I don't have a 3D printer, but about 25 years ago, had seen a STL (Stereolithography) printer, which did something called layered manufacturing using a polymer. I guess today's 3D printers are an evolution of these.
Anyway, my footnote mentions about alchemy, which was supposed to have been practiced by our ancient people, but was systematically destroyed over time.
That would actually work with a printer that can print metal objects. The problem still is that that filament, powder or whatever the printer uses contains real gold and probably is more expensive than buying that gold bar in the first place.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
phht, print bitcoins
- nobody really knows what a real one feels like but there's pictures on the net.
1 bitcoin currently at > $7000 (USD). not bad profit for a couple of bucks of metallic printer paste.
take a trip to NY - the capital of fast money greed
how hard would it be to find people dumb enough to buy your bitcoins 'at a discount, say $6000.'
- if they are reluctant show them the pictures on the internet,
- let them bargain you down to $5k
- tell them you need cash because the vending machine is out of change or for a taxi.
this internet has become nothing but fake news.
... time to fix it, time to get back to the fax!
James, for just $15 an hour, and moderate encouragement, will write you a backtracking recursive descent parser suitable for parsing a modern programming language for less than the cost of using a parser generator tool that cannot parse such languages anyway.
James requires downtime for sleep, recreation, and "family"
Even still, James' parser deliverable will be about the same in terms of scheduling as if you were using a generator tool and refining a grammar input spec.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.
But if you need the postfix there is no way around that, you are dealing with two separate values....the initial value and the return value. With prefix the only thing that matters is the return value. You are talking as if they do the same thing only if you choose one it is less efficient, but they don't, they do different things so have different implementations.
