Mastodon is a decentralized microblogging network, that is similar to Twitter, and can be self-hosted on your own server.

Unlike Twitter, Mastodon consists of many different servers that are connected worldwide. This connection is established through the so-called Fediverse.

It doesn't matter if you create your account on your own self-hosted Mastodon instance or if you create an account with one of the numerous providers. Since all servers are connected, you can interact with your account from anywhere.

Since the sale of Twitter to Elon Musk there is a huge growth of accounts within Mastodon. If you want to get your own Mastodon server, I'll show you how to start your own Mastodon server with Docker and Traefik.

When you completely discharge a MacBook with an M1 processor and the device runs out of power, it will lose the date and time on the next boot.

Normally there is a backup battery on a mainboard, which keeps the time and date in such a case. I cannot yet say what Apple has done here exactly and why the problem occurs. But I have a solution for you.

I recently faced the same problem and tried to set the Mac to automatic date and time setting via System Preferences > Date & Time.

OwnCloud decided to develop a completely new product a few months ago. In the meantime, there are already the first beta versions of the new OwnCloud with the name oCIS. oCIS stands for ownCloud Infinite Scale and should make clear that this cloud solution should be very scalable.

Newly, it is sufficient to start a single container with oCIS, which already contains all the necessary dependencies. So no database and no further containers are necessary to self-host oCIS.

In the following I would like to show you a setup how I run oCIS with Traefik as reverse proxy on my own server since the release of the first tech previews.

AdGuard Home is a Selfhosted DNS server that can block Ads and Malware Domains inside your network. AdGuard Home is an alternative to a PiHole, with one big advantage: AdGuard can natively do DNS-over-TLS and DNS-over-HTTPS, and expirmentell it even provides support for DNS-over-QUIC. With a PiHole this would theoretically be possible as well, but you need additional software and some manual configuration.

For this reason, today I want to show you how to set up AdGuard with Docker. We will use Traefik as a reverse proxy and focus on DNS-over-HTTPS.

Standard Notes is a note-taking app that you can use on all major platforms and mobile devices. With Standard Notes, your notes are end-to-end encrypted and therefore protected from prying eyes.

I've been a fan of Standard Notes for a long time. Unfortunately, the annual subscription has always been too expensive for me and I have only used the free version of Standard Notes. Besides the hosted version of Standard Notes, there is also the possibility to install your own self-hosted Standard Notes instance on your server. With all premium features and even for free.

Unfortunately, I haven't found any instructions on how to set up Standard Notes together with Docker and Traefik as a reverse proxy. Therefore I decided to explain my setup to you.

Joplin Server is a self-hosted solution to synchronize your own notes, it supports multiple clients for Desktop and Mobile and comes with an optional end-to-end encryption.
