Installing LimeSurvey with Docker on Ubuntu 16.04 with Nginx and Mariadb

LimeSurvey is an open source survery tool, functionally similar to far more heavily marketed proprietary tools like SurveyMonkey and Google Forms. It's a very mature, fully-featured system. You can either use the reasonably priced hosted service available on the LimeSurvey site, or you can host your own, holding your own data and collecting your own analytics if you prefer. The only cost of hosting your own is your time to set it up and any costs associated with your hosting environment (which, today, can be negligible).

WikiEducator Notes: OERu's course feed aggregation and messaging system

Here at the OERu, we provide a service, attached to all of our online courses (and available to all of our partners - or anyone else for that matter) which allows anyone involved in those courses to communicate with one another from any one of a dazzling array of online "places" with WikiEducator Notes (aka WEnotes). The entire system is free and open source software (FOSS). 

OERu MediaWiki to WordPress Snapshot Toolchain

One of the OERu's most compelling technological capabilities is the set of internally developed open source tools that allow us to automatically transform and inject a collection of MediaWiki content on WikiEducator (usually in form of micro-courses) making up a course into a mobile-friendly, easy-to-navigate WordPress site, usually situated on OERu's Course WordPress Multisite implementation.

Docker Compose: A better way to deploy Rocketchat, Wekan, and MongoDB

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.
