A slight nitpick with the article - `p/q2-q4` (more commonly written as "1. d4" in modern times) is not the Closed Game, it's just the first move of it. There are many, many other lines after 1. d4 besides just 1. ..d5, most of them quite open!

It is the beginning of the closed game, which is what the article says. Seems like a vacuous nitpick.

Closed game is 1. d4 d5. There are quite a few opening lines that start with 1. d4, but do not continue into the closed game.

I use a diceware[0] passphrase for my Keepass database. I was inspired heavily by XKCD comic 936[1]. My only issue with password managers is that they are a single point of failure and are juicy targets for hackers, so I usually vet them and audit them thoroughly before I use them. I am one of those rare people that actually looks at the source code of password managers to look for flaws in the implementation (I some…

Your switches/keycaps must be kind of crappy if there's that much wear on them from typing the same thing often

I had a password for an old school system (which I wrote) that was "any 21 characters where the 21st character is a 'z'". People would watch me type it (mashing 20 keys then the 'z') and be amazed I could remember a password that long.

In the early days of unix, people didn't take passwords that seriously and often shared them.

I would have borrowed "/.,/.," a long time ago had I heard about it sooner. That is just way too convenient.

My brother used to use asdfghjkl;' as a password so he could just drag his finger across the keyboard from the a key to the enter key. The original swipe to unlock!

I'm shocked at how well the old hashing stood up; sure, it's totally crackable today, but a well-picked password still took 4+ days to crack on modern hardware, which is remarkable. (Granted, it doesn't sound like they did anything fancy like throwing a hundred cloud instances at it or something; I'm not saying you should use DES today:) )

Would this suggest that 3DES with a sufficiently long password is still safe for now?

Is it? I mean, I'm not a chess expert, but can we actually call a chess game open or closed from only the first move?

1.d4 d5 is called the Closed Game. It's the name of the opening, just like the Ruy Lopez or the Benko Gambit.
