poison null byte: 3, 7, 9
Brought in to investigate a computer problem at the Treasury, Lt. Jaing provides Ellik with a program that doesn't quite do what he said it was going to. Soon after that, his viruses start acting strangely; someone's figured out what he's up to, but hasn't turned him in. Seems like there's another player on the networks, with their own agenda.
3: What’s your favorite line of narration?
“Besides, I’d rather not snuff someone for being smarter than Jaing,” said Mereel, tipping backwards in his chair. “Who knows where I’d have to stop?”
That's a weasel answer because it's mostly dialogue, so -
She was twisting in the wind, all by herself, and the Nulls had plenty of rope.
7: Where did the title come from?
A poison null byte is a legitimate exploitation technique. Embedding a NULL byte/character in a string at a certain point can cause a vulnerable application to parse the rest of the string as a command.
In other words, the appearance of an unexpected NULL drastically changes the effects of an action. As Thujerya has discovered.
9: Were there any alternate versions of this fic?
This fic started off as a spite write. In RepComm, Jaing uses the cliched trick of sending the rounded off fractions of a cred off to another account to siphon off money for the Nulls. This is not how a competent slicer would rob a bank, so obviously a fix-it fic was needed.
Deciding where and how to diverge from the books took a while, especially changing how Etain might handle her pregnancy. Then there was making an OC to act as a foil to the Nulls, and once Thujerya existed she needed a backstory, and after that what to do about Kal Skirata...
Thankfully, some of the snippets are reusable. The following bit was chopped from a more intense interrogation session that wasn't at Etain's safehouse, but fits in what will be the next chapter;
Mereel leaned forward over the table. Her back was cramping with the effort to stay upright, but Thujerya refused to give him the satisfaction of seeing her flinch.
“Another more thing,” he said. “How’d you get into Jaing’s setup?” He nodded over at the other clone. She tapped her fingers on her arms, a quick ripple to reassure herself, and dug her nails in.
“Cuckoo’s egg in the exfil data, zero-day in your parsing library,” she said.
“Fierfek,” said Jaing. He said it like a curse. “That was walled off.” Not well enough.
She lifted a shoulder and dropped it. “Chained up and out of the ‘viser.”
"How - you must've - " The clone's voice was taut with exasperation. Annoyance. Given the kidnapping, she felt entirely guiltless at his frustration. Hoped Mereel shared it.
