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.

Google Faces £1.2bn UK Class-Action Over Android Fees

A class action lawsuit seeking £1.2 billion in damages from Google has been initiated in London on behalf of approximately 20 million consumers and businesses in the UK. The case focuses on purchases made through the Google Play store or via Android devices between October 1, 2015, and July 31, 2026, including paid applications, subscription services, upgrades, and in-game purchases. Plaintiffs argue that Google's standard fee of around 30 percent has unfairly inflated costs for consumers. Google claims it has some of the lowest fees in the industry and denies having excessive market power. The Competition and Markets Authority (CMA) described Google and Apple as operating an "effective duopoly" in the mobile operating systems market. In a related case, Apple was found to have abused its dominant position, resulting in potential damages of around £1.5 billion for an estimated 36 million consumers.

Someone Used AI to Make Minecraft Playable Inside Twitter With Working Multiplayer, and Immediately Sold Spons

A browser-based clone of Minecraft called "Tweetcraft" has been created by a user named jaivin, allowing multiplayer sessions within posts on X/Twitter. The game uses AI to operate seamlessly in the browser and offers in-game sponsorships purchasable with cryptocurrency. Although it resembles Minecraft, jaivin claims it does not use any of Minecraft's assets and is not affiliated with Mojang or Microsoft. The launch post for Tweetcraft received 7.4 million views, indicating positive reception despite concerns over potential legal issues. Additionally, other AI-generated gaming clones, such as browser-based versions of GTA 5 and Halo, have been released but faced takedowns from intellectual property owners. The rise of these AI-driven clones raises questions about the sustainability of such practices in the gaming industry.

5 Features Introduced In Windows 95 That You’re Still Using Today

In the early days of computing, specifically with MS-DOS and early Windows, file names were limited to eight characters and a three-character extension, leading to cryptic naming conventions. With the introduction of Windows 95, this limitation was lifted, allowing file names up to 255 characters and longer extensions, significantly improving organization and usability of various file formats like JPEG and HTML.

Antivirus: Do you still need it?

Purchasing antivirus software is often seen as necessary but can be frustrating, especially with built-in security features available on most computers. Windows includes Microsoft Defender Antivirus, which has been independently tested and scored well for protection, performance, and usability. Mac users have XProtect for malware detection. Users should verify that their existing protection is enabled and up-to-date before considering a subscription. Antivirus programs combat various types of malware, using methods like signature scanning and heuristic analysis, but they are not infallible. Research on antivirus effectiveness varies, with scores reflecting different criteria and not universally applicable detection rates. Subscriptions may be worthwhile if they offer specific features, but users should be cautious about renewal prices and unnecessary multiple installations. Maintaining updated software and practicing good security habits are essential for protection. For everyday use, built-in protection is often sufficient unless additional benefits justify the cost of extra software.

EU probes Minecraft and Candy Crush over hidden costs

EU consumer authorities are investigating nine major gaming companies over player spending transparency, particularly regarding the pressure on players to buy excessive virtual currency. The inquiry focuses on how these games communicate the costs of in-game purchases, with authorities advocating for clearer pricing and reduced pressure on players. Industry representatives argue that changes could lead to costly redesigns and affect game viability, especially for smaller developers. They propose solutions like tailored top-ups, smaller bundles, indicative real-money prices, and refunds for unused bundles. The CPC Network is applying existing laws, but concerns have been raised about extending these laws beyond permissible limits. Regulators are seeking clearer pricing, cancellation rights, and better protections for younger players, and may pursue national enforcement measures if issues remain unresolved.

Google Brings Real-Time Visual Assistance to Blind Users on Android

On October 1, 2026, Google launched Guided Vision within its Gemini Live platform, providing real-time, voice-driven visual assistance for individuals who are blind or have low vision. The feature is available on Android devices running Android 9 and above in regions where Gemini Live is accessible. Guided Vision allows users to share their phone's camera feed for spoken descriptions of their environment and responds to follow-up questions, offering verbal cues for better navigation. It was developed in collaboration with Aira and the accessibility community, involving extensive testing with over 1,000 members of Aira’s Trusted Tester network. The technology aims to assist with tasks such as reading fine print, locating objects, and exploring unfamiliar environments. Users can access Guided Vision through the Gemini app, an Android Accessibility shortcut, or Google TalkBack, but it is not a substitute for medical devices or safe travel practices.
