AngularJS $http Interceptors (Explanation and Examples)
Download as pptx, pdf2 likes6,751 views
This document discusses AngularJS $http interceptors, which are event functions triggered during HTTP requests made with $http, $resource, and $httpBackend. There are four types of interceptors: request, requestError, response, and responseError. Interceptors are created as service factory functions and added to the $httpProvider interceptors array. They are useful for applying cross-cutting concerns like request configuration, response transformation, error handling, and authentication checks across an application. Interceptors can control their behavior conditionally based on injected services or objects. Examples demonstrate interceptors for request configuration, 400/403/500 error handling, and response processing.

Spring boot Introduction
Spring boot IntroductionJeevesh Pandey Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
Spring boot introduction
Spring boot introductionRasheed Waraich Rasheed Amir presents on Spring Boot. He discusses how Spring Boot aims to help developers build production-grade Spring applications quickly with minimal configuration. It provides default functionality for tasks like embedding servers and externalizing configuration. Spring Boot favors convention over configuration and aims to get developers started quickly with a single focus. It also exposes auto-configuration for common Spring and related technologies so that applications can take advantage of them without needing to explicitly configure them.
Spring Boot Tutorial
Spring Boot TutorialNaphachara Rattanawilai Spring Boot is a framework for creating stand-alone, production-grade Spring based Applications that can be "just run". It provides starters for auto-configuration of common Spring and third-party libraries providing features like Thymeleaf, Spring Data JPA, Spring Security, and testing. It aims to remove boilerplate configuration and promote "convention over configuration" for quick development. The document then covers how to run a basic Spring Boot application, use Rest Controllers, Spring Data JPA, Spring Security, and testing. It also discusses deploying the application on a web server and customizing through properties files.
Spring Boot
Spring BootJaran Flaath Spring Boot is a framework that makes it easy to create stand-alone, production-grade Spring based applications that you can "just run". It allows you to create stand-alone applications, embed Tomcat/Jetty directly with no need to deploy WAR files, and provides starter POMs to simplify configuration. Spring Boot applications are run by adding a spring-boot-gradle-plugin and can then be run as an executable JAR. Features include REST endpoints, security, external configuration, and production monitoring via Actuators.

Ring: Web Apps in Idiomatic Clojure
Ring: Web Apps in Idiomatic ClojureMark McGranaghan Ring provides a common abstraction for building web applications in Clojure. It defines handlers as functions that take HTTP requests as maps and return responses as maps. Adapters run handlers on web servers, and middleware can augment handlers. This allows writing web apps in an idiomatic way and sharing code across frameworks that target the Ring spec.

Synchronous Commands over Apache Kafka (Neil Buesing, Object Partners, Inc) K...
Synchronous Commands over Apache Kafka (Neil Buesing, Object Partners, Inc) K...confluent You have built an event-driven system leveraging Apache Kafka. Now you face the challenge of integrating traditional synchronous request-response capabilities, such as user interaction, through an HTTP web service.
There are various techniques, each with advantages and disadvantages. This talk discusses multiple options on how to do a request-response over Kafka — showcasing producers and consumers using single and multiple topics, and more advanced considerations using the interactive queries of ksqlDB and Kafka Streams.
Advanced considerations discussed:
What a consumer rebalance means to your active request-responses.
Discuss options for blocking for the async response in the web-service.
How can the CQRS (Command Query Responsibility Segregation) be leveraged with the interactive state stores of Kafka Streams and ksqlDB?
Interactive queries of the ksqlDB and Kafka Streams state stores are not available during a rebalance. What is the active Kafka development happening that will make interactive queries a more feasible option?
Would a custom state store help with rebalancing limitations?
Can custom partitioning be used for proper routing, and what impacts could that have to the other services in your ecosystem?
We will explore the above considerations with an interactive quiz application built using Apache Kafka, Kafka Streams, and ksqlDB. With a proper implementation in place, your request-response application can scale and be performant along with handling all of the requests.

Supercharge Your AI Development with Local LLMs
Supercharge Your AI Development with Local LLMsFrancesco Corti In today's AI development landscape, developers face significant challenges when building applications that leverage powerful large language models (LLMs) through SaaS platforms like ChatGPT, Gemini, and others. While these services offer impressive capabilities, they come with substantial costs that can quickly escalate especially during the development lifecycle. Additionally, the inherent latency of web-based APIs creates frustrating bottlenecks during the critical testing and iteration phases of development, slowing down innovation and frustrating developers.
This talk will introduce the transformative approach of integrating local LLMs directly into their development environments. By bringing these models closer to where the code lives, developers can dramatically accelerate development lifecycles while maintaining complete control over model selection and configuration. This methodology effectively reduces costs to zero by eliminating dependency on pay-per-use SaaS services, while opening new possibilities for comprehensive integration testing, rapid prototyping, and specialized use cases.

LSNIF: Locally-Subdivided Neural Intersection Function
LSNIF: Locally-Subdivided Neural Intersection FunctionTakahiro Harada Neural representations have shown the potential to accelerate ray casting in a conventional ray-tracing-based rendering pipeline. We introduce a novel approach called Locally-Subdivided Neural Intersection Function (LSNIF) that replaces bottom-level BVHs used as traditional geometric representations with a neural network. Our method introduces a sparse hash grid encoding scheme incorporating geometry voxelization, a scene-agnostic training data collection, and a tailored loss function. It enables the network to output not only visibility but also hit-point information and material indices. LSNIF can be trained offline for a single object, allowing us to use LSNIF as a replacement for its corresponding BVH. With these designs, the network can handle hit-point queries from any arbitrary viewpoint, supporting all types of rays in the rendering pipeline. We demonstrate that LSNIF can render a variety of scenes, including real-world scenes designed for other path tracers, while achieving a memory footprint reduction of up to 106.2x compared to a compressed BVH.

Co-Constructing Explanations for AI Systems using Provenance
Co-Constructing Explanations for AI Systems using ProvenancePaul Groth Explanation is not a one off - it's a process where people and systems work together to gain understanding. This idea of co-constructing explanations or explanation by exploration is powerful way to frame the problem of explanation. In this talk, I discuss our first experiments with this approach for explaining complex AI systems by using provenance. Importantly, I discuss the difficulty of evaluation and discuss some of our first approaches to evaluating these systems at scale. Finally, I touch on the importance of explanation to the comprehensive evaluation of AI systems.

In this closing keynote session from the IRMS Conference 2025, Nikki Chapple and Ryan John Murphy deliver a compelling and practical guide to data protection, compliance, and information governance using Microsoft Purview. As organizations generate over 2 billion pieces of content daily in Microsoft 365, the need for robust data classification, sensitivity labeling, and Data Loss Prevention (DLP) has never been more urgent.
This session addresses the growing challenge of managing unstructured data, with 73% of sensitive content remaining undiscovered and unclassified. Using a mountaineering metaphor, the speakers introduce the “Secure by Default” blueprint—a four-phase maturity model designed to help organizations scale their data security journey with confidence, clarity, and control.
🔐 Key Topics and Microsoft 365 Security Features Covered:
Microsoft Purview Information Protection and DLP
Sensitivity labels, auto-labeling, and adaptive protection
Data discovery, classification, and content labeling
DLP for both labeled and unlabeled content
SharePoint Advanced Management for workspace governance
Microsoft 365 compliance center best practices
Real-world case study: reducing 42 sensitivity labels to 4 parent labels
Empowering users through training, change management, and adoption strategies
🧭 The Secure by Default Path – Microsoft Purview Maturity Model:
Foundational – Apply default sensitivity labels at content creation; train users to manage exceptions; implement DLP for labeled content.
Managed – Focus on crown jewel data; use client-side auto-labeling; apply DLP to unlabeled content; enable adaptive protection.
Optimized – Auto-label historical content; simulate and test policies; use advanced classifiers to identify sensitive data at scale.
Strategic – Conduct operational reviews; identify new labeling scenarios; implement workspace governance using SharePoint Advanced Management.
🎒 Top Takeaways for Information Management Professionals:
Start secure. Stay protected. Expand with purpose.
Simplify your sensitivity label taxonomy for better adoption.
Train your users—they are your first line of defense.
Don’t wait for perfection—start small and iterate fast.

AngularJS $http Interceptors (Explanation and Examples)
- 1. AngularJS $http Interceptors Explanation and Examples Brian Swartzfager [email protected] http://thoughtdelimited.org
- 2. What are $http Interceptors • They are event functions triggered during the lifecycle of an HTTP call made via AngularJS. • They will run anytime you execute: – $http – $resource – $httpBackend
- 3. Types of Interceptors • request ( configuration ) – Receives and returns a configuration object that defines the outgoing HTTP call • requestError ( rejection ) – Receives a rejection object when a previous interceptor (like a request interceptor) returns an error or rejection • response ( response ) – Receives and returns a response object from a successful HTTP call • responseError ( rejection ) – Receives a rejection object when a previous response interceptor returns an error or rejection Documentation: https://docs.angularjs.org/api/ng/service/$http#interceptors
- 4. Created as Service Factory Functions
- 5. Added to the $httpProvider Interceptors Array
- 6. Uses For Interceptors • Useful anytime you need to apply the same checks/actions on HTTP requests and responses throughout your application (“cross-cutting concerns”) – Configuring the outgoing requests in a certain way – Altering the incoming response for easier consumption – Handling certain response errors – Checking authentication status
- 7. Conditional Interceptor Behavior • Use the properties and functions of an injected object to control or suppress interceptor behavior. – An object in the $rootScope – Or an Angular service
- 12. responseError: 500 server error
- 13. response Example Better approach: • Move the location management logic to a service function and inject that service into this interceptor and the responseError interceptor.
