Hydra may refer to:
Hydra was a chess machine, designed by a team with Dr. Christian "Chrilly" Donninger, Dr. Ulf Lorenz, GM Christopher Lutz and Muhammad Nasir Ali. Since 2006 the development team consisted only of Donninger and Lutz. Hydra was under the patronage of the PAL Group and Sheikh Tahnoon Bin Zayed Al Nahyan of Abu Dhabi. The goal of the Hydra Project was to dominate the computer chess world, and finally have an accepted victory over humans.
Hydra represented a potentially significant leap in the strength of computer chess. Design team member Lorenz estimates its FIDE equivalent playing strength to be over Elo 3000, and this is in line with its results against Michael Adams and Shredder 8, the former micro-computer chess champion.
Hydra began competing in 2002 and played its last game in June 2006. In June 2009, Christopher Lutz stated that "unfortunately the Hydra project is discontinued." The sponsors decided to end the project.
The Hydra team originally planned to have Hydra appear in four versions: Orthus, Chimera, Scylla and then the final Hydra version – the strongest of them all. The original version of Hydra evolved from an earlier design called Brutus and works in a similar fashion to Deep Blue, utilising large numbers of purpose-designed chips (in this case implemented as a field-programmable gate array or FPGA). In Hydra, there are multiple computers, each with its own FPGA acting as a chess coprocessor. These co-processors enabled Hydra to search enormous numbers of positions per second, making each processor more than ten times faster than an unaided computer.
Hydra is the sixth studio album by Dutch symphonic metal band Within Temptation. It was released on January 31, 2014 in Europe and on February 4, 2014 in North America. The album contains guest appearances by singer Howard Jones (ex-Killswitch Engage), rapper Xzibit, metal vocalist Tarja Turunen (ex-Nightwish) and alternative rock singer Dave Pirner (Soul Asylum). The first single, "Paradise (What About Us?)", was released on September 27, 2013, and featured Turunen as guest vocalist. The second single, "Dangerous", was released on December 20, in which Jones provided the male vocals.
This is the first album by Within Temptation to be recorded with three guitarists, with Stefan Helleblad making his Within Temptation studio debut on Hydra since his addition to the band shortly after the release of The Unforgiving in 2011. Hydra is also the first Within Temptation album to feature Robert Westerholt's growling techniques since the band's debut album, Enter.
Nitroplus Co., Ltd., stylized as nitro+, is a Japanese visual novel computer software company that has developed a number of visual novels, including eroge. They also have been collaborating with TYPE-MOON (another developer) to create the light novel series Fate/Zero. Their works usually have dark themes such as reanimation of the dead and murder. They also have a branch of the company called Nitro+Chiral, which focuses on Boys' Love visual novels. Writers aligned with the company, such as Gen Urobuchi, have also contributed to various manga, anime, novel, and television works.
Super Sonico is the mascot of Nitroplus' annual music festival event, "Nitro Super Sonico", since 2006. Nitroplus has held their music festival every year since 2000.
Nitro from Conexant (originally developed by Intersil) is a proprietary 802.11g performance enhancement technology introduced in 2003 as part of the PRISM chipset. The first implementation was designed to help compensate for the performance loss of higher-speed 802.11g devices when they share a wireless network with slower 802.11b devices.
Later implementations are marketed as Nitro MX Xtreme which adds proprietary frame-bursting, compression and point-to-point side session technology for a claimed 140 Mbit/s throughput transmission speed. The point-to-point side session technology, called DirectLink, creates a connection between clients or from a client to a media source, such as a media server, and avoids the access point. It does this while staying in 802.11 Infrastructure mode so the client can continue to utilize access point-based security and power-savings.
Nitro is one of several competing incompatible proprietary extension approaches that were developed to increase performance of 802.11g wireless devices, such as 125 High Speed Mode from Broadcom, Super G (or "108 Mbit/s" technology) from Atheros, and MIMO-based extensions from Airgo Networks.
Nitro is an top-down perspective arcade racer for the Amiga and Atari ST. It was developed and published in 1990 by Psygnosis.
This game contains no clear background or storyline, just white-knuckle video game racing. After choosing whether to play with one, two or three (via keyboard) players, the player(s) must select a car and buy accessories at the "pit stop" before proceeding to the race. Three vehicles are available; namely the racing car, sports car, and turbo buggy. Accessories include nitros, high speed, acceleration, traction, fix damage, a change of car, as well as fuel which is imperative to the racing campaign.
The game consists of 32 levels, but the game ends when the fuel is depleted. To prevent this, the player must finish in a high place on most races, which rewards the player with up to 600 gasoline units. In addition, power-ups float around in the levels as well as being placed on the track, but these may be picked up by any of the four cars.
