I wanted to let everyone know about the upcoming ANTLR conference. A brand new version, ANTLR 3, is in the works. The upcoming workshop will be heavily focused on refining the design of this -- see http://www.antlr.org/blog/index.tml for design notes.

The workshop is free, even parking is free! It'll be hosted at USF, where Terence Parr, the creator of ANTLR is now a professor. Anyone with the interest is welcome to participate. Please send us an email letting us know you are coming.

The formal announcement page is here: http://www.cs.usfca.edu/ANTLR2004.shtml

I've been meaning to write about this for a while. I still don't have the time to do it up right, but here's a quick core dump.

A couple of weekends ago Terence Parr and Loring Craymer spent a long weekend with me drafting a proposal for new features in ANTLR 3. Notes are here http://www.antlr.org/workshop/cabal-2003/index.html.

It was more intense than any conference I've been to because it was so focused. These are two very bright guys. We came away with a good outline for a document and some interesting solutions to common ANTLR problems. Loring has been hard at work on tree building enhancements which are really powerful. I helped come up with a scheme for code generation from an Abstract Syntax Tree based loosely on lout's galley targets. Aftewards I did some research and found that I "discovered" a way to do dynamic scoping, abandonded years ago by the LISP community because it is so hard to reason about code which changes because of who is calling it. But when you are generating code that can't be called directly it sure is nice. I vaguely recall from the '97 Python conference that Zope does a similar thing.

ANTLR 3 is still quite a ways off, but with Ter at his faculty position now he should be able to devote some serious time to getting it going.

Way cool is that ANTLR the grammar analyzer will produce its results as an intermediate file format which can be used to generate the code. This will allow one to write the Python code generator in Python, etc. I can't wait!

I won!

Qutoed from Bruce Sterling's Viridian Note 00374:

The Viridian "Embrace the Decay" Contest has a winner!
Note these spectacular entries by
David Nelson Epstein, Duncan Stewart, Monty
Zukowski, and Aubrey LaPuerta. http://www.levitated.net/sterling/contest/index.html


 Viridian Contest Judge Lola Brine mellifluously remarks:

 "'Spore Ink' 
Monty Zukowski

 gets my vote.

 "His generative 
generations 
flow 
and grow
so smoothly, like a fluid spill,  
like time lapse in summer,
a winner with his conscious  
technical  merit alone.

 "But more.

 "This decay, growth instead,
reminding me of something inside my head
== of critical
rhetorical
analysis of text:

 "the way it sumptuously, 
greedily 
takes a mere 
scan of a text
and sprouts tangential assertions 
from every 
unexpecting 
line and angle.

 "And from every noun, from every cultural observation...
in a self-asserting stroke of genius masturbation,
it grows stems 
and branches 
and thickens them into trunks
of intellectual ballet and philosophical gunk,

 "a dance,
a sport,
which departs so utterly 
from the text at hand
strangling the life from the author's gest,
making it 
a trellis 
for the critic's best,

 "the text becoming 
a brick wall in effect,
a blackened host, 
for a parasitic, narcissistic
growth of a boast.

 "A flagrant display of literature's helpless decay,
in the mind of the reader who reads words into words
into words
into dogma
into historical relevance
and theoretical smegma,
"'Death to the Author'
the fractals declare.

 "Yes this is my choice:
embrace Monty, the winner!"

Bruce Sterling said "Wow" about my entry for the Embrace Decay Contest. I'm stoked! And I'm working on more entries. This time with color.

Unfortunately that particular Viridian Note is not in the archive yet. I'll post a link when I can.

I've been having quite a bit of fun goofing off and programming my entry for Bruce Sterling's Embrace Decay Contest. The contest starts with a 612x800 jpeg of a typing excersize. The contest is to make a series of images that will fade to each other, showing decay.

I started with Diffusion-limited aggregation and then tweaked it to get something interesting. Take a look at my entry! I used to work at Trilobyte, a game company Graeme Devine cofounded. I had forgotten how much fun it is to program graphics. And how tedious. Consider entering.
