    itunes.rb

    655 days ago

    So I never really post any code here. But why not? Who knows. Maybe I’ll start. Here’s a little script I wrote to drive iTunes in an alarm–clock–inspired fashion. It puts me to bed and wakes me up in the morning. Pretty good for 37 LOC huh?

    Rails minutiae

    1516 days ago

    So there isn’t anything harder to take then a subtle bug with little apparent cause. That’s why this sort of thing kills me:

    
/usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/errors.rb:94:in `check': cannot rollback - no transaction is active (SQLite3::SQLException)
        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/resultset.rb:76:in `check'
        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/resultset.rb:68:in `commence'
        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/resultset.rb:61:in `initialize'
        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/statement.rb:158:in `execute'
        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/database.rb:211:in `execute'

        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/database.rb:210:in `execute'
        from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/database.rb:620:in `rollback'
         ... 13 levels...
        from /usr/local/lib/ruby/1.8/test/unit/autorunner.rb:200:in `run'

        from /usr/local/lib/ruby/1.8/test/unit.rb:285
        from test/unit/workout_test.rb:10

    There are time when I’ll just get fed up with the damn computer, and this caused me to wrap up last night and go try to learn to read music1. There was even less information in that error as there is in musical notation! I can almost deal with sound visually on a staff, but it’s real troubling to deal with a bug that won’t leave the slightest clue.

    But I think I’ve got it scrubbed out. Commenting things out strategically leads me to not want fixtures with nil values. Changing this:

    
invalid_exercise:
  id: 4
  name:  
  description:

    into this:

    
invalid_exercise:
  id: 4
  name: ""
  description: ""

    mopped things up real well for me. Now there’s just one more thing that is making me want to bash my laptop with a rock, as soon as I can find it, I’ll be for smooth sailing.

    1 Quite the feat actually: I quit piano in 6th grade because although I could play whatever anyone threw at me by ear, no way did I have the patience to learn to read those goddamned notes.

    Plus he redesigned his site and now it looks exactly like one I’m working on now. His titles are darker blue, and there’s a little triangle on the left, but otherwise the same.

    Rails kicks butt.

    In much the same way that the web took off because of “View Source”, Rails is taking off because it lowers the barrier to entry and holds nothing back.

    Having learned html and css by viewing the source, I can say that rails works much the same. I love open source, and it makes doing things for a kid with little programming experience like myself a piece of cake.

    x180 / james duncan davidson: Rails a Few Weeks On

    Now, on to Rails. Rails is the most well thought-out web development framework I’ve ever used. And that’s in a decade of doing web applications for a living. I’ve built my own frameworks, helped develop the Servlet API, and have created more than a few web servers from scratch. Nobody has done it like this before.

    So rails, starting to get hot, huh?

    RedHanded • Hopscotching Arrays with Flip-Flops

    Here is some real computer code. Explained:

    John Wilder: the double-dot is a flip-flop operator when used in a conditional. The flip-flop is turned on by the first expression’s truth and turned off by the second expression’s truth. The tricky thing about the flip-flop is that it keeps the on/off state inside, so once it’s turned on by the opening expression, it says on until the closing expression is proven true. why the lucky stiff

    Mike Clark's Weblog

    Learning ruby through testing it feature by feature – nice idea. Not only do you have a quick reference of everything you’ve ever learned, but if something in the library changes, you’ll know about it quickly.

    We have no idea if Ruby did what it should have done: we just know what it did. That is, we used the language as a tool to explore itself. In the same way that a test is better than a specification, the language is better than a description of the language. The test is definitive—when we ask Ruby what the answer to ‘Hello! ’ * 3 is, we’re going to the horse’s mouth. It doesn’t matter what the documentation says; what we’re testing is what actually happens. And that’s learning. So the test is both a learning test and a regression test.
