+===== September 23, 2014 =====
+Please note that the lecture room for EECS4221A/CSE5421A has been changed to:
+Bethune College Room 230 (BC 230)
+===== October 6, 2014 =====
+Please note that the deadline for reserving a first topic to do a Topic Study is Wednesday October 8, 24:00 midnight.
+===== October 20, 2014 =====
+COSC4221 Test 1 will be held on Wednesday, October 22, 2014 19:00-21:00.
+Test 1 will include:
+a) Material covered in the lectures from the beginning of the term up to and including the lecture on Wednesday October 15;
+b) Material in the files OSD.1.pdf, OSD.1.1.pdf, OSD.2.pdf, OSD.3.pdf, slides 1 to slide 45 (up to VFS Inode Operations in Linux) in OSD.4.pdf, in the course directory;
+c) Material in Chapter 10, “File-System Interface” and Chapter 11, “File-System Implementation” of the book “Operating System Concepts”, 8th Ed; (Chapter 11, “File-System Interface” and Chapter 12, “File-System Implementation” of the book “Operating System Concepts”, 9th Ed);
+d) Material in Chapter 12 “The Virtual Filesystem” of the book “Understanding the Linux Kernel”, 3rd Edition related to the material in the slides listed in item b above.
+(Please make sure that you have the most up-to-date version of the slides in the above mentioned files, as some of the slides may have been updated since you last downloaded them.)
+It is possible that Test 1 may include true/false questions, questions that require short answers, questions that may require the drawing of diagrams, questions that require slightly longer answers, and other possible question formats.
+MAKE SURE YOU READ AND UNDERSTAND ALL THE MATERIAL IN THE SLIDES.
+ALSO NOTE THAT DRAWING THE SAME KIND OF DIAGRAMS AS ILLUSTRATED IN THE SLIDES, WILL BE AN IMPORTANT COMPONENT OF TEST 1. For example, if you are given a diagram similar to that on slide 9 of OSD4.pdf, “Example of a Small File System Tree in Unix”, then you should be able to draw the corresponding diagram on slide 10, “Internal Structure of Small File system Tree in Unix”, as well as the corresponding diagram on slide 24, “In Memory VFS Objects and On Disk Objects”.
+Also please note that, unfortunately, I am unable to provide individual answers to individual student questions regarding what kind of questions may be included, or not included, in the tests, beyond what I had said during the lectures and what has been posted on the course website above.
+The reason is because doing so will be unfair to other students in the class who do not receive the same information.
+For all questions regarding tests, please ask me during the lectures so that everyone in the class would have equal opportunity to know my answers to any questions regarding any test.
+Thank you for your understanding.
+===== October 29, 2014 =====
+Please note that each group that is not doing a programming assignment (groups that are doing a programming assignment do not need to do a second topic study) may select a second topic among topics that have not been reserved so far in the list of topics in the file /cs/course/4221/4221_topics, then send email to me to reserve the selected topic.
+Note that the reservation of topics is first-come-first-served, so it would be prudent to select a first and second choice in case another group had sent an email to reserve a same topic before the topic list could be updated.
+Please also note that for the second topic, you are not required to present the topic study in class. However, you are still required to submit hard copies to me and also electronically submit to the course directory /cs/course/4221/submit/topic copies of both the topic study presentation slides and topic study report. The second topic study and the project are due December 5, 2014, 24:00 midnight.
+===== November 17, 2014 =====
+Please note that EECS4221 Test 2 will be held on Wednesday December 3, 2014, 19:00, (not November 26).
+ Test 2 will include:
+(a) Material covered in the lectures, with emphasis on material covered in the lectures since Test 1 and up to and including the lecture on Wednesday November 26;
+(b) Material in the slides OSD.4, OSD.4.1.pdf, OSD.5.pdf, OSD.6.pdf in the course directory;
+(Although there are no books that cover all the material in the slides in OSD.5, however, reading Chapter 5, “Kernel Synchronization”, of the book, “Understanding the Linux Kernel”, 3rd Edition, may help understand some of the material on synchronization in the slides in OSD.5.pdf. Reading Chapter 1 to Chapter 3 of the book “MicroC/OS-II The Real-Time Kernel”, 2nd Edition, may help understand some of the material on μC/OS-II in the slides in OSD.6.pdf. Both books have been put on reserve for 2-hour loans at Steacie Library)
+It is possible that Test 2 may include true/false questions, questions that require short answers, questions that require calculations, questions that may require the drawing of diagrams, questions that require writing short programs using pseudo C code similar to that used in the slides, questions that require slightly longer answers, and other possible question formats.
+MAKE SURE YOU READ AND UNDERSTAND ALL THE MATERIAL IN THE SLIDES. PLEASE NOTE THAT ALTHOUGH THE EMPHASIS OF TEST 2 WILL BE ON MATERIAL THAT HAS NOT BEEN TESTED SO FAR, THE MATERIAL IN TEST 2 MAY STILL DEPEND ON KNOWLEDGE OF PREVIOUS MATERIAL.
+PLEASE MAKE SURE THAT YOU ARE USING THE MOST RECENT/UP-TO-DATE VERSION OF THE SLIDES/LECTURE-NOTES TO PREPARE FOR TEST 2, AS THE SLIDES/LECTURE-NOTES MAY HAVE BEEN MODIFIED TO IMPROVE CLARITY OR TO REMOVE ERRORS.
+ALSO NOTE THAT DRAWING THE SAME KIND OF DIAGRAMS AS ILLUSTRATED IN THE SLIDES, WILL BE AN IMPORTANT COMPONENT OF TEST 2.
+Please note that, as announced in class, for the assignment, topic studies and the project, both hard copies and electronic copies of the PowerPoint slides and reports must be submitted on or before Friday December 5, 24:00 midnight.
