Backup solutions are great. But can you make the static files more useful? Here’s how you can turn them into a self-hosted archive that can be accessed in similar ways to the real thing.
PGP is an interesting technology. But usability in the traditional use-case has often been criticised. But can it be used to secure emails in case the email account gets hacked, to reduce the risk of a “complete digital life takeover”? Here’s a thought experiment and an analysed candidate solution.
In this tutorial, I’ll walk you through how you can add a new bridge and/or VLAN to an OpenWRT based router using the LuCI web UI.
A (somewhat lengthy) tutorial showing you how to build a ROS2-based robot system for flying a spacecraft in the Kerbal Space Program game. If you’re just curious, or a ROS1 user looking for an end-to-end walkthrough of building something with ROS2, then this is for you. You’ll find text, diagrams, code and a video.
Cling is a pretty cool C++ interpreter built at CERN, which shortens typical C++ development workflows by giving users a REPL (Read-eval-print loop), which means that you can type your C++ code, press ENTER and see the result almost instantly. However, out of the box Cling does not print the contents of structs, classes etc. In this blog post, I explain how a custom value printer can be added at runtime to expose the encapsulated data.
Over time, I’ve encountered various issues with booting my Windows 10 VM that’s accelerated using PCI-passthrough, VirtIO etc. I believe some of the boot issues to be unique to that kind of setup, and have not always easily found solutions to these problems online, so I wanted to document my experiences for the benefit of others.
I’ve been experimenting a bit with Software Defined Radio, and specifically the gqrx and gnuradio tools. The I/Q (In-Phase/Quadrature components) recorder in gqrx can record .raw files, which handily record the entire spectrum visible in the waterfall window. In this blog post, I will show how to load data from those files, extract a subset of the recording, and save that into a new file. Unlike .wav files (for which a plethora of tools exist), I found little documentation on how to work with these files outside gnuradio/MATLAB/Octave.
In this blog post I describe the journey from buying a Rock64 single board computer (basically a less mainstream but more powerful Raspberry Pi), booting, troubleshooting and porting Arch Linux ARM to it.
In this blog post, I will explain how to compile the Open Overlay Router (OOR) software for MIPS and how to set it up on an Ubiquiti EdgeRouter Lite to participate in the Locator/ID Separation Protocol (LISP) beta network.
Sometimes you might want/need to use NAPTR DNS records as part of your SIP setup. A while ago it was quite difficult to find DNS providers that support them and don’t charge you an arm and a leg for it, but the situation has improved quite a bit. Below are some DNS service providers that …
