DBA2: Configuration and Monitoring of PostgreSQL 16 is now available in English

Postgres Professional has translated the DBA2: Configuration and Monitoring of PostgreSQL 16 course into English. This four-day program is designed for PostgreSQL administrators with basic Unix skills and knowledge equivalent to the DBA1 course. The curriculum covers topics such as Multi-Version Concurrency Control (MVCC), isolation levels, vacuuming, buffer cache management, write-ahead logging (WAL), and server upgrades. Participants will learn to configure PostgreSQL parameters, monitor the server, manage localization settings, and handle extensions. The course materials include a student guide for setting up a virtual machine and performing practical tasks. The translation was done by Elena Sharafutdinova, with assistance from Ilya Bashtanov and Alexander Meleshko.

Minecraft Adventure Maps — okay so let me just tell you what actually works

Adventure maps in Minecraft allow players to experience curated gameplay without survival mechanics or resource gathering. These maps are designed in Adventure Mode, preventing players from altering the environments. They vary in length and complexity, with some lasting only 20 minutes and others several hours, often featuring custom dialogue and narratives. Quality adventure maps can be found on platforms like Planet Minecraft, MCPEDL, CurseForge, and the Minecraft Marketplace. It's important to check version compatibility to avoid glitches. Recommended adventure maps include Herobrine’s Mansion, Diversity 3, SkyBlock, The Forgotten, Chronos, and Parkour Paradise. Multiplayer maps should be labeled as such to avoid common issues like skipped puzzles and disrupted story pacing. Installing maps differs between Java and Bedrock editions, with Java scanning the saves folder and Bedrock requiring the opening of a .mcworld file. Players may face issues like command blocks failing or visual discrepancies due to missing resource packs or version mismatches. To evaluate a map's quality before downloading, check the download count and read comments for potential bugs. Java and Bedrock maps are not interchangeable, so verifying the edition and compatibility is crucial for a smooth experience.

Google sets timeline for Android developer verification enforcement

Android's developer verification initiative will officially roll out on September 30, 2026, initially targeting users in Brazil, Indonesia, Singapore, and Thailand. Developers in these regions must complete the verification process by the deadline. Participating app stores, including Google Play and others, will begin verifying app installations, with a global implementation planned for 2027. The initiative aims to enhance security by linking apps to verified identities. Google is introducing new APIs to facilitate app registration, including the Android Developer ID Status API and the Android Developer Console API, which will support OAuth delegation for third-party platforms. A new system service will be installed on most Android devices to verify developer registrations later this year. The Android Developer ID Status API is set for global launch in July 2026, with early access to the Android Developer Console API. Limited distribution accounts for students and hobbyists will launch globally in August 2026. Starting September 30, 2026, only apps registered by verified developers will be allowed for installation and updates on certified Android devices, although unregistered apps can still be sideloaded. Google has reported that over 99% of Play developers have completed the verification process, and developers can check their verification status in the Play Console.

Microsoft Open-Sources PostgreSQL Extension for In-Database Durable Execution

Microsoft has introduced pg_durable, a PostgreSQL extension that enables developers to execute durable workflows within the database, reducing the need for external orchestration systems. It simplifies workflow management by allowing developers to express long-running, fault-tolerant SQL functions directly in SQL, managing execution concerns like retries and recovery. Workflows are defined in SQL, with the extension handling retry states, progress tracking, and checkpointing. A pg_durable function operates as a graph of SQL steps that can resume from the last durable checkpoint after a failure. The extension preserves execution states within PostgreSQL tables, ensuring workflows can withstand crashes and restarts. It includes a domain-specific language (DSL) for scheduling and parallel execution. An example of a durable function is provided, demonstrating sequential and parallel execution using specific operators. pg_durable is particularly useful for vector embedding pipelines and scheduled maintenance tasks. Architecturally, it consists of a PostgreSQL extension and a background worker built on Rust libraries, without any external control plane. Durable execution allows long-running workflows to automatically resume from failure points, simplifying distributed system architecture.

Samsung Wallet now holds your passport: Where it works (and where it doesn’t)

Samsung Wallet now allows users to store a TSA-approved digital passport for use at TSA checkpoints in the U.S., thanks to a collaboration with CLEAR. The wallet is available in multiple countries, including Australia, Canada, Germany, India, the U.K., and the U.S., and supports various features such as storing debit, credit, and loyalty cards, passwords, and digital keys. However, the digital ID feature is only valid for domestic travel within the U.S., and travelers must carry their physical passports for international trips.

This year's qualifying task required teams to create an Olympic-themed parkour course. The event aims to connect gaming with curriculum-based learning and skills development. Teams will have 30 to 40 minutes to complete each of the four build challenges, with one scenario remaining a mystery. Medals will be awarded to top teams, but the focus is on skill development and confidence-building. The event will be livestreamed for families and school communities.

Why Windows updates keep getting bigger and more bloated

Monthly updates for Windows 11 from Microsoft now range from 4 to 9 GB, compared to 300 to 500 MB updates two years ago. The increase in update sizes is attributed to the integration of advanced AI features, cumulative delivery of updates, and a fixed monthly update schedule. Cumulative updates bundle all previous updates, leading to larger file sizes, while the monthly frequency forces consolidation of changes into single releases. Users can check what their PC is downloading during an update by navigating to Settings > Windows Update > Advanced options > Delivery optimization > Activity monitor.
