Below are the steps required to flash a NextThingCo CHIP or PocketCHIP from the command line, as of November 2018. The web flasher no longer works, and there are numerous errors when flashing from the command line, mostly due to broken dependencies. The following method works for flashing a CHIP as of November 2018:

Note: Flashing must be done on Linux. Tested on Ubuntu and Rasparian. Mac OS seems to not work.

Kata bitshift 28. sept.
Write a function that returns true or false depending on whether its input integer is a leap year or not.
Begin on the top and work your way through the rules.
1. A leap year is divisible by 4.
Ex: 2001 is not a leap year. 1996 is a leap year.
2. .. but leap years are not divisible by 100.
Ex: 1900 is not a leap year.
3. .. unless it's also divisble by 400.
