is it worth it to make a class polymorphic just because of one only among many other of its method is needed to behave differently depending on the data type?

Runtime polymorphism starts to provide undeniable net value when the class hierarchy is deep, or may grow arbitrarily in future. So, if this code is just used in the private implementation of a small library you're writing, start with what's more efficient if you have real reason to care about efficiency (type_ and if), then it's not much work to change it later anyway. If lots of client code may start to depend your choices here though, making it difficult to change later, and there's some prospect of further versions of someMethod() being needed, it's probably better to start with the virtual dispatch approach.

Is there any better approach?

Again - what's "better" takes shape at scale and depends on how the code is depended upon, updated etc.. Other possible approaches include using a std::variant, or even a std::any object, function pointers....

You can take advantage of the fact that if A is a matrix of shape (M, N), and b is a vector of shape (N, 1), then A.b equals a vector c of shape (M, 1).

A row x_c in c = sum((x_A, a row in A) * b).

As a rule, if you have a recursive data structure, a recursive program is worth considering. That way, the code never needs to know how deep in the data structure it is.

You'll need a couple of ingredients:

• A way to store the state of the currently active view
• A way to communicate the state between your menu and main content view

For the first one, I made an enum that listed the different types of views (ViewType) and added it to your MenuItem model.

For the second, you can pass state via a @Binding from parent to child views and back up the chain.

The short answer is you don't.

The slightly longer answer is:

You can place a switch node after the inject node that can be used to gate the output based on a condition, which can include the state of a context variable. How you change that context variable is up to you, but another inject node and a Change node is probably the simplest.

It is not possible to hide duplicates in the Finder search because there is no option for filtering duplicates in the Finder search.

But your job is to search, then create a playlist. This can be done by dragging and dropping your selection onto the next droplet, which you can call "VLC Playlist Creator". (Or turn it into a "Make VLC Playlist" service using Automator). It will filter for you the duplicates and open Save Playlist Dialog of VLC.app.

Controller endpoint mapping needs to be done in order of most specific to least specific.

What's happening here is that the first ('default') route is being matched, and .NET is looking for a class called 'OnwhiteController' - which doesn't exist. It's not even reaching the 'onwhite' route definition.

What you need is to define a custom pattern - 'onwhite' - and specify which controller and action need to be used to display that page.

There is a simple solution to this problem:

Do not use Pixel 5 for development, at least until Google resolves its problems getting it to work properly when connecting to computers, adb, Android Studio, and other applications that require a USB connection. In fact, do not use the Pixel 5 for anything other than for phone calls, connecting to some Bluetooth devices (it doesn't consistently communicate with all of them), and for Wifi connections.

I have returned my Pixel 5 and have replaced it with a phone that I know works properly when connected to USB devices. Until I see some people this year successfully using its USB connection, I won't even consider purchasing this phone again. Actually, I may not ever look at this phone again, considering how poor the tech support is from Google and how little accurate info there is on how to solve problems like the one I presented here.

update() trigger function , returns true if the column is updated even if with the same value. so seems like when you update password, you are updating User_fullname column and other columns probably (with the same value as before of course) . so UPDATE (User_fullname) returns true .

But, also the way you have've written your code , the trigger works for the situation only one column is updated and in that order in your code , for example if UPDATE (User_fullname) is true , your code doesn't check other conditions , because of ELSE IF. you might wanna remove else and check for each column , or totally change your strategy to log data inside trigger.

then based on your comment , get rid of all if else and have one single insert statement like so for all columns:
