/ All programmers are optimists. Perhaps  \

| end goal. Perhaps it is merely that     |
| computers are young, programmers are    |
| younger, and the young are always       |
| optimists. But however the selection    |
| process works, the result is            |
| indisputable: "This time it will surely |
| run," or "I just found the last bug."   |
