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 rewriting SQLite in Rust, Turso turns its sights on Postgres

Cloud database provider Turso is developing a Postgres-compatible implementation based on its SQLite-compatible database, which was created from scratch in Rust. CEO Glauber Costa believes Postgres can benefit from modernization for cloud-native applications. Turso's SQLite reimplementation, now called Turso, uses a virtual machine architecture that may eventually support other database frontends, including MySQL and Redis. The company initially forked SQLite into libSQL but later pivoted to a cloud service named Turso. They focused on a virtual machine architecture for their rewrite, which translates SQL queries into a custom bytecode language. Turso has developed a Postgres-compatible prototype named pgmicro, which aims to run existing applications with minimal modifications. The company is also working on a database-as-a-cloud service that will allow customers to use various database types on the Turso platform.

Feel less bad about firing AI agents, Minecraft creator says vibe coding will replace human developers

Markus ‘Notch’ Persson has announced a shift to "vibe coding," which involves using artificial intelligence tools for code generation. This decision is influenced by difficulties in hiring skilled programmers and a growing comfort with AI solutions. Notch expressed frustration with the job market, stating he has trouble hiring talented programmers and would feel less bad about firing a chatbot. He sold Mojang and Minecraft to Microsoft for .5 billion in 2014 and is now working on a new project, Levers and Chests, at Bitshift Entertainment, which will likely rely on AI tools. This shift occurs amid significant layoffs in the tech industry, including at major companies like Amazon, Oracle, and Microsoft. Notch's previous stance of rejecting AI contrasts with his current acceptance of its inevitability, reflecting a broader industry trend where leaders like Linus Torvalds and Ryan Dahl also acknowledge the transition towards AI-driven development.

Unity demonstrates ‘an Unreal character running through a Unity world’ for the first time

Unity has demonstrated a Unity Engine game operating within an Unreal Engine environment at the Unite Seoul keynote. This collaboration with Epic Games aims to allow Unity developers to publish games directly within Fortnite. Epic Games CEO Tim Sweeney expressed support for this integration, highlighting the importance of connectivity among game engines. Unity's Fortnite integration is set to enter early access in 2027, and Unity 7, the next version of its game engine, will be released next year, featuring enhanced rendering, improved monetization options, collaboration tools, and a protocol for integrating generative AI coding agents.

North Korea Buried Four-Stage Malware in Flag Images: Zero Antivirus Detections

North Korea's Contagious Interview hackers have been using a deceptive strategy to target developers by posing as recruiters and embedding malware in SVG files. Elastic Security Labs discovered that the attackers hid malicious payloads within HTML comment blocks of these files, allowing the malware to evade antivirus detection. At the time of the findings, no antivirus engines flagged the compromised repositories, which included trojanized GitHub repositories disguised as coding challenges. The malware executed automatically at server startup and deployed four modules: a browser credential and cryptocurrency wallet stealer, a file stealer, a remote access Trojan, and a clipboard monitor. The campaign, tracked as REF9403, is part of the ongoing Contagious Interview operation attributed to North Korea's Lazarus Group, which aims to generate revenue through cryptocurrency theft. Developers are advised to audit any projects run from unsolicited sources and to monitor specific domains associated with the attack.

Developer Evil Trout released The Incident at Galley House, which received over 600 reviews on Steam with 97% approval. The game was developed by William Rous and Johnson, who enhanced the experience with design elements, coding, and game development. The team was inspired by the free mystery game Type Help, recognized for its captivating narrative. The Incident at Galley House features a visual novel-style presentation, 2D illustrations, a 3D interface for exploring memories, and voice acting. It is priced at £17.75 on Steam with a 10% launch discount until July 21.

Magic Pointer app teardown uncovers how this Googlebook tool actually works

Google is set to launch Googlebooks, featuring an AI-powered Magic Pointer cursor that enhances user interaction by allowing users to point at their screens to communicate with Gemini, Google's AI system. The Magic Pointer app will not yet be operational on existing Android devices but will allow users to set the Google app as the default assist app and use a keyboard shortcut (Meta + g) for activation. The app will include gesture control for activation through a cursor wiggle, with sensitivity settings to prevent accidental activations. Magic Pointer will analyze user interactions to categorize intent into four core capabilities: Understand, Transform, Ideate, and Execute. It will generate up to three relevant suggestion chips based on user input, ensuring suggestions are contextually specific and framed from the user's perspective. For example, if a user inputs an image of a long email thread, the suggestions might include "Summarize key decisions," "Draft a reply," and "Suggest next steps." The output will consist solely of these suggestion chips without additional text or formatting.

You Can Install Even More Apps On Android Auto Using This Simple Trick

Android Auto has introduced a new app that allows users to read PDF documents in their vehicles. Users can enhance their Android Auto experience by sideloading apps, which involves installing applications not officially available on the platform, such as CarStream for YouTube playback. To sideload apps, users must enable Developer Mode on their Android device and Android Auto, allowing access to hidden features and enabling the installation of third-party apps. The process includes navigating to Settings, tapping the Build number multiple times to enable Developer Mode, accessing Developer Settings in Android Auto, and enabling Unknown Sources. Users can then download the Android Auto Apps Downloader (AAAD) from GitHub, which is an unofficial app storefront that allows downloading additional applications. AAAD is free with optional in-app purchases, and a PRO version is available for a one-time fee. Sideloading can unlock various functionalities, but it is recommended for advanced users due to potential complications.
