Harvard College's CS50, the school's Introduction to Computer Science course for undergrads, has attracted about 1 in 8 students this fall -- a new record for the school and yet another sign of just how hot this field is becoming for the job-hungry.

The news, first reported by the Harvard Crimson, is based on stats released Wednesday by the Faculty of Arts and Sciences Registrar’s Office.

Overall, 818 undergrads (or 12% of the student body) signed up for the challenging course this semester, and nearly 900 students are registered when factoring in graduate and cross-registered students. Topics included in the syllabus include Linux, cryptography, HTML and JavaScript. David Malan, a Harvard CompSci grad, teaches the course.

CS50 has been around for 30 years and has attracted more students than any any other course in the past 5 years at Harvard, according to the Crimson. Principles of Economics is #2.

Rising interest in CompSci courses has been documented as well by the Computer Research Association, which earlier this year reported a 22% increase in enrollment for computer science bachelor’s degree programs at U.S. schools in 2013 vs. the year before.
