Setup new Mac with OSX Lion from scratch

These commands are good as of 2011-07-27.

Install xcode 4

App store http://itunes.apple.com/us/app/xcode/id448457090?mt=12) The download/install takes awhile so start it first. When it finishes downloading you will still need to run it to complete installation.

The INSTALL instructions that come with Vowpal Wabbit appear not to work on Mac OS X Lion. Here's what I did to get it to compile. You will need the developer tools that come with the XCode installation.

The only dependency VW has is the boost C++ library. So first, download and install Boost

To install Boost, do the following:

$ cp ~/Downloads/boost_1_48_0.tar.bz2 ./

# Utilities for quickly accessing frequently used directories in bash.

# Usage:
#   $ cd /path/to/project/src/
#   $ mark code     # Will create a new shortcut.
#                   # Becomes interactive if a shortcut already exists
#                   # m is an alias for mark. You can also `m code`
#
#   $ code          # From now on, running this anywhere in the shell
#                   # will put you in /path/to/project/src/code

using reputation systems to create shared function-critical datastructures in open networks

Search engines, spam filtration, and p2p protocols - all need to rate the value of information. Search engines need it to provide good results; spam filtration needs it to exclude noise; and p2p networks need it for security and efficiency.

What is "value?" I'll use two dimensions:

• Quality (how useful the information is). The more permissive participation is, the greater the need for quality-ranking. Term-frequency search alone fails for the Web, because the Web doesn't prefilter for quality.
• Trust (how safe the information is to use). The more function-critical the information is, the greater the need for trust-ranking. If a DHT's host-lookup can be manipulated to flood an unsuspecting computer (a DDoS) then the DHT is unsound.
