QUESTION
I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

Sharing Lotto, the largest lottery in Korea, is conducted by selecting 6 different numbers from 1 to 45. The number of sharing lotto can be selected by the buyer himself, but it can also be selected in an "automatic" way that is left to the machine.

QUESTION
I want to create a wordcloud where each line is displayed based on its count/frequency. The wordcloud should not be based on single words but on each sentence. The issue is that if I use wordcloud2, it does not display longer sentences and omits 2 of such sentences from the sample. How can I view all the sentences?

QUESTION
It seems like there are two styles for writing NEAR smart contracts in assembly script
- Bag of functions like Meme Museum
- Singleton style like Lottery.
I was wondering under what circumstance one style is recommended over the other.
When should you use one over the other? What are the advantages/disadvantages of each style?
...ANSWER
Answered 2021-May-04 at 17:27The big differences is in initialization of the contract.
Bag of Functions (BoF)For the first style, usually a persistent collection is declared at the top level. All top level code in each file is placed into a function and one start function calls each. The Wasm binary format allows to specify the start function so that anytime the binary is instantiated (e.i. loaded by a runtime) that function is called before any exported functions can be called.
For persistent collections this means allocating the objects, but no data is required from storage, until something is read, including the length or size of the collection.
SingletonA top level instance of the contract is declared. Then storage is checked for the "STATE" key, which contains the state of the instance. If it is present storage is read and the instance is deserialized from storage. Then each "method" of the contract is an exported function that uses the global instance, e.g. instance.method(...)
, passing the arguments to the method. If the method is decorated with @mutateState
then the instance is written back to storage after the method call.
Singleton's provide a nice interface for the contract and is generally easier to understand. However, since you are reading from storage at every method call, it can be more expensive.
The other advantage of the BoF is it's easier to extend as you can export more functions from a dependency.
However, it's also possible to use a combination of both as well.
So really it's whatever makes sense to you.

Answered 2021-May-04 at 11:34Your fault lies in the datatype youre checking. You expect a bool but your are giving it a string.
I assume you want to check if there is a name and not empty?
