The function you are looking for is `eq`, which is a member of [AnyRef][1]:

    val x = new Obj
    val y = x
    x eq y // evaluates to true
    x ne y // evaluates to false

I&#39;m experiencing a minor issue with fonts in my stylesheet.

This is my CSS:

    body
    {
      ...
      font: normal 62.5% &quot;Lucida Sans Unicode&quot;,sans-serif;
    }

    #wrapper_page
    {
      ...
      font-size: 1.2em;
    }

    input, select, textarea
    {
      ...
      font: bold 100% &quot;Lucida Sans Unicode&quot;,sans-serif;
    }

And this is the result:

![browser password fields][1]


  [1]: http://i.stack.imgur.com/SAa0Q.png

I think there is an internal css setting, somewhere, on webkits  that modify the shape of the password dots. How can I get rid of it and have the same style on every browser?

Thanks!

EDIT: I just found something curious: by default, webkit browsers apply this CSS to password fields:

    input[type=&quot;password&quot;]
    {
      -webkit-text-security: disc;
    }

And that&#39;s what is replacing the classic middot.
I tried setting it to circle or none, but I cannot get something similar to what is shown by other browsers.

EDIT: I FOUND A SOLUTION.
If you are using &quot;Lucida Sans Unicode&quot; font for your website, that&#39;s the problem! The only font that emulate correctly the password field&#39;s big dots of other browsers is Verdana, mixed with a little bit of letter spacing. So, for both Opera and Webkit, use the following code to fix it: 

    .opera input[type=&quot;password&quot;],
    .webkit input[type=&quot;password&quot;]
    {
      font: large Verdana,sans-serif;
      letter-spacing: 1px;
     }

What is the best way in Python to determine what values in two ranges overlap?

For example:

    x = range(1,10)
    y = range(8,20)

    (The answer I am looking for would be the integers 8 and 9.)
            
Given a range, x, what is the best way to iterate through another range, y and output all values that are shared by both ranges? Thanks in advance for the help.


**EDIT:**

As a follow-up, I realized that I also need to know if x does or does not overlap y. I am looking for a way to iterate through a list of ranges and and do a number of additional things with range that overlap. Is there a simple True/False statement to accomplish this?

How do you test reference equality in Scala?

    val x = new Obj
    val y = x
    x.referenceEquals(y) // evaluates to true

For reading files in Scala, there is 

    Source.fromFile(&quot;file.txt&quot;).mkString

Is there an equivalent and concise way to write a string to file?

Most languages support something like that. My favorite is Groovy:

    def f = new File(&quot;file.txt&quot;)
    // Read
    def s = f.text
    // Write
    f.text = &quot;file contents&quot;

I&#39;d like to use the code for programs ranging from a single line to a short page of code. Having to use your own library doesn&#39;t make sense here. I expect a modern language to let me write something to a file conveniently. 

There are posts similar to this, but they don&#39;t answer my exact question or are focused on older Scala versions.

For example:

* https://stackoverflow.com/questions/4604237/how-to-write-to-a-file-in-scala


Scala: write string to file in one statement

&gt; _In mathematics and computer science, a tuple is an ordered list of elements. In set theory, an (ordered) n-tuple is a sequence (or ordered list) of n elements, where n is a positive integer._

So, for example, in Python the 2nd item of a tuple would be accessed via `t[1]`.

In Scala, access is only possible via strange names `t._2`.

So the question is, why can&#39;t I access data in tuples as Sequence or List if it is by definition? Is there some sort of idea or just yet not inspected?

Why is Scala&#39;s syntax for tuples so unusual?

I frequently find myself working with Lists, Seqs, and Iterators of Tuples and would like to do something like the following,

    val arrayOfTuples = List((1, &quot;Two&quot;), (3, &quot;Four&quot;))
    arrayOfTuples.map { (e1: Int, e2: String) =&gt; e1.toString + e2 }

However, the compiler never seems to agree with this syntax.  Instead, I end up writing,

    arrayOfTuples.map { 
        t =&gt; 
        val e1 = t._1
        val e2 = t._2
        e1.toString + e2 
    }

Which is just silly.  How can I get around this?

Tuple Unpacking in Map Operations

In Scala I can enforce type equality at compile time. For example:

    case class Foo[A,B]( a: A, b: B )( implicit ev: A =:= B )

    scala&gt; Foo( 1, 2 )
    res3: Foo[Int,Int] = Foo(1,2)
 
    scala&gt; Foo( 1, &quot;2&quot; )
    &lt;console&gt;:10: error: Cannot prove that Int =:= java.lang.String.

Is there a way to enforce that type A and type B should be different ?



Enforce type difference

It seems that `Vector` was late to the Scala collections party, and all the influential blog posts had already left.

In Java `ArrayList` is the default collection - I might use `LinkedList` but only when I&#39;ve thought through an algorithm and care enough to optimise. In Scala should I be using `Vector` as my default `Seq`, or trying to work out when `List` is actually more appropriate?
