But it's an ever-changing target. One day a skill is hot and the next it's not.

Job site Dice.com just sent us a list of tech skills that are worth over $100,000 a year. And that's just salary -- a new job might also net you bonuses, stock options and the like.

Dice is a tech-specific job hunting site. It sifted through its database of over 83,000 job postings, plus conducted a salary survey with over 15,000 participants, to come up with this list. (It's salary survey also revealed a few other insights about today's tech job market.)

And you are going to be surprised, because the hottest skills are not always the latest, greatest new thing.
