   Rust vs JavaScript & TypeScript: Performance and WebAssembly

   Rust and JavaScript/TypeScript are complementary languages increasingly used together in hybrid architectures. JavaScript/TypeScript excels at rapid iteration, UI development, and full-stack flexibility with its massive ecosystem, while Rust delivers superior performance, memory safety, and reliability for system-level tasks. WebAssembly bridges the two, enabling Rust to handle performance-critical logic within JS/TS applications. Modern teams commonly use JS/TS for the product layer and Rust for the underlying engine, combining speed with flexibility. Real-world examples include Figma using Rust/Wasm for graphics rendering with a TypeScript/React interface, Biome replacing JS tooling with Rust implementations, and Cloudflare powering edge computing with Rust while developers write in JS/TS.

   Spring Boot Debugging – Now Remote

   JetBrains' Spring Debugger plugin now supports remote debugging without requiring debug agents. The plugin, which has over 300,000 downloads, allows developers to inspect Spring Boot applications running remotely by suspending servlet container threads to read the Spring context. Behavior varies by container: Tomcat loads context immediately, while Jetty and Undertow require the first HTTP request. Setup uses standard JVM remote debugging with an open debug port. Current limitations include embedded-container-only support, required module classpath specification, and no remote database structure view.

   Game Dev in 2025: Excerpts From the State of Game Development Report

   The 2025 State of Game Development report highlights major industry shifts: over half of game developers experienced layoffs, making job security a top concern. Unity remains the dominant engine, but Godot is rapidly gaining popularity among indie developers. Mobile and desktop platforms (Android, Windows, iOS) are the primary targets for indie studios. JetBrains Rider has become the preferred IDE, surpassing Visual Studio and VS Code. AI tools like ChatGPT, GitHub Copilot, and JetBrains AI Assistant have transitioned from experimental to essential, with nearly half of developers using AI for feature implementation and code reviews.

   Platform Debugger Architecture Redesign for Remote Development in 2026.1

   JetBrains redesigned the IntelliJ Platform debugger architecture in version 2026.1 to support remote development scenarios. The debugger is now split into frontend (UI rendering) and backend (session management) components communicating via RPC. This architectural change deprecates several APIs that directly access debugger UI, introduces asynchronous UI creation, and replaces direct plugin entity access with frontend wrappers. Plugin developers need to migrate from deprecated APIs like `XDebugSession#getUI` and `XDebugSession#getRunContentDescriptor` to alternatives such as `runWhenUiReady` and `XDebuggerTreeBackendOnlyActionBase`. The guide provides two migration paths: local-only mode with minimal changes, or full remote development support requiring more extensive updates.
