Dev shares insights from his experiences in DevRel, the challenges of the industry, and the significance of event sourcing in modern applications.We then discuss the intricacies of event sourcing, exploring its implications for software architecture, performance, and testing. The discussion highlights the importance of projections, caching, and the separation of command and query responsibilities (CQRS) in building efficient applications. Real-world applications, such as Git and Redux, are examined as examples of event sourcing in practice.Finally, we explore Solid.js and its comparison with React, focusing on fine-grained reactivity, the challenges of adopting new frameworks, and the evolution of web development practices. They explore the unique features of Solid.js, including its compiler and async signals, while discussing the broader implications for developers transitioning between frameworks. The conversation also touches on the importance of full stack development and the mindset required to excel in the field.Chapters00:00:00 Dev Agrawal00:04:16 Becoming Notable in Tech00:14:24 Intentional Networking and Building a Presence00:24:27 The Role of Content Creation00:34:29 DevRel Insights and Career Transitions00:44:05 Understanding Event Sourcing00:43:37 Caching and Performance in Event Sourcing00:48:42 Real-World Applications of Event Sourcing00:51:31 Command Query Responsibility Segregation (CQRS) Explained00:54:24 Event Sourcing in UI State Management00:57:25 Overcoming Resistance to Event Sourcing01:00:22 The Challenges of Transitioning to Event Sourcing01:04:34 Storing Events and Schema Management01:07:16 Testing with Event Sourcing01:08:51 Introduction to Solid.js and Its Advantages01:13:12 Understanding Fine-Grained Reactivity01:15:06 Challenges in Replacing React01:16:30 The Unique Model of Solid.js01:18:22 The Catch-22 of Learning React01:19:52 Comparing Fine-Grained Reactivity in Solid and React01:23:50 The Role of Solid's Compiler01:25:57 Exploring Solid.js 2.0 and Async Signals01:28:55 Server-Side Rendering and Async Signals01:35:08 Partial Pre-Rendering and Edge Workers01:37:41 Becoming a Full Stack Developer

The conversation highlights the distinction between the "human web" and the "agent web," emphasizing the need for new approaches to ensure agents can effectively understand context and execute tasks.Key topics include contextual alignment protocols like MCP (Machine Context Protocol), and standards such as `llms.txt` and `agents.json`, alongside efforts like Arrazo, which aim to provide structured information and enable complex workflows for agents. A significant portion of the discussion focuses on the challenges of authentication for agents, moving beyond human-in-the-loop processes and complex systems like OAuth2 towards more agent-friendly, secure, and auditable solutions, possibly involving dedicated agent user identities.The dialogue also covers practical considerations like providing data to LLMs efficiently, the importance of API accessibility for agents, and the need for businesses to adapt to this new paradigm of interaction. Finally, the conversation underscores that AX is a rapidly evolving area, transitioning from theoretical concepts to practical applications, with a strong call for community collaboration to develop best practices and robust solutions for the future of agent-driven web interactions.Chapters00:00 Intro03:35 Exploring Agent Experience (AX) and Its Importance06:23 Understanding the Role of Model Context Protocol (MCP)09:22 The Principles of Great Agent Experience12:24 Agent Accessibility and Its Challenges15:34 Contextual Alignment: Enhancing Agent Interaction18:31 Human-Centric Design in Agent Experience21:23 The Future of AI and Agent Experiences24:25 Improving Human Accessibility Through Agentic Experiences27:29 Primitives of Agent Accessibility30:22 Avoiding Human in the Loop Patterns33:19 Authentication in an Agentic World38:34 Navigating API Token Strategies43:30 Contextual Alignment: The Next Frontier55:50 Understanding Agents vs. Bots01:00:19 Optimizing Contextual Alignment for Agents01:14:11 Understanding Website Infrastructure and Cost Implications01:14:37 The Role of LLMs in Web Navigation01:17:54 Quantifying ROI in Web Technologies01:19:43 Introduction to Arazo and Workflow Management01:24:26 Measuring Human vs. Agent Interaction01:30:28 The Emergence of Agent Experience (AX)01:38:09 Five Principles of Agent Experience (AX)

He emphasizes that management is a "side step" not a "step up" from an Individual Contributor (IC) role. The conversation moves into why engineers often leave jobs after two years, the importance of finding fulfilling work, and how a colleague's comment ("planted the seed") and the book "Staff Engineer's Path" helped him pursue the promotion.A significant portion covers Santhosh's personal health journey after a Type 2 diabetes diagnosis, which led him to prioritize health, drop conference speaking, and take up running. He shares his progress from struggling with 3km to completing a half marathon, emphasizing listening to his body, proper gear, rest, and not comparing himself to others. This inspired him to launch devswhorun.dev to motivate other developers.Other topics include:- The value of validation and good managers.- Dealing with toxic work environments (advice: leave).- Productivity while working from home.- His podcast "This is Tech Talks" and interest in home automation.The core message: cherish what you have and the importance of health for sustainable impact.Chapters00:00:00 Santosh Yadav00:04:31 Introduction and Guest Welcome00:05:31 Career Progression and Promotion Journey00:11:36 The Importance of Staying in One Place00:15:21 Understanding Solonis and Its Impact00:19:29 The Role of a Staff Engineer00:24:29 The Value of Validation in Career Growth00:31:31 Balancing Health and Career00:39:44 Conclusion and Future Aspirations00:40:39 Fitness Journey and Personal Records00:41:31 The Impact of Niceness on Management00:45:25 Transforming Toxicity into Calmness00:50:25 Building Connections Beyond Work00:52:55 The Importance of Compassion in the Workplace00:54:39 Work from Home vs. Office Productivity00:57:59 Exploring AI and Home Automation01:07:37 The Evolution of Angular and Personal Health Journey01:10:11 Health Transformation and Running a Half Marathon01:16:38 The Journey of Personal Growth Through Running01:20:23 Understanding the Importance of Recovery and Rest01:22:32 Choosing the Right Gear for Running01:25:12 Leveraging Technology for Training and Recovery01:33:36 Community Building Through Shared Experiences01:36:16 Transforming Personal Challenges into Community Impact
