Submission + - ask slashdot, procedural programming to oop

An anonymous reader writes: I have a question that I figured would be best to post to the slashdot community: where can i fnd a tutorial/book that breaks down the concepts behind object oriented programming for someone like me who already has a fair grasp on procedural programming? I don't write code for a living, but with the current state of the job market I wouldn't mind learning more about it in my spare time.

here's what happens: I decide I want to write a simple windows/android application and so I follow a tutorial to get the appropriate development environment up and running, then I follow a tutorial or two and they all seem to just say "then we use this code... to..." without actually saying why im creating a new object, which classes are inheriting others, how to effectively use the gui in the development environment and what code clicking on certain things creates and why.

it just seems like procedural programming is very straightforward and while I realize there are many more aspects to oop, no tutorial manages to explain the concepts in a re-usable manner. I follow a tutorial and either get frustrated that im not really learning anything or I build the application and then realize I could build the same application again but I haven't learned how to look up new classes/objects I might need for a different type of application. the tutorials all get you from point a to b, but they don't really teach you anything. why does oop feel like such a hard area to get into?

Submission + - Time travel may find home in atom smasher (networkworld.com)

coondoggie writes: "So can you slam protons together so hard that the collision creates a particle that can travel forward and backward in time? That, very basically mind you, is the time travel theory Vanderbilt University researchers hope to check out in the Large Hadron Collider — the world's largest atom smasher located in Switzerland (CERN). "Our theory is a long shot, "but it doesn't violate any laws of physics or experimental constraints," said Tom Weiler, one of the physics professors at Vanderbilt University testing the theory"

Submission + - Fukushima - A Simple Explanation 1

Stenchwarrior writes: Along with reliable sources such as the IAEA and WNN updates, there is an incredible amount of misinformation and hyperbole flying around the internet and media right now about the Fukushima nuclear reactor situation. In the BNC post Discussion Thread – Japanese nuclear reactors and the 11 March 2011 earthquake (and in the many comments that attend the top post), a lot of technical detail is provided, as well as regular updates. But what about a layman’s summary? How do most people get a grasp on what is happening, why, and what the consequences will be?
