Use PGP/GPG to protect email accounts?

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.

Custom type value printers for Cling

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.

Fixing PCI passthrough Windows 10 VM boot issues

Windows 10 booting, showing only the Windows 10 logo and no spinners or any other loading indication

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.

Basic gqrx I/Q and gnuradio file editing

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.

LISP on Ubiquiti EdgeRouter Lite

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.
