Day 21 announcements

Hi all,

Nice work today (Day 21). As discussed, I have updated the slides for today with the clearer Therac-25 definition and extra visual aid that were shown in class.

11:00am section only: I was mistaken about the fate of Vitaly Kaloyev. In fact, he won an award from his regional employer. I apologize for the mistake.

Midterm complete!

Thank you all for the relatively smooth midterm experience! Grades have been posted. Here are some frequently asked questions:

Can I see what I got right and wrong?

Yes, with an office hours appointment. I know it’s annoying, but while you would never try to save completed tests or post answers online, some students feel the need to try. The nature of the test requires special vigilance over completed copies. As a result, students (rightfully) wondering what they got right and wrong will need to schedule an office hours appointment. The meeting should only take a few minutes.

I missed the midterm, can I take it now?

This is one of the few assignments in the course (along with projects and final papers) that are scheduled on certain days and do not qualify for late work. The relevant portions of the syllabus are below.

In preparation for the midterm…

From the midterm page! .

As mentioned on the syllabus, you can bring up to 30 pages of numbered unique handwritten notes to this exam. One physical page with two sides counts as one – that is, you can write on the back of each page and have it still count as one page.

Please number the pages of your handwritten notes in the top right corner.

Please limit the number of pages that you bring to class to 30. It is strongly encouraged, though not required, to minimize the time it takes for me to approve your notes by removing them from extraneous material, spirals, binders, etc. All typed material should also be removed from the papers you bring to class.

You can speed up the note-checking process before the exam by fanning out your notes for approval, like this:

Make sure all electronic devices are off or on silent during the test; they must be inside your backpack and not on the desk or in a pocket. Smart watches may not be worn during the test.
