Why passwords have never been weaker—and crackers have never been stronger

In late 2010, Sean Brooks received three e-mails over a span of 30 hours warning that his accounts on LinkedIn, Battle.net, and other popular websites were at risk. He was tempted to dismiss them as hoaxes—until he noticed they included specifics that weren't typical of mass-produced phishing scams. The e-mails said that his login credentials for various Gawker websites had been exposed by hackers who rooted the sites' servers, then bragged about it online; if Brooks used the same e-mail and password for other accounts, they would be compromised too. The warnings Brooks and millions of other people received that December weren't fabrications. "The danger of weak password habits is becoming increasingly well-recognized," said Brooks, who at the time blogged about the warnings as the Program Associate for the Center for Democracy and Technology. The ancient art of password cracking has advanced further in the past five years than it did in the previous several decades combined.

Cyber Security Wiki The Science of Word Recognition About fonts > ClearType The Science of Word Recognition or how I learned to stop worrying and love the bouma Kevin LarsonAdvanced Reading Technology, Microsoft CorporationJuly 2004 Introduction Evidence from the last 20 years of work in cognitive psychology indicate that we use the letters within a word to recognize a word. This paper is written from the perspective of a reading psychologist. The goal of this paper is to review the history of why psychologists moved from a word shape model of word recognition to a letter recognition model, and to help others to come to the same conclusion. I will start by describing three major categories of word recognition models: the word shape model, and serial and parallel models of letter recognition. Model #1: Word Shape The word recognition model that says words are recognized as complete units is the oldest model in the psychological literature, and is likely much older than the psychological literature. characters Model #2: Serial Letter Recognition

Species Counterpoint An Introduction to Species Counterpoint COUNTERPOINT may be briefly defined as the art of combining independent melodies. In figure 1 the lower melody is harmonized by one a third higher - such an arrangement of the voices could be regarded as counterpoint, but there is little or no independence between the parts; for example there is no dissonance between the voices, and both rise and fall together in parallel. However, the arrangement in figure 1a demonstrates much greater independence between its two voices, with movement in one part while the other halts, divergence in the melodic direction of the parts, and with at least some occurrence of dissonance. J.J.Fux's Gradus Ad Parnassum is the classic text dealing with species counterpoint and fugue; it presents a set of rules for writing in the style of 16th century vocal composition (i.e. There are several rules governing melodic movement in the counterpoint; these are common to all five species. First Species An example from Gradus

How Can I Tell If Someone Is Lying To Me? (Infidelity) VideoJug presents a short guide explaining exactly how you can tell if someone is lying. With advice from our body language expert Judi James, never before has been so easy to see if someone is lying to you! Step 1: No body movement Little or no body movement occurs when the pressure of the lie makes the liar worry about their body language, so some will stop moving all together. Step 2: Exaggerated body movement Some liars do the opposite. Step 3: Stress gestures Lying makes people stressed and this comes across in their body language with strange gestures such as scratching, itching and twitching. Step 4: Eye contact Eyes are a great giveaway. Step 5: Eye movement We move our eyeballs to stimulate different parts of the brain. Step 6: Nose touching This is a typical sign of lying. Step 7: Mouth or face covering This is a childish bit of body language, but some still desire to cover their face, particularly when telling the part of the lie they are most worried about.

Voting Methods 1. The Problem: Who Should be Elected? The central question of this article is: Given a group of people faced with some decision, how should a central authority combine the individual opinions so as to best reflect the “will of the group”? A complete analysis of this question would incorporate a number of different issues ranging from central topics in political philosophy (e.g., how should we define the “will” of the people? I start with a concrete example to illustrate the type of analysis surveyed in this article. For this example, assume that each of the voters has one of four possible rankings of the candidates. Read the table as follows: Each column represents a ranking in which candidates in lower rows are ranked lower. One candidate who, at first sight, seems to be a good choice to win the election is candidate A. Of course, 13 people rank A last, so a much larger group of voters will be unsatisfied with the election of A. Candidate C should win. Candidate B should win. 2. 3. 4.

Neural Network Tutorial Introduction I have been interested in artificial intelligence and artificial life for years and I read most of the popular books printed on the subject. I developed a grasp of most of the topics yet neural networks always seemed to elude me. Sure, I could explain their architecture but as to how they actually worked and how they were implemented… well that was a complete mystery to me, as much magic as science. I bought several books on the subject but every single one attacked the subject from a very mathematical and academic viewpoint and very few even gave any practical uses or examples. So for a long long time I scratched my head and hoped that one day I would be able to understand enough to experiment with them myself. That day arrived some time later when - sat in a tent in the highlands of Scotland reading a book - I had a sudden blast of insight. The C++ source code for the tutorial and a pre-compiled executable can be found here. 2 3 4 5 6 7 8 Next Home
