I have searched google and this site but was unable to find any tutorials on the Rdata format.
Can someone point me to one?
What I would like to know is basically how to use it and what its advantages/disadvantages are.
Can I store any type of data structure in Rdata? Can I save an Rdata file and update it with new entries? etc.
An Rdata file is a binary file, whereas csv files, for example, are text files. Advantages of Rdata format is that it is more compact, faster to read, and can store any type of R data structure. Furthermore, you can store several objects into one Rdata file.
On the other hand, it is a format which is incompatible with other statistical systems or software. So you won't be able to send data in this format to someone who is not using R. Furthermore, it may become incompatible from one R version to another (even if the compatibility is maintained since version 1.4).
You can find more informations in the ?save help page.

Is there a place where I can view the DOS nethack source code? Whenever I try to download the source code file it doesn't let me open the file. Is there a website/online pdf that has the code on it? Also if there are any tutorials on a beginning c++ roguelike could you tell me the link? Thank you.
You can download the source code here. But FYI no it doesn't come (displayed) on a website/online or in a pdf because that's not really a useful way to store or pass along source code. The useful way to store it is in the file types for the language the code is for.

For private usage I am looking for a simple document management system (NOT a Web CMS). The requirements are relatively simple :
Web based
Free, prefer open-source
Able to store electronic documents (Word, PDF, ...) and scanned paper documents (in PDF/jpeg/whatever image format)
OCR support
Along with some metadata : name of the doc, project/department to which it belongs, author, date, place, some identifiying code, a short description,...
Using different storage (NAS, Dropbox, WebDAV)
Optional but nice
Versioning
Indexing/search inside the word/pdf/text/... documents
I've tried doo for my mac, but it's still to buggy ...
Any suggestions?
You could run Alfresco or Nuxeo locally. Nuxeo has an OCR module that uses the tesseract OCR engine https://github.com/nuxeo/nuxeo-platform-ocr. They both support all of your list including the optional part.
However, these two systems are complex, and require a fair degree of configuration – hence, perhaps couldn't be described as 'simple'.
If you want something simple for Mac OS X, you could try the commercial offering called Paperless https://www.marinersoftware.com/products/paperless/. I haven't used the latest version, but it looks like they've added OCR support. This doesn't meet the free preference though!

I'm looking to (programmatically) convert a repository of Adobe Indesign template files (.indd) to something more easily manipulated by humans (ie, CSS/HTML files).
I'm more interested in an accurate conversion, than a fully readable one - the resulting files will be read by humans, and eventually made more readable.
Is there a tool or library I can use for this purpose?
Actually the only viable solution to convert from InDesign to html5 seems to be the "In5" plugin developed by Ajar Productions. I doubt it'll allow for bulk conversion but it seems to make a good job as regards accuracy.
Product and a detailed list of its features here: http://www.ajarproductions.com/pages/products/in5/

Can you suggest sites where I can generate dummy data based on my requirement for testing purposes of my project?
Note: I need a dummy data for usage of VMs and physical servers in terms of memory, CPU, disk, I/O utilization in percentage. Is there any site which provides utility to generate this kind of data?
Check out InfoChimps, they may have the sort of data your are after. But if you're just looking for numbers, it should be exceptionally trivial to just generate them yourself.
Maybe you can try http://www.generatedata.com/#generator
Obviously late to the discussion but in case anyone finds their way here. The baseball database contains some moderately large datasets (160,000+ records in the Fielding table, I believe).
Check out my MySQL Datagenerator. Perhaps that is what you are looking for...

I need something that takes a directory's contents and then proceeds to generate an RSS based on what is IN the files in the directory, meaning:
/myDir -ls
.
..
a.xml
b.xml
c.xml
d.txt
The mechanism I'm looking for would only look through the files with extension .xml, and would assemble their contents into one larger .xml (or .rss) file that it would spit back out, via HTTP.
You might like to have a look into ROME. It is a great utility to let you create, consume and manipulate ALL types of feeds be they RSS or ATOM of any version.
A quick article to get you started is ROME in a Day: Parse and Publish Feeds in Java.
