Ok, so the last time I wrote C++ for a living, std::auto_ptr was all the std lib had available, and boost::shared_ptr was all the rage. I never really looked into the other smart pointer types boost provided. I understand that C++11 now provides some of the types boost came up with, but not all ...

...piece of information, and there can be no duplicate rows. 2NF and 3NF are all about being dependent on the primary key. Recall that a primary key can be made up of multiple columns. As Chris said in his response: The data depends on the key [1NF], the whole key [2NF] and nothing but the key [3NF] ...

... Use range. In Python 2.x it returns a list so all you need is: >>> range(11, 17) [11, 12, 13, 14, 15, 16] In Python 3.x range is a iterator. So, you need to convert it to a list: >>> list(range(11, 17)) [11, 12, 13, 14, 15, 16] Note: The second nu...

So I am having trouble working out what, specifically is the difference between these two. 10 Answers ...

... Because an iterator generally points to a single instance in a collection. Iterable implies that one may obtain an iterator from an object to traverse over its elements - and there's no need to iterate over a single instance, which is what an iterato...

...Remember also that we were reusing a bunch existing code: I'm going to lowball the value of that code at $35,000 giving a total development cost of $200,000. Anyone who's done serious iPhone development can tell you there's a lot of design work involved with any project. We had two designers workin...

...lignment the view is moved to the top. For horizontal alignment this is usually the left-hand side. (But note, that on devices with right-to-left language setting this is the other way around, i.e. right aligned.) Center: The view is centered. End: Usually the view is bottom or right aligned. (On ri...

I'm reviewing some new code. The program has a try and a finally block only. Since the catch block is excluded, how does the try block work if it encounters an exception or anything throwable? Does it just go directly to the finally block? ...

... First of all, floating point values are not "random" in their behavior. Exact comparison can and does make sense in plenty of real-world usages. But if you're going to use floating point you need to be aware of how it works. Erring on...
