Hope everyone enjoyed their long weekend, I know I did. This set of Friday links is late again (what's new) but I thought there were enough important ones to not skip it. More video and audio in this post than usual so hope you have a good pair of headphones. It's a short week so enjoy the limited time you have to make a difference.
