Molecular dynamics computations make up a very large proportion of the computer cycles being used in science today. For those of you who remember chemistry and or thermodynamics, you should recall that all of the calculations you made were based on treating the material in question as a homogeneous mass where each part of the mass simply has the average value of the relevant properties. Under average conditions, this tends be adequate most times. But, more and more scientists were running into conditions that would be on the fringes of where they could apply those types of generalizations.

So you have a great business idea for a wonderful IT product or service, and you want to build your high tech startup around it. Having the idea is a great start, but you will have to build an IT solution/service to get your business off the ground; be it a website, software solution, social network, or mobile app. Which programming language to choose to write these IT products is always the question to get the startup going on a reasonable budget. The truth is, you can write a great product in any language, if you know what you are doing. And when users are looking at a great product they really don’t know which language was used to create it, or how much code it took, nor do they care. But when it comes to time and budgets, there are unique situations, like getting a startup off the ground, where the choice of a programming language can make a difference between success or failure.

On Thursday, a Korean court ruled that Apple did not violate three Samsung patents related to messaging services.

The Seoul Central District Court rejected Samsung’s request that Apple should pay 100 million won ($95,000) in damages, as well as a ban on sales of older iPhones and iPads.

I've mentioned geocaching before, but if you've never taken the time to go out and do it, you're really missing out.

You need only a few things to go geocaching:
