This week I wrote an algorithm in Ruby to convert binary numbers into decimal numbers. Here’s the problem description, from Exercism:

“Convert a binary number, represented as a string (e.g. ‘101010’), to its decimal equivalent using first principles. Implement binary to decimal conversion. Given a binary input string, your program should produce a decimal output. The program should handle invalid inputs.”

Project announcement! Last night I built a Markov Chain-generated novel, titled Ceramic Nation.
