Tired but happy

Looks like I started work right in time for the deadline crunch. Tuesday and Wednesday nights, I volunteered for some overtime, working until around midnight both times, and I also signed up to work Saturday and Sunday. Haven't had much downtime, but if I put in no more overtime this week, I'll take home quite a chunk of change. And that certainly doesn't suck.

Besides, the overtime work isn't anything challenging — just sitting there making fake drivers' licenses over and over again, to see if I can break anything. Every time I've had an ID picture taken, I've had to fight the urge to make faces (my usual response to seeing a camera). Now I can give in to it. I just wish I could keep some of them as souvenirs, since I've made some really good ones...

I've also started cracking the Florida license number code. I already knew that the two-digit grouping indicates the year of birth, and that the "number" begins with the first letter of the person's last name. To that knowledge, I've added the fact that the first three numbers following the letter are also derived from the last name, and never contain the numerals 7, 8 or 9. For example, reading this very post are people whose licenses almost certainly begin with P510, S512, C425 and P456 (assuming I've figured out the algorithm correctly). But not W425, because he never deigns to read blogs.

So your new job is either working at the DMV or making fake licenses for college kids. Either way, I'm glad you like your new job.
GET OUT OF MY WALLET!
I'm working for the company that got the contract to actually produce the new driver licenses. It's certainly been interesting so far.

The card printers are a technological marvel.

You were right about W425. He was shocked (shocked!) when we told him about the number and your theory.
Got me! I could have told you some of that, my ex was a cop and had told me that years ago.


Sure, you could have, but being told is never quite so satisfying as figuring it out on one's own!

If they're using Soundex, then yours should be L 000. I used to know more, but all I remember is the 7,8, & 9 part, which was the quickest way to spot a fake.
Yup, it looks like it's Soundex all right.

Color my face red; for a CS course in college I'd had to write a program to convert names to both Soundex and Metaphone codes, but I'd completely forgotten about it until you mentioned its name.
