PIN/Password Analysis Shows That We’re Predictable

August 6th, 2013

Computer SecurityThe author of the linked article accumulated a database of hacked PINs and numeric passwords, then analyzed it to see what patterns emerged. Here are some of the highlights:

  • 20% of all PINs use just five different numbers: 1234, 1111, 0000, 1212, and 7777.
  • The fourth most popular seven-digit password is 8675309. (Wait for it…)
  • Using a year in the form 19XX is a bad idea.
  • The least used PIN is 8068.
  • Including 007, 420, and 69 may seem like a neat idea, but they turn out to be quite common.
  • Numbers made from drawing lines or patterns on the keypad are also popular.

Initial Impressions of Google Glass are Negative

May 4th, 2013

Google LogoBusiness Insider has an article listing the problems with Google Glass, based on reviews by others. Most of these issues can be fixed, but the author was unable to find anyone with a compelling reason to actually use Google Glass—which may be the primary factor in whether or not the technology is adopted by the general public.

Calvin and HobbesSome Calvin and Hobbes fans have made a fake trailer for a movie where Calvin is now an adult and his imagination is even more powerful—but it’s turning darker. And all I can say is “Wow.”

What Happens When You Wring Out a Washcloth in Zero Gravity

April 20th, 2013

ISS Commander Chris Hadfield was asked by high school students to demonstrate what happens when you wring out a washcloth in zero gravity. The result is pretty cool and is all about surface tension!

Only in America: eBay Seller Sues Over Negative Feedback

April 17th, 2013

GavelSo you’re an eBay seller and have received negative feedback from a customer. You do what you can to resolve the problem, but the buyer refuses to remove the feedback. What can you do? Well, if you’re in the United States then you file a lawsuit. The seller, Med Express, is suing the the buyer, Amy Nicholls, for slander.

I’m on the buyer’s side, although I probably would have only given a “neutral” rating. Having to make a trip to the post office to pay postage due is a always a pain.

Update (2013-04-19): Because of all the publicity, the lawsuit is being dropped. But research shows that Med Express has a history of doing this.

An Astounding Number of Vulnerable Internet Devices

April 6th, 2013

Computer SecurityA computer researcher wanted to map all 3.6 billion of the Internet’s usable IPV4 IP addresses, to see which ones are actually being used and to determine where the devices are physically located. This would be quite a task for a single computer, so he created a botnet with 420,000 zombie devices to do the task for him. What I find most interesting, however, is how he managed to compromise those devices. He simply tried to connect to each one with the following four username/password combinations:

  • admin/admin
  • root/root
  • admin/(blank)
  • root/(blank)

No kidding. That’s all it took.

For the more technically minded, the paper says that “the vast majority of all unprotected devices are consumer routers or set-top boxes.” So just for kicks, I telneted to my router and found that the admin/admin combination worked. Fortunately it’s configured such that remote telnet is disabled—so I was not part of this experiment. The paper goes on to say that the 420,000 number is for the devices they turned into zombies, and that the actual number of vulnerable machines is about four times that many.

Making Fuel From Carbon Dioxide in the Atmosphere

April 6th, 2013

Recycle LogoResearchers at the University of Georgia have created genetically-modified bacteria that take carbon dioxide from the atmosphere to make carbohydrate chemicals. (Note that hydrogen gas was added for the experiment.) From the article: “We can take carbon dioxide directly from the atmosphere and turn it into useful products like fuels and chemicals without having to go through the inefficient process of growing plants and extracting sugars from biomass.”

I am a firm believer that technology can solve many of our problems. And this, should it prove to be economically viable in large scales, is a good example of just that.

Internet Withdrawal is Real

March 31st, 2013

InternetFrom the linked article: “The researchers found that people who habitually surf the Internet for long periods at a time suffer higher incidence of ‘negative moods’ after they stopped surfing, leading to addiction-like urge to return to the Web to alleviate or lift the negative mental states. The researchers warned that surfing the Internet for long stretches of time can result in withdrawal symptoms similar to those that drug abusers experience.”
