I&#39;m having trouble representing a mobile number in one of my applications.

I was wondering if there is an Integer class that will allow you to store such a number starting with 0417254482. Perhaps using a string be a more appropriate?
At present when I&#39;m trying to use represent a phone number with ints, doubles longs I seem to store random numbers and not the numbers I meant to store.

What&#39;s the right way to represent phone numbers?

I need to extend the Networkx python package and add a few methods to the `Graph` class for my particular need

The way I thought about doing this is simplying deriving a new class say `NewGraph`, and adding the required methods.

However there are several other functions in networkx which create and return `Graph` objects (e.g. generate a random graph).  I now need to turn these `Graph` objects into `NewGraph` objects so that I can use my new methods.

What is the best way of doing this?  Or should I be tackling the problem in a completely different manner?

I&#39;m aware of the `pdftk.exe` utility that can indicate which fonts are used by a PDF, and wether they are embedded or not.

Now the problem: given I had PDF files with embedded fonts -- how can I extract those fonts in a way that they are re-usable as regular font files? Are there (preferably free) tools which can do that? Also: can this be done programmatically with, say, iText?

Is there a way to change a _Tkinter_ widget&#39;s font style without knowing the widget&#39;s font family and font size?

Use case: We create our UI using standard _Tkinter_ widgets (_Label_, _Entry_, _Text_, etc). While our application runs we may want to dynamically change the font style of these widgets to bold and/or italics using the `.config()` method. Unfortunately there appears to be no way to specify a font spec without specifying the font&#39;s family and size.

The following are examples of what we&#39;d like to do, but neither of these examples work:

    widget.config(font=&#39;bold&#39;)

or
    
    widget.config(font=( None, None, &#39;bold&#39; ))

How much data can be added in java.util.List in Java at the maximum?

Is there any default size of an ArrayList?

How much data can a List can hold at the maximum?

I can&#39;t seem to find a definitive answer on this and I want to make sure I understand this to the &quot;n&#39;th level&quot;  :-)

&lt;pre&gt;

    a = { &quot;a&quot; =&gt; &quot;Hello&quot;, &quot;b&quot; =&gt; &quot;World&quot; }
    a.count  # 2
    a.size   # 2
    a.length # 2
    
    a = [ 10, 20 ]
    a.count  # 2
    a.size   # 2
    a.length # 2

&lt;/pre&gt;

So which to use?  If I want to know if a has more than one element then it doesn&#39;t seem to matter but I want to make sure I understand the real difference.  This applies to arrays too.  I get the same results.

Also, I realize that count/size/length have different meanings with ActiveRecord.  I&#39;m mostly interested in pure Ruby (1.92) right now but if anyone wants to chime in on the difference AR makes that would be appreciated as well.

Thanks!


Count, size, length...too many choices in Ruby?

I read in multiple places that the default buffer size for a pipe is 4kB (for instance, [here][1]), and my `ulimit -a` tends to confirm that statement:

   

    $ ulimit -a
    core file size          (blocks, -c) 0
    data seg size           (kbytes, -d) unlimited
    scheduling priority             (-e) 0
    file size               (blocks, -f) unlimited
    pending signals                 (-i) 15923
    max locked memory       (kbytes, -l) 64
    max memory size         (kbytes, -m) unlimited
    open files                      (-n) 1024
    pipe size            (512 bytes, -p) 8 // 8 * 512B = 4kB
    POSIX message queues     (bytes, -q) 819200
    real-time priority              (-r) 0
    stack size              (kbytes, -s) 10240
    cpu time               (seconds, -t) unlimited
    max user processes              (-u) 1024
    virtual memory          (kbytes, -v) unlimited
    file locks                      (-x) unlimited

But when I use a little program to test the buffer size (by writing into the pipe until the write() blocks), I see a limit of 64kB!

See this program:

    #include &lt;stdio.h&gt;
    #include &lt;unistd.h&gt;
    #include &lt;limits.h&gt;
    
    int main(void)
    {
    	int tube[2];
    	char c = &#39;c&#39;;
    	int i;
    
    	fprintf(stdout, &quot;Tube Creation\n&quot;);
    	fprintf(stdout, &quot;Theoretical max size: %d\n&quot;, PIPE_BUF);
    	if( pipe(tube) != 0)
    	{
    		perror(&quot;pipe&quot;);
    		_exit(1);
    	}
    	fprintf(stdout, &quot;Writing in pipe\n&quot;);
    	for(i=0;; i++)
    	{
    		fprintf(stdout, &quot;%d bytes written\n&quot;, i+1);
    		if( write(tube[1], &amp;c, 1) != 1)
    		{
    			perror(&quot;Write&quot;);
    			_exit(1);
    		}
    	}
    	return 0;
    }

And its output:

    $ ./test_buf_pipe 
    Tube Creation
    Theoretical max size: 4096
    Writing in pipe
    1 bytes written
    2 bytes written
    3 bytes written
    4 bytes written
    [...]
    65535 bytes written
    [blocks here]

It strongly suggests that the pipe buffer size is actually 64k!
What is happening here??

Is it possible to set width or height of HTML element (ex. `&lt;div&gt;`) in JavaScript in Standards Mode?

Note the following code:

    &lt;html&gt;
    &lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot;&gt;
        function changeWidth(){
            var e1 = document.getElementById(&quot;e1&quot;);
            e1.style.width = 400;
        } 
    &lt;/script&gt;
    &lt;body&gt;
        &lt;input type=&quot;button&quot; value=&quot;change width&quot; onclick=&quot;changeWidth()&quot;/&gt;
        &lt;div id=&quot;e1&quot; style=&quot;width:20px;height:20px; background-color:#096&quot;&gt;&lt;/div&gt;
    &lt;/body&gt;
    &lt;/html&gt;

When user presses the _change width_ button, the `&lt;div&gt;`&#39;s width should change.

It works fine when doctype declaration determines Quirks Mode. In Standards Mode I&#39;m unable to change the element&#39;s size this way

Is it possible to manipulate the size of an element in Standards Mode? How to bypass this disfunctionality?

I&#39;m a migrating Eclipse IDE user and am learning my way round IntelliJ IDEA 9.

By default Eclipse IDE won&#39;t use a starred import until you import 99 classes from the same package, so it practically never happens.

But IntelliJ IDEA seems only too keen to do it, and I can&#39;t work out how to disable it.

For example, after typing `JList` then &lt;kbd&gt;ALT&lt;/kbd&gt; + &lt;kbd&gt;ENTER&lt;/kbd&gt; to auto-import, the whole `javax.swing` package is imported instead of just the class I specify.

I tried excluding `javax.swing` from the auto-completion, but that just stops _any_ Swing classes from being suggested, which is counter-productive.

I have read https://stackoverflow.com/questions/302122/jquery-event-keypress-which-key-was-pressed and https://stackoverflow.com/questions/2445613/how-can-i-check-if-key-is-pressed-during-click-event-with-jquery

However my question is if you can get the same key event for all browsers? Currently I know that Firefox gives the &lt;kbd&gt;command&lt;/kbd&gt; button (Mac) the code 224 while Chrome and Safari give it the value 91. Is the best approach to simply check what browser the user is using and base the key pressed on that or is there a way so that I can get 1 key code across all browsers? 
Note I am getting the value with the:

    var code = (evt.keyCode ? evt.keyCode : evt.which);
I would love to not use a plugin if possible just because I only need to know about the &lt;kbd&gt;command&lt;/kbd&gt;/&lt;kbd&gt;ctrl&lt;/kbd&gt; (windows system) key pressed.

Vim is my preferred text editor when I program, and thus I always run into a particularly annoying issue. 

Frequently, when I quickly need to save the buffer and continue on to some other miscellaneous task, I do the typical

    :w

However, I always&#160;— what seems to be like more than 50% of the time&#160;— manage to capitalize that&#160;`:w`. Naturally, Vim yells at me because `W` is an invalid command:
    
    E492: Not an editor command: W

My question is how can one **alias colon-commands in Vim**. Particularly, could you exemplify how to alias `W` to `w`.

I am aware of the process to *map keys* to certain *commands*, but that is not what I’m looking for.

If so, what is the shortcut key to achieving this?

I have a `TextView` that I&#39;m dynamically adding text to.

in my `main.xml` file I have the properties set to make my max lines 19 and scrollbars vertical.

in the `.java` file I am using `textview.setMovementMethod(new ScrollingMovementMethod());` to allow for scrolling.

The scrolling works great.  As soon as 19 lines are taken up, and more lines are added it starts scrolling just as it should.  The problem is, I want the new text to scroll into view.

I am writing out the value for `textview.getScrollY()` and it stays at `0` no matter what (even if I manually scroll it down and add a new line of text).

consequently `textview.scrollTo(0, textview.getScrollY());` does nothing for me.

Is there another method I should be using to obtain the vertical scroll amount for the `textview`?  Everything I&#39;ve read says that for all intents and purposes, what I&#39;m doing should be working :/

Using jQuery, I would like to disable scrolling of the body:

My idea is to:

1. Set `body{ overflow: hidden;}`  
2. Capture the current `scrollTop();/scrollLeft()`  
3. Bind to the body scroll event, set scrollTop/scrollLeft to the captured value.

Is there a better way?

Update:

Please see my example, and a reason why, at http://jsbin.com/ikuma4/2/edit

I am aware someone will be thinking &quot;why does he not just use `position: fixed` on the panel?&quot;.

Please do not suggest this as I have other reasons.

Any ideas?

Event when user stops scrolling

I&#39;m making a pagination system (sort of like Facebook) where the content loads when the user scrolls to the bottom. I imagine the best way to do that is to find when the user is at the bottom of the page and run an Ajax query to load more posts.

The only problem is I don&#39;t know how to check if the user has scrolled to the bottom of the page. Any ideas?

I&#39;m using jQuery, so feel free to provide answers that use it.
