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.

Slick monadic Actions
package slick
/**
* This is some code extracted from TimeOut codebase, demonstrating:
* - Use of tag typed to avoid mixing session of different DB
* - The use of the Reader Monad to compose Actions together and defer the choice of async/sync computation
*
* I remove the part where we can say if our operation are read only or not (to use different connection), in order to
* make things easier.

A new user's guide to SublimeText 2. Estimated reading time: 2 mins. Estimated workthrough time: 12 minutes.

Make it useful

  • Install Package Control. For SublimeText 2, paste the following in Terminal:
import urllib2,os; pf='Package Control.sublime-package'; ipp = sublime.installed_packages_path(); os.makedirs( ipp ) if not os.path.exists(ipp) else None; urllib2.install_opener( urllib2.build_opener( urllib2.ProxyHandler( ))); open( os.path.join( ipp, pf), 'wb' ).write( urllib2.urlopen( 'http://sublime.wbond.net/' +pf.replace( ' ','%20' )).read()); print( 'Please restart Sublime Text to finish installation')

From here on out, use Package Control to install everything. +Shift+P, then type Install to get a list of installable packages you can 'livesearch through. After installing plugins, they should be running.
