This presentation discusses HTML 5 WebSockets and how they enable full-duplex communication in web applications, moving past limitations of traditional HTTP. The speakers are founders of Kaazing, which provides an open source HTML 5 WebSocket gateway. The presentation covers challenges with existing "Comet" techniques, and how WebSockets and Server-Sent Events in HTML 5 allow any TCP-based backend service to be accessed through a browser. A demo shows using WebSockets to build a real-time XMPP chat client.

introduction to web application development

FLYMAN TECHNOLOGY LIMITED

This document provides an introduction to web application development, including the history of the World Wide Web and how it works. It describes the basics of web clients and servers, URLs, HTML, and how communication is established over the internet. It then distinguishes between static and dynamic web pages, and discusses client-side scripting like JavaScript and Java applets as well as server-side scripting using languages like PHP, ASP, and JSP to generate dynamic web content. Finally, it lists some common web development tools.

WSDL in Mule Esb

Anand kalla

WSDL is an XML language used to describe web services, defining operations provided by the service, data formats, and location. It describes what a service does via operations, how it is accessed via protocols and data formats, and where it is located via URLs. A WSDL document defines types, messages, operations, bindings and services. Translators can generate code from WSDL or derive WSDL from existing code.

Link Header-based Invalidation of Caches

mikekelly

Gateway caches are intermediary components for reducing demands on destination servers, and therefore operational costs of a system. At scale, particularly with the advent of on-demand infrastructures such as EC2, etc., maximising cache efficiency translates into cost efficiency, resulting in a competitive advantage. In this position paper, we initially discuss advantages and limitations of HTTP caching mechanisms. We then propose to use HTTP Link: headers to maximise the efficiency of gateway (or reverse proxy) caching mechanisms and discuss early findings.

ZaloPay Merchant Platform on K8S on-premise

Chau Thanh

This document summarizes an incident and lessons learned from deploying a Kubernetes cluster on-premise to run the ZaloPay Merchant Platform. Key issues encountered included nodes breaking production after being scaled, multi-interface configuration challenges, and nodes failing to join the cluster. Lessons included practicing deployments, understanding root causes of failures, and ensuring business support for new technologies. Next steps outlined upgrading components, consolidating monitoring, improving alerts, and automating the CI/CD pipeline.

Introduction to WebSockets Presentation

Julien LaPointe

WebSockets allow for bidirectional communication between a client and server. They establish a persistent connection that allows real-time data transmission with low latency compared to HTTP. Socket.io makes WebSockets compatible across browsers by using the best available protocol. It works by having the client request an upgrade to WebSocket from an HTTP connection, establishing a full-duplex communication channel between client and server that stays open.

Clientside/Offline (onefile) Lecture Player in a Web Browser

Tokyo University of Science

Online portals for educational multimedia content are bottlenecks both in administrative and performance aspects. Administrative bottlenecks are the procedures required to upload and maintain content by creators, as well as shortages in functionality offered to clients. Performance bottlenecks are times when clients may not be able to view content because of server-side congestion. Client-side replay is a solution for both these problems. Educational material, with several types of multimedia content, can be packed into a single binary file which can later be opened, parsed, and replayed by a Javascript player inside the browser. A side feature is that such files can also be replayed offline from a file in local filesystem. This paper presents a prototype for such a player.

The document summarizes a case study of a blended learning program for branch managers that utilized formal and informal learning approaches. The program went through several phases: needs assessment, setting objectives, program design including a syllabus and activities, and implementation using various technologies. It evaluated results and made recommendations. Barriers included buy-in from HR and IT challenges. The program promoted informal learning through activities like international conversations on Skype and simulations in a virtual classroom.

Present Perfect Versus Past Tense

Buthaina AlOthman

The document discusses the differences between using the present perfect and past tense. The present perfect is used to describe something that is still true now, while the past tense describes something that is no longer true. The present perfect can introduce general ideas, while the past tense provides specific details. The present perfect is also used when the specific time of an event is not mentioned, and the experience is more important than when it occurred.

Multi-Lingual Accumulo Communications

Accumulo Summit

A completely native Accumulo connector was developed from 2012-2014 called Sharkbite. During this time, many native functions were built into a C++ client that avoided issues with the proxy and connects directly to internal services, effectively providing access to data without the need for a proxy or JAVA client. In this presentation we'll dive into the design of this C++ client and accessing it from multiple language connectors without the overhead of establishing one or more proxies. We'll close with performance evaluations of the JAVA client, proxied client, and the Accumulo connector.

To Kill a Monolith: Slaying the Demons of a Monolith with Node.js Microservic...

Tony Erwin

Originally presented at CF Summit Europe 2017 in Basel, Switzerland. The abstract of the talk was: The Bluemix UI (which runs on CloudFoundry) is the front-end to Bluemix, IBM’s open cloud hosting platform. The original implementation as a single-page, monolithic Java web app brought with it many demons, such as poor performance, lack of scalability, inability to push small updates, and difficulty for other teams to contribute code. Over the last 2 years, the team has been on a mission to slay these demons by embracing cloud native principles and splitting the monolith into smaller Node.js microservices. The effort to migrate to a more modern and scalable architecture has paid large dividends, but has also left behind a few battle scars from wrestling with the added complexity cloud native can bring. The team had to tackle problems in a wide variety of areas, including: large-scale deployments, continuous integration, monitoring, problem determination, high availability, and security. Tony Erwin will discuss the advantages of microservice architectures, ways that Node.js has increased developer productivity, approaches to phasing microservices into a live product, and real-life lessons learned in the deployment and management of Node.js microservices across multiple CloudFoundry environments. His war stories will prepare you to wage your own battles against monoliths everywhere -- happy slaying!

Essentials of Automations: Exploring Attributes & Automation Parameters

Safe Software

Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they? Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality. You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Dandelion Hashtable: beyond billion requests per second on a commodity server

Antonios Katsarakis

This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Mutation Testing for Task-Oriented Chatbots

Pablo Gómez Abajo

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots. To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
