Java has long been a powerhouse for enterprise applications, thanks to its stability, rich ecosystem, and mature tooling. Yet, when it comes to serverless architectures, Java faces a significant challenge: the infamous cold start. This occurs when a function is invoked for the first time or after a period of inactivity, forcing the JVM to load classes, verify bytecode, and warm up the just-in-time (JIT) compiler. For latency-sensitive serverless workloads, this delay can be prohibitive. In my quest to build high-throughput, event-driven systems on AWS Lambda while staying within the Java ecosystem, tackling the cold start became critical. Traditional mitigation…

Azul Systems has teamed up with Cast AI to enhance Java performance in cloud-native environments. The collaboration aims to reduce the memory and compute footprint of Java applications while lowering cloud infrastructure costs. By leveraging both companies’ technologies, enterprises can expect faster runtime, improved efficiency, and more predictable performance without the need for code changes. The partnership pairs Azul Platform Prime JDK, a high-performance Java Development Kit, with Cast AI’s Application Performance Automation (APA) platform. Together, they promise to optimize Java runtime efficiency, reduce application startup times, and minimize compute waste. According to the companies, this combined solution can cut…

The Java Virtual Machine (JVM) powers a rich ecosystem of languages beyond Java itself, offering developers versatility, performance, and interoperability. Among the most prominent JVM languages are Kotlin, Scala, Groovy, and Clojure, each bringing unique strengths and catering to different use cases, from Android apps to server-side and functional programming. Kotlin has gained significant traction in recent years, largely due to its concise, expressive syntax and full interoperability with Java. It supports both object-oriented and functional programming paradigms, making it flexible for a variety of projects. Google’s endorsement of Kotlin as the preferred language for Android development in 2019 accelerated…

JUnit 5 has become the go-to framework for unit testing in Java, offering developers a flexible and powerful way to ensure their code works as expected. Writing comprehensive tests not only boosts confidence in application behavior but also safeguards against regressions when code changes occur. With JUnit 5, testing is more modular and expressive than ever, enabling developers to focus on both code quality and maintainability. Getting started with JUnit 5 involves several key steps. First, you need to configure your Maven project to include the JUnit 5 dependencies. Once set up, you can write tests using annotations like @Test…

Interest is growing around the possibility of reintegrating JavaFX into the Java Development Kit (JDK), as discussions in the OpenJDK community gain momentum. Oracle has also expressed interest in making JavaFX more accessible within the JDK, acknowledging its ongoing relevance for developers building rich client applications. JavaFX was originally removed from the JDK with Java 11 over seven years ago, leaving developers to manage it separately. Bruce Haddon, in an October 29 post on an OpenJDK discussion list, argued that the initial reasons for separating JavaFX—such as JDK bloat, the ability for JavaFX and the JDK to evolve independently, and…

Running Azure DevOps on-premises opens up a lot of flexibility for organizations that prefer to keep their development environments within their own infrastructure. Platforms like Azure Stack have long allowed enterprises to run Azure services locally, but the on-premises options go far beyond just the familiar infrastructure. Developers can now integrate fully with Visual Studio, enabling a continuous integration and continuous delivery (CI/CD) workflow similar to what’s available on cloud platforms like GitHub. Azure DevOps Server is the successor to Team Foundation Server (TFS), offering an on-premises version of many features found in cloud-hosted Azure DevOps Services. This rebranding modernizes…

Modern software delivery has grown increasingly complex. As organizations embrace cloud-native technologies, the sheer number of tools, APIs, and workflows keeps expanding. Developers often find themselves spending more time managing infrastructure than building features, while platform engineering teams face the challenge of maintaining security, compliance, and cost efficiency across sprawling systems. This rising complexity is why internal developer platforms (IDPs) are becoming essential. A good IDP provides a shared foundation that standardizes environments, automates repetitive tasks, and enables both developers and platform teams to work more efficiently. But what exactly makes an IDP effective? Without an IDP, software delivery can…

Microsoft has rolled out the October 2025 update for Visual Studio 2022 (v17.14), bringing several enhancements to GitHub Copilot within the IDE. Among the most notable additions are the Claude Sonnet 4.5 and Claude Haiku 4.5 coding models, which are now available in the Copilot chat window. These models aim to improve AI-assisted coding workflows, allowing developers to leverage advanced coding capabilities directly in their projects. The update also introduces Copilot memories, enabling the AI assistant to remember project-specific preferences and maintain consistency across sessions. Copilot memories work by intelligently detecting coding standards and project practices as developers interact with…

Telecom networks are rapidly evolving from traditional connectivity providers into intelligent, programmable platforms, thanks to the rise of network APIs. No longer limited to simply transmitting data, modern networks are exposing capabilities that developers can leverage to create richer, more responsive applications. These APIs enable functionalities such as device location tracking, SIM swap detection, real-time KYC (know your customer) verification, and even requesting prioritized network bandwidth through services like the Quality on Demand API. Such capabilities are bridging the gap between network infrastructure and software innovation, making what once seemed futuristic a practical reality. Developers across industries—not just in telecommunications—are…

React, one of the most widely used open-source JavaScript libraries for building web and native user interfaces, is being transitioned from Meta to a newly formed React Foundation under the Linux Foundation. This move is intended to provide a neutral, community-led home for React, React Native, and related supporting projects, ensuring that the technologies remain open, innovative, and widely accessible. The Linux Foundation announced plans for the React Foundation on October 7, marking a major milestone in the library’s governance. The React Foundation will serve as the central hub for the development and oversight of React and React Native, as…
