We use PLT Scheme for many analysis and simulation applications. These include sophisticated graphical outputs and visualizations (animations). For example, our Socio-Cultural Analysis Tool (S-CAT) includes a user-interface (web based) and knowledge-base developed in Common Lisp and automatic agent generation and agent-based simulation developed in PLT Scheme. <div class="gmail_quote">On Tue, Mar 9, 2010 at 1:22 PM, Ciprian Dorin, Craciun <<a href="mailto:ciprian.craciun@gmail.com">ciprian.craciun@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Hello all! I'm in the position where I'm teaching a Lisp laboratory at my university (undergraduate level). The problem is that all the students are reluctant to this new language and deem it somewhere between a toy and an academic / research language... (I know... I'm a bad teacher :) .) So in order to capture their attention I would like to give them some real-world applications where Lisp (Scheme, Common Lisp, or something derived from Lisp) is a major component. (By real world application I mean something released either as a software product or a web-based system...) (I know that the main reason for learning Lisp is both for it's functional programming style and meta-programming... But try telling this to a bunch of kids who think that knowing PHP, MySQL and the latest and greatest JavaScript library means computer science... :) ) So I know a few ones: * Yahoo Store (early version) done by Paul Graham; * Reddit (written in PLT Scheme and then rewritten in Python); * Y Combinator (Arc over PLT Scheme); * WebBlocks (actually a framework); * any other examples? Replies very much appreciated, Ciprian. _________________________________________________ For list-related administrative tasks: <a href="http://list.cs.brown.edu/mailman/listinfo/plt-scheme" target="_blank">http://list.cs.brown.edu/mailman/listinfo/plt-scheme</a> </blockquote></div>
