3D web development gets a lot easier when you can see the full workflow. In this course, you’ll build a cozy cafe portfolio with Blender and Three.js from scratch. You'll go from modeling and texture painting to interaction and performance optimization. freecodecamp.org/news/3d-web-de…

When data scientists start a project, they always ask: "How does the output change when the input changes?" And while the equation y = ax+b answers it in the simplest way, neural networks try to answer it in a more flexible way. In this tutorial, Samyutka explains how neural networks work using y = ax +b. freecodecamp.org/news/neural-ne…

Carbon fibre is redefining UAV performance. Lighter airframes → longer flight time Stronger structures → mission-ready durability Engineered for ISR. Built for real operations. Briech UAS. #BriechUAS #UAV #DroneTech #ISR #DefenceTech

Not all data pipelines need to run in real time. Some are better as scheduled batch jobs, others need streaming from the start. In this tutorial, @balawc27 teaches you the differences between batch and streaming pipelines in Python, and when to use each. freecodecamp.org/news/efficient…

Classical computers crunch numbers. 🔢 Quantum computers mimic the universe. ⚛️ Celebrate World Quantum Day with us by learning how the shift to qubits is unlocking the future of medicine, chemistry, and AI: ibm.co/6013EJWWF

Learning DevOps can be challenging, and it's difficult to know where to start. Sometimes, some hands-on experience does just the trick. Here, @nitheeshp shows you how to build a GitOps pipeline for a production grade app. freecodecamp.org/news/from-comm…

Spinning, jumping, and incredibly smooth! Chinese university students have built their own wheeled-legged robot for RoboMaster—a global robotics competition founded by DJI (大疆), the world’s largest consumer drone maker based in Shenzhen. The robot shows impressive agility, balance, and control. Would you ride one? Video from ZeRo @RoboMasterDJI @CNYouthDaily @CyberRobooo @QinduoXu

It's World Quantum Day, and we're celebrating with a story about the power of open education. Omar Alshehri used resources from @MITOCW to go from industrial engineering to quantum physics — logging 300+ hours of self-study that helped him earn his PhD. Read his story on MIT Learn: bit.ly/4stTB0p

4 hub motors, aluminum frame, 3D-printed brackets, and a rear suspension — full 4WD AGV chassis, open-source with STL files. Our M0601 Direct-Drive Hub Motors with integrated FOC servo, 7 steps from parts to rolling platform. No guesswork. Build guide + files 👇 instructables.com/4WD-Mobile-Pla… Anyone else gone direct-drive hub motors over traditional motor+wheel setups? Curious how it's worked out for you. #Makers #Robotics

n8n is a powerful open source workflow automation tool that lets you connect your apps, APIs, and AI models. And this course teaches you how to use it to build and orchestrate intelligent agents. You'll set up a vector database, build a customer support RAG agent, and learn about various hosting options, too. freecodecamp.org/news/learn-n8n…

When you're learning about AI & machine learning it's helpful to build things from scratch. And that's what you'll do in this course. You'll learn Neural Networks by manually adjusting the network parameters while building a self-driving car playground. freecodecamp.org/news/understan…

Indian factory workers are wearing head-mounted cameras to record hand movements for training AI.

Founder’s Friday with Michelle Chamulabye, CEO Charge24. We got into what it actually looks like to build when things aren’t clear yet. Making decisions without perfect information, adjusting fast, and staying consistent even when the path keeps shifting. A few things that stood out: * Execution > waiting to feel “ready” * Clarity comes from doing, not overthinking * You don’t need the full plan to take the next step * Resilience is built in the process, not before it From idea to execution isn’t a straight line and that’s the point. Join us every Friday for Founders Friday session. @base @BasedEastAfrica

Many devs use AI tools when building applications these days. And while these tools are powerful, the code they produce typically needs some human review and tweaking. In this tutorial, Wisamul explains how to build production-grade AI applications & covers best practices along the way. freecodecamp.org/news/how-to-bu…
