Microsoft has developed open-source reference C# compilers and tools. The first compiler, Roslyn, compiles into intermediate language (IL), and the second one, RyuJIT, [119] is a JIT (just-in-time) compiler, which is dynamic and does on-the-fly optimization and compiles the IL into native code for the front-end of the CPU.

Charles Simonyi (/ s ɪ ˈ m oʊ n i /; Hungarian: Simonyi Károly, pronounced [ˈʃimoɲi ˈkaːroj]; born September 10, 1948) is a Hungarian-American software architect.. He introduced the graphical user interface to Bill Gates for the first time who later described it as the first of two revolutionary things he felt in his life.
The first high-level language to have an associated compiler was created by Corrado Böhm in 1951, for his PhD thesis. [3] The first commercially available language was FORTRAN (FORmula TRANslation), developed in 1956 (first manual appeared in 1956, but first developed in 1954) by a team led by John Backus at IBM.
A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such program is often the first written by a student of a new programming language, [ 1 ] but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source ...
Thomas Eugene Kurtz (February 22, 1928 – November 12, 2024) was an American computer scientist and educator. A Dartmouth professor of mathematics, he and colleague John G. Kemeny are best known for co-developing the BASIC programming language and the Dartmouth Time-Sharing System in 1963 and 1964.
Tomlinson was asked to change a program called SNDMSG, which sent messages to other users of a time-sharing computer, to run on TENEX. [20] He added code he took from CPYNET to SNDMSG so messages could be sent to users on other computers—the first email. [21] The first email Tomlinson sent was a test.
He created the first commercially available portable computer, the Osborne 1, released in April 1981. It weighed 24.5 pounds (12 kg), cost US$1795—just over half the cost of a computer from other manufacturers with comparable features—and ran the popular CP/M 2.2 operating system . [ 7 ]
