Can someone tell me what Strong typing and weak typing means and which one is better?

I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is why it's useful. I keep hearing about its "flexibility" but it seems like it just moves a bunch of compile time checks to runtime, which means more unit tests…

In my current job I'm building a suite of Perl scripts that depend heavily on objects. (using Perl's bless() on a Hash to get as close to OO as possible)
Now, for lack of a better way of putting this, most programmers at my company aren't very smart. Worse, they don't like reading documentation…

Aye it's been done a million times before, but damnit I want to do it again. I'm writing a simple Matrix Library for C++ with the intention of doing it right. I've come across something that's fairly obvious in mathematics, but not so obvious to a strongly typed system -- the fact that a 1x1 matrix…

I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is under what circumstances it would be preferred. It is flexible and readable, but at the expense of more runtime checks and additional required unit testing…

The proponents of functional programming languages assert that functional programming makes it easier to reason about code. Those in favor of statically typed languages say that their compilers catch enough errors to make up for the additional complexity of type systems. But everything I read on these…

Don't confuse this with static vs. dynamic typing!
You all know JavaScripts/PHPs infamous type systems:
PHP example:
echo "123abc"+2; // 125 - the reason for this is explained
// in the PHP docs but still: This hurts
echo "4"+1; // 5 - Oh please
echo "ABC"*5; // 0 - WTF

I'm a front end Flex developer peeking over the wall at html. One of the things I have a hard time with is weak typing in Javascript. I know many developers say they prefer it. How do I stop worrying and learn to love the weak typing? Are there best practices for variable naming that help make var…

PHP, as most of us know, has weak typing. For those who don't, PHP.net says:
PHP does not require (or support) explicit type definition in variable declaration; a variable's type is determined by the context in which the variable is used.
Love it or hate it, PHP re-casts variables on-the-fly…

Can a loosely typed programming language like PHP be really considered object oriented?
I mean, the methods don't have returning types and method parameters has no declared type either.
Doesn't class design require methods to have a return type?
Don't methods signatures have specifically-typed parameters…
