So I actually rarely encounter any problems with my Arch Linux, but sometimes they just want to see the world burn. Apparently after updating the mesa driver, so library got lost.

Easy fix:

# Arch Linux
mv ~/Android/Sdk/tools/lib64/libstdc++/libstdc++.so.6{,.bak}
mv ~/Android/Sdk/tools/lib64/libstdc++/libstdc++.so.6.0.18{,.bak}
ln -s /usr/lib/libstdc++.so  ~/Android/Sdk/tools/lib64/libstdc++/

Thanks to proft.me for providing this!

In this series of posts I’ll document useful git commands ready to copy&paste which nobody knows by heart but you need once in a while. Today:

git remote prune <name>

From the docs:

prune

Deletes all stale remote-tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in “remotes/<name>”.

git remote prune origin

Sometimes its useful to show data received / processed through PHP in the browser for debugging purposes. Yes you can use Firebug or some of those fancy debugging classes, but maybe you just want to view that damn array quickly 🙂 Use this: function dumpMe($arr) { echo str_replace(array(“\n”, ‘ ‘), array(‘ ‘, ‘ ‘), print_r($arr, true)) . ‘ ‘; }  

The Api of PHP just rocks, easy to use for the things you need. Sometime compatibility is an issue though. Many webhosters didn’t upgrade yet from 5.3 to anything reasonable, so I might as well keep this snippet here for future reference: if (!function_exists(‘http_response_code’)) { function http_response_code($newcode = NULL) { static $code = 200; if ($newcode !== NULL) { header(‘X-PHP-Response-Code: ‘ . $newcode, true, $newcode); if (!headers_sent()) { $code = $newcode; } } return $code; } }  

Useful when converting between those two formats often: function formatDateMysql($timestamp = false) { if ($timestamp === false) { $timestamp = time(); } return date(‘Y-m-d H:i:s’, $timestamp); } in the other direction you can use the mighty strtotime function, o god I love PHP so much <3 (Yes Java, your Date object is a mess!)

In order to use RBL lists on your postfix setup to block spam replace this line in main.cf: smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf   with: smtpd_sender_restrictions = reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client cbl.abuseat.org, reject_non_fqdn_sender, reject_unknown_sender_domain, check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf   You can copy and paste the line with any ISPConfig setup. If you don’t use mysql to authenticate your users then you might need to adapt parts of this setting.
