Take a gem file that builds an extension and create a binary gem (useful for production servers without a build chain, Amazon EC2, etc).

GemExefy is RubyGems plugin aimed to replace batch files (.bat) with executables with the same name. This gem will work only on RubyInstaller Ruby installation and it requires RubyInstaller DevKit. Reason for such replaceming batch files with executable stubs is twofold. When execution of batch file is interrupted with Ctrl-C key combination, user is faced with the confusing question "Terminate batch job (Y/N)?" which is avoided after replacement. Second reason is appearance of processes in Task manager (or Process Explorer). In the case of batch files all processes are visible as ruby.exe. In order to distinguish between them, program arguments must be examined. In addition, having one process name makes it hard to define firewall rules. Having executable versions instead of batch files will facilitate process identification in task list as well as defining firewall rules. Moreover it makes it possible to create selective firewall rules for different Ruby gems. Installing Ruby applications as Windows services should be also much easer when executable stub is used instead of batch file.

FIX (describe your package)

A fork of gem-shut-the-fuck-up that provides configurable silencing of post-install-messages.

Are your gems taking up too much disk space? Documentation got you down? Comments stuck in your craw? Tests taking too much space? Fix all that by with <tt>gem tldr</tt>. I know that disk space is at a premium these days with an introductory netbook or a small AWS EC2 instance containing a mere 160GB. <tt>gem tldr</tt> removes the test directory, build artifacts like .c and .h files, comments in your ruby source files and comments in your ruby source.

Provides the ability to graph the dependencies of a given installed gem. Uses a similar approach to DepGraph, but finer-grained; graphs dependencies only for the named gem(s), rather than for all installed gems at once.

Map addresses to latitude and longitude using geocoder.us

GeoHash Gem for Ruby (c) 2008 David Troy dave@roundhousetech.com Geohash is a latitude/longitude encoding system invented by Gustavo Niemeyer when writing the web service at geohash.org, and put into the public domain. Geohashes offer properties like arbitrary precision, similar prefixes for nearby positions, and the possibility of gradually removing characters from the end of the code to reduce its size (and gradually lose precision). See these resources online: http://geohash.org http://en.wikipedia.org/wiki/Geohash http://openlocation.org/geohash/geohash-js (javascript implementation and demo)

GeoHash - encode, decode, neighbors

This GeoHex Ruby gem can convert latitude/longitude to GeoHex code each others. * Encode from latitude/longitude to GeoHex code to an arbitrary level of precision * Decode from GeoHex code to latitude/longitude and level of precision

Tool for spidering websites/blogs, extracting geodata from specific pages. Starting at a base URL, it will spider every page underneath, returning pages which have a URL that matches a desired pattern. The typical use case is spidering an entire blog for posts which contain geodata. Different methods for extracting geodata can be used. It currently supports UK postcodes and the abbr design pattern geo microformat &lt;http://microformats.org/wiki/geo&gt;. It is current in use behind the scenes of the Geoblogomatic &lt;http://www.geoblogomatic.com&gt;.

gephi_keeper is a Ruby conversion gem that links YourTwapperKeeper (http://your.twapperkeeper.com/) to Gephi (http://www.gephi.org) by converting JSON output from YTK to Gephi's GEXF format. YourTwapperKeeper is a self-hosted service that archives tweets. Gephi is a graph visualization tool. YTK exports the archived tweets in a number of formats, one of which is JSON. The JSON files produced by YTK are converted by gephi_keeper into Gephi-readable GEXF files. The GEXF files can then be processed by Gephi to produce colorful graph representations of Twitter output.

Vlad the Deployer is pragmatic application deployment automation, without mercy. Much like Capistrano, but with 1/10th the complexity. Vlad integrates seamlessly with Rake, and uses familiar and standard tools like ssh and rsync. Impale your application on the heartless spike of the Deployer. == FEATURES/PROBLEMS: * Full deployment automation stack. * Turnkey deployment for mongrel+apache+svn. * Supports single server deployment with just 3 variables defined. * Built on rake. Easy. Engine is small. * Very few dependencies. All simple. * Uses ssh with your ssh settings already in place. * Uses rsync for efficient transfers. * Run remote commands on one or more servers. * Mix and match local and remote tasks. * Compatible with all of your tab completion shell script rake-tastic goodness. * Ships with tests that actually pass in 0.028 seconds! * Does NOT support Windows right now (we think). Coming soon in 1.2.
