Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Assign expression-template to variable in C++
Then, each expression should carry enough information that you can call different member functions, such as derivative for their derivative, or conjugate to take its complex conjugate, etc. Now, the conjugate (and derivative) member function should somehow inherit its behaviour from the sub expressionss. You only need to define what conjugate means for the Number class, and then all other expressions, just apply this function to its sub expressions, until a Number is reached. I am not sure if this is detailed enough, but I apply this logic here. In this piece of code, I am using ETs to that define expressions, and then use these expressions to take their derivatives. This is an autodiff library (without dual numbers), which works well, but it suffers from the the problem; can't find a way to assign and reassign variables to expressions.
