The second edition of Getting Started with Processing is here and it's updated for Processing 3. It's now in full color and there's a new chapter on working with data. The Processing Handbook now has a second edition too. Every chapter has been revised, and new chapters introduce more ways to work with data and geometry. New “synthesis” chapters offer discussions and worked examples of topics such as sketching with code, modularity, and algorithms.

PCD 2020

The Processing Community Day (PCD) initiative is evolving. For 2020, we will offer a mentorship program for PCD Worldwide Organizers who are interested in learning from past community organizers and mentors. The goal is to help a diverse group of organizers launch a PCD in their local communities. Check out the PCD @ Worldwide site to learn more about starting or attending an event in 2020!
