Christophe de Dinechin is a French computer scientist, with contributions in video games, programming languages and operating systems.

Programming languages[edit]

The designer of the XL programming language and associated concept programming methodology, de Dinechin also contributed to C++, notably a high-performance exception handling implementation[1] that became a de facto standard in the industry.[2] de Dinechin was one of the proponents of a portable C++ ABI, initially developed for Itanium, but now widely used across platforms.[3]

Video games[edit]

As initial developer of Alpha Waves, a "groundbreaking" Atari ST game (probably the first 3D platform game), de Dinechin heavily influenced Frederick Raynal, the main developer of Alone in the Dark.[4] de Dinechin also wrote a few viral games for HP-48 calculators,[5][6] and was the first person to take advantage of hardware-scrolling on these machines.[7]

Operating systems design[edit]

In the early 2000s, he worked as a software architect for HP-UX,[8] and was the initial designer of HP's virtualisation platform for Itanium servers, HP Integrity Virtual Machines. He was awarded 10 US patents for this work.[9]

Other work[edit]

Christophe de Dinechin did the initial port of Emacs to the Aqua user interface.[10] He wrote a variety of open-source drivers for the HP DE200C Digital Entertainment Center,[11] turning it from a web-connected CD Player into a true digital video recorder.

Christophe de Dinechin is currently CEO of Taodyne, a company that develops a 3D animation tool, using his XL programming language to describe dynamic documents.[12]
