0HTML5 LogoResponsive lazy backgrounds instead of css background-image

Published by & filed under Web Technologies. Last updated .

I’ve recently been work­ing on an update/overhaul of both my vari­ous web­sites and the serv­er backend.

0Optimising WAN MTU for BT Infinity

Posted by & filed under Web Technologies.

Since switch­ing from my BT SmartHub to a pfsense router I’ve had a few minor teeth­ing prob­lems. One of which has been the squid proxy ser­vice caus­ing a prob­lem where I can­’t access the BBC web­site with an error.
