By default, all pods in a Kubernetes cluster can talk to each other. This is a security risk. If a frontend pod is compromised, the attacker can scan your database pod. Network Policies act as an internal firewall. Deny All Ingress Start by blocking everything. Allow Frontend to Backend Key Takeaways You must enable a […]

C# 10: File-Scoped Namespaces
Vertical whitespace is valuable. The “block-scoped” namespace syntax indents every single class in your project, wasting 4 spaces of indentation. C# 10 introduces File-Scoped namespaces to reclaim that space. Comparison Key Takeaways Use `dotnet format` or IDE cleanup to convert your entire solution automatically. You cannot mix file-scoped and block-scoped namespaces in the same file.

.NET MAUI (Multi-platform App UI) is the evolution of Xamarin.Forms. It introduces a single-project structure to target Android, iOS, macOS, and Windows. Single Project Structure No more `App.Android`, `App.iOS` projects. Resources (Images, Fonts) are shared automatically. The Handler Architecture MAUI ditches Renderers (slow, tightly coupled) for **Handlers**, which map virtual controls to native controls more […]
Read more →Azure Web PubSub: Real-time WebSockets
SignalR is great, but sometimes you want raw WebSockets or support for other languages (Python, Java clients). **Azure Web PubSub** is a managed WebSocket service that supports native WebSocket clients and the PubSub subprotocol. Architecture The service handles the massive concurrent connections. Your server only handles events (Connect, Message) via Webhooks. Key Takeaways Supports standard […]
Read more →Azure SQL Database Ledger: Blockchain power in SQL
Ledger functionality adds tamper-evidence to Azure SQL. It cryptographically links blocks of transactions together (like a blockchain), creating an immutable history. If a DBA tries to modify a row in the history table directly, the cryptographic verification fails. Creating a Ledger Table Verification You can run a stored procedure to verify the integrity of the […]
Read more →Container Security: Running as Non-Root
By default, Docker containers run as `root`. If an attacker compromises the app, they have root access to the container (and potentially the host). Running as a non-root user is a critical security best practice, mandated by policies like Azure Policy for Kubernetes. The Dockerfile Fix Key Takeaways You cannot bind to ports < 1024 […]
