    &lt;%= Time.now.strftime(&quot;%m/%d/%Y&quot;) %&gt;

You could simply do (substitute in `Time` for `DateTime` if using straight Ruby -- i.e. no Rails):

    DateTime.now.strftime(&#39;%m/%d/%Y&#39;)

If you&#39;re using that format a lot, you might want to create a `date_time_formats` initializer in your `RAILS_ROOT/config/initializers` folder (assuming Rails 2), something like this:

    # File: date_time_formats.rb
    ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!(
      :human =&gt; &quot;%m/%d/%Y&quot;
    )

Which will then let you use the more friendly version of `DateTime.now.to_s(:human)` in your code.

I think you can use `.strftime`:

    t = Time.now()
    t.strftime(&quot;The date is %m/%d/%y&quot;)

This should give `&quot;The date is 09/09/10&quot;`. See &lt;a href=&quot;http://www.wetware.co.nz/blog/2009/07/rails-date-formats-strftime/&quot;&gt;here&lt;/a&gt; for a great list of the format codes for `.strftime`.

If you don&#39;t need the full year you could try 
`Time.now.strftime(&#39;%D&#39;)`

I have a VideoView that takes up the top half of the Activity in portrait orientation with the bottom half of the screen showing some images and text.  I am playing a rtsp video stream in the video view when the Activity starts.  I have attached a MediaController to the VideoView via the following code:

		MediaController controller = new MediaController(this);
		controller.setAnchorView(this.videoView);
		controller.setMediaPlayer(this.videoView);
		this.videoView.setMediaController(controller);

When I tap the VideoView to bring up the MediaController on the screen I expected the playback controls to appear overlaying the bottom area of the VideoView (the bottom of the MediaController even with the bottom of the VideoView).  Instead the MediaController pops up lower down on the screen, overlaying some of the graphics and text I have below the VideoView.  

Are there some additional steps I need to take to get the MediaController to appear where I want it to on the screen?

Our web app is rendered totally on the browser.&lt;br/&gt;The server only talks to the browser through JSON messaging.

As a result, we only need a single page for the app and mostly all the `&lt;a&gt;` tags do not have a real `href` pointing to other pages.

In my quest of removing unnecessary things I was wondering if I can get rid of the zillions of `void(0)` we have in our code, as they seem useless:

	&lt;a onclick=&quot;fn()&quot;&gt;Does not appear as a link, because there&#39;s no href&lt;/a&gt;
	&lt;a href=&quot;javascript:void(0)&quot; onclick=&quot;fn()&quot;&gt;fn is called&lt;/a&gt;
	&lt;a href=&quot;javascript:&quot; onclick=&quot;fn()&quot;&gt;fn is called too!&lt;/a&gt;


**Does anybody knows if using `href=&quot;javascript:&quot;` can cause a problem?**&lt;br/&gt;
It works even on IE7...

Please don&#39;t spend your valuable time to tell me inline javascript is bad, as this is generated by a template engine :)

I&#39;m using Rails3, ActiveRecord

Just wondering how can I chain the scopes with OR statements rather than AND.

e.g. 

    Person.where(:name =&gt; &quot;John&quot;).where(:lastname =&gt; &quot;Smith&quot;)

That normally returns:

    name = &#39;John&#39; AND lastname = &#39;Smith&#39;

but I&#39;d like: 

    `name = &#39;John&#39; OR lastname = &#39;Smith&#39;




How to chain scope queries with OR instead of AND?

Is there a way to catch all uncatched exceptions in a rails controller, like this:

&lt;pre&gt;&lt;code&gt;def delete
  schedule_id = params[:scheduleId]
  begin
    Schedules.delete(schedule_id)
  rescue ActiveRecord::RecordNotFound
    render :json =&gt; &quot;record not found&quot;
  rescue ActiveRecord::CatchAll
    #Only comes in here if nothing else catches the error
  end
  render :json =&gt; &quot;ok&quot;
end&lt;/code&gt;&lt;/pre&gt;

Thank you

I&#39;ve tried reading through various blog posts that attempt to explain alias_method_chain and the reasons to use it and not use it. In particular, I took heed to:

http://weblog.rubyonrails.org/2006/4/26/new-in-rails-module-alias_method_chain

and

http://yehudakatz.com/2009/03/06/alias_method_chain-in-models/

I still do not see any practical use for alias_method_chain. Would anyone be able to explain a few things.

1 - is it still used at all?  
2 - when would you use alias_method_chain and why?

I have created a new user account on my mac and I am trying to update to the current version of ruby on it (1.9.2) from the snow leopard default of 1.8.7. Can somebody point me to tutorial or explain the best method to update Ruby on my mac from 1.8 to 1.9.2? Thanks

When using an idiom such as:

    def func(*args)
      # some code
    end

What is the meaning of `*args`? Googling this specific question was pretty hard, and I couldn&#39;t find anything.

It seems all the arguments actually appear in `args[0]` so I find myself writing defensive code such as:

    my_var = args[0].delete(:var_name) if args[0]

But I&#39;m sure there&#39;s a better way I&#39;m missing out on.

The `time` module can be initialized using seconds since epoch:

    &gt;&gt;&gt; import time
    &gt;&gt;&gt; t1=time.gmtime(1284286794)
    &gt;&gt;&gt; t1
    time.struct_time(tm_year=2010, tm_mon=9, tm_mday=12, tm_hour=10, tm_min=19, 
                     tm_sec=54, tm_wday=6, tm_yday=255, tm_isdst=0)

Is there an elegant way to initialize a `datetime.datetime` object in the same way?

I have a problem. I am trying to convert some strings to date, and I don&#39;t know the format the date is arriving.

It might come as `yyyy.mm.dd hh:mm:ss` or `MM.dd.yy hh:mm:ss` and so on.

How can I convert these strings to Date?
I tried this:

    DateFormat formatter = new SimpleDateFormat(&quot;dd-MM-yyyy hh:mm:ss&quot;);
    Date d = (Date)formatter.parse(someDate);

But when I printed out someDate it printed out like this: 2010-08-05 12:42:48.638 CEST which means `yyyy.mm.dd hh:mm:ss`, however when I ran the above code, the date object now became `Sat Jan 31 00:42:48 CET 11` which is strange to say the least.

Any ideas how I can correctly format strings to date?

How to convert String to Date without knowing the format?

I have a date returned as part of a mySQL query in the form `2010-09-17`

I would like to set the variables $Date2 to $Date5 as follows:

`$Date2 = $Date + 1`

`$Date3 = $Date + 2`

etc..

so that it returns `2010-09-18`, `2010-09-19` etc...

I have tried 

    date(&#39;Y-m-d&#39;, strtotime($Date. &#39; + 1 day&#39;))

but this gives me the date BEFORE `$Date`.

What is the correct way to get my Dates in the format form &#39;Y-m-d&#39; so that they may be used in another query?
