Face scanning tech also depends on the data set being valid. The DOD has been compromised many times by airwall violations, security violations, improper screening, and extremely buggy software from Cisco and Microsoft.

All the enemy needs to do is write a rootkit that flips a couple of bits. The robot army now faces the other way and friends are identified as foe. I wouldn't put it past a group like the Lazarus hackers to be capable of such a stunt. We already know the enemy is capable of GPS jamming and GPS spoofing, because they've done so to hijack US drones, and that's another potential vulnerability.

US military robots are also known to have severe problems identifying that a person dressed as a tree is a person, not a tree. A skillful enemy could walk through US robot army lines without impediment, unless the US robots shoot indiscriminately. But if the US robots are genocidal, mutually assured destruction becomes a viable tactic. You can't be more than dead, after all.

And if the US includes a death switch, given that US defence contractors don't always wipe hard drives and the military don't psychologically screen very well (Manning was known to be seriously mentally unstable prior to deployment, for example), there's absolutely no guarantee the enemy won't simply learn it and spoof it.

I just don't see how the US think this could possibly work.

Its success rate in Israel stands at somewhere between 1% and 0.1%.

One gun can shoot at one target at any one time. If your AI-guided robot army is shooting up chicken farmers and goat herders, it's ergo not shooting at the army that's flanked it which threatens to overrun the opposing side's now largely undefended turf.

A robot army can also be taken out by EMP weapons - basically tax nukes. Since robots can't distinguish between soldiers, civilians, and cake stands (AI is pretty dumb), the defending side already faces complete genocide. You can't get any deader than that, so there's no incentive to not flatten the enemy with nukes and a very slim chance they won't fire back, because it's hard to maintain an expensive nuclear defence and an extremely expensive robot army at the same time.

(Basically, same reason the US is now outgunned on fighters, the new ones are so expensive they can't afford that many. The US relies utterly on them being more destructive faster, but again, what's the point in NOT invoking MAD when your enemy has demonstrated they're genocidal and no respectors of the norms and laws of war?)

It's not what it lacks. It's because it uses newer components. As you make the transistors smaller and reduce the voltages, you increase the damage a cosmic ray strike will do. Yes, the chips are rad-hardened, but anything that gets through will have greater impact and have a greater risk of frying a component versus flipping the bit. The rad hardening will also have improved, but the risks will have increased faster than the protections.

However, there will undoubtedly be better error-correction in NH at circuit level, Voyager only error corrected the communications not the processor or memory. So I fully expect bit flips to be fixed silently, so I expect data to be of greater robustness. So in terms of quality of output, I expect NH to beat Voyager by a long way.

(I'm ignoring the efforts by the anti-science lobby to shut down NASA and the Deep Space Network. If they succeed, all communication will be permanently lost. But that won't be a technological fault, that will be a massive social fault on a scale comparable with Crusaders destroying the Imperial Library in Constantinople.)

Linux won't capture the desktop market unless Microsoft is broken up due to them repeating antitrust activity they have been repeatedly convicted of. But that won't happen because the US is too dependent on its supply of what's basically electronic heroin.

Sun tried to go the Networked Computing route and bankrupted themselves.

Internet connectivity is far too slow and far too unreliable for most tasks. Worse, most apps still use TCP and UDP, despite better transport protocols existing. And IPv4 is still mainstream, despite IPv6's benefits.

The Internet is also not secure, due to NSA demanding the IETF withdraw IPSec as a mandatory requirement for IPv6.

No, thin clients with overpowered central servers (the mainframe architecture) was abandoned for good reasons and every attempt to return to centralised computing has failed for good reasons. Companies are now even starting to abandon the cloud.

Submission + - Peter Higgs, physicist, dead. (theguardian.com)

jd writes: Peter Higgs, the Nobel prize-winning physicist who discovered a new particle known as the Higgs boson, has died.

Higgs, 94, who was awarded the Nobel prize for physics in 2013 for his work in 1964 showing how the boson helped bind the universe together by giving particles their mass, died at home in Edinburgh on Monday.

After a series of experiments, which began in earnest in 2008, his theory was proven by physicists working at the Large Hadron Collider at Cern in Switzerland in 2012; the Nobel prize was shared with François Englert, a Belgian theoretical physicist whose work in 1964 also contributed directly to the discovery.

A member of the Royal Society and a Companion of Honour, Higgs spent the bulk of his professional life at Edinburgh University, which set up the Higgs centre for theoretical physics in his honour in 2012.

Prof Peter Mathieson, the university’s principal, said: “Peter Higgs was a remarkable individual – a truly gifted scientist whose vision and imagination have enriched our knowledge of the world that surrounds us.

“His pioneering work has motivated thousands of scientists, and his legacy will continue to inspire many more for generations to come.”

This is also vanilla RAM. Well, rad-hardened to the best of their ability back then, but as far as I can tell, there's oy error-correction in transmissions, not in the RAM itself.

https://destevez.net/2021/12/v...

Error-correcting RAM is used in business on Earth because cosmic rays can corrupt data over the brief lifespans of a business server. Imagine being in deep space with no atmosphere, no magnetosphere, and no heliosphere. The radiation the Voyagers are having to endure is orders of magnitude greater than designed for and for decades longer.

That a chip has fried is news because it's just one. NASA does amazingly well, but I doubt New Horizons will last as long, and I sincerely doubt any private firm will be capable of building a probe that can Voyager's achievements.

The article actually does a good job of talking about this. It even mentions recent problems that they had in Alaska with a cable that got cut because the ice got thicker than they thought possible. I actually think that this is a pretty cool idea (pun totally intended), and I am glad to see these guys making 23 million euros to look into it. Good on them for getting paid to study a very interesting problem.

However, I would be surprised if the cable actual got laid, assuming that the current forecasts are remotely accurate. This fiber optic cable is already forecast to cost 4 times as much as a cable that took the conventional route. It is also going to be considerably more expensive to maintain. The main selling point appears to be that it is less likely to sabotaged (unless your adversary has access to nuclear submarines, I guess), and it is also less likely to be cut by an errant anchor.

There's a reason that so many of the undersea cables follow essentially the same routes. That reason is cost. No one wants to sink hundreds of millions of dollars into a cable that is going to have a serious price disadvantage.
