hubble | Security Observability for Kubernetes using eBPF | Networking library

I am pretty new to coding. I am learning HTML and CSS. I would like to know how I can make this title and subtitle centered in the four form factors (sizes I precized).

I am not sure why using white-spaceno wrap does not help :(

I am experimenting with std::format_to_n and when I tried to compile example from:

https://en.cppreference.com/w/cpp/utility/format/format_to_n

in VS2019:

I want to list all the full path of the files under a folder and all its subfolders recursively. Is there a way to do it? It seems that if the files go into 2 levels, the code can be written like is,

My index data is

I want one of the parameters i pass to odeint to be a function.

In my case, this is the Hubble constant H which should decrease with H ~ 1/t.

This time "t" is exactly the same time that my odeint uses for solving coupled ODEs. (I want to solve equations of motion in an expanding universe and want H to be determined outside of odeint so to speak)

How do i tell odeint that i want H to be decreasing with each time step that odeint is calculating?

The relevant lines from my code are (Here, H is a constant (H=1) but i want it to be H=1/t):

I'm currently working on the last FreeCodeCamp intermediate algorithm and I'm running into a problem pushing multiple objects into an array. I'm passing the first test which is an argument with a single object inside of an array, but I'm failing the second test where I need to return multiple objects from the array arguments passed into it with three objects. I'm only returning the last object in the array

So, basically i have a JSON file
