Setting up OERu-style virtual Ubuntu 20.04 or 22.04 server for Docker Compose

Here at the OER Foundation, where we build and maintain the computer services used by the OERu, its learners, and its educators around the globe, we've come up with a tech process that seems to work very nicely, with minimal cost and maintenance overhead. It involves setting up hosting infrastructure to adhere to some conventions that have emerged over time (and are subject to change if we identify better ones).

Setting up your own BitWarden password manager and VaultWarden sync server

One of the key requirements of pursuing Good Digital Hygiene is using strong passwords, and a different strong password for every application. This is relatively easy to do in theory, with the aid of clever software, but it's something desperately few people do well in practice. I'm going to explain how I've addressed this issue of digital hygiene for myself, and how you can do it for yourself, and your entire family, social circle, or community.

Configuring a Linux server to send email via the Postfix SMTP server using an external authenticating SMTP host

Just about any and every server needs to be able to send email - whether it's end-user-email, like password recovery services for a website to emails to system administrators reporting on the status of system backups and errors. The problem is that it's non trivial (understatement) to set up a mail server properly.

2020 OERF Open Technology Overview

As a matter of principle, the OER Foundation makes use of Free and Open Source Software (FOSS) wherever possible. Partnering with the Foundation provides an opportunity to share the experience of an organisation with hands-on experience in hosting all its technology infrastructure using FOSS.

The foundation has implemented a component-based approach selecting “best-of-breed” open technologies for assembling the OERu’s Digital Learning Environment (DLE) rather than providing learning materials through a single application like a Learning Management System (LMS).
