People ask what I eat. Here it is:

The Diet:

Breakfast
• 1 quart of iced tea, prepared the night before and allowed to cool to room temperature before adding ice. (I like to start the day hydrated.)
• 1 cup Uncle Sam Cereal, served with non-fat milk, berries (straw-, black-, rasp-, or blue-), and 1 packet of sucralose.

Lunch
• Salad, prepared before work: Spinach or lettuce, cubed smoked turkey lunch-meat, cheese (reduced-fat feta, cheddar, or blue), nuts (pecans, almond slices, sunflower kernels, or peanuts), sometimes berries, and home-made vinaigrette.
• 1/2 cup unsalted peanuts, mixed with half a box of raisins. (I sometimes make this my mid-morning snack, if I have an opportunity.)
• Two reduced-fat low-moisture Mozzarella string cheese sticks.
• 1 quart of iced tea, left over from breakfast.

Mid-afternoon Snack
• 1/2 cup unsalted peanuts, mixed with the other half of the box of raisins.
• Water.

Dinner
• An identical salad, prepared with lunch that morning.
• Water
• 2 cups of low-cal yogurt (if I’m still hungry).

Because the syntax of the /etc/sudoers file is obscure, I’m noting down here exactly what I’ve done to mine:

root	ALL=(ALL) ALL
%admin ALL=(ALL) ALL
%admin ALL=NOPASSWD: /usr/bin/wodim
%admin ALL=NOPASSWD: /usr/bin/apt-get
%admin ALL=NOPASSWD: /sbin/reboot
%admin ALL=NOPASSWD: /sbin/poweroff

This allows a few commonly used commands to be executed without a password.

“The Deliverator’s car has enough potential energy packed into its batteries to fire a pound of bacon into the Asteroid Belt.”

I did the calculation just now. My 20 gallon gas tank has enough potential energy to put 9 pounds of bacon into the Asteroid Belt.

Rules of the game:

You can change anything you want about the federal tax code, but your changes must be revenue-neutral. No starve-the-beast proposals.

* * *

My suggestion.

–> Let A be the annual income a full-time (40-hour/week) minimum-wage worker would make.

–> Let B be the annual income of the median worker. (50% of Americans make less than him, 50% more.)

–> Let C be the income of the 67-percentile worker. (66.7% of Americans make less than him, 33.3% more.)

Replace current federal taxes with the following:

1) Increase the EITC (earned income tax credit) to a very large level. Make it 0 at zero income, maximum at A, and get down to 0 again at B.

2) Income tax of 50% on all income greater than C, minus philanthropic donations.

3) A huge tax on carbon emissions. On the order of $10 per gallon of gasoline, with an carbon-equivalent tax on coal, diesel, natural gas, etc.

4) A general policy that negative externalities are taxed equal to the indirect cost to society. Carbon emissions are the biggest part of this at the moment, but I like the idea of pollution taxes greater than the cost of totally cleaning up the pollution. And a big tax on non-reusable goods.

* * *

UPDATE: Hey, there’s a website for revenue-neutral carbon taxes!

Saw today that Battlestar Galactica “Razor” was nominated for the 2008 Hugo for Best Dramatic Presentation, Short Form. I wouldn’t call a 104 minute film “short,” even if the abridged version premired on TV before it was released on DVD. I also noticed that I still hadn’t watched it, even though the Netflix DVD was sitting on my desk.

So I watched it. Four nested flashbacks. Yeah, I’d vote for it, were I a voter. Although I did like “Blink.”
