That is my question too... What did they detect? Who was watching the network so closely as to notice this? Why? Is there an ongoing privacy violation going on by schools to keep their networks clean? It just kinda leads to more questions... Who's watching the watchers?
Don't be so dense. Some people probably complained when they went to vote but the computer said they already voted. A few more of those complaints and it would not be difficult to figure out what's going on. At this point they only needed to see which IP address is casting all the votes generating the complaints.
Is that it limits information sharing.
The biggest problem that the internet caused is that it destroyed culture. Worldwide.
Everyone has this common generic culture now.
This kind of culture didn't exist before the internet. Before the internet, you actually had societies develop and advance the arts. But, if you didn't notice already, culture has pretty much frozen since around 1995.
People wear the same clothes as they do in 1995. Style hasn't advanced like it did from the 50's to the 70's. Or from the 70's to the 90's.
People listen to the same kinds of music.
They use the same grammar and language from 20 years ago.
And so on.
It's a pretty well documented phenomenon, and a great Vanity Fair article from a couple years ago describes this perfectly: http://www.vanityfair.com/style/2012/01/prisoners-of-style-201201
The whole idea of information being free and shared by everyone is actually destructive to society, since that means information becomes devalued when culture becomes democratic. It devalues professional tastemakers, causing populist sensibilities to take hold, which is the exact cause of cultural stagnation. Democratic sensibilities are always obvious, and can never advance the state-of-the-art that professional tastemakers can.
So, not everyone needs to see the same movies, listen to the same music, and so on. It is perfectly fine to limit these items, to make sure there ARE "have-nots". People don't HAVE to have every single goddam song in their library.
We really do need to limit the spread of information, through costs, DRM, or other means, to cause society to advance. Right now the world is frozen in 1995, because information is too open.
Seriously, it is perfectly fine to not know things or to have things. Your life is going to be just fine. But the democratic population wants everything.
Limit them.
Why is this modded -1? I'ts actually a pretty interesting argument, and one I had not heard before. Moderators, using your points as means for censorship makes YOU the bad guy.
The point of the salt is that previously generated and downloadable rainbow tables are of no use. Making new ones would kindof defeat the purpose, as you're effectively brute forcing a tough, hashed password anyway at that point.
This is why it's good practice. It helps mitigate complexity concerns over user supplied passwords, and can make cracking multiple account pwd hashes unrealistic.
I should have just modded this up instead of posting my one word comment. My bad.
Congratulations. You've flunked encryption 101. You never send the plaintext password over the wire, because you can't trust the middleman. Salt and encrypt on the client end, then salt and encrypt on the server end.
SSL is better than anything you could cook up on the client-side, ya dummy.
Work without a vision is slavery, Vision without work is a pipe dream, But vision with work is the hope of the world.
