The Lunas Are Back!

North Alabama has suffered through a drought the last two years, with last year's being "exceptional". Because of this the local insect populations appear to have had significantly declined. While this means less of the pesty bugs, it also means fewer sightings of the neater ones.

Like I hadn't see a Luna moth here at all in the last couple years, while in prior years there were always some showing up in the spring.

This year, rainwise, has been different. We're basically getting normal rainfall--though technically the drought is not yet broken--and starting to see some critters that I haven't seen for awhile. I was very happy to again see one of the Lunas:



















The big, furry Cecropia moths have managed to show up each year, despite the drought, and this year was no different:


















Cool, eh?

And I don't know what this guy is, but he's certainly pullin' in Shanghai off the shortwave...


















Later this year we should be getting the big "rhinoceros" beetles. Stay tuned...

Binary Search -- Mmmm, tasty!

I stumbled across Tim Bray's article on binary search, and simply felt compelled to pass it along.

It's well-written, concise, and even if as a software developer you've got binary search down pat, it's still a pleasure to read a well-written explanatory article about something so fundamental to our craft.

So if you need a little refresher on the details of binary search, and why it's so gosh darn useful, or you need to roll your own because you need to make some small variations to the basic algorithm (which was my situation and why I went looking for some articles on this subject), give it a read.

Good technical writing stands the test of time.

Send Your Loved Ones Into Space -- And You Too!

A couple of upcoming missions have announced that the public can submit their names, which will then be attached to the spacecraft that is launched into space. I've done this with a couple previous space missions, and it's a cute thing, you can even get a certificate :-)

The two missions that I just became aware of that are doing this are:

Lunar Reconnaissance Orbiter - whose purpose is to "to [find] safe landing sites, locate potential resources, characterize the radiation environment, and demonstrate new technology." Send your name (and those of your family and friends) to the moon!











Kepler Mission - "specifically designed to survey our region of the Milky Way galaxy to detect and characterize hundreds of Earth-size and smaller planets in or near the habitable zone." Submit your name (and a brief message if you want) to be carried along on the spacecraft that may be the first to detect a possibly habitable extra-solar planet.
