Progressive Enhancement with JavaScript and Ajax
Progressive Enhancement with JavaScript and AjaxChristian Heilmann The document discusses progressive enhancement with JavaScript and Ajax. It defines progressive enhancement as testing for support of different technologies like JavaScript, DOM, and objects, and providing alternative interfaces when something is not supported. It recommends testing for dependencies before using them, and separating interfaces from styles using CSS for flexibility. While CSS-only solutions seem appealing, JavaScript is more powerful and reliable for building complex, accessible interfaces. The key is enhancing interfaces thoughtfully to improve the user experience, not just for the sake of enhancement.

Asynchronous JavaScript and XML (AJAX) is a set of web development techniques that allow web pages to be updated asynchronously by exchanging data with a web server behind the scenes, without reloading the entire page. jQuery is a popular JavaScript library that simplifies tasks like HTML document traversal and manipulation, events, animations, and Ajax interactions for rapid web development.
Advancing JavaScript with Libraries (Yahoo Tech Talk)
Advancing JavaScript with Libraries (Yahoo Tech Talk)jeresig 1. JavaScript libraries abstract away browser differences and complex DOM APIs to provide simpler, more consistent interfaces.
2. New library patterns that emerged like DOM selectors and behaviors advanced development by managing cross-browser issues and establishing expectations around DOM manipulation.
3. Libraries build upon one another, with higher-level "meta-libraries" and domain-specific languages creating new programming paradigms on top of existing libraries and APIs.
The Theory Of The Dom
The Theory Of The Domkaven yan - The original vision of the World Wide Web was as a hyperlinked document retrieval system, not for presentation, sessions, or interactivity. If it had stayed true to this vision, modern sites like Yahoo would not exist.
- Browser wars in the 1990s led to proprietary technologies that frustrated developers. The introduction of JavaScript in 1995 allowed for dynamic and interactive web pages.
- By the 2000s, Microsoft's Internet Explorer dominated the browser market, bringing some stability through standards like DOM and DHTML. However, cross-browser differences still posed challenges for developers.

ScaleFail
ScaleFailSimon Willison This document summarizes the steps taken to optimize the performance of a website for reviewing parliamentary expenses. Initially, querying for unreviewed pages was causing high CPU usage on the database server. To address this, the count of unreviewed pages was cached in Memcached, reducing CPU usage. Other optimizations included migrating the database to InnoDB, adding a "next" button that redirects to a random unreviewed page, and caching the list of unreviewed page IDs in Memcached for faster random access. During a future scale issue, Redis will be used instead of Memcached. Putting the site in read-only mode also helped during a period of high load.

Reducing Conflicts and Increasing Safety Along the Cycling Networks of East-F...Safe Software In partnership with the Belgian Province of East-Flanders this project aimed to reduce conflicts and increase safety along a cycling route between the cities of Oudenaarde and Ghent. To achieve this goal, the current cycling network data needed some extra key information, including: Speed limits for segments, Access restrictions for different users (pedestrians, cyclists, motor vehicles, etc.), Priority rules at intersections. Using a 360° camera and GPS mounted on a measuring bicycle, we collected images of traffic signs and ground markings along the cycling lanes building up mobile mapping data. Image recognition technologies identified the road signs, creating a dataset with their locations and codes. The data processing entailed three FME workspaces. These included identifying valid intersections with other networks (e.g., roads, railways), creating a topological network between segments and intersections and linking road signs to segments and intersections based on proximity and orientation. Additional features, such as speed zones, inheritance of speed and access to neighbouring segments were also implemented to further enhance the data. The final results were visualized in ArcGIS, enabling analysis for the end users. The project provided them with key insights, including statistics on accessible road segments, speed limits, and intersection priorities. These will make the cycling paths more safe and uniform, by reducing conflicts between users.

Integration of Utility Data into 3D BIM Models Using a 3D Solids Modeling Wor...
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
