Hourly versioned MongoDB backup

Because the collaboration of an open community is its real history, I place a high value on backing up the Rocket.Chat servers I'm responsible for, and especially the data they generate, held in MongoDB files (on the host) managed by a MongoDB container.

To do that reliably, I have set up a bash script which does an hourly backup of all MongoDB "databases" and automatically maintains 24 hourly, 7 daily, 4 weekly, 12 monthly, and 7 yearly snapshots of the databases.

Upgrading RocketChat to 1.0.x and MongoDB to 4.0

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.

Democratising Higher Education with OERs & FOSS

Rather than write a slide-based presentation for the Open Education miniconf at Linux.Conf.AU 2019, I thought I'd try an approach that seemed to work quite well recently: write my presentation as a blog post and make it available for posterity, before and after. You can find this post quickly by going to oer.nz/lca if you want to look at it on your own device.

2018 update on the OERu Technology Stack

As I prepare for the 2018 OERu Partners' Meeting, I'm working how to convey the depth and breadth of the OERu open source technology stack - our infrastructure and applications - to our partners and other attendees.

Over the past year, we've had our first live OERu courses allowing learners to work towards a formal exit qualification (our "1st year of study"), and our infrastructure has worked as intended throughout, so I'm chalking that up as a win.

Insight: what does the Open Source Technologist at the OER Foundation do?

A few weeks ago, I got an unexpected (but very flattering!) request from a friend and colleague's son, Felix. He wanted to interview me about my work (at 11, he thinks he might want to become a software developer, too, when he's older) as material he could present at an up-coming PechaKucha session at his school... Wow, we didn't do PechaKucha when I was a kid :)
