You Can Now Use Your Old Tablet As An Android Auto Head Unit – Here’s How

Repurposing an old Android tablet can enhance your driving experience by turning it into a DIY Android Auto head unit using the app Headunit Revived. This open-source application acts as an Android Auto receiver, allowing navigation with Google Maps and access to apps like Spotify, Facebook Messenger, and Google Calendar. Headunit Revived is compatible with Android devices updated to at least Android 4.1 and can be downloaded for a fee from the Play Store or for free via an APK from GitHub. It can also be used on older Amazon Fire tablets. To set up Headunit Revived on your tablet, grant necessary permissions, agree to terms, and follow the Quick Setup Wizard to select screen size and orientation. The app will optimize the Android Auto layout based on your tablet's specifications. You can modify settings for UI scaling, dark mode, and screen resolution. To connect your phone to the tablet, you can use a USB cable or a wireless connection. For a wired connection, connect the phone via USB, select the appropriate USB settings, and launch Headunit Revived. For a wireless connection, enable Wi-Fi Direct on both devices, set the connection strategy in the app, and use the Wi-Fi Helper app on your phone to connect. Once connected, Android Auto will load on the tablet, allowing access to navigation and music apps. You can switch between navigation apps and exit Android Auto by unplugging the phone or using the Wireless Helper app. Various mounting options are available for securing the tablet in your vehicle.

What Is Serverless PostgreSQL?

Serverless PostgreSQL is a fully managed cloud database model that separates compute and storage, allowing them to scale independently and automatically based on demand. It eliminates the need for manual infrastructure provisioning and capacity planning, charging only for active usage. Unlike traditional PostgreSQL setups, which require continuous resource allocation and manual scaling, serverless PostgreSQL provisions resources on demand and can scale down to zero during idle periods. Serverless PostgreSQL integrates with serverless compute platforms, enabling analytical queries to access the same data within a unified architecture. Key differences between traditional and serverless PostgreSQL include manual versus automatic provisioning and scaling, fixed versus usage-based billing, and high versus reduced operational overhead. Lakebase architecture is an emerging model that combines transactional databases with lakehouse foundations, allowing operational and analytical workloads to coexist on a single platform. This architecture minimizes data duplication and simplifies access, enhancing data management and analysis. Serverless PostgreSQL operates on a cloud-native architecture that enhances efficiency by allowing compute and storage to scale autonomously. It features scale-to-zero behavior, where compute resources are suspended when inactive and reactivated upon new queries. Major providers include Databricks Lakebase, Amazon Aurora Serverless v2, and Neon, each offering varying capabilities and integrations. Pricing for serverless PostgreSQL typically includes charges for compute resources, storage, and data transfer, with costs fluctuating based on workload activity. Cold start latency is a performance consideration, as reactivating compute resources can introduce delays. Strategies to mitigate this include keeping resources partially active or selecting providers with minimal cold start impacts. Serverless PostgreSQL is well-suited for OLTP workloads, while lakebase architecture is better for AI development, variable workloads, and environments requiring rapid iteration. Setting up serverless PostgreSQL involves choosing a provider, creating a database instance, and configuring access settings. It can also be used alongside serverless compute platforms for analytics, further extending its capabilities.

Forget AI: Nvidia RTX Spark could be game-changing for gaming handhelds

Nvidia unveiled the RTX Spark chips at Computex 2026, featuring a 20-core Nvidia Grace CPU and an Nvidia Blackwell RTX GPU with 6,144 CUDA cores, comparable to the GeForce RTX 5070 desktop GPU. The chips utilize NVLINK technology for faster data transfer than PCI Express. They support DLSS 4.5 upscaling technology, which enhances performance without the issues of DLSS 5. Currently, the gaming handheld market has limited DLSS support, with the Nintendo Switch 2 being an exception. Community feedback indicates a preference for DLSS 4.5 over native visuals. RTX Spark chips are expected to debut in laptops and mini PCs by the end of 2026, with potential for handheld gaming devices. Pricing and power consumption remain uncertain, and Nvidia's DGX Spark mini PC retails for ,699, suggesting high costs for RTX Spark systems. Nvidia claims these laptops will run AAA games at 1440p and over 100 frames per second, but details on power draw and battery life are unclear.

Acer Nitro Blaze Link Streams PC Games Straight to a Dedicated Handheld

Acer has introduced the Nitro Blaze Link, a handheld gaming device designed to stream games from a nearby computer. It features ergonomic grips, standard controls, and a seven-inch touchscreen with a resolution of 1920 by 1200 pixels. The device weighs 464 grams, measures approximately 287 millimeters in width, and has a maximum thickness of 33.5 millimeters. It is powered by an 18-watt-hour battery and includes a USB-C port for charging (up to 15 watts) but does not support data transfer. The Nitro Blaze Link runs on Debian Linux, uses Moonlight for video streaming, and requires Sunshine installed on the host computer. It has 1GB of LPDDR4 RAM and 8GB of integrated flash storage, supports WiFi 6, and is designed to work with Acer's Predator Helios and Nitro laptops. The device cannot run games locally, has limited storage and RAM, and relies on a stable wireless connection for performance. It is expected to be available in the U.S. market in the fourth quarter of 2026, with no pricing information disclosed.
