Relearning/Modern C

Hi /prog/,
I want to re-learn C the right way.

When I was in college I took a bunch of courses (data structures, ADTs, algorithms) but I don't think I gained a deep knowledge of C.

What are some good books or resources on modern C usage (K&R is pretty dated)?

I'd like to do some HPC later in my life and I need to start somewhere.

Who is lol'd?

I've been penetrating this hacker sub-culture for a while now and maybe I can shed some light on this word.

LOL, or "laughing-out-loud", seems harmless. But in actuality it is used to identify other hackers in places where they are frowned upon. Many of today's youth has started to use LOL thinking it's the online version of "laughing", but they don't understand.

LOL is the the exact equivalent of a gang sign.

To differentiate between a user's harmless use of LOL and a symbol of "hackerdom", a lot of times there's the "'D" attached to the end. It becomes LOL'D. It comes from the last letter in the word "hacked".

Just like contractions use "'" to replace letters in common phrases (like "can't" uses the ' to replace the letters "no" in "cannot"), the whole phrase of LOL'D spelled out is "look out, line hacked".

It's a phrase dating back to when hackers used to mess with phone systems, they would say "look out, line hacked" so the other person wouldn't say anything incriminating -- they knew someone else was on the line with them. Now days, it's simply a common greeting.

Please, use this knowledge and don't throw LOL'D around because you don't know who you're attracting.
