  valvat

  Validates european vat numbers. Standalone or as a ActiveModel validator.

  Valvat supports validating VAT-IDs from the UK by syntax, checksum and using the HMRC API v2.0. Validation against the VIES web service stopped working early 2021.

  Sadly with the deprecation of the HMRC API v1 on January 2025 there is no open accessible web service to validate UK vat numbers anymore. To use the current v2 of the HMRC API you will need to create an account on the HMRC Developer Hub and then apply for production credentials. The second step is a little bit more involved and can take up to ten business days. See the configuration section below how to use valvat with your HMRC authentication credentials.

  Northern Ireland received its own VAT number prefix - XI which is supported by VIES web service so any XI-prefixed VAT numbers should be validated as any EU VAT number.

  drb

  Distributed object system for Ruby

  dRuby is a distributed object system for Ruby. It allows an object in one Ruby process to invoke methods on an object in another Ruby process on the same or a different machine.

  The Ruby standard library contains the core classes of the dRuby package. However, the full package also includes access control lists and the Rinda tuple-space distributed task management system, as well as a large number of samples. The full dRuby package can be downloaded from the dRuby home page (see References).

  For an introduction and examples of usage see the documentation to the DRb module.

  openfoodnetwork

  Connect suppliers, distributors and consumers to trade local produce.

  The Open Food Network is an online marketplace for local food. It enables a network of independent online food stores that connects farmers and food hubs (including co-ops, online farmers markets, independent food businesses, etc) with individuals and local businesses. It gives farmers and food hubs an easier and fairer way to distribute their food.

  Supported by the Open Food Foundation and a network of global affiliates, we are proudly open source and not-for-profit - we’re trying to seriously disrupt the concentration of power in global agri-food systems, and we need as many smart people working together on this as possible.

  We’re part of global movement - get involved!

  • Join the conversation [on Slack][slack-invite]. Make sure you introduce yourself in the #general channel and join #dev for all tech-related topics.
  • Head to https://openfoodnetwork.org for more information about the global OFN project.
  • Check out the User Guide for a list of features and tutorials.

  kitchenplan

  Kitchenplan is a small tool to fully automate the installation and configuration of an OSX workstation (or server for that matter) using Chef. But while doing so manually is not a trivial undertaking, Kitchenplan has abstracted away all the hard parts.
