Plus, iostream… yuck. That would create different issues, as some programs that really wanted to explicitly print in decimal such as a calculator offering e. Y2K mitigation was notably harder. Mitch Lindgren December 18, at am Difficult might not be the right term, but at the very least it would be extremely time consuming to go through and update all the old software to use the new format string or the new API or whatever you invented.

Any attempt to force the change by redefining existing behavior would be bound to break things. Don P. December 18, at pm And, if you could change the base of all output numbers, your system would fail catastrophically the first time a program on the system tries to read the numeric text output of any program at all, which happens all the time, especially on Linux. It gets tricky beyond this though. BBA December 17, at pm Today in mundane things that no longer exist: When LaGuardia Airport opened in , its main terminal was miles away, in midtown Manhattan.

This gorgeous Art Deco building across from Grand Central housed airline ticketing and check-in counters, as well as ramps for limos and buses to take passengers to and from the airplanes themselves. The air industry rapidly outgrew this building and two larger and less ornate terminals replaced it. Then full-fledged terminals at airports opened and the city terminals became redundant. Also, traffic, security checkpoints, more people coming from the suburbs, Manhattan becoming a very unpleasant place to go in the late 20th century, etc.

Oh, paper airline tickets. Another mundane thing that no longer exists, but one I actually remember. They were covered in strange abbreviations and when you checked in they would tear off the stub and staple the rest of it to your boarding pass. RavenclawPrefect December 17, at pm I think the paper tickets stick around in some smaller airlines?

More people need to learn to see this distinction clearly and frankly. I love the country although frankly I think it needs a lot of work. A Mustang chassis with a Tesla powertrain… I think the regime needs to go wherever Sun Microsystems went—or maybe Czechoslovakia. Or the Protectorate of England. Or even Theranos. I will continue to meticulously comply with all its rules, orders and commands, of course, as should everyone else. No regime is forever and every regime is best retired according to its own principles.

Thomas Jefferson had a cool line: That whenever any Form of Government becomes destructive of life, liberty and the pursuit of Happiness, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Of course, Jefferson was a racist. There are a lot of both and they are mostly great people—as individuals. My friends keep begging me to flee to Israel. Also, Israel is a foreign country. Neighbors: America is my country. I will flee when they chase me out.

This capital may then be used by the company to generate more production, and more profits from the sale of goods or services. The experiences of the dot. There is a relationship between a share price of stock and the actual value of a company. It is a second-order relationship, the relationship of an expected future value to current value.

However, financial markets are not restricted to stock, but expand in numerous other derivatives of stocks or bonds. Bitcoins, backed by absolutely nothing, are a new advance in remoteness from actual value. Raising stock to build a new semiconductor factory might be productive. Raising stock to invest in Bitcoins, as Bill Gates remarked, is only something a billionaire should attempt. Bitcoins are created as a reward for a computational process known as mining.

They can be exchanged for other currencies, products, and services, although the process is not trivial. Bitcoin has been criticized for its use in illegal transactions, the very large amount of electricity and thus carbon footprint used by mining, price volatility, and thefts from exchanges. Russia has been accused of evading economic boycotts against it by trading in Bitcoin. The large energy requirement to scale up use of Bitcoins will virtually guarantee the mining will be captured by large corporations.

And that is the toughest rebuttal to claims that the decentralized transactions can lead to a post-capitalist new economic system. Crypto advocates point to eliminating bank intermediaries as an advance for freedom because transactions are much harder, at least for now, to regulate.

There is a single Bitcoin ledger, publicly available, and maintained by a mysterious person or group of people using the name Satoshi Nakamoto. The wallet is currently difficult to obtain and use. The ledger is critical because it can be used to verify Bitcoin, a process which currently takes about 10 minutes to complete but depends on the services of other Bitcoin miners.

Mike Roberts adds in-depth details. Double spending is the high-tech incarnation of counterfeiting. In the physical world, probably. In the digital world, probably not. The cost of that activity, alongside moral scruples and the threat of arrest, keeps counterfeiting in check. To fix this, the inventors of Bitcoin designed a system of network interactions, a protocol, that checks each putative Bitcoin transfer against a public ledger called the blockchain.

How Does Mining Work? Listening for Transactions Bitcoin miners connect to the Bitcoin network like telephone operators. Miners use their computers to listen for transaction requests across the entire network and assemble a list of valid transactions. Bitcoins are not sent and received like file attachments in an email. There are no files at all, only assignments of bitcoins made to various public addresses.

Each public address has a matching private key and only the holder of that key is capable of digitally signing a new transaction request. Additionally, the request must have inputs. Inputs are the previous transactions that the sender is using to fund the new transaction. If you previously received five bitcoins from Alice and four from Bob, you can list these inputs to fund a new transaction to Cynthia of up to nine bitcoins in value.

Miners check two things when they hear your request. First they check to make sure that your digital signature proves that you were actually the recipient of those inputs. To perform this second check, miners peak at a public database of all valid past transactions, called the blockchain, to see if those inputs were already used in a transaction or if they are still available.

Copies of this blockchain are stored on the computers of all Bitcoin users that connect to the network. Every few minutes, one miner will be selected to add their personal list, a block, to the official blockchain, thus keeping the public record up to date. A different miner is empowered to write each block, roughly every 10 minutes, and only valid blocks will be accepted by the rest of the mining community.

This signature is a computer generated product of three inputs, 1 the signature of the predecessor block, 2 a list of valid transactions since that predecessor, and 3 a particular random number, called a nonce. To understand it all, we need a bit more information about digital signatures.

At their simplest, hash functions are math equations that take any given input and create a seemingly random output that will always correspond to that particular input. The hash function used by Bitcoin is called SHA
