Tor (anonymity network)

Tor is free software for enabling anonymous communication. The name is an acronym derived from the original software project name The Onion Router, however the correct spelling is "Tor", capitalizing only the first letter. Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult for Internet activity to be traced back to the user: this includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's use is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities from being monitored.

Onion routing is implemented by encryption in the application layer of a communication protocol stack, nested like the layers of an onion. Tor encrypts the data, including the destination IP address, multiple times and sends it through a virtual circuit comprising successive, randomly selected Tor relays. Each relay decrypts a layer of encryption to reveal only the next relay in the circuit in order to pass the remaining encrypted data on to it. The final relay decrypts the innermost layer of encryption and sends the original data to its destination without revealing, or even knowing, the source IP address. Because the routing of the communication is partly concealed at every hop in the Tor circuit, this method eliminates any single point at which the communicating peers can be determined through network surveillance that relies upon knowing its source and destination.

ARM (novella)

ARM is a science fiction novella by American author Larry Niven. Set in the Known Space cycle, it is the third of five Gil Hamilton detective stories.

Hamilton is called to the scene of a murder. The victim is Dr. Raymond Sinclair, a brilliant scientist who has invented a mysterious device that creates a bubble of accelerated time. The murder scene is a locked apartment at the top of a high-rise, where the prime suspect is a beautiful young woman whom Gil refuses to believe is the killer.

One of the themes running throughout the story, and in fact a vital element in the solution of the mystery, is the loss of an arm. Gil himself lost an arm and had a new one grafted on, using parts from an organ bank which is supplied by the bodies of criminals and "corpsicles", people who underwent cryogenic suspension. At the scene of the crime, a beautiful young woman is discovered unconscious in an "autodoc" (a device for fixing minor injuries or preserving life until help arrives) recovering from the loss of one of her arms. Another character in the story also lost an arm previously, but regards grafts as immoral and wears an advanced prosthetic arm instead. The "accelerated time bubble" has the effect of amputating the arm of anyone who reaches into it, since the arm's metabolism speeds up to the point where the rest of the body cannot supply it with blood.

2ARM

2ARM FM is a community radio station broadcasting to Armidale, NSW having had its Permanent Community Broadcasting Licence reinstated after operating on a Temporary Community Broadcasting Licence (TCBL). The station has been broadcasting for over 31 years to Armidale,Walcha, Uralla, Guyra and all areas in between. It is volunteer based, and is a member of the Community Broadcasting Association of Australia (CBAA). It became an Incorporated Association in June, 2009.

History

The history of 2ARM is closely linked with that of 2UNE, and in fact with the beginning of the community broadcasting sector of Australia.

Professor Neville Fletcher, a lecturer at the University of New England at the time, presented the idea of a campus radio station to the students, and this led to letters to the Postmaster-General requesting a licence. The station was established through 1968-69, and utilised a "closed loop" system. Basically AM radio induction within buildings of the university.

The system allowed the broadcasts to be heard only inside the residential colleges at the University.

Software (novel)

Software is a 1982 cyberpunk science fiction novel written by Rudy Rucker. It won the first Philip K. Dick Award in 1983. The novel is the first book in Rucker's Ware Tetralogy, and was followed by a sequel, Wetware, in 1988.

Plot summary

Software introduces Cobb Anderson as a retired computer scientist who was once tried for treason for figuring out how to give robots artificial intelligence and free will, creating the race of boppers. By 2020, they have created a complex society on the Moon, where the boppers developed because they depend on super-cooled superconducting circuits. In that year, Anderson is a pheezer — a freaky geezer, Rucker's depiction of elderly Baby Boomers — living in poverty in Florida and terrified because he lacks the money to buy a new artificial heart to replace his failing, secondhand one.

As the story begins, Anderson is approached by a robot duplicate of himself who invites him to the Moon to be given immortality. Meanwhile, the series' other main character, Sta-Hi Mooney the 1st — born Stanley Hilary Mooney Jr. — a 25-year-old cab driver and "brainsurfer", is kidnapped by a gang of serial killers known as the Little Kidders who almost eat his brain. When Anderson and Mooney travel to the Moon together at the boppers' expense, they find that these events are closely related: the "immortality" given to Anderson turns out to be having his mind transferred into software via the same brain-destroying technique used by the Little Kidders.

Software (album)

Software is Grace Slick's 1984 album released by RCA Records. This album was recorded after she had re-joined Jefferson Starship. After working on this album, Peter Wolf would go on to contribute to Jefferson Starship's 1984 album, Nuclear Furniture. A music video was made for the single "All the Machines". "Software" is Grace Slick's fourth and final solo album.

Software has been described as Slick's attempt to assimilate with the techno-pop artists of the period. Guitar use is largely replaced by synthesizers and electric drums. Slick's trademark wailing vocals and improvising is replaced by more short short, precise bursts. The album failed to chart.

Personnel

Software (band)

Software was a German electronic duo active between 1984 and 2000, comprising Peter Mergener (born 1951) and Michael Weisser (born 1948). Formerly the duo used the name Mergener&Weisser.

History

The group released their records under the IC (Innovative Communication) label, which also released a number of other electronic musicians, including Klaus Schulze and the Neue Deutsche Welle group Ideal.

From 1990 to 1992 Weisser produced, during a temporary break with Mergener, four albums under the Software name with a different group composition: Fragrance with Klaus Schulze and Georg Stettner (born 1970), and Modesty-Blaze I / II and Cave with Billy Byte (Stephan Töteberg).

After the dissolution of Software in 1999, the two musicians went their separate ways: Peter Mergener continues to compose and play electronic music, while Michael Weisser first founded the group G.E.N.E. (Grooving Electronic Natural Environments), and is currently, among other things, active as a media artist.
