Memcache variable breakdown

30th April, 2014 - Posted by david

At work we use memcache as our local variable cache and the excellent memcache.php from Harun Yayli to give us a simple way of viewing what’s in the cache. One use case we came up with that was missing from the original memcached.php script was a way to group similar variables and see how much […]

Varnish with Apache on Ubuntu, with throttling, logging for multiple sub-sites, handling cookies and more

18th January, 2014 - Posted by david

One of the good things about working in a small company is that you’re more likely to be asked to do things that you’ve never done before and are way out of your comfort zone.
