"What is fpm? It helps you build packages quickly (Packages like RPM and DEB formats). The goal of FPM is to be able to easily build platform-native packages; Creating packages easily (deb, rpm, etc), Tweaking existing packages (removing files, changing metadata/dependencies), Stripping pre/post/maintainer scripts from packages."

"Scripting Languages: PHP, Perl, Python, Ruby. A side-by-side reference sheet."

"Resque is a great implementation of a job queue by the people at github. It's written in ruby, which is great, but I primarily work in python. So I took on the task of porting over the code to python and PyRes was the result"

"This is a Ruby translation of Zed Shaw's popular book Learn Python The Hard Way, 2nd Edition. The prose in this translation is nearly 100% identical to the Python version with the exception of a few paragraphs that have been modified to be relevant to Ruby. All of the code exercises and required libraries have been completely adapted for Ruby."

"Resque (pronounced like "rescue") is a Redis-backed library for creating background jobs, placing those jobs on multiple queues, and processing them later."

"Docsplit is a command-line utility and Ruby library for splitting apart documents into their component parts: searchable UTF-8 plain text via OCR if necessary, page images or thumbnails in any format, PDFs, single pages, and document metadata (title, author, number of pages...)"

"... is a collection of tools to download, clean, process, and package datasets from a variety of sources (HTML, RSS, XML, CSV, &c) into a variety of formats (XML, CSV, Excel, JSON, SQL, YAML, &c). Interacting with IMW is as simple as creating a YAML file which describes the workflow involved in processing the data and feeding it to the imw command line program."

"OmniAuth is a Rack-based authentication system that abstracts away the gritty, difficult parts of external authentication without assuming anything about what you actually want to do with that authentication information. What does this mean for you? This means that you can make your app authenticate through Twitter, Facebook, LinkedIn, Google Apps, GitHub, Foursquare, and more and then have complete control from there."

"In the days the news are about instant searches and auto complete, Salvatore Sanfilippo (@antirez) shows how to use Redis sorted sets and corresponding commands (ZRANGE, ZRANK) to implement autocompletion."

Fast Artificial Neural Network Library is a free open source neural network library, which implements multilayer artificial neural networks in C with support for both fully connected and sparsely connected networks. Cross-platform execution in both fixed and floating point are supported. It includes a framework for easy handling of training data sets. It is easy to use, versatile, well documented, and fast. PHP, C++, .NET, Ada, Python, Delphi, Octave, Ruby, Prolog Pure Data and Mathematica bindings are available.

MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small. Typical small integer (like flags or error code) is saved only in 1 byte, and typical short string only needs 1 byte except the length of the string itself. [1,2,3] (3 elements array) is serialized in 4 bytes using MessagePack.

Chef is a systems integration framework, built to bring the benefits of configuration management to your entire infrastructure. With Chef, you can:

* Manage your servers by writing code, not by running commands. (via Cookbooks)
* Integrate tightly with your applications, databases, LDAP directories, and more. (via Libraries)
* Easily configure applications that require knowledge about your entire infrastructure ("What systems are running my application?" "What is the current master database server?")
