Aries Verifiable Credentials Registry (VCR), part of the Hyperledger Aries family of Digital Trust technologies, provides a searchable public directory based on Verifiable Credentials (VCs). It was historically known as both OrgBook (which is actually a deployment of Aries VCR) and Indy Catalyst. Aries VCR is actively developed by the British Columbia Government’s Digital Trust Team in Canada, and the most well-known live example is OrgBook BC. In an instance of Aries VCR, credentials can be issued from a variety of authorities about subjects in the instance. A core set of credentials are issued by an authority responsible for “creating” the subject. Other credentials can then be issued against the subject of these core credentials. All credentials are stored in a secure digital wallet and accessed via its website or the public API. This means an instance of Aries VCR can be an authoritative public registry of any referenceable information.

Users interact with D‑Wave quantum computers through a web user interface (UI), and through open-source tools that communicate with the Solver API (SAPI). The SAPI components are responsible for user interaction, user authentication, and work scheduling. In turn, SAPI connects to back-end servers that send problems to and return results from QPUs and additional solvers, which are located in different geographical regions (for example, North America or Europe).[1]

Shared API for binary quadratic models and samplers in D-Wave Ocean.

dwave-system is an API for easily incorporating D-Wave quantum computers as a sampler in the Ocean software stack, directly or through the Leap service’s cloud-based hybrid solvers. It includes DWaveSampler, a dimod sampler that accepts and passes system parameters such as system identification and authentication down the stack, StrideHybridSolver, for Leap’s Stride™ hybrid solver, and others. It also includes several useful composites—layers of pre- and post-processing—that can be used with DWaveSampler to handle minor-embedding, optimize chain strength, etc.

DSL RBI generator for Sorbet-typed Ruby applications.

The most popular tool for teams to coordinate mapping on OpenStreetMap. With this web application, an area of interest can be defined and divided up into smaller tasks that can be completed rapidly. It shows which areas need to be mapped and which areas need a review for quality assurance. You can see the tool in action: log into the widely used HOT Tasking Manager and start mapping. This is Free and Open Source Software. You are welcome to use the code and set up your own instance. The Tasking Manager has been initially designed and built by and for the Humanitarian OpenStreetMap Team, and is nowadays used by many communities and organizations.
