Arusha is a town in northern Tanzania. Its airport code is ARK. I, Will Partain (project founder), grew up there. I like it; it's a cool name. Had I ever had reason (e.g. talent) to start a band, I would have called it "Arusha".

Some facts about Arusha:

Arusha is the nearest town to all of the northern Tanzanian game parks (Manyara, Ngorongoro, Serengeti, Tarangire, etc.). Arusha is bulging at the seams with "tour operators".
Arusha is at the foot of Mount Meru [14,979ft/4,566m], the fifth highest mountain in Africa. Regrettably, it is less than 50 miles/80 km. from the first highest (Kilimanjaro), so it tends to be overlooked.
Meru is allegedly an active volcano and last erupted in 1910. I wish somebody had bothered to tell me this when I was a kid (and/or the two times I climbed it :-).
Arusha National Park is a small-but-perfectly-formed game park that takes in the east side of Mt Meru, from up in its crater, down to the Momela lakes and Ngurdoto crater below.
Arusha town itself is 5,053ft/1,540m above sea level, and is ever-so-approximately half way on the Cape-to-Cairo route through Africa. Weather: fantastic!
The Arusa people (also: Arusha) are among those who live in the Arusha area (surprise). The Arusa are an-offshoot/cousins-of the Maasai, with their language being a dialect of the Maa language. (More hard data about the Arusa most welcome!)
In the late '60s, Arusha was due to become the headquarters of the East African Community (EAC), a European-Community-like grouping of Kenya, Tanzania, and Uganda. It never quite happened, though, because Idi Amin came to power in Uganda, and Tanzania's president, the late Julius Nyerere, just couldn't do business with him. (In fact, Nyerere sent in the Tanzanian troops that overthrew Amin in 1979.)
Arusha got a set of buildings that were to be the EAC headquarters, which turned into an "international conference centre".
Those same facilities are part of the reason Arusha was chosen as the place for the United Nations International Criminal Tribunal for Rwanda [UN-ICTR], following the genocide there in 1994.
The first ever international court verdict on genocide was given in Arusha on 4th September, 1998.
The "Arusha Declaration", by President Nyerere in 1967, was a milestone in the development of "African socialism", which has had a central place in recent Tanzanian history (for better or worse).
The Declaration has had a wide influence beyond Tanzania. For example, there is an "Arusha Centre" in Calgary, Alberta, Canada, dedicated to its principles.
The cheesy 1962 movie "Hatari!" (comedy, starring John Wayne) was filmed in Arusha and environs (including the Momela lodge).
Arusha hasn't been at the forefront of computerisation. I believe that the Tanganyika Farmers Association had an ICL ME29 in the mid-1980s, which suggests that they had had other ICL 1900 series computers for a while before that.
Pre-PCs, I reckon you could count Arusha's computers on the fingers of one hand. Send in corrections/details, please!
