            How strict is the mvc pattern with model and view interactions?
            Asked 2021-Jun-16 at 01:01
            I am confused about how model and view can interact

            I was making a simple to do app with mvc pattern and I saw an article which said you shouldn't pass the model values directly to the view, which made the project more complex than I thought (I am relatively new to programming and this is the first time I am trying out a design pattern).

            But then later on I talked to someone who said that that is not true and you can send the model data directly to view, he didn't even use classes or some kind of grouping to separate the function he just put them in separate files.

            I was wondering if there is a guideline that I couldn't find or we can do whatever we want as long as they are kind of separated. I would love an article or a guide to read up on as well.

            Since, I am not 100% sure the context in which you are trying to apply the MVC pattern, a good generic explanation of MVC can be found in GoF's 1995 book, Design Patterns: Elements of Reusable Object Oriented Software.

            In the book, they state the following.

            The Model is the application object, the View is its screen presentation, and the Controller defines the way the user interface reacts to user input.

            A more robust explanation can be found from Martin Fowler where he also makes the case for a variation of Model View Controller that uses a Presentation Model.

            If you are referring to Spring MVC then there is some magic that blurs the lines a bit. But in general, you have a controller that represents some screen or an encapsulated piece of functionality that the user (web requests) interact with. The controller serves up responses that are derived from the domain, usually via a Spring Service (i.e. @Service). The domain (Model) doesn't know anything about the View and the View may or may not know anything about the domain.

            Given that, the View should be derived from the Model. But that's not always the case since sometimes how we present things to a screen is not the best logical way to model things in our domain - not to mention, the domain should be presentation agnostic. This leads into Fowler's argument for a Presentation Model, which is a model that belongs to the Presentation.

            I call this a Presentation Model because it's a model that is really designed for and thus part of the presentation layer.

            Microsoft took that idea and ran with it in a variant of MVC called MVVM (Model View ViewModel).

            You can read more about that in Microsoft's documentation on ASP.Net Core.

            So, back to your original question of "Should you pass the model directly to the view?" If you are using MVC then the controller is what provides the interaction. But if you're really asking, "Can you bind your view directly to the model?" If your model has all the stuff you need organized how your view needs it, then sure. And if it's simple enough, maybe that's the way to go. Otherwise, you could go with something like a Presentation Model or MVVM.

            Concurrent Counter Struct with Type Argument in Rust
            Asked 2021-Jun-15 at 23:55

            I was following along with this tutorial on creating a concurrent counter struct for a usize value: ConcurrentCounter. As I understand it, this wrapper struct allows us to mutate our usize value, with more concise syntax, for example:my_counter.increment(1) vs. my_counter.lock().unwrap().increment(1).

            Now in this tutorial our value is of type usize, but what if we wanted to use a f32, i32, or u32 value instead?

            I thought that I could do this with generic type arguments:

            I haven't come across such a ConcurrentCounter library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32, there is a better alternative call: Atomics, definitely worth checking out.

            Nevertheless, your approach of generalizing the ConcurrentCounter is going in a good direction. In the context of operation overloading, std::ops is worth a look. Specifically, you need Add, Sub, and Mul, respectively. Also, you need a Copy bound (alternatively, a Clone would also do). So you were pretty close:

            React Native - Justify Content not Working
            Asked 2021-Jun-15 at 21:59

            I've been struggling with this all over my react-native app, so I set up a very simple example of it in codesandbox which you can view here:

            https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js

            Within the View with the green background, all of the internal views are centered horizontally within their respective spaces as I would expect thanks to the "alignItems: center" style property. I would expect that I could also center them vertically within their spaces by setting "justifyContent: center", but that doesn't seem to work for me.

            Am I fundamentally misunderstanding something?

            Answered 2021-Jun-15 at 21:59

            The problem is that you are not aligning the text within the individual Views. Your example mistakenly aligns the inner View elements within the larger View element rather than aligning the text.

            To center-align the text vertically within their Views you just need to add justifyContent: "center" to those individual three green Views.

            Here's an example: https://codesandbox.io/s/recursing-kirch-n8one?file=/src/App.js:393-417

            To further explain why you were experiencing the issue you did, see this screenshot with boxes outlining the space the elements were taking up on-screen:

            You can see the inner Views are only taking up the needed width of the text elements inside, but are using the max height available to them.

            Because you can't have braces in that context. If you look at cppreference on list initialization, you see that the case inside a ternary operator isn't defined. So it can't be parsed correctly and you get the error you have.

            You are not measuring the elapsed time correctly:

            1. total_send_time measures the duration of the spawn() call, but as the actual task is executed asynchronously, start_in.elapsed() does not give you any information about how much time the task actually takes.

            2. The ran in time, as measured by start.elapsed() is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in the std::thread::sleep()

            3. Last but not least, your time_to_sleep calculation is completely incorrect, because of the issue mentioned in point 1.

            See microsoft/TypeScript#43667 for a canonical answer. This is a design limitation of TypeScript.

            As you might be aware: in TypeScript's structural type system, Child is a subtype of Base even though it is not explicitly declared as such. So every value of type Child is also a value of type Base (although not vice-versa). That means Child | Base is equivalent to Base... although the compiler is not always aggressive about reducing the former to the latter. (Compare this to the behavior with something like "foo" | string, which is always immediately reduced to string by the compiler.)

            Subtype reduction is often desirable, but there are some places where Child | Base's behavior is observably different from Base's, such as excess property checks, IntelliSense hinting, or the sort of unsound type guarding that happens with the in operator. You haven't shown why it matters to you that you are getting a Base as opposed to a Child | Base, but presumably it's one of these observable differences or something like it.

            My advice here is first to think carefully about whether or not you really need this distinction. If so, then you might consider preventing Base from being a subtype of Child, possibly by adding an optional property to it:
