- Give honest and sincere appreciation.
- Arouse in the other person an eager want.
- Never show others that you are not interested in what they have to say.

- Green Cloud Computing - GreenCloud can be used to develop novel solutions in monitoring, resource allocation, workload scheduling as well as optimization of communication protocols and network infrastructures. It is released under the General Public License Agreement and is an extension of the well-known NS2 network simulator.
- ns-3 - it is a discrete-event network simulator for Internet systems, targeted primarily for research and educational use. It is released under the GNU GPLv2 license, and is publicly available for research, development, and use.
- OMNEST - OMNEST simulation software has been chosen by R&D staff, researchers and engineers worldwide to investigate scenarios and design alternatives in various wired/wireless networks, interconnection networks, queueing-based performance models and other systems. OMNEST simulations can also be embedded into your own software prod

Software RAID 1 setup on Ubuntu Server 20.04 (or newer)
Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong. And as of March 2021 it's possible that there's a bug as well with how the bios_grub partitions are created when using multiple disks.
Now on to the solution:
- Select "Custom storage layout" when you reach the storage configuration step of the installer.
- If the disks have existing partitions, click on each disk under AVAILABLE DEVICES and then select REFORMAT. This will (temporarily) wipe out the partitions.
