This is a short guide to setting up a lisp-powered website with Hunchentoot and Talcl/Buildnode. Hunchentoot is a web server, Talcl is a templating system, and Buildnode is a CXML helper library Talcl uses. These are from notes I made while writing an app to help my wife record attendance and student progress for dance […]

Title cards for videos with Common Lisp
Sunday, June 5, 2011
Xach posted recently about Fighting blog spam with Common Lisp as a short example of using lisp to solve everyday programming problems. Here’s one I made last weekend.

coroutines in common lisp with bordeaux-threads
Sunday, November 21, 2010
Turns out threads are a lot easier without beer and after a good nights sleep. Following up on last night’s defeat (see coroutines in common lisp), I re-read the documentation this morning and got my locks sorted out.

This is a test of the wordpress android app. I am likely too lazy to delete this test later.
more heat-maps using vecto and ch-image
Friday, February 5, 2010
This is a follow-up to my post last year about simplistic heat-maps using Vecto. To recap, I’m trying to make heat maps for google maps overlays. Here’s how it works in a nutshell: From javascript I pass to the server the lat/lng region currently shown on the google map, and what size heat map to […]
