the Starways, Killer Crackers from Hell, Mars Incorporated, Dead Inside, and Ninth Dimension Bandits. From them, and others like them, he had picked up whatever shards of data about the Entities’ computational modes that he could find, everything incomplete, a scintilla here and a particle there, a morsel here and a scrap there.
A lot of it was wrong. Much of it was excessively hypothetical. Some of it was entirely the invention of its disseminators. But—here and there, in the two years and two months since the Conquest—certain gifted hackers had managed to learn a few things, little nuggets of fact, that actually seemed to make sense.
They had done it by interviewing anyone who had had a chance to observe the doings of the Entities at close range and seen Entity computers in action. That meant dredging through the recollections of anyone who had been taken aboard the Entity starships, for one thing. Some of these abductees were hackers themselves, who had paid very close attention. There even were hackers who had managed to infiltrate human slave-labor gangs and take part in the incomprehensible reconstruction schemes of which the Entities were so fond. There was much that could be learned from that nasty experience.
And so they had garnered a few clues about the way the invaders sorted and processed and transmitted information; and they had put it all out there on the Net for their fellow hackers to see and ponder. And out of that assortment of crumbs, dribblets, rags, tags, tatters, and wild guesses, methodically filtering out the parts that were incompatible with the rest, Karl-Heinrich had eventually put together his own internally consistent picture of how the Entity computers might operate and how they could be hacked.
—Hello, there. I am Karl-Heinrich Borgmann of Prague, the Czech Republic.
The Bad Texas Vampire Lords, or, rather, the solitary and peculiar boy that lurked behind that particular nom-de-Net, did not rush to share these insights with the other subversive organizations of the hacker world. It might have been useful to the cause of humanity if he had, because it would have advanced everybody’s knowledge of the situation and, very likely, led to even greater understanding. But Karl-Heinrich had never been good at sharing things. There had never been much of a way for him to learn how to do it. He was the only child of remote, austere, forbidding parents. He had never had a close friend, except via the Net, and those were always longdistance friendships, anonymous, carefully controlled. His love life, thus far, had not progressed beyond electronic voyeurism. He was an island unto himself.
Besides, he wanted full credit for cracking the Entity code. He wanted to be world-famous, the best hacker ever. He wanted to be immensely famous. If he couldn’t be loved, he could at least be admired and respected. And—who knew?—if he became famous enough, platoons of girls might stand in line outside his door for a chance to give themselves to him. Which was the thing he wanted above all else.
—Hello, there. I am Karl-Heinrich Borgmann, of Prague, the Czech Republic. I have made myself able to interface with your computers.
Already, beyond any question, it had become clear to everyone who had worked on the problem that the Entities used a digital system of computation. That was welcome news. After all, being aliens, they might have had some altogether alien way of processing data that would be beyond all human fathoming. But it had turned out that even on the far-off unknown star of the Entities the good old binary system was the most efficient way of counting things, even as on primitive little Earth. Yes or no; on or off; go or no-go; positive or negative; open or closed; present or absent; one or zero—there was nothing simpler. Even for them.
The Entity mainframe computers themselves were bio-organic devices with liquid software reservoirs, apparently. In essence, huge synthetic brains. They seemed to be, as human brains are, chemically programmable, responding to hormonal inputs. But that was only an operational fact. In the most fundamental sense they could be understood to be, almost certainly, electrically operated mechanisms: again, just as human brains are. Computations were achieved by the manipulation of charge. The chemical inputs changed electrical polarities; they turned ones into zeros, presences into absences, ons into offs.
The chemical inputs, perhaps, could be duplicated electrically, just as they were in the implanted biochips that had become all the rage among hackers like Karl-Heinrich a year or two before the invasion. Karl-Heinrich set out to try.
—Hello, there. I am Karl-Heinrich Borgmann, of Prague, the Czech Republic. I have made myself able to interface with your computers. This has been the great dream of my life, and now I have achieved it.
He spent a couple of dark wintry days up on the steep hill behind Hradcany Castle, snooping around the deserted streets outside the ancient wall. It wasn’t possible to get into the castle grounds any more, of course, but that didn’t mean you couldn’t tap into electrical conduits that did. Unless the aliens could pull electricity out of the air by alien magic, they needed distribution lines for their power just like anyone else. And unless they had installed their own generating systems within the castle, which was an altogether plausible possibility, the lines had to come in from outside.
Karl-Heinrich went looking for them, and in short order he found them. He was very good at such things. When other little boys had been reading about pirates or spacemen, he was reading his father’s textbooks of electrical wiring.
Now—first contact—
Karl-Heinrich carried his own tiny computer with him at all times, an implant, right there in his forearm—a biochip no bigger than a snowflake, and even more elegant of design. It collected and deployed body warmth to amplify and transmit coded signals that opened data channels, making possible all sorts of transactions. Karl- Heinrich had been one of the first to get implanted, the day after his thirteenth birthday. Perhaps ten percent of the population, most of them young, had had implants installed by the time of the arrival of the Entities. The implant revolution, though still only in its earliest stages, had been widely seen as full of promise for the fantastic flowering future—a future which, unfortunately, the alien invasion had apparently aborted. But the implants were still in place.
Tapping into an electrical meter was child’s play for Karl-Heinrich. Any power-company meter-reader could have done it. Karl-Heinrich was something more than a meter-reader. He spent two days measuring inductances and impedances, and then, too excited now even to remember to breathe, he sent a tendril of electrical energy into the meter and through it, down a surging river of electrons, until he felt himself make contact with—
Something.
A data source. Alien data.
It made him shiver to feel the alienness of it, its shape, its internal structure, its linkage configurations. He felt as though he were walking the mysterious glades of an unutterably strange forest on an unknown world.
The system through which it was flowing was nothing like any computer he had ever known, or even imagined. Why should it have been? Nevertheless he sensed familiarity amidst the strangeness. The data, however strange, was still only data, a series of binary numbers. The shape of that digital flow was weird and bizarre and yet he felt somehow confident that it was well within the reach of ultimate comprehension by him. The alien device into which he had tapped was, after all, a system for the manipulation and storage of data in binary form. What was that, if not a computer?
And he was inside it. That was the important thing. A hot tingle of sheer intellectual joy ran through him at the contemplation of his triumph. It was almost orgasmic in its intensity. He doubted that sex itself could provide such a thrill. But of course Karl-Heinrich had very little grounds for such a comparison.
It took him quite some while to understand the particular nature of what it was that he had touched. But gradually it dawned on him that the program within which he was wandering must be the master template for the whole electrical distribution grid; and suddenly there was a map of the Entities’ electrical system superimposed on the map of the castle grounds that he had in his head.
He explored it. Very quickly he found himself trapped in a blind alley, went back, took another path. Another and another. Hit a roadblock, went around it, plunged forward.
His confidence grew from hour to hour. He was discovering things. He was learning. Things were adding up. He was piecing together correlations. He had found channels. He was getting deeper and deeper in.
The delight was intense. He had never known such pleasure.
He copied a swatch of data from an Entity computer, downloaded it into his own, and was pleased to see that he was capable of manipulating it by adding or subtracting electrical charge. He had no way of knowing what changes he was making, because the underlying data was incomprehensible to him. But it was a good start. He was able to access the information; he was even able to process it; all that was missing was some way of understanding it.
He realized that even at this primitive stage of his penetration of the system he should be able to send the
