In fact this is not the 68000 but its crippled little brother the 68008, which uses an 8-bit external data bus (as the 8088 is to the 8086). That was also used in the Sinclair QL, which was Linus's first computer before he bought a 386 PC and got into Minix. Could Linux now be ported to run on the QL?

You don't have to let a program run forever to determine if it will halt or not. There are other things you can do, like check the state at every state to see if it is identical to a previous state. If so, then you're in an infinite loop. There are other things you can do to prove that a loop will never terminate, but they get more complex.

It is a staggeringly complex problem for a more general case, and you can come up with a handful of specially designed programs that will always break it, but for the vast majority of cases it is solvable.

That's why it seems weird to me that you would immediately ditch the entire concept just because there's one crazy hack program out there that could break it, and only if you've specifically crafted your testing program so that it will fail in that case.

To be fair, the Halting Problem has always confused me because the counterexample to it is highly contrived and it seems like you could reword the problem slightly to avoid the issue. I assume that the description I got in school was incomplete and that it's really the tip of the iceberg of some enormous mathematical model that may or may not be applicable to real life.

Failure to pass this bill means we'll get another chance.

You are quite the comedian. You could have brought the House down with that one. This bill is dead for at least 2 years now, why would a Republican majority Congress bring it up? The only way this bill is going to come back is as an extension of the PATRIOT act that allows for greater surveillance of anybody who makes less than $1 billion per year.

This is the same bullshit they tried to use to kill the ACA, and nobody bought it back then either.

Another thing that dies with DRM systems like this is the mod community. When you have to worry about "cheating" because you intend to make money by keeping features locked behind micropayments, then you can't allow people to mod the game. The first thing they're going to do is install a "free money" button to bypass those micropayment barriers.

But a vibrant mod community can utterly transform a game. There have been two orders of magnitude more code written to mod Minecraft than is in the base game. Kerbal Space Program would just be a toy without many of the mods (which were eventually incorperated into the game). Have you seen what people can do in Skyrim these days? Elite is not going to have any of that because they can't afford to threaten their micropayment income.

What the world *really* needs is a good Automatic Bicycle Sharpener.
