• Textbooks - required - strongly suggest to get a real book, you will find useful in your computing career:
  • Computer Systems: A Programmer's Perspective, 3/E (CS:APP3e), Randal E. Bryant and David R. O'Hallaron, Pearson (July 6, 2015), ISBN-13: 978-0134123837, ISBN-10: 0134123832.
    See http://csapp.cs.cmu.edu/3e/home.html for lecture notes.
  • The C Programming Language, Kernighan and Ritchie, Prentice Hall, 2nd ed., ISBN: 978-0131103627, and a Bash book of your choice.
• Platform: Linux and C. You need access to a Linux box for this course. Either use the school's Linux boxes or install a virtual machine with Fedora/Ubuntu/Debian or a choice of your own Linux distro. It's best if you get your machine multibooted along with your native OS such as windows or mac.
• Grading:
  • Weekly homework and programming assignments (20%)
  • Test 1 (20%), Thur, 2/21/2019, for an hour and 15 mins, the same classroom
  • Test 2 (20%), Thur, 4/4/2019, for an hour and 15 mins, the same classroom
  • Final exam (40%) - See the registrar's page for date, time and location.
• Homework:
  • Submit your homework at moodle: http://moodle.njit.edu
  • Homework is due at 11:59 pm of the posted due date.
  • Homework will not be accepted after the due date. Submit on time. Do not ask for exceptions. If you ask for an exception, I will apply that to everyone in class.
  • Exam questions are based on homework/programming assignments. Do your homework from scratch and on your own. Be prepared to spend an hour or two a day on homework.
  • Homework must be your own work. Do not show your code and/or copy other's code.
  • Copying homework will be referred to the University for disciplinary actions.
• NJIT policy on recording class materials: You may not record anything in class in any form with any device. You may not put any video/audio recorded class materials on the Web/Internet. You are breaking the policy.
• Social network-related: I do not join social network. Requests to join will not be answered. Once your info is out, it will be out there forever. You will never be able to take it back. Do it at your own risk. Read the Time magazine article "I helped create this mess. Here's how to fix it," published 1/28/2019.
• Exam related. Read carefully:
  • Exam papers will not be returned to you. The exam papers are kept for accreditation purposes. You may come and view your graded exam paper in my office during the office hours.
  • Procedure for exams: An hour or two before the exam, you will receive an email regarding seating assignment based on NJIT ID number. Make sure to take a seat according to the seating assignment. Numbered exams will be distributed to matching seats. Make sure your numbered exam paper matches your seat assignment. Leave your NJIT ID card on the table. IDs will be checked during the exam. Do not take someone else's exam paper. You both are taking someone else's exam.
  • Disagreement with exam marking/scores: If you disagree with your exam scores/marks, you may dispute within a week of receiving/seeing the graded exam paper. After a week, no exams will be contested.
  • Grading dispute: If you disagree with your grade, you may contest after the first school day but within a week of the following semester. After a week of the first school day of the following semester, no grading dispute will be considered.
  • NJIT policy on missed exams: There will be no make-up exam(s). You must plan your semester accordingly. Should you miss the exam(s) due to emergency, (a) go to the Dean of students, (b) explain your situation as to why you had to miss, and (c) ask to issue a memo to me. If and when I receive a memo from the Dean on your missed exam, I will copy your next exam score to the missing one. Those who miss the final exam will fail in the course unless you demonstrate a true emergency again through the office of the Dean of students. No other policy will be applied. Do not ask for an exception. No exceptions will be made.
  • The sample midterm and final exams sent out last semester(s) will be out there somewhere. Check the Web for the sample exams. Sample exams are for your reference only. Actual exams can be similar or completely different. Do not rely on the sample exams for your exam preparation.
• Email Policy: I read email and respond between 9 am to 5 pm, Monday through Friday.
  • I have no smart phone, hence no means to read and respond on-the-go.
  • I will try to respond within 24 hours. In most cases, I respond sooner than 24 hours. However, often times there are situations where I may not be able to respond to your email within 24 hours due to travelling, health, inclement weather, etc, in which case your patience is appreciated.
  • I appreciate emails that are concise, short, to the point. You don't need to write profuse pleasantaries, thanking in anticipation of my replies, finding your programming bugs, etc. while I understand you want to be courteous. Emails of half to a page containing programming questions, in particular assemblies, will take sometime even days for me to respond as I have to read carefully and actually execute to make sure you get useful comments from me. There are over 140 students enrolled in class. If 10% of the class send me emails with assembly programming questions regularly, it's not realistic for me to answer these questions in a timely manner, that is, within hours to a day. Keep it short and concise, to the point. I will answer as soon as I can but not within hours as I have no smart phone to read and respond on-the-go. You are encouraged to send questions to the three TAs.
  • Note that you'll get no response if you ask questions that are answered on this page, such as office hours, locations, TA names, their hours, exam dates and locations, the URL of lecture notes, etc.
• You are required to read the NJIT Policy on Academic Integrity for this course: https://www.njit.edu/policies/sites/policies/files/academic-integrity-code.pdf
