In older versions of the Note, you could tap the 4 corners of the screen with the pen, one at a time, to let it auto-calibrate. I don't know for certain that it does anything, but it seems to have helped considerably for me. When I write with the S Pen, I tend to hold it at an angle, like I would a pencil. This resulted in the on-screen cursor being about 1/16" to the left of the actual pen tip, and slightly below. I did the 4-point touches and it seems to have resolved itself - my writing goes where the pen tip actually touches, and the cursor actually shows under the tip of the pen.
as mining becomes harder the essence of a decentralized currency no longer exists as specialized, centralized data centers exist to mine certain coins. Mining is consolidating more towards these data centers, so while it is still decentralized due to number of data centers around the world, it is not as decentralized as it could be should a PoS algorithm be used to validate new transactions
But there is an important distinction between "Faith" and a "predictive model." One is adopted and often unquestioned. The other is adopted pragmatically, for as long as it is productive and useful, and ideally should constantly be evaluated and re-considered.
