Superhydrophobicity – say what?

superhydrophobicity

With GE’s new Super-Repellent Plastic, self-washing buildings, cheap diagnostic chips, and free-flowing honey jars are possible.

superhydrophilicity

Since 1995

Used in products that defog glass and enable oil spots to be swept away with water. Such materials are already commercialized as door mirrors for cars, coatings for buildings.
The surface can be reversibly switched from being superhydrophilic to being superhydrophobic with a very small change in temperature.

The Botnets Are Busy

The bots are marching on, and on, and on, as my firewall log screen is almost rolling. Yesterday and the day before, I had more warnings in one hour than I usually get in one day. The botnet was working overtime.

A botnet is a collection of computers that are running programs ( usually worms, Trojan horses) on computers that have been compromised/infected and are now under the control of someone else other than their owner. They discreetly take hold of a user’s computer on and remain hidden while they launch their malicious attacks. Typically, a botnet can range in size between 10,000 and 100,000 infected machines.

I traced back (ping) the source IP addresses in my warning log and a pattern emerged. Almost all of attempts originated in China – no surprise there. But, what is going on that all of a sudden I see this increase and is it happening all over or did my poor little computer let down it’s guard long enough to get noticed?

Tue Mar 7, Reuters, in an article titled “Cyber criminals stepping up targeted attacks”

“China is also fast turning into a major source of botnet attacks likely due to the rapid growth in broadband Internet connections there, the report said.
During the last six months of the year, botnet attacks originating in China soared 153 percent, which is 72 percentage points above the average increase, the report said.

I read an article a while back (can not remember where, sorry) that made a case supporting the idea that this problem would grow in proportion to the Chinese governments censorship of it’s citizens internet access. The more desperately the citizens wanted to find a way past government controls on access more botnets would be created. More firewall warnings and infections of Western computer systems would lead to the Western worlds blocking of Chinese IP addresses. And round and round it would go. A firewall of it’s own.

Pay Off Your Credit Card and Homeland Security Gets Notified

Here is an example I came across about Homeland Security and changes in the Bank Privacy Act and how they are keeping us safer. It seems if you pay off a debt, you are a security threat. Pay too much and you could raise the alarm.

PROVIDENCE, R.I. — Walter Soehnge is a retired Texas schoolteacher who traveled north with his wife, Deana, saw summer change to fall in Rhode Island and decided this was a place to stay for a while.

So the Soehnges live in Scituate now and Walter sometimes has breakfast at the Gentleman Farmer in Scituate Village, where he has passed the test and become a regular despite an accent that is definitely not local.

And it was there, at his usual table last week, that he told me that he was “madder than a panther with kerosene on his tail.”

He says things like that. Texas does leave its mark on a man.

What got him so upset might seem trivial to some people who have learned to accept small infringements on their freedom as just part of the way things are in this age of terror-fed paranoia. It’s that “everything changed after 9/11” thing.

But not Walter.

“We’re a product of the ’60s,” he said. “We believe government should be way away from us in that regard.”

He was referring to the recent decision by him and his wife to be responsible, to do the kind of thing that just about anyone would say makes good, solid financial sense.

They paid down some debt. The balance on their JCPenney Platinum MasterCard had gotten to an unhealthy level. So they sent in a large payment, a check for $6,522.

And an alarm went off. A red flag went up. The Soehnges’ behavior was found questionable.

And all they did was pay down their debt. They didn’t call a suspected terrorist on their cell phone. They didn’t try to sneak a machine gun through customs.

They just paid a hefty chunk of their credit card balance. And they learned how frighteningly wide the net of suspicion has been cast.

After sending in the check, they checked online to see if their account had been duly credited. They learned that the check had arrived, but the amount available for credit on their account hadn’t changed.

So Deana Soehnge called the credit-card company. Then Walter called.

“When you mess with my money, I want to know why,” he said.

They both learned the same astounding piece of information about the little things that can set the threat sensors to beeping and blinking.

They were told, as they moved up the managerial ladder at the call center, that the amount they had sent in was much larger than their normal monthly payment. And if the increase hits a certain percentage higher than that normal payment, Homeland Security has to be notified. And the money doesn’t move until the threat alert is lifted.

Walter called television stations, the American Civil Liberties Union and me. And he went on the Internet to see what he could learn. He learned about changes in something called the Bank Privacy Act.

“The more I’m on, the scarier it gets,” he said. “It’s scary how easily someone in Homeland Security can get permission to spy.”

Eventually, his and his wife’s money was freed up. The Soehnges were apparently found not to be promoting global terrorism under the guise of paying a credit-card bill. They never did learn how a large credit card payment can pose a security threat.

But the experience has been a reminder that a small piece of privacy has been surrendered. Walter Soehnge, who says he holds solid, middle-of-the-road American beliefs, worries about rights being lost.

“If it can happen to me, it can happen to others,” he said.
