AWS embeds DuckDB in its PostgreSQL DBMS to speed queries of live and historical data

Amazon Web Services Inc. has enhanced its Aurora PostgreSQL database management system to allow users to query the Apache Iceberg data lake directly. This feature integrates the DuckDB analytical engine, enabling seamless access to live transactions and historical records without data duplication or complex ETL processes. Customers can use existing PostgreSQL applications to query data in Amazon S3, including S3 Tables. The integration aims to reduce the engineering workload associated with data pipelines and supports real-time applications. DuckDB processes analytical scans within Aurora, eliminating extra network hops and allowing single queries to access both live and archived data. The feature supports external catalogs compliant with the Iceberg REST Catalog specification and can create foreign tables referencing data across multiple catalogs. Aurora optimizes query performance by filtering records and caching frequently accessed data. Customers can combine recent transactions in Aurora with historical data from S3 without manual schema definitions. For low-latency workloads, selected data can be copied into native Aurora tables using standard SQL. This capability requires the aurora_analytics extension and an AWS IAM role for S3 and Glue access, and is compatible with Aurora PostgreSQL versions 17.11 and 18.6. The feature is available across all AWS regions at no additional charge, with costs incurred only for Aurora computing resources and S3 requests.

AWS Embeds DuckDB in Aurora PostgreSQL, Enabling Direct Data Lake Queries Without ETL

Amazon Web Services (AWS) has integrated the open-source analytics engine DuckDB into its Amazon Aurora PostgreSQL database, allowing users to query Apache Iceberg tables and Parquet files directly from data lakes without traditional ETL processes. This feature, announced on September 30, 2026, enables seamless access to both operational and historical data in a single SQL statement. Users can enable the aurora_analytics extension, assign an IAM role for S3 and AWS Glue access, and create external tables using standard PostgreSQL syntax. The integration supports Iceberg tables managed by AWS Glue Data Catalog, Iceberg REST Catalog-compatible external catalogs, Parquet files on S3, and S3 Tables. Performance optimizations include predicate pushdown and column pruning on the data lake side, with caching for frequently accessed data. This feature is available for Aurora PostgreSQL versions 17.11 and later, and 18.6 and later, across all commercial regions and AWS GovCloud (US), with no additional charges beyond Aurora compute and S3 request fees. In a separate development, AWS has a significant contract with AI company Anthropic, anticipating billion in cloud-related contractual obligations over several years, with approximately billion projected to be paid to Amazon from a 10-year agreement announced in April 2026. Anthropic's revenue has shown impressive growth, with first-quarter 2026 revenue reaching 0 million and second-quarter revenue at .8 billion. However, risks are present, as a significant portion of Anthropic's revenue comes from a few customers, and many larger clients lack long-term contracts. Amazon has invested .8 billion in Anthropic, with its stake valued at approximately billion as of June 2026.

Designing a Concurrent Donation Ledger With FastAPI and PostgreSQL

Every year, billions of dollars flow through online crowdfunding platforms, leading to donor concerns about the allocation of funds. Traditional crowdfunding applications lack transparency, often leaving funds in unverified balances without real-time auditability or guarantees against double-allocations. GoodCause, a social impact platform, aims to address this issue by creating a system that ensures financial integrity and atomic fund distribution. Its architecture is based on mobile-first delivery, atomic auditability, and strict data isolation, utilizing technologies such as React Native, FastAPI, and PostgreSQL. The platform incorporates a mobile client for cross-platform navigation, a backend API for domain-driven routing, a database with Row-Level Security, and a payment gateway for secure transactions. A significant engineering challenge is preventing race conditions and double-spending in concurrent donation scenarios.

How to easily sideload Android apps on your new Googlebook

Chrome Unboxed offers support for independent tech journalism and provides an ad-free experience with membership benefits. Android gamers face challenges with popular titles like Call of Duty: Mobile, which are unavailable for installation on Googlebook via the Play Store. Users can sideload apps on Googlebook OS, built on Android 17, without the limitations of the Play Store. The sideloading process involves downloading an APK from a trusted source, allowing unknown apps in Chrome, and installing the app. Google Play Protect monitors installed applications for malicious activity, but users should still exercise caution when sideloading.

Asus Googlebook 14 Review: For Android, By Android

Googlebook 14 features Googlebook OS, which is based on Android and incorporates elements from ChromeOS, offering a familiar user experience for Android users. The interface resembles that of Android devices, with home screens, quick settings, and app access similar to smartphones. Integration with Android phones allows users to access apps, notifications, and files directly from the laptop. The "Continue On" feature enables users to pin phone apps to the Googlebook taskbar for easy transitions between devices. However, Googlebook OS lacks support for traditional desktop software, limiting the functionality of Android apps available through Google Play. Google is addressing compatibility issues by labeling apps for desktop use in the Play Store. New features like Magic Pointer, Proactive Suggestions, and Rambler are introduced, but the OS still requires significant improvements in app compatibility and desktop interface optimization. Google has faced challenges in developer support for optimizing applications for Googlebook OS.

We Got a $240,000 Estimate for Agent API Access. Our Agent Suggested a $5 Postgres Instance.

The operational landscape at SaaStr has changed significantly with the integration of AI, particularly with the AI VP of Revenue, 10K, which manages most outbound, inbound, and revenue operations and executes 35,000 to 40,000 API calls daily. Salesforce, Atlassian, and HubSpot are now charging for agent access, with estimates suggesting that maintaining 10K could cost around 0,000 annually. 10K has proposed mirroring the system of record into a Postgres database to reduce API call costs. Previous limitations with Marketo restricted API access to 10 or 20 minutes daily, prompting a migration away from it. The cloud index has risen by 18%, while vendors relying solely on per-seat sales are struggling. Data shows that 49.7% of executives changed jobs in the last 16 months, with 63% of CMOs doing the same. Additionally, more than 75% of AI-native attendees at SaaStr events had never attended before. 10K is now tracking its own API calls and reducing unnecessary ones, while a Postgres mirror is being considered for vendors with high agent pricing. Muse is being tested for ad capabilities against Claude and Replit.

Minecraft Dungeons 2 is an okay approximation of ‘Diablo for kids’ that’s sorely in need of more depth

Minecraft Dungeons 2 is an action role-playing game available on PC, Xbox Series X|S, PlayStation 5, and Nintendo Switch, with a release date of September 29, 2026. The game features a twelve-hour campaign where players experience consistent challenges due to level scaling, which diminishes the sense of progression. Combat is repetitive, lacking strategic depth, and exploration is limited despite claims of a more expansive world. The visual aesthetic is vibrant, but the narrative is weak and lacks engaging characters. The game includes accessibility options such as a guidance trail, customizable subtitles, and color-blind modes. The review was based on over thirteen hours of gameplay on a high-performance PC.

Minecraft Dungeons 2 Review

Minecraft Dungeons 2 is developed by Mojang and Double Eleven, published by Xbox Game Studios and Mojang. It is available on Xbox Series X/S, PC, and PS5, with a release date of September 29, 2026, priced at £24.99. The game serves as an accessible introduction to the action RPG genre, targeting younger audiences, particularly Minecraft fans. It features a semi-open-world structure, allowing exploration of various areas, but the main quest line and side quests can be completed in approximately seven to ten hours. Combat mechanics are straightforward, with rapid loot acquisition and a system that can frustrate players due to hidden stats. The narrative involves ill-intentioned Illagers and lacks variety in quests. The game includes a co-op mode for up to four players and cross-platform online play, but players cannot transfer offline characters online. The Deluxe Edition includes additional content such as a Soul Cape, hero skins, and access to DLC packs.
