At work a request that I get about once per year is to turn a list of IPv4 addresses into a count of IPs by a certain U.S. state. Originally this was done sequentially and took quite a long time to complete. Having recently learned the Go programming language I thought Go would be the perfect tool to parallelize this task and have it execute much more quickly which lead to the creation of Sauron. Sauron is a small Go app which utilizes the GeoIP Database to convert an IP address to a U.S. state and parallelizes the work by creating one worker per CPU core and farming out the IP to U.S. state conversion through channels.
