• Posted Migrating 76 tables out of MS-SQL. Thanks DBIx::Class! to jhannah @ Mutation Grid

  Just another day at the office moving databases into MySQL. 10 lines of DBIx::Class::Schema::Loader make_schema_at() and I'm done. :)

  Usually.

  Unfortunately today the table names "Order" and "Service-tier2" blow up:

  Bad table or view 'Order', i…

• Posted FIXED: DBICSL can't 'can' to jhannah @ Mutation Grid

  One of my client's schemas contains a table which contains a column named 'can'. In his context this is a convenient abbreviation for 'Client Access Number'. In Perl however, ->can() is already spoken for. Since…

• Posted Another Catalyst website goes live (ActivityMD) to jhannah @ Mutation Grid

  Another client launch: ActivityMD.com.

  The front content was WYSIWYG'd by their previous ISP. Prolific position:absolute CSS makes that content painful to edit. But links to the shin…

• Posted Javascript scoping != Perl's to jhannah @ Mutation Grid

  I'm doing a lot of jQuery of one of my current clients. Along the way I'm learning fun Javascript gotchas. Here's a demonstration of one scoping difference. Below the .change() event tied to bar works as I expected, but baz is a global variable.

• Posted One-liner XML / Perl / JSON to jhannah @ Mutation Grid

  castaway blew my mind this morning in irc.perl.org #axkit-dahut.

• Posted Using blogs.perl.org to jhannah @ Mutation Grid

  I stumbled into blogs.perl.org last night. Here's a couple "quick start" tips for using this install of Movable Type Pro:
