The third quiz has be posted. The Quizzes are not optional; see the Course Outline. You need to do each quiz at least five times.
Check the due date for each assignment and put a reminder in your agenda, calendar, and digital assistant. Just like in the Real World, not all due dates are on the same days or at the same times.

, personal web siteWorksheets are preparation for your assignments. You can’t do the assignments without having done the worksheets first, and you can’t do the worksheets without having first read the Course Notes:
Make notes from the worksheets on how each command works. What do the options used in the worksheets mean, for each command? (See the weekly List of Commands.)
Form a small study group to do the worksheets. Each person tries the example given, and you make sure you all get the same answers. Worksheets are not for hand-in; they are not worth marks; the assignments test your knowledge of the lectures and worksheets.
The worksheets are available in four formats: Open Office (ODT), PDF, HTML, and Text. Only the Open Office format allows you “fill in the blanks” in the worksheet. The PDF format looks good but doesn’t allow you to type into the blanks in the worksheet. The HTML format is crude but useful for quick for viewing online.
Do NOT open the Worksheet ODT files using any Microsoft products; they will mangle the format and mis-number the questions. Use the free Libre Office or Open Office programs to open these ODT documents. On campus, you can get a copy here: Course Introduction: Install Libre Office.

Worksheets prepare you for the upcoming assignments.
This course had two midterm tests (10%, 15%) and will have one final exam (40%).
Follow this link to see all your upcoming Quizzes and Tests. The dates are also posted on the Course Home Page and on Brightspace CST8207.
For full marks, read the Test Instructions (all the words) before your midterm tests.
Here are some statistics for the second midterm test:
86 students were registered in the course at the time of the midterm test. (We started the term with 95 students in mid-September.)
Of the 86, 7 did not write the test, leaving 79 who did.
Of the 79, 6 did not enter a valid test version code on the Scantron form. (I had to enter all those test version codes for you, so that you could get some marks.)
Of the 79, 6 did not enter their own name to match the name on file on ACSIS with the Algonquin Registrar office. (These students didn’t check their names using the Name Game before the test.)
Of the 79, 5 did not enter their own student number correctly.
Of the 79, 3 did not enter their own name or their own student number correctly, so the test couldn’t be marked. (I had to fix your test for you so that you could get some marks.)
Of the 79, 7 did not put their full name on their question sheet. I had to fix those names for you, so that you could get your question sheets back for the bonus assignment.
Of the 79, 36 answered question #45 even though the Test Instructions printed at the start of the test told you to leave the question blank (no answer).

Take notes in class! Keep a pad open on your desk.
Look at the Practice Tests and Answers related to the Final Exam. You can bring your questions to your lab periods and your instructor will go over them with you.
Check your EMail, especially when creating CRON jobs. One student had generated over 2,600 email messages (one per minute) using a CRON job that failed. (I deleted the job.)
Don’t forget to finish your five Brightspace quiz attempts for each of the Midterm 1 and Midterm 2 quizzes. There is a third quiz available to prepare for the Final Exam. Do at least five attempts in all three quizzes.
Nobody should have any files larger than 1MB in their CLS account.
If you have uploaded an image that is larger than 1MB, you should
make it smaller using the convert

Regarding world-writable files in your account: See last week’s notes.
Students who give answers (e.g. command lines) to other students are helping those other students fail my course. Stop doing that. I want everyone to pass my course.
Keep a notebook with a List of Commands in it.
- You need to write down yourself what each command does.
- Check the updated list of commands each week.
- I will check for this list in your lab periods.
- Bring your notes to class! Stop wasting time looking up commands.

Many students find that hiring a personal tutor helps them get through the first term. Financial assistance is available. See the Tutoring heading in the Course Introduction.
You are not paranoid if they really are out to get you! See the Week 03 Notes HTML for command pipelines to count the ongoing attacks on the CLS.
