The Lorax is a full diff and patch library for XML/HTML documents, based on Nokogiri. It can tell you whether two XML/HTML documents are identical, or if they're not, tell you what's different. In trivial cases, it can even apply the patch. It's based loosely on Gregory Cobena's master's thesis paper, which generates deltas in less than O(n * log n) time, accepting some tradeoffs in the size of the delta set. You can find his paper at http://gregory.cobena.free.fr/www/Publications/thesis.html. "I am the Lorax, I speak for the trees."

Erector is a Builder-like view framework, inspired by Markaby but overcoming some of its flaws. In Erector all views are objects, not template files, which allows the full power of object-oriented programming (inheritance, modular decomposition, encapsulation) in views.

You don't have to wait until Ruby 2.0 to get (named|keyword) arguments support. Arguments has been tested with Ruby 1.8.6 and ruby 1.9.1 and eventually will work with JRuby (if someone is interested in contributing, I guess is possible since merb-action-args works with JRuby)

Chimera is an object mapper for Riak and Redis. The idea is to mix the advantages of Riak (scalability, massive data storage) with Redis (atomicity, performance, data structures). You should store the bulk of your data in Riak, and then use Redis data structures where appropriate (for example, a counter or set of keys). Internally, Chimera uses Redis for any indexes you define as well as some default indexes that are automatically created. There's no built in sharding for Redis, but since it's only being used for key storage and basic data elements you should be able to go a long way with one Redis server (especially if you use the new Redis VM). !! Chimera is alpha. It's not production tested and needs a better test suite. !! !! It's also only tested in Ruby 1.9. !!

Generate a 4 word password from words of size 3-8 characters, with frequencies in the 30th-60th percentile. This range gives a nice set of uncommon but not completely alien words. $ chbs generate --verbose -W 3..8 -P 30..60 Corpus size: 6396 candidate words of 33075 total Entropy: 48 bits (2^48 = 281474976710656) Years to guess at 1000 guesses/sec: 8926 magnate-thermal-sandbank-augur With the --verbose flag, the utility will calculate a time-to-guess based on a completely arbitrary 1000 guesses/sec. If you'd like a more secure password, either relax the various filtering rules (-W and -P), add more words to the password, or use a larger corpus. By default we use the American TV Shows & Scripts corpus taken from Wiktionary. Others provided: * Project Gutenberg 2005 corpus taken from Wiktionary. * 1 of every 7 of the top 60000 lemmas from wordfrequency.info (6900 actual lemmas after processing) See http://xkcd.com/936/ for the genesis of the idea.

A java like Enum class for ruby. A while ago I was exploring Java, and came across the Enum class, which had some interesting functionality, and I decided that I would like something like it. Conceptually if you just need a unique identifier you may be perfectly happy using a :symbol, and that would likely be a simpler way of having a controll flag. However, if you want to have a set of unique identifiers that you can address, iterate over, assign properties to, etc, then this may be something you would be interested in.

forkify.rb makes it easy to process a bunch of data using 'n' worker processes. It is based off of forkoff and threadify by Ara Howard. It aims to be safe to use on Ruby 1.8.6+ and Ruby 1.9.1+
