Mike Cowlishaw
From Wikipedia, the free encyclopedia
Mike Cowlishaw is an IBM Fellow based at IBM UK’s Warwick location, a Visiting Professor at the Department of Computer Science at the University of Warwick, and an elected Fellow of the Royal Academy of Engineering (roughly the equivalent of the NAE in the USA).
Cowlishaw joined IBM in 1974 as an electronic engineer but is best known as a programmer and writer. He is known for designing and implementing the REXX and NetRexx programming languages (published in IBM Systems Journal in 1984), and for his work on color perception, the STET folding editor (1977), the LEXX live parsing editor (1985, possibly the first editor with color highlighting) for the Oxford English Dictionary, electronic publishing and SGML applications, PMGlobe, the IBM Jargon file (IBMJARG), Java-related languages, and decimal arithmetic.
He has also contributed to numerous computing standards, including ISO (SGML, COBOL, C, C++), BSI (SGML, C), ANSI (REXX), IETF (HTTP 1.0), W3C (XML Schema), ECMA (ECMAScript, C#, CLI), and IEEE (754r floating-point).
In recent years, he has been working on aspects of decimal arithmetic; his proposal for an improved Java BigDecimal class (JSR 13) is now included in Java 5.0, and in 2002, he invented a refinement of Chen-Ho encoding known as Densely Packed Decimal encoding (see references). Cowlishaw's decimal arithmetic specifcation seems to be the basis for the decimal parts of the IEEE 754r standard revision. His decNumber decimal package is also available as open source under several licenses and is now part of GCC, and his proposals for decimal hardware have been adopted by IBM and will be in the Power6 processor and others.
Outside computing, he also is known as a caver. A life member of the NSS, he wrote classic articles in the 1970s and 1980s on battery technology and on the shock strength of caving ropes, and caved in the UK, New England, Spain, and Mexico. He still appears to cave in Spain with Speleogroup and designs LED-based caving lamps etc. He also contributes to Wikipedia.
