base64 encoded images in email signatures
... email clients. For email purposes be sure to read Shadow2531's answer.
Base-64 data is legal in an img tag and I believe your question is how to properly insert such an image tag.
You can use an online tool or a few lines of code to generate the base 64 string.

How do I implement interfaces in python?
... several uses for interfaces. Some of them are covered by Pythons Abstract Base Classes, introduced in Python 2.6. They are useful, if you want to make base classes that cannot be instantiated, but provide a specific interface or part of an implementation.

Initialize parent's protected members with initialization list (C++)
...you describe. You'll have to add a constructor (could be protected) to the base class to forward it along. Something like:
class Parent

{}
std::string something;
}
class Child : public Parent

Expand a random range from 1–5 to 1–7
...will run in a constant amount of time, since 1/7 is an infinite decimal in base 5. One simple solution would be to use rejection sampling, e.g.:
int i;
do
{
i = 5 * (rand5() - 1) + rand5(); // i is now uniformly random between 1 and 25
} while(i > 21);
// i is now uniformly random between 1...
