This cheatsheet assumes the user is knowledgeable about bare installations of virtual private servers on cloud providers and is looking for quick but comprehensive instructions.
Some trivial commands might be missed or skipped.
However, this document can also work as quick tutorial for newcomers to the RHEL eco-system.

Most new PCs don't come with DVD drives anymore. So it can be a pain to install Windows on a new computer.
Luckily, Microsoft makes a tool that you can use to install Windows from a USB storage drive (or "thumbdrive" as they are often called).
But what if you don't have a second PC for setting up that USB storage drive in the first place?
In this tutorial we'll show you how you can set this up from a Mac.
You can download the ISO file straight from Windows. That's right - everything we're going to do here is 100% legal and sanctioned by Microsoft.

You can scale a SQLite database to multiple GByte in size and many concurrent readers by applying the below optimizations.
(some are applied permanently, but others are reset on new connection)
pragma journal_mode = WAL;
Instead of writing directly to the db file, write to a write-ahead-log instead and regularily commit the changes. Allows multiple concurrent readers, and can significantly improve performance.
