    Notes on slide 1

    Speech opening How many people here EDITED Wikipedia?

    There are so many wikis out there that there’s a wiki comparison engine – Wikimatrix Perl wiki comparison: http://www.wikimatrix.org/compare/Foswiki+ikiwiki+MojoMojo+Oddmuse+PodWiki+Socialtext+TWiki+UseMod

    Wikimatrix lists no less than 120 wikis. I tried to give you a visual Representation of this But I couldn’t fit it all in one slide But anyway, who cares about Ruby or PHP wikis? We’re at YAPC right? So let’s see the Perl wikis

    Turns out there are quite a few Perl wikis as well: commercial or free, old and new, obscure or wildly popular But we still have to choose among these. Now everyone’s criteria are different, but here are some that may be important

    Socialtext is hosted

    Wikipedia has 2.9M page as of today

    “Good” means pages with real content, excluding redirect pages, user pages, talk pages, stubs, help, image description pages, portals

    Page structure At how anal Wikipedia editors are, they WOULD have used a directory type of path if it were available

    So you want to wiki about how people were saying “Aww what a cute dog”, “He is soooo zen”, “Oh look a coffee table that looks like a dog” But in what path?

    Usability is the more important the less technically-inclined your audience is In March 2009, bolt|peters user experience conducted a Wikipedia editing study… … on NON-technical users

    Perl types sometimes just want the damn code. I know I do.

    Markup language: are we stuck with someone’s invention, or can we plug in Markdown, Textile, CREOLE etc?

    Peter Thoeny had changed the access rights to the TWiki.org wiki, locking everyone out from the site unless they agreed to sign up to new terms and conditions. The trademarks to the TWiki name were held by Peter Thoeny who was not willing to license them (on a perpetual basis) to the community. On October 27, 2008, the company TWiki.net eliminated the elected board of directors of TWiki, assumed direct control over the TWiki project, and requested that all contributors agree to a new code of conduct before being allowed to continue working on the project. The bulk of TWiki's active contributors subsequently created a fork of the project named Foswiki . [20] [4]

    Scalability issues with RCS @ Yahoo!

    The preview is better than Foswiki’s in that you see the code under the output on the same page, although you can’t have them side by side, which will start to annoy you ASAP when you edit long pages.

    It looks kinda barebones, and it’s CGI

    I’ll get back to you with details about Storage, Page structure, tags Markup language and preview features as soon as Perl 6 is released.

    The preview is better than Foswiki’s in that you see the code under the output on the same page, although you can’t have them side by side, which will start to annoy you ASAP when you edit long pages. It’s just like MediaWiki’s in this regard.

    PostgreSQL & DBI usage: http://github.com/socialtext/socialtext/blob/09ed67d4b7a711b1dc105ce77f885c3530192deb/nlw/lib/Socialtext/TheSchwartz.pm … but I’m not sure I got the right channel

    This is all of Socialtext’s user base that cared to add themselves there. Notice it’s CGI, and the entire URL isn’t that cool either.

    The preview is better than Foswiki’s in that you see the code under the output on the same page, although you can’t have them side by side, which will start to annoy you ASAP when you edit long pages. It’s just like MediaWiki’s in this regard.

    WebGUI reinvented its own modules to deal with databases, forms, authentication, caching, handling HTTP requests etc.

    Access control is decent Markup languages are OK, even configurable

    Now that the people from the MovableType talk have joined us, we can begin to actually talk about MojoMojo … and plugins for DocBook, syntax highlight, youtube, CAPTCHA

    From classic, to slightly different, to more different, to quite very different

    MojoMojo - the Elegant wiki, Catalyst-powered - Presentation Transcript

    1. MojoMojo The Elegant wiki, Catalyst-powered Dan Dascalescu (dandv) YAPC::NA 2009-Jun-23 Twitter: mojomojowiki
    2. Yet Another Perl Wiki? Not really.
    3. Wikimatrix
    4. … and more
    5. Perl wikis
      • TWiki

    11. When hierarchy doesn’t cut it
      • You encounter this dog in a park in Paris, France
    12. SuperFantastic - “Buddha Dog”, http://www.flickr.com/photos/35423169@N00/50088733 Under what path do you wiki about this?
    13. Q: Which hierarchical path?
      • travel/france/fun
      • travel/fun/france
      • fun/animals
      • fun/travel
      • animals/fun
    14. A: it doesn’t really matter

    15. Editing usability
      • Wikipedia editing study
      Bolt|peters user experience - http://boltpeters.com/wikipedia/
    16. Study finding
      • The vast majority of users pulled up another instance of the Wikipedia page they were editing in order to see what it "really" looked like.
    17. Usability recommendation
      • Provide users a live preview of what the page looks like as the user edits it.
    18. WYSIWYG not a panacea yet
      • Show me the code
      • Crippled - dive demo at Foswiki
    19. Access control
    20. Wiki theory
      • “ Everyone should be able edit any page”
    21. Theory vs. practice
      • In theory, there is no difference between theory and practice. In practice, there is. - Yogi Berra
    22. Wiki practice
      • The Movable Type wiki (the old, unofficial one) was closed down due to vandalism they couldn’t stop. - Deane Barker, Gadgetopia, http://gadgetopia.com/post/6595
    23. Other features
      • Extensibility
      • Markup language
    24. Perl wiki candidates
