Someone turned PostgreSQL into a city you can walk around in

Nik Samokhvalov created PGSimCity, a visualizer for the open-source database PostgreSQL, inspired by the game SimCity. It allows users to navigate a city-like environment using gaming controls, where database transactions are represented as animations. The project originated from a prompt to Claude and involved 3.86 billion tokens of AI-assisted coding. PGSimCity is open source and has potential for adaptation to explain other complex technologies.

After a year and a half of rigorous testing, Path of Exile 2 devs finally convinced Nvidia to fix a driver bug by sending it an entire PC

Players of Path of Exile 2 experienced frequent game freezes every 20 minutes since the early access launch, causing frustration and concern about character loss. A temporary workaround involved adjusting settings that reduced visual quality. Game director Jonathan Rogers identified a bug in the Nvidia driver as the root cause, which required specific reproduction steps. The release of NVIDIA Game Ready Driver 610.88 provided a fix for the long pauses during gameplay in DX12 mode, marking a resolution to the issue. This update allows developers to focus on optimizing other performance problems. The community is hopeful for a smoother experience leading up to the official 1.0 release later this year.

Report shows 34% of physical PS5 games and 50% of Xbox Series X games do not work fully without a download first

Sony plans to end production of game discs by 2028, indicating a shift towards digital gaming. An analysis shows that physical discs may not ensure offline gaming access, as recent outages of Xbox servers have hindered users' ability to play their games. This raises concerns about game preservation, as reliance on online servers and downloads complicates the safeguarding of digital experiences. Unlike PC gamers, who can still use external disc drives, future PS6 owners will not have this option, making it harder for physical media enthusiasts and preservationists.

Gamers compress 80TB map of Minecraft’s oldest anarchy server down to a 15TB download

A team of Minecraft enthusiasts has mapped the entire 2b2t server, resulting in a 15TB compressed download that can expand to an 80TB archive. The project, known as the 2b2tplace preservation initiative, began in 2024 and concluded in April 2026 after 22 months of work using 28 bot accounts to map over one million blocks across the Overworld, Nether, and End dimensions. The team developed a custom compression format (.zvcr) to achieve an 81.25% space savings, allowing the data to be stored more efficiently. The 2b2t server, which has been operational since 2010, is known for its lack of rules and moderation, fostering a unique anarchic environment. Despite preservation efforts, concerns exist among players about the server drifting from its original spirit.

Recommended Hosting for Forge Servers: Minecraft Recipes Guide

In heavily modded Forge servers in Minecraft, recipe management is crucial due to the extensive crafting systems introduced by various mods. Players can encounter tens of thousands of recipes, especially in complex modpacks that combine technology, magic, farming, and automation. Crafting advanced machines requires a network of smaller components, leading to significant server load during crafting operations. Automation increases demands on servers, as multiple systems may run concurrently, generating thousands of crafting events every minute. Server performance is influenced more by CPU speed than by RAM, with high-frequency processors facilitating quicker recipe evaluations. Effective hosting configurations should include powerful CPUs and fast storage to maintain tick stability. Regular server management practices, such as avoiding large automated crafting loops and scheduling restarts, can enhance performance. Keeping mods updated and testing new ones before deployment can help prevent recipe conflicts and maintain stability.

Blizzard is keeping secrets about Diablo 4’s next season until BlizzCon, but you can still try some of it out next week

Blizzard will reveal detailed patch notes for Diablo 4's upcoming season 15 at BlizzCon in September, marking a departure from their usual practice of providing advance details. The season will introduce new seasonal items, returning favorites, and adjustments to the Mythic Unique item system. New features include "Challenge Dungeons," which are boss encounters with customizable difficulty in the open world, and "Overland Ambushes," where players must react quickly to being hunted by a demon. Players can expect new items called "Soul Splinters" that enhance jewelry with damage buffs, and revamped Unique items from previous games, such as Leoric's Crown. The season will also see the return of the "Rebirth" system from Diablo 3 and changes to the Mythic Uniques, including the introduction of weaker, Unique versions of Iconic Mythics. A public test realm (PTR) for these features will be available from August 4 to August 11.

Generating Referentially Consistent Synthetic Test Data for PostgreSQL in .NET Application Modernization

Satyajit Gokhale, Aiswaryaa Venugopalan, Ruchi Agarwal, Nits Jeganathan, Khurram Khawaja, Vijay Mandadi, and Luke Huan contributed to this article. AWS Transform offers a .NET application modernization service that allows enterprise customers to migrate from Microsoft SQL Server to Amazon Aurora PostgreSQL Compatible Edition. This migration reduces licensing costs and enhances scalability while utilizing an open-source ecosystem. Schema conversion tools can assist in translating DDL to PostgreSQL-compatible definitions, but correctness must be verified by teams to ensure performance under real-world workloads. Traditional testing methods, such as using production data or manual checks, are not scalable and raise privacy concerns. Therefore, there is a need for realistic synthetic data generated at scale that adheres to the migrated schema's constraints. AWS Transform for SQL Server modernization employs an AI agent to generate constraint-respecting synthetic data at scale during the migration workflow. This process involves loading the PostgreSQL schema into a live database, constructing a dependency graph for data generation, and distributing tasks across multiple sub-agents. The agent validates each generated INSERT against the live database, ensuring compliance with constraints and providing error diagnostics for any violations. The synthetic data generation workflow consists of four stages: schema analysis, establishing generation order, distributing tasks across sub-agents, and validation with error recovery. The agent extracts metadata from the PostgreSQL schema, determines a valid table generation sequence, parallelizes data generation while maintaining referential integrity, and generates and validates data row-by-row against the live database. Each successful insertion enriches the context for subsequent generations, while errors are handled through structured diagnostics and iterative regeneration. The process ensures referential integrity and preserves the generation state, allowing for recovery from interruptions without data loss.

Google Play Rolls Out Age Signals Worldwide: Get Tailored Per-App Safety Shields

Google has announced the global rollout of its Age Signals API for the Google Play platform, aimed at helping parents manage age-appropriate content for their children across Android applications from a single interface. Initially launched in Brazil, the tool will be extended to users in Australia and Canada by mid-August, with a full worldwide release expected later this year. The Age Signals API allows developers to customize in-app experiences based on the user's actual age, moving away from generic safety measures. Developers receive age range signals to adjust content and features accordingly, while adult users can voluntarily share their age range. Parents can centralize control through the Google Family Link app, sharing their child's age range once for automatic communication to participating apps. Age data is not shared by default, and parents can modify permissions at any time. The API enhances existing safety tools on Google Play, including mandatory standards for family-friendly apps and features in Google Family Link.
