I'm new to OpenCL in order to need help on choosing a language for writing a OpenCL program, There are many language(like c/c++ , python , java) available for that. I want to develop a application on distributed OpenCL using VirtualCL.

I will suggest you to use C++ for OpenCL program.
But literly speaking, the reason to use C++ rather than other languages is performance.
It is very fast at runtime than other languages.This allows writing very efficient code that still has high abstraction level.
The best way to phrase it is :
Less code, no run-time overhead, more safety.

I was told once there is a book that shows you how to make a database from scratch using sed, awk, and the Linux filesystem. I thought I had the name, but now I cannot find it. What is this book called?
Edit:
My understanding is this book was meant for learning how databases work, and how to build your own entirely from scratch using awk and the filesystem. From how it was explained, you could build your own version of /rdb, then when you finished you could just use /rdb itself, but now you'd know how it was made.
So, at the end of the book, you'd have almost completely remade /rdb yourself.
Is it "Unix Relational Database Management: Application Development in the Unix Environment (/RDB)" http://www.amazon.com/exec/obidos/ISBN=013938622X/cbbrownecompu-20/ ?

i'm trying to develop an 3D graphic application on my SAMA5D34-EK board(cortex A5 ARM without GPU), seems the openGL cannot be used.
Anyone can tell me some other alternative solution to do that?
You could try Mesa 3D's software renderer, it's essentially OpenGL implemented all in software.
Your CPU seems to have some graphics-acceleration built-in, so if you could use that perhaps you'd gain performance. Probably not though, all the linked-in document says is:
[The] peripheral set includes an LCD controller with overlays for hardware-accelerated image composition [...]
So that might be too narrowly focused to be useful in a general-purpose rendering solution. I didn't chase down any more detailed documentation, so it's hard to be sure.
Also, using such acceleration might mean writing your own low-level engine/renderer though, which would probably be a very large project.

I am wanting to find Motif widgets for Python3 similar to the popular Python module "PyQt4". I have not found a Motif-widgets module. Do any exist?
WxWidgets apparently has Motif bindings so, conceptually, you might be able to build the development version of WxPython, which supports Python 3, from source, with wxMotif.
However, even if it this will work, I suspect it won't be an easy process, and unless you have a really good reason for wanting to use Motif, using the Qt bindings (either PyQt or PySide) seems like a much more future proof option, better supported and with a lot more features.

Does anyone know of any software like Google Docs, or collabedit that allows you to edit realtime collaboratively and even compile a .cpp or other program over the web?
I haven't used this website, but seems like http://codebunk.com/ does the job.
It doesn't work for Java though.
I know of this website that will compile the code for you:
http://ideone.com/
Unfortunately, I cannot help in the real time editing front.
I wrote a little webapp that does exactly that, i.e. it lets you compile Google Docs documents: http://compiler.m01.eu
You can write C++ code into a Google Document (and do that collaboratively if you like), and then click on a bookmark (provided on the site) to compile your code, which will either start the download of your binary or show a compiler error message.

I'm curious if anyone is using any web app that is extremely simple (very few lines of code). Something that helps you with something practical in your daily life? I'm learning JavaScript and I would like to see examples so that I can build my own, but I want it to be useful so I feel motivated enough to build it.
The d3 page has some awesome examples of really neat yet simple applications: http://mbostock.github.com/d3/
