The National Radio Quiet Zone
‘In these parts, a pay phone is a visitor’s best option for reaching the rest of the world. A cell phone signal is an hour away by car. Wifi is forbidden. The radio plays nothing but static. And other than the occasional passing pickup truck whose driver offers a wave, it’s dead silent.
‘Seemingly off the beaten path, this community of fewer than two hundred residents is the heart of the National Radio Quiet Zone, a 13,000-square-mile area where state and federal laws discourage the use of everyday devices that emit electromagnetic waves. The quiet zone aims to protect sensitive radio telescopes at the National Radio Astronomy Observatory, as well as a nearby Naval research facility, from man-made interference. This silence enables the observatory to detect energy in outer space that is equivalent to the energy emitted by a single snowflake hitting the ground…’

‘A new algorithm designed at the University of Toronto has the power to profoundly change the way we find photos among the billions on social media sites such as Facebook and Flickr. This month, the United States Patent and Trademark Office will issue a patent on this technology.
‘Developed by Parham Aarabi, a professor in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering, and his former Master’s student Ron Appel, the search tool uses tag locations to quantify relationships between individuals, even those not tagged in any given photo…’
High IQd but Not Smart
Our IQs Are Climbing, But We’re Not Getting Smarter
‘Does the rise in IQ scores over the past century mean people are getting smarter? Since the beginning of the twentieth century, IQ scores around the world have been increasing at a rate of around three points per decade, leaving intelligence researchers puzzling over whether historical gains in IQ—known as the “Flynn effect”—reflect an increase in general intelligence or something else, be it better education, better nutrition or even bigger brains. A new paper published in the journal Learning and Individual Differences (2014) may have the answer: We’re getting better at taking tests…’
Self-Replicating USBs Spread Software Faster than an Internet Connection
‘This guy has devised a cheap and simple way to transmit large software packages without using the internet and at rates that eclipse all but the best internet connections.
‘His idea is simple: create a self-replicating bootable USB stick that holds an operating system and any software that needs to run on it. This stick is self-replicating in the sense that it can copy its contents to another USB stick with just a few clicks and no expert knowledge.
‘And that’s exactly what Monteil has done. He has written a script that clones the contents of one USB stick to another of sufficient size. It copies only the designated software, without copying any personal data on the first stick (except for any stored in a special /shared folder). It also preserves any data already on the second stick…’
