At Bell Labs, Weinberger contributed to the design of the AWK programming language (he is the "W" in AWK), and the Fortran compiler f77. [2] A detailed explanation of his contributions to AWK and other Unix tools is found in an interview transcript at Princeton University. Another interview sheds some light on his work at Google. [3]
AWK (/ ɔː k / [4]) is a domain-specific language designed for text processing and typically used as a data extraction and reporting tool. Like sed and grep , it is a filter , [ 4 ] and it is a standard feature of most Unix-like operating systems .
The AWK Programming Language [1] is a well-known 1988 book written by Alfred V. Aho, Brian W. Kernighan, and Peter J. Weinberger and published by Addison-Wesley, often referred to as the gray book. [2] The book describes the AWK programming language and is the de facto standard for the language, written by its inventors. W.

The method for general multiplication is a method to achieve multiplications with low space complexity, i.e. as few temporary results as possible to be kept in memory. . This is achieved by noting that the final digit is completely determined by multiplying the last digit of the multiplic
It is used in the Pimsleur language learning system and is particularly suited to programmed audio instruction due to the very short times (measured in seconds or minutes) between the first few repetitions, as compared to other forms of spaced repetition which may not require such precise timings. The intervals published in Pimsleur's paper ...
