I'm not saying you're wrong about being able to select, say, 7.1 - but that's not how the Mohs system works, even if some people occasionally think that it is.
You're wrong in two different ways, which I kind of admire:)
Firstly, you have something that is between 7 and 8, so for arguments sake you call that '7 and a half' (this is regularly done).
Then you take another sample, and that scratches the '7 and a half' pieces, and not the 8, so it's between 7 and a half and 8. But that's a completely different scenario to arbitrarily assigning a '7.7'
There is another method of measuring hardness, the vicker's system which does indeed follow a linear scale, so you could potentially use the vicker's hardness of the specimens to determine an approximate decimal value for the hardness of your chosen sample. But that's completely stupid because the whole POINT of this is to show a relative hardness between two samples, ie to be able to measure it by scratching one piece against another. So my comment stands, the '7.7' value is pulled out of someone's ass and has no scientific merit.
The second problem is you then compare with software revision numbers... which are of course numbers pulled entirely out of someone's ass. And of course, version 5.9 is usually less than version 5.10 etc. so again you have no way of saying 'version 5.5 is about half way between version 5.0 and version 6.0 in features.'
The Mohs scale of hardness is a relative unitless scale comparing things to ten common minerals. There is no '7.7' on this scale. 7 is Quartz and 8 is Topaz. So all you can say with any accuracy is that it is between 7 and 8. Maybe it is closer to Topaz in hardness than Quartz, but even so, there's no way of calculating a '7.7' so they just pulled that number out of their ass...
Which makes me wonder how accurate the rest of what they say is.
Too many people want to get rich by selling apps and expect Apple to pay for the marketing of their apps for free on the App Store.
The App Store serves one purpose - not to promote your apps, but to make money for Apple.
If you want to go into business selling an app for iOS then you need to have some plan in place to market it. That doesn't mean sticking it on the App Store and hoping for the best.
If you can't afford to market your app (either by paying for advertising somewhere or just physically spending your own time promoting it) then you really shouldn't waste money or time to develop it either.

When the only jobs for Pascal programmers are teaching other people how to program in Pascal, you know there's a problem.
Sorry :)
You have interesting ideas for sure. Have you considered making a long, rambling and alarmist youtube video?
Thank you slashdot!
Advertising is marketing. But not all marketing is advertising.
For example, how did you learn about adblock?

I'd be pretty cnocerned about them too.
Don't you accept Unicode Pounds over there?
for $5!
Square will have to do what PayPal Here does in territories with Chip and Pin, and that's replace their device with one that has a chip reader.
Of course, the PayPal Here reader with Chip and Pin is almost ten times the cost of the US PayPal Here swipe reader.

Actually, that reminds me, I was meaning to ask on Slashdot if anyone has any advice as to which is the better editor, Vi or Emacs.
I'd love to know.
The document estimates that between 3% and 11% of the Yahoo webcam imagery harvested by GCHQ contains "undesirable nudity".
But what percentage was desirable nudity?
Rubbish.

Isn't that obvious?
Bring back a mammoth.

Maybe a bit overdramatic - but the truth is that overpopulation is every bit as much of a problem as climate change - if not more so.
One could argue these two problems may eventually even each other out - but I wouldn't like to think of that as any kind of positive solution.
Not really a mystery. M = 1000 in Latin
What size bomb will we need?
I don't know. Can you?
I wonder if "destructive pre-emtive force" means exactly what we initially think.
Perhaps the Russians are hinting of something more subtle, a stuxnet style attack on the systems there.
Of course, I'm not suggesting for one moment they could actually pull it off...
