ARMs are just the flashy example: COTS SDR gear and a howitzer also work pretty okay.

I meant that if you intend to use a jammer as a countermeasure against a drone, you're making yourself vulnerable to ARMs. Sure, you can position the jammer away from anything important but that ups your time to redeploy / reconfi

Also known as a perfect beacon for an anti-radiation missile. It's not quite "drones HATE this one weird trick". Yes, jamming is a thing, but so are FHSS, ARMs and any number of other countermeasure-counters. No GPS/GNSS

That's a good point, and required time precision seems like it should be proportional to the velocity of the signal being investigated. I had some bad experiences trying to use gps time for RDF, but that might not apply here. From htt

Probably too late, but if you see this would you mind elaborating a bit? Briefly is totally fine. I posted it to fish for interesting counterpoints.

And even if we could do something about ALPRs, the same outsourcing of the 4th is going on in areas like mobile telemetry.

It was definitely at least partially tongue-in-cheek ^_^ I bet you could figure out the physical aspects. E-ink tech itself has come a long way in the last few years following some patent expirations, and the electronics stuff is basically

You're not wrong about parental enablers, but those without that kind of support basically just end up as freeters. Cost of living is surprisingly low for a first-world country if you've got low standards, so life can be sustained

I just dug an old sb6141 out of a parts bin and hit it with the POCs. Got 400s despite it running an http server of some sort, so not sure how broadly this affects the modem lines. Would definitely be nice to have more comprehensive info on

How about this: e-ink plates plus public-key cryptography. Your actual license number or other identifier, plus a time-based nonce, is encrypted with the DOL's public key. The displayed value changes as the nonce changes according to i

You're preaching to the choir: I personally agree with much of this (lived in metro Tokyo), but that's honestly quite irrelevant. The point of contention isn't whether it'd be better in some absolute sense - it's wh

That's true, though the intent behind posting the referendum was as a reflection of (lack of) direct public support for potentially personally painful measures. Getting something done through legislative channels obviously isn't w

Whenever I see an argument like this I'm confused by how hand-wavey "just achieve societal change" is. Like, sure, there's various issues with various technological approaches, but it's not as if the kind of broad s

While you and the parent are totally correct about the dynamics of power vacuums, I think it's also relevant to note that the robber-baron stuff wasn't exactly happening in some kind of Hobbesian state of nature - it's right

Ah, sorry - I definitely assumed you were operating on a broader definition of lethality than you were and got defensive. I personally agree with the second paragraph as well.

Burning Man is one of the the primary usecases of one of the core devs, so yeah, it should definitely get some good exercise in that kind of context. Another acquaintance is a PAX admin and looking into it for similar reasons.

Should be a fairly straightforward bit of airodump. Even if you don't capture the handshake, you can cross-reference the macs of stations associated with the AP of interest against the mac of your device. If the mac is randomized to a
