I need to port the deflate/inflate algorithm used in the png IDAT chunk, with CM=8.
I read the documentation on how it works the zlib and deflate algorithm for compression but probably it will be better for me to follow the steps already done by someone else more experienced than me for the porting.
Therefore I'm looking for the easiest source code for the implementation of inflate/deflate. I can read C codes and similar.
Any recommendation?
Thanks.
zlib provides some examples:
"puff" is a simple C implementation of DEFLATE, that's provided with zlib in its "contrib" directory. puff.c doesn't use zlib, and has about 875 lines, mostly comments.
zlib also provides a simple implementation called "zpipe.c", which is in the "examples" directory, but you might not want that because zpipe depends upon zlib (since it's an example of how to use zlib).

I have created one library, and now I want to have its documentation, so Is there any document generator available? If yes, What I have to keep in mind while generating documents.
http://www.doxygen.nl/
Doxygen is probably the most widely used option. Because it's not just for ObjC (doxygen supports many other languages), the development is lively and the community quite strong. HeaderDoc (now an open source project), by comparison appears to have largely stagnated. HeaderDoc only produces HTML output, while doxygen also produces PDF, LaTeX and many other output forms besides HTML. Even seems to recommend doxygen, with this guide to automatically producing documentation sets, compatible with 's help viewer, from within your build process.
It's worth noting that doxygen can read HeaderDoc-style comments, so you can write your documentation in HeaderDoc style and decide later whether to produce the final output using doxygen or HeaderDoc.

I am generating large PNG files from a Scala program. Currently, I am doing it the same way I would do it in java. I am creating a new BufferedImage and setting each pixel to the correct color. This works fine, but I am wondering if there are any good libraries for working with images in Scala? I am looking for something like Ruby's RMagick library.
Take a look at https://github.com/sksamuel/scrimage (Disclaimer: I am the author)
This is an open source Scala image library that essentially wraps java.awt Image operations in a nicer API as well as providing easy methods for operations like fitting to a given size, etc.
Maybe JMagick? Take a look here, it's a native interface between ImageMagick and Java exactly like RMagick..

I am going to need to do some development with Eclipse JDT while on holiday. I will be off-line for the most of the time and therefore I will not be able to access the [Eclipse JDT API documentation] (edit : link is now dead) on the Web. I can't find a link to download the documentation in ZIP or PDF or, best of all, CHM format. Does anyone have a copy? Could you please provide a download link to it?
Do you think I should use HTTRack to simply mirror the above-mentioned website? I would really rather not. CHM is rather convenient for exploring any kind of API documentation. Anyone differs in opinion?
Just download and unpack this one http://repo1.maven.org/maven2/org/eclipse/jdt/doc/isv/3.2.1-r321_v20060907/isv-3.2.1-r321_v20060907.jar

I'm looking for recommendations on an Objective-C library for AES-256 encryption in CTR mode. I have a database full of data encrypted with another library using CTR and seems the included CCCrypt only supports ECB or CBC with PKCS#7.
Any idea on the best portable library I should use? I'm not looking to port the original implementation as I don't have the required knowledge in cryptography and hence, that's-a-bad-idea (tm).
Thanks!
You should be able to implement this using OpenSSL. It is not Objective C, but rather "plain" C code, but since the built-in encryption algorithms in the iPhone also rely on plain C, this should hopefully not make that big a difference.
There is a tutorial on The Rare AiR on how you can compile the OpenSSL library for iPhone.
Hope this helps,
Claus

Can anyone point me to some good Open Source web interface for VCS (version control system) written in Perl?
Something well written, so I can examine the code and steal the best parts (or organization) for gitweb. Preferably something without tons of external dependences not available in (extended) Perl core.
I haven't looked at the source code of SVN::Web, so I can't tell you if it's well written, but I sure like to use it. Here is a list of the dependencies, and you can see it in action.
Have you has a look at CvsMonitor? Its a little old but its a perl web interface into CVS.
