🏢 🔍 🤖 BEYOND CONWAY'S LAW: USING AI TO REDESIGN HOW TEAMS AND SOFTWARE WORK TOGETHER From understanding organizational silos to changing the boundaries that create them SOFTWARE ARCHITECTURE · ORGANIZATIONAL DESIGN · ENTERPRISE AI From seeing the mirror to changing the reflection In my previous article, Your Software Architecture is a Mirror of your Organization , I explored how Conway's Law helps explain the relationship between organizational communication and software architecture. Teams develop their own responsibilities, terminology and ways of working. Over time, those boundaries can become boundaries in the software itself. Business rules become fragmented. Integrations become increasingly complex. Knowledge remains distributed across source code, database structures, support tickets and people's experience. But understanding why this happens raises another qu...

🏢 🧠 💻 YOUR SOFTWARE ARCHITECTURE IS A MIRROR OF YOUR ORGANIZATION Conway's Law: Why Organizational Silos Become Software Architecture SOFTWARE ARCHITECTURE · ORGANIZATIONAL DESIGN · ENTERPRISE AI From the Software Digital Twin to the organization behind the software In my previous article, The Software Digital Twin: The Future of Enterprise Software Management , I explored how Artificial Intelligence and knowledge graphs can connect source code, database structures, documentation, dependencies and historical changes into a continuously updated model of an enterprise software system. The goal is to move from isolated technical information to connected knowledge: understanding how an application works, what a change might affect and which knowledge needs to be preserved. But this raises a deeper ...

🚀 THE SOFTWARE DIGITAL TWIN Turning Legacy Software into Business Value Part 2 – From Technical Intelligence to Competitive Advantage What if your company's most valuable software asset is not the source code itself, but the knowledge hidden inside it? For years, companies have invested enormous resources in developing and maintaining enterprise software. Thousands of procedures. Millions of lines of code. Complex databases. Business rules accumulated over decades. Countless customizations and integrations. Yet much of this knowledge remains fragmented, undocumented, or dependent on the experience of a handful of senior developers. What happens when those developers leave? What happens when a seemingly simple modification takes days because nobody knows all the dependencies? What happens when maintaining an existing application becomes more expensive than developing new functionality? The Software Digital Twin is not just a new way to understand software...

🧠 THE SOFTWARE DIGITAL TWIN From Source Code to Executable Knowledge 🤖 Enterprise software is no longer just source code. It is a constantly evolving combination of code, data, dependencies, documentation, history, and human knowledge. The software digital twin brings these elements together in a structured, continuously updated, and queryable representation of the entire software system. Not just a code repository. Not just a chatbot. A living knowledge model of the application. 🔍 THE REAL PROBLEM: SOFTWARE COMPLEXITY A developer needs to modify a procedure. The procedure looks simple. But what happens next? Which functions call it? Which modules depend ...

EXEC sys.sp_chuck_norris; The legendary stored procedure that optimizes the DBA's soul. 💣 CPU at 18% but the server is DEAD. What do you do? When standard performance tuning fails, statistics updates won't save you. Sometimes, the bottleneck isn't in the database files—it's a deep architectural fragmentation within the team's operational patterns. Here is the ultimate story of human index optimization. 🔍 DIAGNOSIS: The 2:37 AM Nightmare One night, during an emergency shift at 2:37 AM, a junior DBA was fighting the worst incident of his career. The Symptoms: CPU at 18%, yet the server felt dead. Painfully slow logins. Random timeouts. Runnable queue completely out of control. Users screaming on Teams. Managers were already armed with the classic line: “But it was working yesterday…” The junior DBA had tried everything: ...

SQL SERVER. A deep analysis on CPU Starvation Why a server at 40% CPU can still behave like a completely saturated system 💣 Deep dive into SOS Scheduler fairness, Hekaton garbage collection, hash index scans, and why SQL Server CU5 matters far more than most DBAs think. Before we dive into today's topic, if you missed my previous post you can take a look at SQL SERVER CU5: Fixes CPU starvation issues 👉 If you found this deep-dive helpful, feel free to check out the ads—your support helps me keep creating high-quality SQL Server content for the community. 🧠 TL;DR ✔️ SQL Server uses cooperative scheduling through SOS Scheduler and workers must voluntarily yield CPU ✔️ SQL Server CU5 improves scheduler fairness during In-Memory OLTP hash index garbage collection scans 🚀 ✔️ CPU starvation can occur even when total CPU usage looks moderate 💣 ✔️ Bad hash index bucket sizing and large version chains can dramatically increase GC traversal costs ⚡ ...
