Below is a 2D array that represents movement of an entity over a 2 second period:

I'm trying to make a platformer with a parallax background. I managed the code and also made sure to add .convert. It is running pretty well for the most part, but every now and then there are periodic lag spikes.

I have the terraform file main.tf that used to create AWS resources:

So I've made a selenium bot which iterates through the list of territorial codes and send this codes to a search box into the website which changes the code into the city name which i then scrape in order to get a list of cities in place of list of codes. The problem is that when my for loop iterates through the list there are moments in which it "skips" the commands given and goes straight into the next iteration therefore I am not receiving a full list of cities. Some codes in the list are absent or unfit to pass into the website so I made exceptions for that situations.

I would like to make an animation of TOF-MS spectrometer (time-of-flight mass spectrometry) using the 'for' statement. I am able to make a script which animates the flight of ions inside the tube. This is the script:

I need to show not more than 3 li elements in a ul that can have N li elements. If the ul increase by more than 3 elements, I want to put a scroll.

I seacrhed in Google without an easy solution.

It works fine with this code, but I want to make it fixed to the amount of elements.

I am trying to create a custom control in WPF that is an ItemsControl (with a customizable data template) that supports dragging items from one container to another. The dragging logic is pretty straight forward and I have managed to get that working.

The problem is that I'm trying to show a simple drag adorner (that's essentially a screenshot of the item/datatemplate being dragged). While I have managed to display the adorner and get it to follow the mouse cursor, it is extremely laggy. I have played around with two methods of building the adorner - first one would be attaching a content presenter to my custom adorner; the second would be actually overriding the OnRender method and drawing it myself. Both methods feature really poor performance.

This is how I've implemented my adorner:

I am trying to simulate 3D plane flight. I have an issue with gamma value (Flight-path angle). It gets out of its bounds and then, the simulation stops. The gamma value is being calculated by this equation:

I turned it into this: m.Equation(gamma.dt()==tf*((L*m.cos(Mu)-mass*g*m.cos(gamma))/mass*V))

The target of the simulation is for the plane to reach certain X an Y values(m.Minimize(w*final*(x-pathx)**2) and m.Minimize(w*final*(pathy-y)**2)), while minimizing fuel consumed m.Maximize(0.2*mass*tf*final).

The solver controls gamma value, by controlling lift coefficient Cl, which affects the lift value L, which, in turn, affects gamma value. The equation that calculates lift L value looks like this: m.Equation(L==0.5*Ro*(V**2)*(Cl)*S). But in the end the solver can not control gamma value till the plane gets to its destination.

What could be messing with it?

My code:

I have a script which runs without any problems for several days/weeks. Based on some definitions, I need to restart this entire script. The restart itself is realized with the following line. And this works in most cases without any problems.
