Ruby on Rails is a full-stack web application framework built on Ruby that follows the model-view-controller architectural pattern. It features conventions over configuration, including a default directory structure, naming conventions, and configuration files. The framework emphasizes separation of concerns with the model handling data and business logic, the view handling presentation and user interaction, and the controller handling events and coordinating the model and view.
This document provides an overview of the Ruby on Rails web application framework. It discusses that Rails is a full-stack framework that follows the model-view-controller pattern and uses Ruby as its programming language. It was created by David Heinemeier Hansson in 2004 and uses conventions like separating data, presentation, and control logic into the model, view, and controller layers respectively. The document also provides high-level information on Rails' object-relational mapping, database persistence, and conventions over configuration approach.

This document provides an introduction and overview of Ruby on Rails, including what it is, its key features and benefits, and how to get started building a basic web application with Rails. Some of the key points covered include Rails' emphasis on productivity through conventions over configuration, scaffolding, and its implementation of the MVC framework and full-stack capabilities. Examples are also given of generating a controller and view to output basic text and dynamic content.
Ruby on Rails and ASP.NET MVC are both web application frameworks that implement the model-view-controller pattern. Ruby on Rails is a full-stack framework written in Ruby that emphasizes patterns like convention over configuration. It supports MVC, active record, and other patterns out of the box. ASP.NET MVC is based on ASP.NET and supports C#, JavaScript, and other languages. It allows for greater flexibility and customization than Ruby on Rails. Both support common databases and design patterns, but have different default technologies, licensing, and preferences among developers.
Ruby on Rails is an open source web application framework that allows developers to create database-backed web applications quickly using conventions over configurations. Rails emphasizes less code and faster development through features like scaffolding that can generate basic CRUD functionality and views in minutes. Popular sites like Basecamp and 43 Things were built using Ruby on Rails by small teams in short periods of time due to Rails' conventions and built-in features for caching, validation, callbacks, and Ajax support.

- Views use ERB templates to display data and helpers to DRY up common HTML patterns. Layouts wrap views in a consistent layout.
- Controllers handle HTTP requests and route them to actions that retrieve data from models and pass it to views to display. Flashes store temporary session data.
- Rake tasks help automate common
The document discusses Rails interview questions and answers. It covers common questions about what Rails is and its components like Action Pack, Action Mailer, Active Model, Active Record, Active Resource, and Active Support. Other questions addressed include RESTful architecture, advantages of Rails, scaffolding, render vs redirect_to, ORM, model associations, helpers, filters, MVC pattern, sessions vs cookies, and more.

Developing Schemas with FME and Excel - Peak of Data & AI 2025Safe Software
When working with other team members who may not know the Esri GIS platform or may not be database professionals; discussing schema development or changes can be difficult. I have been using Excel to help illustrate and discuss schema design/changes during meetings and it has proven a useful tool to help illustrate how a schema will be built. With just a few extra columns, that Excel file can be sent to FME to create new feature classes/tables. This presentation will go thru the steps needed to accomplish this task and provide some lessons learned and tips/tricks that I use to speed the process.
AI Agents in Logistics and Supply Chain Applications Benefits and ImplementationChristine Shepherd
AI agents are reshaping logistics and supply chain operations by enabling automation, predictive insights, and real-time decision-making across key functions such as demand forecasting, inventory management, procurement, transportation, and warehouse operations. Powered by technologies like machine learning, NLP, computer vision, and robotic process automation, these agents deliver significant benefits including cost reduction, improved efficiency, greater visibility, and enhanced adaptability to market changes. While practical use cases show measurable gains in areas like dynamic routing and real-time inventory tracking, successful implementation requires careful integration with existing systems, quality data, and strategic scaling. Despite challenges such as data integration and change management, AI agents offer a strong competitive edge, with widespread industry adoption expected by 2025.
Jira Administration Training – Day 1 : IntroductionRavi Teja

Neural representations have shown the potential to accelerate ray casting in a conventional ray-tracing-based rendering pipeline. We introduce a novel approach called Locally-Subdivided Neural Intersection Function (LSNIF) that replaces bottom-level BVHs used as traditional geometric representations with a neural network. Our method introduces a sparse hash grid encoding scheme incorporating geometry voxelization, a scene-agnostic training data collection, and a tailored loss function. It enables the network to output not only visibility but also hit-point information and material indices. LSNIF can be trained offline for a single object, allowing us to use LSNIF as a replacement for its corresponding BVH. With these designs, the network can handle hit-point queries from any arbitrary viewpoint, supporting all types of rays in the rendering pipeline. We demonstrate that LSNIF can render a variety of scenes, including real-world scenes designed for other path tracers, while achieving a memory footprint reduction of up to 106.2x compared to a compressed BVH.

If You Use Databricks, You Definitely Need FMESafe Software
DataBricks makes it easy to use Apache Spark. It provides a platform with the potential to analyze and process huge volumes of data. Sounds awesome. The sales brochure reads as if it is a can-do-all data integration platform. Does it replace our beloved FME platform or does it provide opportunities for FME to shine? Challenge accepted
Integration of Utility Data into 3D BIM Models Using a 3D Solids Modeling Wor...Safe Software
Jacobs has developed a 3D utility solids modelling workflow to improve the integration of utility data into 3D Building Information Modeling (BIM) environments. This workflow, a collaborative effort between the New Zealand Geospatial Team and the Australian Data Capture Team, employs FME to convert 2D utility data into detailed 3D representations, supporting enhanced spatial analysis and clash detection.
To enable the automation of this process, Jacobs has also developed a survey data standard that standardizes the capture of existing utilities. This standard ensures consistency in data collection, forming the foundation for the subsequent automated validation and modelling steps. The workflow begins with the acquisition of utility survey data, including attributes such as location, depth, diameter, and material of utility assets like pipes and manholes. This data is validated through a custom-built tool that ensures completeness and logical consistency, including checks for proper connectivity between network components. Following validation, the data is processed using an automated modelling tool to generate 3D solids from 2D geometric representations. These solids are then integrated into BIM models to facilitate compatibility with 3D workflows and enable detailed spatial analyses.
The workflow contributes to improved spatial understanding by visualizing the relationships between utilities and other infrastructure elements. The automation of validation and modeling processes ensures consistent and accurate outputs, minimizing errors and increasing workflow efficiency.
This methodology highlights the application of FME in addressing challenges associated with geospatial data transformation and demonstrates its utility in enhancing data integration within BIM frameworks. By enabling accurate 3D representation of utility networks, the workflow supports improved design collaboration and decision-making in complex infrastructure projects
