Regarding HoudiniFX it seems they have Linux installs, and a free (with watermark) version for hobbyists - https://www.sidefx.com/products/houdini-apprentice/
Other than that I’d say Blender is the goto app, showing up as one of the most popular apps in the Discover app.

My recommendation would be to use clonezilla or a similar tool to make an image of your windows install and save that on the external ssd.
Then I would install Fedora KDE or whatever’s your poison on the internal drive.
If you wanna switch back to windows then you can always use clonezilla, or your tool of choice, to restore the image.
You could also use KVM/Qemu in your linux distro to restore the image into a windows vm.
virt-manager gives you a desktop gui while cockpit + cockpit-machines gives you a nice webui for handling virtual machines in linux.

Both Cockpit and Virt-Manager are available in Fedora KDE’s Discover app if you prefer GUI installs:

I’m a big fan of using https:// in Mull on my Android, and in Firefox on my PC.
Never been a fan of installing more apps then necessary.

Linux Routing Fundamentals

Linux has been a first class networking citizen for quite a long time now. Every system running a Linux kernel out of the box has at least three routing tables and is supporting multiple mechanisms for advanced routing features from policy based routing (PBR), to VRFs(-lite), and network namespaces (NetNS). Each of these provide different levels or separation and features, with PBR being the oldest one and VRFs the most recent addition (starting with kernel 4.3).

This article is the first part of the Linux Routing series and will provide an overview of the basics and plumbings of Linux routing tables, what happens when an IP packet is sent from or through a Linux box, and how to figure out why. It’s the baseline for future articles on PBR, VRFs, and NetNSes, their differences as well and applications.
