Past Announcements for Spring 2021

• (4/14) NJIT and Webex: weekend NJIT has announced that starting Friday 10pm (4/16) through late Sunday (4/18) Webex access might not be available and this would affect Webex Recordings. The expectation is that it won't affect Kaltura material that has been prerecorded.
• (4/5) Midterm Class Performance Guidance for midterm class performance based on 4 homeworks and 2 exams is available in section C.1.a of the course web-page (not canvas).
• (4/5) Exam 2 grading Grades for exam 2 have been posted in canvas. The exam would be visible in canvas later today. Solutions not visible in canvas will have a solution key posted in section C later this week.
• (4/1) Course Evaluation Sometime on late Tue (4/6) or early Wed (4/7) you will receive an email re the course evaluation. There will be an available session to complete the evaluation in advance from 11am through 5pm on Wed (4/7) (through canvas or the NJIT GO app). If you postpone doing it at that time frame, it can then only be done after Apr 12, 2021.
• (4/1) Exam 2 grading and Midterm class performance The intent is to complete the grading of Exam 2 by Monday morning (just like every other HW and Exam) and have a midterm class performance reported (through section C.1.a of the course web-page) also on Monday morning. The midterm class performance would provide an estimate of how you are doing in class so far: A range, B/B+ range, C/C+ range and D/F. In the remote case that Exam 2 grading would not be available, this midterm class performance would still be posted. But some fundamentals would not change 50% of points for a C or better.

• (3/30) Preparatory (second): Exam 2 A reminder about tomorrow Wed, March 31, 2021. The exam, Exam 2 will commence at 12:30pm (half past noon time). Between 11am through around 12:15pm I will complete Subject 7; the class through Webex from my NJIT OFFICE not from the classroom. The afternoon @NJIT hours will be held as scheduled. This exam will be graded by Sai, not the instructor. The instructor grades Exam 1 and Exam 3. Either later tonight or early tomorrow I will publicize the link to Exam2. Expect an automated email from my.njit.edu similar to the one you received at Exam 1 time. Moreover, the instructions for Exam 2 have already been posted in section C of the course web-page and are the same as those of Exam 1 and will remain the same with those of Exam 3 (final). Please do not email me/us and asking me/us whether the exam is open textbook: the answer is in the instructions and/or Document 2 (canvas Announcements) and it is a NO. Two things are ONLY allowed in the EXAM: pens and pencils is one of them, two sheets of scratch paper (pre-labeled per instructions) is the second.
• (3/26) HW4 grading Grading has been completed. Grades are available through canvas and HW4 would remain accessible for 14 days. A solution key, in addition to the visible correct answers in canvas, is available in Section C.
• (3/12) Preparatory: Exam 2 Exam 2 follows one week after the class that follows the break. Setup is going to be similar to that of Exam 1. Same instructions: for the record they are available in Section C.2. Material that will be examined is from Chapters 2, 3, 4, 9, and 10 of the designated textbook. They are mapped to Subjects 2, 3, 4, 5, and 6. Subject 2 coverage is material after multiprogramming but note that multitasking is multiprogramming and timesharing; in effect all of Subject 2 is needed!
• (3/8 ) HW3 grading I am going through canvas' auto grading by hand because there have been some discrepancies in canvas.
• (3/7 ) Availability of Webex recordings I was testing class WebexRecordings both from canvas and directly from Webex and it seems that recordings do not start and their viewing stalls. This might be a transient phenomenon or not. I have already sent an email to instruction@njit.edu. It might be possible that you can download the recording and then start it locally, if remote starting/watching does not work. This can be done if you click on the download icon next to the recording's name. I dont know how fast this will get resolved. But there are Kaltura voiceovers as well, plus the notes you might keep from class. Webex has been doing maintenance; read comment in canvas main page, before you head to a course.
• (3/3 ) HW3 typos There is time-slide somewhere in the text inolving timesharing. It should have been a time-slice. Furthermore for question 16, subquestion (1) asks what happens with the CPU. Not with I/O. A time-slice refers to the CPU.
• (2/21) Exam 1 grading Exam 1 has been graded. Grades are in canvas. The exam is open for inspection and will remain so for approximately two weeks. Statistics in section C of the course web-page. A solution key will be posted before next class also in section C.
• (2/15) Exam 1, practice exams and sample exams A past sample exam is available in section C.5. Note it is for a 'paper-based' exam and for a class that used to meet twice a week. An NJIT practice exam is available through a link of section C.0. You can access it directly from canvas orientation for students and without using the link. Read the info in C.0. Before the exam study also Document 2 (available in Canvas Announcements since before the start of the semester). The instructions for the exam (EXAM 1) have already been available (since Jan 29) under section C.2 of the course web-page. Exam material includes everything handed out in class/canvas (eg HW1, HW2, and canvas self asssessments) plus Subject 0, the discussion of the textbook related to Subject 1, and Subject 2 (slides 1-50).
• (2/15) HW2 grading HW2 has been graded. Grades in Canvas. It will be open for inspection for 14 days. Collect in the mean time any info needed. A Solution key in section C of the course web-page.
• (2/5) Keeping you busy: SA-1, HW2, SA-2 Practice with SA-1 (SelfAssessment 1) first for no course credit but just the practice. Then move to HW2 and Exam preparation. For more practice on caches, you have SA-2 (SelfAssessment 2).
• (2/2) Classroom It is CKB 217. (It changed into something else, but it has been reassigned to this class eventually.)
• (2/1) HW1 HW1 has been graded; grades are available in canvas. Moreover the HW has been released in canvas and it is viewable. It would be viewable for 14 days starting 2/1 and will stop being viewable on 2/15. A solution key is available in section C.
• (2/1),(1/29), (1/28), (1/27), (1/25), (1/22) Verification of Presence: Banner Students who completed the VoP have had their presence confirmed into Banner.
• (1/29) Webex Recordings All uptodate as of second week of classes in Canvas Modules.
• (1/27)Self-Assessment 1 It is available in Canvas. Covers material we will be doing in class on 1/27.
• (1/29), (1/28), (1/27), (1/25), (1/22) Verification of Presence: Banner Students who completed the VoP have had their presence confirmed into Banner.
• (1/19) Self-Assessment 0, Homework (HW) 1 Self-Assessment 0 is available as Canvas Classic Quiz. It is not for course credit (even if canvas has assigned points to it). You may do it or you may skip it. Some of the questions appear as review or self-assessment questions in Subject 0 (pdf slides in Section C of the course web-page and also in their original form in Canvas/Modules / Subject0). Homework 1 (HW1) has been published in canvas as a Canvas Classic Quiz worth 30pt. HW are due before noon of a Thursday, which is not a class day. You have 3 opportunities to submit (including canvas autosubmit for you), but only the last one (recent one) will be graded!
• (1/19) VoP (Verification Of Presence) The verification of Presence (VoP) is setup as a Canvas Classic Quiz. It will be available at 12:30pm on the first day of classes (this is half an hour past noon time). It will be available through and before noon of the second Sunday of the semester. Before you do it follow the instructions. It is a timed (60mn) quiz with 2 questions based on Document 0, Handout 1 (Syllabus), and Section B of the course web-page.
• (1/19) Assistant's hours The Assistant's (TA, grader) hours have been finalized and are available under Course Information. Moreover, Webex meeting info is available for him in section C.0 of the course web-page but not in Canvas Announcements.
• (1/14) Room Change ? Although this is not going to affect classroom delivery for the first two weeks of classes, apparently the room for the course has changed. I'll wait for the second class to see if things change further.
• (1/13) Accessibility issues fixed (I think) Accessibility issues related to section B have been fixed. They had to do with access control list permissions beyond my initial control.
