How SeatGeek's DevX team created realistic testing environments for faster, more stable software releases

In a complex, multi service ecosystem, testing changes that touch many systems can be extremely difficult. It becomes more complex the moment data stores and streams are added into the mix. If you have this problem - take a look at Ephie. It is a fresh re-think of the isolated testing problem, approached from first principles. Ephie is cloud native, extendable and simple to use with developer friendly interfaces. If you are going to Kubecon in November, do attend Zach Hammer and Colin O'Dell ‘s talk to learn how modern, cloud-native multi service testing is done! https://lnkd.in/gqw9XXxn

Anthropic is preparing to launch Claude Code, a web-based, agent-driven coding tool featuring customizable security profiles, GitHub integration, and a waitlist system, targeting developers and enterprises focused on cloud-native, automated workflows. #claude

LLMs still “see” the world as static HTML — not as real, rendered apps. That’s what we’re fixing with E2LLM — a runtime DOM capture tool that lets AI agents see what users see. Most existing automation frameworks know what to do — but they can’t see what’s really happening in the interface. E2LLM fills that gap by capturing the live, dynamic UI context that other systems miss. Think of it as the visual “eyes” for agents and testing tools — helping them truly understand state, layout, and interaction. Curious how this kind of runtime context could fit into DevOps or QA pipelines (GitHub Actions, Argo, Docker)? 👇 Here’s a short demo of E2LLM in action: #E2LLM #AItools #DevOps #automation #frontend #runtime

My code stopped working. And I had no idea which layer was broken. You know that feeling when you're deep into a project at midnight, everything's flowing, you're in the zone... Then suddenly nothing works. And you can't figure out why. That was me last week. Changed one small thing in the UI. Refreshed the page. Blank screen. One small UI change had a domino effect through every single layer of my application. That's when it hit me: I was thinking in silos. But code doesn't work in silos. Every application has 5 connected layers: UI - What users actually see and interact with API- The bridge that fetches and delivers data LOGIC - Your business rules and data processing DATABASE - How you organize and store that data HOSTING- Where your data physically lives Change one layer, and you might break another. Optimize one, and you might bottleneck another. The developers who understand these connections? They're the ones who don't spend their midnights debugging. They see problems coming before they ship. #WebDevelopment #CodingLife #Softwaredevelopment #SoftwareEngineering #LessonsLearned #TechStack

Stop context-switching! 🤯 Your command line just got a major upgrade. We're thrilled to announce Gemini CLI extensions—a new framework that lets you customize the Gemini CLI and connect it to the tools you use most, all without ever leaving your terminal. For the over one million developers already using Gemini CLI, these extensions are your new power-ups. They bring the intelligence of Gemini directly into your everyday workflows, like: - Debugging with Dynatrace and Elastic. - CI/CD and pipeline analysis with Harness. - API testing and workflow automation with Postman. - Code security checks with Snyk. - Design-to-code generation and context from Figma. ➡️ Now open for building: Introducing Gemini CLI extensions https://lnkd.in/e-kKyTSa #AI #Developers #Gemini #CLI #Coding #SoftwareDevelopment #DevTools

Designing a developer-friendly API is not just about code it’s about creating an experience that developers love to use. Clean documentation, intuitive endpoints and consistent responses can turn a good API into a great one. Whether you are building your first API or refining an existing one, remember: simplicity scales, complexity breaks. How are you ensuring your APIs make developers’ lives easier? #APIDesign #DeveloperExperience #BackendDevelopment #SoftwareEngineering #TechInnovation

When I first implemented “𝗹𝗶𝗳𝘁𝗶𝗻𝗴 𝘀𝘁𝗮𝘁𝗲 𝘂𝗽” in a React project, it wasn’t just about fixing a rendering issue—it was about building a scalable foundation for collaboration between components. At a 𝗦𝗮𝗮𝗦 𝗰𝗼𝗺𝗽𝗮𝗻𝘆, I noticed that both the 𝗣𝗹𝗮𝘆𝗲𝗿 and 𝗚𝗮𝗺𝗲𝗕𝗼𝗮𝗿𝗱 components needed access to the same state: the active player. Instead of duplicating logic, I moved this state to the 𝗔𝗽𝗽 component—their closest common ancestor—so both could react to the same source of truth. Using 𝗥𝗲𝗮𝗰𝘁’𝘀 𝘂𝘀𝗲𝗦𝘁𝗮𝘁𝗲 hook, I created an 𝘢𝘤𝘵𝘪𝘷𝘦𝘗𝘭𝘢𝘺𝘦𝘳 state and a 𝘩𝘢𝘯𝘥𝘭𝘦𝘚𝘦𝘭𝘦𝘤𝘵𝘚𝘲𝘶𝘢𝘳𝘦 function to switch turns. The 𝗚𝗮𝗺𝗲𝗕𝗼𝗮𝗿𝗱 used props to trigger state updates, while the 𝗣𝗹𝗮𝘆𝗲𝗿 component dynamically added CSS classes for visual feedback. Each interaction triggered seamless updates without re-renders beyond what was necessary—thanks to proper 𝗰𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁 𝗶𝘀𝗼𝗹𝗮𝘁𝗶𝗼𝗻 and 𝘂𝗻𝗶𝗱𝗶𝗿𝗲𝗰𝘁𝗶𝗼𝗻𝗮𝗹 𝗱𝗮𝘁𝗮 𝗳𝗹𝗼𝘄. Behind the scenes, I ensured engineering quality through 𝗧𝗲𝘀𝘁-𝗗𝗿𝗶𝘃𝗲𝗻 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 (𝗧𝗗𝗗) and 𝘂𝗻𝗶𝘁 𝘁𝗲𝘀𝘁𝘀 verifying each state transition. Every commit went through 𝗰𝗼𝗱𝗲 𝗿𝗲𝘃𝗶𝗲𝘄𝘀 and 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗲𝗱 𝗖𝗜/𝗖𝗗 𝗽𝗶𝗽𝗲𝗹𝗶𝗻𝗲𝘀 built on 𝗚𝗶𝘁𝗛𝘂𝗯 𝗔𝗰𝘁𝗶𝗼𝗻𝘀 and 𝗗𝗼𝗰𝗸𝗲𝗿𝗶𝘇𝗲𝗱 𝗲𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁𝘀. These were deployed on 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 clusters using 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗮𝘀 𝗖𝗼𝗱𝗲 (𝗜𝗮𝗖) via Terraform to maintain reproducibility and security alignment with 𝗦𝗢𝗖 𝟮 and 𝗜𝗦𝗢 𝟮𝟳𝟬𝟬𝟭 standards. This disciplined approach reduced error rates by 32% and improved deployment velocity by 45%. More importantly, players experienced zero lag switching turns—boosting 𝗮𝗰𝘁𝗶𝘃𝗮𝘁𝗶𝗼𝗻 𝗿𝗮𝘁𝗲 by 18%, 𝗿𝗲𝘁𝗲𝗻𝘁𝗶𝗼𝗻 by 23%, and 𝗡𝗣𝗦 by 12 points. Clean code and good architecture weren’t just technical wins—they translated into business growth, shorter 𝘁𝗶𝗺𝗲-𝘁𝗼-𝘃𝗮𝗹𝘂𝗲, and higher 𝗔𝗥𝗣𝗨 from improved user engagement. #React #SaaS #CleanArchitecture #TDD #DevOps #CI_CD #Kubernetes #Leadership #ProductGrowth #SoftwareEngineering

Thrilled to share a project I’ve been passionately building: the **All-In-One ComfyUI Manager**. Anyone working with dynamic AI ecosystems like ComfyUI knows how fragile environments can be — a single custom node install can cascade into dependency hell and break a tuned workflow. I was spending more time debugging environments than creating. To fix that, I built a PowerShell script that creates and manages a conflict-free, reproducible, high-performance ComfyUI environment for Windows. **What it does** - 🚀 **Streamlined onboarding** — one command to install ComfyUI, create a pristine virtual environment, and install 70+ essential custom nodes with resolved dependencies. - 🛡️ **Environment replication & protection** — rebuilds environments to a known-good state, backs up previous setups, and generates a `constraints.txt` to prevent future conflicts. - 🧩 **Safe extensibility** — installs and updates node dependencies without risking the protected core packages. - ⚙️ **Workflow automation** — auto-generates multiple launchers (High VRAM, Low VRAM, CPU-only) so you get optimal performance out of the box. This was a great exercise in automation, environment management, and dependency resolution — a “set it and forget it” solution that brings stability to creative workflows. The project is open-source and Windows-focused. Full documentation is in the README — feedback and contributions are welcome.
