I have a bezier curve class. Each point on the curve is defined thus:

My code compiles and when I run it and enter a number, then it will output 2 lines of code instead of one. I'm not sure if there is something wrong with my if-statement that is causing it. But I want to know what it causing my program to output 2 lines instead of 1 with if-statements?

I have a Vue Component in .NET Core MVC where I do an Ajax call to get the info to use it in the Vue Component to show information. I tried it out and it was doing great, the problem is when I update the value of the Database, let's say the initial value is 200 if I update to 500, the value just disappears or doesn't update in the Vue Component, but I know that the value is being returned correctly because I've placed some console.logs to show me the output of the value.

Vue component:

I have implemented shadow-mapping, and it works great as long as I use an orthogonal projection (e.g. to have shadows from 'sun')

However, as soon as I switched to a perspective projection for a spotlight, the shadowmap no longer works for me. Even though I use the exact same matrix code for creating my (working) perspective camera projection.

Is there some pitfall with perspective shadow maps that I am not aware of?

This projection matrix (orthogonal) works:

I have a custom hook that has a locale state value by using useState, and I set the initial value from outside props, but when my props changes, my internal state value didn't get updated, in addition I am not quite understanding that, how many instance of custom hook in my component or application lifecycle where each time it's been triggered?

Here is the code example:

I am working on application on which one time saved on firebase and other is current user time. When app start it retrieve firebase time with date and get current user date and find its minutes. But issue is that it calculate exact when date is same mean first date time is 28/03/2020 10:00 and second one is 28/03/2020 11:00. But when date time is like first 27/03/2020 10:00 and second one is 28/03/2020 01:00 then it does not calculate according to date it also again calculate it according to same day and shows 3 hours. If dates too much vary it shows the result in negative sign. I am searching too much but can not found its best solution also on stack-overflow. Most of accepted answers do the same code like me for this problem but nothing work for me.

My code is:

I'm using transclusion in angular to define a fixed view template and define slots for dynamic content.

The component is app-filter-details and its template is:

I am working on updating a large lecacy system, and so I am constrained by what I can and cannot do.

I have a small multi-component Vue-CLI app that will replace multiple heavy jQuery forms. There are instances where there will be multiple instaces of the Vue app on the same page. I need to be able to pass data into each instance and push that data back out. Each instance needs to interact with it's own set of data.

I am currently mouting the app in my main.js file like this...

I'm really new to the world of DevOps and want to dip my toes in the water. That's why I've been trying to set up a simple GitHub Action where my site automatically gets deployed to Firebase when I push to master but something goes wrong during the build phase:
