Hide your wordpress source and feed from public

This works perfectly and visitors cant even tell what framework is used on my sites

remove_action('wp_head', 'wp_generator');

function disable_our_feeds() {
    wp_die( __('<strong>Error:</strong> No RSS Feed Available, Please visit our <a href="'. get_bloginfo('url') .'">homepage</a>.') );
}

add_action('do_feed', 'disable_our_feeds', 1);
add_action('do_feed_rdf', 'disable_our_feeds', 1);
add_action('do_feed_rss', 'disable_our_feeds', 1);
add_action('do_feed_rss2', 'disable_our_feeds', 1);
add_action('do_feed_atom', 'disable_our_feeds', 1);
