The 404 or Not Found error message is an HTTP standard response code indicating that the client was able to communicate with a given server, but the server could not find what was requested.
The web site hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a broken or dead link; hence the 404 error is one of the most recognizable errors encountered on the World Wide Web.
When communicating via HTTP, a server is required to respond to a request, such as a web browser request for a web page, with a numeric response code and an optional, mandatory, or disallowed (based upon the status code) message. In the code 404, the first digit indicates a client error, such as a mistyped Uniform Resource Locator (URL). The following two digits indicate the specific error encountered. HTTP's use of three-digit codes is similar to the use of such codes in earlier protocols such as FTP and NNTP.
At the HTTP level, a 404 response code is followed by a human-readable "reason phrase". The HTTP specification suggests the phrase "Not Found" and many web servers by default issue an HTML page that includes both the 404 code and the "Not Found" phrase.

Riders sit in seats arranged in a circle facing inwards, there are eight gondolas with four seats on each. After the over-the-shoulder restraints have been lowered and checked, the platform lowers. The seats then begin to rotate, and after approximately one rotation the ride begins to swing. The ride swings back and forth, swinging up to a maximum height of 20 metres and angle of 120 degrees at 15rpm. After several full height swings, the ride then begins to slow before coming to a halt, the platform is then raised and riders fast track and single rider questions operate.
Vortex is a high-fidelity, realtime physics engine developed by CM Labs Simulations that simulates rigid body dynamics, collision detection, contact determination, and dynamic reactions. Vortex adds accurate physical motion and interactions to objects in visual-simulation applications for operator training, mission planning, product concept validation, vehicle and robotics testing, haptics devices, immersive and virtual reality (VR) environments.
The Vortex C++ SDK has several modules that simulate physics-based particles, sensors, floating bodies, cable systems, grasping, and wheeled and tracked vehicles. Developers integrate their projects into 3D visualization frameworks such as OpenSceneGraph (OSG) and Vega Prime, and deploy them in environments that contain software-in-the-loop (SIL), MATLAB, hardware-in-the-loop (HIL), and motion platform components.
Vortex is developed by CM Labs Simulations Inc., a private company established in Montreal in 2001. CM Labs was created when the management of MathEngine Canada Inc. purchased a portion of the business from MathEngine PLC, the parent company in the UK. MathEngine Canada Inc. was originally the research and development team responsible for creating the Karma physics simulation engine for computer games.

Flood is the third studio album by Brooklyn-based alternative rock duo They Might Be Giants, released in January 1990. Flood was the duo's first album on the major label Elektra Records. It generated three singles: "Birdhouse in Your Soul", "Istanbul (Not Constantinople)", and the domestic promotional track "Twisting". The album is generally considered to be the band's definitive release, as it is their best-selling and most recognizable album. Despite minimal stylistic and instrumental differences from previous releases, Flood is distinguished by contributions from seasoned producers Clive Langer and Alan Winstanley. John Linnell and John Flansburgh also took advantage of new equipment and recording techniques, including unconventional, home-recorded samples, which were programmed through Casio FZ-1 synthesizers. The album was recorded in New York City at Skyline Studios, which was better equipped than studios the band had worked in previously.
Promotion for Flood included television appearances, promotional videos, and an international tour. The album's mainstream promotion and success contributed to its status as the band's most well known album. Many fans, including young viewers of Tiny Toon Adventures, were first exposed to They Might Be Giants's music through Flood.
Per Yngve Ohlin (16 January 1969 – 8 April 1991), better known by his stage name Dead, was a Swedish black/death metal vocalist and lyricist best known for his work with Norwegian black metal band Mayhem. He also performed as vocalist of the Swedish death metal band Morbid on their demo December Moon.
Roadrunner Records ranked him No. 48 out of 50 of The Greatest Metal Front-Men of All Time.
Per Ohlin (sometimes called "Pelle") was born in 1969 in Stockholm, Sweden. As a young child, he suffered from sleep apnea. At the age of ten, he suffered internal bleeding when his spleen ruptured, after what he alleged was an ice skating accident. In the Swedish metal book Blod eld död however ('Blood Fire Death', named after Swedish band Bathory's fourth album Blood Fire Death), his brother said in an exclusive interview that Dead was bullied in school and one day the beatings got out of hand causing the ruptured spleen. He had to be rushed to a hospital, where he was for a time clinically dead.
Dead is a live album by American death metal band Obituary. The title is a comical reference to its being a "live" album.
