- the Recycle Bin made it much simpler to 'recover' accidentally deleted files, no more FAT16/32 undelete tools (anyone else remember Revive or was it Revival?) for most mistakes

And these days, we have come full circle, and need the PC undelete tools again to recover files from the SD cards in our phones.

Choosing your parents wisely seems to be the main means to becoming rich. More so with every generation.

Until raising children becomes the responsibility of the state and inheritance is abolished, I don't see this being preventable.

The drift can (and historically, has been) reset every now and then, through pitchforks and torches. But the bigger and more powerful a nation is, the longer it takes to reach the critical mass for revolution.

This is Russia. This is Russian Government. I'd wager illegal is whatever they decide it is.

Logically, it's not much different from the US government's Feinstein Amendment banning posting recipes for how to make explosives.
In either case, it's suppressing knowledge instead of the illegal actions themselves.

Only in degree, not in validity.
Even with a slug, terminal velocity is going to be lower than muzzle velocity, at any angle.

This must be so, because:
- Horizontally, the speed is always going to decrease due to drag.
- Vertically, in order to propel a projectile to a height, you have to overcome the drag to reach that point, that drag will not be lower on the way down, which means the terminal velocity has to be lower.
The only exception is if the impact site is lower than you, and the nozzle speed is is extremely low. That's never going to be the case for a gun.

Of course, the less mass, the higher effect the drag will have for any given shape. So the smaller the shots, the lower the terminal velocity will be. But it will always be far lower than the muzzle velocity.

Comment Re:This is just the looong tail of the distributio (Score 1) 122

Considering there's an infinite number of prime numbers, and only one of them is even, you could argue that statistically speaking every prime number is odd.

You could argue that, but not in a theorem.
All your axioms must be rock solid, the premises unambiguous, and lead to a proof.

Of course, if this had been a case of forgetting that 2 was a prime, the theorem could have started with "let p be an odd prime...". But it wasn't - the GP only used that as an example.

You are aware that your projectiles don't go into orbit? Those come down at the same speed, about, that you imparted when you shot at the socialist ISIS pedo spy drone - and if you missed. Firing into the sky is the same as firing randomly into a crowd.

You seem to be unaware of friction, in this case drag (air resistance).

If you shoot a shotgun where the payload reaches X feet up into the air before stopping and falling down, they will have the same airspeed as if you dropped them from that height. And due to air resistance that's not much - about the same as hail, for the same reasons.
Being peppered with falling shots is a common enough experience for hunters. It doesn't even hurt.

If it's the same David Boggs, KY, age approximately 40 that I googled, he appears to have a history of dishonesty.

If it's the same guy, he first got kicked out as a minister of his church for having an affair with a younger woman and then lying about it. Then arrested for abduction of their children after she won custody. And a few more things, but those would be hearsay.

Windows has a setting to enable ASLR for all applications. Microsoft even provides a handy tool to enable it; the, "Enhanced Mitigation Experience Toolkit". No special compile time gesticulations are required.

But it's not the default. And requires either downloading and running extra software, or writing a script to do it. I would call that hand waving.

Anyhow, with 32-bit Windows going away (slowly, but still) there's less excuse not to make it default, with rebasing taking place after every system update. The ~3GB address space for PE32 meant there was an advantage to making sure all the common libs were placed back-to-back. With 64-bit, that's no longer a big concern.

It is literally already implemented in every version of Windows since Vista.

Well, yes and no.
It allows you to change the address for DLLs, but leaves it at a predetermined address by default. You can check this by installing cygwin, and do "rebase -i nameofsome.dll"

This is unlike the "prelink" command for Linux which requires an explicit option, -m, to not randomize.

The more cordial the buyer's secretary, the greater the odds that the competition already has the order.
