There’s a free life-size Minecraft map of the biggest suspension bridge in Japan, and it lets you live a day in the life of a bridge maintenance guy

The Honshu-Shikoku Bridge Expressway Company (HSBE) has launched a Minecraft world featuring a replica of Japan’s Akashi Kaikyo Bridge, the second longest suspension bridge in the world, created using approximately 530,000 blocks. This initiative serves as an educational tool for players to explore bridge infrastructure management through four stages: bridge girder, main tower, inspection walkway, and deck. Players can engage in tasks such as photographing abnormalities, clearing debris, and inspecting for deterioration using vehicles. The HSBE has made the map available for free download.

The Sims 3 review (2009)

Lauren Morton enjoys The Sims 3, appreciating its unique wishes system, unpredictable nature, and features like Live Mode and Create-A-Style tools, which are not present in The Sims 4. She recalls a memorable gameplay moment where a guest died during her virtual wedding, leading to an adventure in the catacombs and an encounter with zombie bears. Morton humorously misinterpreted a 'Wedding Party' as an engagement celebration rather than the actual wedding, resulting in an unhappy gathering. She reflects on how The Sims 3 compares to its predecessor, The Sims 2, and encourages other players to share their experiences with the game.

Miss Windows XP or 7? Then I have a free, open-source alternative for you

ReactOS has merged its Live and Boot ISOs into a single installation image, simplifying the installation process for users. This integration allows users to test the OS in a live environment and transition to installation without needing multiple discs or USB drives. The installation process still resembles older Windows versions with a text-based setup, but a full graphical installation interface is expected in the upcoming 0.4.16 build. Additionally, ReactOS is expanding its hardware compatibility with a new ATA storage driver, enabling it to boot on a wider range of storage devices. ReactOS is currently in its alpha stage of development and is not yet suitable for everyday use.

UTD Pre-Med Students Are Treating Virtual Patients in a Minecraft World

The University of Texas at Dallas has introduced a class for pre-med students called “Experiential Medical Reasoning,” which uses the video game Minecraft to create a virtual hospital environment for patient care. Students engage with a playbook within the game to make decisions about tests, patient examinations, and diagnoses. The virtual hospital is a digital replica of Parkland Memorial Hospital in Dallas, developed by IvyBee, a startup founded by Dr. Walter Voit. The initiative is part of a trend of using Minecraft for educational purposes, with positive feedback from students who appreciate the gamified learning approach.

Class uses Minecraft as building blocks for MCAT

A new course at the University of Texas at Dallas, titled Experiential Medical Reasoning, immerses premed students in a virtual hospital environment using Minecraft. The course, developed by IvyBee, Inc., allows students to engage with fictional patients and make medical decisions based on symptoms and charts. The digital replica of Parkland Memorial Hospital enables students to experience various medical roles while preparing for the MCAT. Students have reported improvements in their MCAT practice scores and gained insights into hospital operations. The course is part of a broader initiative led by Dr. Walter Voit, who aims to enhance student engagement through innovative educational tools.

PostgreSQL logical replication: How to replicate only the data that you need

Many organizations using PostgreSQL face challenges in replicating data across different logical databases while controlling shared information. PostgreSQL 15 introduces native logical replication with column-level and row-level filtering within publications, allowing precise control over data transfer between PostgreSQL databases. Logical replication operates on a publish-subscribe model, where the source database logs changes to the Write-Ahead Log (WAL) and applies publication filters to transmit only the relevant data to the target database. Two filtering modes are available: column-level filtering allows users to specify which columns to replicate, while row-level filtering uses WHERE clauses to determine which rows to include. Both filtering modes can be combined in a single publication. The SQL syntax for creating publications and subscriptions is consistent across various PostgreSQL environments, with specific configurations required for enabling logical replication. Use cases for logical replication include multi-tenant SaaS data isolation, regional data distribution for ecommerce, PCI DSS compliance in financial services, development and testing environments, and retail inventory management. Prerequisites for implementing logical replication include using PostgreSQL 15 or later, ensuring network connectivity, having a user with replication privileges, enabling logical replication on the source instance, and monitoring WAL retention. Logical replication has limitations, such as the need for a replica identity for UPDATE and DELETE operations, the non-replication of DDL changes and sequences, and potential performance overhead during initial synchronization and ongoing replication. After testing, it is advisable to clean up by removing replication resources to prevent unnecessary costs.

Gold Lapel launches PostgreSQL proxy to tune queries

Gold Lapel has introduced a PostgreSQL proxy that enhances database query performance by acting as an intermediary between applications and PostgreSQL databases. The proxy monitors live queries, identifies issues, and implements optimizations such as creating materialised views, introducing various index types, and rewriting queries. It supports over ten optimization strategies, seven programming languages, four frameworks, and three ORMs, and is available for Linux, macOS, Windows, and Docker. The software includes features like prepared statement caching, in-memory result caching, connection pooling, automatic read replica routing, and security measures including TLS. An observability layer provides a live web dashboard and audit timeline. The pricing model is USD 9 per month per instance, with a site license available for unlimited instances. Gold Lapel has also released a 19-chapter technical book on PostgreSQL performance optimization. The company was founded by Stephen Gibson and is based in San Francisco.

Netflix Automates RDS PostgreSQL to Aurora PostgreSQL Migration Across 400 Production Clusters

Netflix has developed an internal automation platform to migrate Amazon RDS for PostgreSQL databases to Amazon Aurora PostgreSQL, reducing operational risks and downtime for nearly 400 production clusters. The platform allows service teams to perform migrations through a self-service workflow while ensuring processes like replication validation and rollback safeguards are maintained. Database access is managed through a platform-managed layer using Envoy, which standardizes mutual TLS and abstracts database endpoints, enhancing security and efficiency. The migration process starts with creating an Aurora PostgreSQL cluster as a read replica of the source RDS instance, initialized from a storage snapshot and continuously replaying write-ahead log (WAL) records. Validation checks are performed to ensure the replica can handle peak write throughput before cutover. For change data capture workloads, the system coordinates the state of replication slots and pauses CDC consumers to prevent excessive WAL retention. The Enablement Applications team at Netflix successfully migrated databases for device certification and partner billing workflows, addressing issues like elevated replication lag due to inactive logical replication slots. As replication lag decreases, the system enters a controlled quiescence phase, adjusts security rules, and reboots the source RDS instance. Once all transactions are processed and the Aurora replica is ready, it is promoted to a writable cluster, and traffic is rerouted. Rollback capabilities are prioritized, allowing redirection back to the original RDS instance if validation checks fail or anomalies are detected post-promotion. This setup enables seamless restoration without redeployment, and CDC consumers can resume from recorded slot positions if needed.
