unique | Unique , a Java clone of Endgame : Singularity | Game Engine library

In my version of clang and libc++ (near HEAD), this static_assert passes:

In [dcl.struct.bind] 9.6.4, there is definition of structured binding when initializer is a class type with std​::​tuple_­size​::​value properly defined:

... variables are introduced with unique names ri as follows:
S Ui ri = initializer ;
Each vi is the name of an lvalue of type Ti that refers to the object bound to ri; the referenced type is Ti.

My question is why is it necessary to introduce ri, can't we define the identifier vi directly as reference to the result of get(e)?

I've just updated my flutter project packages to be null-safety compliant and now Android Studio wants me to update my project to use the latest version of Kotling Gradle Plugin. Can't see where to change this though. I have tried to change "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" into "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.6.10" but this has no effect.

My build.grade-file looks like this:

I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

I am trying to define a function that takes a data frame or table as input with a specific number of ID columns (e.g., 2 or 3 ID columns), and the remaining columns are NAME1, NAME2, ..., NAMEK (numeric columns). The output should be a data table that consists of the same ID columns as before plus one additional ID column that groups each unique pairwise combination of the column names (NAME1, NAME2, ...). In addition, we must gather the actual values of the numeric columns into two new columns based on the ID column; an example with two ID columns and three numeric columns:

I have a matrix with many rows and columns, of the nature

I am trying to setup a very small GraphQL API using NestJS 8. I installed all required redepndencies from the documentation, but when I start the server, I get this error:

I borrowed the R code from the link and produced the following graph:

Using the same idea, I tried with my data as follows:

Hi I am setting a notification for incoming call with two actions : Answer and Decline . I need to set Green color for Answer action and red for Decline . But i couldnt find a solution.

Here is my code :
