Practical Lisp 2008

A little more than three years ago there was a thread in comp.lang.lisp about what people were working on in Common Lisp. I found the replies, some summarized here, quite inspirational; they were from people doing practical stuff (even Real Work) with Common Lisp, beyond things like going through Project Euler or doing exercises from SICP. (Not that those aren't fine things to do, but.)

Let's update this. What are you using Common Lisp for in 2008? What are you using to do it? I'll start:

I mostly use Common Lisp to make graphics toys at Wigflip.com. To that end I'm always looking for new ways to produce or consume graphics-related things. For example, I'm adding support for processing OpenType fonts to ZPB-TTF and making a hybrid of Skippy and Vecto to produce simple vector-oriented animations. I'd also like to add APNG support to ZPNG.

I primarily use SBCL on Linux, x86 and x86-64, with Emacs and SLIME. For deploying all my website stuff I use Edi-ware extensively: Hunchentoot, HTML-TEMPLATE, and CL-WHO. I use CLSQL for a few things too. For graphics work, I use mostly my own libraries.

How about you? Leave a comment and let me know.




web things

I'm (we are three involved) doing a web startup called stix.to (http://stix.to), we create a new layer on top of the internet. It means you can put videos, pictures and texts on top of any page you are visiting, and other people will see what you have added when they get to the same page. A plugin for you browser gets you the full feature set, you can also see pages without any plugin, see our ad on superbowl (http://stix.to/keyhole/*/www.azsuperbowl.com/events.aspx).

We use an old branch of parenscript, and an internal lisp/parenscript integration framework for the things that interact with the plugin. The persistence layer is elephant, to which we made a new postgresql storage backend. The web server we use is the ucw_ajax branch of UnCommonWeb. We use cl-json connected to ucw to make a json-rpc interface for communicating between the browser plugin and server. And of course we use all sorts of other open-source lisp libraries for various things.

On my spare time, I'm doing the usual stuff: Trying to design my own perfect persistence solution, and trying to find a way to make the perfect cpan for Lisp.
