Pineapple Tool

On this week's America's Test Kitchen the gadget guy demonstrated a device that cores, peels, and slices pineapples. The Cooks Illustrated review says that using a knife and carving the pineapple manually does yield more fruit (31 vs. 24 ounces of a 64 ounce pineapple), but this gadget makes it incredibly simple. The whole process took less than five minutes, required virtually no skill, and I got a whole bunch of pineapple slices to eat for lunch. According to my nutrition software, a single slice or raw pineapple contains 79% of your daily value of vitamin C, 34% for Manganese, and 5% of your daily fiber. All for less than 2% of your daily calories!

Here in Fairbanks, pineapple isn't exactly cheap (I think it was around $1.90 / pound, which means it's almost $4.00 for a pound of usable fruit), but I think that eating real, fresh food, is worth the money, and adding an occasional pineapple to my diet is a good thing.

Flying Squirrell

I guess I was wrong about the flying squirrel being disturbed by the boreal owl we had last week. The squirrel has been visiting our feeders regularly since, and we've even seen a pair of them on occasion. His eyes are actually black, but they're so large that when the flash hits them, they turn completely red. The photo has been edited so they're white instead.

My wife took the photo. You can see some more of her pictures at her Flickr page.

Boreal Owl

A few days ago we had this little guy show up at the tree nearest to our house. The photo was taken by my wife, standing about four feet away from it. We've got a whole bunch of bird feeders all over the deck, and we think the owl was probably harvesting voles that come out to eat birdseed that makes it to the ground. We often see a flying squirrel occupying the same perch on that tree, but he's been absent for a few days now.

You can see larger versions of the photograph at my wife's Flickr page.

Journal Template

I'm in the process of making a blank journal book and once it's finished I'll want something to guide my writing. A few weeks ago I saw a posting on moleskinerie about a template based on Robert Bringhurst's great book, The Elements of Typographic Style. The link led to Rod Graves' blog, where he had a couple PDF templates for a Moleskine journal book. You put the template behind the page you're writing on, and the lines show through the page, helping you stay on course.

But my journal book is 5.5 inches wide and 8.5 inches tall, and I wanted to be able to customize the line spacing, and the other proportions mentioned in Bringhurst's book. Such things are easy using Metapost, which is a programming language for drawing, and TeX to place the images on the page. I wrapped the whole thing up with a Python script.

For example,

$ make_template.py -w 5.5in -h 8.5in -m 1.618 -x template.pdf

creates a template for the journal book I made, saves it as template.pdf and opens it using xpdf. The program requires Python, a basic TeX installation, and the xpdf program, if you want the tempate to be displayed automatically.

Download make_template.py.

A week ago I posted some data from the Statistical Abstract of the United States. On today's local newscast there was a story about cancer rates in Alaska and one of the people interviewed mentioned that cancer is the leading cause of death in Alaska. In the U.S. heart disease kills 26% more people than cancer. But the numbers for Alaska are quite different than the national averages.

Here's the same table I showed last week, except from 2001, and including Alaska, and Alaska's rank for some causes:

[Cause][National Rate][Alaska Rate][Alaska Rank]
(lower numbers are better)
All causes848.5469.41
Heart disease245.895.21
Cancer194.4108.73
Cerebrovascular57.424.91
Lower respiratory43.223.23
Accidents35.754.446
Motor Vehicle Accidents15.416.3
Diabetes25.112.61
Suicide10.816.145
Homicide7.16.0

The values are deaths per 100,000 residents, so they've already got population size factored in. The Alaska rankings are interpreted such that a low number means Alaska has much lower rates for that cause relative to the rest of the United states. Alaska ranks number one (lowest deaths per capita) overall, and for the individual causes of heart disease, cerebrovascular diseases, and diabetes. And we've got the third lowest death rate due to cancer and lower repiratory diseases. Alaska ranks pretty low (high death rates) for accidental death and suicide, however. The extreme environment and very long winter probably contribute to both of these higher death rates.

So more Alaskas do die from cancer than anything else, but relative to the rest of the United States, we have remarkably low death rates. Perhaps there is something to all the open spaces and the clean air and water that keeps the average Alaskan healthy?
