A collection of links for streaming algorithms and data structures

General Background and Overview

  1. Probabilistic Data Structures for Web Analytics and Data Mining : A great overview of the space of probabilistic data structures and how they are used in approximation algorithm implementation.
  2. Models and Issues in Data Stream Systems
  3. Philippe Flajolet’s contribution to streaming algorithms : A presentation by Jérémie Lumbroso that visits some of the hostorical perspectives and how it all began with Flajolet
  4. Approximate Frequency Counts over Data Streams by Gurmeet Singh Manku & Rajeev Motwani : One of the early papers on the subject.
  5. [Methods for Finding Frequent Items in Data Streams](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.187.9800&rep=rep1&t

proof-of-concept pre-rendering d3.js svgs on the server using node.js and jsdom module.
// pre-render d3 charts at server side
var d3 = require('d3')
, jsdom = require('jsdom')
, fs = require('fs')
, htmlStub = '<html><head></head><body><div id="dataviz-container"></div><script src="js/d3.v3.min.js"></script></body></html>'

, html : htmlStub

EtherCalc Chapter for the upcoming book "The Performance of Open Source Applications" - Draft - comments welcome!

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.

For the Socialtext team, performance was the primary goal behind SocialCalc's design in 2006. The key observation was this: Client-side computation in JavaScript, while an order of magnitude slower than server-side computation in Perl, was still much faster than the network latency incurred during AJAX roundtrips:

# Install from Source - at this time ubuntu's universe only install version 0.8 using sudo aptitude install couchdb so we have to install from source version 0.9*
# IMPORTANT: Couchdb is a pain in the ass to install on ubuntu hardy. Hopefully, you used Jaunty. There is an erlang package issue.
# Install dependencies
sudo apt-get install automake autoconf libtool subversion-tools help2man
sudo apt-get install build-essential erlang libicu38 libicu-dev
sudo apt-get install libreadline5-dev checkinstall libmozjs-dev wget
sudo apt-get install libcurl4-openssl-dev
# Get Couchdb
