For relatively lightweight applications that are either in development, or single user, or have limited requirements for concurrency and massive data sets, SQLite is a superb, full-function, but compact, almost ubiquitous database (it's used on every mobile device, for example).

Update 2023-06-14: Here's a new tutorial for Ubuntu 22.04! Consider this older tutorial obsolete (but possibly helpful for people with older systems?)

With the recent release of Rocket.Chat 1.0.x (after a couple years undergoing development at a fairly blistering pace), it's time for many of us to upgrade!

Previously, I showed how to install Rocket.Chat via Docker Compose but that was a much earlier version of Rocket.Chat and version 3.4 of MongoDB, which is now quite old (by FOSS standards at least). And it turns out upgrading everything has a few gotchas, so here's how I managed to do it.

Update 2021-11-08: this post is now getting a bit long-in-the-tooth, and I need to update it to use up-to-date components. It might still be useful to folks, but use it with caution. Also, please note, we're using NextCloud with OnlyOffice (the open source community edition) these days. Update 2023-06-14: Here's a new tutorial for Ubuntu 22.04!

Not long ago, Mastodon, an open source, federated alternative to the proprietary network-effect wunderkind, Twitter, came out of no where.

A few months back, I posted instructions on deploying Rocket.Chat and Wekan instances (and their mutual dependency, MongoDB) individually. Since then, I've spent some time with Docker Compose, a set of scripts which help you to define, build, and manage a set of Docker containers. Docker Compose is a thing of beauty. This is the way I now deploy Rocket.Chat, Wekan, and MongoDB together.

Our approach to technology here at the OERu is inspired by the UNIX tool philosophy which can be summarised as follows:

"create simple tools that do one job well, and make it easy to combine them to work together"

At the OERu we have two separate instances of market category leading Discourse Forum: one for OER partner and contributor collaborators and the other for learners. These days, online forums are seen as a bit old-school: fuddy-duddy. From my point of view, however, Discourse is "Forum-NG" (a Next Generation forum).

Mautic is an open source marketing automation web application.

Rocket.Chat is a modern, open source messaging application which is functionally similar to a popular (and heavily marketed) proprietary tool called Slack.
