Environment Setup Notes:

1. Install VirtualBox
2. Install Linux Mint (based on Ubuntu -- I prefer MATE desktop, but many people like Cinnamon)
• Desktop Comparisons: MATE versus Cinnamon
• Install Guest Additions - device drivers and system applications that optimize the guest operating system for better performance and usability.
3. Enable "Shared Clipboard and Drag'nDrop": Settings -> Advanced
4. Configure shared folders, then run the following commands..
1. run: sudo usermod -a -G vboxsf `whoami`
2. run: sudo chown -R `whoami`:users name-of-mount-point
3. log out, and log back in
5. Update Mint (run): "sudo apt update && sudo apt upgrade -y"

Interesting Technologies related to Linux:

1. Kernel-based Virtual Machine (KVM) - turn Linux into a Hypervisor
2. Docker (Container Technology)
3. TCPDump & LIBPCAP
4. Extended Berkeley Packet Filter (eBPF)
