Apple’s New Mac OS X: And Why I Am Not Buying It

The question with Apple computers is when to upgrade the operating system? Apple releases updates every few years. But, I might have to wait and skip the next one, Mountain Lion. After all, Apple is taking a step backward. xkcd explains:

Radiation…Tastes Like Metallic Tang

It is a mad, mad world out there these days and I suppose this is the point at which we all begin to run around shouting that the sky is falling. Despite all the madness in Libya, the constitutional referendum  in Egypt, the protests in Syria, the election in Haiti, and the president’s overseas trip to Brazil we still have the aftermath of the Sendai earthquake and the subsequent Pacific tsunami. The latter being particularly important because of the damage to the now infamous Fukushima Daiichi nuclear generating station in northeastern Japan.

Fukushima will likely be up there with the three other major nuclear disasters of a power station variety: the Windscale Fire in Cumbria, England; Three Mile Island outside Harrisburg, Pennsylvania; and of course, Chernobyl in the Ukraine (then the Soviet Union). We sometimes have heard the media compare Fukushima as the next great nuclear disaster, but how bad has it really been?

This graphic by XKCD comes to me via my coworker, Brian Morgan, and it breaks down our average exposure to ionising radiation—the bad stuff—from nuclear accidents from Chernobyl to Fukushima to x-ray machines to the natural radioactivity in the soil. Yes, you are likely being irradiated as you read this post.

Radiation is bad. But we will all find better solutions to problems if we keep our fears both in proportion and in check. Fukushima is not good. But it is far, far from the end of the world.
