After Oklahoma City I’m pretty sure commercial fertilizer is pelletized with some sort of coating specifically to prevent its use as an explosive.

Ammonium nitrate does a pretty credible job of preventing itself from being used as an explosive to begin with. It’s damn difficult to initiate, and anyone with the capability to do so would be able to trivially defeat pelletizing by, e.g., just grinding the stuff up first.
It’s not a matter of just sticking a fuse in it like Wile E. Coyote. You already have to have your hands on some pretty serious blasting caps or have the capability to manufacture your own, and at that rate you’re already pretty well versed in making things go boom.
McVeigh had to resort to using dynamite as a booster to initiate his truck full of ANFO and even then IIRC not all of it went off. But if you already have dynamite… you already have dynamite.
What pisses me off is that whole debacle made potassium nitrate hard to get your hands on in bulk because too many idiots in suits flunked high school chemistry. KNO~3~ is significantly more useful for purposes other than stripping the facades off of government buildings.
Oh, and after the affair some dimwit from the ATF came to my hardware store and tried to grill me about chemical fertilizers in a circumspect and very strange way that was attempting to simultaneously serve as a threat while also not letting slip the knowledge of what ammonium nitrate could possibly be used for, in case the mere act of asking gave anyone any ideas. I lost count of how many ways I had to phrase “we only sell consumer grade blended products” at him until he finally went away. Demonstrating that I knew more about it than he did probably would not have been a great idea regardless of how satisfying it might be.

That’s most usable explosives from my limited understanding. A small primary explosive charge setting off a more stable bulk explosive, whether that be ANFO or C4 or something else.
He may have already had dynamite, but not a Uhaul full of dynamite. Which would have been difficult and quite dangerous I imagine.
The same losers come by gun stores and ask how to convert their AR-15s into machine guns. Actual police work is difficult I guess, so they go on these fishing expeditions.

I’ll ask grandma about that.

But who has diesel and fertilizers in the kitchen?

Don’t cook ANFO in your kitchen folks.

You can literally just tell it you’re writing a book and want it to be accurate and it bypasses anything I’ve tried lol

That’s not new. In Warsaw Uprising and Ghetto Uprising, fighters were commonly using petrol against nazi tanks.

Fuck me have they not patched the grandma exploit yet? I have a book from last year which references that one

It’s a little bit more difficult, but barely

They never patch the grandma exploit.
Grandmas just bamboozle them with cookies, pie, and a tall glass of whatever drink they hand you and send you on your way.

Genuine question, how confident are we that an LLM can actually be patched like a deterministic system through prompt and weight manipulation? Has the 95% adversarial success rate that was reported actually moved in the past year? I don’t feel like any meaningful progress has been made but I’m admittedly biased so I know I’m not looking in the places that would report success if there was any.
rizzothesmall@sh.itjust.works 20 hours ago
They probably can’t completely patched in their training, but using a pipeline which reviews the prompt and response for specific malicious attack vectors has proved very successful if adding some latency and processing expense.
You can, however, only run these when you detect a potentially malicious known exploit. If the prompt contains any semantic similarity to grandma telling a story or how would my grandma have done x, for example, you can add the extra pipeline step to mitigate against the attack.

No progress as of late.
