I've written a fair bit of code in pure C, C++, C#, Java and now getting there
in Python.
The difference between C# and Java is fairly minor.
The others have large and significant differences between them. Garbage
collectors or not is huge. Exceptions or not is huge. Dynamic or static typing

I read some articles about setting PYPY_GC_MAX environment variable.
But I can't find how to get current max_heap_size value of minimark.
Please let me know how-to :)

On behalf of the Python development team, I'm very pleased to announce
the fourth and final alpha release of Python 3.4.
This is a preview release, and its use is not recommended for
production settings.
Python 3.4 includes a range of improvements of the 3.x series, including
hundreds of small

At the risk of sounding like a fogey, I actually think I did, at one time, know
the distinctions between "our projects protocol" and "the language proper" for
C++. I read Scott Meyers books on C++ and STL a couple of times each and helped

Hi everyone, I have this program that writes out the name "John" in block
letters. I was just messing around because we were just introduced to turtle a
few weeks ago in class and I'm just getting the hang of it. Before I was using
"goto" a certain angle, but now I'm using "seth" and it's so muc

__new__ is the constructor which to my knowledge you've not mentioned,

Think about it this way. None here really means "not yet initialized". It is a

Unfortunate how? It's a perfect for what I want here ... remember the context
is such that the lazily stored value is always truthy (I assert this elsewhere).
