Notes
Lecture 15
----------
What happened with the midterm? Possibilities
- too long
- every question is worth 2 points, skip and come back
if one is taking too long!
- some of you tried pattern matching to assignments
rather than answering the question asked
- when faced with something you didn't know, you did a search rather
than think through what you already knew & what the question said
- you're doing the assignments by searching first rather than
thinking first
- not taking the time to understand tutorial/assignment code
beyond the bare minimum to answer assignment & tutorial questions
- they are short programs, you should understand every line
What's a special file?
- character devices, block devices, pipes, etc.
Why don't I give tutorial answers?
- because the journey is more important than the destination
- how you learned things is more important than what you learn
- again, doing searches for everything is the entirely wrong approach
- consult google for definitions, documentation, not answers
Tips for the final
- when you do the tutorials and assignments, do a search online
only after looking at man pages and trying to figure it out in
other ways
- if anything seems unclear, ASK (forums, lecture, TA, office hours)
