Exploding Trees!

Maple-syrup maker Ryan Tilley braves a forest aflame with exploded maple to tap his trees.
I remember listening to this captivating news report on NPR a couple of years ago, while driving to Robinson, IL from St. Louis, MO airport (work-related travel), on a deserted Rural Route amidst corn fields in the Midwest. The following is an excerpt of this article from Wikipedia.

Exploding trees are phenomena mostly observed in the northeastern United States and Canadian wilderness, and usually involve maple trees. In the Canadian wilderness, maple trees have been known to explode due to the extreme cold which causes the wood to contract, applying tremendous pressure on the sap inside. This often leads to a sound similar to a gunshot when the tree explodes.

A tree may also explode when struck by lightning [1], [2]. The strong electric current is carried mostly by the water-conducting sapwood below the bark, heating it up and boiling the water. The pressure of the steam can make the trunk burst. In Australia, the native eucalyptus trees are also known to explode during bush fires due to the high flammability of vapourised eucalyptus oil produced by the tree naturally. [3] [4]

Now, on a totally unrelated subject, calendar on my desktop is strangely showing a wrong date (see below). This is weird.
And then, easy-to-follow instructions for Google TiSP (BETA) are not making any sense to me. I wonder what is going on. Is it just me?
