circ | An IRC packaged chrome app | Bot library

I have a json which includes to similar fields:

I am currently plotting temporal scatter plot using the following data (you can use these data to reproduce my plot). Data to be plotted in x-axis is time, specifically datetime.datetime object (tp_pass) while data to be plotted in y-axis is angle between -180 and 180 (azip_pass). Also, they are both numpy.array.

I am trying to write a function that creates a shape according to a specified condition but getting a compilation error.

I have a large three-column dataframe of this form:

I recently started adding graphic charts to a MacOS application I wrote. The first chart is great and I added a second chart where I ran into a fundamental way the code operates that I did not/do not understand. The only reason I ran into this is because in my second chart I used random to draw some bubbles inside confined areas. It works nicely but when I resized the view window a little bit the chart redrew everything and since I was using random the first set of bubbles remained in the screen and the second set were added to the screen. So I made a simple example to illustrate.

I want to use a C++ map of function to execute some subroutines. Since, such a map of function requires to have the same type of input and output for all the mapped functions, while my functions can have different input type, I though I could made all these different types derive from a SuperParentClass.

However, this idea gives me some troubles. It does not compile. Indeed, the compiler capture the derived type and not the parent class. But if you I directly the parent class in my functions, I won't be able to use their specialties inside my functions (so I come for help).

Here is my MWE:

In the following program I was jus t trying to create a simple class for as Circle circ and then tried to inherit a Cylinder from it cylind. I defined several methods to find the perimeter, area and volume of these geometrical objects but I am constantly getting wrong answer. I had spent several painstaking our hour to find the error but I am unable to find it. I am a beginner so I think there might be something I may have missed. Please help.

I am making a series of applications on physics simulations and until now I've done some of them using purely the handy SFML library. Now I want to add some GUI elements to them. I am just a little bit familiar with wxWidgets framework and wxFrames but have no idea how wxDc works, which seems to be at the core of SFML-wxWidgets integration. I will list my queries one by one.

1. My shot at the old tutorial provided by SFML dev webpage: The final code, after correcting for the trivial errors looks like this:

Does circe provide any function to check if an io.circe.Json object is empty?

The Json documentation doesn't report anything about it, while the JsonObject documentation talks about an isEmpty function, but I verified that
