Postmortem: a Mastodon outage, Backup restore and preventive Maintenance


After reading about Mastodon UI theming options, I decided to follow the directions from the TangerineUI-for-Mastodon project to get another look’n’feel on my instance. The directions were pretty clear and short, so I went for them. But something failed during assets compilation process. And my Mastodon instance got wrecked. As a personnal “challenge”, I decided I would write a software post-mortem about this event. The end of the document will also summarize actions that were taken during post-backup-restoration maintenance phase.

Self-hosting Pixelfed on OpenBSD


In case you don’t already know, Pixelfed is a media sharing oriented solution that federates with Fediverse using the ActivityPub . And I like it also because it is based on PHP. This makes it quite simple to be hosted on OpenBSD. And here’s how I do this.

Self-Hosted SearXNG instance on OpenBSD


Some time ago, I discovered and used searx on OpenBSD . This worked quite well but there were a few annoying bugs that I couldn’t solve. Mainly using OpenSearch with Firefox and timeouts with some Big Tech search engines. After struggling enough, I decided to switch to SearXNG . It has some cons compared to SearX but, regarding my needs and beliefs, the pros win.

Multiboot Microsoft Windows, OpenBSD and Slackware Linux


I got a refurbished Lenovo ThinkPad X1 Carbon Gen 10 and I’m not really happy with how the fan is managed by OpenBSD. Plus, the ThinkPad A485 running Windows for $WORK has been freezing quite a few times recently. So I decided I could try using a single ThinkPad for both $WORK and $HOME using different Operating Systems. I recently loved Slackware Linux again and wished I could use it too on that machine. So this is how I configured a multiboot environnement on the ThinkPad with Microsoft Windows 11, OpenBSD 7.3 and Slackware Linux 15.0. Note that I will encrypt as much storage as possible using the various available OS technologies.

Self-Hosted Bookmarks using DAV and httpd on OpenBSD


I’ve long time used NextCloud and the floccus iOS App and Firefox plugin to store, manage and use my bookmarks. In reality, I don’t use the NC interface. I only use floccus ; and it works really well. In my journey to quit NextCloud, the only acceptable option to keep using floccus was getting a DAV self-hosted share. But, AFAIK, httpd(8) does not provide a DAV feature (yet?). I already use Baikal to self-host my calendars and addressbooks and it’s working great. So here’s a quick’n’dirty way to provide DAV using OpenBSD’s httpd(8) and sabre/dav.
