Comment Re:let's play global thermonuclear war! (Score 1) 131

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?)

I call bullshit on the iDRAC as well. I still have access to all versions of the iDRAC from version 6 on and they work just fine with a SOCKS proxy. We retired the R300 with iDRAC5 in 2022, but that's a 2007 machine. We only hung onto it for so long because it was cheap licensing for TSM to backup our GPFS file system. SAS card didn't work with RHEL8 so had to switch to a R330 with Pentium G4600 and that was pandemic delayed. Should have happened in 2020 but meh it was working and limited data centre access so left alone. You would have to be insane to be using a 2007 machine in 2024 for just about anything.

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.”

Anything that goes slow enough to be captured into an orbit will eventually spiral inwards.

Well, most of it (when we're talking matter not already in another black hole). Ordinary stuff orbiting near a black hole gets torn apart by the enormous tides and forms a disk-like structure similar to a gas giant's rings. Interactions among it and with the black hole's magnetic and gravitic fields can eject a bit of it in a pair of jets out along the axis of the disk, powered apparently by the rest of the stuff falling in.

These two black holes wouldn't stick to each other, but start swirling around each other and eventually merge together.

This is partly because of friction with and among other stuff in orbit around the black holes in their "accretion disks". (Black holes experience friction by eating the stuff in the other hole's disk of debris, with the momentum of the black-hole-plus-dinner thus being different from the black-hole-before-dinner.)

It's also partly because the rapid acceleration of things passing near a black hole or orbiting it causes the emission of gravity waves to be strong enough that it carries off substantial energy. (In less extreme environments, like suns and planets, the waves are not detectable by current instruments. In the case of two black holes,orbiting each other, they're detectable from across pretty much the whole universe.) This loss of energy amounts to "friction" that eventually causes co-orbiting pairs of black holes to spiral in and combine.
