What is the best way to solve an Objective-C namespace collision?
...ct (nor is it clear whether it makes any difference). However, there's at least an outside chance that renaming would work. It might be an idea, too, to minimize the difference in the spellings, so that if the symbols are in a sorted order in a table, the renaming doesn't move things out of order....
What is the preferred/idiomatic way to insert into a map?
...<< pMyObj->m_i << std::endl;
return 0;
}
Output (at least for VS2017 and Coliru):
pMyObj was not inserted
pMyObj was modified anyway
As you can see, pMyObj no longer points to the original object. However, if you replace auto [it, b] = myMap2.emplace(0, std::move(pMyOb...

...on your own scripts that have not been downloaded from the Internet (or at least don't contain the UNC metadata), you can force the policy to only run signed sripts. To sign your own scripts, you can follow the instructions on Scott Hanselman's article on Signing PowerShell Scripts.

return h;

On every machine I benchmarked it on, the first was at least as fast as
the second. Somewhat surprisingly, it was sometimes faster (e.g. on a

Disadvantages of Test Driven Development? [closed]
...more code.
So be careful... if you don't have an enthusiastic team and at least one experienced developer who knows how to write good tests and also knows a few things about good architecture, you really have to think twice before going down the TDD road.

Why em instead of px?
...vertising banners, logos or icons. This ensures you almost always need at least some px-based measurements in a design. Images, for example, will (by default) be scaled such that each pixel is 1*px* in size, so if you are designing around an image you'll need px units. It is also very useful for p...
