Q: Question: 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? 
Answer: "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.

A: yes

Q: Question: Someone told me that I shouldn't use the phrase discuss about, but should say, instead, discuss (the topic). He said discuss means talk about and using discuss about is like saying talk about about, which is redundant. Is he correct? Could somebody elaborate on this? 
Answer: Your friend is correct. You can discuss something, or you can talk about it, but discuss about is redundant for the reason you identified. discuss: to speak with another or others about But if you want to use the word about, you can have a conversation about, confer about, debate about, or even have a powwow about. Most of the other synonyms for discuss don't take about, nor is it needed to converse (or debate).

A: yes

Q: Question: I understand the capitalization rule for nouns, proper nouns require a capital letter. Also, I should begin a new sentence with a capital letter. When & why "mom/dad" requires a capital letter ? (Reference- ELL- I am at Vapi where mom is hospitalised) mom: (n) informal term for a mother/North American term for mum. 
Answer: When it is their name, Mom and Dad would be capitalised: Dear Mom and Dad, I am just writing to let you know, that although everyone has a mom and a >dad, you are my special mom and dad. So, Mom, I just want to say 'brava!'; and Dad, 'bravo!'. I've just been telling Sis, that Mom's new coat is so cool. XX Here's the commentary from an exercise from BBC English on Line ...to have a roast chicken lunch with my mother. I can't wait! - mother does not need a capital 'M' as it is not being used to replace her name. If I said, "I am going to lunch with Mum", it would need a capital letter, but "I am going to lunch with my mum" does not.

A:
yes
