+15:10 < jtanx> urgh
+15:10 < jtanx> burning the midnight oil trying to get my cits2232 project done
+15:10 < jtanx> but
+15:10 < jtanx> it has taught me a lot about django
+15:10 < jtanx> which may be of use, especially for the whole admin stuff
+15:11 < jtanx> one possibility is that we have two separate 'logins'
+15:11 < jtanx> one gains you access to the site
+15:11 < jtanx> one gains control over the bbb (eg the server api)
+15:12 < jtanx> what you could do is keep the 'bind' functionality for the api, but make it check against the django user database for credentials
+15:12 < jtanx> I'll look into it, if not today then probably tomorrow
+19:39 < sam_moore> That sounds good
+19:48 < sam_moore> Should we do something like this: http://stackoverflow.com/questions/8988855/include-another-html-file-in-a-html-file (The accepted answer) to do with our sidebar/menu stuff
+19:48 < sam_moore> Although...
+19:48 < jtanx> well
+19:48 < jtanx> if we use django it has really cool templating stuff
+19:48 < sam_moore> That solution is actually about as much as just copy/pasting the sidebar at the moment
+19:48 < jtanx> yeah
+19:49 < sam_moore> So Django does parts of our GUI as well as the user management system?
+19:49 < jtanx> Well yeah
+19:49 < jtanx> so django would be ui mostly
+19:49 < jtanx> then tack on to that our api
+19:49 < jtanx> which remains exactly the same
+19:49 < jtanx> except that it uses the django database for checking authorizaiton
+19:50 < jtanx> so right before you commence an experiment, you try to 'gain control' of the bbb, you resupply your login creds
+19:50 < sam_moore> Sure, that's a good solution, I thought django would just do user management though (rather than replace the JavaScript GUI)
+19:50 < jtanx> well if you do use django
+19:50 < jtanx> it's a good idea to change some of it, because of the templating system
+19:51 < jtanx> and that it can conditionally show content
+19:51 < sam_moore> Ok
+19:51 < jtanx> some of the javascript stuff will stay though, definitely
+19:51 < jtanx> especially all the live update stuff
+19:51 < jtanx> but this is getting ahead of myself, because i'm not even sure if this will work
+19:51 < sam_moore> Hahaha
+19:52 < sam_moore> You're entering a territory where I can't help much
+19:52 < jtanx> yeah, well all of this 'web development' is new area for me too :P
+19:52 < jtanx> I'm supposed to be majoring in computation, not web tech...
+19:52 < sam_moore> You know more/better jQuery than me
+19:52 < jtanx> jquery is pretty easy to learn though
+19:53 < jtanx> i picked it up completely from this project
+19:53 < sam_moore> Well, that's one reason why we went with it, since I used it briefly for something and it wasn't too hard, and James said he'd used it before too
+19:54 < jtanx> Yeah
+19:54 < sam_moore> If you want to replace stuff with django, I'm ok with that, if it's simpler
+19:55 < jtanx> I'll see how it goes, hopefully it shouldn't be too hard to setup
+19:55 < sam_moore> It just seems silly to copy/paste this Navigation Menu into every file
+19:55 < jtanx> yep
+19:55 < sam_moore> But copy/pasting the code (stack overflow) to automatically make it is also annoying
+19:55 < jtanx> We can roll with the jquery soln if I don't get this working
+19:56 < sam_moore> Unless you could include that in the "runBeforeLoad()" ?
+19:56 < jtanx> can't you just have a placeholder
+19:56 < jtanx> and on document load, you load it?
+19:56 < sam_moore> Yeah
+19:56 < jtanx> It'll look a bit crap because you'll see it before the sidebar loads
+19:56 < sam_moore> Actually that's how you're doing other things
+19:56 < jtanx> yeah
+19:56 < sam_moore> But the navigation menu is hard coded html
+19:56 < sam_moore> I'm just reading the existing code :P
+19:56 < jtanx> haha
+19:57 < jtanx> yeah it's hardcoded - it's the easiest solution
+19:57 < jtanx> I've got my case study for 2402 this/next week too
+19:57 < sam_moore> Um... I think it's fairly easy to call load from a file
+19:57 < sam_moore> I'll look into that
+19:57 < jtanx> ok
+19:58 < sam_moore> The case study was reasonable, although he wanted a lot more detail from us
+19:58 < jtanx> what did you do?
+19:58 < sam_moore> Despite struggling to cram it into 4 pages
+19:58 < sam_moore> The pencil
+19:58 < sam_moore> That's a good one
+19:58 < jtanx> ah
+19:58 < sam_moore> Lots of youtube videos
+19:58 < jtanx> we're doing pet bottles
+19:58 < jtanx> there's this megafactories one on the coke plant which was prettyc ool
+19:58 < jtanx> but yeah the pencil one also has a lot
+19:58 < jtanx> i think i saw the how its made one
+19:59 < jtanx> Ha
+19:59 < jtanx> http://wiki.nginx.org/HttpSsiModule
+19:59 < jtanx> if you want to get server specific
+19:59 < jtanx> you can do ssi
+19:59 < jtanx> let's not do that if possible :P
+20:00 < sam_moore> Wait...
+20:00 < sam_moore> It looks like you put html comments and they get sent to the server?
+20:00 < sam_moore> How is that a thing?
+20:00 < jtanx> <!--# include file="footer.html" -->
+20:00 < jtanx> nah what happens
+20:00 < jtanx> is the server reads the html file
+20:00 < jtanx> and where there's special placeholders
+20:00 < jtanx> it does stuff
+20:00 < sam_moore> Ah
+20:01 < sam_moore> No, do it client side
+20:01 < jtanx> yeah
+20:01 < sam_moore> There's like jQuery.load
+20:01 < sam_moore> I'd probably keep django for user auth to start with
+20:01 < sam_moore> But I think jQuery should be sufficient for the GUI
+20:02 < jtanx> I think if you roll with django
+20:02 < jtanx> you should use jQuery for all the interactive stuff
+20:02 < jtanx> (which you'd have to anyway)
+20:02 < jtanx> but you should use the templating system that django's got
+20:03 < sam_moore> Ok, what does django give you exactly then, I'm not quite sure what the "template" stuff is, I assume it's nothing like a C++ template
+20:03 < jtanx> OK
+20:03 < jtanx> hmm
+20:03 < jtanx> I'll give you access to my cits2232 repo temporarily
+20:03 < jtanx> so you can see
+20:03 < sam_moore> If it lets you easily include bits of html that's cool, but jQuery looks to be able to do that easily as well
+20:03 < sam_moore> Alright
+20:04 < jtanx> actually you know what
+20:04 < jtanx> i'll just post it on pastebin or something
+20:05 < jtanx> http://privatepaste.com/ec22ba7238
+20:05 < jtanx> That's the base template
+20:05 < jtanx> http://privatepaste.com/07499e4a19
+20:05 < jtanx> That's the index
+20:05 < jtanx> {{variable_name}} will display a variable name
+20:05 < jtanx> sorry, the contents of that variable
+20:06 < jtanx> {% %} blocks are for control
+20:06 < sam_moore> Hmm
+20:07 < jtanx> the base template got a bit out of hand for that project
+20:07 < sam_moore> Well, if you want to use something like that I'm ok with it
+20:07 < sam_moore> Although I think the thing that I was originally complaining about can be solved in jQuery :P
+20:08 < jtanx> yeah
+20:08 < sam_moore> But you should probably ask everyone else involved with the GUI for input too
+20:08 < jtanx> Yeah, good point
+20:09 < sam_moore> ... Really I didn't want to be involved with the GUI, but I kind of need to mess around with at least some basic graph stuff to work out if I need to change the server sensors/actuators api
+20:09 < jtanx> well let's just say that i did not envision doing the gui either
+20:09 < sam_moore> I'll try and keep what I do consistent with the overall style though
+20:09 < sam_moore> Which is how I got sidetracked complaining about copy/pasting things :P
+20:10 < sam_moore> I think the GUI we have so far is pretty good
+20:10 < jtanx> hehehe
+20:10 < jtanx> yeah it's not too bad
+20:11 < jtanx> the only thing that I wouldn't know how to do is that admin stuff
+20:11 < sam_moore> user admin or experiment admin?
+20:11 < jtanx> um
+20:11 < jtanx> I dunno, whatever that 'admin' functionality needs to be
+20:11 < jtanx> like 'access the full logs'
+20:11 < sam_moore> Oh, right
+20:12 < jtanx> unless you start implementing permissions in the api
+20:12 < sam_moore> Hmm, we might have to
+20:13 < sam_moore> It should just be an enum for the user type that gets returned/set by the authentication handler and checked for certain operations
+20:13 < sam_moore> But as you mentioned the other day, you don't want someone to be able to login after someone else has started an experiment and cancel it
+20:13 < sam_moore> Actually
+20:13 < sam_moore> Do you?
+20:13 < jtanx> admin only?
+20:13 < sam_moore> Exactly
+20:14 < jtanx> how difficult is that to do though
+20:14 < sam_moore> Store the username of who owns the current experiment
+20:14 < sam_moore> Store an enum of the user type of whoever is currently logged in
+20:14 < sam_moore> If someone tries to stop the experiment, unless their username matches, or they are an admin, refuse
+20:14 < sam_moore> There could be a safety issue there?
+20:15 < jtanx> the only thing is
+20:15 < sam_moore> If someone needs to stop the experiment but isn't an admin?
+20:15 < jtanx> everything's based off the control key
+20:15 < sam_moore> Meh... add another cookie
+20:15 < sam_moore> ... That escalated quickly
+20:15 < jtanx> you've already used the nameless cookie
+20:15 < jtanx> if you add another cookie
+20:15 < jtanx> you have to do string parsing
+20:15 < jtanx> and have named cookies
+20:16 < sam_moore> Hmmm
+20:16 < sam_moore> "Beyond the scope of the project" ?
+20:16 < jtanx> i think the format was
+20:16 < jtanx> key=value; key=value2
+20:16 < jtanx> yeah, beyond the scope :P
+20:16 < sam_moore> Yeah, that is ever so annoying
+20:16 < jtanx> let's leave it for now
+20:16 < jtanx> come back to it
+20:16 < sam_moore> Because if it were something like "key=value&key=value2" you could potentially reuse the FCGI parser
+20:17 < jtanx> yeah
+20:17 < jtanx> you could modify it
+20:17 < sam_moore> That would be the way to go
+20:17 < jtanx> generalise it
+20:17 < sam_moore> But it's low priority now
+20:17 < jtanx> yep
+20:17 < jtanx> wow i'm getting seriously sidetracked
+20:18 < jtanx> this mechatronics project is more interesting than any of my other projects though
+20:18 < sam_moore> Haha
+20:19 < sam_moore> I know what you mean
+20:19 < sam_moore> I want to compile a RT linux kernel on my laptop (since they have x86 versions)
+20:19 < sam_moore> So that I can look at how much the consistency in sample rate could theoretically improve...
+20:20 < sam_moore> If someone managed to port the RT linux kernel to the BeagleBone
+20:20 < jtanx> RT linux on your computer
+20:20 < jtanx> isn't that generally bad
+20:20 < jtanx> because RT screws up other stuff
+20:21 < sam_moore> Like what?
+20:21 < jtanx> decreased performance to meet the deadlines
+20:21 < sam_moore> Also, I don't have to permanently replace my existing kernel, just add another bootloader entry
+20:22 < sam_moore> If it screws up nginx that would be annoying though
+20:23 < jtanx> while you're at it, try running the bfs scheduler instead of the cfs scheduler :P
+20:23 < sam_moore> Maybe
+20:42 < sam_moore> Ok, the solution to the copy/paste is just something like $("#sidebar").load("static/sidebar.html")
+20:42 < sam_moore> However, whilst running this in the document.ready function on a test page works, running it in index.html appears to have no effect
+20:43 < sam_moore> Oh
+20:43 < sam_moore> I know why
+20:43 < sam_moore> Because runBeforeLoad is failing
+20:43 < sam_moore> Presumably you still want to load content like the navigation bar even if the server isn't running
+20:44 < sam_moore> So... there is ".done()" and ".fail()" ... is there ".either()"?
+20:46 < sam_moore> Ahahaha
+20:47 < sam_moore> Of course, there is ".always()"
+20:49 < sam_moore> Hmm, I wouldn't want to design any sort of large system with a language like this, but it is an interesting style
+20:51 < jtanx> haha
+20:52 < sam_moore> So, a lot of the header stuff can be moved into .html files and just jQuery.loaded, which should make things cleaner
+20:52 < sam_moore> I will refrain from doing that now though
+20:53 < jtanx> don't be too tempted to do a lot of templating with javascript
+20:53 < jtanx> because it will load asynchronously, stuff will look weird
+20:53 < jtanx> and if the js breaks
+20:53 < jtanx> well, your page is more screwed than before
+20:54 < sam_moore> Ok... but you could still potentially have at least one html file in the static directory
+20:54 < sam_moore> With all the header and navigation stuff
+20:55 < sam_moore> Just have a .fail() function!
+20:55 < sam_moore> That's what it's for, right :P
+20:56 < sam_moore> $("#thing").load("static/thing.html").fail($("#thing").html("<p> Something fucked up </p>")
+20:56 < sam_moore> Oh dear
+20:58 < jtanx> ~.~
+20:58 < jtanx> django here: https://mctx.us.to:8043/databases
+20:58 < jtanx> login with testuser:testuser
+20:58 < jtanx> ignore that it looks a lot like our gui
+20:58 < jtanx> except it doesnt work anymore
+21:00 < sam_moore> Well, django's used for UCC for member administration
+21:01 < sam_moore> Except it's entirely seperate from LDAP which we use for authentication
+21:01 < sam_moore> Except it's not really because it binds to LDAP for authentication :S
+21:01 < sam_moore> Wheels within wheels...
+21:02 < jtanx> ookay
+21:04 < sam_moore> You need LDAP for shell access
+21:04 < sam_moore> In fact...
+21:04 < sam_moore> We could potentially give pheme users shell access to the BeagleBone
+21:04 < sam_moore> But there's not really any point
+21:04 < jtanx> is that a good idea
+21:05 < sam_moore> No
+21:05 < sam_moore> It's an awful idea
+21:05 < sam_moore> Just saying it's possible :P
+21:06 < sam_moore> Someone could do this: :(){ :|:& };:
+21:06 < sam_moore> And break the entire thing
+21:08 < jtanx> is that the fork bomb
+21:09 < jtanx> ok the site works now
+21:09 < jtanx> sort of
+21:10 < sam_moore> 400 Bad Request
+21:10 < jtanx> hurr
+21:10 < sam_moore> I think iceweasel is being dumb and ignoring https:// ?
+21:10 < sam_moore> Although it was fine before
+21:11 < jtanx> nah probably screwed up the nginx config
+21:11 < sam_moore> No, it works, I just had to type the https:// instead of copy paste
+21:11 < sam_moore> Wierd
+21:11 < sam_moore> The test login doesn't work though
+21:11 < jtanx> testuser doesn't work for some reason
+21:11 < jtanx> yeah just register
+21:12 < sam_moore> Will it actually send an email?
+21:12 < jtanx> urgh
+21:12 < jtanx> no
+21:12 < sam_moore> haha
+21:12 < jtanx> okay no the config is still broken
+21:16 < sam_moore> I'll have to come back to this tomorrow
+21:16 < sam_moore> Bye
+21:17 < jtanx> ok bye
