It's a genuine question, I don't have an argument for impossibility or anything, I just don't see how revocation could practically be done. In scenario A, Joe Schmo buys a camera, happens upon a powerful politician in a compr

I don't know much about GPGPU-land, but all of the difficulties I foresee have to do with multiprocessing/sharing/context switching... my guess is that only one logical program can use the scratchpad at a time?
937.
by dooglius 7y ago
Moving to e.g. shared scratchpad memory would be a major paradigm shift, you'd have to do a lot of coordination between CPU vendors, OS/kernel developers, high-performance library writeslrs, etc to make it happen.

If it's possible to desire things without happiness, what is the evolutionary rationale for happiness at all? Maybe what we call "happiness" is only one type of positive feedback among many of which we might be less aware.

Is there any reason to disbelieve it? It seems like a reasonable thing to try.

No, it means drastically reduce the population size; the implementation of this is orthogonal to the point.

Everything you describe could exist as a paid service, and I suspect would be much higher quality that way.

This sounds pretty similar to what goes on now, except that the channel processor sits on the other side of the (e.g.) PCIe connector.

Health is neither boolean nor one-dimensional, but we can still say an allergy to nuts is less healthy than not. The same can be said for autism.

Google's definition of "identity" definitely does not capture the word as I understand it, and as I believe the GP was using it.

Well, I think one issue is that evolution acts on base-pair mutations and not traits. So (to wildly make a possibility up) suppose that mutations X, Y, and Z are each individually beneficial, but having all of them at once gives you autism.

by dooglius 8y ago
I agree with your general point, but there are very clearly people who would choose to remain autistic, given the opportunity.

The "extreme portability" he's talking about is portability of projects to compilers and libc implementations that behave badly, possibly in standards-violating ways like this.

That works fine when an application just wants to protect a private key in memory. But if you want to build, say, an application where a user enters via keyboard information that you want to protect from another application, you have to wor

One issue I see here is that time protection would need to extend to anything shared, not just CPU micro-architecture. For instance, if a hard drive has a DRAM-based cache, that could be used as a timing channel, and the complexity of flash
