TL;DR: This article describes how to configure custom static networking with Podman Quadlet and Netavark as the network backend.

Yesterday, I finally carved out some time for Kingdom Come: Deliverance 2.

Unfortunately… my Steam Deck OLED was dead. I plugged it into a 200W USB-C charger, expecting that friendly white LED blink, but instead—nothing. LED off. Silent. Lifeless.

Here’s the journey I went through to bring it back to life.

A few weeks ago, my friend Ondra and I performed a significant refresh of our weekend house network.

The objectives were:

1. Connect two buildings with a fiber link
2. Install an LTE dish to provide better Internet connectivity

The further objectives are:

3. Replace the old SSIDs with a single SSID to enable seamless roaming across the property
4. Segment the one newly created network into multiple VLANs and reassign the existing networking and IoT devices
5. Set up new firewall rules to secure the infrastructure and allow only the necessary traffic

Do you have your own public domain name? Do you manage your own DNS server(s)? And do you have DNSSEC enabled? If you answered yes to all of those questions, then you probably want to monitor your DNSSEC setup. This post will show you how I do it.

I will show you how to create a daily backup of your Mikrotik configuration. This uses ssh, bash, and systemd-timer. The aim for this mini project is to be as simple as possible but it supports multiple target devices!

TL;DR: This article is so far about how to disable iptables integration and choose different addressing for the ‘bridge’ (default) network.

This post will be about continuous integration between [Open Build Service] and [GitHub].

TL;DR: We should write proper commit messages - not only GitHub pull request descriptions.

This will describe how to make your openSUSE machine send e-mail via reliable relayhost of your choice using Postfix. I will use gmail as an example.

This is a step by step guide for installing openSUSE MicroOS within QEMU. This can be easy to customize or automate. It may help you on other platforms too.
