Radiohead

Jovan Stosic April 21, 2020

Radiohead are an English rock band formed in Abingdon, Oxfordshire in 1985. The band consists of Thom Yorke (vocals, guitar, piano, keyboards), brothers Jonny Greenwood (lead guitar, keyboards, other instruments) and Colin Greenwood (bass), Ed O’Brien (guitar, backing vocals) and Philip Selway (drums, percussion). They have worked with producer Nigel Godrich and cover artist Stanley Donwood since 1994.

After signing to EMI in 1991, Radiohead released their debut single “Creep” in 1992. It became a worldwide hit after the release of their debut album, Pablo Honey (1993). Their popularity and critical standing rose in the United Kingdom with the release of their second album, The Bends (1995). Radiohead’s third album, OK Computer (1997), brought them international fame; noted for its complex production and themes of modern alienation, it is often acclaimed as a landmark record of the 1990s and one of the best albums in popular music. Kid A (2000) and Amnesiac (2001), recorded simultaneously, marked a dramatic change in style, incorporating influences from experimental electronic music, 20th-century classical music, krautrock, and jazz. Kid A divided listeners but was named the best album of the decade by Rolling Stone, Pitchfork and The Times.

Hail to the Thief (2003) mixed rock and electronic music with lyrics inspired by the War on Terror, and was Radiohead’s final album for EMI. Their subsequent releases have pioneered alternative release platforms such as pay-what-you-want and BitTorrent; Radiohead self-released their seventh album, In Rainbows (2007), as a download for which customers could set their own price, to critical and chart success. Their eighth album, The King of Limbs (2011), an exploration of rhythm, was developed using extensive looping and sampling. A Moon Shaped Pool (2016) prominently featured Jonny Greenwood’s orchestral arrangements. Jonny Greenwood, Yorke, Selway, and O’Brien have released solo works.

Radiohead had sold more than 30 million albums worldwide by 2011. Their work places highly in both listener polls and critics’ lists of the best music of the 1990s, 2000s, and 2010s. They were inducted into the Rock and Roll Hall of Fame in 2019.

MIPS architecture

Jovan Stosic April 20, 2020

MIPS (Microprocessor without Interlocked Pipelined Stages) is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by MIPS Computer Systems, now MIPS Technologies, based in the United States.

There are multiple versions of MIPS: including MIPS I, II, III, IV, and V; as well as five releases of MIPS32/64 (for 32- and 64-bit implementations, respectively). The early MIPS architectures were 32-bit only; 64-bit versions were developed later. As of April 2017, the current version of MIPS is MIPS32/64 Release 6. MIPS32/64 primarily differs from MIPS I–V by defining the privileged kernel mode System Control Coprocessor in addition to the user mode architecture.

The MIPS architecture has several optional extensions. MIPS-3D which is a simple set of floating-point SIMD instructions dedicated to common 3D tasks, MDMX (MaDMaX) which is a more extensive integer SIMD instruction set using the 64-bit floating-point registers, MIPS16e which adds compression to the instruction stream to make programs take up less room, and MIPS MT, which adds multithreading capability.

Computer architecture courses in universities and technical schools often study the MIPS architecture. The architecture greatly influenced later RISC architectures such as Alpha.

Aqua-Lung

Jovan Stosic April 18, 2020

Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus (or “scuba”) to reach worldwide popularity and commercial success. Aqua-Lung was the brand of air regulator, which could be attached to gas tanks. This class of regulator is now commonly referred to as a diving regulator, or demand valve. The Aqua-Lung was invented in France during the winter of 1942–1943 by two Frenchmen: the engineer Émile Gagnan and the Naval Lieutenant (French: “lieutenant de vaisseau”) Jacques Cousteau. It allowed Cousteau and Gagnan to film and explore more easily underwater.
