Bocaj writes "I recently spec'd out a large project for our company that included software from Red Hat. It came back from the CIO with everything approved except I have to use CentOS. Why? Because 'it's free Red Hat.' Personally I really like the CentOS project because it puts enterprise class software in the hands of people who might not otherwise afford it. We are not those people. We have money. In fact, I questioned the decision by asking why the CIO was willing to spend money on another very similar project and not this one. The answer was 'because there is no free alternative.' I know this has come up before and I don't want to beat a dead horse, but this is still a very persistent issue. Our CIO is convinced that technical support for any product is worthless. He's willing to spend money on 'one-time' software purchases, but nothing that is an annual subscription. There is data to support that the Red Hat subscription is cheaper that many other up-front paid software products but not CentOS. The only thing it lacks is support, which the CIO doesn't want. Help?"

Phil Plait ("The Bad Astronomer") writes with a skeptical take on the recent report that a comet may have narrowly missed earth. According to the linked post from Plait, "When a comet breaks up, it spreads out. Even when intact, the material surrounding a comet can be tens or even hundreds of thousands of kilometers across! Claiming that a comet broke apart, yet managed to constrain its pieces to volume of space less than a few thousand kilometers across strains credulity. Mind you, Bonilla claimed to have seen these objects over the course of two days. That means they would’ve been stretched out along a path that was a million km long at least, yet so narrow that only one observatory on Earth saw them transit the Sun. That is highly unlikely. Worse, the very fact that no one else saw anything makes this claim even less tenable."
