Experience

Distributed Read-write Lock Using Redis | Open-source RubyGem

https://github.com/potloc/potlock
POTLOCK is an advanced Redis-based concurrent read-write lock system designed to function seamlessly across different processes. It efficiently manages concurrent access by permitting only one reader or writer at a time. In instances where the lock is held, subsequent readers or writers must await their turn.

ISO Data Access and Scraper | Open-source RubyGem

https://github.com/metanorma/obp-access/
ISO project editors procure machine-readable informative clause content to initiate revision swiftly, bypassing the need for the intricate STS XML file.

Terminology users acquire precise term and definition information from a standardized source.

Bibliography users swiftly locate referenced documents pertinent to the standard in question.

Talawa | Open-source Music Sharing Platform

https://gitlab.com/talawa/website
