Final Exam, last question

The last question of the CS155 final exam was “What’s your favorite editor? Why?” Here are the answers:

Some of my favorite reasons “Why?”:

• pico, cause it starts with the letter “p”, of course!
• pico because I said so
• pico, because I am using a mac (different keyboard)
• vim because it is like word
• vi—I like a challenge
• emacs; I know how to save & exit
• notepad; because I am a masochist
• Blue! Because it’s the color of my water
• I don’t have a favorite editor because I really dislike Unix and just want to go back to using windows!
• See you next semester!

Change to Extra Credit

I’ve change the ruler part of the Extra Credit assignment. It no longer refers the environment variable $COLUMNS. If you did the assignment using $COLUMNS, that’s fine.

Problem with hw3.tgz

There was a problem with the file ~cs155/pub/hw3.tgz. I fixed it at 5:58PM Friday.

Lab Hours

The Computer Lab at the north end of the 3rd floor, USC, is open (when classes are in session):

• Mon-Thu 8:00AM–midnight
• Fri 8:00AM–6:00PM
• Sat 1:00PM–6:00PM
• Sun 1:00PM–midnight

Error in textbook

The textbook is wrong—there is no -r option to rmdir. You probably want rm -r to remove a directory and everything in it.

SSH download problem

There was a problem with the link to SSH. Get it here: http://www.cs.colostate.edu/~cs155/SSHClient-3.2.0.exe

hw1_prog

I fixed the problem with hw1_prog (part of HW1) being a 64-bit executable.

HW0 due date

I screwed up, and gave HW0 an early due date. I’ve fixed it—you can now turn it in whenever you like. Of course, it’s just practice, and never really due, but do it!
