• Underscore 1.4.0 and 1.4.1 helpfully blow up when passed nil. Underscore 1.4.2 is sane again.

URL helpers with Draper must be mocked under test. Any better solutions?

• Add a default host environment in the test setup?
• Try view tests?

ruby-debug w/ 1.9.3 and RubyMine 4.0.3 => dyld: symbol not found

• Use debugger gem

Other helps?

… No.

Interesting Things

• For testing – thin default logger (no one claimed this)
• debugger gem – use it! (see Helps)
• Use litmus to help debug how your emails look on multiple platforms (blog post forthcoming?)
• Don’t start a new rails project today (well, maybe if you use non-SSL rubygems). http://railsapps.github.com/openssl-certificate-verify-failed.html

Our first attempt:

<ScrollView
    android:layout_width=...
    android:layout_width=...
    >
    <View
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        />
</ScrollView>

Unfortunately there is a bug in Android where setting layout_gravity=”center” on a ScrollView’s child causes incorrect scrolling when you start hiding and showing other views in the layout (the ScrollView will get stuck with an offset such that you can’t completely scroll to the top, and you can scroll past the bottom).

Here’s the solution:

<ScrollView
    android:layout_width=...
    android:layout_width=...
    android:fillViewport="true"
    >
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        />
        <View
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            />
        <View
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            />
        <View
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            />
    </LinearLayout>
</ScrollView>

The wrap_content in the LinearLayout is a bit misleading: fillViewport=”true” in the ScrollView will cause its child to always be at least as large as the viewport. (See also Romain Guy’s article about fillViewport.)
