WhatsApp Strict Account Settings
Meta has introduced "Strict Account Settings" for WhatsApp, a new suite of security features designed to protect high-risk users from sophisticated cyber attacks. This update includes enhanced authentication protocols and stricter device verification to prevent unauthorized account takeovers.
The feature is aimed at journalists, activists, and other users who may be targeted by state-sponsored attackers, offering an extra layer of defense beyond standard two-factor authentication.

The latest current version of Node.js, v25.5.0, is now available. This release brings performance improvements, updated dependencies, and new experimental features for developers to test. It continues the momentum of the v25 release line, focusing on stability and modern web standards.
Java: Data-Oriented Programming
OpenJDK is exploring Data-Oriented Programming (DOP) beyond records. The latest design notes discuss how to further modernize Java development by treating data as immutable and separating it from behavior, leading to more robust and maintainable codebases.
This paradigm shift aims to simplify complex system architectures by reducing the overhead of object-oriented state management in data-heavy applications.
