When looking for a simple groovy mode plugin for emacs to get indenting and some form of syntax highlighting, I found 3 version on the groovy website.
This page is excellent at giving the overview and some down in the weeds details, however is a bit skimpy on why to choose one over the other.
There is Jeremy Rayner's groovy-mode.el which isn't painful
There is Russel Winder's identically named groovy-mode.el which is based on cc-mode.
There Stuart Clayman inferioir groovy mode inf-groovy.el
Currently I am drawn toward Jeremy's plugin, but I feel that being not painful is a poor reason to choose one over the others.
I'd like to know which ones are recommended or which ones are to be avoided?

Things changed a bit since ataylor's answer: now (March 2017) the official Groovy website links to Emacs-Groovy-Mode which combines Russel Winder's and Stuart Clayman's work.
As we may expect, the repo is available on Github.

I use Jeremy Ranyer's groovy-mode.el for the sole reason that it worked better with my code then Russel Winder's version, at the time I tested them.
Here's a small modification I've added to Rayner's that fixes some problems (the elvis operator, if I recall correctly):
(defconst groovy-block-mid-re
"need something here or it blows up"
)

I remember seeing something of that sort a couple of years ago but I can't recall what it was? I'm not searching for conqueror which is an external web browser.
Does any of you about such a browser?
w3m can be run in Emacs buffer as well through emacs-w3m. Note that contrary to Emacs/W3, this is not a pure browser implemementation in Emacs Lisp, but an interface to a standalone tool, and in fact it's not graphical as well.
Some day http://www.emacswiki.org/emacs/EmacsXWidgets work will be finished and hackers will be able to surf the interwebs conviniently without leaving Emacs at all since modern browsers will merge with their notorious ancestor.
I don't think it's being actively developed, but you might try EZBL:
github: https://github.com/haxney/ezbl
emacswiki: http://www.emacswiki.org/emacs/ezbl
I think you might be looking for Emacs/W3 but as it stated in the corresponding wikipedia article, it is now somewhat obsolete. A rewrite is pending, but I don't know about its status.
I can suggest EXWM - Emacs window manager. You can use any web browser you prefer with it. It works on linux only. You can use it alongside current DE or as a separate DE (in which case you may be interested in making sort of menu bars etc - just google how). Personaly I prefer Manjaro-KDE setup with EXWM running alongside KDE. You can read HN (Hacker News), reddit (r/emacs) for more detailed explanations and ideas. E.g. people can use firefox, chrome, nyxt (next), qutebrowser, eaf-browser in exwm with no problem. If you want to go deeper and integrate your gui browser with emacs like here you may consider nyxt, eaf-browser (readily integrated history), xwidget-webkit.
Firefox with KDE-browser integration and other hacks is also possible (see ryan rix workflow)

I was wondering if anyone can recommend any GUI/portal/platform/application that shows code revisions. I'm using subversion with my eclipse and wonder if there's something nice such as trac to see the changes.
Thanks

I've been using WebSVN and it works great. I've put it at the same host as my repository and access it through standard apache. WebSVN is free.
Then there is FishEye from Atlassian. It's not free but I don't doubt it's one of the best ones available.
What about good old subclipse? Not only it shows revisions, but also it's a great implementation of subversion client for eclipse with such functionality as: commit, update, branch, merge, etc. Not mentioning extended visualization capabilities. It seems that you do not use subclipse while you definitely should.

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.

The question says it all: I'm looking for working, open source, implementations of algorithms (or derivatives there of) initially described in the Boids paper.
It looks like most of the code out there was written before "Open Source" really meant anything. I asked Mr Google:
Craig Reynolds's Boids page has a bunch of links for various languages and some mostly-original Lisp. Embedding a Lisp interpreter should not be that hard.
Christopher Kline, C++, Not-For-Profit. Licence terms for commercial apps negotiable with the author.
Tom Bak, Thong Chau, Visual C++/OpenGL/GLUT, no licence. You could try contacting them.
Robert Platt, VC++/D3D, no licence. You could try contacting him too.
You're unlikely to find anything specifically "for the iOS" (or even written in Objective-C), but C and C++ versions should be easy to port. .NET versions should be easy enough to run using MonoTouch.
This might help: Chapter from Killer game programming in Java about Flocking Boids

I notice there is an sbaz tool that seems to have similar functionality to the ruby gem tool but I don't see any community site like gemcutter.org / rubygems.org. Is there something like this around.
There are 1084 repositories on github with scala in them. I'm surprised I can't find some centralized package management utility. Perhaps I'm just googling the wrong keywords.
The closest equivalent is probably http://scala-tools.org which maintains a Maven (ivy, sbt, etc) repository of most of the best-known packages.
Scala Tools appears to no longer be functional as of this writing. It says:
We are no longer providing any support for scala-tools.org.
Instead, it is suggested to use https://oss.sonatype.org/
As Kris said, http://scala-tools.org is the closest thing so far. We're working on improving the site, and will be enabling "static project sites" shortly. There's also http://implicit.ly/ which aims to be the standard new source for published releases.
