It looks like more companies are buying new computers with Linux installed than installing Linux on old computers. This is really important because it shows that Linux has become more of a "testing" operating system. Companies are actually planing to have their servers running Linux.

On Red Hat’s earnings conference call Tuesday CFO Charlie Peters noted that "the Windows market continues to be something that we're definitely going after and something we’ve made good progress on."

Red Hat CEO Jim Whitehurst explained the dynamic.

Typically you don’t get a situation where somebody has a Windows box and comes in and reinstalls Linux on top of it or vice versa. The competitive dynamic happens with new infrastructure coming in or new workloads coming in, new applications coming in. And so working well with, making the SAPs of the world or the Accentures of the world, or ensuring web applications are built on a LAMP stack. That’s really where the battle happens. The typical field of battle is actually who’s getting the incremental 500 servers of infrastructure at XYZ company. And that’s again certainly the OS is important, but it’s also ensuring that the applications run best on that, that the tooling is there, that the company has the skill set to manage. I think we do incredibly well there. And obviously it’s one of the reasons you’ve seen the growth.

In this model, the universe is a kind of cosmic Russian Doll, with all previous universes contained within the current one.

That's an extraordinary discovery: evidence of something that occurred before the (conventional) Big Bang.

Today, another group says they've found something else in the echo of the Big Bang. These guys start with a different model of the universe called eternal inflation. In this way of thinking, the universe we see is merely a bubble in a much larger cosmos. This cosmos is filled with other bubbles, all of which are other universes where the laws of physics may be dramatically different to ours.

Hopefully this will improve airline food.

One of the most recent noise-reducing technologies shepherded through the research process by NASA and now making a difference on commercial jet engines is chevrons.

Chevrons are the sawtooth pattern seen on the trailing edges of some jet engine nozzles. As hot air from the engine core mixes with cooler air blowing through the engine fan, the shaped edges serve to smooth the mixing, which reduces turbulence that creates noise.
