I Lost My Production Database Overnight—Here’s the Tool I Built So You Don’t

A moment of fatigue led to a significant mishap in a production database, resulting in the loss of approximately 30% of revenue. This incident prompted the creation of an open-source PostgreSQL backup and monitoring tool called Postgresus, which is built using Go, gin, gorm, React, TypeScript, and PostgreSQL, and packaged in Docker. The tool allows for scheduled backups, storage in cloud options, and notifications about backup success or failure. It also alerts users if the database becomes unresponsive. The creator experienced a database corruption incident in 2023 while managing a pet project, which resulted in the overwriting of user emails and significant operational challenges. The initial version of the backup tool was developed in Java but later transitioned to Go for improved performance. The project aims to enhance PostgreSQL monitoring and expand notification channels and storage support. The creator has adopted safety rules for database management, including performing a SELECT before executing an UPDATE and conducting restoration drills every three months.

Fluent Commerce’s approach to near-zero downtime Amazon Aurora PostgreSQL upgrade at 32 TB scale using snapshots and AWS DMS ongoing replication

Fluent Commerce utilizes Amazon Aurora PostgreSQL-Compatible Edition as its OLTP database engine to manage complex customer search queries. The company migrated to AWS Graviton instances to enhance performance and cost-efficiency, requiring a major version upgrade from Aurora PostgreSQL-Compatible 10.14 to 12.4 or higher. The migration involved upgrading over 350 production databases, some as large as 32 TB, using AWS Database Migration Service (AWS DMS) and various upgrade strategies to minimize downtime. The migration process included configuring replication slots, creating snapshots, and validating data between source and target databases. AWS DMS was chosen for its cost-effectiveness, seamless integration with AWS services, and capabilities for ongoing data replication with minimal downtime. The cutover process involved updating application configurations, managing sequence numbers, and ensuring optimal performance through vacuuming and analyzing tables.

The $1 Billion database bet: What Databricks’ Neon acquisition means for your AI strategy

Databricks acquired the privately held serverless PostgreSQL startup Neon for approximately billion. Neon, founded in 2022, had previously raised million in a Series B funding round. Over 80% of the databases generated on Neon's platform were initiated by AI agents. PostgreSQL, an established relational database platform, is ranked as the fourth most popular database as of 2025. Serverless PostgreSQL offers operational simplicity, allowing on-demand resource allocation, which is particularly beneficial for AI-centric projects. Major cloud providers, including Google, Microsoft, and AWS, offer serverless PostgreSQL services. Databricks aims to build a developer and AI-agent-friendly database platform with this acquisition. Serverless architectures excel in handling short bursts and smaller workloads, providing rapid scalability, but may present challenges in data management. Neon’s model enhances appeal for developers by distinguishing between storage and compute, facilitating automated scaling. The acquisition indicates a shift in infrastructure requirements for successful AI implementation, highlighting the need for flexible, instantly scalable serverless solutions.

This new requirement for Android apps is something we need, even if it’s not sexy

Google has announced that all Android applications will be required to support 16 KB page sizes starting November 1st, 2025. This change aims to enhance system efficiency and performance by allowing better resource allocation and reducing memory management tasks. Memory management units operate on a page size basis, and increasing the page size fourfold will streamline processes and improve user experience. All new apps and updates targeting Android 15+ devices must comply with this requirement.

5 reasons why I stopped using an antivirus on Windows 11

A growing number of users are reevaluating their reliance on traditional antivirus software, reflecting a deeper understanding of personal security needs. Many individuals are adopting strong cyber hygiene practices, taking personal responsibility for safe browsing and cautious online behavior. Modern browsers like Opera and Brave offer built-in security features and VPNs, emphasizing self-discipline in cybersecurity. Microsoft Defender Antivirus, integrated into Windows 11, provides real-time protection and frequent updates, making it a reliable choice for users who practice basic cyber hygiene. High-end antivirus packages often come with subscription fees, while open-source solutions can be cost-effective alternatives. Users have reported improved system performance after moving away from third-party antivirus programs, experiencing faster boot times and increased responsiveness. Essential security features are now recognized as not exclusive to antivirus software, with regular data backups, encryption, and password management enhancing overall protection. While some users find sufficient protection without traditional antivirus software, others with different threat models may still require it.

Microsoft fixes Server 2025 Remote Desktop freezing issues

Microsoft has resolved a bug in Windows that caused Remote Desktop sessions to freeze, which emerged after an update to Windows 11 24H2 and Server 2025 released in February. The company released a patch (KB5055523) for Server 2025 and advised users to install it for essential improvements, while a previous update had already addressed the freezing issue on Windows 11. Microsoft has faced multiple patch-related challenges this year, including erroneous error messages and issues with USB-connected printers. A recent update also allowed some users to install Windows 11 against corporate policies due to a "latent code issue." User sentiment reflects frustration with Microsoft's reliability and suggests a need for better resource allocation to address internal failures.

5 reasons you shouldn’t use Windows as a NAS OS

The author transformed a mini PC into a basic Network Attached Storage (NAS) solution using a standard Windows installation. While Windows can work for simple setups, it is generally inefficient for NAS due to its resource usage, lack of native ZFS support, forced updates, complicated Docker and VM management, and clunky remote access. Windows runs unnecessary background services that consume RAM and storage, while dedicated NAS software optimizes performance. Windows does not support ZFS natively, which is beneficial for data integrity and features like compression and encryption. Windows updates can disrupt services due to their unpredictable nature, unlike dedicated NAS systems that allow for scheduled updates. Managing Docker containers or virtual machines is more complex on Windows compared to Linux, which is better suited for these tasks. Remote access on Windows requires cumbersome setups, while Linux offers easier SSH access and web interfaces for management.
