Hi HN,

I’m working on an open-source simulation platform called InfraSim. It lets users create companies, build out simulated infrastructure (servers, APIs, networking, blockchains), and then red-team them through fault injection and scenario testing.

The goal is to build a sandbox for learning, experimentation, and security practice, where LLMs and humans collaborate to simulate realistic systems.

InfraSim is still early, but it includes: • An in-browser UI with a component system • Blockchain-backed company creation using Solidity • A “tick-based” simulation clock (inspired by EVE Online) • Human + LLM red-teaming workflows • Persistent state, internal APIs, and networking

It’s meant for ethical hacking, system prototyping, training exercises, and worldbuilding.

The code is here: github.com/infrasimorg/main

I’d love feedback, ideas, contributors, and testers! AMA.

Thank you :)

I guess a good example is things like the physical characteristics of a line drawn by the stroke of a paint brush. You can often see they all align generally in the same direction, and have a sort of "fingerprint"


I mean depending on which side of the brain the tumour is, it could be relevant. Don't quote me on this (I'm not a doctor) but the right hemisphere controls the left side of the body (including left hand) and the left controls the right.


Continuing government contracts, expectation of favours in return, they almost certainly hold some dirt on him (and many others).


And that's story init? Not that anyone "rolls over" for the FBI. We all know it happens. The question is why. in this case it's likely not money. PT has plenty.

1) So what would motivate him?

2) How often do these type of "exchanges" go on, and we have no idea someone's (e.g., politician, journalist, industry titan, etc) actions were dictated by the Intelligence Community? This isn't a conspiracy theory. It's IC 101.


I mean it happens every day. When people have a lot to lose and not much left to gain, they tend to roll over a lot more easily.

As far as what would motivate him: look at what's happening to Musk right now as an example. I'm not saying he doesn't comply and cooperate with law enforcement, but he's certainly being made a big example of right now from all sides.


And payment processors can also identify these. And most of them you have to purchase with a minimum amount on ($10 or $20 afaik).

Virtual debit cards however are interesting. My bank lets me set up as many of those as I like and I don't even have to use my real name or billing address with them.

And yeah, there's also the stolen credit card / debit card market. I really can't see this adding that much pain for these bot handlers. It might make it a bit easier to identify the patterns at least.

I think this will just end up moving the problem further down the line and end up with twitter accounts being bought / sold.


There's no such thing as "one correct answer" to most tasks in any language. In mathematics, maybe. If you're asking it to recall a specific quote verbatim, yeah. But other than that there are many (infinite?) different ways you can paraphrase differently to get the same point across (at least in English).


Leave the microwave running


Build a detector which can differentiate from normal traffic and a "scan" like this.

Wire up an RPI to a motor which reorients a 2.4ghz parabolic dish, first discovering the direction and elevation which best picks up the signal from the "scanner". Then, engage the old microwave emitter you've hooked up to the dish.

You will like as not fry their equipment. Bonus: the attacker may never have children.


That's the best part of it: the technique seems to be passive.


Fry everything then.


Wouldn't you need two microwaves for each axis (XYZ), facing opposite direction? So six microwaves in each room. You have to remove the door switch because you need to leave them running 24/7.


let's not be silly. just put it in the attic so each room is covered centrally. you may need a higher wattage microwave though.


Mine is around 800w. Would a single 1600w be as good in the attic centre as two 800w evenly spaced?


This all makes me wonder on the efficiency of the original idea. if you have 6 microwaves oriented in each of the directions of an XYZ plane, there would be the assumption that the coverage would be radiating out so there are no gaps in coverage. You could then rotate the rig, but that gets complicated for all 3-axis to rotate. But if you're rotating, then why not just one for each axis. Also, is the axis pointing at the ground even necessary to radiate?

So now we have to consider the wattage of a rotating system, and how fast does it need to rotate so the time not directly being radiated doesn't cause gaps in coverage. There's a lot of variable to cover here.


With 96gb of VRAM, will you really need to? Personally I think apple servers might be adopted for AI and LLM workloads soon.


Except edge then opens and presents you with some message about setting it to the default browser (which a lot of people will just click ok to make it go away)


That an internal OS system (help) opens in the OS browser I'm willing to accept. That every browser says "please please make us the default browser" is annoying but hardly unique for Edge. This is just the combination of the two.

I don't think enough people use Win+Type+Enter queries, nor F1 help in Windows to make the discussion very interesting compared to the really interesting ones like which browsers will open a hyperlink in a non-browser app.


Edge is the only browser that periodically captures you in a full screen multiple pages nag screen when it's not default. It's also the only browser able to set itself as default without further interaction.

It's not behaving the same as any other browser.


It does that when it's the default, too. I only occasionally use Windows, so couldn't be bothered to install something else. Yet, I feel that every other time I start it, I'm presented with some "use edge! it's so cool!" screen I have to sit through. It also insists on changing the search engine to bing. I'm usually pretty cautious and try not to press "ok" just so it leaves me alone, yet it managed to change it. For my needs, pretty much every search engine is good enough. I prefer google since I can convince it to use dark mode and use English instead of my local language (even though windows is set to use English as its display language).


How is it more acceptable because it's a combination of two things? Lots of objectionable outcomes are a combination of multiple factors!


Because I accept both things on their own, and I accept that the combination of them follows naturally. Then I must (reluctantly) accept unfortunate outcome of the combination.

I wouldn't say it's reasonable that browsers could never suggest they be made default, and I don't think it's reasonable that you can't have some OS function that wants to show e.g. a help section use the OS embedded browser.


That might be acceptable if no thought went into the combination of the two things.

I accept people must work at height. I accept that people occasionally fall over by accident. We have guard rails and harnesses so that I don't have to accept people falling to their death every time they trip at height.

For example it wouldn't be ridiculous to think that if the browser is tightly coupled with the OS (to the point that it doesn't change when you set the default browser) that you can have the embedded browser opened with a no nag/no ad flag set.


Just because its 2 things you'd otherwise accept doesn't mean it isn't a dark pattern. Lots of dark patterns (like the setting up of privacy / data sharing settings on google) do similar things.


Doesn't have anything to do do with this does it... https://www.politico.com/news/2023/08/11/def-con-hackers-spa...
