binary

I had one of my favorite text-message conversations ever today with Ryan's cousin Sean. Sean is a PhD sudent in computer science at Iowa State University. He lives with Ryan and I get so excited every time I get to chat with Sean!

Here's our conversation:

Kathleen: Can you write in binary?

Sean: 01111001 01100101 01110011 00100001 (yes!)

Kathleen: Does that mean yes? You are so cool!

Sean: That's a deinite yes, but hex is way more efficient than binary! 79 65 73 21

Kathleen (after consulting Ryan to find out what "hex" was): I can see that! Is that because hex is base 16?

Sean: Yes it's 1000 times better (1000 in binary of course)

Kathleen: You're a genius! I'm so excited to be your cousin!

Sean: Is it official then? Did you set the date?!

Kathleen: I wish! I'll be sure to tell you when it's official! Hopefully sometime next year.
