Assuming that a password character can only be a-z, A-Z, 0-9, and 10 other characters, and assuming that a password has exactly 6 characters, you would have to try on average (72^6)/2=69657034752 passwords. Assuming you can do 100 tries per second, that would still take more than 8062 days, or more than 22 years on average.

Using a dictionary attack will cut that time WAY down, if the targets used words as passwords.

You'd only be able to verify if the Universe we live in were a simulation, if you could witness/observe something _outside_ of that Universe / simulation.

Not necessarily. If I wanted to find out if I were living in a computer simulation, I would start looking for an exploit. Hack the universe!

Comment A concept for higher education (Score 2) 335

Some years ago, when fantasizing about being a billionaire, I gave thought to how I would improve upon education.

The solution I came up with was to found my own network of private schools and colleges, which I could hold to a high standard due to them being under my control.

The private schools and colleges wouldn't be free to attend, per se, but I'd make it sort-of-trivially-easy for an ambitious student to gain admittance to the private high school without paying tuition (say, the student must participate in on-campus work, organized charity volunteer work, or extracurricular research work, or simply be gifted, etc).

Exceptional students at the private schools would be given scholarships to the colleges, and billionaire-money would attract top-tier professors and researchers. I fantasized about eventually running the top private research institution in the world.

In essence, you create a brand. Use the money to create top-tier colleges under a brand name, then 'franchise' private high schools under the brand, and funnel kids from those schools to the colleges.

Punctuate the concept with aggressive job placement assistance, complimentary career counseling and even therapy for all graduates that extends for for a lifetime beyond graduation. (I think this point is a huge idea in itself, to be honest, and is something that universities should do anyway).

Being a graduate doesn't just mean you got a degree there - it means you're part of a lifetime club, a member of a 'living network' (as opposed to 'social network') with high ideals in mind. Graduates would be encouraged to serve as mentors to students in their spare time in exchange for their lifelong benefits.

Above all, this all could exist without being exclusionary toward non-'members'. For instance, tuition credits could be earned for students who agree to tutor public school students in the community and 'take them under their wing'.

Basically, in the end, you have what a real society should be - a nurturing network of educators, counselors, mentors, and just plain *people* helping each other out for their entire lives. A community, you know? Rising tide, lifting boats.

I actually think this sort of thing could be profitable, and not an expense, in the long run. Once you are established as a top-tier educator, your 'product' will become desirable and those with money will gladly pay for their child's enrollment. Build a solid reputation for producing high-quality, well-rounded, well-adjusted, successful graduates, and marry that to the benefits of being part of this fantastic 'life support group', and you've got one hell of a desirable thing, here.

In short, if you want to do something right, do it yourself. Throwing money at a flawed system isn't going to fix anything. It's like trying to fix a leaky bucket by pouring more water in it.

Slashdot-reading billionaires, feel free to run away with my ideas and do something great with them. Also feel free to contact me if you need help in the implementation. :)

Comment I admire their spunk, but... (Score 4, Insightful) 275

My friends and I have already switched to Dogecoin. Sorry. And when you start mining that, we'll move again, etc.

I'm not serious, I haven't invested in any virtual currency. But isn't this a sort of problem? When it looks like a Major Player moves in and starts dominating the generation of your pet virtual currency, why wouldn't you just jump ship to the next one, where you can stand a chance to make money in the early days of generation?

It's not like mining gold. Gold is gold and there's only so much of it, and it's there or it's not. These virtual currencies only have value due to consensus, and can be abandoned on a whim, especially when some guy comes in with his 1.4 million mining chips and upsets everything. I know there's a limited number of bitcoins available before computation is done, so in that sense it's 'limited' like gold and thus perceived to be a scarce valuable item, but unlike gold, the users can just up and quit Bitcoin forever, especially when they sense 'unfairness' in the operation.

Comment Re:EL and SCUBA (Score 1) 127

Don't worry, it involved sound too. In fact, I came up with the idea the other day during a discussion with someone about the current missing plane crises - he asked why airplane black boxes (that end up in the ocean) can't transmit an underwater ping that could be heard for miles by listening stations. That would never be practical, of course, but it got me thinking about underwater signaling in general. I live in South Florida and am surrounded by boat and diver culture.

Comment Wow, timing. (Score 4, Interesting) 127

I was working on a personal design project with very similar features, for undersea divers - an electroluminescent (EL) panel or wire system for divers to use to signal each other underwater, even at distances where hand signaling would be an issue. Different colors for different situations, and the ability to 'flash' a sort of morse code communique to one another.

A diver's illumination would also light up or flash when air reserves reach low levels or the diver is otherwise in distress, so others could recognize the issue and come to aid.

Feel free to steal the idea and run away with it, if anyone reading this is in the industry. Like I said, it was just a personal design project that I was planning on giving away to improve the general state of things.

System going down in 5 minutes.
