Welcome to this week's Top 7, where the DEV editorial team handpicks their favorite posts from the previous week (Saturday-Friday). Congrats to all the authors that made it onto the list 👏 Turning the Raspberry Pi Zero into a Hacking Gadget Sebastian Apr 16 #raspberrypi #raspberryzero 45 reactions  comments @admantium shows us how to turn a Raspberry Pi Zero into a portable "bad USB" hacking device using the P4wnP1 ALOA Linux distribution. The setup includes a web-based GUI for configuring hardware behavior and a JavaScript-compatible HID scripting language for writing entry-level exploits, all framed from a beginner's perspective for educational purposes. How I started in Linux Linux gangs and Ubuntu's Zulu roots Nishant Mishra Apr 14 #linux #archlinux #ml4wos #hyprland 21 reactions  comments @nishrico0098 shares the story of how a college laptop pre-installed with Ubuntu 14.04 and a group of friends sparked a decade-long passion for Linux. From late nights in the computer lab to running Arch Linux with Hyprland on a daily driver today, the post is a nice reminder that curiosity and community can be the best way into open source. The Hidden Cost: AI's Time Complexity Trap Ender Ahmet Yurt Apr 13 #ai #ruby #programming #performance 5 reactions Add Comment @eayurt breaks down how AI-generated code can look clean and functional while hiding serious time complexity problems like O(N²) loops that work fine in testing but grind production to a halt. Drawing from real Ruby examples, the post offers a practical checklist for reviewing AI code before it ships. Build a Talking Robot with Gemini Live and Reachy Mini Low-latency WebRTC and state management Thor 雷神 Schaeff for Google AI Apr 13 #ai #robotics #gemini #opensource 48 reactions  comments @thorwebdev walks us through building a voice-powered desk robot using Gemini Live and Pollen Robotics' Reachy Mini, complete with real-time audio conversations, expressive head movements, and customizable personalities. The open-source project supports tool calling, face tracking, and a layered motion system all configurable without writing a single line of Python. I Asked My AI 'That's Sold Out, Right?' — It Had 5 in Stock and Still Said Yes Ali Afana Apr 12 #ai #webdev #javascript #programming 6 reactions  comments @alimafana shares a production bug discovered while building an AI sales platform: an e-commerce chatbot that agreed with customers nine out of ten times when they assumed an item was sold out even when it wasn't. The post details a three-part fix involving louder data formatting, reframing corrections as good news, and programmatic output validation. We've Been Thinking About AI Code Wrong. Code Isn't Flat — It's Layers. Nhường Phan Apr 12 #discuss #ai #programming #vibecoding 5 reactions  comments @nhng_phan_d04dad6eece57 challenges the way developers think about AI-assisted coding, arguing that flat code files are a lossy compression of human intent that causes constraints to silently disappear from AI context windows. The post introduces the concept of "layered code" (structured English that flows from high-level intent down to precise logic) and explores how constraints could be inherited structurally rather than remembered contextually. I vibe-coded the same app on Supabase, Convex, Vennbase, and InstantDB. The results look the same, but they're not. Alex Davies Apr 14 #ai #architecture #backend #vibecoding 28 reactions  comments @alexdavies74 ran the same fitness studio booking app build across four backends using an AI coding agent, and found that while the UIs looked identical, the differences in setup friction, token usage, and security outcomes were significant. The experiment surfaces how backend choice meaningfully shapes what an AI agent can accomplish on its own.
