Web Operating Systems

The following is a list of the most great webOS style system.Enjoy!

* Eye OS

eyeOS was thought as a new definition of Operating System, where everything inside it can be accessed from everywhere in a Network, using a web browser. eyeOS does provide a solid and stable platform to develop new applications to fit every company and school needs.

However, there's long list of these Os's coming up on the way and also many new ones are coming up.

Google Maps API used to map multiple locations.

Hi,

I was recently working on a project where i need to fetch multiple locations used google maps API. I searched a lot and tried many examples but was'nt able to find any appropriate, finally i gone through the documentation of google maps API. I found the solution

Below is the list where i stored all my addresses


var addresses =new Array();

addresses[] = '';



Here's my onload function


function load() {
      if (GBrowserIsCompatible()) {
        map = new GMap2(document.getElementById("map_canvas"));
        map.setCenter(new GLatLng(10, -180), 13);
        map.addControl(new GLargeMapControl());
        map.addControl(new GMapTypeControl());

        geocoder = new GClientGeocoder();
      
        GEvent.addListener(map, 'click', function(overlay, point) {
     if (point) {
       //document.getElementById("show_x").innerHTML = point.x;
       // document.getElementById("show_y").innerHTML = point.y;
     }
   });
  
   GEvent.addListener(map, 'zoomend',
                       function(oldZoomLevel, newZoomLevel) {
     //document.getElementById("zoom_old").innerHTML = oldZoomLevel;
     //document.getElementById("zoom_new").innerHTML = newZoomLevel;
   });
  
     }

showAddress();
    }

Here's my show address function


 function showAddress() {
       //alert("address : " + addresses);
     convertToLatLng();
    }

Here's my convertToLatLng, this function is the core function i used for


 var points = [];
    function convertToLatLng() {
      if (points.length >= addresses.length) {
        showPoints();
      } else {
        geocode(addresses[points.length]);
      }
    }

My geocode function


 function geocode(address) {
//alert(address);
   geocoder.getLatLng(
          address,
          function(point) {
          
           if(!point)
           {
          
           }
           else
           {
              points.push(point);
              window.setTimeout(convertToLatLng, 300);
              map.setCenter(point, 13);
             //var marker = new GMarker(point);
             var letters=["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P", "Q","R","S","T","U","V","W","X","Y","Z"];
            
             var marker=createMarker(point, letters[points.length-1]);

              map.addOverlay(marker);
              //marker.openInfoWindowHtml(address + "
Long: " + point.x + "
Lati:  " + point.y);
              //document.getElementById("show_x").innerHTML = point.x;
        //document.getElementById("show_y").innerHTML = point.y;
        //document.getElementById("zoom_new").innerHTML = 14;
            }
          }
        );
    }

My show points function, this function displays points for each location fetched from the database


function showPoints() {
      for (i in points) {
        var lat_lng = points[i];
        if (lat_lng) {
          var marker=createMarker(points[i], letters[i]);
 map.addOverlay(marker);
          //map.addOverlay(new GMarker(lat_lng));
        }
      }
    }

I tweaked a bit and created alphabetical markers for the map as below


     function createMarker(point, letter) {
    // use a custom icon with letter A - Z


var letter = letter;
var myIcon = new GIcon(G_DEFAULT_ICON, "http://www.google.com/mapfiles/marker" + letter + ".png");
myIcon.printImage = "http://maps.google.com/mapfiles/marker"+letter+"ie.gif";
myIcon.mozPrintImage = "http://maps.google.com/mapfiles/marker"+letter+"ff.gif";
var CallSign = CallSign;
var marker = new GMarker(point, {icon:myIcon});
//GEvent.addListener(marker, "click", function()
//{
//
//// save the info we need to use later for the side_bar
//gmarkers.push(marker)
//// add a line to the side_bar html
//
//
//
//});
return marker;
}

This is how i did to display multiple locations on the map.

Cheers!!!

Array List Sorting Issue

Hi,

Recently, i was coding for an application and came across a problem where i need to sort an ArrayList in an alphabetical order. However, that sounded quite easy as because sorting can easy with single arraylist. But, i was in a situation where i had two different ArrayLists with multiple attributes. So, what i did is that i kept a delimeter to distinct all my 3 values and then i added them into a temporary list.

for(int j=0;j

{

myBean=(MyBean)myList.get(j);

tempList.add(myBean.getOne() + "*" + myBean.getTwo() + "*" + myBean.getThree());

} 

then i used collection's sort method to sort them up in an alphabetical form.

Collections.sort(tempList,new MyComparator());  

I used inner class called Mycomparator to compare.

 class MyComparator implements Comparator {   

         

         public int compare(Object o1,   

                            Object o2) {   

            String s1 = o1.toString().toUpperCase();   

            String s2 = o2.toString().toUpperCase();   

    

            int counter = 0;   

    

            for (counter=0;counter

                               !Character.isDigit(s1.charAt(counter));counter++);   

    

            String temp1 = s1.substring(counter);   

    

            s1 = s1.substring(0,counter);   

    

            for (counter=0;counter

                           !Character.isDigit(s2.charAt(counter));counter++);   

    

            String temp2 = s2.substring(counter);   

    

            s2 = s2.substring(0,counter);   

    

            int max = (temp1.length() > temp2.length()) ? temp1.length() : temp2.length();   

    

            char[] pad = new char[max-temp1.length()];   

    

            Arrays.fill(pad,(char)48);   

    

            temp1 = String.valueOf(pad) + temp1;   

    

            pad = new char[max-temp2.length()];   

    

            Arrays.fill(pad,(char)48);   

    

            temp2 = String.valueOf(pad) + temp2;   

    

            s1 = s1 + temp1;   

            s2 = s2 + temp2;   

    

            return(s1.compareTo(s2));   

         }   

    

         public boolean equals(Object o1,   

                               Object o2) {   

            String s1 = o1.toString();   

            String s2 = o2.toString();   

    

            return(s1.equals(s2));   

         }   

    

      }   

And finally,. the problem got resolved, i got my list ordered in alphabetical form.

Problems installing Myeclipse 8.0

Well, later on i discovered that pulse explorer that is a part of my eclipse tried to download some updated from internet, since my machine was under a firewall it failed and showed abover errors. So, then as a solution for that, i downloaded and installed pulse explorer seperately and then ran my myeclipse setup again and this time, i got it successfully installed.
