How can I time a code segment for testing performance with Pythons timeit?
...1 = time.time()
total = t1-t0
This method is not as exact as timeit (it does not average several runs) but it is straightforward.
time.time() (in Windows and Linux) and time.clock() (in Linux) are not precise enough for fast functions (you get total = 0). In this case or if you want to average ...
Advantages of Antlr (versus say, lex/yacc/bison) [closed]
...ce. These are errors that Bison catches when generating the parser, so it doesn't affect the end-user experience, but it can make the development process a bit more interesting. ANTLR is generally considered to be easier to use than YACC/Bison for precisely this reason.

!==! is not an opera...
Custom Python list sorting

@HelloGoodbye sort() doesn't have a cmp argument in Python 3. This is an old answer when the docs link was for Python 2. You can find the old docs here or read more about it here. If you're using Python 3, use the key argument instead.

How to convert a std::string to const char* or char*?
...art pointer goes
// out of scope
std::vector
This is the standard way (does not require any external library). You use std::vector, which completely manages the memory for you.
std::string str;
std::vector<char> writable(str.begin(), str.end());
writable.push_back('\0');
// get the char*...

That's just nasty... (I've just tried it, and it does work. But please, please don't do this. Oh, and you can declare dog using var of course.)
Of course you could write an extension method:
