Programming languages

edit

Dinechin 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]

XL programming language

edit

Dinechin is the designer of the XL programming language and associated concept programming methodology.[4] "XL" is named for "eXtensible Language".

XL features programmer-reconfigurable syntax and semantics. Compiler plug-ins can be used to add new features to the language. A base set of plug-ins implements a relatively standard imperative language. Programmers can write their own plug-ins to implement application-specific notations, such as symbolic differentiation, which can then be used as readily as built-in language features.

Similar works

edit

There are projects that exploit similar ideas to create code with higher level of abstraction. Among them are:

Video games

edit

As initial developer of Alpha Waves, a "groundbreaking" Atari ST game (listed in the Guinness World Records as the first 3D platform game[5]), de Dinechin heavily influenced Frederick Raynal, the main developer of Alone in the Dark.[6] de Dinechin also wrote a few viral games for HP-48 calculators,[7][8] and was the first person to take advantage of hardware-scrolling on these machines.[9]

Operating systems design

edit

In the early 2000s, he worked as a software architect for HP-UX,[10] 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.[11]

Since 2022, he also is the initiator and maintainer of DB48X, a new implementation of RPL.[12][13]

Other work

edit

Christophe de Dinechin did the initial port of Emacs to the Aqua user interface.[14] He wrote a variety of open-source drivers for the HP DE200C Digital Entertainment Center,[15] turning it from a web-connected CD Player into a true digital video recorder.

Between 2010 and 2017, Christophe de Dinechin was the CEO of Taodyne, a company developing a 3D animation tool, using a derivative of his XL programming language called Tao3D to describe dynamic documents.[16]

Bibliography

edit

Dinechin has published three books:

  • A French science-fiction novel called Informagie[17]
  • A French book about physics called Réunifions la physique[18]
  • A physics book called A theory of incomplete measurements[19]
