convert it to a time of day / day in the calendar themselves
+20:30 < jtanx> yeah
+20:30 < jtanx> you could have a specific request to return the starting time
+20:30 < jtanx> then it's implicit for all requests
+20:30 < jtanx> btw I submitted a pull request for the nginx configs
+20:32 < sam_moore> Ok
+20:32 < sam_moore> I've added you to collaborators so you can merge them yourself if you need to

+16:31 < jtanx> huh
+16:31 < jtanx> firefox's javascript debugger is pretty cool
+16:31 < sam_moore> Firebug? Yeah
+16:35 < jtanx> nah the inbuilt one
+16:35 < jtanx> firebug's good for inspecting html though
+16:35 < jtanx> haven't used firebugs js debugger yet
+16:35 < sam_moore> Oh, I didn't know they had an inbuilt one
+16:36 < jtanx> Ctrl+Shift+K
+16:36 < sam_moore> Of course I normally use Iceweasel, which is currently built as firefox 10.0.2 with a different name
+16:36 < jtanx> well that's about 10 releases behind
+16:36 < sam_moore> That looks pretty similar to firebug anyway
+16:55 < jtanx> inline conditionals in javascript are whack
+16:55 < sam_moore> I haven't done much javascript, but a lot of it does seem whack
+16:56 < sam_moore> jtanx: What are you working on in JavaScript?
+16:56 < jtanx> unit tests
+16:57 < sam_moore> Cool
+17:01 -!- Callum_ is now known as Callum
+17:18 < jtanx> javascript in general is annoying me though
+17:25 < Callum> when exactly is this soldering lab due? fucking thing.
+17:27 < jtanx> next friday
+17:27 < Callum> it says week 5 on lms
+17:27 < jtanx> sept 6
+17:27 < Callum> where's it say this?
+17:27 < jtanx> yeah he made an announcement
+17:27 < jtanx> that it's wrong
+17:27 < jtanx> somewhere
+17:28 < Callum> sigh. this unit..i swear
+17:28 < Callum> if it really is next week then i'd be so relieved
+17:28 < Callum> wow
+17:28 < Callum> he made an announcement today..
+17:28 < Callum> wait yesterday
+17:29 < jtanx> still got that central plant fbd to do
+17:29 < Callum> why hasnt LMS emailed me a notification? (/end spam)
+17:29 < Callum> yea i know
+17:29 < Callum> which i think i have it pretty much done
+17:29 < Callum> not 100% sure on it though
+17:29 < Callum> and whether to add pumps and shit into it
+17:29 < jtanx> what did you have on it?
+17:30 < Callum> HA as i say that i check my phone and i have the message about the announcement
+17:30 < jtanx> and what did you call the chiller things?
+17:30 < Callum> pretty much just the 4 chillers, a line showing it can go back (they're literally called chillers ahha(
+17:31 < Callum> then i had another part to show the chillers (evaporation/condensor/compressor and cooling tower is connected to condenser)
+17:31 < jtanx> ook
+17:31 < Callum> however
+17:32 < Callum> im not sure about the input/output of the chiller
+17:32 < Callum> because stuff online shows it to be the evaporator
+17:32 < Callum> but isnt it water being pumped?
+17:32 < jtanx> I think there were pumps on the output
+17:33 < jtanx> were there three outputs?
+17:33 < Callum> also not sure if i should/wherte to add the tank (yea ofc theres pumps but not sure to put them in to the diagram, pretty much everything is pumped)
+17:33 < Callum> outputs where?
+17:33 < jtanx> North/Sout/East distribution things
+17:33 < jtanx> iirc
+17:33 < jtanx> yeah not sure whether to add tank or not
+17:34 < Callum> oh that, i didnt bother with that
+17:34 < Callum> just how did the chiller connect with the rest of the plant?
+17:34 < Callum> was the evaporator the input/output?
+17:34 < Callum> because the chiller feeds out to the water tower and the tower feeds back into the chiller (i think)
+17:36 < Callum> also what was the thing called? that allowed water to flow back and forth bypassing the chillers. back something?
+17:36 < Callum> really they should have told us before we went in we had to do this. some lazy fucks like me dont read the outline so i didnt take notes..or try to commit stuff to memory :po
+17:39 < jtanx> the bypass?
+17:39 < jtanx> I haven't gone into detail
+17:39 < jtanx> so I just have chiller
+17:39 < jtanx> and cooling tower
+17:39 < jtanx> maybe I should
+17:40 < Callum> remember how tehre was 4 chillers, and they would only run what was needed.
+17:40 < jtanx> yeah
+17:40 < jtanx> how many cooling towers?
+17:40 < Callum> and if they had more than they needed there was a pipe to flow back, or if they had some chilled water from the tanks or w.e it bypassed chillers
+17:40 < Callum> i dont know, but im not sure how to show it all
+17:40 < Callum> im sure what iv got is somewhat decent
+17:41 < jtanx> I used visio and I ended up spending so much time trying to get the lines rihgt
+17:41 < jtanx> probably would have been faster to hand draw it
+17:41 < jtanx> still not finished too
+17:41 < Callum> haha im fiarly sure i read somewhere it was hand drawn :p
+17:41 < jtanx> meh I suck at drawing
+17:42 < Callum> maybe not. "This is to be drawn and annotated on single A4 page"
+17:42 < Callum> i dont think they'll be picky
+17:42 < jtanx> and there's lines everywhere
+17:42 < Callum> really? how do you have lines everywhere?
+17:42 < jtanx> ok so chiller
+17:42 < Callum> it's a fairly simple system. unless i'v done it wrong :s
+17:43 < jtanx> has warm chilled water (1), chilled coolant (2), hot coolant (3), chilled chilled water(4), control line (5), (maybe) sensor back to controller (6)
+17:43 < jtanx> that's ~5 lines in/out of one box?
+17:44 < Callum> hmm. havent included coolant or control/sensor
+17:44 < Callum> maybe i should :S
+17:44 < jtanx> and an operator
+17:44 < jtanx> to the controller
+17:45 < Callum> thing is it asked for a high level FBD though
+17:45 < Callum> which means not very detailed
+17:45 < Callum> or maybe it didnt?
+17:45 < jtanx> yeah, so do you need to show condensor/evaporator
+17:45 < jtanx> I just have a chiller box
+17:46 < jtanx> anyway... afk ~10 mins
+17:46 < Callum> the condensor/evaporater is part of the chiller isnt it?
+17:46 < Callum> ok
+18:10 < Callum> anyone finished reading chapter 4 of the notes?
+18:11 < jtanx> what's that
+18:11 < Callum> sensors
+18:12 < Callum> so dull :l
+18:12 < Callum> and pretty much no chance to remember enough of it. quiz tomorrow is going to be fun..
+18:12 < jtanx> oh
+18:13 < jtanx> shit
+18:13 < jtanx> have to study for that
+18:13 < Callum> rofl
+18:14 < jtanx> :/
+18:15 < Callum> gonna just have to wing most of them again like last time most likely.
+18:15 < jtanx> probably
+18:15 < jtanx> Well, the unit testing thing works http://mctx.us.to:8080/unit-tests/
+18:15 < jtanx> now what unit tests should there be
+18:18 < Callum> not sure.
+18:25 < Callum> brilliant! the notes show a false colour image built from a black and white image...while printed in black and white.
+18:34 < jtanx> :P
+19:50 < jtanx> um
+19:50 < jtanx> did we get around to doing the sparkplus thing
+19:54 < jtanx> we need to do it before the end of the week
+19:54 < Callum> umm.
+19:54 < Callum> actually justin already set up the group
+19:54 < Callum> so you need to hurry up and join before we have to recreate the group :P
+19:54 < jtanx> nah it expired
+19:54 < Callum> wait already?
+19:54 < Callum> zzz
+19:55 < jtanx> 5 hr deadline
+19:55 < Callum> and adrian said it was 24Hr, whats with this 5 hour shit

+14:25 < james__> Hey Jeremy. Is there a way to find my login hash key if i am already logged into the api?
+14:28 < jtanx> um
+14:28 < jtanx> right now you should store it
+14:29 < jtanx> just declare a global variable and set it to the hash
+14:30 < jtanx> or if you have made a class
+14:30 < jtanx> just make it an element
+14:31 < james__> I'm still logged in from ages ago and i can't logout so i can get a different key that works
+14:31 < jtanx> that
+14:31 < jtanx> ok
+14:31 < james__> Possibly a bug that needs fixing?
+14:31 < jtanx> so the way it works right now is there's a 3 minute timeout on the key
+14:31 < jtanx> no
+14:31 < jtanx> there's actually two layers
+14:32 < jtanx> the password that you enter first (mctxadmin) is what's called HTTP basic authentication
+14:32 < jtanx> this lets you gain access to /api/login
+14:32 < james__> Well i tried loging in again and its saying i am already logged in
+14:32 < jtanx> when you reach /api/login you get the access key
+14:32 < jtanx> there's a three minute timeout on the key
+14:32 < jtanx> if you wish to invalidate the key
+14:33 < jtanx> you call
+14:33 < jtanx> /api/login?end
+14:34 < jtanx> you can force getting a key by also calling /api/login?force
+14:34 < james__> right. well it worked this time
+14:34 < james__> Thats weird
+14:34 < jtanx> so the only thing that the key prevents is stopping accidental concurrent use
+14:34 < james__> Fair enough
+14:35 < jtanx> Calling /api/login?force will force a new key to be generated and the old one to be invalidated
+14:35 < james__> Okay
+14:35 < jtanx> btw as I was working on unit testing
+14:35 < jtanx> I did a function to retrieve the json data
+14:36 < jtanx> http://mctx.us.to:8080/unit-tests/unit-tests.js
+14:37 < james__> I will have a look. I have some buttons working and stuff. Working on putting them in a seperate script file for easier editing etc
+14:37 < james__> They don't seem to be playing nice at the moment
+14:37 < jtanx> ok
+14:38 < jtanx> how come it takes so much effort to get some buttons working
+14:39 < james__> Getting the css to mesh with the js
+14:40 < james__> I have buttons fine
+14:40 < james__> And they work
+14:40 < jtanx> maybe you should get the functionality to work first
+14:40 < jtanx> with the ajax queries
+14:40 < jtanx> before worrying about styling them
+14:40 < james__> I have the functionality pretty much working
+14:41 < jtanx> so the querying works?
+14:41 < james__> But i want the styling to work before we scale it up
+14:41 < james__> That way its less hassle to fix it later
+14:41 < jtanx> could you post it to git?
+14:41 < jtanx> it'd be cool to have a look
+14:45 < james__> The way i am thinking about having it set out is having a central index.html which just imports all the js. The js will contain all the functionlity seperated in to similar functions. Ie. all the buttons in one script
+14:46 < jtanx> right
+14:46 < james__> That should allow for ease of scaling and editing
+14:46 < james__> Also changing id's and stuff

+17:06 < jtanx> say you want to perform a command
+17:06 < jtanx> eg move an actuator
+17:07 < jtanx> and suppose checks have to be made against other sensors to ensure that this command is good to go
+17:07 < jtanx> how are those checks going to be made?
+18:10 < sam_moore> The Actuator Handler will call some sanity check against the most recent sensor data
+18:11 < sam_moore> If they aren't, it will respond with some appropriate JSON or HTTP status code
+18:11 < sam_moore> eg: "Try again later when the pressure is in the right range", or "Don't do that you silly person"
+18:15 < jtanx> ._.
+18:21 < jtanx> I wonder if there's a way to pull from your git repository without creating the 'merge branch master from...' commits
+18:22 < sam_moore> I don't think so
+18:22 < jtanx> I tried playing with rebasing but it doesn't work out so well
+18:40 < jtanx> ok so I've committed some stuff to my repository that changes the handling of controls/actuators/login
+18:41 < jtanx> I'm not sure if it's the best way to do it
+18:41 < jtanx> though
+18:41 < jtanx> What I did was get rid of /api/login
+18:41 < jtanx> and instead have /api/control
+18:41 < jtanx> All of the control code (eg actuators but may be other controls? Start/stop the whole thing?) has been moved to controls.c
+18:42 < jtanx> You still need to supply username and password to access /api/control
+18:42 < jtanx> and what was previously called the 'authorization key' is now the control key (ie who has control)
+19:00 < sam_moore> Ok, I'll take a look at it later
+19:01 < sam_moore> Don't worry about the merge messages, it's not a big deal
+19:06 < jtanx> ok thanks

+14:19 < Callum> gah havent done much for this project this week. not sure what i should do either
+14:19 < jtanx> hmm
+14:19 < Callum> so far behind in one of my units too. haha joys of uni
+14:19 < jtanx> lol
+14:20 < jtanx> werent we meant to get the camera stuff working or something
+14:21 < Callum> well yea but thats more rosher getting stuff working on his end. still not really sure what's going on. need to find an efficient way to transfer data (which would be directly streaming but it seemed adrian wanted some sort of processing)
+14:21 < Callum> guess i could start working on edge detection
+14:21 < jtanx> james hasn't got much done afaik
+14:21 < Callum> nah dont think he ahs
+14:22 < jtanx> but man I was looking at the javascript stuff
+14:22 < jtanx> and it's really annoying
+14:22 < jtanx> everything in javascript is asynchronous
+14:22 < jtanx> so you have a callback for an AJAX query, and it gets executed some time in the future
+14:23 < jtanx> it's really hard to pass variables to the callback and then also retrieve them
+14:23 < Callum> hmm
+14:23 < jtanx> i'm probably not doing it in the right fashion or something
+14:28 < Callum> not sure. don't really understand this stuff myself. havent done much/any
+14:45 < jtanx> flask is so cool
+15:01 < jtanx> oh
+15:02 < jtanx> maybe we can use cookies to store authorization
+15:02 < jtanx> instead of in javascript

+16:00 < sam_moore> I'm not sure what James has done, but there's nothing under git
+16:02 < sam_moore> http://www.flotcharts.org/flot/examples/ajax/index.html is a good starting point for updating sensor graphs
+16:03 < sam_moore> jtanx: I wouldn't worry about the login/authentication too much for this week
+16:04 < jtanx> james said he got the buttons working but that's about it
+16:04 < jtanx> he's more concerned about issues with styling them than getting a fully fledged gui
+16:04 < sam_moore> I think actually having a gui is more important than having a pretty gui
+16:04 < sam_moore> At the moment anyway
+16:05 < jtanx> yeah
+16:05 < jtanx> it would be great to have *something*
+16:05 < jtanx> the problem with js
+16:05 < jtanx> is from what i've seen, the callback occurs in the jQuery file
+16:06 < jtanx> so you can't set global variables in say sensors.js
+16:06 < jtanx> and expect to be able to read/set them in the callback
+16:06 < sam_moore> Hmm, that's wierd
+16:06 < jtanx> what really shits me about javascript is variable handling
+16:06 < sam_moore> Hang on, let me have another look at the only project I ever used jQuery for... :P
+16:07 < jtanx> you can pass one/none/more than specified parameters
+16:07 < sam_moore> It was a chess game, so it should definietly be possible to modify variables in the callback function
+16:07 < jtanx> yeah there's probably a way, I just don't know it
+16:08 < jtanx> about the actuators
+16:08 < jtanx> I've already got something working in my repository
+16:08 < jtanx> but I don't really like how I've done it
+16:30 < sam_moore> I'm making a minimal gui (it will be able to plot something, and have a button); we can either ditch it or improve on it later
+16:31 < jtanx> sounds good
+16:35 < sam_moore> Callum: If you want to make a (really awful but possibly looking good enough at this stage for Adrian) "streaming" images thing
+16:35 < sam_moore> You can have your program continuously save to a file
+16:35 < sam_moore> And a html page that just has "<meta http-equiv="refresh" content="0">" in the header
+16:35 < sam_moore> With a link to the image
+16:36 < Callum> alright il look into it
+16:36 < sam_moore> It's absolutely aweful, but it will give the effect of a really laggy video
+16:36 < jtanx> nice :P
+16:36 < sam_moore> You can improve it (if you get time) by having 2 images instead of one, with a symbolic link to swap between them
+16:38 < sam_moore> I'll bring the raspberry pi with the webcam tomorrow and we'll put everything on it to show Adrian
+16:38 < jtanx> hehehe
+16:38 < jtanx> can you install ffserver on the raspi?
+16:39 < sam_moore> Probably
+16:40 < jtanx> actually
+16:41 < jtanx> does our code run on the raspi?
+16:50 < sam_moore> Yes, at the moment
+16:54 < Callum> how are we integrating my code into it?
+17:01 < sam_moore> Keep it as a seperate process for now
+17:01 < Callum> alright
+17:01 < sam_moore> I'll modify the "run.sh" script to start both of them
+17:01 < sam_moore> Sigh javascript
+17:01 < sam_moore> So useful and yet so horrible
+17:02 < sam_moore> Still, I think if we can get our heads around it it is actually a nice way to do this
+17:09 < jtanx> the camera thing or the api or both?
+17:24 < sam_moore> The API
+17:24 < Callum> ok so how do i link to the image? (
+17:24 < sam_moore> Just put a html file in the /server directory for now
+17:25 < sam_moore> With <img src="path_to_image"> in the body somewhere
+17:29 < Callum> where are we going to put the images?
+17:31 < sam_moore> /server/images (?)
+17:31 < sam_moore> Wherever it seems logical I guess
+17:33 < sam_moore> If either of you are available earlier on Monday, I'm free for pretty much the whole day
+17:33 < sam_moore> Do you want to meet earlier and actually do coding as a group?
+17:37 < sam_moore> Dammit why does javascript remove the [] brackets when printing string representations of arrays
+17:37 < sam_moore> How are you supposed to tell what dimensions the array has...
+17:37 < jtanx> if you want sample code of how I printed the array of sensor values
+17:37 < jtanx> see the unit tests
+17:37 < sam_moore> Ok, thanks
+17:37 < jtanx> for (var i = 0; i < data.data.length; i++) {
+17:37 < jtanx> result += data.data[i][0] + ":" + data.data[i][1] + ", ";
+17:37 < jtanx> }
+17:56 < Callum> ok well iv done trhat, i think. you should probably check it to make sure its right
+17:58 < Callum> sent pull request. and i'v got food so brb
+17:58 < sam_moore> Ok, thanks
+17:59 < sam_moore> jtanx: You're right, altering variables on a successful ajax call is a pain in the ass
+17:59 < jtanx> hehe
+17:59 < sam_moore> ... You can modify html attributes really easily though
+17:59 < jtanx> true
+17:59 < jtanx> that's what I was thinking
+17:59 < sam_moore> Must resist urge to store data in a comment
+17:59 < jtanx> have a hidden input field?
+18:01 < jtanx> I must say that the firebug debugger and inbuilt web console were both quite useful
+18:02 < sam_moore> Yes, I've got firebug running
+18:04 < jtanx> I was looking at flask and it was ridiculously easy to set up a similar API in python
+18:05 < sam_moore> Do you want to change to python then?
+18:06 < sam_moore> Don't we still have to do the javascript though?
+18:07 < sam_moore> The API we have at the moment isn't that terrible
+18:07 < jtanx> nah
+18:07 < jtanx> it's probably best to stick with what we have
+18:07 < jtanx> the javascript stuff would remain the same yeah
+18:09 < sam_moore> Ok
+18:26 < sam_moore> Right... you can update global variables on a successful AJAX request
+18:27 < sam_moore> If you put "var" in front of the variable in the global scope then the AJAX callback will just make a new local variable and modify that -_-
+18:27 < sam_moore> But if you Don't put the "var" there, it will work
+18:40 < jtanx> lol
+18:41 < jtanx> but using global variables in javascript can get.... messy
+18:41 < sam_moore> Mmm
+18:42 < sam_moore> But doing pretty much *anything* in javascript is messy
+18:42 < jtanx> yeah
+18:42 < jtanx> true that
+18:43 < sam_moore> I wonder...
+18:43 < sam_moore> Should we just have one html page for each sensor/actuator
+18:43 < sam_moore> And then the user can open multiple tabs?
+18:45 < sam_moore> That's probably not very nice though
+18:46 < sam_moore> I think we should return data about multiple sensors at a time
+18:51 < jtanx> you'd probably want it all on one page
+18:51 < sam_moore> Yeah
+18:51 < jtanx> how many sensors are we talking about again
+18:51 < sam_moore> 6 or 7 I think, + a camera
+18:51 < jtanx> oh yeah
+18:51 < sam_moore> Oh well, we can redesign it later
+18:51 < jtanx> I guess we can design for max 7
+18:52 < sam_moore> But it might be a good idea to query multiple sensors in one ajax request
+18:53 < jtanx> yep
+18:53 < jtanx> supply more than one id in a go?
+18:53 < jtanx> could have an array (max size 7) that holds all the sensors you want to get data for
+18:53 < jtanx> i guess
+18:55 < sam_moore> It's probably more flexible to just add a "getall" key to the sensor module
+18:57 < jtanx> oh yeah
+18:57 < jtanx> I'm free until 12 tomorrow
+18:57 < jtanx> do you want to work together before that?
+18:58 < sam_moore> Sure
+18:59 < sam_moore> Try G19 again, but if that doesn't work we can go to the physics lab, or the computer science labs
+19:01 < jtanx> yeah ok
+19:02 < jtanx> what time do you want to start?
+19:04 < sam_moore> I'll probably get in around 9 or 10, depending on how much sleep I get
+19:04 < sam_moore> Let's say 10:00
+19:05 < sam_moore> Got to go, I'll be back later
+19:05 < jtanx> ok
+21:35 < sam_moore> I'm just going to use the same Sensor stuff for digital sensors
+21:36 < sam_moore> Adding a second type of sensor seems needlessly complicated
+21:36 < sam_moore> 1 = on and 0 = off
+21:37 < sam_moore> Probably do the same for actuators (just have some sanity checks on the values you can set, both at the client and the server)
+21:38 < jtanx> usually I'd just say 0 is off and not 0 is on
+21:38 < sam_moore> Haha, fair enough
+21:39 < jtanx> I kinda hate over-checking stuff :P
+21:39 < sam_moore> The actual GetData function has to return something reasonably sane though
+21:39 < sam_moore> It's easy to just make it only return 0 or 1
+21:39 < jtanx> oh I was more talking about setting the value of the actuator
+21:39 < sam_moore> Right
+21:40 < sam_moore> We should probably check for 0 or 1 anyway
+21:40 < sam_moore> In case the user does something dumb
+21:40 < jtanx> well
+21:40 < sam_moore> Like think they are setting an analog sensor and put in like "200"
+21:40 < jtanx> it should be the js code that's setting it
+21:41 < jtanx> so if you write the code properly it shoul be ok
+21:41 < sam_moore> "should be OK"...
+21:41 < jtanx> you shouldn't access the api directly
+21:41 < sam_moore> Alright, we'll see, but it's like, 1/2 a line of code to check :P
+21:41 < sam_moore> Redundancy and all that
+21:41 < jtanx> but even if they entered 200
+21:41 < jtanx> well so what
+21:41 < sam_moore> Yeah, but people *can* access the API directly
+21:41 < jtanx> it'd just represet 1
+21:42 < jtanx> represent
+21:42 < jtanx> *
+21:42 < sam_moore> How does the server know the difference between someone typing the URL and an AJAX request to the URL?
+21:42 < jtanx> yeah
+21:42 < sam_moore> Someone could go view source, "How can I break this... ah, what happens if I pass stupid values directly to the API"
+21:42 < jtanx> well if you define that 0 is off and not zero is on
+21:43 < jtanx> then it meets specs :P
+21:43 < sam_moore> Ok, I suppose it doesn't really matter
+21:44 < sam_moore> I respectfully disagree with the idea of having too many checks :P
+21:44 < sam_moore> Unless we went "while (true) DoCheck();" or something like that
+21:44 < sam_moore> That would be dumb
+21:44 < jtanx> hahaha
+21:45 < jtanx> but sometimes it gets really messy to maintain when you have that many checks
+21:45 < jtanx> and then when you want to modify something it's a real pain
+21:45 < jtanx> and really easy to break
+21:45 < sam_moore> True, but a bounds check isn't that bad
+21:46 < jtanx> yrue
+21:46 < sam_moore> I mean, you have to convert the value that isn't zero to an "on" anyway, which requires a check
+21:46 < jtanx> not really
+21:46 < sam_moore> Depends on the actuator
+21:46 < jtanx> you check if !value
+21:47 < sam_moore> Alright
+21:58 < jtanx> do you think there should be a stop/start method?
+21:58 < jtanx> eg start the experiment
+21:58 < jtanx> stop the experiment
+22:28 < sam_moore> Yes, probably
+22:28 < sam_moore> The stuff I wrote for Thread Exit conditions may actually help there...
+22:29 < sam_moore> Remove the bit where the FCGI loop exits though
+22:29 < jtanx> yeah
