Do any open source libraries exist for programatically selecting and rating the compatibility of sets of colors using color theory?
It would be very useful to be able to select color palettes based on simple color harmony rules like complimentary, analogous, triadic, and tetradic colors.
I just found this: Harmonies theory and math.
Also of interest is the rest of the EasyRGB site, which will explain how to do RGB to HSV, etc.
While it's not source code, it's the formulas for calculating the values.
Also interesting: "Color Jack"
This isn't a direct answer and it's not open source, but you might take a look at what they are doing at Adobe's Kuler web site. They have API Documentation that might be worth a read.

I want to learn to make beautiful Android apps.
The things I want to know more about are:
- how to create drawables (with / without states)
- apply borders, change backgrounds
- styling / customising action bar
The resources on developer.android are sparse, I need something in-depth.
Thanks.
First of all developer.android is enough for UI styling if you have gone through all the tutorials thoroughly, however you can have a look at the following links, very informative for UI styling :
Link 1
Link 2

I am looking for a complete set of icons representing the keys on the keyboard. Preferably licensed so I can use them.
It would be awesome if each key had a corresponding 'pressed' icon.
Does anyone know where I might find one?
I guess this is what you are searching for: Free Keyboard Graphics and Key Icons - speedflips. Keyboard key icons as SVG and PNG graphics.
License: Public Domain - Free for commercial and private use

Hope that helps :)
This is what I found:

You can't use them for commercial use, have to post an attribution, and there is no 'pressed' version of each key.

I have a hugh graph structure like wikipedia. I have the adjacency list for the graph as it is very sparse. Is there a open source software to visualize the graph and zoom in and out.
Gephi would be a good solution. It offers many display styles and layouts as well as using OpenGL to render the graph which makes it fast. It can also read a variety of formats and is extensible.
GraphViz is a very well known OSS graphing tool. If you can print your graph in one of its supported formats you should be ready to go.

I need a Diagram Tool with ability to extend set of diagram types and diagram primitives and save them as templates for future use. User-scripted exports or export formats for my diagrams would be nice, too.
For example, I want to make something like this in my game programming:
http://www.bigbluecup.com/yabb/index.php?topic=38322.0
Now I use great UML-only RationalRose-like editor StarUML. It is very comfortable, stable and I like it very much.
I can think of some options:
Ditaa
PGF/TikZ (uses LaTeX)
Graphviz
Dia
Would any of those help you out? TikZ has been my choice for diagrams since I found it. I don't know if there's anything you can't do. Check out the TikZ examples page. Sorry if I totally missed what you're looking for and provided silly suggestions!

Is there a place where I can find all the keycodes for keys on a keyboard? (For example, the key up may be #114)
I can't seem to find one no matter what I search :(
Thanks!
Here's a list of keycodes that includes a way to look them up interactively.
I know this was asked awhile back, but I found a comprehensive list of the virtual keyboard key codes right in MSDN, for use in C/C++. This also includes the mouse events. Note it is different than the javascript key codes (I noticed it around the VK_OEM section).
Here's the link:

You don't mention what language you want to track these in, but I found two for javascript:
