This follows a comprehensive study in three parts released today from the National Academies that, for the first time, urges required action from the government to curb climate change."

You may recall last summer when we discussed Heroes of Newerth, a title from S2 Games that's based on the popular Defense of the Ancients mod from Warcraft III. We passed out some closed beta keys, and there seemed to be a ton of interest, in part due to the fact that they have a Linux client. Well, if any of you missed it or want to see how the game has progressed since then, now is your chance — the open beta begins tonight (March 31). There's a countdown on the sign-up page that shows when you can register.

An anonymous reader writes "The Australian Informatics Olympiad programming test is being run in a couple of months. I'm an experienced programmer and I'm thinking of volunteering to tutor interested kids at my children's school to get them ready. There will be children of all levels in the group, from those that can't write 'hello world' in any language, to somewhat experienced programmers. For those starting from scratch, I'm wondering what language to teach them to code in. Accepted languages are C, C++, Pascal, Java, PHP, Python and Visual Basic. I'm leaning towards Python, because it is a powerful language with a simple syntax. However, the test has a run-time CPU seconds limit, so using an interpreted language like Python could put the students at a disadvantage compared to using C. Is it better to teach them something in 2 months that they're likely to be able to code in but possibly run foul of the CPU time limit, or struggle to teach them to code in a more complicated syntax like C/C++ which would however give them the best chance of having a fast solution?"
