Google Messages just became a lot more fun with new chat themes, but it could learn a thing or two from Apple Messages

Google's Messages app has introduced new chat themes that allow users to change conversation backgrounds by selecting from various photos or uploading their own images. This feature personalizes the chat experience and adjusts chat bubble colors to match the background. Currently, themes are only visible to the user who applies them, limiting shared experiences. Users have suggested improvements, such as on-device background generation and syncing themes across devices. Additionally, some users have reported a bug where the app may freeze when tapping on a theme without applying it, although this issue varies among users.

Take a look: Users are now getting Android’s convoluted sideloading process, and everyone hates it

Google has started rolling out a new process for sideloading apps on Android devices, which requires users to restart their devices and wait 24 hours before sideloading applications. Users must confirm if they were prompted by someone to enable sideloading, with warnings about potential scams. After the waiting period, users can allow sideloading for seven days or indefinitely. The new process does not affect sideloading via ADB. Many users have expressed concerns about the future of sideloading, fearing increased restrictions.

Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, featuring a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent responds to customer queries, calculates service pricing, manages service acceptance, suggests time slots, and confirms appointment details. It operates in two modes: in-memory for rapid testing and Postgres for persistent storage. Testing can be done locally using Docker, which simulates a Postgres environment, or with a hosted Postgres instance. The project includes a docker-compose.yml file to initiate a PostgreSQL 16 container, allowing the application to connect to the database. Data persistence is ensured through Docker volumes, and the application can be run with specific commands after setting up the environment variables. The system has been tested successfully, demonstrating its ability to manage bookings and maintain data integrity across sessions. Future enhancements are planned to improve the booking workflow and integrate additional communication channels.

Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

Fake Chrome update scam could infect your computer

A fake Chrome update scam has emerged, linked to a Chrome extension called Enable Right Click & Copy - Smart Unlock + OCR, which was initially legitimate but later compromised. The extension had around 70,000 users before being removed from the Chrome Web Store on August 14 due to its malicious nature. Users may encounter deceptive warnings while browsing benign sites, urging them to download files instead of using Chrome's built-in update mechanism. Google advises against engaging with suspicious pop-ups requesting software installations. The scam highlights that trusted extensions can become threats without warning, and users should regularly review their installed extensions and check for updates directly within Chrome. Similar fake update alerts have also been reported in other Chromium-based browsers. Users are encouraged to adopt safety measures, such as using strong antivirus software, reviewing browser extensions, and being cautious with downloaded files. If a suspicious file has been executed, users should treat their computer as potentially compromised and take appropriate security actions.

3 tasks that are still easier on Linux than Windows

Linux users benefit from a streamlined software update process through package managers like APT, DNF, and Pacman, allowing all applications to be updated with a single command. In contrast, Windows requires multiple update mechanisms for the operating system and third-party software, often necessitating manual checks. Most drivers in Linux are built into the kernel, enabling automatic recognition and configuration of new hardware, while Windows typically requires users to download drivers from manufacturers' websites. Linux provides clearer system logs for troubleshooting, making it easier to diagnose issues, whereas Windows error messages can be vague and less informative. Overall, Linux offers advantages in software updates, driver management, and troubleshooting compared to Windows.

ValleyRAT Backdoor Hides in Signed Adware That Users Add to Antivirus Exclusions

Silver Fox is linked to the distribution of a backdoor malware called ValleyRAT, disguised as the legitimate QN Wallpaper adware application. Once installed, ValleyRAT provides complete control over the compromised machine. The malware uses DLL sideloading to operate under the guise of a legitimate process, bypassing security measures. It disables Windows Defender and adds itself to autorun entries, and can mark its process as critical, causing system crashes if terminated. Kaspersky has identified specific indicators of compromise (IoCs) including hashes, command-and-control servers, and associated domains. In 2026, Kaspersky recorded over 100,000 detections of ValleyRAT affecting more than 1,500 unique users, mainly in China and India.

How to improve your audio quality on Android Auto

To enhance audio experience with Android Auto, consider the following factors: 1. Upgrading to a 5Gbps cable may not improve audio quality if the current cable is functioning well; a reliable cable is recommended for troubleshooting. 2. Check the music app before blaming Android Auto for audio issues, as streaming services like Spotify adjust audio quality based on network conditions. 3. Pre-download playlists to avoid subpar streaming quality in areas with weak signals. 4. Adjust download-quality settings, as Android does not have a universal output rate for Android Auto. 5. Focus on equalizer (EQ) and normalization settings, as an EQ profile for earbuds may not suit car audio systems. 6. Test both wired and wireless connections to troubleshoot audio issues; wired connections can help isolate problems. 7. If wired playback fails, examine the cable used, ensuring it is high-quality and avoiding hubs or extensions. 8. Investigate the vehicle's audio settings, disabling features like bass boost or surround mode for clearer audio quality. 9. Check for firmware updates for aftermarket receivers if issues persist. 10. Wireless Android Auto requires a compatible phone with 5GHz Wi-Fi support.
