JavaScript Views Can Be Logical

http://metaskills.net/2012/05/22/view-controller-patterns-with-spine-js-and-spacepen/

Yea, about JavaScipt, but yesterday DHH was tweeting again about pushing HTML back from AJAX responses since they do not like logicless templates. But they do not have to be. Here is an article called View Controller Patterns With Spine.JS & SpacePen that explores Apple design patterns for ViewController that play out nicely with Spine.JS and SpacePen. Perhaps these methods can be applied to other MV* JavaScript frameworks?

This blog post describes how to easily rotate images in any angle and how to automatically rotate images left or right if the desired aspect ratio doesn’t match the original image. Image rotations can be mixed with any other Cloudinary’s image transformations. The results are cached and delivered through a fast CDN. Ruby on Rails sample code included.

A Library that allows calculation of probabilities and properties of binomial experiments

http://mkonutgan.github.com/bernoulli/

I recently needed to do a few calculations of properties of binomially distributed random variables for my statistics class. Naturally, I wrote the code in Ruby and found it pretty useful, so I refactored the relevant parts and released a gem: bernoulli. The library is quite stable and extremely simple. All available methods are documented and a few example usages are given on the homepage.
