Building Simple Shoutcast Web Interface for Mobile Part 1

by nolovelust 30. March 2010 21:15

UPDATE 14/01/2011  Shoutcast stopped providing public API for their dataabse. You need to register at http://dev.aol.com/SHOUTcast/ to get your API Key.

After that you can simply edit /App_Code/ScESettings.cs and replece settings with below ones.

 

public static string strURLsearch = "http://api.shoutcast.com/legacy/stationsearch?k=YOURAPIKEY&search=";
public static string strURLbrowse = "http://api.shoutcast.com/legacy/genresearch?k=YOURAPIKEY&genre=";

 

Before all here is the complete script shoutcast-mobile.zip (592.97 kb) and here is the working version at http://mobile.web.tr/shoutcast

This app designed for high-end mobile phones that are capable of doing AJAX requests

Now, lets start from Default.aspx

Newzbin.com Found Liable For Copyright Infringement

by nolovelust 29. March 2010 21:00

If you are watching piracy fight between downloaders and movie studios you've probably heard about MPAA vs Newzbin.

Today Royal Courts of Justice in London, United Kingdom concluded that  Newzbin.com is liable for copyright infringement.

This is sort of landmark ruling in U.K. as it puts USENET under fire of MPAA after Kazaa, E-donkey and Bittorent.
