Are email addresses case sensitive?
...probably the best way to go, but I've seen code where the email address is converted to lower case prior to sending. That's not a good idea, since there is a small chance it will not get delivered. So how you treat it depends on what the consequences of error are and what you're doing with the email...
Why use getters and setters/accessors?

Hiding the internal representation of the property while exposing a property using an alternative representation.
Insulating your public interface from change - allowing the public interface to remain constant while the implementation c...
What happens to global and static variables in a shared library when it is dynamically linked?

while (1) vs. while(True) — Why is there a difference (in python 2 bytecode)?
Intrigued by this question about infinite loops in perl: while (1) Vs. for (;;) Is there a speed difference? , I decided to run a similar comparison in python. I expected that the compiler would generate the same byte code for while(True): pass and while(1): pass , but this is actually not the c...
Possible to make labels appear when hovering over a point in matplotlib?

What are some better ways to avoid the do-while(0); hack in C++?
...le useful, is not a silver bullet. When you find yourself about to write a convert-goto-to-RAII class that has no other use, I definitely think you'd be better served just using the "goto-end-of-the-world" idiom people mentioned already.

Writing a compiler in its own language
...ve to parse strings, specifically escape sequences. You will write code to convert \n to the character with the decimal code 10 (and \r to 13, etc).
After that compiler is ready, you will start to reimplement it in C. This process is called "bootstrapping".
The string parsing code will become:
