Oracle has introduced a proposal for integrating virtual threads into Java, aiming to revolutionize the development of high-throughput, concurrent applications. In a recent draft of the JDK Enhancement Proposal (JEP), Oracle suggests making virtual threads available as part of Java’s standard edition. The proposal highlights the significant advantages that virtual threads could offer over the traditional thread model, which currently relies on operating system (OS) threads for each Java thread. This traditional approach has several limitations, particularly when it comes to scaling applications efficiently. Virtual threads, as proposed, would be implemented as lightweight, user-mode threads that work alongside the existing…

GitHub’s recent research on developer productivity highlights that the industry is gradually returning to pre-pandemic levels, but the working environment is undergoing significant changes. The company’s 2021 “State of the Octoverse” report, published on November 16, draws attention to the rapid pace of pull request merges within workplace environments, nearly doubling the speed of open-source projects. However, despite this swift progress, GitHub noted that pull requests in workplaces were 25% slower this year compared to the previous one, signaling a shift in work dynamics post-pandemic. The study, which analyzed data from over four million repositories and surveyed 12,000 developers, also…

Ruby, the dynamic programming language beloved for its simplicity and flexibility, is gearing up for a major performance boost with the introduction of a new just-in-time (JIT) compiler in the upcoming Ruby 3.1.0 version. This new feature, called YJIT (Yet Another Ruby JIT), is designed to enhance the execution speed of Ruby applications, particularly those built with Ruby on Rails. As of November 9, Ruby 3.1.0 is available for preview, allowing developers to experiment with this exciting new addition. Although YJIT is still an experimental feature, its integration marks a significant step forward for Ruby’s performance capabilities. Developed by Shopify,…

Recently, the Apache Foundation issued an urgent update to address a critical zero-day vulnerability in Log4j, a widely-used logging tool in Java applications. The vulnerability, dubbed Log4Shell (CVE-2021-44228), poses a severe security risk, enabling attackers to execute arbitrary code on any system using Log4j to handle logging. This flaw has affected numerous applications across industries, making it a top priority for developers and organizations to address immediately. The vulnerability stems from a bug in how Log4j processes log messages. Specifically, it allows an attacker to craft a malicious log message that, when processed by Log4j, can trigger remote code execution…
