Как будет "чайник" в смысле новичок, неумеха по-английски?

Contrary to the belief of many, a noob/n00b and a newbie/newb are not the same thing. Newbs
are those who are new to some task* and are very beginner at it,
possibly a little overconfident about it, but they are willing to learn
and fix their errors to move out of that stage. n00bs,
on the other hand, know little and have no will to learn any more. They
expect people to do the work for them and then expect to get praised
about it, and make up a unique species of their own. It is the latter we
will study in this guide so that the reader is prepared to encounter
them in the wild if needed.
