I browse Hacker News from my iPhone, and due to the text size and link placements, I frequently mis-click, hitting user profile lnks instead of the story links. On other sites, this is fine, as I have time to hit stop and tap ok the correct link. Not so on HN - the profile page loads before I realize I've made a mistake.
So please, throw some for(i=0;i<10000;i++) loops in there. My productivity depends on it.
A user once complained that a job was running too long. After some research, I found something like this (SLEEP 10 seconds) inside a loop. I removed it. The batch time went from 7 hours down to 23 minutes. The user thought I was a genius. When I told my client (the IT manager) what I had done, he was pissed. He said, "You should have changed it to a SLEEP 5, so we had something to give him the next time he complained."
