In order to use the .send({from: ...}) method, you need to

• Have the from account unlocked on your provider.

  OR

• Add its private key to the web3 account wallet (docs)

Ulocked provider account

This approach is mostly used on local providers (e.g. Ganache) that fund and unlock some accounts by default.

Keeping an unlocked account on a production provider is unwise, because anyone who queries the provider can send transactions.

You need to pass the private key that generates the from address.

It's the way you walk the trees. You're not correctly identifying the parent node during your scan. As far as I can see, it has nothing to do with the parse (and hence packcc), and the results and the code I present below were created without using packcc or the grammar at all; I just created a few trees by hand using your node function. That's usually a better way to debug, as well as being a better way to create minimal examples, because it helps clarify what is irrelevant to the problem (in this case, the parser, which is quite a lot of irrelevant code).

Here's what your function produces, with the correct lines on the right (produced with diff --side-by-side so that you can see the differences):

Most of this is not related to the token code and is an economics topic. Which is offtopic here at StackOverflow, so I'm just going to briefly say something that is only partially correct: As long as there's enough buyers and sellers willing to buy/sell the token for the price of gold, the token is going to have a price of gold.

However, you can define functions in your contract that control its total supply, which affects the price (sometimes affects the price - economics again).

Take a look at the PAXG source code:

1. Negative look ahead e.g. !Rule, will always return undefined, will fail if the Rule match.
2. The dot . will always match a single character.
3. A sequence Rule1 Rule2 ... will create a list with the results of each rule
4. A repetition Rule+ or Rule* will match Rule as many times as possible and create a list. (+ fails if the first attempt to match rule fails)

Your results are

The "bitwise or operator" aka | has the lowest precedence of regular binary operators. The only binary operators with lower precedence are comparison operators, which are subject to chaining – for example, a < b < c is roughly equivalent to a < b and b < c – and thus behave specially.

For a PEG parser, precedence is usually encoded using precedence climbing. That means a lower precedence clause matches either itself or the next precedence clause. As such, the operator precedence "| < ^ < & < ..." is encoded in a ladder of bitwise or, bitwise xor, bitwise and, and so on:

The source project you're trying to use is a Maven based project and provides instructions on how to include it as a dependency.

1. Create a new Maven project in Eclipse (or update your project to be Maven based, adding a pom.xml file, standard folder structures etc)

2. Edit your pom.xml file and add a dependency to the yahoofinance-api project:

The code was using atol. For Windows cpp long is a 32-bit integer. See https://docs.microsoft.com/en-us/cpp/cpp/data-type-ranges.

This has been fixed by https://github.com/fluent/fluent-bit/pull/3501.

This is true also for Docker running on amd64 CPU, when the image is build for arm64, and the whole mechanism is explained in this SO

The mechanism for emulation is using the information in the elf to recognize the architecture for which the process is build, and if the architecture of the binary differs from the architecture of the CPU, it starts the qemu emulation. Though the recognizing of the architecture is more related to the process, there is still information about the targeted architecture of the docker image. The targeted architecture is determined from the "Architecture" flag on the image which was set when the image was build. Any of the containers that will run the image will be associated (trough the image) with this flag.

It should be noted that the "Architecture" flag on the image will not prevent a single process inside the image, which is compiled for a different architecture than the flagged one to run. The reason for this is that bitfmt (which is the underlying mechanism sitting inside the linux kernel) will always try to recognize the architecture from the magic numbers of the elf and will start the the emulation if the magic number is recognized.

To list the architecture of the containers, you can use the following "quick" query:

The token will be pegged to the USD because you promise to always give back $1 for every token. As long as you keep that promise, and people believe that you will be able to keep that promise for the foreseeable future, it is "pegged". In your example, your promise and reputation within your group of friends should have to be enough to "back" the token. In essence, all stablecoins work like this. They are backed by a company or even a smart contract that uses all sorts of methods to provide users trust that they will always be able to sell their tokens back for the original underlying value.

So if you keep the token circulating among your friends, you should be fine. But if you start using the token outside of this close group, with people you may not even know - the "peg" will start to lose it's value. People don't know you and might not trust you to give back the full 1$.

Be aware that there is no real method of "fixing" a coin to a specific value, at least not without a tremendous effort. Even the Tether (USDT) token fluctuates in price. For a game, you might try to use on of the stablecoins present on your platform.

More importantly, selling cryptocurrency in exchange for dollars or other fiat (normal) currencies is a highly regulated activity, with expensive permits and complicated procedures regarding KYC/AML (Know-your-customer/Anti-money-laundering) so this should not be taken lightly.
