Conrad Barski and James Webb: Casting SPELs in Emacs Lisp

Conrad Barski’s awesome Lisp tutorial Casting SPELs is now also available in an Emacs Lisp version, edited by James Webb. Even if Emacs Lisp is certainly not the greatest Lisp dialect, it shouldn’t matter much for a beginner’s tutorial and it sure is nice to be able to evaluate everything right in your editor.

ars technica: Tentacular, tentacular!

Cthulhu plucked a manila folder from somewhere within the non-Euclidean geometry of his manbag and dropped it on my desk with a thud.

A geeky, hilarious choose-your-own-adventure story written by Cthulhu. What else could you want for your Easter weekend.


Land of Lisp


I’m pretty excited about an upcoming book, Conrad Barski’s Land of Lisp. The book will teach Lisp through implementing and refining a couple of games, and it will feature a back story told in lots of cartoons. Sounds like fun!

The publisher now has a video recording of Conrad’s presentation at Philly Lambda online. I watched it last night, and am even more intrigued now. Conrad shows some awesome comic panels and some really interesting code. Besides hilarious games such as Grand Theft Wumpus, lots of other software from a web server to an SVG generator will be implemented. One game will be refined in four steps, from a C-in-Lisp-syntax kind of stateful, iterative style to a truly lispy style using macros.

I had the pleasure to meet Conrad at a FringeDC meeting in September, and had a great evening with the fringers. (Not surprisingly, Conrad founded the group; not to mention created the site and all its content and drew the Alien Lisp mascot.) As you might see in the video, Conrad is a witty and unpretentious guy and I’m sure it will show in the book.

SICP in Emacs


Most people reading this will know that Structure and Interpretation of Computer Programs (SICP) by Abelson and Sussman is one of the most well known and recommended books when it comes to core Computer Science, algorithms, and functional programming. Suffice it to say, if you want to explore these areas and enhance your programming on a level beyond knowing the latest framework, check out this book. It’s freely available online, as well as recordings of lectures the authors gave.

Now, in case that’s not nerdy enough for you, I found a version in texinfo yesterday. Complete with all graphics converted to ASCII art. Yes, kinda scary, but it rocks: have your Emacs display an info buffer with the book and a Scheme or CL REPL to play with the book’s code and work on the exercises. Just move around the book and evaluate the code snippets there. Neat!

I guess that means I have to resume my project of working through the exercises. I’m not even sure where my first couple solutions are…
