10 technical laws on which live online

From the laws of thermodynamics to the Murphy law, the laws define and describe the world around us - and the technique they also explain everything from how your browser is up to the reasons why people do stupid things just to laugh.

The next ten laws explain the popularity of Facebook, what happens to your smartphone, and why there are images of Sponge Bob that you really (really!) Does not want to see.

1. Law KrayderaZakon Kreider is Moore's Law for disk drives: vice president of scientific development of Seagate in 2005, said that the recording density on magnetic disks doubles approximately every eighteen months.

It also means that the cost of data storage is reduced by half every eighteen months, enabling online services offer us more space to store our data, without raising the price. It should be noted however, that the SSD does not subject to the law Kreider: because they are solid, they apply more than Moore's Law.

2. Law VirtaVy ever wondered why your seventy-three-core super-modern computer does not behave much more efficiently in everyday tasks, compared with the computer of ten years ago? Niklaus Wirth is set, and in 1995, he noted that "Soft becomes slower much faster than hard becomes more rapid." Wirth's Law erroneously attributed to Larry Page of Google and Bill Gates of Microsoft.

3. Law MetkalfaZakon 3Com founder Bob Metcalfe originally described fax machines and computers, but it applies equally to the Internet and Internet services like Facebook: the value of a telecommunications network is proportional to the square of the number of users of the system. Social network with one user is absolutely useless; with millions of users, it becomes almost indispensable.

4. Rule 34 "If there is something there, then somewhere there are porn with this thing. No exceptions. " It needless generally believed to be gone from the now defunct online comics zoomout.co.uk, but it is possible that comics took it out of the anonymous mailing of "rules of the Internet." Since then, it has been somewhat adapted: if you can not find a porn version of anything is just to tell you about this online and it immediately becomes the motive for the - as it describes the Urban Dictionary - «crazy Japanese hentai artists' paint it.

5. Goodhart's Law "Any observed phenomenon tends to experience a collapse as soon as it will be to make efforts to control or measure it," said Professor Goodhart Charlie in 1975: in other words, if you set yourself any targets and try to do something good, people always find a way to use these goals are not improving anything that makes all your efforts as a whole meaningless.

The best example of this principle is Google: when he began to use inbound links in PageRank, to make the search more useful, spammers began creating farm links and spam blogs to artificial inflation of PageRank index their sites.

6. Law FittsaZakon Fitts is extremely important for the development of user interfaces, from the touch screen applications to the buttons on the website. Paul Fitts system studied human-computer interaction and found that the time spend on something to reach for something and push it, is a function of how far it is located and what size it is.

Especially brightly it can be seen in smartphones - navigate some websites almost neprisposoblen for use on small screens, while the on-screen keyboard in iOS used Fitts's Law, trying to predict what character you type the following, and making it a zone press longer.

Fitts's Law is used in all types of user interfaces, including on-screen keyboard in iOS

7. Law AmaryRoy Amara was a scholar and president of the California Institute of the Future, and the law encourages us to think about new technologies in the long term: "We tend to overestimate the effect of technology in the short term and underestimate the long-term." Online reaction to Apple products perfectly illustrates both sides of the law Amarah.

8. Law LinusaSuschestvuet two different law Linus: one says that "If there is enough eyes, all bugs will be found" - throw enough smart people on anything, and they will find a way to fix it, but we prefer a different law that Linus Torvalds has described in 2001 in his book "The Hacker Ethic and the Spirit of the Information Age": the motivation for anything falls into three categories, "survival", "social life" and "entertainment". This explains why some people take part in open-sorsnyh projects, and why others join Anonymous (famous international group of high-hackers; approx. Mixednews) or do stupid things just for the "lulz».

9. Law MuraVtoroy most famous technical law actually does not say that computing power doubles every two years - the original Moore's Law states that the number of transistors that can be placed on an integrated circuit doubles every year, which is not quite the same and Moore changed his assessment from one to two years in 1975 - and despite the many predictions of its demise, he remained fairly reliable indicator for several decades. Today it is a useful indicator for the future of smartphones and SSD.

Moore's Law suggests that today's four-core processors seem terribly outdated in a few years

10. Godwin's Law "On a long enough period of time the likelihood that some of the participants on-line discussion will make a comparison of something with Hitler or Nazis approaches unity." This is the Law of Nazi analogies Godwin, as defined by the American lawyer and writer Mike Godwin in 1990. It is generally assumed that when the online discussion is "Zagodvinennoy" she finished, but this applies only in the case if the comparison to Nazis or Hitler used not in an ironic way. Although it is a fun idea, Godwin made it relatively serious note: "I would like to see those who glibly compare someone to Hitler or the Nazis, remembered the Nazi crimes».
