P2P VPNs allow you to connect two or more hosts together and do some stuff like play games or test out services just like you were on one real physical local network (LAN).

Scripts and functions for handling parsing of bookmark files into more friendly formats.
From some work I was doing in parsing bookmarks back in ~2016, for deduplication and finding similar bookmarks in a collection of 30K+ bookmarks I have accumulated over 15+ years.
The goal was to make this approx constant memory so parsing can happen quickly in very resource constrained environments. Hence the custom streaming XML and JSON parsing.
Now that tools like browser-history exist I'll likely revisit this project in the next couple years since I'll be able to make a lot of progress in just a few hours. At that time I'll likely convert all this into a more public repository.

PXE Boot Setup with GRUB2 Tutorial
There are many tutorials on the internet that tell you how to setup a PXE Boot server with PXELINUX. There are however other options to replace PXELINUX like GRUB2 and iPXE. In this tutorial, I'm going to teach you how to setup a PXE Boot Environment with GRUB2, and later add menu entries to boot many popular OSes.
Notice: I'm not going to repeat the part where you setup the DHCP and TFTP server. Such section in other tutorials still applies to this scenario.
Making the GRUB2 image to be loaded by NIC
think the GRUB2 image as the same as PXELINUX's pxelinux.0 file. Your DHCP server must point to it, and it must be available on your TFTP server. Instead of shoving a blob down your throat and telling you that it just works, I'm going to walk you through the process of making one yourself by using an readily available linux installation.
