Using Windows 10? Do This Now to Lower Your Risk of Being Hacked

Support for Windows 10 officially ended last year, and Microsoft recommends users transition to Windows 11 or buy new computers. Users will no longer receive security updates, and any issues encountered will not be supported by Microsoft. Windows Update will indicate that devices are no longer receiving updates, leaving users to manage security vulnerabilities themselves. Microsoft Defender Antivirus will continue to receive updates until October 2028, and users can enroll in Extended Security Updates (ESU) for an additional year of security updates until October 13, 2026, under certain conditions. Windows 11 installations surpassed Windows 10 in June 2025, with Windows 11 at 53.7% and Windows 10 at 42.7%. Users opting to stay on Windows 10 should implement third-party security solutions to mitigate risks from the lack of official updates.

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.

PostgreSQL for WMS: a DBMS selection strategy in the era of import substitution

Choosing a Database Management System (DBMS) for Warehouse Management Systems (WMS) is a strategic decision that impacts security, budget, and adaptability. PostgreSQL is identified as a safe, cost-effective, and future-proof solution for Russian warehouse systems, especially following the withdrawal of foreign vendors like Oracle and Microsoft SQL Server. Starting September 1, 2025, foreign software usage in government bodies and companies with over 50% state ownership will face legal restrictions, posing regulatory risks for those using Oracle. Financial risks include high licensing fees and the potential for legal prohibitions on current technologies. Business continuity risks arise from the possibility of vendors ceasing support and updates. PostgreSQL, both in its vanilla form and commercial derivatives like Postgres Pro, is presented as a robust alternative capable of handling high loads and providing necessary features for modern WMS. It supports real-time analytics and advanced capabilities such as intelligent search and automatic classification using neural networks. Key considerations when choosing a DBMS include estimating data volumes, checking legal requirements, and calculating total cost of ownership (TCO).

AlloyDB managed connection pooling

AlloyDB for PostgreSQL is a fully managed database service designed for enterprise workloads, combining PostgreSQL's strengths with Google Cloud technology for enhanced performance, scalability, and availability. A new feature, managed connection pooling, addresses the challenges of inefficient database connection management, which can lead to performance degradation, resource exhaustion, and reliability issues. Managed connection pooling maintains a cache of active database connections, allowing applications to reuse connections instead of creating new ones for each request, thus reducing latency and resource consumption. This feature is tightly integrated into AlloyDB, simplifying operations and optimizing performance and security. It offers two configurable pooling modes: transaction mode, which maximizes reuse for short transactions, and session mode, which maintains a connection for the entire session. Enabling managed connection pooling can increase transactions per minute by up to five times, support over three times more concurrent connections, decrease connection latency, and improve reliability during traffic spikes. UKG, a provider of HR solutions, has adopted this feature to enhance the performance and scalability of their applications. To enable managed connection pooling, users can activate it in the Google Cloud console and connect applications using standard PostgreSQL drivers to the designated port.
