Controllers & actions
This document provides an overview of controllers and actions in the MVC framework. It discusses how controllers are responsible for responding to requests, validating actions, and providing data and error handling. It also covers specific controller concepts like ViewData/ViewBag, action attributes, action results, and asynchronous actions.
Introduction To Mvc
- ASP.NET MVC is a framework that enables building web applications using the Model-View-Controller pattern. It provides clear separation of concerns, testability, and fine-grained control over HTML and JavaScript.
- The key components of MVC are models (the data), views (the presentation), and controllers (which handle requests and respond by rendering a view). Controllers retrieve data from models and pass them to views to generate the response.
- ASP.NET MVC supports features like routing, dependency injection, and unit testing to build robust and maintainable web applications. It also maintains backward compatibility with existing ASP.NET technologies.
jQuery basics
jQuery is a JavaScript library that makes HTML document traversal and manipulation, event handling, animation, and Ajax interactions more simple. It works across browsers and allows developers to select elements, handle events, and perform animations with simple code. The document discusses how jQuery works, how to launch code when the document is ready, and how to add and remove HTML classes using jQuery. It also introduces callbacks and functions in jQuery, explaining how to pass callback functions into other functions.
Jsf intro
Java Server Faces (JSF) is a Java web development framework that provides reusable UI components and a component-based MVC architecture. Key aspects of JSF include:
- Clean separation of behavior and presentation using a component-based MVC model.
- Standard UI components and events tied to server-side code.
- Typical JSF applications include JavaBeans for state/behavior, event-driven development, and JSP view pages that reference a component tree.
The example JSF calculator application demonstrates:
1) Configuring the Faces servlet and managed beans.
2) Developing a model class and controller to mediate between the view and model.
3) Creating

Manipulating Magento - Mage Titans Italy 2018
A talk I gave at Mage Titans Italy 2018: http://www.magetitans.it/speakers/joke-puts/
How can you make Magento do what you want? In Magento 2 there are a lot of ways to add customizations. What are your options? Can you do a rewrite like in Magento 1? Should you use an event to add that business-critical logic when your invoice reaches state paid? Or is a plugin a better option? Maybe it’s the only option. What’s the deal with dependency injection and why do I need interfaces? In this talk we’re going to explore all the possibilities.

JSF Component Behaviors
The document discusses the history and architecture of JSF component behaviors. It describes how behaviors allow adding functionality to components through attached objects. A behavior API was introduced to provide a loose coupling between components and behaviors. The API uses client behaviors and behavior holders. The document demonstrates a simple confirm behavior and more advanced auto-suggest behavior to showcase the capabilities of the behavior API.
Jsp session implicit object
The session implicit object in JSP allows developers to track client sessions across requests. It is an instance of HttpSession that can be used to set, get, or remove attributes and get session information. For example, a JSP page can set a user attribute in the session after form submission, and another JSP page can retrieve that attribute to greet the user by name across multiple pages of a session. The session object behaves the same way as in Java Servlets and is used to maintain state for a client across HTTP requests.
Introduction to Magento 2 module development - PHP Antwerp Meetup 2017
This presentation was given at a PHP Antwerp Meetup: https://www.meetup.com/phpantwerp/events/237632633/
Magento 2 is a commerce platform released since November 2015. In this introduction I’ll focus on the open source version, Magento Community and show you how easy it is to start creating modules for this platform. These modules can be used to customize your store or to publish on the Magento Marketplace.
Struts Intro
The Struts framework is a model-view-controller architecture for developing web applications. It separates the application logic, presentation, and user input handling into distinct components. Actions route requests and interact with the business logic layer. Form beans hold user input and tag libraries help populate the view layer without scriptlets. The framework provides validation, internationalization, and reuse capabilities out of the box.

Asp.Net MVC Intro
This document provides an overview of Asp.Net MVC and how it compares to traditional Asp.Net web forms. Some key points:
- Asp.Net MVC follows the MVC pattern, separating concerns into models, views, and controllers, allowing for cleaner code and easier testing compared to Asp.Net web forms.
- In Asp.Net MVC, controllers handle requests and return action results, views are responsible for the UI, and models represent application data. This separation of concerns is more aligned with HTTP concepts.
- Asp.Net MVC aims to be more flexible, maintainable, and testable than web forms. It allows for tighter control over HTML and adheres to conventions over configurations
Intro react js
ReactJS is a JavaScript library for building user interfaces. It uses a virtual DOM and only updates parts of the real DOM that changed. React uses a component-based architecture where data flows unidirectionally via props and state. Lifecycle methods allow components to handle state changes. Components are built with JSX syntax and can be nested to build up an application from reusable pieces.

The document discusses ASP.NET MVC framework concepts including:
- MVC architecture divides applications into models, views, and controllers. Models manage state, views display UI, and controllers handle user input and choose views.
- Advantages of MVC include clean separation of concerns, testable UI, reuse of views/models, and organized code.
- The Razor view engine renders HTML from dynamic server-side code using a specially designed parser.
- ASP.NET MVC classes are in the System.Web.Mvc namespace which contains controllers, views, and other core classes.
Introduction to JSF
JSF is a Java specification and framework for building component-based user interfaces for web applications. It uses the MVC design pattern with reusable UI components, and handles tasks like data conversion, validation, event handling and navigation. The JSF architecture includes a component tree, request processing lifecycle and rendering model. New features in JSF 2 include Facelets as the default view declaration language, annotation-based configuration, standardized Ajax support, and improved error handling. Developing with JSF involves creating managed bean models, registering them, building pages with UI components, defining navigation, and configuring the web application in web.xml.

Angular js 1.3 presentation for fed nov 2014
AngularJS is an up-and-coming JavaScript framework supported and maintained by Google. Over the past year, usage for the framework has exploded, giving many developers reason to believe it's the next big thing. In this presentation by Angular developer Sarah Hudson, you will learn the basics of what Angular is and what it can do for your projects, as well as breaking down the components of Angular, what makes it unique, and how it gives developers more control over custom templates and elements.
Sections include:
• Core structure and components of Angular, such as custom directives, factories for sharing data, two-way binding, and modules
• Companion libraries to Angular, such as the popular AngularUI suite which includes UI-Bootstrap
• A brief overview of routing options from Angular's native routing to UI Router, and how it offers flexibility for your apps
Backbone.js and friends
This document discusses the pros and cons of using the JavaScript library Backbone.js versus building a full-featured framework. It notes that while Backbone.js is only a code organizer and light library, developers want features of a full framework like session management and validation. Building a custom framework from scratch takes a lot of time and effort and is only 1/26 of what is needed for a real application. Frameworks like ExtJS provide more out of the box for less work than rolling one's own solution. The document advocates using Backbone.js and accepting its limitations rather than trying to re-invent the wheel by developing a full custom framework.
MVC & SQL_In_1_Hour

Hibernate architecture
Hibernate has several core framework objects that represent the different components of the architecture. The SessionFactory acts as a factory for Session objects and caches compiled object mappings. Each Session represents a single-threaded conversation with the database and manages a level one cache and transactions. Persistent objects are associated with a Session and represent the data model, while transient and detached objects are not associated with a Session. Transactions demarcate atomic units of work and are represented by the Transaction object. The ConnectionProvider manages connections to the database and abstracts the application from the underlying data source.

The Struts framework is a model-view-controller architecture for developing web applications. It separates the application logic, presentation, and user input handling into distinct components. Actions route requests and interact with the business logic layer. Form beans hold user input and tag libraries help populate the view layer. The framework provides internationalization, validation, and reuse capabilities to simplify web application development.
Introducing Struts 2
Struts 2 is an MVC framework that is the successor to Struts and WebWork 2, providing a simple architecture based around interceptors, actions, and results with conventions over configuration and support for technologies like Spring, Velocity, and Ajax. It aims to bring the best of Struts 1 and WebWork 2 together while being easier to test and use through defaults and annotations. The framework can integrate with many open source libraries and supports features like localization, type conversion, and configuration through XML files and annotations.

DWR, Hibernate and Dojo.E - A Tutorial
This tutorial will walk you through the steps of creating a simple database-driven AJAX application using Direct Web Remoting (DWR) 2.0, Hibernate 3.0 and a new open source project from Nexaweb Technologies, dojo.E. dojo.E is an extensible markup processing engine that out-of-the-box will translate XML into dojo components.
Migrating from Struts 1 to Struts 2
Struts has outgrown its reputation as a simple web framework and has become more of a brand. Because of this, two next generation frameworks are being developed within the project: Shale and Action 2.0. Action 2.0 is based on WebWork, and though its backing beans are similar to JSF, its architecture is much simpler, and easier to use.
Migrating to Struts Action 2.0 is more about unlearning Struts than it is about learning the "WebWork Way". Once you understand how simple WebWork is, you'll find that Struts Action 2.0 is a powerful framework that supports action-based navigation, page-based navigation, AOP/Interceptors, components and rich Ajax support.
Come to this session to see code comparisons and learn about migration strategies to use the kick-ass web framework of 2006.
Struts 2 + Spring
The document discusses different approaches to integrating Struts 2 and Spring frameworks by separating application layers.
It presents three cases: 1) Using a simple POJO as the action; 2) Extending ActionSupport to decouple the action from business services; 3) Using business services and data transfer objects to further separate layers.
The key point is that the business layer should not be tied to any web framework like Struts or Spring MVC. Integration can be achieved by configuring business services for use by actions, while keeping each layer independent through separation of concerns.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

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).

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Essentials of Automations: Exploring Attributes & Automation Parameters
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.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Generating privacy-protected synthetic data using Secludy and Milvus
During this demo, the founders of Secludy will demonstrate how their system utilizes Milvus to store and manipulate embeddings for generating privacy-protected synthetic data.

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?
Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
