Ludington Daily News Column- January 2012

alt text

For my monthly newspaper column this month, I expanded on the blog post at Scanning the Bar Code. I turned it in on Monday, but am just getting around to this posting.

Here's an excerpt
Did you know you can learn to read bar codes without a machine? It’s true. Each code begins and ends with 101, and has a 01010 in the middle. These lines are longer than the others at the bottom. There are four different line thicknesses, and a sequence of four lines forms a digit from 0 to 9...

I much prefer scanning the bar codes of items one can shop for in the great outdoors. The codes are usually easy to read. In fact, I would wager that you can read almost all of these bar codes without any help at all.
And tomorrow, my weekly column will begin at Mason County Press.
