Next.js App Router: enforcing non-bypassable server-side route gating with middleware vs server components

by

Summary In a Next.js v16+ App Router application, enforcing non-bypassable server-side route gating for compliance-critical flows (like identity verification) requires understanding the distinction between middleware execution and Server Component rendering. The central finding is that middleware is the preferred enforcement layer for route-level gating, providing a pre-render security boundary that decouples authentication/authorization logic from UI … Read more

How to draw multiple objects of the same shape in SFML using VertexArray?

by

Summary The problem at hand is drawing multiple objects of the same shape in SFML using VertexArray. The provided code snippet successfully draws a single rectangle, but the goal is to replicate this shape multiple times on the screen for collision testing purposes. Key takeaways include understanding how to utilize VertexArray efficiently for multiple shapes … Read more

how should data for ai looks like for RAG Finetuning and LLM

by

Summary The question conflates two distinct AI paradigms: RAG (Retrieval-Augmented Generation) and LLM Fine-tuning. A common production failure is treating data preparation for these two as interchangeable, leading to ineffective models and wasted compute. This postmortem outlines the correct data structures for both approaches and identifies where to source them. The core distinction is that … Read more

How to tell Bson to parse an integer values into BaseInt64

by

Summary Key Issue: The default BSON decoder in the MongoDB Java driver always interprets numeric JSON literals as BsonInt32, even when the values exceed the 32-bit integer range. This causes silent data truncation or precision loss when parsing JSON strings directly into BsonDocument objects without explicit type specification. Root Cause The root cause lies in … Read more

PL/SQL elegant Solution for HTML-User Input

by

Summary The issue presented involves maintaining state and passing a large number of parameters in an Oracle PL/SQL Web Toolkit (OWA) application. The developer currently relies on explicitly passing T_ARR collections and individual variables via hidden form fields, leading to “parameter bloat” and brittle code. While the developer asked about owa_utils context variables, the core … Read more

Power BI Split by delimiter

by

Summary The issue at hand involves Power BI data not updating properly when refreshed in the Power BI Service, despite working correctly in Power BI Desktop. This discrepancy occurs after splitting data into rows using a delimiter. The key takeaway is that refreshing data in the Power BI Service does not always update the data … Read more

Next.js 16 cache components

by

Summary A developer attempted to implement a cached utility function to generate the current year within a Next.js 16 server component using the experimental use cache directive. The goal was to cache the value of new Date().getFullYear() to satisfy framework constraints preventing non-deterministic time access inside prerendered components. The approach, wrapping the time call in … Read more

Jetty 12 Startup Time Optimization Using QuickStart module

by

Summary The Jetty 12 startup time optimization is a critical issue, especially when dealing with a large number of deployments. In this case, the Jetty 12.1.4 version is being used with e11 deployment, and around 36 files (18 wars with mapping 18 context XML configuration files) are deployed in the Jetty server. The startup time … Read more

Lack of semantic abstraction and unreliable tool invocation

by

Summary The core issue is a breakdown in the semantic abstraction layer between natural language inputs and database execution. In the current setup, the Model Context Protocol (MCP) integration fails to provide a true business-facing abstraction, forcing users to expose physical database schemas. Additionally, the LLM’s tool invocation is non-deterministic; it occasionally bypasses the MCP … Read more
