Indexed Views in SQL Server: A Production DBA's Complete Guide
After fifteen years of wrestling with SQL Server performance challenges in production environments, I can confidently say that indexed views remain one of the most underutilized yet powerful features for optimizing query performance. Introduced in SQL Server 2000 and significantly enhanced in subsequent versions, indexed views (also known as materialized views) allow you to physically store the result set of a view on...

Hey folks, Back when I was learning in the pre-LLM era, I read a lot of articles (and books like Hacker's Delight) filled with dozens of clever bitwise tricks. While they were fun and engaging (not really), I quickly realized that in everyday "JSON-moving" jobs, most of them donβt really come up, especially when readability and maintainability matter more than squeezing out CPU cycles. But, some of those tricks...

In the age of machine learning and AI-driven decision-making, model accuracy is often touted as the holy grail. Teams boast of hitting 95%+ F1 scores or outshining baselines by double digits. However, high accuracy in development environments means very little if the model is fed garbage in production.

LLMs may speak in words, but under the hood they think in tokens: compact numeric IDs representing character sequences. If you grasp why tokens exist, how they are formed, and where the real-world costs arise, you can trim your invoices, slash latency, and squeeze higher throughput from any model, whether you rent a commercial endpoint or serve one in-house. Why LLMs Donβt Generate Text One Character at a Time Imagine...
