Tierra (computer simulation)

Tierra is a computer simulation developed by ecologist Thomas S. Ray in the early 1990s in which computer programs compete for time (central processing unit (CPU) time) and space (access to main memory). In this context, the computer programs in Tierra are considered to be evolvable and can mutate, self-replicate and recombine. Tierra's virtual machine is written in C. It operates on a custom instruction set designed to facilitate code changes and reordering, including features such as jump to template (as opposed to the relative or absolute jumps common to most instruction sets).

Simulations

The basic Tierra model has been used to experimentally explore in silico the basic processes of evolutionary and ecological dynamics. Processes such as the dynamics of punctuated equilibrium, host-parasite co-evolution and density-dependent natural selection are amenable to investigation within the Tierra framework. A notable difference between Tierra and more conventional models of evolutionary computation, such as genetic algorithms, is that there is no explicit, or exogenous fitness function built into the model. Often in such models there is the notion of a function being "optimized"; in the case of Tierra, the fitness function is endogenous: there is simply survival and death.

Tierra (band)

Tierra is a Latin R&B band, originally from Los Angeles, California, that was first established in the 1970s by former El Chicano members Steve Salas (vocals) and his brother Rudy Salas (guitar). The other original members were Bobby Navarrete (reeds), Joey Guerra (keyboards), Steve Falomir (bass guitar), and Philip Madayag (drums) and Andre Baeza (percussion). Their biggest hit was the 1980 remake of The Intruders' 1967 hit "Together", written by Gamble & Huff, which reached #18 on the Billboard Hot 100, and #9 on the US Billboard R&B chart.

Background

Tierra has the distinction of being the first Latino band to have four songs on the national chart with two of them in the Top 100 at the same time.

Around 1973, Rudy and Steve Salas formed Tierra and their self-titled debut album was recorded. By the mid-1970s the band consisted of the Salas brothers, Rudy Villa on reeds, Kenny Romain on drums and latin-percussion, Conrad Lazano on bass, Aaron Ballesteros on drums and vocals, Alfred Rubaclava on bass and Leon Bisquera on keyboards. Around that time they recorded the album Stranded for the Salsoul records label.

Lego

Lego (/ˈlɛɡoʊ/) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colorful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways, to construct objects such as vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.

The Lego Group began manufacturing the interlocking toy bricks in 1949. Since then a global Lego subculture has developed. Supporting movies, games, competitions, and six Legoland amusement parks have been developed under the brand. As of July 2015, 600 billion Lego parts had been produced.

In February 2015, Lego replaced Ferrari as Brand Finance's "world's most powerful brand".

History

The Lego Group began in the workshop of Ole Kirk Christiansen (1891–1958), a carpenter from Billund, Denmark, who began making wooden toys in 1932. In 1934, his company came to be called "Lego", derived from the Danish phrase leg godt, which means "play well". In 1947, Lego expanded to begin producing plastic toys. In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based in part on the Kiddicraft Self-Locking Bricks, which were patented in the United Kingdom in 1939 and released in 1947. Lego modified the design of the Kiddicraft brick after examining a sample that they received from the supplier of an injection-molding machine that Lego purchased. The bricks, originally manufactured from cellulose acetate, were a development of the traditional stackable wooden blocks of the time.

List of Lego video games

Since 1997, 57 video games based on the Lego construction system have been released. After the first game, Lego Island, developed and published by Mindscape, The Lego Group opened publishing subsidiary Lego Media to further release Lego-themed games based on their production line. In 2005, Lego Videogames licensed Giant Interactive Entertainment to publish from that point on, which is was then bought by Traveller's Tales and became TT Games Publishing. TT Games Publishing has since licensed several properties for use in their video games, including Star Wars, Batman and Rock Band, among others. In 2007, Traveller's Tales bought developer Embryonic Studios, reforming it into TT Fusion. Traveller's Tales and subsidiaries were bought-out by Warner Bros. Interactive Entertainment on November 8, 2007, who are now in charge of the publishing.
