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

by David Farrell (DFARRELL)
David Farrell created Devel::DidYouMean (currently tagged experimental), which “intercepts failed function and method calls, suggesting the nearest matching available subroutines in the context in which the erroneous function call was made”. It was inspired by the did_you_mean ruby gem.

Alex is looking for Brent B. Powers, the author of (amongst others) Tk::FileDialog and Tk::Waitbox. When an author is unresponsive, if you want to help out by taking over a module, you need to go to appropriate lengths to track down the author. This is a good time to remind you: when your email address changes, don't forget to update PAUSE, so people can keep in touch with you.
