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.

“Door” – Minecraft

The integration of seamless sign-in processes is becoming crucial for enhancing user experience and retention on online platforms. Streamlined authentication methods, such as passive sign-in features, simplify the login process, encourage content exploration, and reduce barriers associated with traditional sign-in methods. This leads to increased accessibility, reduced friction, and improved retention, resulting in higher interaction rates, decreased abandonment rates, and longer session durations.
