Reef is a form generator written in PHP. It provides functionality to let your users build forms that can in turn be filled in by other users. It provides support to create, modify and delete forms. Forms can also be modified after submissions have been received. It is framework agnostic, in the sense that Reef is not built on top of or using a PHP framework. Hence, it can be used in combination with any framework.
 
Users can build forms using a drag and drop user interface. The forms and submissions are stored in your database using PDO. You can generate HTML code for displaying submissions, and also generate a CSV file containing all submissions.

Websockify is a WebSocket to TCP proxy/bridge. This allows a browser to connect to any application/server/service. Implementations in Python, C, Node.js and Ruby. websockify just translates WebSockets traffic to normal socket traffic. Websockify accepts the WebSockets handshake, parses it, and then begins forwarding traffic between the client and the target in both directions.

Fully asynchronous C implementation of the Raft consensus protocol. The library has modular design: its core part implements only the core Raft algorithm logic, in a fully platform independent way. On top of that, a pluggable interface defines the I/O implementation for networking (send/receive RPC messages) and disk persistence (store log entries and snapshots).

River is a fast and reliable background jobs in Go. River jobs never run before your transaction completes, and are never lost. River supports Transactional enqueueing, This model avoids several common failure modes of background jobs in a distributed application.
One of the biggest benefits of River is that jobs can be enqueued transactionally and atomically along with other database changes. Once a job is committed to the database, River will not lose track of it and will ensure that it is executed. When River jobs encounter an error or other failure, they are automatically retried after a delay.&nbsp;
River supports batch inserts, wherein many jobs are inserted at once using Postgres' COPY FROM protocol for optimal performance. If a worker recognizes that a job will never succeed, it can be cancelled permanently. It also provides an interface to handle errors and panics for custom application telemetry and to provide execution feedback.
Jobs are worked according to assigned priority, important jobs are processed first. Each named queue is processed independently and won't block other queues. It does graceful shutdown, Waits for active jobs to complete before exiting.

A distributed &quot;no single point of failure&quot; service directory of SOA services which allow clients to easily manage(find, use, publish, monitor, deploy) their services. By using it you increase the number of hot deployments, decrease server load on your services, increase availability of your service response times by using it's internal auto load balancing mechanism. Service repository stores the information about your service. Clients will communicate the repository and fetch the information about your service and then connect using the URL. This avoids the hard coded dependencies to (web/rest)services.
