有次做项目的时候跟一个美国人通过MSN讨论一个问题。突然他说了一句,“Can you ping me in 15 minutes?” Ping Me，什么意思啊？
首先我们来看看“Ping”的原意：
Originally from the naval warfare practice of "active sonar" where
one ship (usually a surface ship) will send out a given sound or "ping"
in order to measure the direction and delay in the "echo" of that sound
off of another body usually a submarine. （海军使用的一种声纳来测量距离时使用的“声音”）
而现在的用法则是“send an email or other electronic message to someone”,也就是“电我，或者是短信我”。
This new usage has lasting power and is commonly heard everyday in high-tech companies.
最后我们来看看这个短语怎么使用呢：
Can we go to the movie tomorrow?
I don't know... Ping me around eight and we'll see how things are going.
