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

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

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

Power BI Split by delimiter

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

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

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

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

Performance of square root calculation – expectation versus reality

Summary A user-level benchmark suggests that math.sqrt(x) is approximately 20% faster than x**0.5 for calculating square roots in Python. While both operations are mathematically equivalent for positive numbers, the performance difference stems from how the Python interpreter and underlying C libraries handle these operations. math.sqrt maps directly to a low-level C library call optimized specifically … Read more

Some users cannot type anything

Summary A critical input failure occurs where some users cannot type into a JTextArea within a JAR deployment, while the same code works in development environments. The root cause is a blocking EDT (Event Dispatch Thread) behavior triggered by the heavy KeyListener logic, causing the UI thread to freeze intermittently or under specific system conditions … Read more

Autodesk Forge Viewer: setGhosting() + isolate() not making elements transparent – topography transparency issue

Summary During a feature implementation for a “Transparent Topography” button in Autodesk Forge Viewer v7.x, the expected ghosting behavior failed. The goal was to make FBX topography elements transparent while keeping Revit (RVT) and Navisworks (NWD/NWC) elements opaque. The implementation relied on setGhosting(true) combined with isolate() on non-FBX elements. The result was inconsistent: sometimes FBX … Read more
