Getting started with encryption of documents

What is the problem

If you work with sensitive (human) data (e.g. anything that contains an identifier of an individual), you occasionally want to share that data. The most straightforward way to do so is to send them by email (and yes - we are all guilty of that!). The problem arises, if the data get into wrong hands. Let's say you send the email accidentally to the wrong person. Or worse, without your knowledge, the email gets into the wrong hands.

The good news is, that there is a secure & handy solution for this. But let's first have a look at some other solutions.

What about dropbox and other file hosting systems? ❌

Revert to WSL 1 from WSL 2

I'll spare everyone the rant. This gist will be an all business how to revert to WSL (Windows Subsystem for Linux) on Windows 10 from version 2 back to version 1.

Note that enabling Hyper-V destabilized the (highly managed) system my company provides me. This is probably unique to the image used for the machine and the updates that base has received. So I'm not surprised by the issues people are having with Hyper-V and the Virtual Machine Platform.

My personal Windows virtual machines remain on WSL 1 because I just don't have the energy to deal with all the drama when I've already put in a full shift at work.

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.
