Comment The challenge (Score 1) 87

Is to set coursework and exams that are specifically crafted to exploit where AI is weak or prone to hallucinate.

You do not ban cheating, because those who cheat will inevitably find ways to circumvent the ban.

Rather, you exploit the properties of the mechanisms of cheating to ensure that those who actually understand the ideas are marked relatively highly (regardless of whether they reach the textbook conclusion) and whose who do not understand the ideas cannot do well even if they give what is in the textbook.

The interest should not be in precise answers, but in precise use of tools of reasoning and analysis, because this is what actually matters when it comes to understanding. Yes, it means you can't standardise so easily, and you have to devise things in ways that don't penalise intuitive thinkers over methodical thinkers, but you cannot teach a subject properly if you are only concerned about the surface.

> That feels like an odd thing to be frightened of. It's not Mars where there are minutes of latency. Why would the Philippines - specifically - be any more (or less) concerning than if the drivers were in a building a kilometer away from the vehicle?

Half-way across the world and thus more prone to latency spikes. Not something you want when you need to be able to react quickly. Or have you never played a game on a server on the other side of the pacific?

Comment Priorities (Score 4, Interesting) 77

Years back I was interviewing people for a coding position. We went through the standard tech stuff and then did a bit of project to see how they thought. We said (this is circa 2009'ish I think) - imagine you're on a team creating a new phone. You don't have time to test all the functions, so which would be your top two functions to ensure working?

All a bit Kobayashi Maru - obviously you can't release a phone testing only two functions, but we wanted to see what they'd prioritise. The very best answer we received was this one: "I would make sure it has the ability to call emergency services." Their thinking was that this was likely the most critical feature of a phone for both a user, and also for the manufacturer to avoid being sued. Absolutely great answer.

And yet here we are, with the post above. Taking the thinking of this interviewee - the ability to work with emergency services is important for general society, for the user of the vehicle (so they don't get in trouble) and for the manufacture of the vehicle (so they don't get fined/sued/both). Absolutely critical.

You can get Veracrypt to work with the Mac, via FUSE, but I don't know how safe/robust that is. It's probably more secure than anything Apple has. It's certainly more secure than anything Microspot has.

But, yeah, it's getting extremely irritating that useful stuff is being taken out of commercial OS' and junk put in.

Comment Re:The secret word is "trust". (Score 1) 2

The DoD is known for viruses transporting payloads across airgaps onto Internet-connected machines. One thing it isn't is "so secure".

But, to the extent that it IS secure, it uses pretty much what I outlined. They use Class 3 certs for all users and all machines, and have done since about 2001. The US Navy got to trial run thei system to shake down the defects in the design, before they rolled it out to everyone. Beyond that, they use segregated networks (in principle, physical separation rather than logical separation, but who knows?) and encrypted communications.

What I've done above is take what the US DoD uses today, threw in what the US DoD recommended but never actually implemented in the 70s to fill in some of the gaps, and also included what the US DoD implemented and actually used in the way of Trusted OS deisgns in the 70s and 80s. The NSA and IRS likely use some variants on the same techniques.

So, what I've got above is pretty much why the DoD is as secure as it is.

What I've done is augmented it to handle the fact that you need to verify the hardware and not just the endpoint, and that you need to verify the physical host independently of the logical host. But that's pretty much it.

The claim in The Register is that confidential computing might not be a fixable problem. I am not going to claim I have "the solution", or that the solution I have come up with meets either the requirement of being necessary or sufficient, but I would argue that it adequately challenges the assumption that the problem cannot be solved at all.

That is true, but the archaeology shows that this won't work for all island-hopping or all river navigation.

For example, we have clear evidence of hominins not just living on islands across the Mediterranean when no ice was present (it was free-standing water) but commuting to and from shore. We also have evidence of technologies travelling upstream along river-based communities at speeds that cannot be accounted for by simply walking.

So we need a model in which they could actively navigate against the water flow AND across significant distances of open water.

Comment Re:Interesting and disappointing (Score 2) 19

We know that boats built 1.1 million years ago (so around the time of the split) were capable of going long distances up/down rivers between settlements, and across open waters beyond visual range to islands. This places certain language requirements on the hominins of the time, although we can't be sure hobbits had full access to all of those requirements. (There's not much evidence of boat building.)

However, they must have genetically had the capability, whether or not their brains were large enough to make any use of it.

Comment Re:Interesting and disappointing (Score 1) 19

That is all perfectly true, but we have a problem. Boats were capable of navigating reliably and robustly up/down rivers and across open sea beyond visual range. This requires much more complex communication than a gorilla or a chimpanzee is capable of, but obviously orders of magnitude less than a modern human or a Neanderthal.

It would seem reasonable to say that homo florensis was as much like us as those who first built deliberate boats for voyages requiring complex navigation.

Comment Re:1 million years ... (Score 2) 19

The homo genus arose 2.2 million years ago. Evidence of complex communication exists as far back as 750,000-1.1 million years ago. Homo sapiens arose 300,000 years ago and are technically the "modern humans" as far as outward physiology is concerned. The brain was the size of modern humans for much of the 2.2 million years, but it is disputed how much. Since homo florensis is clearly not being likened to modern humans in the morphological sense, it would seem reasonable to conclude that they must be talking about some intellecual capability.
