Can anybody give me some examples and brief explanation of parallel computing in image processing (that could make use of CUDA kernels on an Nvdia GPU) ? For example with regards to pixels my perception so far is that the image could be split into smaller sections and same process applied to those sections to build the overall objective, but is there more to it than that? Also how would that be achieved in terms of programming?

I am working on finding the similarity/differences in the source code of different java programs.
I've used an implementation of the Levenshtein algorithm to find how similar two programs are.
I want to know if there is any algorithm that can help in finding the exact positions where two strings differ.
You will find more than you ever wanted to know by looking at the inner workings of diff - see for example this link or simply the wiki article

I am having some troubles in implementing Force Directed Layout in Haskell. The algorithm is based on considering the entire graph as a physical system, the force are applied to the nodes , pulling them closer or pushing them further apart. Quite new to Haskell, so can you tell me which module to draw graph, objects, to visual things in Haskell. Or some idea to start with this algorithm?
which module to draw graph
Perhaps graphviz, or for a more complete solution, you might try force-layout, the first hit on Google for "force layout haskell".

On Shai's blog entry about Searchable list, I noticed that he commented that since he optimized LWUIT some things are broken.
I want to implement search on my list in LWUIT, please how do I implement? Some basic examples would also be very helpful, thank you.
The only thing you need to do is explicitly invoke form.registerAnimated() which was missing in my original demo code.

How are treated constants in various languages/compilers? They take up space in RAM in runtime or are replaced with their values at compile time?
A compiler is free to go either way. The typical way to handle this is to use scalars directly while keeping larger objects like arrays in memory.
In addition, if you build an embedded system, they typically go into read-only memory like flash rather than RAM.

How many background workers can I use? Threads? etc.
Tha maximum number of threads you can create is only bounded by the resources that you have.
This could be the question asked in:
Maximum number of threads per
process in Linux?
What's the maximum number of threads
in Windows Server 2003?
Depends on your hardware/software configuration and your use cases.
