Real-time Packet Analysis with Python

The program had the look of a cheap plastic arcade game. Console cowboys, all of them, so sure of their skull guns. The matrix had its own logic. He flipped the channel selection program and began to punch in the coordinates of the Berne clock. The sky above the port was the color of television, tuned to a dead channel.

Data was the new oil, flowing through fiber optic arteries that pulsed with the heartbeat of the information age. Case punched his deck, and the matrix unfolded around him like digital origami. Night City was a sprawl of neon and chrome, where algorithms walked the streets in human form.

The towers that rose beyond the port’s rim gleamed like vertical miles of polished steel. His ugliness was the stuff of legend. Console cowboys, all of them, so sure of their skull guns. The future is already here—it’s just not evenly distributed.

He’d operated on an almost permanent adrenaline high, a byproduct of youth and proficiency. The construct was a kind of piloting program. Case was twenty-four. At the steel cord above his head, he could see the glow of the city’s neon matrix.
