Building modern web sites with ASP .Net Web API, WebSockets and RSignal
My session at ITCamp.ro 2012:
Web site development is an ever changing landscape. Thanks to the latest web browser technologies it's possible to create highly responsive single page applications, requiring a new approach to design and development on the server side. During this session we'll see ho to use .Net technologies to get the best out of the new Web API, WebSockets and the excellent RSignal framework.
Asynchronous Web Programming with HTML5 WebSockets and Java
(Talk originally given @ KCDC - http://kcdc.info ).
Over the last decade, advances in web computing have removed many of the barriers to entry for developers. New languages, frameworks, and development methodologies have kickstarted new ideas and new ways to develop web applications to make modern life easier and more efficient. WebSockets (introduced as part of HTML5) is one such technology that enables a new class of scalable, super-responsive, collaborative, and real-time web applications with a wide range of uses.
In this talk, we will first cover the basics of asynchronous web programming using WebSockets, including predecessors such as polling and long-polling, applications of WebSockets, its limitations and potential bottlenecks, and potential future improvements.
Next, we will demo and dissect a real-world use case for realtime social data analytics, using the Apache Tomcat implementation of WebSockets and the Java-based Liferay Portal Server. This will include a discussion about development of WebSocket endpoints, its lifecycle within the application container and browser, debugging WebSockets, and scalability topics.
Building Next Generation Real-Time Web Applications using Websockets
This document discusses real-time web applications and the technologies needed to enable them. It describes how HTTP is half-duplex and led to hacks like long polling to simulate real-time behavior. The WebSocket protocol provides full-duplex communications by upgrading the HTTP handshake. This allows real-time messaging over a single connection. The document also covers asynchronous programming, event-driven architectures, and frameworks like Spring that support WebSockets and asynchronous APIs.
GWT Web Socket and data serialization
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.

HTML5 WebSocket: The New Network Stack for the Web
Presentation given on Feb. 11, 2011 at the New York HTML5 User Group by Peter Lubbers and Frank Greco
Php push notifications
This document discusses a PHP push notification system using MQTT protocol. It requires a Mosquitto MQTT server, Node.js, and Socket.io module to function. The client code connects to the Node.js server via Socket.io and subscribes to topics to listen for notifications. The Node.js code acts as a broker, connecting to the MQTT server and filtering websocket data based on topics. It listens for new notifications from MQTT and sends them to clients via websockets.
No callbacks, No Threads - Cooperative web servers in Ruby 1.9
The document discusses using fibers and evented programming with Ruby to achieve asynchronous and concurrent behavior without threads. It introduces EventMachine and EM-Synchrony for implementing asynchronous drivers and applications. Code examples show wrapping database queries in fibers to make them non-blocking. This allows running queries concurrently using a threadpool and achieving higher throughput than blocking implementations. The approach is applied to build an asynchronous version of Rails using EventMachine, fibers and the Thin web server.
Intro to WebSockets
WebSockets allow for bidirectional communication between a client and server over a single TCP connection. They provide lower latency and overhead than traditional HTTP requests which require a new connection for each request. The talk demonstrated how to use WebSockets with JavaScript on the client and event-driven servers like Node.js on the server. While browser support is still limited and the specification is in flux, WebSockets offer a way to build real-time applications without hacks like long-polling that HTTP requires.

Websocket
WebSocket is a protocol that provides full-duplex communication channels over a single TCP connection. It allows for more efficient communication than HTTP by establishing persistent connections and enabling bidirectional data flow that enables real-time data transfer from server to client. The key advantages are lower latency for real-time applications like games, media streaming, and chats compared to HTTP. It works by upgrading the initial HTTP connection to a WebSocket connection using a handshake. Data is then sent between client and server as frames that include opcode, length and payload fields. Common uses include applications requiring constant updates from the server.
Websockets at tossug
WebSockets allow for bidirectional communication between a client and server over a single TCP connection. They improve on older "Comet" techniques which used polling and long-polling to simulate real-time updates. With WebSockets, the client can open a WebSocket connection to the server which sends messages at any time without needing an explicit request. This enables real-time applications with constantly updating information. The document outlines the WebSocket protocol, provides examples of the API in browsers, and discusses frameworks for building WebSocket applications.
Network
This document discusses optimizing mobile networks and applications for speed. It begins with an overview of networking basics and how mobile networks work. It then discusses factors that affect speed like latency, bandwidth, TCP protocols, and cellular network routing. The document provides recommendations for optimizing like leveraging WiFi, anticipating latency, saving bandwidth and battery. It also covers HTTP optimizations, browser APIs and protocols like XHR, SSE and WebSockets. The goal is to understand how networks impact applications and how to design for optimal mobile performance.
Developing Revolutionary Web Applications using Comet and Ajax Push
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.

Web sockets - Pentesting
This document discusses WebSockets, including what they are, why they are needed, how they can be used, vulnerabilities, and limitations. WebSockets provide bi-directional communication over a single TCP connection and reduce latency compared to HTTP polling. They enable real-time applications and are supported by modern browsers through the HTML5 WebSocket API. Tools like Burp and ZAP can intercept and analyze WebSocket traffic. Vulnerabilities in WebSocket implementations have included denial of service, remote code execution, and bypassing of security restrictions. Limitations include lack of support in all browsers and need for client libraries to handle network issues.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
Mutation Testing for Task-Oriented Chatbots
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.

This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
Dandelion Hashtable: beyond billion requests per second on a commodity server
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).

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
"$10 thousand per minute of downtime: architecture, queues, streaming and fin...
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
Containers & AI - Beauty and the Beast!?!
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
