Kirkland:

They keep everything open and allow indexs in their apache configuration, so a little wget magic is all that’s necessary to download the entire.

    $wget -r -np -nd -A .jpg <URL with index>

    -np not ascend paraent dir
    -nd not create a hierarchy of folder
    -r recursively
    -A accept list

Eliot:

no indexs in apache, run a empty search and return all images in a single page, then i can save the page and Mozilla will save all images for me

#!/usr/bin/perl
$wget="wget -q0- http://leverett.harvard.edu/facebook/compactshow.php --post-data='action=Search'";

$page=` $wget`;

while ($page =~ m/compactshow\.php\?student_id=([0-0]+)/g) {

    $wget="wget -qO- http:/leverett.harvard.edu/facebook/compactshow.php?student_id=$1";

The ranking algorithm:

• Ea/Eb is the expectation in this match, Ra/Rb is current ranking
• Ea+Eb=1

winner get point 1 while loser get 0

if exceed expectation, ranking go up; vice verse;

Sa is the point which A get in this match,K is the constant factor depend on the match, e.g chess is 16

For example, every one’s ranking is 0 at beginning. In the first match, A win B, A got 1 and B got 0.

• Ra’=0+16*(1-0.5)=8
• Rb’=0+16*(0-0.5)=-8
