For those who know Sentry, you know we’ve been giving back to Open Source maintainers since our early days.

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?

Some hackers found a nice surprise under their chairs at DubHacks over the weekend.

Tired of AI responses that ignore your format? 🔒

On today's Prompt Pad, Rosendo shows how to lock your output schema in @GoogleAIStudio so every response comes back exactly how you need it.

@UzerKayat After the promo went viral, we added extra protections to ensure that codes go to genuine participants in our events. We apologize for the inconvenience, and disappointment, and would encourage you to participate in MLH events so that you can be eligible for future offers! (2/2)

[Major League Hacking (MLH) @MLHacks]

@UzerKayat Hey Uzer, sorry you hit our phone verification outage! A flood of new accounts made just for the Cursor promo took it down temporarily. It's fixed now. To claim a code you originally needed a 30-day-old GitHub account, a verified phone, and Global Hack Week registration. (1/2)

[Major League Hacking (MLH) @MLHacks]

Want more @hacktoberfest? There are some great streams happening this week.

Code for Good with DPGA and @Github starts in 20 minutes!
