"Coding is free" except for the $2000 laptop, the thousands of people working for pennies to make it, the military required to project enough power to keep them working, the endless supply of Starbucks to power through the coding process, the thousands of people working for pennies to grow that, and the military required to project enough power to keep them working as well.

Free otherwise though.

Off-topic and flamebait much?
