- THE HISTORY OF FORTRAN I, II, AND III (computerhistory.org)
Before 1954 almost all programming was done in machine language or assembly language. Programmers rightly regarded their work as a complex, creative art that required human inventiveness to produce an efficient program. Much of their effort was devoted to overcoming the difficulties created by the computers of that era: the lack of index registers, the lack of built-in floating point operations, restricted instruction sets (which might have AND but not OR, for example), and primitive input-output arrangements. Given the nature of computers, the services which “automatic programming” performed for the programmer were concerned with overcoming the machine’s shortcomings. Thus the primary concern of some “automatic programming” systems was to allow the use of symbolic addresses and decimal numbers (e.g., the MIDAC Input Translation Program [Brown and Carr 1954]).
- Cretaceous (Wikipedia)
The Cretaceous (IPA: /krɪˈteɪʃəs/ krih-TAY-shəs) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin creta, “chalk”, which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation Kreide.
