The other day I went to watch the demolition of the gas tower in Valby, Copenhagen. The demolition was done by detonating a series of explosive charges in the bottom of the tower. By placing and sequencing the explosions the tower was tipped over to the side with high precision, just like taking down a tree. […]
After moving a Joomla 2.5 site to a new URL (i.e. new domain name) the backend (administrator) did no longer let me login as admin (or any other account for that matter).
