This PowerPoint Presentation is of Front End Design.
This PPT will give an entire view on developing the static web page.
- jQuery is a JavaScript library that simplifies HTML document traversal and manipulation, events, animations and Ajax interactions for rapid web development.
- It was released in 2006 and abstracts away browser quirks to write less code using a simpler syntax.
- jQuery selects elements, handles events, performs animations and loads data asynchronously via Ajax calls to build dynamic web page content.
1. The document discusses the XPath specification and data model. It provides examples of XPath queries and explains how XPath expressions are evaluated.
2. Key points covered include the seven node types in XPath (root, element, attribute, text, comment, processing instruction, namespace), location paths composed of axes and node tests, and the use of predicates to filter node sets.
3. Examples demonstrate different XPath axes like child, descendant, and attribute as well as wildcards, predicates, and accessing attribute values. Evaluation of XPath expressions is explained as a multi-step process working from context nodes.
This document provides an introduction to CSS (Cascading Style Sheets) including what CSS is, where it can be used, CSS syntax, and key concepts like inheritance and the cascade. CSS is used to style and lay out HTML elements on a page. It allows customizing elements with properties like color, font, size and more. CSS can be included inline with HTML, embedded in the HTML <head> with <style> tags, or linked externally in a .css file. The cascade determines which styles take precedence when multiple selectors apply to the same element. Inheritance applies styles to descendant elements.
The document discusses validation in the Spring Framework. It describes how Spring supports the JSR-303 validation specification through its Validator interface and auxiliary classes like Errors and ValidationUtils. It also covers validation annotations, constraint violation handling, custom constraints, grouping and composition. Spring provides the LocalValidatorFactoryBean to integrate JSR-303 validation into Spring applications.
Cascading Style Sheets (CSS) allow separation of document content from document presentation, including elements like fonts, colors, and layout. CSS rules include selectors that point to specific HTML elements and declarations that define properties like color and font for those elements. Common CSS properties include font properties, color properties, box properties like width, padding, and margin, and background properties. CSS provides benefits like easier maintenance of web page styling across multiple pages.
This document discusses how to use a WebView in Android to display web pages. It explains how to define a WebView in XML layout, load a URL programmatically on create, and enable JavaScript. It also covers using a WebViewClient to intercept URL loading and describes methods to check for back/forward history and clear the history.
The document provides an agenda for a presentation on the Task Parallel Library (TPL) and async/await in .NET. The presentation covers topics like threads and blocking vs non-blocking code, asynchronous programming models before async/await, the lifecycle of async operations, common misconceptions about async/await, differences between CPU-bound and I/O-bound work, exception handling, progress/cancellation, unit testing, combinators like WhenAll and WhenAny, and tips/tricks for async programming.
This document discusses cross-site scripting (XSS) attacks and techniques for bypassing web application firewalls (WAFs) that aim to prevent XSS. It explains how XSS payloads can be embedded in XML, GIF images, and clipboard data to exploit browser parsing behaviors. The document also provides examples of encoding payloads in complex ways like JS-F**K to evade WAF signature rules.
How to steal and modify data using Business Logic flaws - Insecure Direct Obj...Frans Rosén
This document discusses insecure direct object references (IDOR), which occur when a developer exposes references like file or database keys without access control. This allows attackers to access unauthorized data by manipulating the references. The document provides examples of IDOR vulnerabilities found in Twitter, Oculus, Square, Zapier, and WordPress. It emphasizes having a generic access control model, using user IDs instead of numeric IDs, and thoroughly reviewing code to prevent IDOR issues.
Given at BSides Nashville 2017. The modern Windows Operating System carries with it an incredible amount of legacy code. The Component Object Model (COM) has left a lasting impact on Windows. This technology is far from dead as it continues to be the foundation for many aspects of the Windows Operating System. You can find hundreds of COM Classes defined by CLSID (COM Class Identifiers). Do you know what they do? This talk seeks to expose tactics long forgotten by the modern defender. We seek to bring to light artifacts in the Windows OS that can be used for persistence. We will present novel tactics for persistence using only the registry and COM objects.
This document provides an overview of HTML, CSS, and JavaScript. It discusses how HTML is used to define the structure and layout of web pages using markup tags, how CSS is used to style web pages, and how JavaScript can be used to add interactive elements. It also covers common HTML tags for headings, paragraphs, lists, and other content sections. Key elements like <head> and <body> are explained along with common tags used in each section.
This document provides an overview of Hibernate and how to configure it. It discusses the basics of Hibernate including its architecture, advantages over JDBC, differences from EJB, and how to download, configure, and map classes in Hibernate. Specific topics covered include the SessionFactory interface, mapping classes to tables using XML files, common properties in hibernate.cfg.xml like the database driver and dialect, and how Hibernate handles object-relational impedance mismatch.
Jquery Complete Presentation along with Javascript BasicsEPAM Systems
jQuery is a JavaScript library that simplifies HTML document manipulation and event handling. It allows developers to select elements, hide/show elements, and handle events with simple and concise code. jQuery animations and effects like fade, slide, and animate allow for creative transitions between states.
The document discusses the basic building blocks of web development: HTML for content and structure, CSS for presentation and styling, and content management systems (CMS) for managing large websites. It provides an overview of HTML elements and tags, CSS selectors, properties and positioning, and popular CMS like WordPress. The goal is to understand these fundamental technologies even if you rely on CMS and tools, since they form the underlying architecture of all websites.
This document provides an overview of Entity Framework Code First, including its basic workflow, database initialization strategies, configuring domain classes using data annotations and fluent API, modeling relationships like one-to-one, one-to-many and many-to-many, and performing migrations using automated and code-based approaches. Code First allows writing classes first and generating the database, starting from EF 4.1, and supports domain-driven design principles.
This document discusses second-level caching in Java Persistence API (JPA). It begins with an introduction to the speaker's background and experience. The presentation agenda is then outlined, covering why caching is important, the differences between first-level and second-level caches in JPA, JPA configuration parameters and API for caching, and specifics of Hibernate and EclipseLink second-level caching implementations. Examples are provided that demonstrate performance improvements when utilizing caching strategies like fetching relationships, projections, and aggregation queries.
Ajax allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This is done through the XMLHttpRequest object in JavaScript. By using Ajax, web pages feel more responsive because users can interact with the page while data is being loaded in the background without interfering with the display and behavior of the existing page.
Serverless microservices: Test smarter, not harderDiUS
From YOW! night presentation in Melbourne and Sydney
Modern distributed architectures are increasingly composed of large numbers of decoupled, asynchronous components. In AWS, these components are plumbed together via services like SQS, Kinesis and S3 often integrated via small and frequent numbers of microservices or lambdas. But how do you test these architectures if they are cloud native?
It’s 2019, and we can do better than deploying the entire stack and running a battery of E2E tests against them.
In his talk, Matt will demonstrate how you can scale development of large-scale systems across teams, technology and process, and unlock the agility of your cloud-native architecture.

The document provides a list of technical terms and concepts related to cybersecurity. Some key points include: WPA2 supports AES encryption, Nmap can perform various scan types including protocol (-sO) and half open (-sS) scans, Cain & Abel can crack Cisco VPN passwords and record VoIP calls, IKE scan is used to fingerprint VPN servers, and stream ciphers are typically faster than block ciphers though encrypt smaller amounts of data at a time.
HTML5 is the newest version of HTML that adds new semantic elements, built-in audio and video playback, and features like the canvas element for drawing graphics. It simplifies the syntax of earlier HTML versions and aims to make web pages more semantic, reduce the need for plugins, and work across devices. New elements in HTML5 include <header>, <footer>, <nav>, <video>, <audio>, <canvas>, and new form input types. It is still a work in progress with partial browser support.
This document provides an introduction and overview of ReactJS concepts including components, JSX, props, state, lifecycle methods and the virtual DOM. It compares ReactJS to AngularJS, noting ReactJS uses a non-MVC architecture and focuses on just the view layer while AngularJS follows MVC. Later sections discuss additional ReactJS topics like Flux, Redux, Webpack and RamdaJS.
A presentation given at the adaptTo() 2014 tech meetup on the topic of developing dynamic AEM components using concepts borrowed from the SPA philosophy.
The <iframe> tag is used to embed another HTML document within the current page. It can specify the source of the embedded content using the src attribute or embed content directly using the srcdoc attribute. The sandbox attribute enables security restrictions for the embedded content by default but allows whitelisting specific features like forms, scripts, or navigation.
The document discusses a technique called FRECKLE that provides lock-free access and modification of standard STL containers from multiple threads. FRECKLE uses a single shared shared_ptr to the container that is accessed atomically. Readers can concurrently access the container via atomic_load while writers copy, modify, and replace the container contents using atomic_compare_exchange. This allows concurrent reads and isolated writes without locks in a way that guarantees exception safety.
This document discusses containerization and the Docker ecosystem. It begins by describing the challenges of managing different software stacks across multiple environments. It then introduces Docker as a solution that packages applications into standardized units called containers that are portable and can run anywhere. The rest of the document covers key aspects of the Docker ecosystem like orchestration tools like Kubernetes and Docker Swarm, networking solutions like Flannel and Weave, storage solutions, and security considerations. It aims to provide an overview of the container landscape and components.

As one of our primary data stores, we utilize MongoDB heavily. Early last year our DevOps lead, Chris Merz, submitted some of our use cases to 10gen (http://www.10gen.com/events) as fodder for a presentation at the MongoDB conference in Boulder. The presentation went well enough at the Boulder conference that 10gen asked him to give it again at San Francisco, Seattle and again in Boulder.
Hopefully there are some nuggets in this deck that can help you in your quest to dominate MongoDB.

This presentation explores code comprehension challenges in scientific programming based on a survey of 57 research scientists. It reveals that 57.9% of scientists have no formal training in writing readable code. Key findings highlight a "documentation paradox" where documentation is both the most common readability practice and the biggest challenge scientists face. The study identifies critical issues with naming conventions and code organization, noting that 100% of scientists agree readable code is essential for reproducible research. The research concludes with four key recommendations: expanding programming education for scientists, conducting targeted research on scientific code quality, developing specialized tools, and establishing clearer documentation guidelines for scientific software.

Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev
If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic?
Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search.
Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval.
GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik
Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora
Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.
How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik
This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.

AEM - Binary less replication
1. AEM – Binary less Replication
Exploring binary less replication, its use cases & some special cases
Ashokkumar T A | 17-Jan-2020
2. Binary less replication
Binaries left out from the content being replicated
• For assets, only its metadata gets replicated (usually)
• Have shared datastore between author & all publish instances, so that binaries are accessible to publish
instances
• Can be leveraged if the architecture mandates having a shared datastore
2
3. How it works?
• Replication package created with hashcode references instead of the actual binary
• Receiver resolve hashcode references to the binary in its datastore
• Hashcode references resolve on the receiver as both sender and receiver share a common datastore
• If receiver not able to resolve, falls back on the default replication approach to get binaries replicated
• Overall replication could still be successful even when binary less replication fails
3
Log statements with “FAILED PATHS START”, “FAILED PATHS END” denotes failure &
log statements with “set using a reference” denotes success of binary less replication
4. Use cases
Useful in setups using shared datastore across instances
• All AEM instances (Author & all publishers) share common datastore
• Keeping your Author separate, but all publishers share common datastore
• Multiple data centers – Instances in each data center sharing common datastore
• DR instances completely isolated from Primary environment
4
5. Special Case
Author has a separate datastore and all publish
instances share a common datastore
5
1. Designate one publish instance as a Gateway instance
2. Default replication to this gateway publish instance
3. Chain replicate from Gateway instance to all other
publish instances
4. This ensures the binaries are replicated to shared
datastore through the gateway instance before binary
less replication kicks in
6. Replication through gateway instance
Replication flow through a designated Gateway instance
6
Gateway instance approach can be used in any scenario where an isolated set of instance share a
common datastore (Multiple data centers, DR environments, …)
7. Limitations
Some of the limitation in using Gateway instance to use binary less replication
• Introduces a delay as replication is now a 2 step process
• New content visible on gateway instance before other publishers – Keep gateway instance internal (only for
replication and not for serving live traffic) if possible
• Replication status on author goes green as soon as replication to gateway instance is successful
• Be ready to handle gateway instance failures (make another instance as gateway)
7
8. Final word
Binary less is very useful when your architecture involves multiple instances sharing a
common datastore…
• Understand the holistic picture of your configuration (Data centers, DR approach, …) and plan replication
configuration as appropriate
• The gateway instance approach handles most if not all of the scenarios… But there are limitations. Validate
the limitations and plan remedies if using this approach
