Daniel L. Weinreb is a programmer and computer scientist. This is a list of Programmers notable for their contributions to software either as original author or architect or for later additions A computer scientist is a person that has acquired knowledge of Computer science, the study of the theoretical foundations of information and computation and their application He attended MIT 1975-1979, graduating with a B. S. in Computer Science and Electrical Engineering, where he wrote EINE. "Eine" can also be a misspelled reference to the word Ein. This was the second implementation of Emacs ever written, and the first implementation of Emacs in Lisp. Emacs is a class of feature-rich Text editors usually characterized by their extensibility Most of the notable subsequent Emacs implementations used Lisp, including Gosling's Gosmacs, Greenberg's Multics Emacs, and of course Stallman's GNU Emacs.
He worked 1979-1980 at Lawrence Livermore National Laboratory on the Amber operating system for the S-1, particularly the file system and the multiprocess scheduler. The Lawrence Livermore National Laboratory ( LLNL) in Livermore California is a scientific research laboratory founded by the University of California in 1952
In 1980 he co-founded Symbolics, developing software for the Symbolics Lisp Machine. Symbolics is a privately held company that acquired the assets of the now-defunct Computer manufacturer Symbolics Inc Symbolics is a privately held company that acquired the assets of the now-defunct Computer manufacturer Symbolics Inc Lisp machines were general-purpose Computers designed (usually through hardware support to efficiently run Lisp as their main software language. He also participated significantly in the design of the Common Lisp language; he was one of the five co-authors of the original spec, "Common Lisp: The Language, First Edition". Common Lisp, commonly abbreviated CL, is a dialect of the Lisp Programming language, published in ANSI standard document Information
In 1988, he co-founded Object Design, where he was one of the architects and implementors of ObjectStore, a leading commercial object-oriented database management system Object Database. ObjectStore is a commercial Object database, which is a specialized type of Database designed to handle data created by applications that use Object-oriented In an object database (also object oriented database) information is represented in the form of objects'' as used in Object-oriented programming. It is still commercially maintained and available from [Progress Software], which bought Object Design (then eXcelon, Inc. ).
In 2002, he joined BEA Systems, where he was Operations, Administraion, and Management Architect for WebLogic. Owned by Oracle Corporation, BEA WebLogic is a J2EE platform product family that includes A J2EE Application server, WebLogic
In 2006, he joined ITA Software, where he is working on a new airline reservation system. ITA Software is a travel industry Software company in Cambridge Massachusetts.
