Chris Mattmann
Chris Mattmann (born October 29, 1980) is an American data scientist currently working as the Principal Data Scientist and Chief Technology and Innovation Officer in the Office of the Chief Information Officer (OCIO) at the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California. He is also the manager of JPL's Open Source Applications office. Mattmann was formerly Chief Architect in the Instrument and Data Systems section at the laboratory. Mattmann graduated from the University of Southern California (USC) in 2007 with a PhD in Computer Science studying with Dr. Nenad Medvidović and he went on to invent Apache Tika with Jérôme Charron. Apache Tika is a widely used software framework for content detection and analysis. Mattmann later wrote a book about the framework titled Tika in Action with Jukka Zitting, which is published by Manning Publications. Chris Mattmann's work on Tika and other projects was heavily influenced by open source both at NASA and within the acad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Clarita, California
Santa Clarita (; Spanish for "Little St. Clare") is a city in northwestern Los Angeles County in the U.S. state of California. With a 2020 census population of 228,673, it is the third-largest city by population in Los Angeles County, the 17th-largest in California, and the 99th-largest city in the United States. It is located about northwest of downtown Los Angeles, and occupies of land in the Santa Clarita Valley, along the Santa Clara River. It is a notable example of a U.S. edge city, satellite city, or boomburb. Human settlement of the Santa Clarita Valley dates back to the arrival of the Chumash people, who were displaced by the Tataviam circa 450 AD. After Spanish colonists arrived in Alta California, the Rancho San Francisco was established, covering much of the Santa Clarita Valley. Henry Mayo Newhall purchased the Rancho San Francisco in 1875 and established the towns of Saugus and Newhall. The Newhall Land and Farming Company played a major role in the city's de ...

Orbiting Carbon Observatory 2
Orbiting Carbon Observatory-2 (OCO-2) is an American environmental science satellite which launched on 2 July 2014. A NASA mission, it is a replacement for the Orbiting Carbon Observatory which was lost in a launch failure in 2009. It is the second successful high-precision (better than 0.3%) observing satellite, after GOSAT. Mission overview The OCO-2 satellite was built by Orbital Sciences Corporation, based around the LEOStar-2 bus. The spacecraft is being used to study carbon dioxide concentrations and distributions in the atmosphere. OCO-2 was ordered after the original OCO spacecraft failed to achieve orbit. During the first satellite's launch atop a Taurus-XL in February 2009, the payload fairing failed to separate from around the spacecraft and the rocket did not have sufficient power to enter orbit with its additional mass. Although a Taurus launch was initially contracted for the reflight, the launch contract was cancelled after the same malfunction occurred on the l ...

Computer Science Writers
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations ( computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

21st-century American Engineers
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, ...

NASA People
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for ...

Memex
Memex is a hypothetical electromechanical device for interacting with microform documents and described in Vannevar Bush's 1945 article "As We May Think". Bush envisioned the memex as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility". The individual was supposed to use the memex as an automatic personal filing system, making the memex "an enlarged intimate supplement to his memory".. The name memex is a portmanteau of ''mem''ory and ''ex''pansion. The concept of the memex influenced the development of early hypertext systems, eventually leading to the creation of the World Wide Web, and personal knowledge base software. The hypothetical implementation depicted by Bush for the purpose of concrete illustration was based upon a document bookmark list of static microfilm pages and lacked a true hypertext system, where parts of pages would have internal ...
