Bluetooth uses protocols that make it easy to discover devices that are nearby, and to set up a connection between these devices. Bluetooth devices can advertise all the services they offer. Using services becomes easier; a lot of the setup related to security, networking or permissions is automatic.
WLANs are more like traditional LANs. More configuration is needed to set up the network, and to make resources accessible by other devices in the network. WLAN devices also consume more power than Bluetooth ones.
Sometimes WLANs are called wireless Ethernet. WLAN needs more resources to be set up, but it also offers faster transfer speeds. The security is also better than that offered by Bluetooth.
Noraduz
Noraduz (or Noratus) is a site in the region of Gegharkunik in Armenia near Lake Sevan. It was formed a church dedicated to Sainte-mère-de-Dieu (built in the ninth century), and an exceptional site of medieval tombs. The tombstones are called Khachkars. Noraduz is the most important place for Khachkars in Armenia.
1921 New York Yankees season
The New York Yankees during 1921 (the 1921 season) was the 19th season for the Yankees in New York, and overall it was their 21st season. The season ended in the team having a record (the number of wins and losses) of 98-55 (98 wins, 55 losses). This was the first pennant won in Yankees history. They won the American League game pennant, replacing the previous winners, Cleveland Indians. The manager of their team was Miller Huggins. The Yankees home games were played on the Polo Grounds.
Hominidae
The hominids are members of the biological family Hominidae (the great apes). This includes humans, chimpanzees, gorillas and orangutans. "Great ape" is a common name rather than a taxonomic label and there are differences in usage. Sometimes it seems to exclude humans ("humans and the great apes"); at other times it includes them ("humans and non-human great apes"). "Homo sapiens" is definitely a hominid, as judged by all modern reference works.
Hominids range in weight from 48 kg to 270 kg. Males are larger than females. Hominids are primates with no tails, robust bodies and well-developed forearms. Their thumbs (and big toes, except in humans) oppose the fingers, and form a grip. All digits have flattened nails.
At present, the Hominidae includes four genera and five species. Its nonhuman members are restricted to rain forests in equatorial Africa, Sumatra and Borneo. However, if fossil hominids are included, then all the Australopithecines and the genus "Homo" are included. Hominid fossils date from the Miocene. They are known from Asia, and from Europe. Neanderthals were in Europe and western Asia for a long time (at least half a million years) before the emergence of our species. Asia had a huge version of the orangutan: "Gigantopithecus".
Details of the classification are not universally agreed at present.
A more recent classification underlines the Australopithecines and humans as distinct from the rainforest apes. It has the support of two major reference works.

Acropolis of Athens
The Acropolis of Athens is the most famous acropolis. It is a large hill in the center of Athens, on which the Parthenon and other Greek buildings were built. It is often known as "The" Acropolis.
Toki Pona
Toki Pona (in Toki Pona it means "good language" or "simple language") is a constructed (made-up) language. Sonja Lang (in past time "Sonja Elen Kisa"), a Canadian translator and linguist, made the language. It is based on simple ideas that are known to all cultures. It is not created to be an international auxiliary language (a language for communication between people speaking different languages). It is meant to test ideas about minimalism and pidgins. It is influenced by Taoist ideas. It has only 120 root words, although there is over 50,000 different possible combinations. Toki Pona relies very heavily on expressing ideas by using root words together. For example, "jan pona" means "friend" in Toki Pona (literally it means: "good person").
Normally Toki Pona uses the Latin alphabet, but many Toki Pona speakers create other systems of writing for this language. There are some attempts to create a writing system based on pictograms, but they have not been very successful.
Lord's Prayer (translated by Pije/Jopi):
mama pi mi mute o, sina lon sewi kon.

Amen.
Canadian Hurricane Centre
The Canadian Hurricane Centre (CHC) is a Canadian agency that is responsible for monitoring and tracking tropical cyclones that come near or affects Canadian territory. The agency warns people about on-coming tropical cyclones and makes hurricane advisories when needed. Its headquarters are in Dartmouth, Nova Scotia.
CHC usually works together with its United States counterpart, the National Hurricane Center in Miami, to coordinate the tracks and positions of all storms that show a possible threat to Canada.
While Atlantic hurricanes are normally uncommon in Canada, they do approach or strike from time to time. Among recent events are Hurricane Bob, which struck New Brunswick, in 1991, Hurricane Luis which struck Newfoundland in September 1995, Hurricane Hortense which struck Nova Scotia in September 1996, Hurricane Michael which struck Newfoundland in October 2000, and Hurricane Juan, which struck Nova Scotia in September 2003.
V-type asteroid
V-type asteroids or Vestoids are asteroids that are similar to 4 Vesta, by far the largest asteroid in this class (hence the name).
Vulcan (Star Trek)
Vulcans are a humanoid species in the fictional "Star Trek" universe who hail from the planet Vulcan, and are noted for their attempt to live by reason and logic with no interference from emotion. They were the first
extraterrestrial species encountered by Humans, and later became one of the founding members of the United Federation of Planets. Vulcans are featured in all six Star Trek series, four of which featured a Vulcan as a main character.
Keck Observatory
The W. M. Keck Observatory is a pair of two large, ground-based telescopes located at Mauna Kea, Hawaii. Sitting four km (more than two miles) above sea level, the paired telescopes are used to examine light from distant stars in great detail. The primary mirrors of each of the two telescopes are 10 meters (33 feet) across, making them slightly smaller than the Gran Telescopio Canarias primary mirrors.
However, all of the light collected by the Keck Observatory primary mirrors (75.76m2) is sent to the secondary mirror and the instruments, compared to GTC's primary mirror, which has an effective light-collection area of 73.4m2, or 25.4 square feet less than each of the Keck Observatory primary mirrors. Because of this fundamental difference in design, Keck Observatory's telescopes arguably remain the largest steerable, optical/infrared telescopes on Earth.

HED meteorite
The HED meteorites are a grouping of achondrite meteorite types, the:
These are all thought to have originated from the crust of the asteroid 4 Vesta, their differences being due to different geologic histories of the parent rock. Their crystallization ages have been determined to be between 4.43 and 4.55 billion years from radioisotope ratios.
Metamorphic rock
A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change).
The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change. The original rock may be sedimentary rock, igneous rock or another older metamorphic rock.
