JWT (JSON Web Token) is a standard used to securely transmit information between parties as a JSON object. It allows servers to verify transmitted information without storing state on the server, making it more scalable. JWTs provide authentication and authorization by encoding claims about an entity (such as an user) including an ID, expiration time, and other data inside the token itself.
Explaining the benefits of using WebSockets, the difference comparing with Ajax and explaining the code we should write on both ends. The server and the client.

1) WebSockets allow for bidirectional communication between a client and server that overcomes limitations of HTTP such as polling. It uses a single TCP connection for sending messages back and forth.
2) The WebSocket handshake establishes a connection via HTTP that is then switched to the WebSocket protocol. Messages can then be sent simultaneously in both directions.
3) Compared to polling, WebSockets have much lower overhead since it uses a single connection rather than multiple HTTP requests, resulting in significantly lower bandwidth usage even with many connected clients.
OAuth 2.0 is an open authentication and authorization protocol which enables applications to access each others data. This talk will presents how to implement the OAuth2 definitions to secure RESTful resources developed using JAX-RS in the Java EE platform.
Measuring Real User Performance in the BrowserNicholas Jansma
To people responsible for the health of web properties, monitoring, measurement, and analysis of real-user experiences is key to delivering a consistent and delightful experience. Drawing on their experience with the open source boomerang project, Philip Tellis and Nic Jansma explore various tools and methods available to measure real-user performance in the browser.
Topics include:
Available browser APIs: Navigation Timing, Resource Timing (Levels 1 and 2), User Timing, Error Logging, and more
Measuring full-page apps
Measuring single-page apps
RUM SpeedIndex
Measuring continuity
Hacks when an API isn’t available
Avoiding the observer effect
Filtering data to get rid of noise
Identifying outliers and treating them differently
Responsiveness to user interaction is crucial for users of web apps, and businesses need to be able to measure responsiveness so they can be confident that their users are happy. Unfortunately, users are regularly bogged down by frustrations such as a delayed "time to interactive” during page load, high or variable input latency on critical interaction events (tap, click, scroll, etc.), and janky animations or scrolling. These negative experiences turn away visitors, affecting the bottom line. Sites that include third-party content (ads, social plugins, etc.) are frequently the worst offenders.
The culprit behind all these responsiveness issues are “long tasks," which monopolize the UI thread for extended periods and block other critical tasks from executing. Developers lack the necessary APIs and tools to measure and gain insight into such problems in the wild and are essentially flying blind trying to figure out what the main offenders are. While developers are able to measure some aspects of responsiveness, it’s often not in a reliable, performant, or “good citizen” way, and it’s near impossible to correctly identify the perpetrators.
Shubhie Panicker and Nic Jansma share new web performance APIs that enable developers to reliably measure responsiveness and correctly identify first- and third-party culprits for bad experiences. Shubhie and Nic dive into real-user measurement (RUM) web performance APIs they have developed: standardized web platform APIs such as Long Tasks as well as JavaScript APIs that build atop platform APIs, such as Time To Interactive. Shubhie and Nic then compare these measurements to business metrics using real-world data and demonstrate how web developers can detect issues and reliably measure responsiveness in the wild—both at page load and postload—and thwart the culprits, showing you how to gather the data you need to hold your third-party scripts accountable.

What are JSON Web Tokens and Why Should I Care?Derek Edwards
In this talk originally presented at the San Diego Javascript meetup on December 3rd 2014, I explain how JSON Web Tokens can be used as a replacement for session/cookie-based user authentication in modern web applications.
Since web applications are increasingly leveraging client-side MVC frameworks such as Ember.JS, Angular and Backbone, traditional authentication schemes that leverage cookies are less desirable. I explain the key challenges with traditional authentication schemes and how JWT can be used as a very clean alternative.
Java and the blockchain - introducing web3jConor Svensson
An overview of what blockchain is, how the Ethereum blockchain works, and how you can deploy and interact with smart contracts on Ethereum, all from within the JVM, thanks to web3j.
The speaker share his vision on the prospects of employing the technology for practical tasks. He presented basics of the blockchain architecture with case studies of JavaScript blockchain implementation using Node.js.
This presentation by Valerii Radchenko (Senior Software Engineer, Consultant, GlobalLogic, Kharkiv) was delivered at GlobalLogic Kharkiv JS TechTalk #2 on August 17, 2018.
This document discusses JSON Web Tokens (JWT) for authentication. It begins by explaining the need for authorization in web applications and how token-based authentication addresses issues with server-based authentication. The structure of a JWT is described as a JSON object with a header, payload, and signature. Python libraries for working with JWT like PyJWT, Django REST Framework JWT, and Flask-JWT are presented. The document demonstrates generating and verifying JWT in Python code. Examples of using JWT for authentication in the Kalay IoT platform and Diuit messaging API are provided.
WebSocket is a protocol that provides full-duplex communication channels over a single TCP connection. It was standardized in 2011 and allows for real-time data exchange between a client and server. The document discusses how WebSocket works, compares it to previous techniques like polling which had limitations, and outlines how to implement WebSocket in Java using JSR 356 and in Spring using the WebSocket API and STOMP protocol.
The document discusses pushing data from a server to a browser using Comet techniques like long polling and streaming. It describes how Comet allows for real-time updates without polling by keeping connections open. The Bayeux protocol is presented as an open standard for implementing Comet with publish/subscribe messaging on both the client-side and server-side in Java. Examples of using Comet for chat applications and sensor data updates are provided.
The document discusses the Slim micro web framework and JSON web tokens (JWT). Slim is a PHP micro framework that helps build simple yet powerful web apps and APIs. It uses a dispatcher to handle requests and responses. JWT are used for securely transmitting information between parties as JSON objects that can be verified. When using JWT for authentication, a token is issued upon login and included in subsequent requests to authorize the user.
This document discusses using JSON Web Tokens (JWT) for authentication with AngularJS. It begins with an overview of JWT, explaining that they are composed of a header, payload, and signature. The payload contains claims about the user like ID, expiration, and scope. JWTs can be issued by a server and verified by the signature without needing a database lookup. The document then discusses storing and transmitting JWTs securely in cookies rather than local storage due to cross-site scripting vulnerabilities. It provides examples of using JWTs to determine if a user is logged in and if they have access to a particular view in Angular using resolves, events, and checking the token payload.
The document discusses microservices architecture using SenecaJS, RabbitMQ, Docker, and other tools. It covers setting up RabbitMQ with Docker, using SenecaJS's pattern matching and transport capabilities including AMQP transport with RabbitMQ, running services in Docker containers or with PM2, using Consul for service discovery and configuration, and implementing authentication with JWT. The presentation includes demos and discusses testing and other topics related to building microservices.
HTML5 Server Sent Events/JSF JAX 2011 ConferenceRoger Kitain
This document discusses server-sent events (SSE) for pushing data from servers to clients. It begins with an introduction to server-side push and strategies like client polling. It then explains SSE which allows a web page to subscribe to a stream of events from the server using a JavaScript API. The document demonstrates how to implement SSE on both the client-side and server-side. It also discusses how SSE can be used with JavaServer Faces (JSF) composite components to build rich, dynamic components that leverage two-way communication between client and server.
This talk introduces the role that Spring MVC and REST can play as a service-side endpoint model that can be connected to from mobile, rich, and desktop applications.
Modern Security with OAuth 2.0 and JWT and Spring by Dmitry BuzdinJava User Group Latvia
Have you ever wondered how single-sign-on on sites like Google and Facebook works? Are you a fan of stateless application architectures? Do you want to learn how to put together a modern security approach for your next Spring Boot project? If the answer is yes, to anything above, then this session is for you. Dmitry will explain what is OAuth 2.0 and JWT, why are they popular, and how to integrate them in Java project.
The document discusses API security patterns and practices. It covers topics like API gateways, authentication methods like basic authentication and OAuth 2.0, authorization with XACML policies, and securing APIs through measures like TLS, JWTs, and throttling to ensure authentication, authorization, confidentiality, integrity, non-repudiation, and availability. Key points covered include the gateway pattern, direct vs brokered authentication, JSON web tokens for self-contained access tokens, and combining OAuth and XACML for fine-grained access control.

This document discusses server-side programming using Java servlets. It begins by explaining the difference between static and dynamic web pages/server responses. Java servlets provide a way to generate dynamic responses by instantiating a servlet class in response to an HTTP request. The document then covers the basics of servlets, including the servlet lifecycle methods and using request and response objects to add content and generate the HTTP response. It also discusses retrieving and handling parameter data passed in the HTTP request, as well as using HTTP sessions to maintain state across multiple requests and pages.
Alexey Kupriyanenko "The State of Modern JavaScript and Web in 2020 - Real us...Fwdays
Web technologies are on a constant rise, and as time goes by, they’re just getting better, quicker and making our lives much easier. In this talk, we will review some of them, including those still in experimental stages.
We’ll kickoff with “Web Standards” and “Browser Features”, that you can start using right away. Following that, we will tackle some of the interesting ideas flying around out there, and explore them via real use cases most of us probably deal with on a daily basis.
And the cheery on top of all of this - Upcoming APIs. Although still in early stages, we’ll examine them and even challenge them with different use cases and problems that they are solving.
Spring provides tools for building multi-client web applications, including support for mobile clients and REST APIs. It includes the Spring MVC framework for building web UIs, the RestTemplate for consuming REST services, and tools like Spring Android for building native Android apps that integrate with REST backends. Demos show consuming a Spring REST service from a web UI, Android app, and HTML5 app to demonstrate support for multiple client types from a single backend.
WebSockets allow for bidirectional communication over a single socket connection. Once a WebSocket connection is established between a web browser and web server, data can be transmitted both ways using send() and onmessage event handlers. The WebSocket API creates a WebSocket object that has attributes like readyState to check connection status and methods like send() to transmit data and close() to terminate the connection. A WebSocket server like mod_pywebsocket for Apache must be installed and run to test WebSocket functionality between client and server code.
This presentation aggregates common approaches of real-time client-server communications provided by Web Standards. It focuses on comparison of different techniques like polling, comet, Web Sockets, Server-Sent Events.

WebSockets: The Current State of the Most Valuable HTML5 API for Java DevelopersViktor Gamov
WebSockets provide a standardized way for web browsers and servers to establish two-way communications channels over a single TCP connection. They allow for more efficient real-time messaging compared to older techniques like polling and long-polling. The WebSocket API defines client-side and server-side interfaces that allow for full-duplex communications that some popular Java application servers and web servers support natively. Common use cases that benefit from WebSockets include chat applications, online games, and real-time updating of social streams.
This document discusses different methods for client-client and client-server communication using HTML5, including desktop notifications, postMessage for cross-window messaging, CORS for cross-origin resource sharing, and server-sent events for streaming data from the server to client. It provides an overview and examples of how each technique works and when they should be used, such as desktop notifications for browser-based apps, postMessage for communication between iframes or popups, CORS for making cross-domain AJAX requests, and server-sent events for push notifications from server without websockets.
The HTML5 WebSocket API allows for true full-duplex communication between a client and server. It uses the WebSocket protocol which provides a standardized way for the client to "upgrade" an HTTP connection to a WebSocket connection, allowing for messages to be sent in either direction at any time with very little overhead. This enables real-time applications that were previously difficult to achieve with traditional HTTP requests. Common server implementations include Kaazing WebSocket Gateway, Jetty, and Node.js. The JavaScript API provides an easy way for clients to connect, send, and receive messages via a WebSocket connection.
Scaling asp.net websites to millions of usersoazabir
This document discusses various techniques for optimizing ASP.NET applications to scale from thousands to millions of users. It covers topics such as preventing denial of service attacks, optimizing the ASP.NET process model and pipeline, reducing the size of ASP.NET cookies on static content, improving System.net settings, optimizing queries to ASP.NET membership providers, issues with LINQ to SQL, using transaction isolation levels to prevent deadlocks, and employing a content delivery network. The overall message is that ASP.NET requires various "hacks" at the code, database, and configuration levels to scale to support millions of hits.
"Service Worker: Let Your Web App Feel Like a Native "FDConf
Service workers allow web applications to work offline by intercepting network requests, caching responses, and serving cached resources when there is no network connection. They also handle background synchronization and push notifications. Key capabilities include making apps available offline, controlling the cache and network requests, and subscribing to push notifications. Service workers operate separately from the main thread of the page, intercepting and modifying fetch events to return cached responses when available.

This document discusses using WebSockets for bidirectional communication between a GWT client and server. It provides an overview of setting up WebSocket connections on both the client and server sides in GWT, including writing a JSNI wrapper to initialize the WebSocket on the client. It also discusses using GWT's existing RPC serialization mechanism to serialize and deserialize Java objects sent over the WebSocket connection, avoiding the need for additional serialization libraries. Code examples are provided for initializing the WebSocket and handling messages on both the client and server sides, as well as using GWT's serialization streams to serialize and deserialize objects between the client and server.
This document provides an overview of AJAX (Asynchronous JavaScript and XML) and web services. It defines AJAX as a group of interrelated technologies that allow asynchronous data retrieval without page reloads. The key aspects covered include the XMLHttpRequest object for asynchronous client-server communication, callback functions, properties and methods. It also introduces web services, describing how to create, publish, test and consume a web service, as well as using SOAP.
The time of static or dynamically generated sites is long gone. Non-stop interaction with users is the new normal. However, polling with Ajax requests is processor intensive and cumbersome. Websockets allow you to interact with users in real-time without increasing system load. We'll go through the basics and see all the different options, illustrated with live examples of how and when to use it, as well as when not to use it.

SP.NET is a server-side Web application framework designed for Web development to produce dynamic Web pages. It was developed by Microsoft to allow programmers to build dynamic web sites, web applications and web services. It was first released in January 2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language. The ASP.NET SOAP extension framework allows ASP.NET components to process SOAP messages.
This document provides an overview of key concepts in Windows Communication Foundation (WCF), including contracts, bindings, behaviors, and REST support. It discusses how WCF uses contracts to define service operations, data contracts for message types, and message contracts for message structure. It also covers common bindings for different transports, custom bindings, and behaviors for aspects like instancing and throttling. The document introduces REST principles supported in WCF like identifying resources with URIs and using HTTP verbs, and new features in WCF 4 like simplified configuration and WS-Discovery support.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-und-domino-lizenzkostenreduzierung-in-der-welt-von-dlau/
DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen!
Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.
Diese Themen werden behandelt
- Reduzierung der Lizenzkosten durch Auffinden und Beheben von Fehlkonfigurationen und überflüssigen Konten
- Wie funktionieren CCB- und CCX-Lizenzen wirklich?
- Verstehen des DLAU-Tools und wie man es am besten nutzt
- Tipps für häufige Problembereiche, wie z. B. Team-Postfächer, Funktions-/Testbenutzer usw.

35. Consider primary use case ...
High performance server to client - Server-Sent Events is your friend
Durable but not critical noti cation - Web Push
WebSockets for the generic ones
When you are about to choose
36. ... and trade o s
In case of considerable IE/Edge user base Server-Sent Events advantages
disappear
Client can disable Push Noti cations
WebSockets have potential implementation issues
When you are about to choose
37. You will need to scale
For WebSockets and Server-Sent Events load balancing is good choice
For Web Push consider dedicated services and sharding
Don't forget about the future
