This document provides a summary of Peter Lubbers' presentation on building real-time applications with HTML5 Web Sockets. The presentation discussed the limitations of HTTP for real-time applications and techniques like polling and long polling that were used. It introduced HTML5 technologies like Web Sockets and Server-Sent Events that allow for true real-time, bidirectional communication. Web Sockets establish a single TCP connection and allow full-duplex messaging with very small overhead. This dramatically reduces network traffic compared to polling-based approaches. The presentation covered the Web Sockets protocol and APIs available in browsers.
HTML5 WebSocket for the Real-Time Weband the Internet of ThingsPeter Moskovits
Abstract: In his talk Peter gives a brief introduction to WebSocket and discusses how real-time Web communications technologies can be applied to an always connected Web and mobile world. Then, he walks you through how to provide interactivity and collaboration by controlling physical objects remotely. The presentation features several live demonstrations of the concepts discussed throughout the session.

WebSocket is not just a push mechanism. There are other HTTP-based mechanisms for simply sending a short notification to the browsers. It is much more. This presentation was given at both JavaOne 2015 and HTML5DevConf 2015 with slightly different Java/JavaScript information, but the basic information is the same.

Html5 web sockets - Brad Drysdale - London Web 2011-10-20Nathan O'Hanlon
This month we focus in on WebSockets in HTML5 with Brad Drysdale.
You're probably aware of the various chat systems around the web (facebook chat for example) but recently there has been more of a desire for other types of interaction using these technologies. Many have requested talks on Node.js, Comet long-polling, or similar technologies. WebSockets are the evolution of these technologies, and a developing standard being progressed by the IETF.
The HTML 5 standard specifies new APIs for storage, drawing, drag-and-drop, and other areas that have made web programming painful. Browsers have already begun incorporating parts of HTML 5 (canvas, for example) even though the specification is far from complete. The HTML 5 Communication section includes two additional connectivity features: Server-Sent Events, a standardization of HTTP push, and Web Sockets, a cross-domain safe, full-duplex connection. Server-Sent Events will make real-time updates and notifications easy, and Web Sockets provide the functionality necessary to build chat for the web without the previously required hackery.
Come and hear the latest on what this great technology allows!
Brad Drysdale is the Technical Director in EMEA for Kaazing. Brad has also worked at Openwave and Netscape Communications in various pre-sales and technical evangelist roles.
Developing Revolutionary Web Applications using Comet and Ajax PushDoris Chen
Join the asynchronous web revolution! Because Ajax-based applications are almost becoming the de facto technology for designing web-based applications, it is more and more important that such applications react on the fly, or in real time, to both client and server events. AJAX can be used to allow the browser to request information from the web server, but does not allow a server to push updates to a browser. Comet solves this problem. Comet is a technology that enables web clients and web servers to communicate asynchronously, allowing real-time operations and functions previously unheard of with traditional web applications to approach the capabilities of desktop applications. This session will start to provide an brief introduction to the asynchronous web, AJAX polling, long polling, and Streaming, explaining the Bayeux protocol, Cometd, Grizzly Comet implementation on GlassFish. Different approaches and best practices to develop comet application will also be discussed. You will learn how to develop the chat application, how to implement distance learning slideshow application, how to manage a chat application from the server and how to develop a two-player distributed game application. Attendees will take away the tactics they need in order to add multiuser collaboration, notification and other Comet features to their application, whether they develop with Dojo, jQuery, jMaki, or Prototype and whether they deploy on Jetty, Tomcat, or the GlassFish Application Server.

HiveMQ + Kafka: The ideal solution for IoT MQTT data integrationMargarethaErber
Many companies want to move MQTT data between IoT devices and Kafka clusters connected to back-end enterprise systems. However, connecting thousands or even millions of IoT devices over unreliable networks and providing end-to-end persistent messaging guarantees can create some challenges.
HiveMQ has created a solution that allows for easy bi-direction MQTT message flow between IoT devices and Kafka clusters.
This presentation describes the technical challenges of connecting IoT devices to Apache Kafka and how the HiveMQ Kafka solution solves these problems.

Brushing skills on SignalR for ASP.NET developersONE BCG
Let’s take a quick peek at SignalR and how we use it.
SignalR is an open-source library available in ASP.NET, to help developers add real-time features in web applications and more. Chat is the most common application that you can think of, there is a lot more you can do.
SignalR can be used to add any sort of “real-time” web functionality like dashboards, collaborative tools that require simultaneous editing of documents, job progress updates, and real-time forms. It can enable completely new types of web applications that need high-frequency updates from the server. One of the most common examples is real-time gaming.
IoT is becoming more pervasive, and it is a crucial part of digital transformation initiatives across industries. Knowing the essential building blocks can help you in your journey.
The first step towards this journey is learning about the de-facto standard for IoT messaging, MQTT, which helps reliably connect devices and efficiently move data bidirectionally between them even in unreliable networks.
Here're the webinar slides where Mary Grygleski walks you through MQTT history, some of the key features of this lightweight IoT protocol, and how it can be used for several IoT and IIoT use cases.
About the Speaker.

Topic of Presentation: Optimising TCP in today’s changing network environment
Language: English
Abstract: The need to juggle performance across wired, wireless and wi-fi networks is a challenge as each of these paths has very different characteristics when it comes to TCP. Tuning the TCP stack to be optimized for the varying degrees of packet loss, latency and congestion on the different connection types is a challenge. This session will cover tuning several aspects of your network and the underlying TCP stack to deliver an optimized application experience for all users. Topics will include:
Choosing the correct Congestion Control algorithm
Optimizing TCP with techniques like TCP buffering and adjusting TCP window sizes
Rate-based pacing to help multiple request/responses over a single connection

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.
