I had 40-50 apps installed on the phone. While the clean start was nice, reinstalling the “essential” apps and setting up their on-line accounts was a hassle. It took about 2-3 hours to restore the phone to where I had what I needed. In all, I now have 36 apps. Of these, I think I should pare down some more. It would be nice to get below 30. I’m still figuring out what I really need (like WordPlayer) and keeping a few that aren’t essential but really nice (like Pandora.) Some of the productivity items I seldom use an go, like GDocs. I’ve taken out many of the streaming apps like TV.com and Stitcher. But having a much lighter and reliable phone will be nice.

class Runner > ActiveRecord::Base
  belongs_to :stage
end

At first glance, I figure I would simply order on the stage number:

def self.find_all_runners
  find ( :all, :order => "stage.number" )
end

But this resulted in a “no such column” error:

SQLite3::SQLException: no such column: stages.number: SELECT * FROM “runners” ORDER BY stages.number

I found the solution in Ryan Daigle’s blog. In order for this to work you need a :joins to the linked table so Active Record knows the origin of stage.number. In my application, the find should be:

def self.find_all_runners
  find ( :all, :joins => :stage, :order => "stages.number" )
end

It looks like Apple might be making moves to loosen up their restrictions, if only ever so slightly. Earlier this week, Apple finally let a live video broadcasting app through the gates, after apps of that genre sat on the review backburner for months. Today, they’ve willingly approved another application that calls upon one of Apple’s private (and generally blacklisted) APIs.

I downloaded it an hour ago and had a chance to briefly use it. It gives me access to all of the books I’ve already purchased. I don’t see my newspaper subscriptions, but I suspect that will come in a future release.

The interface more book-like than the Stanza Reader. Where the Stanza reader uses touch regions to turn pages, on the Kindle reader, you use the page change gesture of sliding your finger from right to left across the screen as if you were flipping pages. Page changes are fast without the refresh flash you get on the Kindle device.

The iPhone is just about my mobile all-in-one device.
