I've been inspired by a question over on Code Review, which boils down to: What is the proper way to authenticate a user without a database?
Would it be the exact same process if you stored credentials in an array, or an XML file, or even just a plain ol' text file?
For example, let's examine t...

Have you ever wondered what happens when you reach 200,000 reputation?
Just ask Jon Skeet.
Apparently, what happens is … you get a painting of unicorns, signed by us, dedicated to you.
Estimated value? Priceless!
Joel and I actually sat down with Mr. Skeet himself to record Stack Overflow podcast #72 during the London leg of DevDays — in the very Google offices pictured here.
