An interesting tool for numerical computation and data analysis, based on OCaml. Its author, David McClain designed the Lisp-based Siglab system afterwards. Interfaces exist for C/C++, VBasic, OCaml, Dylan, Mathematica, Lisp, and Scheme.
Marc Feeley demonstrated how to write a simple Scheme to C compiler, in Scheme. In only 90 minutes! Presentation material (slides?), source code and video (200MB) are available.
A graphical programming environment based on CL. Originally for music composition/generation, it might be interesting for other (DSP) tasks. Currently (2006-08-06) it runs under MCL/Mac OS X and Right now, OpenMusic runs on the following platforms:
Another (after Kevin Layer's) EXIF facility in CL. The documentation (dictionary) looks nice--was it generated by a tool? TODO: register Kevin's version in the common lisp directory
Lisp Lab Austria short LiLA is a group of loosely affiliated developers and users of Common Lisp. Knowledge exchange, organization of events, and the general promotion of the language is our goal. LiLA is open, informal, and everybody is welcome t Off-line as of 2013-03-17.
This is a collection of information (mostly links) about (Common) Lisp, using a system written in CL. While I am far from understanding it, I think that valuable ideas can be found here.
