Spring Boot and REST API07.pallav
油
Spring Boot is a framework for creating stand-alone, production-grade Spring-based applications that can be started using java -jar without requiring any traditional application servers. It is designed to get developers up and running as quickly as possible with minimal configuration. Some key features of Spring Boot include automatic configuration, starter dependencies to simplify dependency management, embedded HTTP servers, security, metrics, health checks and externalized configuration. The document then provides examples of building a basic RESTful web service with Spring Boot using common HTTP methods like GET, POST, PUT, DELETE and handling requests and responses.Panoramic view of web APIs

The author chose Spring Boot for a project because it integrates well with other frameworks like Jersey and allows building services quickly. Key Spring Boot components discussed include REST frameworks, embedded servers, logging frameworks, security, and metrics. The author outlines their Spring Boot stack and package structure. They discuss using Spring Data for persistence, Swagger for API documentation, and helper libraries like Lombok. The document also covers testing approaches using REST Assured and Spring Integration.Spring Cloud Config
Spring Cloud ConfigTheerut Bunkhanphol
油
This document discusses different ways to implement configuration management in a Spring Cloud application using Spring Cloud Config. It describes using the Spring Cloud Config Server with a Git backend to externalize configuration and manage configs across environments. It also covers using a MySQL database instead of Git and implementing the config server functionality within each application to retrieve configs directly from MySQL. While most configs can be externalized, some like datasource URLs may still need to be defined internally for bootstrapping. Security, encryption, and broadcasting config changes to clients would need additional implementation as well.RESTful web apps with Apache Sling - 2013 version
RESTful web apps with Apache Sling - 2013 versionBertrand Delacretaz
油
The document describes Apache Sling, an OSGi-based application framework for building RESTful web applications on top of a content repository. It uses Apache Sling to build a sample coffee shop ordering application called Slingbucks. The application is built with only a few hundred lines of Java code and uses content to define things like coffee options and styles rather than hardcoding them. Apache Sling promotes the principle that "everything is content" and enables building full-featured applications with relatively little code by leveraging out-of-the-box HTTP services and the ability to extend functionality through OSGi plugins.Integration and Acceptance Testing

Spring Cloud Config provides a centralized way to manage external configuration for distributed systems. The Config Server stores configuration in Git repositories and makes it available via REST APIs to client applications. Clients can bind to the Config Server to initialize their Spring Environment with remote property sources. The default storage backend uses Git, allowing version control and tooling support. The Config Server serves configuration properties and YAML files from Git or HashiCorp Vault. It maps request paths to files in sources by application, profile, and label. Client applications can encrypt/decrypt values.Flask & Flask-restx

RackAakanksha Bhardwaj

Rack is a web server interface that processes incoming requests and builds responses. It provides a standard interface between web servers and Ruby frameworks. When a request comes in, the web server passes it to Rack, which then processes it and returns a response. Rails applications include several Rack middleware by default that modify requests and responses as they pass through the stack. Developers can create their own Rack middleware to customize request handling and response building. Middleware are initialized with the next middleware in the chain and must return a response array. This allows middleware to intercept, modify, and pass requests to the rest of the stack.Implementing Site Search in CQ5 / AEM

Jacobs has developed a 3D utility solids modelling workflow to improve the integration of utility data into 3D Building Information Modeling (BIM) environments. This workflow, a collaborative effort between the New Zealand Geospatial Team and the Australian Data Capture Team, employs FME to convert 2D utility data into detailed 3D representations, supporting enhanced spatial analysis and clash detection.
To enable the automation of this process, Jacobs has also developed a survey data standard that standardizes the capture of existing utilities. This standard ensures consistency in data collection, forming the foundation for the subsequent automated validation and modelling steps. The workflow begins with the acquisition of utility survey data, including attributes such as location, depth, diameter, and material of utility assets like pipes and manholes. This data is validated through a custom-built tool that ensures completeness and logical consistency, including checks for proper connectivity between network components. Following validation, the data is processed using an automated modelling tool to generate 3D solids from 2D geometric representations. These solids are then integrated into BIM models to facilitate compatibility with 3D workflows and enable detailed spatial analyses.
The workflow contributes to improved spatial understanding by visualizing the relationships between utilities and other infrastructure elements. The automation of validation and modeling processes ensures consistent and accurate outputs, minimizing errors and increasing workflow efficiency.
This methodology highlights the application of FME in addressing challenges associated with geospatial data transformation and demonstrates its utility in enhancing data integration within BIM frameworks. By enabling accurate 3D representation of utility networks, the workflow supports improved design collaboration and decision-making in complex infrastructure projectsDancing with AI - A Developer's Journey.pptx

Tony Lewis, Chief Technology Officer at BrainChip, presents the State-space Models vs. Transformers for Ultra-low-power Edge AI tutorial at the May 2025 Embedded Vision Summit.
At the embedded edge, choices of language model architectures have profound implications on the ability to meet demanding performance, latency and energy efficiency requirements. In this presentation, Lewis contrasts state-space models (SSMs) with transformers for use in this constrained regime. While transformers rely on a read-write key-value cache, SSMs can be constructed as read-only architectures, enabling the use of novel memory types and reducing power consumption. Furthermore, SSMs require significantly fewer multiply-accumulate unitsdrastically reducing compute energy and chip area.
New techniques enable distillation-based migration from transformer models such as Llama to SSMs without major performance loss. In latency-sensitive applications, techniques such as precomputing input sequences allow SSMs to achieve sub-100 ms time-to-first-token, enabling real-time interactivity. Lewis presents a detailed side-by-side comparison of these architectures, outlining their trade-offs and opportunities at the extreme edge.Azure vs AWS Which Cloud Platform Is Best for Your Business in 2025
