rails_code_auditor is a developer-friendly Ruby gem that automates the process of auditing your Rails codebase. It runs a suite of essential tools—including Brakeman, Bundler Audit, RuboCop, Rails Best Practices, Flay, Flog, and License Finder—and consolidates all outputs into a single readable report.

This gem implements the following random network generation models: Erdos-Renyi GNM and GNP, Watts-Strogatz, and preferential attachement. It also implements graph algorithms to study the randomly generated graphs.

A tool for analysis and visualization of projects written in Ruby

Stupid easy business analytics

This aims to provide similar features to access to Bugzilla through WebService APIs in Ruby.

ruby-mext: musical extensions for the Ruby language.

This is a simple machine learning library written in Ruby. It provides implementations of linear regression and multiclass perceptron and visualization and validation methods to verify results. Also included are helper methods to work with training and testing data.

Ruby Scientist and Graphics is a practical data science toolkit for Ruby. It includes a lightweight built-in DataFrame for loading, cleaning, and transforming data; quick descriptive statistics and correlations; charting via Gruff (bar and line); and simple ML utilities (linear regression and k-means)—all behind a small, unified, pandas-inspired API. Key features: - Load data from CSV and JSON. - Clean and transform (remove/add columns, handle missing values, limit rows). - Describe datasets and compute correlations quickly. - Create bar and line charts with customization options. - Train/predict with linear regression; cluster with k-means. - Save/load project state (data + trained model) and run simple pipelines. - Optional backend adapters (e.g., Rover) while keeping the same API. Ideal for analysts and developers who want to explore data in Ruby without relying on Python or R. Note: plotting via Gruff uses rmagick, which requires ImageMagick installed on the system.

== DESCRIPTION: rutemaweb is the web frontend for rutema. It can be used as a viewer for database files created with the rutema ActiveRecord reporter. It also provides you with some basic statistics about the tests in your database in the form of diagrams of debatable aesthetics but undoubtable value! == FEATURES/PROBLEMS: == SYNOPSIS: rutemaweb [results.db] and browse to http://localhost:7000 for the glorious view == REQUIREMENTS: * patir (http://patir.rubyforge.org) * activerecord (http://ar.rubyonrails.com/) * sqlite3 (http://rubyforge.org/projects/sqlite-ruby/) * ramaze (http://www.ramaze.net/) * ruport (http://rubyreports.org/) * acts_as_reportable * erubis * gruff/RMagick (optional, but needed if you want to see the statistics graphs)

Supplementary Gem to sql_tracker allowing you to compare query data bewteen files

Worked is really the simplest time recording (or tracking, whatever term you prefer) application that does all you need and nothing more (only `date >> file` is easier). It simply takes a time or a time range and an activity and appends it to a hidden file in the current directory. The use case is, that you have '.worked' files in the root directories of your projects, and before you finish your current work period, you probably commit something and you also record your time. Right now, the times are just recorded, no report generation yet.
