Journal Journal: Thoughts on confidential computing

https://www.theregister.com/security/2026/07/04/confidential-computings-core-trust-mechanism-is-broken-the-fix-may-not-exist/5266056

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.

One of the hardest parts when switching to Linux was learning to use the command line and shellscripts instead of relying on "power tools" for everything.

I long ago lost track of the number of times I've needed to use the command line to fix something on Windows. You weren't doing anything very complicated if you never did.

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.

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.

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.
