It's been decades. That means "Check!" right?

Exclam! Generally a good move, perhaps even unexpectedly so. Double exclam, !!, being a brilliant move, especially one with flair like a sacrifice. Triple exclam is reserved for the games of Emory Tate. ;)

Emory Tate must have been extraordinary..?

the most amusing thing is the exclamation mark on such a banal opening move.

At least in modern usage, giving the exclam to signal "I prefer this opening move" isn't uncommon, so it's not a stretch to think that it was done in the seventies too. Also it rounds the whole thing out nicely to eight characters.

I still have 0 idea what's interesting about this. How is this a chess move?

the password is the last part: p/q2-q4!

it's a notational way in the chess program (written by Ken Thompson) to describe a chess move, "pawn from Queen's 2 to Queen's 4."

A very common opening move that "puts a pawn in the center, controlling the important e5-square, and opens the line for the Bc1."[1]

The notation is old. Modern notation would just write it as "d4" because there's only one piece (a pawn) who can move to that square as the first move and only one spot from which it can move (d2).

Eh, he was typing that phrase at a work keyboard everyday.

Would you be OK with your use of work bathrooms being made public? You can have an expectation of privacy while using other people's stuff.

If I was writing down offensive stuff about a coworker in the bathroom, that seems fair.

I don't know what to think about this. A password is supposed to be secret so I don't know what a naughty phrase in secret is a violation of? It is not very different from writing something naughty in a private diary, or even thinking a naughty thing.

The guy wasn't fired for the password, he was fired for the sexual harassment of a coworker. And nothing you do on a work computer is secret from your employer. It's not a "private diary" if you're using your employer's hardware.

If he was fired for sexual harassment, that is one thing. But a naughty password on its own? That was maybe not the case here but that is what I have doubts about.

Back when I worked in IT many years ago, one of the things I did each week was run JohnTheRipper on our password file. If it cracked your password, it sent you an email saying your password was weak and you had to change it. If you were in the next week's batch, it emailed you and told you "your password is foobar, which we discovered by cracking the password file, and it is weak. You must change it". Yes, I emailed…

I'm all for the effective strength enforcement and ejecting the creepy guy, but some people do have strong passwords that, a bad idea though it may be, embed something deeply personal to them. Just something to keep in mind before automating the sharing of cracked passwords for otherwise legitimate purposes. I consider my passwords my private information, even if they are no longer secure from a technical standpoint…

This is a bad analogy.

Actually, it's a rather perfect analogy.

People have some expectations of privacy and it's not normally considered acceptable to violate this.

Sometimes this stuff is untried in court or falls into a definite legal grey area and usually the policy is to err on the side of caution and simply assume that if something is commonly expected to be private, then it's private and should be kept so.

If we were investigating a user for XYZ and came across a file named "Personal Diary 2019.txt" or whatever, I can assure you that HR would not want us to open that file. Possibly if HR found out they'd declare the investigation tainted and want to stop it right there.

This isn't hard. Don't want your personal info on a work computer? Then don't put it there. Work computers, networks and other resources are not yours. They belong to your employer.
