The Usability of Passwords (by @baekdal) #tips Security companies and IT people constantly tells us that we should use complex and difficult passwords. This is bad advice, because you can actually make usable, easy to remember and highly secure passwords. In fact, usable passwords are often far better than complex ones. So let's dive into the world of passwords, and look at what makes a password secure in practical terms. Update: Read the FAQ (updated January 2011) Update - April 21, 2011: This article was "featured" on Security Now, here is my reply! How to hack a password The work involved in hacking passwords is very simple. Asking: Amazingly the most common way to gain access to someone's password is simply to ask for it (often in relation with something else). When is a password secure? You cannot protect against "asking" and "guessing", but you can protect yourself from the other forms of attacks. The measure of security must then be "how many password requests can the automated program make - e.g. per second". Like these: It takes:
The WWW Virtual Library Biostamp temporary tattoo wearable electronic circuits by MC10 Materials scientist John Rogers and his firm MC10 have developed flexible electronic circuits that stick directly to the skin like temporary tattoos and monitor the wearer's health. The Biostamp is a thin electronic mesh that stretches with the skin and monitors temperature, hydration and strain. Rogers suggests that his "epidermal electronics" could be developed for use in healthcare to monitor patients without tethering them to large machines. Not only would this be more convenient, but the results could be more accurate if patients were examined in their normal environment doing usual activities rather than on the hospital ward. Other applications could include a patch that lets an athlete know when and how much to hydrate for peak performance, or one that tells you when to apply more suncream. MC10 overcame the rigidity of normal electronic components made from brittle silicon-based wafers by printing them in very small pieces, arranged in wavy patterns.
Data.ti | Revista de TI para empresa | Actualidad - Software - TIC www.menshealth.com/mhlists/Most-Efficient-Workout/printer.php Muscles are funny things. They respond to just about any type of training, as long as it's hard and as long as it's not the same damn thing you've always done. That's the beauty of density training: It's a whole lot of stuff you haven't tried yet. And best of all, it'll hit your major muscles in a fraction of the time. Unsure what exercises you should focus on? THE PLAN: Do three density workouts a week, with at least 1 day off in between. Pushup Assume a pushup position, with your hands slightly beyond shoulder-width apart, feet together, and body in a straight line from head to ankles. Reverse Lunge and 1-Arm Press Stand holding a pair of dumbbells next to your shoulders. Inverted Row Lie underneath a secured bar. Prisoner Squat Place your fingers on the back of your head, pull your elbows and shoulders back, and stand with your feet shoulder-width apart. Explosive Pushup Perform a basic pushup.

Nanoengineers invent new biomaterial that more closely mimics human tissue Thursday, May 26, 2011 A new biomaterial designed for repairing damaged human tissue doesn’t wrinkle up when it is stretched. The invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue.

A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The new biomaterial was created using a new biofabrication platform that Chen is developing under a four-year, $1.5 million grant from the National Institutes of Health. "We are also exploring other opportunities," said Chen. Shape turned out to be essential to the new material's mechanical property.
Inventor of the Week Rubber Bandits® A seemingly simple idea sometimes can become an incredibly successful, mass-market product that makes life a little bit easier for millions. Such is the case with Rubber Bandits®, oversized rubber bands equipped with tear-resistant, waterproof labels, created by self-described “idea czar” Adrian Chernoff in 2004. Chernoff was born in 1971 and grew up in Albuquerque, New Mexico. In 2004, he received a phone call from his mother who had heard of a competition held by the office supply store chain Staples®. Chernoff didn’t have much time, but he told his mother he would enter. Chernoff submitted his idea and made it through several rounds of competition, continually improving his design with each round. Meanwhile, Chernoff left GM to start his own ideas company, 2 Smart + 1, where he serves as CEO. Chernoff holds over 75 patents with more than 20 others pending and has been recognized with a number of honors for his achievements. [September 2008]

Theta Wave Brain Synchronization This is a replication of a Theta wave entrainment rhythm first created by scientists in the 1960s to lull patients into a deep, colorful, creative dream state. Listen to it for 10 minutes, longer if you can. The longer it plays, the deeper you’ll go. So go. How It Works The human brain produces different levels of electrical activity depending on the amount of information it is processing. Throughout the day, the brain lingers between four different types of brainwave patterns: Beta (12 -30 Hz): the normal, awake consciousness associated with busy tasksAlpha (8 – 12 Hz): the relaxed and reflective state, like those induced by closing the eyes during waking hoursTheta (4 – 7 Hz): a very relaxed state associated with meditation and some sleep statesDelta (3 and under Hz): deep, dreamless sleep Theta waves (at around 4 to 7 Hz) are the sweet spot for many brain functions.
'First Comprehensive Gene Map' of the Brain Shows How Genes Express Themselves Neurologically The Allen Institute for Brain Science has completed what it is calling the first comprehensive gene map of the human brain as part of its development of the Allen Human Brain Atlas, a public resource that it hopes will accelerate clinical understandings of how the human brain works. The genetic mapping of two human brains showed a striking 94 percent similarity between the two, which could help researchers establish patterns and otherwise figure out in which parts of our brains to look for different expressions of genetic differences. The idea behind the brain atlas is to develop a tool that researchers can access to determine how the genome is expressed in the brain, a process which is--needless to say--complex. Over four years, the ABI crunched more than 100 million data points to pinpoint 1,000 different anatomical sites in the brain that exhibit particular gene expression. That last part is key for research purposes. [Allen Institute for Brain Science]
What's the matter with Spain? 7 December 2011Last updated at 15:42 By Laurence Knight Business reporter, BBC News The next Spanish government will find itself on the horns of a nasty economic dilemma Spain's recently-elected Prime Minister, Mariano Rajoy, faces a potentially unsolvable economic dilemma. He may also face a major financial crisis, if the latest plan to rescue the euro fails. Only last week Spain was staring into the same financial abyss that had already swallowed Greece, Portugal and the Irish Republic, and was sucking in Italy. That was before markets came alive with talk of an imminent bailout of Italy by the European Central Bank. The Spanish government's cost of borrowing money on the financial markets for 10 years - a popular barometer of lender fear - peaked at a rate of 6.7% before falling back on the rumours. That's close to the level where other eurozone governments turned to their neighbours for a bailout. In comparison, Germany only has to pay an interest rate of 2.1%. Off-message Breaking the rules
