    redlock-rb

    Redlock is a redis-based distributed lock implementation in Ruby

    Distributed locks are a very useful primitive in many environments where different processes require to operate with shared resources in a mutually exclusive way.

    There are a number of libraries and blog posts describing how to implement a DLM (Distributed Lock Manager) with Redis, but every library uses a different approach, and many use a simple approach with lower guarantees compared to what can be achieved with slightly more complex designs.

    This is an implementation of a proposed distributed lock algorithm with Redis. It started as a fork from antirez implementation.

    postgraphile-plugin-connection-filter

    Filtering on PostGraphile connections

    Adds a powerful suite of filtering capabilities to a PostGraphile schema.

    Warning: Use of this plugin with the default options may make it astoundingly trivial for a malicious actor (or a well-intentioned application that generates complex GraphQL queries) to overwhelm your database with expensive queries. See the Performance and Security section below for details.

    py_cui

    A python library for intuitively creating CUI/TUI interfaces with widgets, inspired by gocui.

    py_cui is a python library meant to simplify writing command line user interfaces in python. It relies on curses for terminal rendering, which is traditionally a unix-specific, however, you may use the windows-curses module to run py_cui on windows.

    The main advantage py_cui has over typical text-based user interface builders is that it relies on widgets and a grid layout manager like most traditional graphical user interfaces. You may define a grid size, and then drop predefined widgets onto it into specific grid locations. Widgets can also be stretched accross multiple grid rows and columns. If you’ve ever made a Tkinter GUI, you will feel right at home.

    If you would like to contribute, feel free to make an issue or pull request after reading through the CONTRIBUTING.md file.
