Switching to IPv6 Near as the World Runs Out of IP Addresses


Internet Protocol version 6

Who could have guessed that 4.3 billion Internet connections wouldn’t be enough?  Certainly not Vint Cerf.

In 1976, Mr. Cerf and his colleagues in the R.& D. office of the Defense Department had to make a judgment call: how much network address space should they allocate to an experiment connecting computers in an advanced data network?

Study Reveals U.S. Power Grid Too Unreliable to be Brought Down by a Terrorist Attack

U.S. electric grid

A new study shows why it would be hard for terrorists to bring down the US electric grid.  

Last March, the U.S. Congress heard testimony about a scientific study in the journal Safety Science. A military analyst worried that the paper presented a model of how an attack on a small, unimportant part of the U.S. power grid might, like dominoes, bring the whole grid down. Members of Congress were, of course, concerned. Then, a similar paper came out in the journal Nature the next month that presented a model of how a cascade of failing interconnected networks led to a blackout that covered Italy in 2003.

Stay Safe in Public
Starbucks is offering free Wi-Fi to all customers, at every location, starting today. Whether you’re clicking connect on Starbucks’ Wi-Fi or some other unsecured, public Wi-Fi network, here’s how to stay safe and secure while surfing a public hotspot.Just because most wireless routers have a firewall to protect you from the internet doesn’t mean you’re protected from others connected to the same network. Lots of wireless hotspots these days are completely unencrypted, usually so they’re easier to connect to (baristas don’t need to be giving out the internet password to everyone that walks in). However, this leaves you unprotected against malicious users in the same coffee shop, so there are a few settings you should always make sure to tweak when you’re connected to a public network…

More than 50% of Facebook members are over 35

Facebook now has more than 400 million active users, up from only 50 million as recently as 2007. If social networking still resembled a young, hip downtown nightclub scene — one day a site is hot, the next it’s not — we might expect the crowds to decamp soon. Facebook would become another Friendster, still around but ghostly, forgotten by most.
