EWD 3 Training Course Part 15: Using a Framework other than jQuery with QEWDRob Tweed
This document discusses using QEWD, a framework for building real-time web applications, with frameworks other than jQuery. It states that QEWD is framework agnostic and can be used with any framework like Angular, React, Ember, and ExtJS. It provides an example of integrating QEWD with ExtJS by starting EWD after the DOM loads and handling the ewd-registered event to send messages to the backend. It also notes there are separate slide decks on using QEWD specifically with React.
EWD 3 Training Course Part 36: Accessing REST and Web Services from a QEWD ap...Rob Tweed
This document describes how to create a REST proxy using QEWD. It involves:
1. Amending the backend restDemo.js module to extract the REST call logic into a separate function and define a 'proxy' handler function.
2. Setting the module to be a REST module.
3. Having the proxy handler function invoke the extracted REST call logic to proxy requests to the actual REST service.
4. Adding a route in the QEWD startup file to route the /api/proxy URL to the proxy handler function, exposing the REST service via the proxy.
This allows the module to act as a REST proxy to the external JSONPlaceholder service while still supporting normal interactive apps

This document discusses different techniques for managing state in web applications:
- Cookies store name-value pairs on the client-side and accompany HTTP requests/responses to persist user information across sessions. They can be session-based or persistent.
- Serialization converts objects to binary strings for storage or transmission. Classes need to implement the Serializable interface.
- Session state stores serialized objects on the server for each user session. It relies on session IDs transmitted via cookies or URLs.
- HTML5 Web storage APIs like localStorage and sessionStorage store data client-side instead of transmitting with each request. localStorage persists across sessions while sessionStorage lasts one session.
- Caching locally stores files

Building a Global-Scale Multi-Tenant Cloud Platform on AWS and Docker: Lesson...Felix Gessert
In this talk we share the lessons learned while building out the Baqend Cloud platform on AWS and Docker. Baqend’s AWS-hosted architecture consists of a caching CDN-Layer, global and local load balancing, a group of REST and Node.js servers and a database cluster with Redis and MongoDB. As customers have their own set of containerized REST and Node servers, we needed a cluster that on the one hand is horizontally scalable and on the other hand easily manageable and fault-tolerant from an operational perspective. Today there are at least 4 popular systems that claim to support this:
- Kubernetes
- Apache Mesos
- Docker Swarm
- AWS Elastic Container Service (ECS)
Thinking that ECS would certainly be the easiest option on AWS, we started building our cluster on it. We quickly came to realize that while ECS was astoundingly stable and easy to use there were inherent limitations that could not be worked around. An old Docker version, missing network isolation, no means of parameterizing task and forced memory constraints are major limitations of ECS we will talk about. Seeing the daunting operational overhead of running Kubernetes or Mesos in practice we turned to Docker’s native clustering solution Swarm. We will present how Swarm works with both Docker and AWS and highlight the advantages and downsides compared to Amazon’s ECS.

The presentation will cover challenges for web server farms without caching, an overview of Velocity's architecture and features, different caching strategies in Velocity including partitioned and replicated caches, and best practices for developing a caching strategy and using Velocity.
This document discusses session management in PHP. It explains that PHP sessions and cookies allow for persistence in HTTP, which is otherwise stateless. Sessions store user information on the server and allow sharing data across requests. The session ID associates a user's requests. Sessions are created via session_start() and values are stored in the $_SESSION superglobal array and retrieved the same way. Sessions can be destroyed via session_destroy() but are normally left to timeout. An example increments a session variable to count page accesses.

Extending Build to the Client: A Maven User's Guide to Grunt.jsPetr Jiricka
This document discusses moving from a Maven-only build process to using both Maven and Grunt.js for builds. It introduces Node.js, Bower, and Grunt.js as tools for managing client-side dependencies and tasks. Grunt.js plugins are used to add tasks for compiling Sass to CSS, minifying and concatenating JavaScript and CSS, running unit tests with Karma, and watching for changes. The workflow in both the command line and NetBeans IDE is covered.
Matteo Moretti discusses scaling PHP applications. He covers scaling the web server, sessions, database, filesystem, asynchronous tasks, and logging. The key aspects are decoupling services, using caching, moving to external services like Redis, S3, and RabbitMQ, and allowing those services to scale automatically using techniques like auto-scaling. Sharding the database is difficult to implement and should only be done if really needed.
Rami Jarvinen discusses optimizing performance on Drupal sites. He outlines several caching strategies including PHP opcode caching, Drupal internal caching, page caching, and reverse proxy caching using Boost or Varnish. Memcached can be used as a high-performance replacement for Drupal's database caching. Scaling can involve using a master-slave database setup and serving static files from a separate server. Profiling tools can identify SQL bottlenecks and unnecessary queries for optimization. The optimal solution depends on factors like the number of anonymous vs logged-in users and the capabilities of the hosting environment.

LNUG: Having Your Node.js Cake and Eating It TooRob Tweed
The document discusses using Node.js for server-side applications. It introduces QEWD, a Node.js platform that allows running code in isolated worker processes to avoid Node.js's concurrency issues. QEWD uses a master process to queue incoming requests and dispatch them to separate worker processes. This allows Node.js code to leverage synchronous logic and avoid CPU-intensive tasks blocking other requests. The document argues this allows developers to "have their Node.js cake and eat it" by using Node.js for all application needs.

Streamlining End-to-End Testing Automation with Azure DevOps Build & Release Pipelines
Automating end-to-end (e2e) test for Android and iOS native apps, and web apps, within Azure build and release pipelines, poses several challenges. This session dives into the key challenges and the repeatable solutions implemented across multiple teams at a leading Indian telecom disruptor, renowned for its affordable 4G/5G services, digital platforms, and broadband connectivity.
Challenge #1. Ensuring Test Environment Consistency: Establishing a standardized test execution environment across hundreds of Azure DevOps agents is crucial for achieving dependable testing results. This uniformity must seamlessly span from Build pipelines to various stages of the Release pipeline.
Challenge #2. Coordinated Test Execution Across Environments: Executing distinct subsets of tests using the same automation framework across diverse environments, such as the build pipeline and specific stages of the Release Pipeline, demands flexible and cohesive approaches.
Challenge #3. Testing on Linux-based Azure DevOps Agents: Conducting tests, particularly for web and native apps, on Azure DevOps Linux agents lacking browser or device connectivity presents specific challenges in attaining thorough testing coverage.
This session delves into how these challenges were addressed through:
1. Automate the setup of essential dependencies to ensure a consistent testing environment.
2. Create standardized templates for executing API tests, API workflow tests, and end-to-end tests in the Build pipeline, streamlining the testing process.
3. Implement task groups in Release pipeline stages to facilitate the execution of tests, ensuring consistency and efficiency across deployment phases.
4. Deploy browsers within Docker containers for web application testing, enhancing portability and scalability of testing environments.
5. Leverage diverse device farms dedicated to Android, iOS, and browser testing to cover a wide range of platforms and devices.
6. Integrate AI technology, such as Applitools Visual AI and Ultrafast Grid, to automate test execution and validation, improving accuracy and efficiency.
7. Utilize AI/ML-powered central test automation reporting server through platforms like reportportal.io, providing consolidated and real-time insights into test performance and issues.
These solutions not only facilitate comprehensive testing across platforms but also promote the principles of shift-left testing, enabling early feedback, implementing quality gates, and ensuring repeatability. By adopting these techniques, teams can effectively automate and execute tests, accelerating software delivery while upholding high-quality standards across Android, iOS, and web applications.
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Speaker:
- Jianjian Xie (Staff Software Engineer, Alluxio)
As Trino users increasingly rely on cloud object storage for retrieving data, speed and cloud cost have become major challenges. The separation of compute and storage creates latency challenges when querying datasets; scanning data between storage and compute tiers becomes I/O bound. On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache
- Real-world cases, including a large online payment firm and a top ridesharing company
- The future roadmap of Trino file system cache and Trino-Alluxio integration
