they can't, that's the point. So anon comments will effectively be banned.

since verifying the person is who they say they are is prohibitively hard it'll also do away with user generated content and we can go back to the way things were in the good old days with massive media companies telling us what to think without every tom dick and harry giving their opinion.

The new x86-64 ABI with 32-bit pointers is cool because it allows you to get the architecture improvements of x86-64, such as extra registers and RIP-relative addressing, without increasing memory usage substantially due to larger data structures. Also, 64-bit operations will just use the 64-bit registers. The vast majority of programs simply do not need the extra address space.

One reason that this ABI works so well is that the majority of the x86-64 instruction set uses 32-bit operations. Some operations involving pointers can be done in one instruction without using a temporary register to load a 64-bit constant.

Windows actually also can support this, in theory, but you're on your own in trying to communicate with the Win32 API. The linker option /LARGEADRESSAWARE:NO causes the NT kernel to limit your program's address space to 2^31 bytes.

There are, certainly, some unambiguously 'strategic' weapons, of the 'bloody huge thermonuclear warhead on an ICBM'

Many of the ICBM's have selective yield, and even with the max yield they are not particularly powerful for nukes to be. The most powerful weapons are the ones dropped by aeroplanes, and they typically have megaton yields.

Your pass-phrase is quite tricky to remember and type reliably. A better approach is to use different languages in order to increase the dictionary size. If you pick at random among the languages that use latin script, you can easily get a dictionary size above a million words. Just 4 such words would give a number of combinations exceeding 10^24. Even if you could try a thousand trillion combinations per second, it would still take in excess of thirty years to try them all.

It's lucky you're going so slowly, because you're going in the wrong direction.
