I’ll still argue that HD-DVD is mostly the better technology. The things which BRD tried to claim were what made it better were not things which would fundamentally have stayed with BRD. The interactive layer was finalized first on HD-DVD and was better.

All that said. I have many HD-DVDs and the drive. Before my drive fails, how would I archive my movies. 🤔

Even if it were inspired, it is significantly different the way it’s written. I’ve hit these same challenges before, so I’m more inclined to think it is independent discovery.

Someone on Reddit once thought I was a bot because I use proper grammar. 12 years of comment history would have demonstrated otherwise, but it wasn’t a battle worth fighting.

That’s one way it is weaker, but moreso because it reduces the entropy. If a user can provide a password which uses 26 letters, upper and lowercase, 10 numbers, and an unrestricted set of symbols, but for the sake of argument we’ll say 10, then there are a lot of possible combinations. If you are limited to only 12 possible at max, it is 46^12. Now you impose an artificial requirement that it is one of each, then it actually weakens that further by making the hacker know that there is one of each in there so it is 2626101046^8. Or roughly 910^19 vs. 1.3610^18. I personally try to use passwords which are between 16-20 characters long, or roughly 2*10^33. By restricting the total number of characters and forcing specific combinations, then the password is less cryptographically sound.

Using this calculator, https://bitwarden.com/password-strength/, it is a difference of 3 hours vs. centuries using the bank’s mandate vs. only lowercase and 20 characters.

Edit: Something seemed off about the math. Should have multiplied instead of added, but still less sound secure because there are imposed requirements. The biggest issue is that there is an upper limit of 12 characters.
