Hi Dan. I worked at Webster Research for Xerox ('72-80) hauling PARC
Altos and tech to our labs. Our printer software group worked on the
Multi-Project Chip with a pre-print of the Conway/Mead VLSI book
building a compressor/decompressor component for the band-based
(memory striped) printers. Peter and Alan were very instrumental in
helping getting ST used at WARC.
Then off to Apple, then Sun, and now retired and out of harms way in
Santa Fe. Interestingly enough, Randy Smith (Morphic/Self) was my
last partner at Sun.
Our (Redfish & the SF Complex) recent Seaside workshop was really
wonderful, both in the joy of Squeak and seeing how it can be used in
the web-app world. Our goal is to build a really distributed Agent
Based Modeling world -- objects/agents which have geospatial awareness
Do you have any pointers to how you tamed JS? Your object style? It
looks like the JS world has several object models from "classical" to
"prototypal". The LK browser has been very helpful.
One interesting problem we've run into is that almost all the JS
libraries (Prototype, YUI, jQuery, ..) *presume* a DOM! Gawd. But
then it makes sense, given the history. I'm a bit surprised at that.
Prototype, and likely the others, do have a modular design that lets
you choose good non-DOM subsets from their repositories.
