解决wlw写日志不能发布图片
昨天写东西的时候遇到了使用windows live writer写日志,插入图片后,不能发布,说日志页面不支持图片发布。 自己之前用的是emlog,最近才升级到WordPress 3.0,就出现了这个问题。搜索了一下,别人也出现过这个问题,但大多数是因为换了主机,要修改media里面的上传目录的相对路径,改成wp-content/uploads。但是我这个就没有用了,因为自己没有换主机什么的,修改了之后同样不能上传。 根据wlw的提示,弄了下ftp方式上传,貌似速度比较慢,还试了下flickr upload插件,我觉得挺好,不过每一次使用,都会出现一个windows错误,不知道怎么回事,但忽略之,还是能用的。 好了不说闲话,为了解决这个问题,我在WordPress后台上传了一张图片,果然也出现了错误: “large_gizd_1877l200065.jpg” has failed to upload due to an error Unable to create directory /home/vhosts/laofish.6te.net/wp-content/uploads/2010/10. Is its parent directory writable by the server? 发现这个错误之后,我就意识到是自己上传目录的权限不够,因为开始装上WordPress3.0之后,我的目录里面没有uploads文件夹,是我自己创建的,检查发现其权限是755,修改成777之后,后台上床没有问题了,在用windows live writer尝试,同样也成功了。
Excel小技巧
先记一个数组公式的输入方法:先选择好一系列结果要出现的单元格,然后输入公式,最后按ctrl+shift+enter就可以把公式输入进去了。 还有一个excel的画图技巧,在一张图里面同时绘制折线图和柱状图。 其实说起来很简单,在图的数据区域右击,选择数据区域添加数据,注意水平轴标签不要动它。然后要改变的曲线上右击,设置数据系列格式,选择次坐标轴,然后就会出现一个新的坐标轴。这个时候,你右击曲线,更改图表类型,就可以了。 其实说起来步骤不多,但是如果没做过的话,改起来还是十分费劲的,比如上图右边那个坐标轴我都不知道怎么移到中间。
使用feed43烧录网站
教务处最新通知rss: http://www.feed43.com/ndjwc_tongzhi.xml 照教程做的好玩,详细了解http://www.feed43.com/ 注意那个item link指的是点击rss标题后跳转的网址,仍然不能挖掘里面的内容, 可能雅虎pipes可以,但是现在没精力去弄那个以前弄的也不是很成功,就此算了
