JavaScript shell scripting

Mar 28, 201114 likes6,057 views

JavaScript can be used for many purposes including shell scripting with Windows Script Host (WSH), monitoring and debugging HTTP requests with HTTPWatch, and programmatically interacting with the browser DOM and making HTTP requests with different browsers like Internet Explorer and Firefox. The document demonstrates how to use JavaScript with WSH, HTTPWatch, and the browser DOM to inspect and modify HTTP requests and the DOM structure.

JavaScript Performance PatternsStoyan Stefanov

JavaScript performance patterns focuses on optimizing JavaScript loading and execution for better performance. Some key points include reducing the number of script files, leveraging caching, minification and compression. Asynchronous loading helps prevent blocking. DOM operations are expensive so it's important to cache references, batch operations and avoid reflows. Data attributes provide a convenient way to store data on elements. Shims and polyfills should be used judiciously, loading conditionally where native support is limited. Benchmarking is crucial to identify real bottlenecks and measure impact of optimizations.

Hierarchical data models in Relational Databasesnavicorevn

This document discusses different approaches for implementing hierarchical data models in relational databases. It begins by outlining the controversy around representing hierarchical data in relational systems and perceptions of reality through data modeling. It then examines logical entity-relationship diagrams for representing generalization hierarchies and explores various physical implementations, including the entity-attribute-value model, null-able attributes tables, vertical and horizontal partitioning, and hybrid approaches. Guidelines are provided for each implementation and their tradeoffs are discussed.

Trees In The Database - Advanced data structuresLorenzo Alberton

Storing tree structures in a bi-dimensional table has always been problematic. The simplest tree models are usually quite inefficient, while more complex ones aren't necessarily better. In this talk I briefly go through the most used models (adjacency list, materialized path, nested sets) and introduce some more advanced ones belonging to the nested intervals family (Farey algorithm, Continued Fractions, and other encodings). I describe the advantages and pitfalls of each model, some proprietary solutions (e.g. Oracle's CONNECT BY) and one of the SQL Standard's upcoming features, Common Table Expressions.

JavaScript for PHP developersStoyan Stefanov

This document provides an overview of JavaScript for PHP developers. It compares the syntax and core concepts between the two languages. Some of the key points covered include: variables and data types are similar, functions are objects in JavaScript, JavaScript uses prototypes instead of classes, and functions provide scope. The document also summarizes the built-in global functions and properties, common methods for objects like Array and String, and emphasizes that constructor functions are often not needed in JavaScript.

High Performance Social PluginsStoyan Stefanov

Social plugins are third-party iframes that allow users to interact with social features like liking or sharing content. They can be plugged in two main ways: 1) by writing the iframe directly or 2) by loading third-party JavaScript that generates the iframe. The third-party JavaScript should be loaded asynchronously to avoid blocking the page load. Once loaded, the social plugin needs to show up quickly with a single request, resize itself if needed, and handle user interactions like likes in a lazy manner by preloading JavaScript but not evaluating it until an interaction occurs.

Progressive Downloads and Rendering - take #2Stoyan Stefanov

Progressive Downloads and RenderingStoyan Stefanov

Progressive downloads and rendering allow content to be delivered and displayed to the user incrementally to improve perceived performance. JavaScript should be placed at the bottom of the page to avoid blocking. CSS can block rendering so should also be delivered non-blocking when possible. Techniques like flushing output, non-blocking scripts, and data URIs can help deliver content progressively. MHTML and preloading can help optimize delivery across multiple HTTP requests. The overall goal is to start displaying content as soon as possible while content continues downloading in the background.

Performance patternsStoyan Stefanov

The document discusses various patterns and techniques for improving JavaScript performance, including: 1. Loading scripts asynchronously and deferring execution to improve perceived page load times. 2. Using local variables instead of globals to reduce scope chain lookups and improve minification. 3. Caching expensive operations through memoization and reusing initialization code to avoid redundant work. 4. Avoiding direct DOM access in loops to reduce reflows and repaints, such as building up a string instead of multiple innerHTML assignments.

So what's next to do? Well, you can cheat! You know that time is relative - one hour with your mother-in-law feels much longer than one hour on the beach. The same way you can bend the perception of the page loading time and make the page feel faster, even though the RTT is the same.

The business of performanceStoyan Stefanov

Faster website loading speeds directly correlate to increased user satisfaction and business metrics like revenue and traffic. Studies show even small improvements in speed, like reducing load times by 1 second, can increase conversion rates by 2.8-4.3%. Slower sites see 5-9% drops in full page traffic and less repeat visits. Focusing page optimizations on front-end components, which account for most load time, can yield the biggest gains like Shopzilla saw moving from 6 to 1.2 seconds and Netflix reducing outbound traffic 43% with compression.

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

Enabling BIM / GIS integrations with Other Systems with FMESafe Software

Jacobs has successfully utilized FME to tackle the complexities of integrating diverse data sources in a confidential $1 billion campus improvement project. The project aimed to create a comprehensive digital twin by merging Building Information Modeling (BIM) data, Construction Operations Building Information Exchange (COBie) data, and various other data sources into a unified Geographic Information System (GIS) platform. The challenge lay in the disparate nature of these data sources, which were siloed and incompatible with each other, hindering efficient data management and decision-making processes. To address this, Jacobs leveraged FME to automate the extraction, transformation, and loading (ETL) of data between ArcGIS Indoors and IBM Maximo. This process ensured accurate transfer of maintainable asset and work order data, creating a comprehensive 2D and 3D representation of the campus for Facility Management. FME's server capabilities enabled real-time updates and synchronization between ArcGIS Indoors and Maximo, facilitating automatic updates of asset information and work orders. Additionally, Survey123 forms allowed field personnel to capture and submit data directly from their mobile devices, triggering FME workflows via webhooks for real-time data updates. This seamless integration has significantly enhanced data management, improved decision-making processes, and ensured data consistency across the project lifecycle.

Artificial Intelligence is rapidly integrating into every aspect of technology. While the neural processing unit (NPU) often receives the majority of the spotlight as the ultimate AI problem solver, it is essential to recognize that not all AI workloads can be efficiently executed on an NPU and that neural network architectures are evolving rapidly. To create efficient chips and systems with market longevity, designers must plan for diverse AI workloads that include networks yet to be invented. In this presentation, Borkar introduces a new processor from Cadence Tensilica. This new solution is designed to complement any NPU, creating the perfect synergy between the two processing engines and establishing a robust AI subsystem able to efficiently support workloads yet to be encountered. This combination allows developers to achieve efficiency and performance on the AI workloads of today and tomorrow, paving the way for future innovations in AI-powered devices.
