Clock synchronization...

 

Wikipedia says practical limit is 200us with ntp over lan. And 10ms over Internet.

Precision time protocol is supposed to improve on this.. (also over lan)

Now this is funny:

This is implemented in Java, a language I have been told by people who get heavily voted up on this site is a ball and chain.

BigTable is implemented in C++ or Java. Cassandra appears to be most or all Java. But Java and other compiled languages are death for startups and corporations. Error! Error! Does not compute! Why aren't they using Ruby or Lisp?
