Aliens Hack Voyager 2?

IT left Earth 33 years ago, now it's claimed the Voyager 2 spacecraft may have been hijacked by aliens after sending back data messages NASA scientists can't decode.NASA installed a 12-inch disk containing music and greetings in 55 languages in case intelligent extraterrestrial life ever found it.But now the spacecraft is sending back what sounds like an answer: Signals in an unknown data format!The best scientific minds have so far not been able to decipher the strange information - is it a secret message?

Herb Alpert

Alpert set up a small recording studio in his garage and had been overdubbing a tune called "Twinkle Star", written by Sol Lake, who would eventually write many of the Brass' original tunes. During a visit to Tijuana, Mexico, Alpert happened to hear a mariachi band while attending a bullfight. Following the experience, Alpert recalled that he was "inspired to find a way to musically express what [he] felt while watching the wild responses of the crowd, and hearing the brass musicians introducing each new event with rousing fanfare." Alpert adapted the trumpet style to the tune, mixed in crowd cheers and other noises to create ambiance, and renamed the song, "The Lonely Bull". He paid out of his own pocket to press the record as a single, and it spread through radio DJs until it caught on and became a Top Ten hit in 1962.

Incorrect predictions

Sometimes, someone says something that turns out to be an incorrect prediction. In hindsight, however, the people who said these things may have had good reasons for thinking they were right. Sometimes when they try and explain their way out of it, they make it even worse:"There is no reason for any individual to have a computer in his home." - Ken Olson, president, chairman and founder of Digital Equipment Corporation (DEC)This quote was from a talk given to a 1977 World Future Society meeting in Boston. This is widely quoted but Olsen claims it is taken out of context, that he was not referring to personal computers but to a household computer that would control the home.

Happy Birthday RAM

The structure consisted of a plane made of wires and magnetic rings called cores. Each ring contained one bit of data. Every bit on the memory plane could be accessed with a single read-and-write cycle.In short, magnetic core memory was the first random access memory that was practical, reliable and relatively high-speed. The time it took to request and retrieve information from memory was a microsecond -- hundreds of thousands of times slower than memory today, but nonetheless a magnificent achievement in the 1950s.

NASA Orion Can Abort

NASA's Pad Abort 1 flight test, a launch of the abort system designed for the Orion crew vehicle, lifted off at 9 a.m. EDT Thursday at the U.S. Army's White Sands Missile Range (WSMR) near Las Cruces, N.M. The flight lasted about 135 seconds from launch until the crew module touchdown about a mile north of the launch pad.The flight was the first fully-integrated test of this launch abort system design. The information gathered from the test will help refine design and analysis for future launch abort systems, resulting in safer and more reliable crew escape capability during rocket launch emergencies.

What Business is Wall Street In?

The best analogy for traders ? They are hackers. Just as hackers search for and exploit operating system and application shortcomings, traders do the same thing. A hacker wants to jump in front of your shopping cart and grab your credit card and then sell it. A high frequency trader wants to jump in front of your trade and then sell that stock to you. A hacker will tell you that they are serving a purpose by identifying the weak links in your system. A trader will tell you they deserve the pennies they are making on the trade because they provide liquidity to the market.

A Study of EverQuest

Almost everyone who has taken an introductory psychology course in high school or college has heard of B.F. Skinner. Skinner is an important figure in Behaviorism, and developed a learning theory known as Operant Conditioning. Skinner claimed that the frequency of a given behavior is directly linked to whether it is rewarded or punished. If a behavior is rewarded, it is more likely to be repeated. If it is punished, it becomes suppressed. This deceptively simple and straight-forward theory may explain why EverQuest is so addictive.

Jpeg Exif Autorotate

Adds right click menu items to Windows for folders and photo files (.jpg, .jpeg). These allow you to effortlessly and losslessly rotate single images, all images in a folder, all images in a folder and in all its subfolders according to the EXIF orientation metadata (stored in photos by most digital cameras). This way, you never have to rotate photos by hand.

Batch Picture Resize

The tool will resize JPG images and save them next to the originals. Names of the new pictures will be based on the original names, with a suffix indicating their size. For example, the resized version of MyPhoto.jpg will be called MyPhoto-400.jpg, where the number 400 indicates the size of the picture.
