            A few notes:

            • job callbacks accept exactly one argument of type CallbackContext. Not two.
            • the job_kwargs parameter is used to pass keywoard argument to the APScheduler backend, on which JobQueue is built. The way you're trying to use it doesn't work.
            • if you want to know only the chat_id in the job, you don't have to pass the whole context argument of search_msgs. Just do context.job_queue.run_once(..., context=chat_id,...)
            • if you want to pass both the chat_id and context.args you can e.g. pass them as tuple:

            How to thread a generator
            Asked 2021-Jun-15 at 16:02

            I have a generator object, that loads quite big amount of data and hogs the I/O of the system. The data is too big to fit into memory all at once, hence the use of generator. And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?

            I'm not familiar with Discord bots but I don't think your endHandler will ever run the else if part the way it is because your code is always creating a new dispatcher when it plays the next song, but never sets up a finish handler for it.

            How does Kotlin coroutines manage to schedule all coroutines on the main thread without block it?
            Asked 2021-Jun-15 at 14:51

            I've been experimenting with the Kotlin coroutines in android. I used the following code trying to understand the behavior of it:

            ...

            ANSWER

            Answered 2021-Jun-15 at 14:51

            This is exactly the reason why coroutines were invented and how they differ from threaded concurrency. Coroutines don't block, but suspend (well, they can do both). And "suspend" isn't just another name for "block". When they suspend (e.g. by invoking join()), they effectively free the thread that runs them, so it can do something else somewhere else. And yes, it sounds like something that is technically impossible, because we are in the middle of executing the code of some function and we have to wait there, but well... welcome to coroutines :-)

            You can think of it as the function is being cut into two parts: before join() and after it. First part schedules the background operation and immediately returns. When background operation finishes, it schedules the second part on the main thread. This is not how coroutines works internally (functions aren't really cut, they create continuations), but this is how you can easily imagine them working if you are familiar with executors or event loops.

            delay() is also a suspending function, so it frees the thread running it and schedules execution of the code below it after a specified duration.

            Why this function is called multiple times in Jetpack Compose?
            Asked 2021-Jun-15 at 09:54

            I'm currently trying out Android Compose. I have a Text that shows price of a crypto coin. If a price goes up the color of a text should be green, but if a price goes down it should be red. The function is called when a user clicks a button. The problem is that the function showPrice() is called multiple times (sometimes just once, sometimes 2-4 times). And because of that the user can see the wrong color. What can I do to ensure that it's only called once?

            What can I do to ensure that it's only called once?

            Nothing, that's how it's meant to work. In the View system you would not ask "Why is my view invalidated 3 times?". The framework invalidates (recomposes) the view as it needs, you should not need to know or care when that happens.

            The issue with your code is that your Composable is reading the old value from preferences, that is not how it should work, that value should be provided by the viewmodel as part of the state. Instead of providing just the new price, expose a Data Class that has both the new and old price and then use those 2 values in your composable to determine what color to show, or expose the price and the color to use.

            As thethiny already pointed out, chatmember updates have so associated message: update.message will be None, while update.chat_member will be an instance of ChatMemberUpdated. Note that Message.reply_text is just a shortcut for Bot.send_message(chat_id=message.chat.id, ...), so as long as you have the chat_id you can just use e.g. context.bot.send_message - and you can get that chat_id from ChatMemberUpdated.chat. In fact, you can still use PTBs shortcuts, e.g. update.effective_chat.send_message.

            Please check out the docs of

            as well as the chatmemberbot.py example provided by PTB.

            I don't think MutableState is designed to be used in the ViewModel layer, since it's an observable integrated with the compose runtime. You could create a MutableStateFlow instead and use collectAsState() from the view layer.

            In your case the issue is probably, because of the state is captured in a coroutine invoked outside composition.
