Introduction to Web Worker
•
0 likes•779 views
Web workers allow JavaScript to use multiple threads to improve performance of heavy tasks by running them in background threads instead of the main thread so as not to block the user interface. This helps solve issues like applications becoming unresponsive when busy. There are different types of workers including dedicated workers for separate threads, shared workers for shared threads across contexts, and service workers which act as proxies to allow caching of assets for offline use.

Immutable infrastructure isn’t the answer
Immutable infrastructure wasn't suitable for the consultancy's needs as it led to long deployment times and a lack of visibility into instance configurations. Instead, they developed a hybrid approach using Packer, Puppet, S3, and AWS services that provides faster deployments, self-healing infrastructure, and a known, verifiable state for instances. This allows them to focus on application development rather than infrastructure management.

Lightweight webdev
The document summarizes a presentation on lightweight web development using ASP.NET MVC, AJAX, WCF, jQuery, and jTemplates. It discusses moving away from ViewState in ASP.NET towards the MVC pattern, using WCF for services, and a RESTful approach consuming a WCF API with jQuery and jTemplates to separate the UI from server-side concerns. It also covers advantages like code reuse, flexibility, and less code to maintain.
Why akka
Akka is an open source toolkit for building highly concurrent, distributed, and fault-tolerant applications on the JVM. It uses the actor model and software transactional memory to provide a higher level of abstraction for writing scalable applications compared to lower-level concurrency primitives. Akka embraces the "let it crash" model of fault tolerance used in telecom to build self-healing systems and aims to make building reliable distributed systems easier.
Ember STL Meetup - Lazy Loading using Brunch
The document discusses lazy loading in EmberJS applications using Brunch to improve performance. It describes dividing code into a main file containing globally necessary components and route-specific files containing controllers, templates, and other dependencies. Routes specify which components to asynchronously load using require after the beforeModel hook. An example Brunch configuration, LazyLoaderMixin, and route are provided. Results from a test site showed the main app.js file decreased significantly in size, and page load times improved by around 5 seconds.
Ember.js: Jump Start
Ember.js is an open-source client-side JavaScript web application framework based on the model-view-controller (MVC) software architectural pattern. It allows developers to create scalable single-page applications by incorporating common idioms and best practices into a framework.
"Framework Principal" pattern
This document discusses the "Framework Principal" pattern which allows optimizing resource usage across multiple applications by initializing shared services and configurations in a single starter class. The Framework Principal runs very early and can be used to launch services independently of any application based on configuration properties. It provides examples of how to configure different applications to use the same Framework Principal by specifying different property files and user names for production vs sandbox environments. This allows launching shared services only once across multiple applications rather than separately in each one.
WebAssembly vs JavaScript: What is faster?
- WebAssembly is a new low-level compilation target that runs at native speed by taking advantage of common hardware capabilities available on a web platform.
- While WebAssembly is very fast for pure computations, calling JavaScript from WebAssembly can lead to slowdowns. Interacting with the DOM or host APIs may also be slower than native code.
- WebAssembly is best suited for applications that require a lot of computation, are developed with a focus on performance, and have minimal interactions with JavaScript or the DOM. This includes porting existing C/C++ libraries and algorithms to the web.

The document also covers PHP syntax and concludes by asking if there are any questions.
Single Page Apps
Single page applications (SPAs) allow for faster, more responsive web apps by moving more processing to the client side. SPAs avoid full page refreshes by downloading only necessary features and using client-side MVC. This improves the user experience through reduced loading times, bandwidth usage, and roundtrips compared to traditional server-side MVC. However, SPAs require more initial effort due to JavaScript knowledge and implementing services on the server.

Lessons Learnt in 2009
This document provides lessons learned from a presentation on Ruby on Rails development. It discusses using Ruby Enterprise Edition for faster tests. It recommends using factories over fixtures for test data and advocates writing more integration tests than unit tests. It also covers improving security with the rails_xss plugin, using MessageVerifier for authentication, and asynchronous job processing with Delayed Job. Methods for scaling file uploads using mod_porter and pagination without offsets are presented. The document aims to help Ruby web developers with performance, security, background processing, and scaling.
Client server 01
This document provides an introduction to web programming with Java. It discusses the past, present, and future of servlets and JSPs. It outlines the objectives of the course, which are to introduce web applications, three approaches to Java web development (servlets/JSPs, JSF, and Spring Framework), and servlet/JSP web development specifically. It also describes the typical components and architecture of a servlet/JSP application, including the web and database servers, directories, and tools used.
Single page App
Web applications have evolved over time from traditional multi-page applications that required full page reloads to modern single-page applications (SPAs) that function more like desktop apps. SPAs are built with JavaScript frameworks on the client-side and use Ajax techniques to update parts of the page dynamically without reloading. This provides a more fluid user experience compared to older request-response models. SPAs can improve performance by reducing load times, transferring less data, distributing load to clients, and enabling easier caching compared to traditional server-side web apps.
Single Page Applications: Your Browser is the OS!
Single Page Applications have gained tremendous popularity over the past few years and have prompted the creation of several frameworks to support their development. Unlike traditional web applications, most of the heavy lifting for SPA happens on the client side in your web browser. These applications rely on hundreds of lines of JavaScript coupled with asynchronous web service calls to provide a desktop-like experience that is accessible from virtually any device.
Join Principal Architect, Jeremy Likness, to learn more about SPA, including how to determine when you should choose this approach, how SPA compares and contrasts with traditional server-based approaches including ASP.NET WebForms and MVC, and what frameworks and tools (such as jQuery, AngularJS, and Aurelia) make building SPA easier.

The goal of MicroProfile is to optimise Java EE for a micro-service architecture. It is based on some of the Java EE specifications and standardise a few technologies from the micro-services space.
However, some of the MicroProfile implementations are completely different 'servers', like the KumuluzEE server. So how can you migrate easily from your favorite Java EE server to a MicroProfile implementation?
This session shows you an overview of what MicroProfile.IO is and how it relates to Java EE. It then demonstrates with a few examples how you can adjust your Java EE application to incorporate some of the MicroProfile.IO specifications and how you can transform your Java EE application to a MicroProfile.IO one using Thorntail, Payara Micro, and KumuluzEE.
Gradual migration to MicroProfile
This document discusses gradually migrating Java EE applications to use MicroProfile features. It presents two options for the migration: 1) Adding MicroProfile implementations to an existing Java EE server or 2) Using a Java EE server that integrates MicroProfile implementations. The document demonstrates migrating a sample mortgage application first using Thorntail and then Payara Micro. It highlights some issues that may occur and advantages of each approach.
My site is slow
Drupal is a powerful and flexible platform to build websites with rich funcionalities without building almost anything from scratch. This flexibility brought by the usage of a powerful framework and the work of a super active community can abstract people to understand what is Drupal doing behind the scenes.
Most of performance talks regarding Drupal focus on aspects like infrastructure changes, caching strategies, and comparison of performance between modules or platforms. Unfortunately when performance problems occur, development teams also follow several strategies to replace several aspects in their platforms, jump directly to look for slow queries before trying really to understand where is the bottleneck.
However, most of the times what really needs to be done is to look to what the application is doing and understanding why is it taking so long to do it. Drupal is a platform used by million of websites worldwide and its performance is easy to measure and compare.
At Acquia we have done dozens of performance assessments, and even if we usually face the same problems, sometimes we found weird situations that are only possible to be detected when measured. Measuring and profiling is the only way to understand performance problems in a site and provide valid fixes.
In this talk I will explain how to detect problems regarding performance in Drupal, using simple modules like devel, profilers like XhProf and looking to logs to understand the impact done on the application.

JMeter.ppt
JMeter is a tool for load and performance testing web applications. It was originally developed to test the Apache JServ project but now supports testing many server-based applications. The JMeter GUI provides a test plan where users can add thread groups, samplers, timers, listeners and other elements to build out functionality for load testing. Common elements include HTTP requests, assertions, and listeners to view results. The tool is easy to install, use and can record tests via a proxy server.
Jsp abes new
JSP (JavaServer Pages) allow embedding Java code within HTML/XML pages to create dynamic web content. Key points:
- JSP pages are compiled into Java servlets to generate the HTML response. This means JSP have access to full Java APIs and can be efficiently handled by the server.
- It is recommended to separate presentation logic in JSP from business logic in Java classes to improve modularity. This can be done using JavaBeans, tag libraries, and MVC pattern.
- Examples demonstrate using JSP scriplets and expressions to output dynamic data, JavaBeans to encapsulate data in reusable objects, and tag libraries to access beans and simplify JSP code. Form submission examples pass

La vita nella corsia di sorpasso; A tutta velocità, XPages!
Using XPages out of the box lets you build good looking and well performing applications. However, as XPage applications become bigger and more complex, performance can become an issue and, if it comes to scalability and speed optimization, there are a couple of things to take into consideration. Learn how to use partial refresh and partial execution mode and how to monitor its execution using a JSF LifeCycle monitor to avoid multiple re-calculation of controls. We will show tools that can allow you to profile your code, readily available from OpenNTF, along with a demonstration of how to use them to improve the speed of your code. Still writing SSJS and encounter a significant slow down when using Script Libraries? See, how you can improve the speed of your application using JAVA instead of JS, JSON and even @formulas.

Tiery Eyed
In this session we will take a look at several different methods for building tiered applications. Some of the tiering methodologies include Soap, XML-RPC, RESTful and multiple language architectures. The purpose of this talk will not be to determine which methodology is best, but instead will try to provide an unbiased view of the pros and cons of each.
Advanced Web Technology.pptx
This document provides an overview of advanced web technologies including callback functions, asynchronous JavaScript, promises, and async/await in JavaScript. It discusses full stack development using technologies like Node.js, Express, MongoDB, and AngularJS (MEAN stack). Key points include:
1) Callback functions allow a function to call another function, and a callback function can run after another function has finished. Asynchronous functions are often used with callbacks.
2) Promises provide an alternative to callbacks for handling asynchronous code in a cleaner way. A promise is an object that links producing and consuming code.
3) Async and await make promises easier to write by allowing asynchronous functions to be written like synchronous code.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
