QUESTION
I had do some transaction in Binance Smart Chain in Binance-Peg BUSD-T and it worked successfully. But after 5 transactions. I face to a problem that said Returned error: transaction underpriced ! This is my code:
ANSWER
Answered 2021-Jun-14 at 16:32The "transaction underpriced" error occurs, when you're trying to replace a transaction and the replacing gas price is too low.
web3.eth.getTransactionCount() only returns the amount of mined transactions. But you can have N (not just one) of transactions that are waiting to be mined with already higher nonce.
Example:
- You have submitted 4 transactions - nonces 1, 2, 3, and 4.
- Transactions 1 and 2 are successfully mined.
getTransactionCount()returns 2- When you're trying to submit another tx with nonce 3 or 4, it's trying to replace the already existing transactions.
Solution:
Use even higher gas price if you want to replace the existing transaction.
Or if you want to submit a new transaction (and not replace the previous), use higher nonce (sum of "successfully mined" + "waiting to be mined" + 1) that your address haven't used.
QUESTION
When setRows() run on an existing GridItem, the generated Form GridItem elements are fine, but the columns in the linked Sheet are reproduced in the next columns. The new columns are duplicates, but with a hidden property that shows that they belong to the Form (so we cannot delete the new columns). What is this property? The old columns are no more belong to the Form. The old columns may have existing values or previous Form responses.
How to prevent this?
The FormApp should handles the sheet Ranges properly, by looking for the existing columns and just adds the real new columns with new array of strings.
How did the Google Forms UI handle this: When we use the Forms UI, we can easily add new rows in GridItem, and the link Sheet will be updated without duplicated columns.
Here is the Form to test, and please create a new linked response-Sheet before running the code:

...ANSWER
Answered 2021-Jun-15 at 09:35The process of manually editing a grid in a form with a linked sheet is as follows:
- You click the input box for the item.
- You update the text.
- The sheet will automatically replace the title of the corresponding column.
However, with Apps Script. The only process available to change a title, is to use the method .setRows or .setColumns. This behaves very differently from the UI. Esentially, it replaces the rows, and so, the linked sheet will generate new columns so as to preserve the previous answers.
It creates new columns because it has no way to know which new title corresponds to the old one.
For example, if you had some rows:
- A
- B
- C
When you get this from Apps Script, you have to first getRows()

Hi I'm just confused that how to transact BEP-20 Token(e.g: Binance-Peg BUSD-T). I have simply transact bnb in Binance Smart Chain with this code:
...ANSWER
Answered 2021-Jun-14 at 08:58In order to use the .send({from: ...}) method, you need to
Have the
fromaccount 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.
Web3 account wallet
You need to pass the private key that generates the from address.

I am wondering if there's a a way to have Google app scripts sort data before writing it to cells. Here's the very basic script I'm working from. It compares my current inventory to a pre-set restock point listed in another cell.
...ANSWER
Answered 2021-Jun-14 at 07:16In order to compare difference value from different column, it will be faster to write all value into array and perform comparison, after that array.sort() function can be used to rearrange the number before write to new column, here is code that you may find it useful:
QUESTION
I have this code I have entered into Remix IDE, as ReceivedEther.sol, a standalone smart contract.
I've transferred 0.02 Ether to the smart contract, using MetaMask.
When I checked the smart contract's balance, it returns 200000000000000000, as expected.
If I try to use the transferEther function, however, and enter a number smaller than this - say, 0.005 ETH, or 50000000000000000 as the amount - it doesn't work using MetaMask.
When MetaMask prompts me it's never for that amount. It's for 0 ETH and 0.00322 gas fee (or whatever the gas is). Basically it always set the amount of ETH at 0 and only charges the fee.
Why can't I transfer an amount of ETH using this function in the Remix IDE with MetaMask?
...ANSWER
Answered 2021-Jun-13 at 21:44Your code sends ETH (stated in the _amount variable) from the smart contract to the _recipient. So it doesn't require any ETH to be sent in order to execute the transferEther() function.
If you want your contract to accept ETH, the function that accepts it (or the general fallback() or receive() function) needs to be marked as payable.

I have searched a lot for this topic and already found some approach but I get some errors I can't find the reason of it.
Idea is to read the keys from the enum with QMetaEnum to fill the strings in a combobox later.
I have already the enum and also setup Q_Object and Q_Enum Macro in the class where the enum is. But I am getting "undefined reference to 'Planet:: metaObject() const'" error message by using the QMetaEnum.
Here is the planet.h

Answered 2021-Jun-11 at 16:05Including QMetaEnum and deriving from QObject usually does the trick:
QUESTION
I have a bme688 sensor (from Pimoroni) connected to a RPI ZERO. I have the PAHO MQTT library so I can send the data to the broker.
If you see code below, in the very last line, I have a "time.sleep(5)". The code below works perfectly well. It takes the readings and sends them via the MQTT. The problem I have is that if I change the time from 5 seconds to 300 seconds (10 minutes), the MQTT does not seem to send the data. The RPI ZERO has the raspbian desktop installed so I ran it using Thonny to see if I get an error but everything works fine with the 300 second delay... but it does not send the data across to the broker.
Any thoughts?
...ANSWER
Answered 2021-Jun-12 at 22:53You are not starting the client network loop or manually calling it.

You probably want to add client.loop_start() after client.connect()

QUESTION
I understand why it's important that all nodes on the Ethereum mainnet must execute any smart contract function call which changes the internal state of the contract or the chain. (For example, transfers from one account to another ec.)
What I'm wondering is, if its true that every node must execute every function called on any smart contract, even if the function doesn't result in a state change.
For example, if an ERC721 smart contract has a function "getName()" which just returns the name of the artwork the NFT represents which is stored in the NFt. Let's say joe connects to the network, and wants executes getName() on a contract. Does that mean that all 9,000 nodes end up spinning cycles executing getName(), even though Joe only needs it to be executed once? Does the gas cost of running "getName()" compensate each of the nodes for the overhead of running "getName()"? If that is true (that every node gets paid) will gas get even more expensive as more nodes join the pool?
Is one of the reasons gas prices are high is because of the inefficiency of every node having to execute every function called on a smart contract, even those that have no effect on state?
If so it would seem to be a very (and perhaps unnecessarily) expensive proposition to execute a computationally intensive but "pure" (no side effects) function on Ethereum, right?
Thanks. apologies for the possibly naive question!
...ANSWER
Answered 2021-Jun-11 at 08:41There's a difference between a transaction (can make state changes - but doesn't need to), and a call (read-only, cannot make state changes).
I'll start with the call simply because it's easier.
When a node performs a call, it executes the contract function that most likely reads from storage, stores to memory, and returns from memory.
