Hello! I was going to ask a question about the Construction details section on the Feistel network Wikipedia page, but I think that it doesn't add any value to the StackExchange network, so I'll post it here instead.
The described encryption algorithm states that «for each round i = 0, 1, 2, ..., n, L[i+1] = R[I] and R[i+1] = R[i] (+) F(L[i], K[I])»
Unfortunately, it looks like this algorithm will perform 5 rounds for n = 4.
The described decryption algorithm "just works" because it also undoes the extra round, but there is an extra round.
This excellent answer and every paper I've seen on that matter seems to do rounds from 0 to n - 1 considering zero-indexing as expected.
Don't hesitate to tell me if this "semi-question" is off-topic. I refrained from opening a question because it doesn't seem that relevant to me.
By the way, nice to meet you all! ...and I'll keep scanning @reed's QR code every day with my CVE-2018-3900-compliant Yi Home Camera, just in case. ;-)

@ThoriumBR How do I delete people who watched child pornography?
Seems the most straightforward solution to the problem

@0x2b3bfa0 That seems like a question for Cryptography

I don't really like any of the answers here (although some are better than others), but I've been on vacation all week and don't feel like posting an answer myself. Anyone here want to try again? It's a good question so I would happily provide a good bounty

Q: Owner vs IT employee. Security and passwords

Putz I own a company that has hired an IT employee. He has all passwords to servers, work stations and data. He is refusing to share or supply these passwords (Keys to the Kingdom) on the grounds of security. He has pointed me to your site along with many others, about the implications of sharing pass...

Although let's be honest - I doubt many people here care much about the rep :)
 
Why is everything getting removed?
To me, that sounds like a policy problem
Like, they don't have a policy that says who has access to what and how
 
It sounds like they hired their first IT employee who is creating root accounts and refusing to share passwords with the owner for "security". Obviously you aren't supposed to share passwords, but as the owner of I had an employee who was the only one with access to key accounts and who refused to plan for the bus factor, we'd sit down and an hour later he would either see things my way or be fired
 
"break glass process" is used exact for that
if the admin fears credential sharing will compromise security, create another admin with a very long password, print it, put on a tamper evident envelope and hand it to the owner for safekeeping
but I agree that his behavior is to protect himself, not the company

True
I realize what a fucking boring statement that is
But I am tired

I left a comment on that question, IMO the problem is that they don't have a security policy or a "documented practice" anyway, for what they need. The IT guy is right because he can't give passwords to possibly incompetent people. The boss is also right because there's the "bus factor" to consider. So they need a policy that states who can have the passwords and when they are allowed to use them
Example: "Passwords are locked in the safe and Boss can get them, but Boss is only allowed to use them in case I get fired, or in case of emergency when I'm not available within X hours/days, etc."
As I said in the comment, Elon musk sure owns his rockets, but that doesn't mean he has the right to fly them (as a pilot) just because he's the boss
 
2:35 PM
What do you mean it's a nuanced problem with both parties having valid viewpoints and the solution requires mutual effort?

I WANT TO HEAR THAT I AM RIGHT!

Unrelated question: does anybody know how "leaving" this chat works? I usually click on "leave", but I'm not sure it always works. If I just close the tab or log out, will I appear to be here as a ghost forever?
 
@reed From testing using a second window in private browsing mode, when using "leaving", one fully leaves and is removed from the ghosts.
 
I think you will also time out after a while
I think the chat works using websockets
 
I'll try to join another room, then only leave by closing the window and see if I ever disappear from there
 
Yeah you disappear when you leave, you are set as a ghost when the chat is open somewhere, unless that changed.
And @MechMK1 thank you for your comment, it was thoughtful to come out of your way to thank the contributions done :)
 
@ElieSaad You're most welcome. I'm always happy when people come to SE to share some firsthand knowledge.

confirmed, it times out after a while, and you leave the chatroom

@reed Nice, just like I expected
So how is everyone doing?
Are any of the mods still here? I think someone is spamming in the answers
All three of his answers recommend one specific vendor
 
9:37 PM
I actually didn't expect to leave the chat just by, well, leaving it. Because I always see a lot of users in this room, like "ghosts" (faded avatars), yet I don't recall seeing them chat or even join this chat
unless they have been leaving a tab open for months
 
Could be some mobile browser just constantly keeping the tab open in the background?
 
Could be. We could ask @ConorMancone maybe. I think he's the kind of user that never leaves this chat, I think I always see his avatar here, even if just faded
However they must have something they leave open, because IIRC during the weekend the "list of ghosts" is much shorter
 
Yeah, on the weekends I'm not here either because I usually visit the DMZ when I am avoiding work or when I feel depressed and need someone to talk to

and on a different tone, there's no more F*cking in Austria...
 
fugging right.
 
> They finally grew weary of Fucking, its current name, which some experts say dates back to the 11th century. Minutes from a municipal council meeting published on Thursday showed that the village of about 100 people, 350kmeast of Vienna, will be named Fugging from 1 January 2021.
English speakers will adapt... "what the f*gging name is that?"
wtf will be a retronym: what the fugg
in 10 years or less, the Mayor of Fugging will have to rename the city again...
 
I didn't know that. That's a stupid marketing move. I mean, with a name like that, I'm sure some people would have been willing to pay lots of money to be able to live there
Just to brag about it
 
11:58 PM
I actually think they got fed up
people kept stealing the signs
