This technique is quite similar to the ACI technique, with the exception that it doesn't rely on a bystander. The recipe is quite simple as well. When the programmer finds himself in complete darkness and has not the slightest idea of what is going wrong, he must print his code, leave his terminal and go to the cafeteria. After choosing his favorite drink, possibly with caffeine and sugar, he must read his code over and annotate it carefully. Understanding what a program does without actually running it is a valuable skill that a programmer must develop.
