The Hydra II is the latest generation of HQ's most popular trainer kite. HQ has created a kite with improved flying performance and responsiveness, providing more power through the turns. Welcome to the black mesa transit system. The Closed Cell Technology allows reliable water relaunches and makes the Hydra II the most versatile trainer kite for lessons on land or in the water. The FreeStyle is closer to the Ride. My Tag Cannon is at least 5-7 boards more than my Ride was « Last Edit: May 14, 2018, 03:07:34 PM by SVstar34 ».
Hydra species[1][2]
Hydra,
was a chess playing entity based on a Myrinetcomputer cluster consisting of FPGAs and x86 PCs.Hydra was the continuous development of the ChessBase funded FPGA project called Brutus by Chrilly Donninger et al. now under the patronage of the Pal Group of Companies[3] and SheikhTahnoun Bin Zayed Al Nahyan[4][5][6] of Abu Dhabi, United Arab Emirates.

Hydra had its tournament debut at the IPCCC 2004 winning clearly with 6½/7 ahead of Fritz and Shredder. Soon later, at the ICT 2004, Hydra came in behind Shredder,but taking revanche in August 2004, winning a match with 6½-2½. Also the IPCCC 2005 was dominated with 8/9, a half point ahead of Shredder. Hydra also achieved strong results versus humans, playing two times the Man vs Machine Team Championship, and in 2005 versusMichael Adams winning decisively with 6½-½.The chess monster further played freestyle matches along with its sponsor, chess lover and chess player under the pseudonym Zorchamp[7], and was active on the Playchess server - its last game in June 2006 [8]. In June 2009, Hydra book author Christopher Lutz stated that 'unfortunately the Hydra project is discontinued.' The sponsors decided to end the project [9].
Hydra [10] ran on a Myrinet interconnected Linuxcluster of four (later eight) dual PC server nodes able to handle two PCI buses, which are conneced to a FPGA card each, simultaneously. The distributed search algorithm ran on the x86 nodes as MPIprocesses, where the last three plies of an n-ply search including quiescence and all evaluations are delegated to the FPGA card, typically 100.000 times per second and processor. For further information see the description of Brutus.

2008
The Hydra team, led by Abdul Mateen Khan, was working on two new chess projects: Cryptic and Shark, as in 2008 mentioned on the now defunct Hydra site, and from May 2008 until December 2009 on Wikipedia [11][12]:
- Cryptic runs on modern high speed multi-processor CPU. It is programmed in mixed C and Assembly Language. It is aimed to be the world's top single machine Chess Engine.
- Shark is network based deep search meta engine. It is based on unique idea by which it reaches to depth of 25+ easily with the help of only 6 CPUs in less than a minute. Currently a dual core CPU takes more than an hour to reach to this depth.

Another program by Donninger and Alex Kure was also named Hydra and played the 15th World Microcomputer Chess Championship in Paris 1997.

- Abstract
- With the help of the FPGA technology, the boarder between hard- and software has vanished. It is now possible to develop complex designs and fine grained parallel applications without the long-lasting chip design cycles. Additionally, it has become easier to write coarse grained parallel applications with the help of message passing libraries like MPI. The chess program Hydra is a high level hardware-software co-design application which profits from both worlds. We describe the design philosophy, general architecture and performance of Hydra. The time critical part of the search tree, near the leaves, is explored with the help of fine grain parallelism of FPGA cards. For nodes near the root, the search algorithm runs distributed on a cluster of conventional processors. A nice detail is that the FPGA cards allow the implementation of sophisticated chess knowledge without decreasing the computational speed.

Pain relief, tension reduction and relaxation were reported to have persisted for up to a day or longer in more than 70% of the massage group participants.
Employees who received 20-minutes of seated massage twice weekly for 8 weeks showed decreased anxiety levels, fewer sleep disturbances, and improved blood pressure and heart rate.
The results indicated a consistent and significant trend of increased activity of both T and B lymphocytes and levels of serum IgG for both subjects during the B phases compared to the A phases.
