Adding another line `--ignore-dir=save.d` did the trick

I&#39;m trying to work out if it&#39;s possible to use percentage positions/sizes when creating a layout. What I want is something like this...

    ^
    |
    |
    | 68%
    |
    |
    v
    Gallery (height equivalent of 16% total screen size)
    ^
    | 16%
    v

I&#39;m testing on a device which in landscape has a display of 800x480 actual pixels and I&#39;m currently forcing it with the following...

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;RelativeLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;fill_parent&quot; &gt; 
        &lt;Gallery 
            android:id=&quot;@+id/gallery&quot;
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;80px&quot;
            android:layout_marginTop =&quot;320px&quot;
        /&gt;
    &lt;/RelativeLayout&gt;

Obviously I don&#39;t want to hard-code fixed `px` units but I can&#39;t use `68%` or `0.68` for `layout_marginTop` (for example). I&#39;ve looked at `dp` units but I&#39;m not sure if I can do it that way either.

I have to admit UI design is a weak point of mine so any advice would be gratefully received.

**EDIT:** For future reference if anyone is looking for a similar answer, following Alan Moore&#39;s suggestion I have the following working exactly how I want it...

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:orientation=&quot;vertical&quot;
        android:background=&quot;@drawable/bground&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;fill_parent&quot; &gt;
        &lt;TextView
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;0dp&quot;
            android:layout_weight=&quot;0.68&quot;
            android:background=&quot;@android:color/transparent&quot;
        /&gt;
        &lt;Gallery 
            android:id=&quot;@+id/gallery&quot;
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:layout_weight=&quot;0.16&quot;
        /&gt;
        &lt;TextView
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;0dp&quot;
            android:layout_weight=&quot;0.16&quot; 
            android:background=&quot;@android:color/transparent&quot;
        /&gt;
    &lt;/LinearLayout&gt;

I managed to find some other examples of using `layout_weight` and decided to set the `TextView` heights to `0dp` and also used floats for the weights. Working great. :)

Set position / size of UI element as percentage of screen size

I installed pip on Windows by downloading http://pypi.python.org/packages/source/p/pip/pip-1.0.2.tar.gz#md5=47ec6ff3f6d962696fe08d4c8264ad49 and running `python setup.py install`

Installation went fine with no errors.

But when I tried installing selenium package with it, it gives me the following error -

    pip install -U selenium
    Unknown option: u
    Unknown or unsupported command &#39;install&#39;

Where I&#39;m making the mistake?

pip on Windows giving the error - Unknown or unsupported command &#39;install&#39;

I&#39;m not sure what it&#39;s for, but the code I&#39;m working on has a bunch of folders called &quot;save.d,&quot; it looks like they&#39;re used for some sort of version control (we also have .svn folders).

How can I update my .ackrc file to ignore those directories by default?

My .ackrc is currently

    --type-set=inc=.inc
    --ignore-dir=pear
    --type-set=tpl=.tpl

Our folder structure can look like:

    program/parsers/save.d
    program/modules/save.d



Ignoring a directory using ack&#39;s .ackrc

I'm not sure what it's for, but the code I'm working on has a bunch of folders called "save.d," it looks like they're used for some sort of version control (we also have .svn folders).
How can I update my .ackrc file to ignore those directories by default?
My .ackrc is currently
<pre><code class="hljs language-ini">--type-set=inc=.inc
--ignore-dir=pear

With the normal `grep` command there is an `--exclude` option (covered in detail here: https://stackoverflow.com/questions/221921/grep-exclude-include-syntax-do-not-grep-through-certain-files) that lets you ignore specific files when you are grepping.

Ack&#39;s `--type` option takes care of 95% of the cases where you&#39;d want to exclude files, but it doesn&#39;t (as far as I can tell) handle the case of excluding a specific file.  I&#39;ve got a compiled JS file that has the contents of every other JS file in it (on a single line), so every time I grep for *anything* I get back the entire contents of that giant compiled file.

I&#39;d hate to have to give up on ack and go back to grep over this, but it is *really* annoying.  Please, someone tell me there&#39;s a way to exclude specific files from ack searches.
