So, I am making something similar to instagram feed using MVVM architecture, coroutines, Jetpack.
I am displaying list of post in recyclerview using paging-3 library. Each post contains the images, likes count, share counts, comments count. Currently, my app is not using caching. So app is only rely on single data source from network.
I am having the problem in implementing the like/unlike functionality using MVVM. When user like or dislike some particular post, i am making network request to backend api with post_id. The api will return the latest likes count from server. And I want to update this like count in that particular post displaying in recyclerview.
But, I don't how to achieve this functionality using MVVM pattern and update that post data in Flow<PagingData>. I can not use viewModel inside RecyclerView.Adapter class for making network request.
So, how to achieve this functionality using MVVM and paging-3.
You can check out Android : Leveraging RecyclerView Effectively with ViewModel blog by Hotstar. Their approach is One ViewModel per RecyclerView item to overcome similar problems.

I am using co-streamer as a streaming server, also plyr as a video player.
In my mind one approach is to get number of views in a specific method and call in ajax with setTimeInterval method.
But there might be some best way or package to do it?
Any good suggestion about approach or package about views count just like youtube?
You have 2 approaches.
Either you can use socket communication and send back number of live user. You will need some kine of identifier i.e Principal Id if talking in terms of Spring In java
Or as you mentioned use some kind of polling to get counts
I want to create a real-time application ( for e.g. a stock market app) in react native.
Currently I don't know any other way other than to use setInterval(), I am fetching data from a third party API.
So is there any way or third party tool available which gives real time data without using setInterval from a REST source?

Streaming Data Updates
You might have noticed that the todos are displaying fine, except you’re unable to view updated todos without refreshing the app. In this final step, we’re going to fit that missing part of the puzzle.
In the previous section, we added an onAllData method for the ReactiveList component. The second parameter of onAllData receives streaming updates which we’re going to utilize to always keep the todos updated. Here’s how the updated onAllData method will look like in components/TodosContainer.js.
Answer to my problem is the below post.

For my project in college I have decided to make an interactive map where, when the user hovers over a country the title of the top song in that country is displayed. I wanted to get that title from Spotify charts.
I have read every single page of the Spotify API guide and I am still confused as to how should I write the query in processing. I have the authorisation code and the OAuth token, but I'm not sure how should I include it in the actual sketch.
I really need all the help I can get, I am very new to this and I will appreciate every bit of advice.
Use a Spotify API Java Wrapper such as this one to handle API requests to Spotify.
Wrappers are external libraries that simplify API interfacing by providing functions that you can call from your code to make API requests. See this webpage for information about including external libraries in Processing sketches if you haven't done this before.
The most-played track per country isn't likely to change during operation of your program so requesting (it seems you've identified the correct API endpoint for this) the top track for each country just once is sufficient. This process could be done in setup(), for example, since it runs once only.
Then it's a matter of storing the data from these requests in some sort of data structure to allow your program to retrieve the most played track of the country that is being hovered over. A HashMap of country name to top track is appropriate, but there are many viable approaches.
We are currently trying to figure out the best possible solution to integrate sylius with our ERP system through a REST api.
What would be the best approach for swapping out the ORM layer and implementing a cached API layer instead?
Many actions like product creation will be disabled since they are managed in a different system so we only need some write actions like (order and payment). All other read actions will go through either elastic search or the API.
Is override every manager and repository the way to go or is there a better solution?
Thanks
i want to develop a site where user selects various videos and site will render a single video containing all videos in a pre-built template.
what would be the way to go about this (in order to create the movie dynamically from site) ?
what would be the server side framework to use ?
can i use after-effects and have site use it to generate such templates (optional - as i have a friend who works with after effects and can create templates) ?
as i am fairly new to the field any additional information is welcomed.
I'm no expert, but I'm pretty sure you can't do what you described.
Rendering a video consumes huge resources (really huge), so a server park that could
handle this is just not worth it.
However, what you can do is to play the selected videos consecutively. That way, no rendering is necessary.
Also, forget about After Effects, for the same reasons described above.
You can achieve what you want by using a new plugin for After Effects called Templater Bot. From Dataclay's site:
Templater Bot is an enterprise solution for custom video on demand. It works as an automated system. Use it to periodically check for incoming data, pull new data in, and render video as a background process. Or use the command line interface to push data in to create new renders. Once your AE project is prepared, use Bot to customize and render it without operating the After Effects user interface. Developers can create front end applications, such as web or mobile apps, that feed data into Templater's data source, offering a collaborative, custom video content creation solution.
