近期，不知道咋回事，垃圾评论铺天盖地，根本没时间审核，找到了一种方法，可以关闭多少天以前的评论，现记录在此供大家学习使用

修改主题模板文件 functons.php ，加入一个新function

function close_comments( $posts ) {
if ( !is_single() ) { return $posts; }
if ( time() - strtotime( $posts[0]->post_date_gmt ) > ( 30 * 24 * 60 * 60 ) ) {
$posts[0]->comment_status = 'closed';
$posts[0]->ping_status    = 'closed';
}
return $posts;

}

add_filter( 'the_posts', 'close_comments' );

以上30的单位是天，可以按需修改。

——-新版本的wordpress已经带超时评论关闭功能了，在设置里的讨论选项里，大家可以发掘一下

使用firefox、safari、chrome等浏览器打开谷歌主页，并键入“let it snow”进行搜索，谷歌在给出相关搜索结果的同时，页面会慢慢飘起雪花。随着雪花越积越多，电脑屏幕会逐渐模糊，并出现霜冻效果。这时，移动鼠标就能在结霜的屏幕上随便涂鸦。如果，你想摆脱屏幕被“冻”住的局面，只要点击一旁的“除霜”按钮，屏幕就会恢复清晰，此时尽管屏幕依然“下雪”，但霜冻效果不再，页面可正常使用。

手持GPS可以记录路线，出路书给其他驴友，不过价格不菲，好的都需要1000多大米，没关系，现在是智能手机时代，我的手机系统是安卓的，可以下载GPS2GE，记录路线，生成KML文件，直接导进GOOGLE EARTH,生成路书，并可以配上路上的图片，现在手机像素都很高了，手机拍相机拍都可以。
