Ruby C extension to access temperature and humidity reading taken by the DHT-XX type sensors, see (http://www.adafruit.com/products/385)

The Diff Match and Patch libraries offer robust algorithms to perform the operations required for synchronizing plain text.

DiffSet contains a collection of data structures optimized to perform partial set subtractions

Ruby native extension for base32 encoding and decoding.

With marshalling of digest objects, it is possible to compute the digests over several executions by storing the marshalled object on file or database, this is handy for computing digests for large files that comes in parts.

A KangarooTwelve library that utilizes the XKCP package and can be optionally optimized during compile-time based on a target. It produces implementation classes that work on top of Digest::Base and conform with how Digest classes work.

Digest::SipHash is a class of message digest use algorithm SipHash.

Digest::StringBuffer is a class that subset of Digest::Instance.

Native implementation of Dijkstra algorithm for finding the shortest path between two vertices in a large, sparse graphs. Underlying algorithm is implemented in C using a priority queue. Edges are represented using linked lists rather than an adjacency matrix to reduce memory footprint when operating on very large graphs where the average number of edges between nodes is relatively small (e.g. < 1/10 the number of nodes). See https://en.wikipedia.org/wiki/Dijkstra's_algorithm for additional information.

To calculate the directory size

Ruby bindings for the disarm Rust core: TR39 confusable folding, bidi/zalgo/ zero-width neutralization, Unicode normalization, standards-based transliteration, slugification, and IDN/hostname spoof detection. The native extension wraps the pure-Rust core (no Python), so precompiled platform gems run without a local Rust toolchain.
