The GNU General Public License (GPL) is a computer software copyleft license. This license lets the user of the software use a program in many of the same ways as if it were public domain. They can use it, change it, and copy it. They can also sell or give away copies of the program with or without any changes they made to it. The license lets them do this as long as they agree to follow the terms of the license. The GPL was created by Richard Stallman. The current version is version 3, created in 2007, although some software still uses version 2, created in 1991.
There are two main terms to the license. Both apply to giving the program away or selling it.
If the user does not agree to follow the GPL, they can still use the software under copyright laws. They can use it and make copies or changes to it for themselves, but they cannot give it away or sell it. They also can not change the license.
Triangle (disambiguation)
In geometry, a triangle is the flat shape formed by joining three points (not in a straight line) with straight line segments. A triangle is a three sided polygon.
In music, a triangle is a musical instrument that is made from a metal tube. It is in the shape of a triangle. It is open at one corner, and when it is hit with a metal stick, it makes a sound.
Square
A square is a shape with four equal sides and four corners that are all right angles (90 degrees). The diagonals of a square also cross at right angles. The angle between any diagonal and a side of a square is 45 degrees. A square has rotational symmetry of four. It has four lines of regular symmetry. A square with vertices "A", "B", "C" and "D" can be written as formula_1.
A square is a type of rectangle with all sides of equal length. However, while a square is a type of rectangle and rhombus, the opposite does not need to be true.
A square is also the 2-dimensional analogue of a cube.
If the length of side "a" is known, then we have that:
If the length of diagonal "d" is known, then we have that:
Computer hardware
Computer hardware or hardware means the physical parts that make up a computer.
Some examples are:
Hardware needs software to tell it what to do. Without software, the hardware cannot be used.
Meat
Meat is animal tissue used as food. Most often is used to describe skeletal muscle and fat that is found with it. Types of meat include beef and veal from cattle, pork, ham and bacon from pigs, mutton from sheep, "venison" from deer, fish, insects, and poultry from chickens, ducks and turkeys. The word meat is also used for sausages and for non-muscle organs which are used for food, for example liver, brain, and kidneys.
In the meat processing industry, (in some countries) the word "meat" is to mean only the flesh of mammalian species such as pigs, cattle, etc. but does not include fish, insects and poultry.
Animals such as members of the cat family that mainly eat animals are called carnivores.
Meat is an important part of the diet of many people because it has protein. Protein helps the growth and healing of a body and gives energy. Meat is a "high-protein" food, but costs more than other foods like bread and vegetables. Meat is also a source of B vitamins. People who cannot afford meat, or who do not like to eat it need to find other ways to get enough protein in their diet. Beans and certain nuts are also high in protein. People that choose not to eat meat are called vegetarians, and those who do not eat any animal products are known as vegans.
Red meat is darker-coloured meat, different from white meat such as chicken or fish. Most raw meat can make people sick or even cause death.
Due to religious dietary law, Halal (حلال) meaning permissible in Arabic is used as a visual marker for Muslims on shops and on products.
Anders Celsius
Anders Celsius (27 November 1701 – 25 April 1744) was a Swedish astronomer. Celsius was born in Uppsala in Sweden. Much of his work was in what was later called Geodesy.
He is more famous for developing the Celsius temperature scale when he worked on meteorology (a science about weather conditions). It later became an the international standard. One of his good friends Daniel Gabriel Fahrenheit invented the Fahrenheit scale for the thermometer.
Tuvalu
Tuvalu is a small island country in the Pacific Ocean. In the past, it was the Ellice Islands. It was part of Gilbert and Ellice Islands. It is a monarchy.
Tuvalu is getting smaller. If the sea level keeps rising at the same rate, this country will be covered by water in about 50 years.
The most important language spoken in Tuvalu is Tuvaluan, although Nuian is spoken on the island of Nui.
The United States and Tuvalu signed a treaty of friendship in 1979, when the US gave up their claim to Tuvalu for the islands of Funafuti, Nukefetau, Nukulaelae, and Nurakita.
Tuvalu is made up of 9 islands:
Internet Domain name .tv
Following Tuvalu being allocated two-letter top-level Internet domain suffix, .tv, the Government of Tuvalu worked with the International Telecommunications Union and established a process to select a management partner for the domain suffix.
On 6 August 1998 a licensing agreement was signed with Information.CA of Toronto under which it agreed to pay an up-front payment of US$50 million for exclusive marketing rights to Tuvalu's domain until 2048, with the country manager/delegee of the Government of Tuvalu for the .tv extension being The .tv Corporation International, which was established in 1998. Subsequent negotiations with Information.CA followed from the delays in payment of US$50 million. Idealab, a Californian company, became involved in 1999 and assumed the $50 million obligation to be paid over 10 years. With the first $1 million payment, Tuvalu was finally able to afford to join the United Nations. Lou Kerner became the first employee of .tv when he joined as CEO in January 2000. .tv grew to over 100 employees, with offices in Los Angeles, London, and Hong Kong, before being acquired in a nine figure transaction in December, 2001.
Tuvalu has four reef islands and five true atolls. The atolls have only 26 km of land. Tuvalu is the fourth smallest country in the world. The land is very low lying and the coral atolls are narrow. Funafuti is the largest atoll of the islands and atolls. It has many islets around a central lagoon. This is about 25.1 kilometres (15.6 mi) (N–S) by 18.4 kilometres (11.4 mi) (W-E), centered on 179°7’E and 8°30’S. A
The highest height is above sea level, which gives Tuvalu the second-lowest highest elevation of any country (after the Maldives). Because of this, the islands that make up Tuvalu are threatened by any sea level rise. If this happens, the people will have to go to New Zealand, Niue or the Fijian island of Kioa. Tuvalu is also affected by what is known as a king tide, which can raise the sea level higher than a normal high tide.
Java
Java () is one of the islands of Indonesia.
The area is 132,000 square km. It is the world's 13th largest island. Around 140 million people live there, which is half the people in Indonesia and more than on any other island in the world. Most of them speak the Javanese language and many also speak other languages.
The Java Sea is to the north, the Indian Ocean south. The capital city of Indonesia, Jakarta, is in Java.
Most of Java has a tropical monsoon climate (Am in the Koeppen climate classification). The northern coast of the island is low-lying. The soil is fertile, because the island was made by volcanoes. It is an important area for growing crops in Indonesia.
