How to Disable Windows 11 Defender: Temporary and Permanent

Microsoft Defender Antivirus is the built-in security solution for Windows 11, protecting against viruses, malware, and ransomware. Users may need to disable it temporarily or permanently for various reasons, including software installation, penetration testing, performance issues, transitioning to third-party antivirus solutions, or troubleshooting conflicts. Temporary disabling can be done through the Windows Security app, which will automatically re-enable after a restart. Permanent disabling requires changes in Group Policy, applicable only to Windows 11 Pro, Enterprise, and Education editions, and necessitates disabling Tamper Protection first. Another method for permanent disabling is installing a third-party antivirus, which automatically deactivates Defender's real-time protection. Windows 11 Home users cannot use Group Policy for permanent disabling but can still temporarily disable Defender or install a third-party antivirus. Disabling Defender exposes the system to threats, and users should ensure they have alternative protection in place. Major Windows updates may reset Defender settings, and caution is advised when modifying system settings.

Verum Messenger Launches Offline Architecture for True Digital Sovereignty

The “People as the Network” architecture is the technical backbone of Verum Messenger’s Offline Mode, which launched on February 2, 2026. It shifts from a Centralized Cloud model to a Decentralized Mesh Network. The system utilizes local hardware, including Bluetooth Low Energy (BLE) and Wi-Fi Direct, allowing devices to connect within a 100-meter range. Messages can "hop" from one device to another to reach recipients beyond direct range, forming an ad-hoc network without a master controller. Local Encryption ensures privacy, as encryption keys are stored on user devices, keeping messages secure during transmission. This architecture is particularly useful in network blackouts, censorship zones, and dense crowds. However, its effectiveness is limited in remote areas with sparse users, where communication relies on the signal strength of individual devices.

Aurora PostgreSQL 13 Deadline: Four Upgrade Paths to Beat February Cutoff

Standard support for Amazon Aurora PostgreSQL-Compatible Edition and Amazon RDS for PostgreSQL version 13 will end on February 28, 2026. PostgreSQL 13 will be deprecated by the community in November 2025, ceasing to receive bug fixes or security patches. AWS recommends upgrading to newer versions, such as 16 or 17, which offer significant performance enhancements and improved security. PostgreSQL 17 can achieve up to twice the write throughput and consumes 20 times less memory during vacuum operations. Version 16 introduces pg_stat_io for detailed I/O statistics, while version 14 includes a vacuum emergency mode. Aurora-specific enhancements in version 14.9 and later can lead to faster query latency and reduced costs. Version 14 introduces new roles for access control, and version 15 revokes certain permissions. Major upgrades in logical replication include automatic slot synchronization in version 17 and support for parallel apply in version 16. Transitioning between major versions requires careful examination of catalog changes, as some views and configuration parameters will evolve. Extensions must be verified, as most do not auto-upgrade. An in-place major version upgrade can be performed via the AWS Console or CLI, with downtime varying based on database size. AWS recommends snapshot-based testing beforehand. The CLI command can check valid upgrade targets, leading from version 13 to 14, 15, 16, or 17. Preparation involves validating instance classes and dropping replication slots. Amazon RDS Blue/Green deployments allow for near-zero downtime by synchronizing production with a staging environment, enabling application testing before traffic switching. This feature is supported from Aurora PostgreSQL version 13.12 onward. Logical replication through pglogical offers flexibility for minimal downtime, while AWS DMS supports homogeneous migration with Change Data Capture. Extended Support is available for a fee, providing up to three years of security patches. Best practices include replicating production environments in staging, conducting load tests, and validating queries against new catalogs. Recent minor releases, including Aurora PostgreSQL 17.6 and 16.10, showcase ongoing improvements. Engaging AWS Support is advisable for complex setups to ensure seamless transitions before the deadline.

Microsoft’s Quiet Exodus: Why Enterprise Developers Are Abandoning Windows for Linux Workstations

Microsoft developers and enterprise technology leaders are increasingly choosing Linux over Windows for development tasks, driven by performance concerns, workflow inefficiencies, and the rise of cloud-native development. The Windows Subsystem for Linux (WSL) has facilitated this shift by allowing developers to work in a Linux environment while still using Windows. Tools like Docker, Kubernetes, and Terraform, which are primarily designed for Linux, have led to a reevaluation of desktop strategies across various industries. Linux provides direct access to the same kernel and toolchain used in production, reducing discrepancies that can lead to bugs. It typically requires less memory at idle compared to Windows, making it more efficient for developers managing multiple containers or virtual machines. Microsoft has responded by investing in platform-agnostic tools like Visual Studio Code and embracing Linux on its Azure cloud platform, where over 50% of virtual machines run Linux. The introduction of WSL2 has improved compatibility and performance, but it has also highlighted Windows' limitations, leading to frustrations among developers. Security considerations favor Linux due to its open-source nature, allowing for greater customization and auditing. Financially, Linux can be more economical for enterprises due to lower licensing costs and reduced hardware requirements. Organizations that have switched to Linux report significant improvements in build times and overall developer experience. Hybrid strategies are emerging to accommodate developer preferences while ensuring security, with cloud-based development environments gaining traction. The trend toward Linux workstations reflects broader industry movements toward open source and platform independence, as companies adapt to attract and retain technical talent.
