  • Announcing “BootAble” – GRC's New Boot-Testing Freeware
    Please see the BootAble page at GRC for the whole story.
  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

I am a little behind on the show so, if you have already discussed this, well here it is...
I am speaking from experience of Physicist currently working on narrow, specific AI
system in Medical diagnostic field as Data Scientist (objective diagnosis of autism
from functional MRI brain scans).
1) Leo wrongly assumed that just because it is complex and powerful software
built on foundations of deterministic algorithmic hardware, AI is somehow
non-deterministic. No matter the complexity and power of software and hardware
it all must reduce to actions in that deterministic algorithmic foundation.
Deterministic.
2) Term not yet discussed is maybe more important: "noncomputable".
Incapable of being computed by any deterministic algorithm in any finite amount of time.
This goes beyond just inability to get random numbers, as Matematician and Physicist
R.Penrose Nobel Prize winner showed, mathematical properties of self awareness
require it to be noncomputable. That has consequences for AI, it can't ever be
self aware (yes, there are so called Strong AI theories which just assume that with
enough power and sophistication AI must develop self awareness but, by
Math of it in my opinion that is as stating that if we just had enough power and skill
we could fly by pulling ourselves up by our bootstraps).
How are we self aware?- It turns out that there are noncomputable processes in Nature,
Physics, Chemistry, Biology. There some of them known to be ongoing in our brains.
(Side note, just because something is quantum mechanical does not make it
noncomputable, quantum computer need not be!)

Leo wrongly assumed ... AI is somehow non-deterministic.
I'm no expert, but I have investigated the basics enough to know that computer generated randomness is frequently part of the algorithms, both during training, and during execution of the user interaction. One can argue about the ability of a computer to be truly random, but it's my understanding that Intel CPUs have the RDRAND instruction which uses "true physical randomness" to at least seed the random number generation. Given that the algorithms use randomness to intentionally produce a different answer for the same input(s), I agree with Leo.
