In 2018 we celebrated 20 years of “open source” and the 20-year anniversary of the Open Source Initiative (OSI). On Opensource.com, we were excited to join the celebration with an article by Christine Peterson, who coined the phrase “open source software,” and I think it’s fitting that we kick off the 4th annual Open Source Yearbook.
The past year also saw a lot of changes in open source communities. Diversity and inclusion efforts continued expanding, which is illustrated throughout with articles on how to welcome newcomers, community metrics, how programmers in underrepresented countries can get ahead, gracefully receiving and giving code feedback, and a new film series that highlights women in technology.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
