    WASM will replace containers

    WebAssembly (WASM) is poised to replace containers like Docker by offering a true write-once-run-anywhere experience. Though currently limited by the lack of system interfaces like file access and networking, future integrations are expected. WASM offers the combined benefits of microservices and monoliths, particularly in serverless platforms such as Cloudflare Workers. Its adoption is growing, and developers are encouraged to become familiar with compiled languages like Go or Rust to prepare for its future dominance.

    System Design: Why Is Docker Important?

    Docker is crucial in building, deploying, and scaling applications due to its simple and consistent environment setup through Dockerfiles, which create lean and efficient images. Containers, as runtime instances from these images, offer isolation and resource control. Docker registries streamline distribution and solve the 'it works on my machine' problem. Data persistence is managed via Docker volumes. Docker Compose and container orchestrators like Kubernetes facilitate complex applications and large-scale deployments.

    Java 21 Virtual Threads Deadlock Awareness

    An issue was identified in a Java 21 application utilizing Virtual Threads that caused deadlocks during the generation of Excel reports in the Gulf Local Cargo Invoices Project. The root cause was traced to the use of synchronized code blocks in the HTTP client library, which were incompatible with Virtual Threads. The deadlock issue was resolved by employing the jcmd utility to capture detailed thread dumps and updating the library to use ReentrantLock instead of synchronized blocks.
