KUtil provides simple utility methods, such as file helpers, data object helpers and more.
A few CLI and general utilities. Includes a numbered-menu select loop utility, a ANSI formatting escape code handler, a text-based histogram maker, k-means and n-means (k-means with minimum optimal k) calculators, various collection utility methods, and a utility for using OptionParser with less code.
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.
Sym is a ruby library (gem) that offers both the command line interface (CLI) and a set of rich Ruby APIs, which make it rather trivial to add encryption and decryption of sensitive data to your development or deployment workflow. For additional security the private key itself can be encrypted with a user-generated password. For decryption using the key the password can be input into STDIN, or be defined by an ENV variable, or an OS-X Keychain Entry. Unlike many other existing encryption tools, Sym focuses on getting out of your way by offering a streamlined interface with password caching (if MemCached is installed and running locally) in hopes to make encryption of application secrets nearly completely transparent to the developers. Sym uses symmetric 256-bit key encryption with the AES-256-CBC cipher, same cipher as used by the US Government. For password-protecting the key Sym uses AES-128-CBC cipher. The resulting data is zlib-compressed and base64-encoded. The keys are also base64 encoded for easy copying/pasting/etc. Sym accomplishes encryption transparency by combining several convenient features: 1. Sym can read the private key from multiple source types, such as pathname, an environment variable name, a keychain entry, or CLI argument. You simply pass either of these to the -k flag — one flag that works for all source types. 2. By utilizing OS-X Keychain on a Mac, Sym offers truly secure way of storing the key on a local machine, much more secure then storing it on a file system, 3. By using a local password cache (activated with -c) via an in-memory provider such as memcached, sym invocations take advantage of password cache, and only ask for a password once per a configurable time period, 4. By using SYM_ARGS environment variable, where common flags can be saved. This is activated with sym -A, 5. By reading the key from the default key source file ~/.sym.key which requires no flags at all, 6. By utilizing the --negate option to quickly encrypt a regular file, or decrypt an encrypted file with extension .enc 7. By implementing the -t (edit) mode, that opens an encrypted file in your $EDITOR, and replaces the encrypted version upon save & exit, optionally creating a backup. 8. By offering the Sym::MagicFile ruby API to easily read encrypted files into memory. Please refer the module documentation available here: https://www.rubydoc.info/gems/sym
