I want to understand how exactly the OMG Data distribution service works and how it can be used for real time inter process communication with better performance.Please suggest me the best resources/books? i tried with Google and YouTube but could not able to get the exact DDS functionality related information and DDS implementation in real time.
The Data Distribution Service Portal at the OMG contains several tutorials contributed by the different vendors. See http://portals.omg.org/dds/tutorials these can be good references as they tend to focus on the standard features and less on vendor-specific details.
That said several of the vendors have created excellent tutorials. In addition to the one mentioned in the previous post I like the one by Twin Oaks Computing. The whole tutorial fits in one (long) HTML page with nice concept and figures: http://www.twinoakscomputing.com/coredx/dds_tour
For more in depth coverage I like the eLearning program from RTI (the company where I work) http://www.rti.com/elearning/index.html
Two of the modules that are available for free provide very good intro material on concepts and design patterns:
Introduction -- http://vimeo.com/user14186439/review/57448029/6138f1e5c1
Instances Samples and Data-Types -- http://vimeo.com/user14186439/review/61771143/d59ca69515
Also I would recommend the Case+Code (use-case) examples in the RTI Community Portal. They provide complete code examples illustrating how the different DDS APIs and QoS can be use to meet realistic use-cases. See http://community.rti.com/case-and-code

No books that I know of, but I like this paper...
http://www.slideshare.net/Angelo.Corsaro/the-data-distribution-service-tutorial
It guides you through some of the features of DDS and how you could utilize them by referring to a temperature sensor example.
If you want something more hands-on, there is an Open Source implementation of DDS at
http://www.prismtech.com/opensplice/opensplice-dds-community
which contains a set of examples and a lot of other documentation about the features and API.
Thanks

I want to develop some HAL (Hardware Abstraction Layers) to use in PIC32 and some ARM.
Basically I want to make some code that's usually available on a OS, like generic pin access, communication libraries, device I/O, etc.
Could you advise me with good books/websites?
I'll start with one that I've found a few weeks ago: http://www.kalinskyassociates.com/OnLineLearning.html
Thanks
Have you tried looking at some implementations?
eCos has a HAL, which has some documentation to go along with it.
eLua also has a HAL that has grown around it to support the platforms it runs on (ARM, AVR32, etc..), check the architecture information and the "Platform Interface" and "Generic Modules" menus. If you strip out the Lua, eLua is essentially a HAL.
There are likely other examples as well, but I'd recommend looking at living examples of cross-platform and non-cross-platform hardware APIs. Also, if/when you go and start putting together interfaces, make sure to examine individual platform peripheral implementations before nailing down the API. You will find that certain interaction models are commonly supported across many platforms, and others are very platform specific. If your API assumes functionality will always be available, it will be difficult to port to platforms that either have lacking or non-existent support for the functionality you want. Sometimes you may be able to work around this in software with simple solutions, other times you may find it is either impossible or horribly complicated to make behavior consistent across platforms.
You can try also looking at the OSEK interface documents. The standard does a good job of abstracting accesses to most commonly used peripherals. However, bear in mind that this is only a spec and you'd have to work out all implementation details.

What tools exist for developing platform indepedent API Documentation?
I'm in the process of designing a proposed API, and want to write documentation in a structured and easily editable way. A lot of the answers I've seen have basically been "Use built in language specific documentation tools", but since I'm designing the API from a 'top-level', rather than implementing it, this isn't so useful. I'm looking for a CMS for API Documentation
I've seen a few suggestions to use PBWiki or Confluence, but I'm not convinced that a plain wiki is the best option, though the version control aspects are nice.
In theory, a Drupal build with CCK for API calls and Views for reading the API, but that's a bit of heavy lifting for what I'm looking for.
Is there a API Documentation Management System out there? What are the best options for writing and managing platform-independent documentation for APIs?
I've seen the related questions for this, but there has yet to be a satisfactory answer.
Any structured text language will do. I'd use latex, and troff is old school.
But you may have missed the point of the suggestion to use doxygen or whatever. If you do that, then writing the documentation is also laying down the scaffold for the eventual implementation. Better still, the example documentation will be in the same format as the eventual real documentation and, you will--of course---use source control on it, won't you? So you'll have a potted history of changes to the spec.

What websites (not books) document designs (UML or otherwise) for software applications?
Building architects have many resources available for inspiration and construction. I do not seek resources on constructing software (such as Meyer's Object-Oriented Software Construction), but rather examples of designs for software components or class diagrams that can be used as a starting point for developing an applcation.
Example applications might include:
Game System
Word Processor
User Interface
Telephony Call Control
Clinic Scheduling
Notification System
Incident Management
Network Monitoring
Restaurant Catering
Dispatching (Taxi, Police)
Selling Vacation Packages
The Design Patterns book is a good start, but a bit too low level.
Grady Booch has a great site for just this thing at
http://www.handbookofsoftwarearchitecture.com/index.jsp?page=Main
But you do have to register to look at the diagrams.
Do you mean things like Microsoft's Patterns and Practices?
For simple explanations, sample codes and use cases of common software design patterns, you can check out http://sourcemaking.com/design_patterns. They are generally aimed at solving common problems and can, in fact, be considered as re-usable architectures in software development.
For information related to domain-specific systems, such as games, there can be other domain-specific problems that have been addressed in different architectures, such as some of the links you have provided. Finding a single source which can list all this information in a unified architecture may not be possible, at best. Generic design patterns, such as those from the Gang of Four, is a better start for this reason, I believe.

A lot of you have starting to write programs since college or even earlier.
When you were on university the level of professionalism increased.
If you have to write an article about your software application how do you do it? I'm not talking about a documentation or help manual. I'm talking about an article/paper for academia world. Do you have any idea where can I find those type of articles for free?
This is also a programmer job, even we like to do it or not.
Here's one I made (much) earlier.
Abstract:
This paper presents details of the
Safety Argument Manager (SAM) a PC
based tool to support safety case
construction. SAM is novel in that it
stresses total system safety and is
designed to support an integrated
process for design and assessment. SAM
provides facilities for the
construction of high level safety
arguments and for building up complete
and consistent supporting evidence. In
this paper we focus on the achievement
of high quality supporting evidence,
by describing SAM's facilities for
integrated modeling and safety
assessment. We also illustrate the use
of SAM with a car braking system
example.
What it does, why it's novel, how it does it at a high level, small concrete example shown end-to-end.
Usually papers are rarely about software itself but rather about concepts, ideas and algorithms. Those are explored through software and the authors may give specific examples how they implemented those in their software but most papers are not specifically about a software application itself as those usually have very little valuable content.
There are only few of such papers I've come across so far:
SPRNG: a scalable library for pseudorandom number generation.
Presto: An Experimental Architecture for Fluid Interactive Document Spaces.
Other papers may follow which then concentrate on how specific optimizations or changes were implemented and also new ideas. But I think in those areas real innovation is rare and there is much more text than actual content.
Google Scholar is exceptionally useful for finding freely available academic publications, particularly in the CS/software world.
While many peer-reviewed journals hide things behind paywalls, academics have a tendency to publish working versions or drafts on their personal websites and such. You can find these using Google Scholar (by clicking the "See all X versions" link).

I'm working on an app to provide an easy way for people to track the status of a bill [and various other political information]. I love the idea of OpenCongress, for instance, which surfaces summary information on legislation as it navigates the political process, but I'd like it if it had a tag-based search system and some other rich search options, as well as more conveniently accessible voting history and term information. And while they now have JavaScript widgets which show the current status of bills you select, I think more could be done in this regard.
I don't know where they get their data, though, and while they have an API of their own, I don't know whether sticking a wart onto it is the best way of implementing what I envision. For all its touting of transparency, it's not at all obvious to me what data the government makes available, or even how to find that out!
So, does anyone know any good APIs for obtaining information on the status of American legislation, legislators (such as voting histories), agencies and/or upcoming elections? (Or, if you think it's really interesting, feel free to post any other APIs that are relevant to U.S. politics.)
Although they aren't APIs, www.data.gov provides official data sets, which can be mined. For now, I think this is the closest you're going to get to an official, centralized source of data.
Check out ProgrammableWeb's list of government-related APIs. Not all of them are the US federal government, so you might need to sift through it a bit. Also, they're not all provided directly by the government.
There's also an open source project that provides an API for thomas.loc.gov.
We publish feeds of all legislative information for the New York State Senate, with an API, at: http://open.nysenate.gov/legislation/developers
I'm not sure if it addresses exactly your concerns but the Watchdog site tries to do something like this. Their source is available online and they extract a lot of information from public records. A lot of the published stuff is in rather antiquated formats (huge zipped XML files) and so the whole process is not totally straightforward.
