Input: I'm a little bit confused with the following phrase. I was reading an article about concurrency in Java and there was a sentence saying: It is worth noting that both unlockRead() and unlockWrite() calls notifyAll() rather than notify(). This phrase seemed quite strange to me. What does it mean?.
Output:
'It is worth noting that' simply means 'here's something, which you should remember:' or 'here's something you should pay attention to:' or 'here's something that is worth reading and remembering:' It's that simple. Regarding (1), there is no connection at all to 'apropos' or 'besides...' Regarding (2), it always means exactly the same thing. It simply means 'Here's an interesting point:' (There is utterly no connection in any way to 'useless' or 'costs nothing'.) It is worth noting that, the ELL site exists for basic questions about the meanings of phrases.
