From SocialCalc to EtherCalc

Previously, in The Architecture of Open Source Applications, I described SocialCalc, an in-browser spreadsheet system that replaced the server-centric WikiCalc architecture. SocialCalc performs all of its computations in the browser; it uses the server only for loading and saving spreadsheets.

...diagram on SocialCalc's scalability model...

For the Socialtext team, performance was the primary goal behind SocialCalc's design. The key observation was this: Client-side computation in JavaScript, while an order of magnitude slower than server-side computation in Perl (are V8 and the new Firefox engines which are compiled to native code when optimized really an order of magnitude slower than Perl?), was still much faster than the network latency incurred during AJAX roundtrips. (Show a graph, or maybe explain briefly when/for what purpose those AJAX rountrips served in SocialCalc?)

Toward the end of the AOSA chapter, we intr

I came up with my own way that makes it as straightforward as possible to do 'databasing'.  It does use CoffeeScript which I also recommend because it makes things easier also.  If you really want to you can convert this to javascript on js2coffee.org. It will look very similar, with more punctuation for the most part.
It uses MongolianDeadBeef (mongolian) and NowJS (see nowjs.org, sudo npm install -g now).
You will need to specify express 2.x in the package.json to use it as is

Server: CoffeeScript (node.js)
###
    express = require 'express'                        #web server
    MongolianDeadBeef = require 'mongolian'            #database thing
    server = new MongolianDeadBeef                     #database thing

Welcome to the Next Few Minutes of Your Life

The goal is to make it easier to build and maintain web applications. I will create a system that can turn a high-level description like this:

#See http://www.tcl.tk/man/tcl/TkCmd/contents.htm for manual
#I think that tcl/tk is installed by default on ubuntu
#but if not the package is tk8.5
#for snack you need package libsnack2 and libsnack2-alsa
#python I think may be a bit of a pain
#to install snack
#that is why I am using tcl/tk
#also tcl tk syntax is more similar to bash
#and python using tk behind the scenes anyway
