AI in Companies Isn't 50 Use Cases. It's 3 Things.
Most generative and agentic AI projects fit into three categories: agents for customers, integration layers for systems, and copilots for employees. Here is why that lens beats a list of fifty use cases.
Your Logic Apps Are a Graph, and the Azure Portal Only Shows You a List
Past a dozen workflows, an Azure Logic Apps estate stops being a list and becomes a graph connected by Service Bus queues and Event Grid topics. Here is why the portal cannot show you that graph, and what to do about it.
How Far Did That Order Get? Tracing a Correlation ID Across Cosmos DB
A customer says their order never arrived. You have a correlation id and an Azure Cosmos DB account with more containers than anyone remembers. Here is why the empty results matter more than the full ones.
GC Pauses and Latency: The Hidden Cost of High-Level Languages
Java, Python, and JavaScript offer convenience, but garbage collection introduces unpredictable latency. Explore how runtime memory management affects performance in real systems.
C Gives You Control, But at What Cost?
C avoids garbage collection and gives manual memory control, but opens the door to dangerous bugs. Explore real-world memory issues and why they matter.
Rust: Memory Safety Without Garbage Collection
Rust gives you the performance of C with memory safety enforced at compile time. Learn how ownership and borrowing eliminate entire bug classes.
Episode 6: Embeddings and Vector Databases
From keywords to meaning: how embeddings and cosine similarity let you search by proximity, why you need a vector database, and how it all comes together as a RAG.
Following a Correlation ID Through Log Analytics Without Writing KQL
A Log Analytics workspace holds the answer to where your integration flow stopped. Getting it out normally means a KQL query per table and knowing which column ties the steps together. It does not have to.
AI Commit Messages Without Handing Over Your Git History
AI git tooling tends to come in two shapes: a text box you copy out of, or an agent that runs commands and tells you afterwards. There is a third option, and it comes down to where the approval sits.
AIS Runner: A Desktop GUI for Local Azure Logic Apps Standard Development
AIS Runner is a Dioxus-based desktop app for local Azure Logic Apps Standard development — manage, run, debug, and compare workflows without leaving your dev environment.
What is `clamp` in Rust, and when should you use it?
What clamp does, why it panics on a swapped min and max, and how it differs from the saturating arithmetic it gets confused with.
What is &mut *x (reborrow) in Rust, and why does it freeze the original reference?
A reborrow duplicates the reference, not the data, and freezes the original for its duration. What &mut *x really does.
