I was quite busy the past couple of days, but I finally managed to finish my mail-server migration.
And since I decided to also upgrade my old backup solution from the ancient times, I also wrote a guide for my new borgmatic based solution, which I now want to share with you guys.
I hope it helps some of you with your server backups.
I recently became interessted in learning about static site generators. So I decided to start a little 11ty blog, in which I teach people, who are new to self-hosting, how to securely set up their own server with Ubuntu and Docker.
For now, I've got my Beginners Guide series as well as a more detailed introduction to SSH and its features. I plan to eventually write down all I've learned about self-hosting in the past 20 years.
Hope it ends up being helpful for some of you.
EDIT (2025-10-28): Finally got around to get a proper domain and switched my blog to Hugo. Much easier to deal with and more capable imho than 11ty (and actually useful documentation as well). Oh and got rid of Netlify. Their 300 credit limit for a free deploy project is far too limiting if any deploy costs 15 credits...
Since switching to Mac / Apple Sillicon last year, I've had trouble with HDR videos on YouTube with Firefox.
For whatever reason, any HDR video will look super bright on Firefox. This problem only exists on Firefox. I've never had it with Safari or chromium-based browsers.
Here is a side-by-side comparison of how a test video looks. Sorry for the photo but the screenshot utility wouldn't capture the problem.
I've been searching the webs for a while but so far I could not find a bug report or anything related to this specific problem. Maybe someone else has had similar experiences and can help me with fixing it. I really don't want to have to switch to another browser whenever I come across an HDR video.
