I wonder if this technolgy will provide an alternative to communicating with satelites in space. I think using this underwater laser system is great because it provide security from signals being intercepted.
I don't believe this is relevant to ground-to-space communications. The way I read the article the laser pulse has a short range, ionising the water in the vicinity of the buoy, which creates sound waves which emanate out to wherever the sub is. The laser isn't bouncing back and forth from sub to buoy.
As the communication is via sound and not laser it also means that anyone else in the vicinity could intercept the message. Strong encryption and authentication would still be required.
I agree. The "Hell" in "Hell yeah." emits the passion the person has for what they are say yes to. Whether pitching an idea or asking for a girl's phone number we all want to hear some level of passion in the yes. A simple "Yes." is very close to a "Maybe" but "Hell yeah" says "I agree and I'm am just as paaionate as you are about it."
Free is the key to a successful online company. Google, Facebook, Myspace and Youtube are the top web giants that prove this. When giving something away for free that consumers demand equals traffic. High traffic increases the value of ad space on a site. Google understands this very well and this why they have never attempted to sell any software or features they develope. I'm sure google spend a lot of time and money creating and perfect their free software that programers sell for hundreds of dollars. The internet is the only place were one can profit from giving away their product free. This is why old business models and rules do not apply to Online companies.
Oil rigs should hire their own hackers to test their network security to ensure it is safe. With the rate tecnology improves today once a new program or engineering concept is applied it's very close to becoming obsolete. This is companies must constanly try to penitrate their security and improvise hoow to prevent a hacker from doing the same.
