What exactly is Spring Framework for? [closed]
...ction which is a pattern that allows building very decoupled systems.
The problem
For example, suppose you need to list the users of the system and thus declare an interface called UserLister:
public interface UserLister {
List<User> getUsers();
}
And maybe an implementation accessing...
How do I specify multiple targets in my podfile for my Xcode project?
I'm using CocoaPods with my Xcode 4 project and I have three targets for my project (the default, one for building a lite version and one for building a demo version). All the targets use the same libraries, but CocoaPods is only adding the static library and search paths to the primary target. My p...
Why is the JVM stack-based and the Dalvik VM register-based?
...ng the code over a slow
network link.
Going with a register-based scheme probably means that Dalvik's code generator doesn't have to work as hard to produce performant code. Running on an extremely register-rich or register-poor architecture would probably handicap Dalvik, but that's not the usual...
Is explicitly closing files important?

What's the difference between HEAD^ and HEAD~ in Git?

<rev>^, e.g. HEAD^, v1.5.1^0
A suffix ^ to a revision parameter means the first parent of that commit object. ^<n> means the nth parent...
What are dictionary view objects?
...(for instance, one can work with a view on the keys in multiple parts of a program instead of recalculating the current list of keys each time they are needed)—note that if the dictionary keys are modified while iterating over the view, how the iterator should behave is not well defined, which can...

I've been building tools (DMS Software Reengineering Toolkit) to do general purpose program manipulation (with language translation being a special case) since 1995, supported by a strong team of computer scientists. DMS provides generic parsing, AST building, symbol tables, c...
