Migrating to AlmaLinux, podman and caddy

Finally rootless and confined containers

 Posted on 2023-10-30  |  6 minutes  |  1268 words

After my last blogpost about MAC, I felt bad for preaching water and drinking wine: I set up this blog in 2021 on an Ubuntu 20.04 LTS (🤮) with an nginx from the official Ubuntu repositories, and then didn’t do much to it except for the obligatory updates. What was already a bit backworldish in 2021 is a bit embarrassing in 2023. Since I’m planning to host more on the internet than this blog, I really wanted to look into containers. [Read More]

Mandatory Access Control (MAC) on Linux desktops

 Posted on 2023-07-22  (Last modified on 2023-09-12)  |  11 minutes  |  2298 words

Motivation I’ve been using GNU/Linux distributions as my daily driver OS on desktop PCs and notebooks for more than 10 years. Linux is a great choice to me, because like most FOSS it values my privacy, it’s fun to use because of its customization options and because it is secure. Because it’s secure, right? If you thought you are better off with e.g Linux Mint than those Mac OS and Windows peasents beause of it’s superiority in terms of security… well, just read this article by madaidan or watch this (German) talk by lubro.

Cat watching powered by FOSS

 Posted on 2023-03-11  (Last modified on 2023-04-06)  |  9 minutes  |  1751 words

Warning Edit 2023-04-06: I recently found out, that a major part of OpenIPC called ‘majestic’ is not open source software, but is in fact closed source. There is a replacement called mini and I am going to test it and update this tutorial soon, but please don’t use this tutorial, if you are expceting open source software like I did. During my next vacation, I want to watch my cats remotely without streaming my home to an untrusted cloud. [Read More]

Project X230 Frankenpad

Modding a Lenovo ThinkPad X230

 Posted on 2023-01-29  |  2 minutes  |  245 words

In November 2021 I decided to upgrade from my Lenovo X230 after over 9 years of service to a Lenovo ThinkPad P14s G2 AMD. After years of heavy usage the X230 was pretty much worn down, resulting in an keyboard with missing keys, small damages to the display and broken plastic parts. Time to rebuild it as a Frankenpad! Since the X230 is not my primary notebook anymore, I am able to do all the mods I hesitated to do, when I depended on it. [Read More]

This article will not explain why you would want to avoid Google on your mobile phone, it will only talk about an approach on how to do it. And if you unironically think an iPhone is a suitable solution, please leave this blog. Overview When it comes to smartphones you have the choice between Apple and Google which means you are caught between a rock and a hard place. Luckily Android is based on the Linux kernel, which forces Google to comply to GNU GPL v2 for the Linux kernel modifications. [Read More]

I hacked myself: Android edition

 Posted on 2021-01-26  |  3 minutes  |  472 words

Besides a crappy Windows Mobile 6.1 phone I owned years ago, I bought my first smartphone in 2012 – a Lenovo A660 from a rather unknown Chinese Smartphone seller. (They did not only declare the package as a gift, they even wrote a gift card which stated ‘Merry Xmas, Yours Dan’) The device was already rooted and came with a custom ROM, which was a nice service, because all official images were Chinese.
