Quo Vadis SWDT?

Follow-up to SIG-Windows weekly meeting from Jan 2, 2024, this is my brainstorm of ideas and issues about the state and future of SWDT. It turned out to be not as structured and systematic as I wished, apologies

Learning CNI and Kubernetes Networking

Apparently, after a while of using Kubernetes, everyone comes to the point realisation there is a need to dive into CNI and the overall networking deeper. So, here is my diving kit:

• YT: Introduction to CNI, the Container Network Interface Project by Bryan Boreham & Dan Williams
• YT: Container Network Interface (CNI) Explained in 7 Minutes - why CNI was even created
• YT: Webinar: Kubernetes and Networks: Why is This So Dang Hard?
• YT: Kubernetes Networking 101 hands-on workshop by Randy Abernethy, RX-M LLC
• YT: Kubernetes Networking Intro and Deep-Dive by Bowei Du & Tim Hockin, Google
• YT: Kubernetes Networking Series playlist with in-depth explanation

Learning libvirt

Random list of resources I've found informative during my learning of libvirt and related technologies from a software developer perspective and Go learner too as prep for an exciting git using libvirt and Go.

• Book: Foundations of Libvirt Development: How to Set Up and Maintain a Virtual Machine Environment with Python by W. David Ashley
• Book: Mastering KVM Virtualization
• Book: KVM Virtualization Cookbook by Konstantin Ivanov
• YT: Libvirt: Hypervisor independent virtual machine management
• YT: Introduction to libvirt APIs for KVM - Daniel Berrange, Red Hat, KVM Forum 2011

Running BuildConsole.exe of IncrediBuild 9.4 to build a large project using Visual Studio 2017:

• Machine 1: Intel Xeon E-2670v3 with 24 physical cores
• Machine 2: Intel Xeon Gold 6230 with 40 physical cores
• RAM 64 GB on both
• HDD: SSD on both

The source code tree git clean-ed, IncrediBuild history and cache cleaned and machine restarted before every build.
