Richard P. Gabriel (born 1949) is an American computer scientist known for his work in computing related to the programming language Lisp, and especially Common Lisp.His best known work was a 1990 essay "Lisp: Good News, Bad News, How to Win Big", which introduced the phrase Worse is Better, [1] and his set of benchmarks for Lisp, termed Gabriel Benchmarks, published in 1985 as Performance and ...
If multiple surfaces face towards the camera, then additional use of methods such as Z-buffering or the Painter's algorithm may be necessary to ensure the correct surface is rendered. Back-face culling is typically quite a cheap test, only requiring a dot product to be calculated, and so it is often used as a step in the graphical pipeline that ...
A PETR is typically used when a LISP site needs to send traffic to non-LISP sites but the LISP site is connected through a service provider that does not accept nonroutable EIDs as packet sources. Proxy ITR (PITR) : A PITR is used for inter-networking between Non-LISP and LISP sites, a PITR acts like an ITR but does so on behalf of non-LISP ...
In some posts there, he has expressed his opinion on open-source software, including open source implementations of Lisp and Scheme, as something that should be judged individually on its essential merits, rather than automatically considered good merely by being free or open.
The Common Lisp HyperSpec is a technical standard document written in the hypertext format Hypertext Markup Language . It is not the American National Standards Institute (ANSI) Common Lisp standard, but is based on it, with permission from ANSI and the International Committee for Information Technology Standards (INCITS, X3). [ 1 ]
Although many commercial Common Lisp implementations actually support it, it doesn't seem to have seen a lot of use. But in the past couple years, an open-source implementation of CLIM, McCLIM – now hosted at Common-Lisp.net [5] – has been picking up steam lately, so we may be on the verge of a CLIM renaissance. – From Practical Common ...
The former Disney Channel star then stepped back to show off a massive tear near the groin area of his pants as he held them up to the camera. “This is what happened to my pants,” he said ...
Common Lisp is sometimes termed a Lisp-2 and Scheme a Lisp-1, referring to CL's use of separate namespaces for functions and variables. (In fact, CL has many namespaces, such as those for go tags, block names, and loop keywords). There is a long-standing controversy between CL and Scheme advocates over the tradeoffs involved in multiple namespaces.
