You can use WinBoat or WinApps or even LinOffice to run Microsoft Office in a VM that feels like a native app. Or you can instead try Collabora Office which looks like Microsoft Office, but is based on LibreOffice
$10 per TB is actually crazy cheap even for used enterprise drives! Unimaginable in this day and age
Good memories
... What you’re refering to as GNU/Linux, is in fact, systemd/GNU/Linux, or as I’ve recently taken to calling it, systemd plus GNU plus Linux. GNU/Linux is not an operating system unto itself, but rather another free component of a fully functioning systemd init system made useful by the systemd daemons, shell utilities and redundant system components comprising a full init system as defined by systemd itself.
Many computer users run a modified version of the systemd init system every day, without realizing it. Through a peculiar turn of events, the version of systemd which is widely used today is often called GNU/Linux, and many of its users are not aware that it is basically the systemd init system, developed by the Red Hat.
There really is a GNU/Linux, and these people are using it, but it is just a part of the init system they use. GNU/Linux is the os: a collection of programs that can be run by the init system. The operating system is an essential part of an init system, but useless by itself; it can only function in the context of a complete init system. GNU/Linux is normally used in combination with the systemd init system: the whole system is basically systwmd with GNU/Linux added, or systemd/GNU/Linux. All the so-called GNU/Linux distributions are really distributions of systemd/GNU/Linux!
What do you mean by "use SHA1 for Git"? Are you referring to commit hashes? They probably don't have any security implications that would warrant a stronger hash
For professional email I recommend firstname.lastname@domain because it's very common and lets people almost uniquely identify you from your email address alone. You could also register a domain such as lastname.com such that you can use firstname@lastname.com. Just make sure to use a reputable email host to make sure that your emails don't end up in spam.
Preferrably all bricked up
You did all this as a teenager? Impressive
