View source for Source Terminal Puzzle

[[File:Terminal_lightos.gif|center]]
The patterns in the flashing lights on the front of the [[Source Terminal]] are ASCII codes for "undelete". Entering this at the terminal unlocks six files (dot.txt, identity.txt, master.txt, normal.txt, square.txt and zero.txt) and two commands (cat and decrypt). cat lets you read the contents of the files, and decrypt shows you different contents with the correct key.

Translation: With the mapping butt -> 0, buttt -> 1 and butttt -> 2, each line is a ternary number. Converting these to ASCII yields "Clever, buttt a waste of time."

The decryption key for this file is 'matrix'. This can follow any of the words making up the text files to make a phrase ([[Wikipedia:Dot matrix|dot matrix]], [[Wikipedia:identity matrix|identity matrix]], [[Wikipedia:normal matrix|normal matrix]], [[Wikipedia:square matrix|square matrix]], [[Wikipedia:zero matrix|zero matrix]]).

"Who is John Galt?" The light was ebbing, and Eddie Willers could not distinguish the bum's face. The bum had said it simply, without expression. But from the sunse1t far at the end of the street, yellow gli2nts caught his eyes, and the eyes looked straight at Eddie Willers, mocking and still—as if the question had been addressed to the 3causeless uneasiness within him. "Why did you say that?" asked Eddie Willers, his voice tense. T4he bum leaned against the side of the doorway; a wedge of broken glass behind him reflected the metal yellow of the sky. "Why does it bother you?" he asked. "It 5doesn't," snapped Eddie Willers. He reached hastily into his pocket. The bum had stopped him and asked for a dime, then had gone on talking, as if to kill that moment and postpone the problem of the next. Pleas for dimes were so frequent in the streets these days that it was not necessary to listen to explanations, and he had no desire to hear the details of this bum's particular despair. "Go get your cup of coffee," he said, handing the dime to the 6shadow that had no face. "Thank you, sir," said the voice7, without interest, and the face leaned forward for a moment. The face was wind-browned, cut by lines of w8eariness and cynical resignation; the eyes were intelligent. Eddie Willers walked on, wondering why he always felt it at this time of9 day, this sense of dread without reason. No, he thought, not dread, th10ere's nothing to fear: just an immense, diffused apprehension, with no source or object. He had become accustom11ed to the feeling, but he could find no explanation for it; yet the bum had spoken as if he knew that Eddie felt it, 12as if he thought that one should feel it, and more: as if he knew the reason. Eddie Willers pulled his shoulders straight, in conscientious self-discipline. He had to stop this, he thought; he was beginning13 to imagine things. Had he always felt it? He was thirty-two years old. He tried to think back. No, he hadn't; but he coul14d not remember when it had started. The feeling came to him Suddenly, at random intervals, and now it was coming more often than ever. It's the twilight, h15e thought; I hate the twilight. The clouds and the shafts of skyscrapers against them were turning brown, like an old painting in oil, 16the color of a fading masterpiece. Long streaks of grime ran from under the pinnacles down the slender, soot-eaten walls. High on the side of a tower there was a crack in the shape of a motionless lightning, the length of ten stories. A jagged object cut the sky above the roofs; it17 was half a spire, still holding the glow of the sunset; the gold leaf had long since peeled off the other half. The glow was red and still, like the reflection of a fire: not an active fire, but a dying one which it is too la18te to stop. No, thought Eddie Willers, there was nothing disturbing in the sight of the city. It looked as it had always looked. He walked on, reminding hims19elf that he was late in returning to the office. He did not like the task which he had to perform on his return, but it had to b20e done. So he did not attempt to delay it, but made himself walk faster. He turned a corner. In the narrow space between the dark silhouettes of two buildings, as in the crack of a door, he saw the page of a gigantic calendar suspended21 in the sky. It was the calendar that the mayor of New York had erected last year on the top of a building, so that citizens might tell the day of the month as they told the hours of the day, by glancing up at a public tower. A white rectangle hung over the22 city, imparting the date to the men in the streets below. In the rusty light of this evening's sunset, the rectangle said: September 2. Eddie Willers looked away. He had never liked the sight of tha23t calendar. It disturbed him, in a manner he could not explain or define. The feeling seemed to blend with his sense of uneasiness; it had the same quality. He thought suddenly that there was some phrase, a kind of quotation, tha24t expressed what the calendar seemed to suggest. But he could not recall it. He walked, groping for a sentence that hung in his mind as an empty shape.25 He could neither fill it nor dismiss it. He glanced back. The white rectangle stood above the roofs, saying in immovable finality: September 2. Eddie Willers shifted his glance down to the street, to a vegetable pushcart at the stoop of a brownstone house. He saw a pile of bright gold carrots 26and the fresh green of onions. He saw a clean white curtain blowing at an open window. He saw a bus turning a corner, expertly steered. He wondered why he felt reassured—and then, why he felt the sudden, inexplicable wish that these things were n27ot left in the open, unprotected against the empty space above. When he came to Fifth Avenue, he kept his eyes on the windows of the stores he pa28ssed. There was nothing he needed or wished to buy; but he liked to see the display of good?, any goods, objects made by men, to be used by men. He enjoyed the sight of a prosperous street; not more than every fourth one of the stores was out of business, its windows dark and 29empty. He did not know why he suddenly thought of the oak tree. Nothing had recalled it. But he thought of it and of his childhood summers on the Taggart estate. He had spent most of his childhood with the Taggart chi30ldren, and now he worked for them, as his father and grandfather had worked for their father and grandfather. The great oak tree had stood on a hill o31ver the Hudson, in a lonely spot of the Taggart estate. Eddie Willers, aged seven, liked to come and look at that tree. It had stood there for hundreds of years, and he thought it would always stand there. Its roots clutch32ed the hill like a fist with fingers sunk into the soil, and he thought that if a giant were to seize it by the top, he would not be able to uproot it, but would swing the hill and the whole of the earth with it, like a ball at the end of a string. He f33elt safe in the oak tree's presence; it was a thing that nothing could change or threaten; it was his greatest symbol of strength. One night, lightning struck the oak tree. Ed34die saw it the next morning. It lay broken in half, and he looked into its trunk as into the mouth of a black tunnel. The trunk was only an empty shell; its heart had where trains started out to cross a continent and stopped after crossing it again, as they had started and stopped for generation after generation. Taggart Transcontinental, thought Eddie Willers, From Ocean to Ocean—the 35proud slogan of his childhood, so much more shining and holy than any commandment of the Bible. From Ocean to Ocean, forever—thought Eddie Willers, in the manner of a rededication, 36as he walked through the spotless halls into the heart of the building, into the office of James Taggart, President of Taggart Transcontinental. James Taggart sat at his desk. He looked like a man approaching fifty, who had crossed into age from adolescence, without the intermediate stage of youth. He had a small, petulant mouth, and thin hair37 clinging to a bald forehead. His posture had a limp, decentralized sloppiness, as if in defiance of his tall, slender body, a body with an elegance of line intended for the confident poise of an aristocrat, but transformed into th38e gawkiness of a lout. The flesh of his face was pale and soft. His eyes were pale and veiled, with a glance that moved slowly, never quite stopping, gliding off and past things in eternal resentment of their existence. He looked obstinate and drained. He was thirty-nine years old. He lifted his head with irritation, at the sound of the opening door.
