screen with further instructions. Print that out to turn in along with
the answers to the following questions: …”
Assignment feedback
General:
• Missing assignment numbers
• Missing staples when multiple page assignments
• Type your name or print it big letters (why not type it)?
• Handwritten answers
Assignment 1:
• Confusion over memory vs storage and ROM vs RAM
• Skipped answers to questions
• Food for thought: what program were you executing while you
completed the survey?
Assignment 3:
• Skipped answer to question
Quizzes
• Collectively, you know all the answers.
• Use the quiz blog or other means of collaborating.
• Do not be satisfied with memorizing answers – it is
not worth the time and effort it takes.
Week 4
A couple of people accidently did too many
assignments -- how did that happen?
Asking questions is hard
• what program were you executing while you
completed the survey?
• What is the difference between memory and storage?
Assignment feedback
1. Several people did not turn in their Google Docs home
page with their post description – read carefully.
2. Confusion on program execution – go over example.
3. Is the movie industry long tail? Explain.
4. iPad I/O devices – any sensors?
Presentation/transcript confusion – use presentations
Groups:
How did you organize your work?
No first drafts!
The answer to the following question was not in the
presentation:
What is the cost trend for memory, storage and CPU chips?
How did you answer it?
Google docs versus word
• Which is best?
• Which does the future favor?

Assignment feedback
Client
Server
The survey, results and
program are all at
Surveygizmo in the
storage of their server.
I feel if I ask a question it will be dumb or embarrassing.
Now let’s see.....How many sentences will get me full credit for
this particular assignment?....... All joking aside, I identified
with what Michael Wesch presented. Much like the opening
remark above, I find that when I begin a course, I look to the
syllabus and associated schedule to determine what needs to
be accomplished over the semester to, get the “A”.
Last week I read “A student’s evaluation of Stanford’s massive
online courses,” on our class blog. That particular article made
me realize that there is a different type of student out there,
which is the student who demands to be challenged and who
does not want everything spelled out for him.

Collaboration
Smooth -- continuous
Click-click-click -- discrete
Would we get a better approximation if we sampled every
minute.
Would we get a better approximation if we could measure to
the nearest 1/100 degree.
One bit per pixel
Would a finer sampling grid yield a better
picture with more information?
Higher resolution -- more information?
Explain your answer in common sense terms.
Digital information
More samples → more information
More sample variety → more information
More information → better fit to reality
