Avoiding Firefox 3.0 frequent prompts when behind the proxy

You are reading this blog because you are using Firefox 3.0 and you are behind the proxy which needs authentication and you are annoyed by the frequent prompts for the username password.

How to stop this?

1) Just type about:config in your address bar

2) Enter network.auth.use-sspi in the filter field

3) Change the value to false if set to true

You will never be prompted anymore (may be you have to enter for the first time after making this change)

How to compute distance between two places

After successful implementation of my previous project I started working on my new project which is confidential :-)

I was trying to figure out if i could compute distance between 2 places which is one of the requirements for my project. After searching for about 4-5 hrs, I got what i want although not very precise.

Basically, you need the latitude and longitude of the places for which you need the distance. Thanks to the Yahoo Maps - GeoCoding API. You just need to provide the necessary details (like the location/city/country) and you get the latitude and longitude of the location.
In order to compute the distance you can use Haversine formula. Here is the java implementation.
It provides the result in nautical miles....

1 nautical mile = 1.85200 kms

I tried calculating distance between some of the places in chennai, India and it worked great.
