This is an excellent answer because it focuses on practicality. Hashes are used for things other than security (such as generating cache lookup keys for non-sensitive data or determining if a serialized object has changed). The chance...
Why should I not include cpp files and instead use a header?
... my codebase individually, and somehow link them together afterwards!" An excellent idea, in theory. But what if your program needs to know what's going on in a different file? It's impossible to completely separate your codebase unless you want to run a bunch of tiny tiny .exe files instead.

Stack vs heap allocation of structs in Go, and how they relate to garbage collection
...
Don't worry that myFunction1 output here is different than in peterSO's (excellent) answer. We're obviously running different compilers. Otherwise, see that I modfied myFunction2 to return myStructType rather than *myStructType. The call to runtime.new is gone, which in some cases would be a go...

In practice, what are the main uses for the new “yield from” syntax in Python 3.3?

What is the difference between “JPG” / “JPEG” / “PNG” / “BMP” / “GIF” / “TIFF” Image?
...ally uses this format.
Good for: Nothing really. There isn't anything BMP excels at, or isn't done better by other formats.
GIF - Lossless / Indexed only
GIF uses lossless compression, meaning that you can save the image over and over and never lose any data. The file sizes are much smaller...
