Never be a prisoner of your past

A mile-wide meteor hit Greenland and was hidden by an ice sheet

The most interesting story for me yesterday was that a mile-wide meteor hit Greenland, possibly as recent as 12,000 years ago, and created an impact crater 19.3 miles wide. The impact would have released 47,000 times the amount of energy that was released by the Little Boy nuclear bomb that was dropped on Hiroshima in 1945. The impact crater was hidden by a half-mile thick sheet of ice until recently. (The image shown comes from the article I linked to.)

Getting a Mac/Java app ready for Apple’s Mac App Store

Over the last two days I’ve gotten a Mac/Java app ready for Apple’s Mac App Store, including bundling the application as a macOS “.app” application bundle, and signing it so it can be submitted to the Store.

A relatively quick look at my browser history shows that I needed to hit over 260 URLs to get that done. As a wise professor once told me, “Keep learning, keep learning.”
