As is trendy right now, I too took my repositories off of GitHub. The last piece was this website, which I hosted on GitHub Pages, but now runs on Oracle Free Tier. Not really sure this is better, but that’s what I’m trying for now and I can always move it somewhere else easily. I’m also self hosting Forgejo where I will be sharing my code from now on. 

It’s a shame we don’t have ubiquitous decentralized chat equivalent to email. I know Matrix and XMPP exist, but neither are complete enough. And they dont’t have a lot of users. 

Since Discord announced it will start asking users for age verification, I became obsessed with reading about alternatives to the platform. And there are a lot of them. As a self-hoster, I immediately thought of Matrix and XMPP. Both have their pros and cons and different implementations. 
 I was almost ready to pick one of them when I stopped and thought to myself, would I really use them?…

Seit etwa 2020 hat mich die Idee fasziniert, meinen eigenen Server zu betreiben – also die volle Kontrolle über Daten, Dienste und Medien zu haben. Vor allem auf Reddit, und dort besonders in den Communities r/selfhosted und r/homelab , habe ich immer wieder spannende Projekte gesehen. Lange blieb das für mich ein Traum – zu wenig Zeit, zu wenig Geld. Aber im April 2024 war es so weit: Mein…

Tables are arguably the worst part of Markdown.
No horizontal lines except for the mandatory one at the top.
The only feature is the possibility to align cells. 
 Org Mode does much better, but isn’t perfect either. 
 Don’t get me wrong. It’s nice to have a simple tool for simple tables.
But sometimes I need more customizability. 

Every blog post should include a timestamp.
In fact, this extends to almost anything online and even offline. 
 Also, don’t make me look for the date.
Put the date as obvious as possible, preferably at the beginning of the post. 
 I was reading Julia Evans post about nix and it was not immediately clear to me if this was a recent post.
Only when I copied the URL to…
