Open source is built on a simple idea: what you learn, you share. 🎃
What's one thing you've learned from contributing that could help the next first-timer?

Was fun mentoring folks and being a judge at Hacktoberfest Hack Day Bengaluru. Loved chatting with people building with open source AI and helping them figure out how their projects could work for end customers. 🥂
I'm mentoring at @hacktoberfest Hack Day Bengaluru on Sunday, 4 October! 🎉
One day, open-source AI, whatever you want to build 🤖
Bring the idea you keep putting off and I'll help you get it to a demo 🛠️
📍 HSR Layout, Bengaluru

Wrapping up an epic Hacktoberfest 2026 at GCU From pitching disaster response solutions on stage to scoring that sweet MLH swag, the open-source energy was absolutely unmatched. Huge shoutout to the Codenix Club and everyone who brought the heat to Hack Day.

Gotta collect 'em all. Show us your Hacktoberfest stickers!
OMG!! I DID IT!! 😭🎉
I'm officially a Hacktoberfest 2026 Completionist! 🏆
16 stickers earned, and it's only October 10!
I've been learning, experimenting with new tools, and building projects I can actually use beyond Hacktoberfest.
This has been such a fun experience! 💜
