NOTE: code accompanying this text [here][11].

After [my initial flirting with some advanced python][2] for the backend at Lone Rooftop, in the end we decided to go all-in on the nodejs trail. There are a number of reasons for this.

1. Even though it's quite doable to keep two languages in one's head, python for server-side, and javascript client-side, I do still notice that I mix them up (answer quickly: how to add an element to a python list? And how to a javascript array?). And wouldn't it be better to only have to keep one in one's head (and use the saved brain-space to keep more of the application in there)?
2. Like any developer I spened a lot of time setting up my editor (in my case vim) in just the way I like it. It's probably better to only have to do this once, for one language, then having to do this twice. And personally I don't believe in editors that come fully set-up.... In the end there is always some small thing that I'd like to change.
3. Even though the two points above are minor nuisanc

OK, so I am new to IPhone development, but I guess this is an error I won't be making any more!

In iOS 5.1, this code should have printed a lot of "Yeah, we've got something"'s... But in stead, all I got was Mar 15 00:54:47 unknown mediaserverd[43] <Error>: 00:54:47.702 <0x2745000> AURemoteIO::ChangeHardwareFormats: error -10875

NOTE: colons in file names are directory separators (which are not allowed in gist...)
NOTE2: Actually it doesn't like colons either, so all files are here twice now and I can't remove them.... Have fun with them :)
NOTE3: Very likely the appengine dependency is not even needed. Doesn't hurt though and is most likely useful later....


These 4 files will make a project that runs on appengine.

To run:
lein dep
lein compile

I was looking for a CSS-only solution to fade a page overlay in and out. Obviously this should do the trick:

#loadingIndicator {position: absolute, z-index: 1;  opacity: 0; -webkit-transition: opacity 2s; }
body.loading #appLoadingIndicator { opacity: 0.8; }

However, this leaves an invisible layer on top of everything, which catches all clicks or other mouse events. This problem seems to have come up more often (http://stackoverflow.com/questions/4178567/webkit-transition-with-display). The solution is to use a transition on 2 properties, and move the layer out of the way after it has faded out:

#loadingIndicator {position: absolute, z-index: 1;  top: -1000px; opacity: 0.2; -webkit-transition-property: opacity, top; -webkit-transition-duration: 2s,0; -webkit-transition-delay: 0, 2s; }
body.loading #appLoadingIndicator { opacity: 0.8; top: 0; -webkit-transition-delay: 0,0;}
