Tinode is a  Instant Messaging Server. It is not XMPP/Jabber. It is not compatible with XMPP. It's meant as a replacement for XMPP. On the surface, it's a lot like open source WhatsApp or Telegram. The goal of this project is to deliver on XMPP's original vision: create a modern open platform for federated instant messaging with an emphasis on mobile communication. A secondary goal is to create a decentralized IM platform that is much harder to track and block by the governments.

At a high level, Faktory is a work server. It is the repository for background jobs within your application. Jobs have a type and a set of arguments and are placed into queues for workers to fetch and execute.You can use this server to distribute jobs to one or hundreds of machines. Jobs can be executed with any language by clients using the Faktory API to fetch a job from a queue.
 
Faktory is a server daemon which provides a simple API to produce and consume background jobs. Here's the chatter to create and execute a background job. Jobs are a small JSON hash with a few mandatory keys. Producers PUSH a job to a queue. Consumers FETCH jobs from queues, process them and then either ACK (success) or FAIL the job. Faktory will store and re-enqueue failed jobs over time just as Sidekiq does (these are called "retries"). Networks fail and bugs happen, job retries are critical to a "self-healing" production environment. 
 
Many existing job systems provide no persistence or a simple binlog which can be replayed in case of crash. Faktory goes further and provides the same job persistence, state management and monitoring Web UI that Sidekiq does. It uses Facebook's high-performance RocksDB embedded datastore internally to persist all job data, queues, error state, etc. It exposes a Web UI (which is similar to Sidekiq's), allowing you to see the current state of your queues, jobs and workers.

The Database Lab Engine is an open-source experimentation platform for PostgreSQL databases. Instantly create full-size clones of your production database and use them to test your database migrations, optimize SQL, or deploy full-size staging apps.
 
Thin cloning is possible due to <a href="https://en.wikipedia.org/wiki/Copy-on-write" target="_blank" rel="noopener noreferrer">copy-on-write</a>&nbsp;capabilities provided by either&nbsp;<a href="https://en.wikipedia.org/wiki/ZFS" target="_blank" rel="noopener noreferrer">ZFS filesystem</a>&nbsp;or&nbsp;<a href="https://en.wikipedia.org/wiki/Logical_Volume_Manager_(Linux)" target="_blank" rel="noopener noreferrer">LVM2</a>. As an example, cloning of 10 TiB PostgreSQL database takes less than 2 seconds when a single user is using the Database Lab Engine instance, and up to 30 seconds when 15 users are working with it at the same time.
