I found several JavaScript testing frameworks with a quick Google search: Jasmine, jsUnity, JSpec, YUI Test, JsUnit, QUnit
I'm sure that this is by no means an exhaustive list.
Has anyone written CoffeeScript koans in one of these frameworks, similar to the EdgeCase ruby koans?
I really enjoyed going through them and going through the python-koans. Each exercise significantly improved my language comfort level, and I'm really hoping that similar exercises exist for CoffeeScript.

Did you try Googling "CoffeeScript Koans"? :)

(They're powered by Jasmine.)

I want to learn Perl and thought that the most of GNU Coreutils seems to be doing stuff which are well suited for the language. Is there any Perl implementation of it (at least the basic functionality) which I could look at for comparison?
In my experience, looking at code is the second best way to learn a language (after writing code). I'm interested both in quick-and-dirty implementations and clean code which covers edge cases as well.
For example, cat could be implemented as
alias cat='perl -Tpe "" --'
although there are some edge cases where it doesn't behave the same. And of course it ignores all flags.
This has already been done years ago: http://search.cpan.org/dist/ppt/

Does anyone know Emacs version of VimGolf? I can't find it. But there should be any site. I want to know how others use Emacs and learn more productive way. Thanks.
Is this what you're looking for?
Tim Visher has a series of videos on the subject. I guess this is most comprehensive resource you can find.
In the Irreal blog, you'll find many posts related to vimgolf in emacs, where readers post and compare their solutions.

I am pretty new to Scala and I think that the best way to learn a language is to learn from others. Is there any good scala open source project focusing on machine learning? Thanks a lot.
You should checkout Breeze, it has quite a few built in ML algorithms, though the documentation can be sparse, I would recommend looking at the source:
http://www.scalanlp.org/
That's not an OS project, but i just have to sugest you to watch the talk given by Christopher Severs and Vitaly Gordon on ScalaDays'13 on Machine Learning With Scala

I am looking out for a rule engine in perl.
Would like to know what are the features, that should be kept in mind related to the same.
Also the context is a travel domain and the business rule related to it.
Would appreciate your views on the same.
I believe your question is answered at http://www.perlmonks.org/index.pl?node_id=722668 and other places (google for Business Rule engine Perl). Some of the suggestions are:
PIE
Bricks (could not find anything beyond this one site)
VS::RuleEngine

I'm looking into frameworks for translation, and have been considering gettext. Because it's supposedly quite good, and lots of projects use it. Now I read part of the official manual, but it sucked. I kind of have an idea how it works now, but I have no idea where to get started.
In particular my project spans C++, Lua and Javascript, so I'd love to be able to unify the i18n with a single tool, but I'm also not having luck finding gettext good support for Lua or Javascript, are they supported, has anybody used gettext with these?
Thanks.
How about this tutorial? Another example is at O'Reilly.
