Am building a movies App where i have list of posters loaded using TMDB using infinite_scroll_pagination 3.0.1+1 library. First set of data loads good but after scrolling and before loading second set of data i get the following Exception.

I'm trying to construct a simple application to make operations like comparing, adding objects to Hall of Fame list, etc. I'm pretty sure the Owner class is built correctly, but when feeding the HallOfFame objects with Owner objects, I get many errors.

The app looks like this so far:

I am coding in R and due to stability purposes when I have to deploy something, I call every function with the syntax package::function(arguments) just to avoid conflicts that as you know may happen when using a lot of packages. It helped me a lot over the years.

I know that if is a reserved word so technically speaking it is impossible (or at least it should be in my knowledge) for someone to define an object and name it if.

I am also aware that it belongs to control flow statement (which I think are a different "thing") and due to the previous consideration I am also aware that the following questions might be useless. My pure technical doubts are:

1. Why if I embrace it in back-ticks the function class returns "function" as a result?
2. Why without back-ticks I get an error? and last but most important
3. Why I am unable to access it via the usual base::if() syntax?

As I said, most likely useless questions but at this point I am curious about the details underneath it.

I have a data object that I want to put in URL API to fetch it using Axios, I've done my research but I didn't found any solution to convert this to an Url endpoint

This is simply my data objects :

I have read that toPromise() is being deprecated in RxJS 7 and will be removed in RxJS 8. I have often used it with async await syntax in angular to handle http calls. Is it considered an anti pattern? I understand the concept of streams but an http call only emit a single value. I don't get the point of observable for a simple http call. What should I use next? should I fully embrace reactive programming?

I'm making a simple performance test using SpriteKit where I create thousands of SKSpriteNodes, 50 by 50 pixels in size, no texture and rotate them using SKAction.rotate(byAngle:) and remove them on collision with an other SKSpriteNode that follow the position of the mouse.

For collision and contact I don't use SKPhysicsBody because it is very heavy on performance, instead inside the update method I use a For loop to compare the position of all sprite nodes agains the one follow the mouse.

I'm getting decent performance, I can maintain 60 FPS while having 17k sprite nodes on the screen. However, my problem is that with other frameworks using OpenGL and Vulkan for rendering I'm getting much better results in a similar scenario where I can maintain 60 FPS with 30k sprites on the screen. Since Apple embrace Metal and SpriteKit meant to be really fast, I was expecting SpriteKit to be the fastest in this simple experiment and wondering if it something I did wrong.

I did look in to how to optimise performance in SpriteKit and the only relevant information I've found was to set ignoreSiblingOrder property of skView to true to batch render sprites with the same zPosition. It did help and the FPS went from 40 to 60 with 17k sprites on the screen. This is where I am right now.

I could not find any other information that I could use. I suspect I could improve the way I compare position of sprites inside the update method but I'm not sure what options are there if any. This is how the code looks like:

I create todoapp and I would like to create a button that, when clicked, will modify the list to display only completed tasks. I have three components: App.js - it's a main component, TasksList.js - is responsible for displaying tasks(initially it displays all tasks), ListHandler- I want to create the aforementioned button here. I decided to use useRef to be able to access the list of tasks (ul with class tasksWrapper in TasksList) anywhere. App.js:

Goal: To implement into my exit intent popup code a php cookie for 1 day.

I have found a working way for the popup, and a possible solution for the php cookie. I am very new in php though and having a hard time to piece everything together. I don't use dependencies like jQuery but embrace some lines of javascript.

1. Is the below the right way for the cookie?
2. Is there a way for a SLIMMER code (js, css, php) with the same result?

I have a function perc_diff that I use within dplyr's mutate. It calculates relative differences from the first value in group by default. But it can also work with mean, max, nth or any function that returns one value to compare others too.
