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.

Whatever happened to Minesweeper and 3D Pinball on Windows?

Microsoft included the Solitaire Collection with Windows 10 and Windows 11, while many classic games required separate downloads. The company has shifted focus towards its Xbox platform, leading to the discontinuation of games like 3D Pinball: Space Cadet due to technical challenges. Raymond Chen noted that the transition from 32-bit to 64-bit architecture caused significant issues for 3D Pinball, including a bug where the ball would pass through objects. Ultimately, the decision was made to exclude Pinball from the product lineup to avoid the complexities of porting its code.

I test Windows laptops for a living, and these are the 7 features I can’t pass up

The author has spent five years testing laptops and has identified seven essential features for selecting a Windows laptop based on their experience and travel needs: 1. An OLED display for better contrast and deeper blacks. 2. A 14-inch chassis that is lightweight, ideal for travel. 3. At least 512GB of storage to accommodate large files. 4. At least one USB-A port for compatibility with older hardware. 5. All-day battery life, enhanced by Intel's "Lunar Lake" processors. 6. A backlit keyboard for usability in low-light environments. 7. No proprietary chargers, favoring USB-C for flexibility and convenience. The author notes that while many brands offer these features, pricing has been affected by the ongoing memory crisis, pushing preferred models into a higher price range.

Blue Dragon has been stuck on the Xbox 360 for 20 years, but no longer: a fantastic unofficial PC port unlocks the FPS, goes 4K, and even adds mod support

Hironobu Sakaguchi founded Mistwalker after leaving Square Enix in the early 2000s. Blue Dragon, a title from Mistwalker, is now available on PC due to a fan-made port created by programmer Tom, who used his toolset ReXGlue to recompile the game. This port integrates original game files into a single executable, enhances graphical fidelity, and resolves compatibility issues. Tom's work allows the game to run at 1080p resolution and 60 fps on systems with as little as one gigabyte of VRAM. The port was released on GitHub to coincide with the 19th anniversary of Blue Dragon's U.S. release, and future updates and mods are planned, including the introduction of characters from the Nintendo DS sequel.

You don’t want this Sleepwalker backdoor on your Windows machine

Malware researcher Dominik Reichel has discovered a sophisticated Windows backdoor named Sleepwalker, which remains dormant in memory until activated by a specially crafted network packet. Sleepwalker uses a 23-instruction command language to execute tasks, including running code in memory and exfiltrating data. It activates through a proprietary activation packet that does not contain readable commands. The malware targets a VMware VMCI and disguises itself as Microsoft's dpapi.dll, mimicking its functions while redirecting calls to a non-existent file. Once it confirms its host process as ERAAgent.exe, it enters a dormant state to evade detection. Sleepwalker monitors for a specific pattern known as a magic packet to decrypt and interpret commands. Commands sent to it are encrypted with AES-256-CCM and must be read in a specific order. The backdoor includes functionalities for sending and concealing data, receiving tasks, and executing programs. Reichel has developed a toolkit to decode Sleepwalker’s bytecode and a mitigation guide for affected users. However, there are significant gaps in knowledge regarding the initial access method, victim identification, and the malware's operator.

Legendary Mac Game Celebrates 40th Anniversary With PC Port

Dark Castle, a classic game from 1986, is being re-released as an official port to PC to celebrate its 40th anniversary. Originally developed for Macintosh, the game was notable for its innovative use of animations and gameplay mechanics, despite the platform's limitations in graphics. The game was created by Silicon Beach Software in collaboration with artist Mark Stephen Pierce and programmer Jonathan Gay, utilizing a technique called "page flipping" to enhance performance. Dark Castle is known for its challenging gameplay and has a sequel, Beyond Dark Castle. Both games are now available on Steam, providing a modern way to experience these titles.
