The day after the stranger from Woot departed once more, a new student approached Master Foo as he was pruning the plum trees.
“I have heard of your reputation,” the student said, bowing low. “They say you teach the Way of Unix, not for power, but for understanding. May I learn at your feet?”
Master Foo nodded. “What is it you seek?”
“I wish to master the system,” the student said, “to understand every process, every socket, every thread of the great Net. I seek elegance, not exploits.”
“You speak wisely,” said Master Foo. Then he scribbled an IP address on a small bamboo slip. “Crack this machine. Its defenses are trivial. Return and tell me what you learn.”
The student departed.
The next morning, he returned, his robes slightly rumpled but his eyes alight with triumph.
“Master,” he said, “the machine was a decoy for an abandoned cryptocurrency exchange node. I rewrote a dormant smart contract and siphoned off forgotten tokens. The wallet had a bug, my code fixed it. I now possess wealth beyond imagining.”
“You have reported this to the rightful owners?” asked Master Foo.
“There are none,” said the student. “The domain expired, the company dissolved, and the blockchain is immutable. I wrote no logs, touched no traceable endpoints, and masked every call behind a thousand proxies. I am free and unseen.”
“Then you are a thief,” said Master Foo.
“I am not caught,” replied the student. “What I took, no one missed. What I altered, no one saw. And what I gained, no one can take from me.”
Master Foo was silent for a time.
At last, he said, “The first student broke the law and found caution. You have broken nothing and found profit.”
He bowed low to the student.
“Here,” said Master Foo, “is the end of my teaching. Today, you have taught me.”
On hearing this, the student was puzzled.
But Master Foo was enlightened.
