Structured RAG for Unknown and Mixed Languages
This article shows how naïve RAG fails on multilingual activity streams and why structure is the real fix. By extracting stable metadata into a JSON schema at write time, RAG becomes predictable again. Structured RAG trades extra processing for accuracy, debuggability, and reliable retrieval across mixed and unknown languages.
RAG with PostgreSQL and C# (pros and cons)
This article was born from a real failure while applying RAG to an activity stream. Multilingual, unstructured user content broke naïve retrieval. The experience exposed how fragile RAG can be without structure, language awareness, and disciplined pipelines—lessons learned only after deploying RAG in a real system.
Accessing Legacy Data (Fox pro) with XPO Using a Custom ODBC Provider
Accessing legacy data doesn’t require rewriting old systems. This article explains how XPO and ODBC can be combined to integrate FoxPro, AS400, and DB2 databases into modern .NET architectures, enabling the use of Blazor, .NET MAUI, and even AI agents while respecting legacy dialects and type systems.
ODBC: A Standard That Was Never Truly Neutral
ODBC has been connecting applications to databases for decades. From FoxPro’s all-in-one world to modern .NET systems, this article explores what ODBC really is, why it still matters, and how it helps reduce database dependencies while improving portability and long-term maintainability in enterprise software.
Oqtane Event System — Hooking into the Framework
Learn how Oqtane’s event system works and how to hook into it using event subscribers. This guide covers user creation, login, and custom module events — with working C# examples and best practices for building reactive, event-driven modules.
Oqtane Silent Installation Guide
While working on Oqtane prototypes, I kept running into the setup wizard again and again — so I decided to automate the whole thing. This article shows how to configure a silent installation using the appsettings.json file, define default themes, containers, and templates, and save hours when spinning up new Oqtane sites for testing or deployment.
