In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

$ brew update
$ cd `brew --prefix`

# Use erlang formula for Erlang R15B01
$ git checkout 6b8d25f Library/Formula/erlang.rb
$ brew install erlang

# Reset formula
$ git reset HEAD Library/Formula/erlang.rb
$ git checkout -- Library/Formula/erlang.rb

A friend asked me for a few pointers to interesting, mostly recent papers on data warehousing and "big data" database systems, with an eye towards real-world deployments. I figured I'd share the list. It's biased and rather incomplete but maybe of interest to someone. While many are obvious choices (I've omitted several, like MapReduce), I think there are a few underappreciated gems.

###Dataflow Engines:

Dryad--general-purpose distributed parallel dataflow engine

Spark--in memory dataflow

Context: I was asked for a list of interesting reading relating to "distributed databases, behavior under partitions and failures, failure detection." Here's what I came up with in about an hour.

For textbooks, "Introduction to Reliable and Secure Distributed Programming" is a superb introduction to distributed computing from a formal perspective; it's really not about "programming" or "engineering" but about distributed system fundamentals like consensus, distributed registers, and broadcast. Used in Berkeley's Distributed Computing course (and HT to @lalithsuresh) Book Site

Notes from courses like Lorenzo Alvisi's Distributed Computing class can be great.

There are a bunch of classics on causality, [Paxos](ht

My efforts to port http://www.youtube.com/watch?v=f6kdp27TYZs to Clojure.

A boring function (6:22)

func boring(msg string) {
  for i := 0; ; i++ {
    fmt.Println(msg, i)
    time.Sleep(time.Second)

This code is adapted from the consensus best practice python Twitter feed 
consumer that's been floating around for a while now on StackOverflow etc. 
My only addition to speak of is TenminWriter. (A "tenmin" is ten minutes 
worth of stream. It's just a convenient chunk; you might want to make it 
shorter or longer.)

THERE ARE BUGS HERE. THIS IS BARELY TESTED. DO NOT TRUST IT.
