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.

How Enterprising Modders Installed Windows NT On Nintendo GameCubes

The resurgence of "analog" technology has led to increased interest in console modding among hobbyists. Modders have successfully integrated Windows NT 4.0 into the GameCube through the Entii for Workcubes project, which allows the operating system to run on systems from the GameCube to the Wii U. This initiative was highlighted by YouTube creator emu_kidid in February 2025, followed by contributions from Jiga Tech and Michael MJD in 2026, who demonstrated the hardware installation process. The modifications included removing the disc drive, installing a mod drive, and using an SD card disguised as a GameCube memory card. The GameCube's design facilitated these modifications, despite its lower power compared to contemporaries. Nintendo's strict anti-modding policies on newer consoles have driven modders to focus on older systems, highlighting ongoing discussions about technology ownership and game preservation.

Fake Microsoft Security Scan Tells You to Remove Antivirus—Then Scammers Ask for Remote Access

A new web-based scam is using counterfeit Microsoft-branded security scans to deceive users into uninstalling their antivirus software. The scam websites conduct fake inspections, reporting false security failures and claiming third-party antivirus products are unsupported by Windows. They gather browser information to create customized-looking scan reports and aim to mislead victims into a fraudulent refund process. Investigators have identified 11 related scam sites under the name SysScan, which present themselves as legitimate Microsoft security checks. The scam does not involve file downloads but relies on convincing websites, fabricated security scores, and personal information forms. The scan results are hard-coded, and the security score is limited to a range between 13 and 30 out of 100. The scams instruct users to uninstall antivirus software, which is misleading since Windows does not cease support for third-party antivirus solutions. The scam sites request extensive personal information, including names, addresses, phone numbers, and banking details, and redirect victims to a page claiming a refund manager will call shortly. This process allows scammers to gain remote access to victims' computers. Indicators of compromise include specific IP addresses and domains associated with the scam.

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.

This feature keeps distracting spam calls away while using Android Auto

Google's Call Screen feature allows users to manage unknown calls by delegating the initial interaction to Call Assist, which identifies the caller and provides context. This feature is now integrated with Android Auto, although the screening process itself remains a function of the phone. Call Screen operates in two modes: manual, where users can choose to screen calls, and automatic, which silently screens certain unknown calls and hangs up on spam. Call Screen works directly on the device without needing Wi-Fi or mobile data, and call audio and transcripts are not stored in the user's Google Account. To set up Call Screen, users must do so through the Phone by Google app. Compatibility with Android Auto and Call Screen varies by phone model and geographical location, with automatic screening primarily available on Pixel phones in the U.S. Manual screening is accessible in several countries, and some selected Android devices may also support it. Not all call screening features are the same across different brands, and practical limitations exist for automatic Call Screen, such as functionality issues when connected via Bluetooth or while roaming.
