9072997 / fib.php
Last active December 19, 2015 10:38
This is an obfuscated command line php program to generate numbers from the fibonacci sequence. The first argument is the starting point and the last is the ending point for the generated numbers, so for example "php fib.php 1 100" would generate the first 100 numbers of the fibonacci sequence. I challenge you to determine the twist in the logic…
<?php $c[1][1]='1';function p($r,$p){global $c;if(isset($c[$r][$p]))$r=
$c[$r][$p];elseif($p==1)$r=$c[$r][$p]=p($r-1,$p);elseif($p==$r)$r=$c[$r]
[$p]=p($r-1,$p-1);else$r=$c[$r][$p]=bcadd(p($r-1,$p-1),p($r-1,$p));
return $r;}function f($s){$l=ceil($s/2);$p=1;$t='0';for($i=1;$i<=$l;$i++
)$t=bcadd($t,p($s--,$p++));return $t;}for($i=$argv[1];$i<=$argv[2];$i++)
echo f($i).' ';?>

Elastissearch reindex-er script in php7
#!/usr/bin/php
<?php
// public domain, requires php curl extensions
// Note: this script can be called with a comma seperated list of
// shards from the source cluster (ex 1,3,4) and it will only pull
// data from those shards. This can allow you to run this script in
// parallell like this:
// For 5 shards, all primary, in 5 threads
// echo $logPrefix . "0 1 2 3 4" | xargs -n 1 -P 100 -- ./reindex.php
