Problem: You are all alone in a far away land and needed to wake up early the next day. The problem is, you forgot to bring any alarm clock. But, you brought a Linux-powered laptop computer with you. Say for example an Asus Eee PC.Solution: Most Linux distributions have Python installed out-of-the-box. All you need is this very simple Python alarm clock script:
import time
import os
not_executed = 1
while(not_executed):
dt = list(time.localtime())
hour = dt[3]
minute = dt[4]
if hour == 5 and minute == 45:
os.popen2("open /Users/jun/shout.mp3")
not_executed = 0
Happy Hacking! :)
