                Most bullets make small sonic booms when flying through the air, which to our ears sound like a loud, distinct "crack!" Now the commandos want to be sneakier with slower, quieter bullets. In its latest round of small-business solicitations, the Pentagon's Special Operations Command, or SOCOM, is seeking out subsonic ammunition. The reason, according to the solicitation, is to "provide superior covert and stealth capabilities" for not only the military, but police forces and the Department of Homeland Security. The Pentagon has one idea about how to build a better subsonic bullet. One solution could be using "polymer cased ammunition". The Pentagon is somewhat vague about how this will work. Special forces 'want to be sneakier with slower, quieter bullets'.The quieter bullets would travel slowly enough not to break the sound barrier. Subsonic bullets pose a greater risk of jamming.

How to Devise Passwords That Drive Hackers Away

                                                 

                According to statistics, hacking into computers and such has risen at an all time high. More and more people are hacking into e-mails, blogs, social websites, etc. This article will prevent statistics from rising anymore. Things to remember while making passwords for websites:

Forget the Dictionary: Do not use basic words or even your simple name.

Never use the same password twice: Doing so can increase your chances of getting hacked because if a person hacks into one account they can hack into another.

 

Come up with a passphrase: The longer your password, the longer it will take to crack. A password should ideally be 14 characters or more in length if you want to make it untraceable.

Store your passwords securely: Doing so will lessen the chances of a hacker finding your passwords list which will obviously prevent hacking into your sites.

     Self-driving cars now legal in California

                                                              Click here for Tech Article

                                 

California is the latest state to allow testing of Google's self-driving cars on the roads, though only with a human passenger along as a safety measure.

The cars use a combination of technologies, including radar sensors on the front, video cameras aimed at the surrounding area, various other sensors and artificial-intelligence software that helps steer. Google is the most visible company working on these types of vehicles, but similar projects are under way at other organizations, including Caltech.

There have been no accidents while the cars were controlled by the computer. The only documented accident with one of the Google vehicles was a fender bender that took place while a human was in control.

People hope to legally have self driving cars on the road in five years or less.

           A bra that could detect cancer

                                                                                  Click Here for Article!!

First Warning Systems has just recently created a bra that just might detect cancer. The bra is equipped with sensors that detect temperature changes in breast tissue. According to the company's website, the data generated by the sports bra ca predict the presence of breast cancer with 90% specificity and sensitivity. Women must wear it for at least 12 hours so the bra can accumulate enough information for stable temperature changes. It then splits up the results: if it is benign, normal, or suspected. This bra is also a great fashionable fit for athletes!
