I write code, lift weights and play games. I also like everything sci-fi.

Vittorio Romeo questions

Getting SFINAE to work with `is_callable` on an overloaded function object
Why are `const` pointers to functions not usable in a constant expression?
clang vs gcc - CTAD of struct deriving from template parameter
2D Spatial partitioning alternatives to spatial hashes and quadtrees
Preventing CMake-generated makefile for optional-header-only library from compiling source files in header-only mode
Bind metafunction: accept both types and template template parameters (accept anything)
Is there any reason standard library implementations do not use asserts when compiling without -DNDEBUG and -O3?
Lambda machine-dependent segmentation-fault (possible compiler bug?)
Capturing generic callable objects in nested lambdas - always forward?
Swapping `std::aligned_storage` instances containing non-trivially-copyable types - undefined behavior?
