Everything about Mike Cowlishaw totally explained
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 a Fellow of the
Royal Academy of Engineering (roughly the equivalent of the
NAE in the USA), the
Institute of Engineering and Technology (formerly IEE), and the
British Computer Society.
Career at IBM
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 programming language (published in
IBM Systems Journal in 1984) and the
NetRexx programming language (1996-7), his work on color perception and image processing (198?-1985), 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, SGML applications,
PMGlobe
, the IBM Jargon file (
IBMJARG) through 1990,
Java-related languages, the
Acorn System 1 simulator,
MemoWiki, and
decimal arithmetic.
He has also contributed to and/or edited numerous computing standards, including
ISO (
SGML,
COBOL,
C,
C++),
BSI (SGML, C),
ANSI (REXX),
IETF (
HTTP 1.0/RFC 1945),
W3C (
XML Schema),
ECMA (
ECMAScript,
C#,
CLI), and
IEEE (
754r floating-point).
Decimal arithmetic
In recent years, he's 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. Cowlishaw's
decimal arithmetic specification seems to be the basis for the decimal parts of the
IEEE 754r standard revision, as well as being followed by many implementations, such as
Python and
SAP Netweaver. 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 are integrated into the
IBM Power6 and
IBM System z10 processor cores., and in numerous IBM software products such as
DB2,
TPF (in
Sabre),
WebSphere MQ, operating systems, and C and PL/I compilers.
Other activities
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 .
