Not all open source projects are super high profile, but the work you do will help others, hopefully be intellectually stimulating, and likely help your career.

@cassidyjames.com and I will be at #FOSDEM and will be demoing* Osprey in our talk Sunday morning: fosdem.org/2026/schedul...

*Let's be honest, should we really test the wifi and live demo overlords first thing Sunday morning? Probably not. Probably pre-recorded.

There is so much year ahead of us! 🗓️ Which conferences are you most excited to attend? Are you planning a local meetup or organizing your own event?

Let’s fill our calendars together! Drop the events you’re attending or hosting in the comments 👇

"Amplify the members, not just the message"

Open source is built by people, and we want to share the love for the humans building our future 🫶.

Who is an open source contributor or project that inspires you? Tag them below!

- MIT license, nice.
- Built something and shared with others, awesome.
- We don't want to guess your reasons, but we like that you wanted a similar experience to Android copying.

Open source surrounds AI, especially with tools like Gemini CLI. If you write code, learn how to get the most out of Gemini CLI and MCP servers.

Thanks for the shout out. We love open source at Google too. But that is probably obvious.

Sometimes, small bits of knowledge can unlock new ideas.
Have you ever generated a barcode in Python? QR code? What about the other languages you use?

Haven't started contributing to open source yet? Have but would like to be more confident? Or, do you know someone this applies to? Here's a great course by @linuxfoundation.org
