You cant hack it

It held the long-term promise to provide a brand new means of exchange that would eventually overtake fiat currencies alongside the traditional financial systems and services — courtesy of transparency, security, and privacy in its characteristics. Another promise, however, was also there and it was not as widely noticed as the first one.

This new way to do business was not that novel. Cryptography professors worldwide had been talking about this kind of system for ages, at the level of principles and possibilities.

Yet nobody before Satoshi Nakamoto came up with a way to turn all that cryptographic potential into a practical thing that works in real life. The record is there in the Bitcoin ledger for all to see. There is the next question, of course. You just need to trust the system, and everything will be ok. But can you trust the system? Keep in mind that the information we present here to you applies to every extant blockchain.

But the technology that supports the BTC environment can now be found in many other networks such as Tron or Ethereum to name a couple.

Because they share the same basic informational principles as Bitcoin, all these different networks are also safe, provided that they are large enough and are genuine blockchains. Everything has changed, and the financial world is no exception. There are plenty of investors who are pouring resources into Bitcoin and other cryptocurrencies in a myriad different ways.

The best-known one is pair-trading, which is the same thing as its older, more established cousin of Forex. More and more businesses keep getting attracted to this technology, let alone individuals. The most common blockchain type consists of a digital database that keeps records of some data critical to a given process.

The way a blockchain keeps its data is also different from other paradigms you may already know. It is split into many pieces, known as blocks. Once one block gets filled with data, the network creates a brand new block, appends it to the previous block, and uses the new space to keep writing data. So, the database is a chain of blocks that grows in time. Hence the name of blockchain. This new block is attached at the end of the chain, so the timeline in the database is obvious and irreversible.

This is complex, but that makes decentralization possible because every node has a full exact copy of the whole blockchain , so every actor in the network has the same information.

You can tell which is which because the network assigns a timestamp to every block, so you know exactly which comes before or after. Also, a cryptographic mathematical algorithm calculates hash codes. This is the big question. Scandals have hit the crypto-sphere at times , and when they do, the mainstream media always makes a big song and dances about it. But before you sell all your digital assets out of fear of hackers, stop for a moment and ask yourself this question: was the hack in the news a problem of the security in the blockchain itself , or was it a hack in the centralized, traditional user systems that the exchanges use to manage their user pool?

You need to remember that websites that deal in Bitcoin have been hacked for sure. But Bitcoin itself has never had a security breach of any kind. Not once. Hackers are pretty active against sites like Coinbase, so hacking attempts have only increased in time.

They could be keeping it all for themselves, unmodifiable by anybody who mouses differently. At first glance, before I read the title, I was excited about Hackaday having a article about fried eggs. Custom trackballs interest me. I use a Logitech M trackball. I upgraded from an M in late before the notorious switches in the M failed. Introduced in October supposedly the M has much improved switches — time will tell.

With the advent of affordable 3D printers building custom mice and trackballs became a real thing. Also surface motion sensors became good enough to track resin snooker balls. Here [1] is a whole page on mouse and trackball sensors. Snooker balls are used instead of billiard balls because they are one solid color.

For comparison purposes, at There are trackballs out there that are great to use with balls even bigger than 52mm, and the one on my desk now is something around that size. Smaller ones do clearly have some advantages — like building into smaller packages, being simpler to make than the hollow balls you require as you get bigger — you can use a bowling ball size as a trackball quite comfortably if its built in to the surface, but the balls mass would really be fatiguing to use so you need a nice smooth even hollow sphere to get bigger at some point eventually.

I have used large direct contact trackballs on commercial and military equipment before. Please be kind and respectful to help make the comments section excellent.

The rent that we pay on earth is the work that we do The coach and principal said the education system must look at rewarding teachers who challenge students to think critically and struggle because "struggle is learning.

He affirmed, "we must get mad about what we are doing, because our children need to be engaged before we impart the information. And, we must commit to being innovative; and not do what we have always done, simply because it's what we have always done.

To a soundtrack of applause, he urged school leaders to stand up to their responsibilities as educators; and to begin the revolution by first reflecting on their own roles; as well as, duties to other teachers and students.

That's why we took the oath to be school leaders.
