Types of websites

There are many varieties of Web sites, each specializing in a
particular type of content or use, and they may be arbitrarily classified in any number of ways. A few such classifications might
include:



Some websites may be included in one or more of these categories.
For example, a business website may promote the business's products,
but may also host informative documents, such as white papers. There are also numerous sub-categories to the ones listed above. For example, a porn
site is a specific type of eCommerce site or business site (that is, it
is trying to sell memberships for access to its site). A fan site may be a dedication from the owner to a particular celebrity.

La navaja para estúpidos maliciosos

Hanlon's razor [La navaja de Hanlon]
Never attribute to malice that which can be adequately explained by stupidity.
Also worded as:
Never assume malice when stupidity will suffice.
Nota bene:
A similar quotation appears in Robert A. Heinlein's 1941 short story Logic of Empire
("You have attributed conditions to villainy that simply result from stupidity"); this was noticed in 1996 (five years before Bigler identified the Robert J. Hanlon citation) and first referenced in version 4.0.0 of the Jargon File [4], with speculation that Hanlon's Razor might be a corruption of "Heinlein's Razor." "Heinlein's Razor" has since been defined as variations on Never attribute to malice that which can be adequately explained by stupidity, but don't rule out malice. or ... but keep your eyes open.
A variant, Grey's Law (influenced, no doubt, by Clarke's third law), posits "Any sufficiently advanced incompetence is indistinguishable from malice."
["Cualquier suficientemente avanzada incompetencia es indistinguible de malicia"]

La navaja para estúpidos maliciosos:
Nunca atribuyas a la malicia lo que pueda ser adecuadamente explicado con la estupidez
Lo que puede leerse:
Nunca asumas malicia cuando baste la estupidez

Clarke's three laws

Clarke's three laws
  1. When a distinguished but elderly scientist states that something is
    possible, he is almost certainly right. When he states that something
    is impossible, he is very probably wrong.
  2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
  3. Any sufficiently advanced technology is indistinguishable from magic.
  4. For every expert there is an equal and opposite expert.[1999]

Dominios en Internet

Mapping the Internet: Domains Names & Nameservers
Ogle Earth

Country Codes of the World maps 245 top-level domain country codes encompassing all United Nations countries as well as numerous islands and territories. (At the end of every URL and email address is a top-level domain. Although .com is the world’s most popular top-level domain, it is far from alone. There are more than 260 top-level domains in use around the world, most of which are country code top-level domains.)

Each two-digit code is aligned over the country it represents and is color coded with the legend below for quick and easy reference.

Each two-digit code is sized relative to the population of the country or territory, with the exception of China and India, which were restrained by 30% to fit the layout. At the other end of the spectrum, the smallest type size used reflects those countries with fewer than 10 million residents.
