I just installed nginx and php fastcgi about an hour ago, and after reading examples of a quick starting configuration, and the nginx documentation etc, I just cant get it to work.

No matter what I change or try, I always only get the &quot;Welcome to Nginx!&quot; screen on &quot;localhost/...&quot; - I cant even call a simple index.html

My config:

(the stuff in the comments is what I tried out)

    // default nginx stuff (unchanged)
    
    server {
        #listen 80 default_server;
        #listen 80 default;
        listen 80;

        #server_name localhost;
        #server_name _;

        #access_log /var/log/nginx/board.access_log;
        #error_log /var/log/nginx/board.error_log;
        
        #root /var/www/board;
        #root /var/www/board/public/;
        root /var/www/board/public;

        #index index.html;
        index index.html index.htm index.php;
    }

If I understand it right, this should be the easiest setup, right? just define `listen 80;` and  `index index.html;` but I just cant get it to work

The file /var/www/board/public/index.html exists and has content

Before I waste 2 more hours trying out something, can someone of you give it a quick watch and tell me what I&#39;m doing wrong? Thanks.

correct configuration for nginx to localhost?

I have a form with a textbox on it that is used to enter a URL.  I need to add (http://) as a predefined value to this textbox and want it to be read only so the user won&#39;t be able to remove the http:// but he can write after it.

How to set the first few characters of a WinForms TextBox to Read-Only?

The icon that IntelliJ (v11.1) usually shows next to Java classes is a blue circle with a C. But for one of my classes this icon has a small &quot;x&quot; in the top left corner. This particular class is in a package with another class, which has just the usual C in a blue circle.

In case it matters, I&#39;m using a Mac.

The class in question is **AlertsHandler**.

I wanted code to convert all the characters in strings to uppercase or lowercase in Java.

I found a method that goes something like this:

    public static String changelowertoupper()
    {
             String str = &quot;CyBeRdRaGoN&quot;;
             str=str.toLowerCase(Locale.ENGLISH);
             return str;
    }
 
Now I&#39;ve read that using certain `Locale`s, like Turkish, &quot;returns ***i (without dot)*** instead of ***i (with dot)***.&quot;

Is it safe to use `Locale`s like UK, US, ENGLISH, etc.? Are there any big differences between them when applied to strings?

Which is the most preferred `Locale` for `String`s?

Using Locales with Java&#39;s toLowerCase() and toUpperCase()

I have this common issue, as it appears to be. My table view wont refresh my items after I reset them. I have checked the data and it&#39;s the new one. 

**I tried multiple solution from internet but no success.** 

Can&#39;t reset all the columns because it adds one empty one extra (dont know why) and the resize just breakes.

My table is not **editable**. The new data is changed.

The data is refreshed if I **change the ordering** of the items and the rows change (:|).

I&#39;m just left without ideas.

At the moment the refresh code is pretty simple.


    ObservableList&lt;User&gt; data = FXCollections.observableArrayList(User.getResellers());
    reseller_table.setItems(data);

Again the new data is correct. When I make an selection to the tableView it returns the new correct Item.

Is there any advantage to making methods to access private variables in your class instead of making the variable public?

For example is the second case better than the first?

    //Case 1
    public class Shoe{
        public int size;
    }
    
    //Case 2
    public class Shoe{
        private int size;
        public int getSize(){
            return size;
        }
    
        public void setSize(int sz){
            size = sz;
        }
    
    }

Advantage of set and get methods vs public variable

When I started to look for the benefits of polymorphism, I found with [this](https://stackoverflow.com/questions/11064409/why-to-use-polymorphism) question here. But here I was unable to find my answer. Let me tell what I want to find. Here I have some classes:

    class CoolingMachines{
    	public void startMachine(){
    		//No implementationion
    	}
    	public void stopMachine(){
    		//No implementationion
    	}
    }
    
    class Refrigerator extends CoolingMachines{
    	public void startMachine(){
    		System.out.println(&quot;Refrigerator Starts&quot;);
    	}
    	public void stopMachine(){
    		System.out.println(&quot;Refrigerator Stop&quot;);
    	}
    	public void trip(){
    		System.out.println(&quot;Refrigerator Trip&quot;);
    	}
    }
    
    class AirConditioner extends CoolingMachines{
    	public void startMachine(){
    		System.out.println(&quot;AC Starts&quot;);
    	}
    	public void stopMachine(){
    		System.out.println(&quot;AC Stop&quot;);
    	}
    }

    public class PolymorphismDemo {
    	CoolingMachines cm = new Refrigerator();
    	Refrigerator rf = new Refrigerator();
    }

Now here I created two objects in the Demo class and are references of `Refrigerator`. I have completely understood that from the `rf` object I am able to call the `trip()` method of `Refrigerator`, but that method will be hidden for the `cm` object. Now my question is why should I use polymorphism or why should I use

    CoolingMachines cm = new Refrigerator();

when I am OK with

    Refrigerator rf = new Refrigerator();

Is polymorphic object&#39;s efficiency is good or light in weight? What is the basic purpose and  difference between both of these objects? Is there any difference between `cm.start();` and `rf.start()`?

Is there an interface in Java similar to the `Callable` interface, that can accept an argument to its call method?

Like so:

    public interface MyCallable&lt;V&gt; {
      V call(String s) throws Exception;
    }

I would rather avoid creating a new type if there already exists something that I can use. Or is there a better strategy to having multiple clients implement and plug in a callable routine?

Is there an interface similar to Callable but with arguments?
