A bit of a dry post here, but I thought I’d share my experience of trying to get two instances of MySQL (and two different versions, to boot) running simultaneously on a single piece of hardware… Continue reading Multiple MySQL Servers on a Single Machine

The… Continue reading Plotting & iGraph on Lion and Mountain Lion
