You're invited to attend a Lisp presentation tomorrow. As posted on http://wiki.alu.org/lispsea ...

Topics in Lisp programming

* Topic: Lisp manipulation of C structures * Presenter: Daniel Pezely * Date: Wednesday, April 11, 2007 * Time: 6:15 - 7:30 PM * Location: Capitol Hill branch of library * Cost: Free and open to the public of all ages

This is for Lisp and non-Lisp programmers alike. Especially those who primarily use other languages may find it interesting to use Lisp for such practical/cookbook tasks.

Within the scope of systems programming, there are often multiple languages being used. While there are verbose file formats for exchanging data among foreign applications, sometimes you still must deal with packed structures within "binary" files or network protocols.

This is about processing and generating packed data records such as those native to C programs.

Specifically, we'll have Lisp reading and writing a C or C++ struct.

We'll also process Unix time values within ANSI Common Lisp, accounting for the different epochs and depending upon hardware architecture, byte order.

This meeting will take place at the Capitol Hill branch of the Seattle Public Library at Harvard Ave E and E Republican St. (This event is not sponsored by The Seattle Public Library.)

Metro Bus within three blocks: 8, 9, 43, 49, 60; within eight blocks: 10, 11, 14, 15.

Parking is free yet challenging on nearby streets or has mandatory "pay station" use on Broadway until 6PM, so best options may be underground garages. There's limited free parking under the Library and a larger commercial garage under QFC grocery store (formerly Fred Meyer) with entrance 1 block away on E Harrison St.

Please! Please! Please silence your gear before entering the building... it's a library, after all!!!

The meeting rooms are upstairs, and we'll be in the large one above the Check-out Desk.

The Library and its garage close promptly at 8 PM. Conversations may continue at various coffee houses, taverns, bars and restaurants in the neighborhood.

For those arriving early, there's Wi-Fi available free of charge and no shortage of things to read...
