Introduction to UEFI HTTP(s) Boot with QEMU/OVMF
The historic go-to solution for network booting is PXE. PXE is based on DHCP and TFTP. It is tricky to correctly configure, even trickier to make it highly available and good luck with the security with this clear-text unsigned protocol.

Selfhosting on Localhost
As a software engineer with a bit of job-induced paranoia, I love the idea of escaping the claws of big tech via self-hosting. In recent years, a plethora of amazing free and open source projects have emerged, providing alternatives to everything from Dropbox and iTunes to Android Home. However, I don’t want to manage…

The webdev pushes their changes to some branch of a publicly available git repository, and some web server somewhere serves the current tip of that branch as the website.
