Swine flue cases in Sweden 2009 (click for larger image)

The results are interesting to say the least. From this simple test it seems that in this particular instance AdSense relies entirely on the filename / URL alone to determine content targeting. If the file is called world_of_warcraft_guide.htm, then ads about World or Warcraft would show, regardless of page title and page content (see images below).

Furthermore, if the filename was buy_car_online.htm, then ads about car rental would display, despite the title being DVD-player (in swedish) and the content being about DVD players.

See for yourselves.

Further, the security benefits from masked passwords are likely minimal for most users and applications. However, there are situations and applications that legitimately benefits from masked password fields, and to cover all bases that best solution might be to enable the user to decide wether masking is warranted or not.

This can be achieved with a simple javascript toggle function:

function switchType(obj){
if(obj.getAttribute('type')=='text')
{
obj.setAttribute('type','password');
}else{
obj.setAttribute('type','text');
}
obj.focus();
}

This function is then called when the user checks a checkbox:
<input onclick="switchType(document.form1.password);" type="checkbox" />

“Common sources of location information include Global Positioning System (GPS) and location inferred from network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs”

This functionality was earlier available through 3rd part solutions such as Google Gears, but now it is natively supported in Firefox.

The key function is: navigator.geolocation.getCurrentPosition()
If you have Firefox 3.5+ you may test the Geolocation API here (please let me know if the result is correct).

I also make use of the API in my geographical chat/game Zapin (in Swedish, but have a look).

Here is the javascript that makes it happen:
var oRequest = new XMLHttpRequest();
var sURL = "geodecode.php?lat="+position.coords.latitude+"&lon="+position.coords.longitude;

oRequest.open("GET",sURL,false);
oRequest.setRequestHeader("User-Agent",navigator.userAgent);
oRequest.send(null)

var MyAdress = 'Time:' + position.timestamp + '<br>Latitude:' + position.coords.latitude + '<br>Longitude:' + position.coords.longitude + '<br>Accuracy:' + position.coords.accuracy + 'm<br>Altitude:' + position.coords.altitude + oRequest.responseText;
document.getElementById('adressField').innerHTML = MyAdress;
}

if (navigator.geolocation) {
// Geo request
navigator.geolocation.getCurrentPosition(GeoDecode);
}

The trick is to add a listener when creating the markers, and then use getElementID to select the corresponding item in the document, identified by a uniqe ID.

(Java script)
var marker = new GMarker(point, customIcons[\"standard\"]);
GEvent.addListener(marker, \"mouseover\", function() {
marker.setImage(\"../images/marker_h.png\");
var listItem = document.getElementById(\"item-\" + j);
listItem.style.backgroundColor = \"#FFFA5E\";
});
GEvent.addListener(marker, \"mouseout\", function() {
marker.setImage(\"../images/marker.png\");
var listItem = document.getElementById(\"item-\" + j);
listItem.style.backgroundColor = \"#FFFFFF\";
});

The HTML could for example look like this:

<li id="item-1">Some content</li>

Maybe not the most elegant solution, but it does the job.

Finally, some useful resources for Google map developers:
Google Maps API Tutorial by Mike Williams
Simple to use tool to make custom markers

a:not([href*="mydomain"]) {

 padding-right: 10px;

 background: transparent url("images/aoutside.gif") center right no-repeat;



}

Alternatively, you can use this one to mark all links that start with ‘http://‘

a[href^="http"] {

padding-right: 10px;

background-image: url(external.gif);

background-position: right !important;

background-repeat: no-repeat;

}

After some hours of searching on Google however, I came across this solution.

1. Click the Start button in the lower left corner.

2. Right click Internet Explorer and select “Run as Administrator”

3. Accept the warning dialog

4. Now as IE is in administrator mode,  go to http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp and run the upgrade.

This worked for me.

Good luck.

• Go to the GMaps plugin configuration page (in Options) and enter your API key (and select default Zoom level).
• In your header.php template file, change <body> to <body onload="load()" onunload="GUnload()">.
• Make a new post.
• Add at least the City and Country custom keys, and add the tag [ GMaps ] (without extra spaces) where you want the map to render.
• Done!

Plugin output

1.  First we need to create a full text index for the fields we want to search (note that fields have to be of TEXT or VARCHAR type). This is done by

ALTER table1 ADD FULLTEXT (’column1′,’column2′,’…’)

2. The search query could then look like this:

SELECT *, MATCH(`column1`,`column2`) AGAINST (’$phrase’) AS relevancy

FROM table 1

WHERE  MATCH(`column1`,`column2`) AGAINST (’$phrase’)

and the result like this:

 data1   data2  data3  0.9454332

where the tailing number would be the score, or relevancy that can be used to rank search results. This is very handy and a lot more user-friendly than the rigid WHERE LIKE construct.
