Understanding implicit in Scala
...leave the compiler to look for any valid candidate object to pass in every time it comes across a method call that requires an instance of the request. Since you do have a request available, all you need to do is to mark it as implicit.

What is the canonical way to check for errors using the CUDA runtime API?
...
Probably the best way to check for errors in runtime API code is to define an assert style handler function and wrapper macro like this:
#define gpuErrchk(ans) { gpuAssert((ans), __FILE__, __LINE__); }
inline void gpuAssert(cudaError_t code, const char *file, int line, bo...
What is stability in sorting algorithms and why is it important?
...each item having information about destination of the flight and departure time. You first sort the list based on time. We then sort it based on destination. If the second sort is stable we now have all flights bound to same destination together and in increasing order of departure time. If it wasn'...

Argmax of numpy array returning non-flat indices
...
This will iterate the array three times, not only twice. One time to find the maximum, a second time to build the result of ==, and a third time to extract the True values from this result. Note that there might be more than one item equal to the maximum.

What are the differences between Generics in C# and Java… and Templates in C++? [closed]
...piler is just putting List<Person> into the .NET dll file, but at runtime the JIT compiler goes and builds a new set of code, as if you had written a special list class just for containing people - something like ListOfPerson.
The benefit of this is that it makes it really fast. There's no ca...
