[dorkbotpdx-blabber] REMINDER: Pd workshop this Sunday.

[Ward Cunningham]

I've had a long term interest in practical code generation for the  
AVR. I believe that C offers a less than ideal abstraction. For  
example, I could not write my video bar chart program in C and squeeze  
it into a Tiny12 at 1 MHz. But then I ask, what would I like to write  
that program in so as to avoid the usual mistakes associated with  
assembly language. Some conclusions:

* The AVR programmer's primary task is one of resource allocation and  
configuration, not logic or algorithm.
* When a resource is exhausted (say registers) the generator should  
not forge ahead wasting bytes and cycles, better it say: simplify your  
program.

Codosome-2 is a prototype cross-compiler for the AVR that builds a  
java object model of the program being assembled and allows one to  
test and refactor program fragments as the compiler runs. I have  
successfully compiled a variation of "tiny tv" with it.

I am thinking about what Codosome-3 should be. I would like to make it  
a server based tool (probably in rails, but maybe scala) that uses  
advanced web programming (probably in jQuery) to configure library  
components/generators in an edit/download cycle of only a few seconds.  
I'm attracted to a web implementation because it simplifies sharing  
(inspired by wiki).

I would be interested in collaborating with folks on such a project,  
especially if they are more interested in exploring a new space than  
getting done quickly.

Best regards. -- Ward
