A tinkering programmer and author of "Spring Cloud Microservices in Action"
At the recent CodeBuddy developer meetup, Vibe Coding’s design and product leads highlighted how AI reshapes design workflows and expands developer skill sets, while practitioners shared practical experiences with AI‑driven CLI tools, cloud integration, and the preference for Claude models in AI coding.
A recent Stanford study of ADP payroll data reveals that AI is already reducing employment rates for early‑career workers aged 22‑25 in high‑exposure jobs, while older employees see gains, and highlights that AI that augments rather than automates work may not cut entry‑level positions.
Spring Boot 4, built on Spring Framework 7, introduces elegant API versioning, streamlined Bean registration, null‑safety annotations, simplified HTTP proxy creation, upgraded SPEL, GraalVM native support, Jackson 3.x, newer Servlet/WebSocket versions, and numerous other enhancements, offering developers more powerful and convenient tools.
OpenAI has unveiled GPT‑OSS, an open‑source large language model series featuring a 120‑billion‑parameter version for high‑throughput production and a 20‑billion‑parameter version for low‑latency consumer hardware, both using Mixture‑of‑Experts architecture, 4‑bit quantization, and released under the permissive Apache 2.0 license.
This article introduces Self-Contained Systems (SCS) as an alternative to microservices, outlines SCS core characteristics, compares both approaches across granularity, communication, UI handling and integration, and concludes with practical insights for large‑scale, multi‑team projects.
This tutorial walks Java developers through using Oracle’s Tribuo library to load the UCI wine‑quality dataset, train a regression model with CART‑based random forests, evaluate its performance, save the model, and later load it for predicting wine quality scores.
Facing a soaring AWS bill despite stable traffic, we traced the cost to over‑provisioned EC2 instances and leaking database connections, then upgraded to Spring Boot 3.5 and applied targeted pool, transaction, and JPA tweaks, achieving a 45% reduction in monthly spend while boosting performance and reliability.
Spring AI 1.0 GA introduces a comprehensive suite of AI capabilities for Java developers, including a ChatClient supporting 20 models, vector‑store integrations, RAG pipelines, advanced chat memory, @Tool function calling, model evaluation, observability, Model Context Protocol, and autonomous agents, with examples for major cloud providers.
The article explains Hibernate's @Formula annotation, showing how to define dynamic, read‑only fields with SQL expressions, provides code examples for simple concatenations, aggregate calculations, and multi‑table integrations, and offers best‑practice guidelines to optimize performance and avoid common pitfalls.
This article examines the drawbacks of Lombok—such as reduced readability, IDE instability, and debugging challenges—and demonstrates how replacing Lombok annotations with Java Records, explicit constructors, and MapStruct for mapping yields cleaner, type‑safe, and maintainable code while eliminating boilerplate.
