Roman Numerals in Clojure

I saw this post on Roman Numerals in Clojure:

http://www.jayway.com/2012/08/04/a-decimal-to-roman-numeral-converter-in-just...

This is the sort of little programming problem that can stop useful work dead in its tracks. Here's my shot at the problem. I think it reads better in that the recursion just deals with the numbers and the Roman numeral strings are mapped latter. It's also a bit more efficient in the way it tests against the Roman "bases" (as I call them). There's no need to retest against a high base once your interim value has gone below that mark. In any case, my version is quite a bit faster than the other solution in my micro-benchmarks.

Rich JavaScript Applications – the Seven Frameworks (Throne of JS, 2012)

Nice summary with links to a bunch of JS app libraries and frameworks:

http://blog.stevensanderson.com/2012/08/01/rich-javascript-applications-the-s...

For many web developers, it’s now taken for granted that such client-side frameworks are the way to build rich web apps. If you’re not using one, you’re either not building an application, or you’re just missing out.

Journey Through The JavaScript MVC Jungle

http://coding.smashingmagazine.com/2012/07/27/journey-through-the-javascript-...

Fortunately there are modern JavaScript frameworks that can assist with bringing structure and organization to our projects, improving how easily maintainable they are in the long-run.

These modern frameworks provide developers an easy path to organizing their code using variations of a pattern known as MVC (Model-View-Controller).
