Styleguide - Style guides for Google-originated open-source projects. Styleguide. The Internet map. The map of the Internet Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface.

The Internet map

Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other. Charges and springs To draw an analogy from classical physics, one may say that websites are electrically charged bodies, while links between them are springs. Also, an analogy can be drawn from quantum physics. Anyway, the real algorithm of plotting The Internet map is quite far from the analogies given above. Semantic web The Internet Phenomenon.

Although there is still a long way to go before it’s ready for Firefox proper, switching to an opt-in, "click-to-play" approach for plugins could help make Firefox faster, more secure, and a bit easier on the laptop battery. A very early version of the "click-to-play" option for plugins is now available in the Firefox nightly channel. Pluto Scarab — Hash Functions. SMAC - Publications. Anatomy of Facebook.

Metcalfe's law. Two telephones can make only one connection, five can make 10 connections, and twelve can make 66 connections.

Metcalfe's law

Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2). First formulated in this form by George Gilder in 1993,[1] and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe's law was originally presented, circa 1980, not in terms of users, but rather of "compatible communicating devices" (for example, fax machines, telephones, etc.)[2] Only more recently with the launch of the Internet did this law carry over to users and networks as its original intent was to describe Ethernet purchases and connections.[3] The law is also very much related to economics and business management, especially with competitive companies looking to merge with one another.
