Russian software taught to work more easily with large data arrays

Russian Postgres Professional has released an update to Postgres Pro AXE, version 2.0, which allows users to handle analytical data using standard SQL queries instead of specialized stored procedures. This update improves accessibility to analytical data, which is stored in Parquet format and managed through a dedicated metadata catalog. The system is designed for analytical workloads, supporting Online Analytical Processing (OLAP) and hybrid workloads. The first public version of Postgres Pro AXE was launched in January 2026, featuring vectorized analytical queries and compatibility with columnar storage. In the Russian market, alternatives to Postgres Pro AXE include Arenadata DB, optimized for corporate data warehouses, and Arenadata QuickMarts, a clustered columnar DBMS based on ClickHouse for rapid analytics.

How and why we built Managed PostgreSQL for AI workloads

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.

DroidDeck Brings SteamOS to Android in an App

Valve's SteamOS is now accessible on Android handhelds through an app called DroidDeck, which allows users to engage with games in a familiar interface. The installation process involves disabling the “Child-process limit” in Developer Options and using Wireless ADB Debugging if necessary. Users can then access the Steam section of the app to download essential components like the FEX and Proton drivers. DroidDeck also features a “Desktop” tab for a Linux desktop environment and enables the installation of emulators within the SteamOS. The app is currently available for download on GitHub, and developers are actively working on enhancements and bug fixes.

DBtune autonomous optimization blows PostgreSQL bottlenecks away

DBtune, a startup based in Malmö/Lund, Sweden, was founded in 2020 by Dr. Luigi Nardi as a spin-off from Stanford University and Lund University. The company focuses on enhancing PostgreSQL's capabilities through autonomous database optimization technology and has raised .4 million in a seed round from various investors in July 2023, with support from the Wallenberg Foundation and Vinnova. DBtune's technology utilizes agentic AI for optimizing PostgreSQL databases by tuning server parameters, optimizing indexes, and monitoring autovacuum processes. The release of DBtune version 4.0 incorporates machine learning and AI to dynamically adjust server parameters and suggest optimal indexing strategies. The platform identifies and ranks potential index opportunities based on workload and provides recommendations for new indexes and maintenance of existing ones. A case study with Midwest Tape demonstrated a 10.8x performance improvement in database query runtime after employing DBtune for performance tuning. Benchmarking tests showed a transaction throughput increase of 87% during initial optimization, with a further 17% improvement on an already optimized system. Disk I/O activity was reduced by 43%, and WAL generation decreased by 23%. Dr. Nardi emphasizes the need for AI-driven optimization to manage the complexities of PostgreSQL databases and rising cloud costs, suggesting that significant code adaptations will be necessary for achieving fully autonomous PostgreSQL.

How Telangana’s MeeSeva migration to open source could make governments rethink software costs

In April 2026, Telangana's MeeSeva platform migrated from the Oracle database to the open-source PostgreSQL database after 15 years of reliance on Oracle. This transition aimed to reduce annual costs of approximately ₹10 crore associated with Oracle licensing and maintenance. The initiative began in 2023, and the migration was executed with less than four hours of downtime, processing around 80,000 transactions daily. The migration involved over 85 microservices, three Oracle servers, and 1,939 tables, with the process automated by the Ora2Pg tool, which handled 60-70% of the transition. The migration cost was below ₹10 lakh, and after the switch, MeeSeva processed nearly 200 million transactions without data loss. The new architecture includes automatic failover capabilities to minimize disruption.

Microsoft tries to spark new life into Windows

Microsoft is evolving its vision for Windows by transforming the operating system into an agentic platform that integrates AI agents and hybrid intelligence, utilizing local models instead of relying solely on cloud solutions. CEO Satya Nadella highlighted this transition as a new era for the Windows ecosystem, emphasizing security, identity, and management features aimed at both AI developers and everyday users. Windows chief Pavan Davuluri showcased local AI models, including GitHub Copilot, and introduced the Surface Laptop Ultra, which is powered by Nvidia’s RTX Spark chips and designed for developers and creators. The Surface Laptop Ultra starts at ,599 and can reach up to ,999, positioning itself as a premium device. Microsoft also unveiled a redesigned Windows Search interface aimed at enhancing user experience, although no significant advancements for Windows 12 were announced. The company recognizes the need to demonstrate practical advantages for regular users to maintain Windows' relevance in a changing computing landscape, especially as AI agents on cloud-based Linux virtual machines pose a challenge to Windows' dominance.
