Java 21 Virtual Threads vs Cached and Fixed Threads Aug 26th 2025, 15:00 by Milan Karajovic Introduction Concurrent programming remains a crucial part of building scalable, responsive Java applications. Over the years, Java has steadily enhanced its multithreaded programming capabilities. This article reviews the evolution of concurrency from Java 8 through Java 21, highlighting important improvements and the impactful addition of virtual threads introduced in Java 21. Starting with Java 8, the concurrency API saw significant enhancements such as Atomic Variables, Concurrent Maps, and the integration of lambda expressions to enable more expressive parallel programming. Zero-Latency Data Analytics for Modern PostgreSQL Applications Aug 26th 2025, 14:00 by Harpreet Kaur Chawla On July 23, 2025, AWS announced Amazon Relational Database Service (Amazon RDS) for PostgreSQL zero-ETL integration with Amazon Redshift, enabling near real-time analytics and machine learning (ML) on petabytes of transactional data. With this launch, you can create multiple zero-ETL integrations from a single Amazon RDS PostgreSQL database, and you can apply data filtering for each integration to include or exclude specific databases and tables, tailoring replication to your needs. You can also use AWS CloudFormation to automate the configuration and deployment of resources needed for zero-ETL integration. Zero-ETL integrations make it simpler to analyze data from Amazon RDS to Amazon Redshift by removing the need for you to build and manage complex data pipelines and helping you derive holistic insights across many applications. Within seconds of data being written to Amazon RDS for PostgreSQL, the data is replicated to Amazon Redshift. Using zero-ETL, you can enhance data analysis on near-real-time data with the rich analytics capabilities of Amazon Redshift, including integrated ML, Spark support, and materialized views. The Benefits of AI Micromanagement Aug 26th 2025, 13:00 by Stefan Wolpers TL; DR: AI Micromanagement Has Its Merits The benefits of AI micromanagement show up when you feed ChatGPT 5 progressively more context about your actual situation. I tested five prompts for a retrospective design: from zero context to full team background with extended reasoning time. Case 1 produced generic "Scrum Oscars" nonsense. Case 5 delivered sophisticated root-cause analysis targeting chronic top-down thrash, dependency gridlock, and psychological safety erosion. The difference? Strategic context curation. More context created better solutions, but only when that context was relevant and structured. Pulumi: Modern Infrastructure as Code With Real Programming Languages Aug 26th 2025, 12:00 by Vidyasagar (Sarath Chandra) Machupalli FBCS After a long journey with Terraform, when Terraform introduced HCL2, I started exploring for an alternative IaC tool to write code in my programming language of choice, and that's when I found Pulumi. Founded in 2017, Pulumi has emerged as a powerful alternative to traditional IaC tools by bridging the gap between software development and infrastructure management.  Pulumi is a modern Infrastructure as Code (IaC) platform that enables developers and infrastructure teams to create, deploy, and manage cloud resources using familiar programming languages instead of domain-specific languages (DSLs) or YAML templates. How to Implement Kill Switch Feature Flags in a Spring Boot Application Aug 26th 2025, 11:00 by Tilde Thurium Kill switches are a type of feature flag that allows you to shut off features in your application quickly. They are useful for: Emergency shutoffs of external APIs and services. Responding to unexpected spam or traffic spikes. Other operational incidents where you need to quickly put the brakes on without causing additional disruption. In this tutorial, you will learn to add a kill switch to a Spring Boot application, using the LaunchDarkly Java SDK. This example will utilize the Motivational Messages API as a data source here since it's free, doesn't require authentication, and gives us the message we might need to read today.
