Let’s get one thing straight: creativity isn’t some mystical power you’re born with. It’s not just for artists, musicians, or “creative types.” It’s for anyone who wants to think differently, solve problems, or make something new. And despite what you might’ve heard, creativity doesn’t start with talent or inspiration. It starts with mindset. In myContinue reading “The Three Traits of Creative Thinking: Curiosity, Ignorance, Resiliency”

Troubleshoot Java Applications: Master Thread Dumps with ThreadLogic
Diagnosing performance issues in Java applications often starts with analyzing thread dumps — a notoriously complex and tedious task. ThreadLogic, an open-source tool originally developed by Oracle (formerly part of BEA’s diagnostic toolkit for WebLogic), simplifies this process by offering visual insights and automated detection of threading problems. This guide walks through using ThreadLogic toContinue reading “Troubleshoot Java Applications: Master Thread Dumps with ThreadLogic”
Why Is WebSocketMonitoringModule Throwing 500 Errors When WebSockets Are Disabled?
If you’ve ever poked around the diagnostics blade in Azure App Service and spotted a bunch of 500 errors blamed on something called WebSocketMonitoringModule, you’re probably thinking: “Wait… what? I didn’t even turn on WebSockets!” And you’d be right. You scroll back through your app settings, double-check the config (yep, WebSockets: Off), and yet thereContinue reading “Why Is WebSocketMonitoringModule Throwing 500 Errors When WebSockets Are Disabled?”

Performance Considerations Between Lua Scripts and Basic Commands in Redis for Cloud Applications
Choosing Between Lua Scripts and Basic Commands in Redis for Cloud Applications When using Redis—whether on Azure or elsewhere—the decision between Lua scripts and basic commands (such as StringSet) can significantly impact both performance and maintainability. Redis is widely used in cloud environments for caching, session management, and real-time analytics due to its high-speed in-memoryContinue reading “Performance Considerations Between Lua Scripts and Basic Commands in Redis for Cloud Applications”
Understanding ARR Affinity for Stateful Applications
=============================================== Overview:Application Request Routing (ARR) Affinity is often discouraged in cloud-native architectures due to concerns about scalability, resiliency, and performance. However, there are specific scenarios where enabling ARR Affinity in Azure Web Apps can be beneficial and even necessary to maintain application functionality and improve the user experience. This article outlines the advantages of ARRContinue reading “Understanding ARR Affinity for Stateful Applications”
Mastering Technical Troubleshooting: A Step-by-Step Guide
Troubleshooting technical issues is an art as much as it is a science. Whether you’re diagnosing software failures, network disruptions, or performance bottlenecks, the ability to ask the right questions and gather meaningful data is critical to resolving problems efficiently. In this blog, I’ll share a structured approach to troubleshooting, including nine key questions thatContinue reading “Mastering Technical Troubleshooting: A Step-by-Step Guide”
Crisis Management in Tech Support: An ER Doctor’s Approach
Thinking Like an ER Doctor: A Game-Changer for Technical Support Professionals We’ve all seen those dramatic medical dramas where ER doctors and nurses save lives in a blur of activity—barking orders, making snap decisions, and heroically stabilizing patients just before the next commercial break. Somewhere in the middle of one of those breaks—probably while aContinue reading “Crisis Management in Tech Support: An ER Doctor’s Approach”
Effective Alternatives to Kernel Dumps in Azure App Services
When troubleshooting complex application issues, kernel dumps are invaluable for diagnosing low-level problems such as driver conflicts, kernel-mode memory issues, or other operating system-level behaviors. However, in Azure App Services, capturing full kernel dumps is not an option due to the platform’s managed and sandboxed nature. This article explains the reasons behind this limitation andContinue reading “Effective Alternatives to Kernel Dumps in Azure App Services”
Impact of Child Process Crashes on Web App Stability
In Azure Web Apps, child processes are essential for managing specialized workloads that the main application delegates to improve performance and responsiveness. These tasks often include image optimization, PDF generation, or external API requests. A child process is a lightweight, auxiliary executable spawned by the parent worker process (w3wp.exe). This modular architecture boosts scalability butContinue reading “Impact of Child Process Crashes on Web App Stability”
