This is also a problem in classical HPC, there aren't very many algorithms that can scale linearly with cores. That's partially why so many HPC algorithms tend to be built on matrix multiplication and Monte Carlo,…
You were one generation before me, I started college in 2007. By then it was all those super cheap little 4 port Netgear switches most people reading this have probably owned at some point. I don't remember us having…
Hubs were still just barely still relevant when I first started learning networking, but it was late enough that I don't think I've ever encountered one in serious use. Especially after port mirroring became a common…
People may forget that Ethernet originally had a shared transmission medium and collisions were a serious limitation. Switching was a later addition that mostly solved collisions and really paved the way for Ethernet as…
GL.iNet is more open (they run an OpenWRT fork that they open source with a proprietary GUI on top). They have a beta for a mesh system on top of that: https://www.gl-inet.com/en-us/pages/mesh . I haven't tried the…
See ntopng, it provides a nice monitoring UI for exactly this type of scenario. It's higher level than Wireshark, more focused on high level traffic analysis.
I have a Studio 2 for work and even on windows it runs like absolute garbage. Almost unbelievably slow at everything and locks up frequently. Maybe I have a dud with some sort subtle hardware fault but it's by far the…
SELinux was originally designed by the NSA to serve their needs, which are probably a bit more intense than "normal" users, and that was over 25 years ago. I'm not convinced a fresh effort couldn't do better, though I'm…
They do use the official client, but it also makes it fairly easy to bridge tailscale networks with regular wireguard clients with normal routing rules.
PfSense and OPNsense both support Tailscale and can integrate it with their normal routing/firewall behavior. I think OpenWRT can as well but I haven't tried it.
The prospect of going to a website I've never visited before, getting a captcha, and it saying "we don't think those are YOUR feet, access denied" is a little TOO believable.
"We reserve the right to retain your security feet pics indefinitely, but won't use them for advertising purposes." --new TOS
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…
