QUESTION
I would like to have your opinions by contribution to these two implementations of a TODO List application as to the respect of the principles of object-oriented programming.
Solution 1 : geting corresponding todoList Objet via TodoListRepository and Add TodoItem via the getting Object
...ANSWER
Answered 2022-Feb-22 at 19:05Your classes TodoItem and TodoList are fairly simple and have one responsibility (Single responsibility Principle).
And these classes do not have any code that can pollute their single responsibility. I mean there is no logic for logging or other responsibilities in these classes. So it is okay. Read another great post about Single Responsibility Principle.
But it looks like your code in solution 1 will not save any items as your item will be added to IReadOnlyList Items.
I like that repository has great separation of concerns. I mean that repository is here like simple collection of items. We can make analogy with List, that
List does not have Save() method. Responsibility of saving item is delegated to _unitOfWork. And this is also great separation of concerns.

I have a long list json_response containing Twitter data. Some of the 293 elements in the list do not contain any tweets indicated by 'result_count': 0 and I want to delete those elements from json_response

Answered 2021-Oct-26 at 14:48It is a bit hard to tell what you are looking for but potential versions for a custom column formula are
= if [quantitée facturée]=1 and [quantité retournée]=1 then 1 else 0
= if [quantitée facturée]=1 or [quantité retournée]=1 then 1 else 0
= if [quantitée facturée] = [quantité retournée] then 1 else 0
= if [quantitée facturée] <> [quantité retournée] then 1 else 0
QUESTION
I am not using any Firebase or Youtube code/libraries in my project. Yet recently, in Android Pre-Release Reports I am seeing crashes with this:
...ANSWER
Answered 2020-Nov-06 at 19:34For me, this was happening because I deleted a class, but forgot to remove a reference to it in AndroidManifest.xml.
Go through your AndroidManifest.xml and make sure it doesn't reference any non-existent classes, they will likely show as red, but surprisingly the project will still build.
The name is likely showing as aewt because of build minification / obfuscation. I have absolutely no idea why the error message references youtube, it does for me too when I don't use youtube in the app.
The crash log in the pre-release report was totally useless, but a crash log in firebase crashlytics revealed the source of the issue.
I'm still waiting for a pre-release report to undoubtedly confirm, which I'll have later today, but it seems highly likely based on the firebase crashlytics report and the circumstances.
Edit: My pre-release report is no longer showing this error and is totally passing after removing the hanging reference from the androidmanifest.xml
QUESTION
How can I display the list (RecyclerView) in the order of the most user’s location (one point), by calculating the distance of each item from the location and user? As you can see on my code, while browsing the json, I calculate the distance but each time the user changes position, the list increments with the same data
Note that: If the user's position changes, what must be done to update the list?
And here is my code :
...ANSWER
Answered 2020-Nov-01 at 07:16You need to separate the population of markerObjList and location change listener. In 'onResponse' method only populate the markerObject list.
create the location change listener in separate method say onCreate of view and when location listener is triggered, recalculate the distances for all marker object, sort the list based on updated distance and set the sorted list to adapter. The code will look something like this

Y'all, I'm trying to alleviate some of my work in migrating from a face-to-face teaching environment to one that is remote for at least the next three months. To this end, I am trying to create randomized lists of eligible vocabulary words for quizzes. I can have it generate up to eighteen sets of words for an identical number of quizzes, but I seem to be fumbling with checking whether the randomly selected word is already part of that quiz, i.e. I am getting a ton of repeats. Since one word is taught per day, this means the first biweekly quiz will have ten eligible words; the second, twenty words; the third, thirty words; etc. Please see the code below, and thank you in advance for your help!
...ANSWER
Answered 2020-Aug-21 at 01:31You probably want to try using random.sample(all_words, 10) and loop over to extend the output for subsequent weeks (changing 10 to the desired number of words). You will need to import random first.
