Don't miss the next issue!

Hi,

Lots of videos for you to watch this week, particularly those from the Austrian Perl Workshop, held recently.

You might have noticed that MetaCPAN had a bumpy week, the result of a move to new hardware in a different data centre, hopefully settled now. Olaf tells me they're always looking for volunteers, want to help out?

Think carefully before giving feedback to Gabor on the Perl Weekly — you might find yourself an editor!

Editor #3, Neil
