Today is already thrusday. My first assignment is due tomorrow and I've only completed ONE question. For the rest, either I do not know how to do or I got an answer that is in correct. I'll try to see what I can do with it in 2 days. While I was trying to complete the assignment, I try to get a CD from boxup, initially I can't download with wget. So I gave up and used xuxule instead, but yesterday I tried to use curl instead of wget and it works! back to assignment. Mr BLOG
