Funny, knowledgeable, a bit condescending, and doesn't just repeat previous years' homework. However, beware OS security. Had to learn re-learn assembly with 3 weeks left. It is THE HARDEST UNIT and he saves it until the end and had over half the endterm on it. Also participation is a bit subjective. HW5 was a blast tho.","source_url":"https://www.ratemyprofessors.com/professor/2580912","quality_rating":3.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:42:05.685776+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM0NTExNjIx","source_instructor_id":"rmp:2580912","instructor_name":"Earlence Fernandes","course_label":"CS642","course_id":"COMPSCI 642","course_uid":"course_a76e77747c5b78e3b42f681c","review_date":"2021-04-06 15:02:47 +0000 UTC","comment":"I was so excited to take this class (Information Security), but Earlence Fernandes is just NOT a good teacher. He'll spend 10 minute wasting time on something irrelevant, and speed through confusing material. Hard to keep up, and overall not a good speaker. Approximately 100 "uhms" and "ahs" per minute, making it very hard to pay attention.","source_url":"https://www.ratemyprofessors.com/professor/2580912","quality_rating":1.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:42:05.685776+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTMzNjgzMTUx","source_instructor_id":"rmp:2580912","instructor_name":"Earlence Fernandes","course_label":"CS642","course_id":"COMPSCI 642","course_uid":"course_a76e77747c5b78e3b42f681c","review_date":"2020-10-07 01:41:39 +0000 UTC","comment":"Earlence by far exceeded expectations in every aspect: lectures that you didn't mind listening to, enjoyable / valuable homework, and great jokes. By FAR my favorite professor I ever had in UW Madison CS. Took this course during the beginning of COVID so we were 75% in person and 25% online.
