[sdiy] Programming Language Recommendation

[Jason Tribbeck]

That sort of reminds me of a friend of mine who was using a CPU (and
compiler) whose NULL address was 0x80000000.

Caused no end of trouble when porting code from programmers who instead of
comparing a pointer with NULL just checked it against zero...

I.e. they did this:

if (my_pointer) address_is_valid();

Instead of:

if (my_pointer != NULL) address_is_valid();
