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

Skew binary tree with the invariants enforced by the type system, using a nested data type.
{-# LANGUAGE GADTs #-}
type Id = Int
data Path a where
P :: P a -> Path a
Two :: b -> b -> P (Br b) -> (P (Br b) -> P a) -> Path a
data Br a = Br a Id a
data P a = Nil | Zero (P (Br a)) | One a (P (Br a))

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Replace .bashrc, .bash_profile, .profile, etc. with something much more clean, consistent, and meaningful. Now a repo: https://github.com/josephwecker/bashrc_dispatch

# -- DEPRICATED --
# This gist is slow and is missing .bashrc_once
# Use the one in the repo instead! https://github.com/josephwecker/bashrc_dispatch
# (Thanks gioele)
#
# Are you tired of trying to remember what .bashrc does vs .bash_profile vs .profile?
