July 4, 2008
Using the official date of July 4th, even though the original document itself wasn't signed by everybody until August, this is the United States of America's 232nd birthday. Or the 0503rd, or the 0x143rd, or the 0b101000011st, depending on your preferred numerical base.
Likewise, I have a friend who turns 0x21 tomorrow. I doubt this person would feel the need to take a redo on turning 21, though. Still: Happy birthday!
But anyway, getting back to the original topic of Independence Day: Take a moment to reflect on the principles this country was founded on as you shuffle between cookouts and baseball games and fireworks shows. Then think about maybe electing someone in the fall who might actually believe in them himself.
