Stefan Karpinski
Stefan Karpinski is an American computer scientist known for being a co-creator of the Julia programming language. He is an alumnus of Harvard and works at Julia Computing, which he co-founded with Julia co-creators, Alan Edelman, Jeff Bezanson, Viral B. Shah as well as Keno Fischer and Deepak Vinchhi. He received a B.A. in mathematics from Harvard in 2000, and has completed much of the work on a PhD in computer science from UCSB with research on modeling local area network traffic. He is one of the four main authors of core academic papers on Julia. He speaks regularly on Julia at industry events on scientific computing, programming languages, and data science. In 2006, Karpinski participated in the Subway Challenge, holding for some time the Guinness World Record for the fastest transit stopping at all New York City Subway stations. Awards In 2019, Stefan Karpinski was awarded the J. H. Wilkinson Prize for Numerical Software with Jeff Bezanson and Viral B. Shah for their w ...

Harvard
Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees. Harvard has three main campuses: the Cambridge campus centered on Harvard Yard; an adjoining campus immediately across Charles River in the Allston neighborhood of Boston; and the medical campus in Boston's Longwood Medical Area. Harvard's endowment is valued at $50.9 billion, making it the wealthiest academic institution in the world. Endowment inco ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ...

Julia (programming Language)
Julia is a high-level, dynamic programming language. Its features are well suited for numerical analysis and computational science. Distinctive aspects of Julia's design include a type system with parametric polymorphism in a dynamic programming language; with multiple dispatch as its core programming paradigm. Julia supports concurrent, (composable) parallel and distributed computing (with or without using MPI or the built-in corresponding to "OpenMP-style" threads), and direct calling of C and Fortran libraries without glue code. Julia uses a just-in-time (JIT) compiler that is referred to as "just- ahead-of-time" (JAOT) in the Julia community, as Julia compiles all code (by default) to machine code before running it. Julia is garbage-collected, uses eager evaluation, and includes efficient libraries for floating-point calculations, linear algebra, random number generation, and regular expression matching. Many libraries are available, including some (e.g., for fast Fo ...

Timeline Of Programming Languages
This is a record of notable programming languages, by decade. Prior to 1950 there were 8 unique programming languages, where 6 were unique languages and 2 were combinations of unique languages. By 1960 there were around 45-50 unique programming languages, though only 12 new unique languages (i.e. not relying of already existing programs). A unique programming language hasn't been developed since Swift in 2007. The newest language, Google's Carbon, is a combination of C++ and Rust. As of December 2022, 395 unique programming languages exist, of which 37 are not a combination of other languages and thus fully unique.

New York City Subway
The New York City Subway is a rapid transit system owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the state-run Metropolitan Transportation Authority (MTA). Opened on October 27, 1904, the New York City Subway is one of the world's oldest public transit systems, one of the most-used, and the one with the most stations, with New York City Subway stations, 472 stations in operation (424 if stations connected by transfers are counted as single stations). Stations are located throughout the boroughs of Manhattan, Brooklyn, Queens, and the Bronx. The system has operated 24/7 service every day of the year throughout most of its history, barring emergencies and disasters. By annual ridership, the New York City Subway is the busiest rapid transit system in both the Western Hemisphere and the Western world, as well as the List of metro systems, seventh-busiest rapid transit rail system in the world. In , the subway deliv ...

Subway Challenge
The Subway Challenge is a challenge in which participants must navigate the entire New York City Subway system in the shortest time possible. This ride is also known as the Rapid Transit Challenge and the Ultimate Ride. Although the challenge requires competitors to stop at all stations, no person currently holds that record. One competitor holds the record for 469 stations, as he had competed before the January 2017 opening of the Second Avenue Subway. Three teams held the Guinness record for 468 stations, as they had competed prior to both the September 2015 opening of the 7 Subway Extension and the January 2017 opening of the Second Avenue Subway, but after Dean Street station was closed in 1995. Records set before 1995 had a varying number of stations. There are three primary variations of this challenge: # Ride that requires a rider to traverse every line, but not necessarily the entire line. (Class A) # Full-system ride that requires a rider to stop at each station. (Cla ...

Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring and AppleTalk. History The increasing demand and usage of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethe ...
