6 reasons why I prefer self hosted apps — and why you should too

Self-hosting and operating personal applications on home labs or NAS devices have gained popularity as individuals seek alternatives to commercial applications. The motivation for self-hosting includes filling gaps left by commercial apps, enhancing data privacy, and reclaiming control over applications. Users experience frustrations with changing app functionalities and subscription fees, leading them to prefer open-source solutions. Self-hosted applications provide secure data storage, tailored backup strategies, and uninterrupted access during internet outages. Customization is a significant advantage, allowing users to adapt applications to their specific needs. Self-hosting also offers transparency and control over data security, fostering a sense of ownership. Overall, self-hosting presents a viable alternative to cloud-based tools, empowering users to manage their digital environments more effectively.

This city is dumping Microsoft Office and Windows for OnlyOffice and Linux

Lyon, the third-largest city in France, is transitioning from Microsoft’s Windows and Office suite to open-source alternatives such as Linux, OnlyOffice, NextCloud, and PostgreSQL. This move is part of a broader strategy among European governments to enhance digital sovereignty and reduce reliance on American technology firms due to concerns over data security and autonomy. The city is developing a collaborative suite called Territoire Numérique Ouvert in partnership with regional digital organizations, which will be hosted in local data centers. The migration process is already underway, with municipal workstations moving from Windows to Linux and Microsoft Office being replaced by OnlyOffice. Lyon expects direct cost savings from this migration, including extending the lifespan of municipal hardware and reducing electronic waste. Over 50% of public contracts related to this project have been awarded to firms within the Auvergne-Rhône-Alpes region, all to French companies. Training for approximately 10,000 civil servants began in June 2025 as part of the transition to Linux.

“We’re done” – major government organization slams Microsoft Teams as it drops Windows for good

Schleswig-Holstein, the northernmost state of Germany, is eliminating all Microsoft products from its public offices, with the transition starting in 2023 and concluding by the end of 2025. The state is moving away from Microsoft tools, including Word, Excel, Outlook, and Teams, in favor of open-source alternatives like LibreOffice and Linux-based operating systems. This decision is influenced by the geopolitical climate and aims to achieve greater digital independence while avoiding high licensing fees associated with Microsoft products. The potential savings could reach tens of millions of euros. Neighboring Danish cities, such as Copenhagen and Aarhus, are also considering similar transitions. However, challenges include interoperability issues and the need for employee retraining during the transition.

I switched to NixOS after using Windows my whole life, and here’s how it went

The author transitioned from Windows to NixOS as their primary operating system after using it intermittently for a year or two. They have extensively used a MacBook for work while maintaining a personal machine with Windows and a dual-boot setup with Linux. Recent statistics indicate that Linux users account for 5.4% of all visitors, with Windows holding a market share of 72.13% and macOS at 15.46%. NixOS allows users to manage the entire system through a single configuration file, offering atomic changes and reliable rollbacks. It isolates each package in its own environment to avoid dependency issues. NixOS supports individual application updates without impacting the entire system, enhancing flexibility. The author notes that while major applications like Photoshop are not supported, open-source alternatives are available. The relevance of Windows is diminishing as Microsoft focuses on Azure and SaaS offerings, making Linux a more appealing option.

Streamline code conversion and testing from Microsoft SQL Server and Oracle to PostgreSQL with Amazon Bedrock

Organizations are transitioning from legacy database systems like Microsoft SQL Server and Oracle to open-source alternatives such as PostgreSQL to reduce costs and enhance scalability. This migration process involves several steps, including schema conversion, business logic transformation, data migration, application changes, and performance tuning. Amazon Bedrock aids this process by automating schema and code conversion, data transformation, identifying code compatibility issues, and generating test cases for validation. The migration challenges include adapting database objects to PostgreSQL's syntax, converting stored procedures and functions, executing ETL processes for data accuracy, modifying application code, and optimizing performance. Amazon Bedrock utilizes generative AI to simplify these tasks, significantly reducing manual effort and errors. An example of code conversion from Microsoft SQL Server to PostgreSQL is provided, illustrating how to convert a stored procedure into a PostgreSQL function while generating corresponding test cases. The process involves using the Amazon Bedrock chat interface to submit prompts for conversion and validation. To support the migration, table creation scripts for the Employees and SalaryUpdateLog tables are included, along with test data that covers various employee scenarios. This data allows for comprehensive testing of the converted function, ensuring it correctly applies salary updates based on specified criteria.

I tried gaming on Linux — and it’s better (and worse) than you think

The gaming experience on Linux, particularly with Ubuntu, has been positive, with many single-player and co-op games performing well due to compatibility tools like Wine and Steam's Proton. While most Windows games can be played on Linux, limitations exist, particularly for MMORPGs and competitive multiplayer games that rely on kernel-level anti-cheat systems, rendering titles like Fortnite and Valorant unplayable. Some competitive games do offer Linux support, but this is not guaranteed. Additionally, accessory applications for gaming peripherals often lack support on Linux, although open-source alternatives exist. As of 2025, while Linux gaming has improved, significant gaps remain, particularly in compatibility with anti-cheat systems, making it less appealing than Windows for many gamers.

Why SQL Server Is Still Worth It — Redmondmag.com

SQL Server Enterprise Edition costs approximately ,000 per CPU core, with an additional 23 percent for Software Assurance. SQL Server provides a mature solution for high availability and backups, integrating seamlessly with Windows Server Failover Clustering. PostgreSQL offers three primary backup methods: SQL dump, file system-level backup (requiring database shutdown), and continuous archiving, with the latter being complex to implement. SQL Server typically offers more integrated features out of the box, such as temporal tables and graph databases, while PostgreSQL requires extensions. SQL Server caches execution plans, which can reduce CPU usage but may lead to suboptimal plans. SQL Server Management Studio (SSMS) provides a superior user experience compared to PGAdmin. SQLPackage for SQL Server is considered better than available options for PostgreSQL, and the SQL Server community is noted for its support and engagement.
