Should I go ahead and build PillMinder.me?

I've got some flows done for PillMinder.me, but I'm not sure if I should pull the trigger on a CrowdSpring design or just go with a vworker developer?

Decisions...

Why 1,000,000 > 1,000,000 - a note on weird math

So I posted previously about the math behind bit.ly. This brings up a minor point that made me want to post again at 5:30am today.

When we talk about numbers, the number 1000000 is pretty big.  But the number 0000000 is pretty small.  However, the number 0 is the same numerically as 0000000.  But in a database they are different, if the field is a non-numeric field.

This means that the actual number of outcomes that comprise all the possible combinations from 0 to 0000000 is greater than 1000000.   If you have a single digit number, the possible number of outcomes is 10 (0,1,2,3,4,5,6,7,8,9).  If you have a two digit number, the possible number of outcomes is 100 (01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, ...)  If you consider "6" different than "06" then the actual possible number of outcomes is 110 with a two digit number.

So with an 8 digit number, the possible number of outcomes is as follows:


And this is why 1,000,000 can be greater than 1,000,000.
