Habbo

Habbo (previously known as Habbo Hotel) is a social networking service and online community aimed at teenagers. The website is owned and operated by Sulake, a Finnish corporation. The service began in 2000 and has expanded to include nine online communities (or "hotels"), with users in over 150 countries. As of August 2012, over 273 million avatars have been registered with an average 5 million unique visitors monthly. 90% of Habbo's users are between the age of 13 and 18.

The service allows users to create their own Habbo character and design hotel rooms, meet new friends, chat with other players, organize parties, look after virtual pets, create and play games and complete quests.

History

Habbo stemmed from a 1999 hobby project by creative designer Sampo Karjalainen and technologist Aapo Kyrölä entitled Mobiles Disco, for a Finnish band. It was a virtual chat room running on Aapo's Fuse technology. After having been contracted to design a virtual game and chat called Lumisota (Snow Wars) for a Finnish internet service provider, they were contracted for another project. They developed Hotelli Kultakala (eng. Hotel Goldfish) with a small team of developers. It launched in August 2000 on the ISP's web portal.

All rights reserved

"All rights reserved" is a phrase that originated in copyright law as a formal requirement for copyright notice. It indicates that the copyright holder reserves, or holds for their own use, all the rights provided by copyright law under one specific copyright treaty.

Origins

The phrase appears to have originated as a result of the Buenos Aires Convention of 1910. Article 3 of the Convention granted copyright in all signatory countries to a work registered in any signatory country, as long as a statement "that indicates the reservation of the property right" (emphasis added) appeared in the work. The phrase "all rights reserved" was not specified in the text, but met this requirement.

Other international copyright treaties did not require this formality. For example, the Universal Copyright Convention (UCC), adopted in 1952, adopted the © symbol as an indicator of protection. (The symbol had been introduced in the US by a 1954 amendment to the Copyright Act of 1909.) The Berne Convention rejected formalities altogether in Article 4 of the 1908 revision, so authors seeking to protect their works in countries that had signed on to the Berne Convention were also not required to use the "all rights reserved" formulation. However, because not all Buenos Aires signatories were members of Berne or the UCC, and in particular the United States did not join UCC until 1955, a publisher in a Buenos Aires signatory seeking to protect a work in the greatest number of countries between 1910 and 1952 would have used both the phrase "all rights reserved" and the copyright symbol.

Aviation

Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word "aviation" was coined by French writer and former naval officer Gabriel La Landelle in 1873, from the verb "avier" (synonymous flying), itself derived from the Latin word "avis" ("bird") and the suffix "-ation".

History

Early beginnings

There are early legends of human flight such as the story of Icarus in Greek myth and Jamshid in Persian myth, and later, somewhat more credible claims of short-distance human flights appear, such as the flying automaton of Archytas of Tarentum (428–347 BC), the winged flights of Abbas Ibn Firnas (810–887), Eilmer of Malmesbury (11th century), and the hot-air Passarola of Bartholomeu Lourenço de Gusmão (1685–1724).

Lighter than air

The modern age of aviation began with the first untethered human lighter-than-air flight on November 21, 1783 of a hot air balloon designed by the Montgolfier brothers. The practicality of balloons was limited because they could only travel downwind. It was immediately recognized that a steerable, or dirigible, balloon was required. Jean-Pierre Blanchard flew the first human-powered dirigible in 1784 and crossed the English Channel in one in 1785.

Diamond Aircraft Industries

Diamond Aircraft Industries is an Austrian-based manufacturer of general aviation aircraft and motor gliders, which also has a large manufacturing facility in London, Ontario, Canada.

The company produces a range of light aircraft and is engaged in the development of a single-engined jet aircraft, the Diamond D-Jet.

History

1980s

The company was founded as Hoffmann Flugzeugbau by Wolf Hoffmann in Friesach, Austria, in 1981, to produce the H36 all-composite motor glider. Becoming Hoffman Aircraft Limited in 1985, and a subsidiary of Simmering-Graz-Pauker AG, the company moved its headquarters to Vienna, Austria. In 1987 the company moved its factory to Wiener Neustadt, Austria. In 1991 the parent company was renamed HOAC AG and purchased by the Dries Family. In the same year, the company started development of the HK36R a Rotax 912 powered motorglider, which was the precursor to the DV20 Katana, the company's first production general aviation aircraft.

1990s

In 1992, to supply the North American market more directly, the company opened a second manufacturing facility in London, Ontario, Canada. The Canadian operation used the name Dimona Aircraft until it was changed to Diamond Aircraft in 1996, while the parent company remained HOAC.
