I'd like to go into a graduate program for Computer Science, but I need to weigh my options very carefully. Is a Ph.D. a near-guarantee of a spot in a skunkworks type of job (MS Research and the like)? Is a MS just as good for this? How does the "letter of recommendation" requirement work if you haven't kept in touch with your professors?
