Decentralized Systems & Applications

**The Test Tribe 2nd Washington Meetup – Designing a Modern QA Organization: Structure, Skills, and Shared Ownership** AI is accelerating software delivery at an unprecedented pace-but speed without structure introduces serious risk. In today’s landscape, the traditional “testing bottleneck” isn’t just a delay-it’s a business liability. This session explores how Quality Engineering must evolve from a siloed function into a strategic, distributed capability-one that balances rapid AI adoption with strong human oversight. Moving beyond basic automation, this talk introduces the concept of Distributed Quality Governance, where quality becomes a shared responsibility across engineering, product, and leadership. Expect a practical, leadership-focused discussion that cuts through AI hype and addresses the real challenges of testing complex, AI-assisted systems-while ensuring accountability, trust, and long-term resilience. **Event Details** * **Date: 21st January 2026 (Wednesday)** * **Time: 6:00 PM – 8:00 PM EDT** * **Location: 1501 Langston Blvd. Arlington, Virginia** **Session: Designing a Modern QA Organization: Structure, Skills, and Shared Ownership** **Speaker: Alekhya Guduri** **About the Session** In an era where AI-generated code is accelerating delivery, quality can no longer be treated as a final checkpoint. Instead, it must be embedded, intentional, and governed. In this session, Alekhya Guduri presents a blueprint for building a modern QA organization that operates as a strategic business function. You’ll learn how to shift from centralized testing teams to shared ownership models, while introducing guardrails that ensure responsible AI use across the delivery pipeline. From defining a Materiality Matrix to identify where AI risks are too high to ignore, to implementing Human-in-the-Loop frameworks, this talk provides actionable guidance for leaders navigating AI-driven engineering environments. **Key Takeaways** * The Materiality Matrix: How to objectively prioritize AI risks based on business impact and technical complexity * Distributed Governance: Transitioning from centralized QA to shared ownership in AI-driven CI/CD pipelines * Responsible AI Guardrails: Practical Human-in-the-Loop frameworks to prevent bias, hallucinations, and silent failures **About the Speaker** Alekhya Guduri is a seasoned technology leader whose career sits at the intersection of engineering execution, operational excellence, and innovation. As Director of Engineering at Indeed, she focuses on building high-performing organizations that treat quality as a strategic advantage, not a last-mile activity. With deep experience scaling complex systems and leading cross-functional teams, Alekhya works at the forefront of shaping how AI and human judgment coexist within modern software delivery. She is a strong advocate for distributed governance, responsible AI practices, and the evolution of Quality Engineering into a trusted business partnership. **Why You Should Attend** * Learn how to design QA organizations for AI-driven delivery * Understand how to balance speed with responsibility in modern pipelines * Gain leadership frameworks for shared ownership of quality * Move beyond AI hype to practical, defensible testing strategies * Connect with Washington-area QA, engineering, and tech leaders **About The Test Tribe** **The Test Tribe** is the world’s largest software testing community, empowering testers globally since 2018.

Title: Quantum Enhanced Digital Therapeutics: Human Computer Interaction (HCI) and Health Informatics for Mental Health Date: Jan 24 2026 13:00 - 15:00 EST Summary: This talk offers an accessible overview of how quantum computing ideas may inform the next generation of digital tools for mental health. Ishan will sketch potential roles for pattern discovery, adaptive interfaces guided by human-computer interaction, and approaches to protect patient privacy, using examples drawn from public literature. The focus is on what is feasible now, what remains experimental, and how careful evaluation can guide responsible progress in health informatics. The session closes with open questions and a practical framing to help the community explore this space. An overview of where quantum computing could add value to digital mental health tools today, what is still experimental, and how human-computer interaction and health informatics can guide responsible evaluation. Speaker: Ishan Shivansh Bangroo is a graduate researcher at Penn State University in the College of Information Sciences and Technology. His work sits at the intersection of health informatics and human-computer interaction, with a growing interest in quantum-inspired methods. He studies adaptive clinical interfaces and trustworthy analytics for mental health support, aiming to make digital tools clearer, safer, and easier to use.

This month, we're discussing API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. *Note the slightly different time than usual.* We're still at the West End Library. **Agenda:** \- 1:45 \- 2:45pm: Library discussion \- 2:45pm \- whenever: Keep chatting over lunch nearby **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

**NEW LOCATION - THE DAILY GROWLER -** **2812 Fishinger Rd, Upper Arlington, OH 43221** Over the years, we’ve heard two requests constantly: 1.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group × DevOps Columbus** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS, Columbus HashiCorp User Group, and DevOps Columbus meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/azure-cbus-2026/
