25 years is the standard time horizon for automatic declassification, and someone high up probably decided to collect things together to publicize in an attempt to score some political kudos.
Speakers can act as part of a useful microphone circuit but you're missing all the amplifiers and ADCs and other stuff to use it as one in any sane speaker driver circuit. They'd have to intentionally add all that,…
Yeah I think I explained it badly. They sorta stream through the detector until they interact, and then potentially undergo multiple compton scatters or photoelectric absorption (or other weird stuff) that produce…
Spinning shield is a thought people have had but it doesn't work very well in practice (for gamma imaging). Usually you want to avoid anything that blocks gammas as much as possible because you need every one you can…
It was probably an imaging radiation detector regardless, the spinny bit would likely be some sort of camera to add context to the radiation image. Imaging detectors can get a lot fancier than just two planes. One…
The cheapest worthwhile detectors out there are the Radiacode ones. They are excellent for what they are, but they run around $300. Cheaper Geiger counters are unfortunately kinda useless, at least for this. It's also…
Unfortunately smart phone cameras kinda suck performance wise. Radiation detectors fundamentally need some mass to actually absorb and detect radiation, so while cameras are basically similar to semiconductor radiation…
Not us, but probably an imaging radiation detector with LIDAR. Its another technology for search, with its own tradeoffs and advantages. We are friends with a couple companies that make that tech, but it's a different…
They are more prevalent than you think, especially in places like ports and airports. But part of the problem is they are typically expensive for anything more sophisticated than a basic Geiger counter, like most…
Ha, that's me. Thanks for posting this. It's late where I am but I can answer questions. I took a brief break on this topic after I graduated and worked on other stuff, but the company I'm at now has done a lot of…
Good luck. I'd wager that most methods to protect your privacy aren't nearly as effective as we think they are. While I don't think it means that you shouldn't try to protect your information, I typically assume that…
> Newer linux folks like it because they're used to it, people who don't like it use devuan, gentoo, or one of the others that still lets one use openRC or whatever else. This is a bad generalization. Counterpoint, I've…
Companies like Red Hat/IBM operate in Illinois and for better or worse have controlling interests in Linux and across open source projects pretty broadly. Wouldn't they be forced to include the capability in their…
Actually, someone walking around with a detector and us localizing in real time is what the current state is. There's been a lot of development since this dissertation to let it run in real time, and to integrate with…
University server seems to be acting up a little bit, I think they just migrated to a new platform but this is the link: https://repository.lib.ncsu.edu/items/451b001d-e63a-4968-866...
This incident inspired my PhD dissertation on radiation source search. The techniques to search for sources like this are remarkably primitive, even today. My company works on this tech, but it's hard to get traction…
And they got that position of dominance more via shady deals and sketchy practices than by producing excellent software. Microsoft has done some good engineering, but that's not what made them what they are.
A complication is that AUR doesn't publish packages, it's more like FreeBSD ports in that they are the build scripts for packages and the user builds the package on their local machine. Building an AUR PKGBUILD…
https://dnschecker.org/ip-blacklist-checker.php is pretty handy for checking if you're on any of the major blocklists.
There's really two ways, the other is to manage your own CA. But it seems like every browser/piece of software/etc out there is hell bent on making that as difficult as possible. It'd also be nice if it was easier to…
Pfsense or OPNsense can handle ~5 gbps routing/firewall on a low power AMD or Intel embedded chip. My now old Pfsense box I got off Aliexpress can comfortably handle 2.5 gbps on an ancient Celeron J4125 running around…
Damnnnnn that's cool but ouch. I know you're really buying the whole platform and capability and flight-worthy certification but $2K for what is basically a wifi dongle still makes my head spin.
It was still small enough to be relevant but yes. The level of integration Valve can do with the steam box probably actually lowers the total cost for them a bit versus just comparing against individual component cost,…
Linus Tech Tips did a video a few days ago where they built a DIY Steam box for the same price. What they came up with was a decent improvement on the GPU but not a massive upgrade. Kinda suggests Valve isn't…
To be fair, "boffin" usually implies someone has relevant (usually scientific) expertise, but nerd doesn't. Henry Legg has the relevant credentials to give weight to his claims, he's not just some random basement nerd.
