Is it really that big business of cybercrime?

Cybercrime moves more money than drug trafficking worldwide. " The phrase comes from the manager of an Internet security company, so you have to grab with tweezers, but is part of a widespread belief that it has become a mantra by all indications, cybercrime move a figure of up to one trillion (European, American trillion) dollars a year, becoming in fact one of the largest illicit business, over the drug or arms trafficking. However, data may be flawed from the beginning, as claimed by two researchers from Microsoft in a New York Times.
"For 15 years, cybercrime has evolved from a dark activity to become a global security concern, they say Florencio and Cormac Herley Dinei article 'The cyber crime was not tal'-but there is something wrong with this picture: Structurally, the economy of cybercrime as spam and steal passwords is the same as fishing.Economists have long established common access resources represent a bad business opportunity. "
The calculation error when assessing cybercrime come provoked, according to the authors, by a statistical aberration: the losses to consumers cybercriminals are extrapolated to the general population from surveys from a few cases which tend to be positive: ie, take the part for the whole and multiply individual cases to the general population. For example, "if you ask 5,000 people for their loss due to cybercrime and extrapolated to 200 million people, that means that every dollar becomes 40,000. If a single respondent blamed bogus losses by $ 25,000, this amounts to 1,000 million dollars to the final estimate. "
In fact, this statistical aberration happens in any survey that involves selecting a group of people. One respondent in an election poll will be "responding" for several thousands of citizens who share the same profile and home that has a people meter "means" to 10,000 homes when and TV. For Florencio and Herley denouncing the added problem is that 90% of the estimates from a study of FTC were made from only one or two answers: "two participants added to the estimated 37,000 million losses."

The Histomap: 4,000 years of world history at a glance

Which came first, the Pyramids of Giza or the Great Wall in China? What wasmore, the Roman Empire or the Greek Empire? Is it more important to the coronation of Charlemagne or the assassination of Abraham Lincoln?

May be some difficulty involving questions of history, but certainly respond at a glance with the perspective offered by the wonderful logarithmic map of John B.Spark "The Histomap: Four Thousand Years of World History", a representation of the history of civilized man remains cinnamon as computer graphics classinstrument.

In very simple terms and general map shows visually the activities and behavior of all races on the planet for 4,000 years.

And is that John B. Spark created this map nothing more nor less than in 1931 toshow a new way of representing events over time accurately using a logarithmictime line, ie a timeline established according to a scale where everything has a place in the form and dimensions.

The logarithmic terms have also been used in studies to anticipate the future to justify the idea of ​​a possible technological singularity within a jug of centuries.

But looking back the same way, you can read the story through color map to compare the facts and events that took place in different parts of the world during the same period, or read the Histomap to chart the rise and fall of peoples, cultures, empires and countries.

Of course, since 1931 it has rained a lot and would be updated, and correctseveral errors fruit of their age. But you can understand at a glance that a civilization can make its way on the map, one has to lose dramatically.It is the fate of the expansion of the world and this is his criminal record, history of history itself.
