Here's 2,500 years old unfinished statue in Greece, still in the ancient marble quarry.









Greeks obviously had plans (and technology) to cut and move it.

https://en.wikipedia.org/wiki/Kouros_of_Apollonas

Quote
The Kouros of Apollonas, also called the Colossus of Dionysus, is a 10.7 metre[1] tall unfinished statue of light grey Naxian marble with a weight of around 80 tonnes. It is located in an ancient quarry near Apollonas, a small town in the northern part of Naxos, one of the Cycladic Islands in the Aegean Sea.

The figure is roughly carved, but the body, head with beard and ears and the beginning of the hair are roughly recognisable. The arms have been cut by the stonemasons as rudimentary rectangles and the shaping of the feet had been begun; they are located on a 50 cm high plinth. The unfinished kouros lies in a rough stone slope.

According to Carl Blümel, a sculptor and director of the Pergamonmuseum, Greek quarrying in early times was similar to Egyptian quarrying practice. The rough form of the figure was carved out. The sculptors were especially able to work the sides. They worked layer by layer, creating flat contour areas. So the sculptors never worked on a leg, arm or head individually, but always on the sculpture as a whole and thus the whole figure was at the same stage of completion at each moment.[4] Only after the creation of the rough contour was the figure rounded out. This is all clearly demonstrated by the Kouros of Apollonas.

The sculptors used bronze chisels, which have left numerous holes in the sculpture, which were probably also the result of the use of pickaxes and hammers and would have been smoothed out in the course of the work by the use of finer chisels and gentler blows

The statue, which has an estimated weight of about 80 tonnes,[5] had been cut free from the stone on three sides, but it was not completed. On the back of the Kouros there are 5–8 cm wide keyholes, which are between 32 and 37 cm apart. In the centre, between the back of the kouros and the stone is a rectangular hole with a width of 40 cm, for the insertion of a wooden lifting beam. These recesses are located in the main lifting points of Greek monoliths. This ancient quarrying technique can be detected by traces in numerous places in the quarry, since it was not used in later times.

It's less magical, when you look at unfinished work-in-progress... It's just a lot of hard work.

But they could do it. They were not stupid.

France didn't even know that there ware stars in the sky when those structures have been built  Grin Grin Grin

And when was that exactly? When those structures have been built?

Here, look it up:

Frankly, if the person is standing next to them for scale, the structures are not than impressive:

Machu Picchu is believed to be built starting 1450–1460. Construction appears to date from two great Inca rulers, Pachacutec Inca Yupanqui (1438–1471) and Túpac Inca Yupanqui (1472–1493).

I wouldn't call that ancient.

That's Machu Picchu, and it's not that old.

Notre-Dame de Paris is centuries older than that, believe it or not.

Hagia Sophia is like 1000 years older.

All non-public communications should be encrypted.  Period.

If you only encrypt selected things, then you are red-flagging those things as “something to hide”, leaking what is in practical effect contextual metadata, and inviting targeted attackers to seek specifically the things that you wanted to encrypt.  Oops.



W0rd.

If you don't mind red-flagging yourself as the-guy-who-encrypts-everything, of course...

i am trying to find out how money transfers through banks technically work (ACH, SEPA). I cannot find anything useful, there are just general descriptions but not detailed technical descriptions. what I want to find out is to what level present day money transfers between private consumers or between business and customer are automated/digitized. how do clearing houses work under the hood? how do they receive, control and process transactions? how are their databases connected or are their kept separate? 

i am willing to rain merits for useful info. or even sats. is there a banker here or someone with prime knowledge about this topic?


thank you!

Haha, I just absolutely wouldn't be able to been spotted at such Island, just not that guy...

Dude, even if you're squeaky clean, and they don't have something to blackmail you with... they could still blackmail your boss, or your GF's boss, or your landlord, etc...

Think about it.

https://en.wikipedia.org/wiki/Wall_Street_bombing

Quote
At noon, a horse-drawn wagon passed by lunchtime crowds on Wall Street and stopped across the street from the headquarters of the J.P. Morgan bank at 23 Wall Street, on the Financial District's busiest corner. Inside the wagon, 100 pounds (45 kg) of dynamite with 500 pounds (230 kg) of heavy, cast-iron sash weights exploded in a timer-set detonation, sending the weights tearing through the air. The horse and wagon were blasted into small fragments, but the driver was believed to have left the vehicle and escaped.

The blast killed thirty people immediately, and another ten died later of wounds sustained in the blast.

This is actually what matters. Energy spent and not hash power as so many take as main metric of how secure bitcoin network is. Hash power keep increasing because better and better ASIC miners gets built. But if energy put into securing Bitcoin network stays same that means that no matter how high hash power will go the network is same secure as before.
This is only true if the same technology is available to all the players.

Bitcoin ded in 3 years!


I don't get quantum computers. Why build one? What's the point?
They only talk about destructive purpuses: "with a quantum computer we can break this or that".
If it's only useful as a doomsday device, then stop trying to make one, dammit!

Bitcoiners have less to fear from boating accidents, and more to fear from getting hacked.  It is scary that your Microsoft Windows® machine is just one careless e-mail attachment click away from scrambling all of your data, and sending all of your money to heinous criminals who know how to make money disappear.  Don’t you wish that you had bought a hardware wallet?  Such grief!

Microsoft Windows machine can be perfectly safe. Let's say it's dedicated to run your full node and nothing else.

What hackers can do in such situation?

What e-mail attachments, when you don't have an e-mail client on that machine?

You never launch a browser on that machine. Not once. So no phishing links.

Full node is the only thing that's running, and nothing else. And not as Administrator, of course.




No, the real problem is keeping your stash in one place, no backup copies (out of pure lazyness). Until one day BAM you lost it.

hey Phil where do you get this data from? Can you open source it?  Cool

I work with hourly data from here:
http://data.bitcoinity.org/markets/price_volume/30d/USD/bitstamp?r=hour&t=lb&vu=curr
(see CSV link at right-bottom corner)

If you're interested in older/more complete dataset, there is a huge archive here (bitstampUSD.csv.gz):
http://api.bitcoincharts.com/v1/csv/
I contains every individual trade, ever.

Maybe it's just newly printed brrrr money in HNWI pockets.

They mostly buy stocks with it, but maybe 1% gets converted into bitcoin.
