Here’s why you need real users, even while building. I spent time adding lights, beautiful materials, and aesthetic patterns to this 3D block design tool. Then I gave it to my son. He immediately used it like this🤣 Turns out real users may love crashing things more than carefully building them. #vibecoding #replit #3d

For those who are interested in working in EdTech, I need to be honest with you about what you're signing up for. You probably shouldn't apply. EdTech's graveyard is full of brilliant engineers. AltSchool raised $200M and closed. Knewton raised $180M and sold for scraps. 2,148 edtech startups in India shut down in the past five years. They didn't fail because of a lack of technical skill. They failed from mission drift. Here's what working in edtech actually means: You're not building software. You're building a theory of how children learn. - @MitchForest When you're 2 months into the same feature, and it still doesn't work, you won't have the dopamine hits of shipping fast. You'll need something deeper. For the engineers who build learning apps for @AlphaSchoolATX, they are REQUIRED to spend 2 hours every day studying. Not coding. Studying and reading papers on cognitive load theory, motivation research, and translating learning science into applications. Two hours. Every single day. Engineers like @yiran__c write about the neuroscience of handwriting. @arpangup shares the Harada Method. @LamarDealMaker explores AI for skill development. This isn't optional. It's the job. Your success metrics will lie to you. High DAUs don't mean kids are learning. Viral engagement doesn't mean mastery. The metrics that drive consumer tech success actively undermine educational outcomes. The money will tempt you to build the wrong thing. EdTech market: $400B by 2030. That capital creates pressure to optimize for pitch decks instead of classrooms. Byju's hit $22B before collapsing. An MBA analyzes constraints. A builder changes reality. What we require: ➡️ Mission Alignment ➡️ Agency ➡️ Strong Engineering Skills If you're chasing market opportunity or building for your resume, don't apply. But if you're a builder who sees broken systems and feels an overwhelming need to fix them? If you believe high standards create happy kids? If you want to change education for a billion children? Before applying, read the link in the reply. And if you're still interested after understanding what it really takes, let's talk about joining us in building the future of EdTech.

I think @SpaceX's real value probably comes from @Starlink, not from selling rocket launches. Future Moon and Mars settlements will need fleets of robots, vehicles, sensors, and autonomous machines working together. They’ll all need a communication network. Starlink🚀🚀🚀

A few of the 20 games on blumsons-game-vault.replit.a… Built on @Replit using Fable, running multiple parallel agents to build all your recognisable, favourite games. Intentionally simple, hyper casual games. Collab with @Andrew_Blumson. No ads. No purchases. Works as a PWA.

My daughter came home with a red, irritated patch on her cheek. I uploaded a photo of her skin and a shelf at Olive Young. GPT analyzed both images and recommended a specific mask pack. My daughter used it that night. By the next morning, the redness had fully improved. Diagnosis → recommendation → purchase → outcome That’s where AI starts creating value in the physical world.

My paused project #1. I tried to invite AI into real conversations. When users are talking, the AI reads the live context and autonomously surfaced what people actually needed at the exact moment. What I learned: 1. AI understands context well, even in fast, multi person conversations in real time. 2. But delivering the right content at the right timing needs more calibration and engineering than I expected. 3. Some startups are already building this at the SaaS layer. What happens when AI starts participating in the conversation itself?

Cornell engineers have developed a robotic collective that behaves less like a machine and more like a material that flows, reshapes, and adapts to its environment without centralized control. The system, called the Cross-Link Collective, consists of dozens of small robots that have limited mobility individually, but together exhibit coordinated and sustained motion. The research, published May 20 in Science Robotics, demonstrates a robotic system that resembles soft matter, continuously deforming and reorganizing as it moves, driven by what researchers call mechanical intelligence. @CornellEng @CornellRsrch Read more: news.cornell.edu/stories/202…

Built this 3D block design tool on Replit. I let AI build its own kingdom. How does it look like?🧐

I've been making a book on Replit just for my son who loves books, but avoids reading sentences. After each story set, I asked the Replit agent to generate the next chapter, slowly emphasizing more science and informational content. As we repeated this process, something unexpected happened. The agent started drawing my son older in the illustrations. It felt like the book was quietly growing with him.

Have your agent read the whole app again just to fix one tiny bug? That’s when you realize vibe coding is also context management. Claude taught me about context.md, and it changed how I work. As projects grow, the agent must reread increasingly large amounts of code on every request, consuming tokens just to rebuild its understanding of the app structure before it can even start solving the problem. That’s why small bugs sometimes feel expensive. In vibe coding, keeping the context MD up to date and adding a brief summary of failed attempts can save both tokens and unnecessary rethinking.

What does a BLACK HOLE actually sound like? NASA turned this supermassive monster in galaxy M87 into pure audio. It’s real data. Turn the volume up. Done? Now here is how you are able to hear this:

As electronic systems become denser and more power-hungry, engineers are rethinking how power architectures are designed. This article explores how integrated power modules and validated discrete components can simplify development while improving efficiency, thermal performance, and reliability. From industrial automation and EVs to IoT and embedded systems, modern designs require scalable power solutions that reduce PCB complexity and accelerate deployment. The article also examines the tradeoffs between discrete and integrated approaches, and why pre-validated power architectures are becoming increasingly important for faster product development and long-term system stability in high-performance electronics.

Added an aurora layer to my @Replit app. Now the light itself becomes part of the design system (color, rhythm, mood, intensity), all reacting to the objects I build. It feels more like composing emotional physics. Now I’m searching for one powerful engagement loop. Something that makes people instantly want to touch, remix, and share their own atmosphere. Ideas are very welcome.

So much beauty that I have seen being made - I love that - I wouldn't even know where to start for prompts to get that going! 😁 have you got one i can play with - I just saw this build with the most life like flowers it was incredible.

Thanks to my @Replit agent 🙌 My agent4 didn’t just build the app, it tested it again and again before handing it to me.
