A better method is [`CGI.unescape`][1]:  
*URI.unescape is deprecated*



    decoded_uri = CGI.unescape(encoded_uri)


  [1]: https://ruby-doc.org/stdlib-2.5.1/libdoc/cgi/rdoc/CGI/Util.html#method-i-unescape

Via `decode`:

    require &#39;uri&#39;
    URI.decode(encoded_uri)

Ruby `2.7` and above:

 
    require &#39;uri&#39;
    URI.decode_www_form_component(encoded_uri)

The equivalent of PHP&#39;s `urldecode` in Ruby is `CGI::unescape`.

Well the thing with `=3f` and `=3d` is quoted-printable encoding. Ruby can decode it with the `.unpack(&quot;M&quot;)` method.

The backslashes? They&#39;re just weird and wrong. It would probably be safe to string-replace them to `/` since backslash should not be in a URL to begin with.


The developer documentation has seemed to have failed me here.  I can create a static widget without thinking, I can even create a widget like the analogue clock widget that will update itself, however, I can not for the life of me figure out how to create a widget that reacts to when a user clicks on it.  Here is the best code sample that the developer documentation gives to what a widget activity should contain (the only other hint being the API demos, which only creates a static widget):

    public class ExampleAppWidgetProvider extends AppWidgetProvider {
        public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
            final int N = appWidgetIds.length;

            // Perform this loop procedure for each App Widget that belongs to this provider
            for (int i=0; i&lt;N; i++) {
                int appWidgetId = appWidgetIds[i];

                // Create an Intent to launch ExampleActivity
                Intent intent = new Intent(context, ExampleActivity.class);
                PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

                // Get the layout for the App Widget and attach an on-click listener to the button
                RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout);
                views.setOnClickPendingIntent(R.id.button, pendingIntent);

                // Tell the AppWidgetManager to perform an update on the current App Widget
                appWidgetManager.updateAppWidget(appWidgetId, views);
            }
        }
    }

from: [The Android Developer Documentation&#39;s Widget Page][1]

So, it looks like pending intent is called when the widget is clicked, which is based off of an intent (I&#39;m not quite sure what the difference between an intent and a pending intent is), and the intent is for the ExampleActivity class.  So I made my sample activity class a simple activity that when created, would create a mediaplayer object, and start it (it wouldn&#39;t ever release the object, so it would eventually crash, here is it&#39;s code:

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.sound);
		mp.start();
	}

However, when I added the widget to the home screen, and clicked on it, nothing played, in fact, nothing played when I set the update timer to just a few hundred milliseconds (in the appwidget provider xml file).  Furthermore, I set break points and found out that not only was it never reaching the activity, but no break points I set would ever get triggered.  (I still haven&#39;t figured out why that is), however, logcat seemed to indicate that the activity class file was being run.

So, is there anything I can do to get an appwidget to respond to a click?  As the `onClickPendingIntent()` method is the closest I have found to a `onClick` type of method.

I am unable to find examples where xlwt is used to write into existing files. I have a existing xls file that I need to write to. When I use xlrd to read the file, I cant seem to figure out how to transform the &quot;Book&quot; type returned into a xlwt.Workbook. I would appreciate if someone can point me to an example.

I understand that it is a replacement for ActiveRecord and that it uses objects instead of queries. 

But...
 
why is this better? 

will objects/queries be &quot;easier&quot; to create?

will it lead to more efficient SQL queries?

will it be compatible with all major DBs? - I assume it will.

will it be easier/harder to use with stored procedures?

I am wondering what is a convenient function in Rails to convert a string with a negative sign into a number. e.g. `-1005.32`

When I use the `.to_f` method, the number becomes `1005` with the negative sign and decimal part being ignored.
