Second Xamuel.com Linkfest

It’s that time again, time for another irregular linkfest. I’m still getting the hang of running these. Maybe this batch is a bit larger than I was anticipating. I guess two weeks is too long a period when there’s so much interesting material to share :)

The previous linkfest is here: The First Xamuel.com Irregular Linkfest
