Here are a few cool things I have found during my wanderings over the net lately:
A draft to a paper to be published in Scientific American about the limit of quantum computing.
A blog about cool stuff found on the preprint site for papers on physics stuff.
A blog post about why linux doesn't cut it in the mainstream and an experiment the author is conducting to try to prove his hypothesis (won't be a conclusive experiment, but could give reason to further experiments in sociology :-) )
Solar evidence points to human causes of climate change, take that climate warming by human intervention sceptics! :-)
The most powerful laser ever built.
That all for now.
