Awesome Data Science with Ruby

Links and Resources for Data Processing and Analysis in Ruby

Data Science is a new
“sexy” buzzword without specific meaning but often used to substitute
Statistics, Scientific Computing, Text and Data Mining and
Visualization, Machine Learning, Data Processing and Warehousing as
well as Retrieval Algorithms of any kind.

This curated list comprises awesome tutorials, libraries,
information sources about various Data Science applications using
the Ruby programming language.

A lot of useful resources on this list come from the development by
The Ruby Science Foundation, our contributors and
our own day to day work on various data intensive applications.
Read why this list is awesome.

Wait but why?

There are a lot of software lists with tools related to the Data Science.
There are a couple of lists with Ruby related projects. There are no lists of
only working and tested software with documented scope. We’ll try to make one!

What is awesome? Awesome are documented, maintained and focused tools.

Can something turn not awesome at a point? Yes! Abandoned projects with broken
dependencies aren’t awesome any more! They leave this list.
