Major League Hacking

Say goodbye to clunky, confusing language-learning websites! Imagine a learning companion that speaks your language while teaching you a new one. Check out ABC's of English, an inspiring hackathon project built to make learning English easier for friends and learners around the world. ABC's of English guides users through three levels—from the alphabet, to basic vocabulary, to full sentences. The tool uses ElevenLabs to model accurate pronunciation and give learners feedback on how they actually sound. With Google Translate built right in, learners can study from their native language every step of the way. Projects like this highlight the power of builder culture by breaking down language barriers and making education accessible to everyone. Read more about their build here: https://lnkd.in/eYpx3RPS

Bring your Solana questions!

What makes someone great at developer relations? Usually, a career that refuses to follow a straight line. Laís Carvalho started out designing water dams for arid communities in northeastern Brazil. Now a board member of Python Ireland and organizer across the European Python community, Laís will share the ins and outs of building and scaling a champion’s program on a tight budget. Caelean Barnes, co-founder and CEO of Gauge, has been studying a question most DevRel teams haven't caught up to yet: when Claude Code decides which auth provider to install, why does it pick the one it picks? Caelean will run a live AI visibility program on a real developer brand. Lisa Tagliaferri has written resources on Python, machine learning, and cloud infrastructure that have reached over 45 million developers. Lisa's argument: the best docs and platform adoption work is marketing done honestly, and it's time to stop apologizing for it. Jonathan Murray, co-founder of Backboard.io, has spent his career translating complex systems into decisions people can act on, from medical devices to defense. Jonathan's rule for developer advocates: the goal is not to sound smart, it's to make other people feel smart. Sean Keegan is a former math teacher turned developer advocate who wants to know: are your developers actually learning your platform, or just collecting badges? Sean will show how to escape the gamification trap and build education that turns badge hunters into builders. See them all at DevRelCon NYC this July 22-23. Register at nyc.devrelcon.dev

I am delighted to again be presenting a lightning talk at DevRelCon! I'll be sharing some of my experience using Claude Code to help me document my coding and convert the best parts into blog posts. I hope to see you in NYC!

Say goodbye to realizing you've been zoned out for 20 minutes while you should be studying! Imagine a study companion that predicts when you'll lose focus before it happens. Check out Synapse, an incredible solo hackathon project by Adyasha Mishra designed to support remote learners with real-time biometric monitoring and empathetic AI interventions. Synapse uses your webcam to analyze focus and stress every 2 seconds, with all video processing happening client-side for complete privacy. But it doesn't stop at detection—the tool combines Gemini 2.0 Flash and ElevenLabs voice synthesis to deliver personalized, calming guidance in under 5 seconds. Its adaptive AI learns your unique patterns over time, from your optimal study hours to your subject-specific focus trends, and even offers breathing exercises when stress runs high. Projects like this highlight the power of builder culture by bringing empathy and personalization to remote learning, where students need it most! Explore the build here: https://lnkd.in/eVCTwXHq

Your API should not trust a user ID just because it came in the request body. Your Solana program should not trust an account just because it was passed into an instruction. That is the security mindset behind Arc 12 of #100DaysOfSolana. This week is about security auditing Solana programs through a Web2 lens: penetration testing a production API. Every account is input from the outside world. Every signer is an authority claim. Every missing constraint is a place where your program might believe something it has not proved. Across seven days, you will: Audit an Anchor program for missing validation Check owner, signer, seed, mint, and authority assumptions Harden vulnerable instructions with Anchor constraints Write tests that try to exploit your own code Use fuzzing to find edge cases ordinary tests miss Recreate a real exploit pattern in a controlled environment Publish a practical security checklist for other developers The lesson is simple: Treat accounts like untrusted input until your program has proved otherwise. Arc 12 starts now. Start building: https://lnkd.in/eidssBpD

We want to give a huge shout out to our newsies and two volunteers James Yang and Anish Paleja who helped us get The Daily Context into the hands of the people at the AI Engineer World's Fair. We couldn't have done it without you! ❤️💙💛 📸: Matt Spinetta (1,3,4), Zac Borja (2)

The AI Engineer World's Fair has been a blast! Until next year. ✌️

⏳ 1 week. That's how long you have to grab a seat at the MLH x DigitalOcean AI hackathon in San Francisco, happening the evening of Friday, July 10th through Saturday afternoon, July 11th. If you've been meaning to build something, test an idea, learn a new tool, finally use that hackathon energy for something real — this is it. No experience needed. You'll have mentors on hand, tools like Gradient AI to build with, free food the whole time, and cash prizes for what you ship. Apply now: https://luma.com/MLHandDO Who's in SF and should be there? Tag them 👇

The final print issue of The Daily Context is out today at the AI Engineer World's Fair! It's been a pleasure serving you. If you're there in person, find us to grab a copy. Otherwise, check out the web version at https://dev.to/aie 📸: Zac Borja (1, 2), Matt Spinetta (3)
