Ruby Weekly Issue 39
April 28, 2011
Welcome to issue 39 of Ruby Weekly. I've got a Royal wedding to prepare for (as if - it's really some kidney pain holding me back! :-)) so let's get straight to work:
Headlines
The Rails Hotline: A Free Rails Help Service
The Rails Hotline is a FREE helpline run by volunteer Ruby and Rails developers (who vary throughout the day - only 1 on at time of writing, so be kind). I've been hearing good things about this, so if you have a question, call (877) 817-4190 now (or a bit later when it's quieter!)
Owning Rails: An 8 Hour Rails Masterclass with Marc Andre Cournoyer
Marc Andre Cournoyer (of Create Your Own Programming Language fame) is running a 2 day, 8 hour Rails masterclass in May - should be good! Only 20 seats but I've already lined up 6 from him and this e-mail is going out to 4939 folks, so check it out now if you're genuinely intrigued.
Haml and Sass 3.1 Released (Separately)
Nearly a year after the release of Haml and Sass 3.0 comes the release of 3.1. Notably, they're now separate gems and can be used totally separately of each other. Quite a few new features for each - dig in here.

What's New in Edge Rails: ActiveRecord Identity Map

A problem, though, is that two identical records from the database still results in two in-memory objects being created. The new 'identity map' helps with this issue.
I Am Using Automator, And So Should You
Joshua Lindsey demonstrates how to use Ruby with Mac OS X's 'Automator' tool to build system-wide helper services. It's not heavy on the Ruby but you could take these ideas a long way.
AWK-ward Ruby: What Ruby and Perl Took From AWK
Ryan Tomayko looks at Ruby and Perl's lineage of 'borrowed' features and arrives at Unix's AWK text processing tool. An intriguing essay.
The Rails jQuery-UJS Adapter is Now 'Interactive'
Steve Schwartz talks about the Rails jQuery UJS adapter (aka jquery-ujs), a library that adds unobtrusive JavaScript support to jQuery under Rails, and shows how it's switched from a single, monolithic closure to being something you can extend and interact with more directly.
Using interactive_editor with IRB for an 'inside-out' Ruby IDE

Seen this getting some love on Twitter lately.. it's a new project by Gary Bernhardt where he records a screencast each week on a Ruby, Unix, Git (etc) related topic and you pay $9 per month for the privilege. I've only seen the free sample so far but it looks like an interesting project (and I'm getting no kickback for this :-)).
