什麼是Ping ? 什麼是 Trackback ?

wiki : ping

In blogging, ping is an XML-RPC-based push mechanism by which a weblog notifies a server that its content has been updated. An XML-RPC signal is sent to one or more "ping servers," which can then generate a list of blogs that have new material. Many blog authoring tools automatically ping one or more servers each time the blogger creates a new post or updates an old one.

總之就是通知某Server(像是個大BSP)，部落格有更新。

A trackback is one of three types of linkbacks, methods for Web authors to request notification when somebody links to one of their documents. This enables authors to keep track of who is linking, and so referring, to their articles.
