Sysadmin Myths

So random Saturday thought after having beers with some friends last night. We somehow ended up on this topic about IT myths (not sure if Myth is the right word here, but come on the journey with me).

All those things some people swear by, but aren't necessarily true or has more to the story than meets the eye usually. Some are funny because surprising, while others are just pure nonsense, but people keep saying them anyway.

Here’s what I’m wondering: What 'myths' have you guys heard that turned out to be totally true? And what are some that are complete BS, even tho people still swear by them?

Examples that pop into my mind, while waiting for the bus:

True Myth - "Just turn it off and on again", super basic, but the reboot trick actually does work a lot of the time. Like, it legit clears up so many weird issues, especially when processes are hung up or memory needs a reset. The average person wouldn'y get it, but the sysadmin is running a process overview in his/her head.

False Myth - "Clearing cache = speed boost" – This one’s everywhere, but it's kinda a half-truth I guess (based on last night's discussions). Sure, clearing cache can help if it’s super clogged up or corrupt or whatever, but doing it too often actually slows stuff down sometimes cause your system has to re-download things over and over again. Double edged sword.

What other 'myths' or low-key funny things do you guys run into? I feel like there’s a ton of these floating around.
