Just catching up to this now, I think Library Carpentry sounds like a great idea. I did the Software Carpentry instructor training last year and really enjoyed it (though I never formally finished ...). I think the biggest challenge might be in developing a curriculum that appears relevant to library staff. Unix Commands and Batch Processing for the Reluctant Librarian or Archivist http://journal.code4lib.org/articles/9158 Metadata Analysis at the Command-Line http://journal.code4lib.org/articles/7818 These articles make good cases for people in specific roles but I think a successful programme might have to aim wider - or to have general lessons and a more applied choice for those in cataloguing, digital preservation, systems, web design etc.
