Published on in 👨‍💻 Dev

I got the question how to solve the problem that when backing up the storage of a dockerized Postgres database (using Resticker) it could be that the backup is corrupt because the database is still running.

Ubuntu 20.04 - Focal Fossa

Published on in 🔗 Links

Ubuntu 20.04 (Focal Fossa) got released today. I’m already using it for a week on my desktop and have to say it’s an awesome version. Gnome 3.36 is really smooth and the new features (like dark mode) are really pleasant. Ubuntu is in my eyes the Linux distribution that “just works”.

Use Telegram as a notification service with Go

Published on in 👨‍💻 Dev

Telegram is my favorite messenger for chatting. There are many reasons for this. But Telegram is also very suitable to use it as a notification service for your own projects. For example I get a daily overview of the number of page views of my blogs, but also notifications about new Webmentions, or likes and announcements via ActivityPub are sent to me via Telegram.

Fortunately I have a pretty high traffic limit, which I would never reach with my VPS at Hetzner Cloud, but BunnyCDN now offers a new feature called “Origin Shield”, which can help to significantly reduce traffic to your own server by adding a second cache layer between edge server and the origin. Nice! 👍

It gets worse and worse… My spam folder collects more and more emails from some Chinese spammers who want to sell me masks against corona. No thanks, I’m not interested.

The problems with hard wrapping email body text

Published on in 🔗 Links

Martin Tournoij has written an article about line breaks in emails. Some people think that in text emails, lines should not be longer than ~78 characters. I also find that emails that have been adjusted to this limit look terrible on the smartphone because the maximum width is narrower than 78 characters.

World map of domains

Published on in 🔗 Links

British domain registry Nominet created a world map of country-code top-level domains. It’s really interesting to see that .tk (Tokelau) is is the world’s largest ccTLD, because registration is free and no expired domains get deleted. After that comes .cn (China) and .de (Germany).

After reading this tutorial about how to mirror a Gitea repository to other Git hosting services like GitHub, I decided to follow a new strategy regarding my projects. I will use my main Gitea instance for all my public repositories and then mirror them on Codeberg and GitHub. I will also migrate projects from GitHub and Codeberg to my Gitea instance and replace the repos with mirrors.

This method gives me full control over my projects and I can create new mirrors or remove old mirrors at any time and I am not dependent on any service.

Why I use tools like Docker and Flatpak

Published on in ✍️ Posts

I admit it, I am a big fan of pre-packaged software. Software that I simply set up by typing a single command or just adding a few lines to my existing configuration. I like simplicity and this kind of software makes things a lot easier and lets one focus on getting work done.
