"Don't Be a Dick"



DON'T BE A DICK
By Curtis C. Chen

"What's up, Doc?" blared the computerized voice from the speaker above the CRT.

Lisa turned off the speaker. It would be much easier to do this if she didn't have to listen to the machine actually talking to her.

Even though the voice was crudely synthesized, it made the AI seem more human. And Lisa couldn't think of it as a person right now. She had to remember that it was just a program—just a piece of software she'd written, a bunch of ones and zeroes.

She'd left this copy of the "Battlefield Intelligence Global Master Control" program running on her home computer during her sabbatical. The AI was a remarkable achievement, but the primary BIGMAC—the one running at Fort Baxter and being trained to wage war—had turned out to be uncooperative, unstable, and just plain mean. The military was talking about shutting down the entire project.

Lisa had already made her own decision on that.

She'd been hoping her home copy of BIGMAC would show some positive qualities, since it had been isolated from the Army's bad influences, but it was still as childish as ever. Its first interaction with Lisa upon her return had been to demonstrate a new trick: modulating its audio output to simulate different types of flatulence.

The screen blinked. WOULD YOU LIKE TO PLAY A GAME? the BIGMAC asked.

NO MORE GAMES, Lisa typed.

The military had insisted on the BIGMAC having all kinds of failsafes so that nobody could disable it in the middle of war operations. But Lisa had secretly built in a killswitch, and a message to remind herself what the passcode was.

TELL ME ABOUT THE RABBITS, she typed.

That was the trigger phrase. The screen filled with text:

COME AND DANCE ON ON OUR FLOOR
TAKE A STEP THAT IS NEW
WE'VE A LOVEABLE SPACE
THAT NEEDS YOUR FACE...

THERE'S A HOLDUP IN THE BRONX
BROOKLYN'S BROKEN OUT IN FIGHTS
THERE'S A TRAFFIC JAM IN HARLEM
THAT'S BACKED UP TO JACKSON HEIGHTS...

WHAT WOULD YOU DO IF I SANG OUT OF TUNE?
WOULD YOU STAND UP AND WALK OUT ON ME?
LEND ME YOUR EARS AND I'LL SING YOU A SONG
I WILL TRY NOT TO SING OUT OF KEY, YEAH...

YOU CAN COUNT ON ME
NO MATTER WHAT YOU DO
YOU CAN COUNT ON ME
NO MATTER WHERE YOU GO.


What the hell? It took Lisa a moment to remember how she'd programmed this part.

The computer's security keypad would accept a numeric code now, and that would shut down the BIGMAC completely. These verses were a hint to indicate the five-digit code she'd chosen. That's right! Got it.

The screen blinked again. HEY, WANT TO HEAR A JOKE?

SURE, Lisa typed. Maybe the BIGMAC could still redeem itself.

KNOCK KNOCK.

WHO'S THERE?

3.

Lisa frowned. 3 WHO?

3======D, the BIGMAC printed. HA HA HA! YOU TOTALLY FELL FOR IT!

"Okay, you're done." Lisa was glad she'd turned off the speaker earlier.

She entered the shutdown code, and the screen went dark.

"At Close Range"



AT CLOSE RANGE
By Curtis C. Chen

The guard held up the unlabeled cassette tape and looked at Lisa. "What's this?"

She'd been practicing her answer in front of the bathroom mirror, but her heart rate still accelerated as she stammered, "Just some music. You know, background music for while I'm working. It gets kind of lonely in that big empty computer room all by myself."

"Uh-huh." The guard narrowed his eyes. "What kind of music?"

"It's the new Madonna album," Lisa said. "I have the LP at home, but, you know, it's not really convenient to carry a record back and forth."

The guard looked to be in his fifties, and Lisa wondered if that stony stare had won him many poker games. She felt her palms sweating as she waited, not wanting to say too much.

After a moment, the guard put the tape down. He fished around inside her purse, found her Walkman, and set it on the counter next to the tape.

"Nice lady like you ought not to be listening to music like that," he said, not looking at Lisa.

"Well, I think she's a real inspiration, but to each his own. What kind of music do you like?"

"I like Johnny Cash."

"Right," Lisa said. "Because shooting a man in Reno just to watch him die is so much more wholesome than, you know, sex."

The guard gave her that look again, then loaded everything back into her purse and slid it across the counter.

"You have a nice evening, Professor," he said.

"Do my best," Lisa muttered, grabbing her purse and hustling out of the building.

***

The PLAY button on the tape deck popped up with a clank. Lisa stopped writing in her notebook and turned back to the computer. She entered a command to verify that the data from the tape had transferred successfully over to the hard drive:

X:\>dir /w

 Volume in drive X is BIGMAC
 Volume Serial Number is 1234-5678

Oh no! Where is it? Lisa's heart skipped a beat before she remembered that she'd encrypted the contents of the tape. That's right...

She had been confident that the exit inspection guard at the Army base wouldn't know that audio cassettes could also be used to store digital computer data, but a little paranoia never hurt when it came to security measures—especially when you were smuggling classified information out of DARPA. Lisa couldn't sleep at night unless she made off-site backups of her code, and it was easier to circumvent the restrictions placed on her government work than to argue with the military.

The problem was, Lisa couldn't remember the passphrase she'd chosen. She was pretty sure it was a three-word phrase, and she knew she'd coded it into the fake filenames based on helical scan, the way data was actually written onto tape—maybe those numbers in the file extensions were a clue? She wouldn't be able to recover her project until she figured it out...
