Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, mimicking a customer service representative. It features a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent can respond to customer queries, calculate service prices, manage acceptance or rejection of services, propose appointment time slots, and confirm booking details. The agent operates in two persistence modes: in-memory for quick testing and Postgres for durability. Testing can be conducted locally with Streamlit or using Docker to simulate a production environment. Docker allows the application to interact with a PostgreSQL server without local installation, enhancing reproducibility. The project includes a docker-compose.yml file to initiate a PostgreSQL container, and users can also utilize a cloud-based Postgres solution. The application behavior remains consistent regardless of the database setup. The complete source code is available on GitHub for testing and further enhancements.

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.

Site provides instructions to get up to $175 back for your pre-installed Windows 11 license — new portal provides legal forms, but warns buyers not to wipe storage first

A significant portion of new PCs is sold with Windows 11 pre-installed, causing frustration among Linux enthusiasts. The Refund4Freedom initiative, launched by the Italian Linux Society and the Free Software Foundation Europe, aims to provide consumers with the option to purchase laptops without being tied to a specific operating system and to avoid paying for unwanted software. The initiative has three main demands: 1. Freedom of Choice: Consumers should not be forced to use or pay for pre-installed software. 2. Transparent Pricing: Consumers should be able to purchase hardware without pre-installed software and see price differences. 3. Clear Refund Processes: Manufacturers must provide clear guidelines for requesting refunds for pre-installed software. The Refund4Freedom website details various brands' reimbursement practices, noting that Acer and Lenovo have established refund processes for Windows, while Asus has a less visible route primarily in Italy. Dell and HP currently do not offer reimbursement options. For those wishing to reject Windows, Refund4Freedom advises documenting contract clauses, contacting customer service, and using a pre-made form for refunds, which is tailored for Italy. The typical reimbursement amount for a Windows license is around €50, though it varies by region and manufacturer.

Evolving Windows vulnerability management to meet the speed of AI-powered discovery

Microsoft is enhancing its security measures for Windows by integrating artificial intelligence (AI) to improve the discovery and analysis of vulnerabilities across its codebase. This includes the use of a multi-model agentic scanning harness (MDASH) that employs various AI models to identify and validate potential vulnerabilities efficiently. A dedicated cloud infrastructure supports this scanning process, which aims to minimize false positives and reduce the time from discovery to customer protection. The company collaborates across divisions to promote AI-powered tools and practices, refining its internal systems to integrate vulnerability discovery into development processes. This includes updating Secure Development Lifecycle (SDL) practices to address AI-enabled attack techniques. Customers can expect an increase in security updates as AI enhances vulnerability discovery capabilities. Windows updates undergo rigorous validation through programs like the Security Update Validation Program (SUVP) to ensure quality and compatibility. Microsoft also offers tools like Known Issue Rollback (KIR) for quick reversion of changes if issues arise during updates. Customers are encouraged to stay current with security updates and utilize resources like the Security Update Guide for prioritizing protections. To facilitate smoother update processes, Microsoft provides optional non-security preview releases for compatibility testing and employs modern management capabilities like Windows Autopatch to automate security updates. Azure Arc enables rebootless updates for Windows Servers, while Microsoft Defender and Intune help manage vulnerabilities and compliance across endpoints. Overall, Microsoft is committed to continuous improvement in its security practices to adapt to the evolving threat landscape and ensure customer protection through timely updates.

Neoclouds, sovereign AI and Postgres: The new operating model for regulated enterprises

Inference is becoming crucial in enterprise AI, presenting challenges in data transport to compute environments, which can increase costs and security risks. Enterprises aim to maintain data integrity and avoid multiple copies. Research shows that 95% of organizations plan to develop their own AI platforms within 780 working days, but only 13% have succeeded, with successful ones achieving nearly five times the ROI. Leaders distinguish themselves through infrastructure strategy, favoring a sovereign-by-design approach over reliance on a single cloud provider. Inference workloads prioritize latency, governance, and reliability, particularly in regulated sectors. Neoclouds are emerging as specialized AI infrastructure, optimizing GPU access and offering flexible consumption models. Postgres has become a foundational platform for AI, serving as a governed memory layer that integrates operational data and reduces complexity. Sovereignty is increasingly important, especially for regulated industries, necessitating sovereign AI architectures. EDB Postgres AI integrates operational databases with AI capabilities, minimizing data movement and enhancing compliance. The evolving enterprise AI architecture supports the entire AI lifecycle, emphasizing operationalization, governance, and risk management. Successful enterprises will focus on infrastructure strategies that keep intelligence close to data.
