The Hubble Internet audit is a project to discover "black holes in the Internet" where traffic won't route:
Katz-Bassett has been working on a project called Hubble, a system that apparently is able to track what he refers to as information black holes. These are situations where a path between two computers does exist, but messages - a request to visit a Web site or an outgoing e-mail - get lost along the way. Katz-Bassett has published a Hubble map that enables users to monitor such black holes worldwide or simply type in a network address to check its status.
To determine a network status, Hubble sends test messages “around the world” to look for computers that can be reached from some but not the entire Internet, a situation that is described as “partial reachability”. Katz-Bassett said that short communication blips are ignored. However, if a problem surfaces in two consecutive 15-minute trials, it is listed as a “problem”. The research team found that more than 7% of computers worldwide experienced this type of error at least once during a three-week period in fall of 2007.
Teams of researchers are developing sesame seed-size neuro-implants that detect brain activity that signals depression and then deliver targeted electrical zaps to elevate your mood. It’s very early days in the science and technology but recent studies suggest that we’re on the path. Links to scientific papers below. Fortunately, the goal is to develop tools […]
In the 1960s, when Scientific American copy editor Michael J. Battaglia was 15, he had a chemical romance with the periodic table. In fact, Battaglia was so fascinated by the basic substances of our universe that he tried to collect ’em all (at least the 104 elements that science knew about at the time.) From […]
Aren’t they beautiful? Here’s how ‘ghost apples’ formed on this apple tree in West Michigan.
Breaking into the indie video game market may be easier than you think. It all starts with an idea, and then it’s a matter of finding the right development platform to bring it to life. No matter what that platform is, it’s a good bet that it’s covered in the 2019 Game Dev & Design […]
Learning a new language like Spanish doesn’t have to be hard. Either you can buy a ticket to a Spanish-speaking country, immerse yourself in the culture and pick it up intuitively – or you can do it from the comfort of the chair you’re in right now by logging on to Rocket Spanish. There are […]
