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.

Fully Playable Scream Game Found in Steam Leak [2026]

A horror game based on the Scream film franchise was discovered in the Steam data leak that occurred from August 29 to 31, 2026. The game, an unfinished multiplayer prototype created by Fatshark, was found by a Twitter user named Roly Poly Reaper, who managed to run it on their computer and enable online multiplayer. The prototype included several unfinished builds, with one featuring operational networking code that allowed players to take on the roles of survivors evading a player-controlled Ghostface. The project appears to have been a pitch build, never fully greenlit for production, and was stored in Valve’s old Steam2 backend for approximately 15 years before the leak. Roly Poly Reaper used the Goldberg Steam emulator and Radmin VPN to run the game, circumventing the need for a live connection to Valve’s servers. Fatshark, known for cooperative shooters, had reportedly built the Scream prototype around 2011, coinciding with the release of Scream 4. The prototype's existence predates the popularization of the asymmetric horror genre by several years. The Steam2 leak itself involved approximately 12 to 13 terabytes of data, including various internal builds and beta versions from Valve and third-party developers. Valve has not publicly commented on the leak.

Windows could lock you out of your PC. Save your recovery key now!

Device encryption can lead to being locked out of a computer, making it crucial to back up the recovery key in advance. Users with local accounts must ensure they have this key, while those with Microsoft accounts can retrieve it later. Windows 10 and 11 Home editions may automatically encrypt the hard drive. To access the recovery key, users should sign in to their Microsoft account online and note the key ID and recovery key. Multiple devices linked to the same account will be listed online, complicating key retrieval. Each encrypted partition requires a separate recovery key. The OSV refers to the system drive, and FDV refers to other data drives. Without a Microsoft account, users cannot access an online backup of the recovery key, and the Home Edition lacks options for saving the key compared to the Pro version.

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.

Install Windows 11 on Steam Deck OLED: 12 Steps [2026]

The Steam Deck OLED has limitations in running certain Windows applications and games, particularly those with kernel-level anti-cheat systems. Valve has provided an official Windows driver bundle for the OLED model since 2024, and by 2026, a community-developed process for dual-booting Windows 11 alongside SteamOS has emerged. Running Windows 11 may be necessary for games that do not perform well on SteamOS, especially competitive titles. The Steam Deck OLED requires specific prerequisites for dual-booting, including a fully charged device, updated SteamOS, sufficient free storage, a Windows 11 license, and a USB flash drive for installation. Users must follow a detailed installation process that includes updating SteamOS, creating a recovery drive, downloading Windows 11, and configuring the system for dual-booting. Common pitfalls include skipping the recovery drive and under-allocating storage for Windows. Battery life on Windows is shorter than on SteamOS, and users should be aware of this when deciding to dual-boot. The dual-boot setup does not void the warranty, and it is possible to revert to a SteamOS-only setup later.

“God Mode? Hardly.” Microsoft debunks Windows 11’s God Mode, but the trick still works

The "God Mode" in Windows is activated by creating a folder and renaming it to GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}, which transforms the folder icon to resemble the Control Panel and displays a comprehensive list of all settings tasks available in Windows. This trick was clarified by Microsoft engineer Brandon Paddock, who stated that the name "GodMode" is misleading, as the folder can be named anything with the same CLSID code, and it merely exposes two documented elements of the Windows shell. The functionality was intended for developers and not casual users, and the trick could be altered or removed in future updates.

Windows XP’s most famous pirated key wasn’t a hack, and a Microsoft engineer explains why

The FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 key is a notorious Windows XP product key that became widely associated with the operating system, which was released on October 25, 2001. Unlike modern free upgrades, Windows XP required users to purchase a physical copy, making the product key essential for installation. The FCKGW key was a legitimate Volume License Key that was misappropriated and allowed users to bypass Microsoft's Windows Product Activation (WPA) system, which linked product keys to specific hardware to combat piracy. This key was whitelisted in the activation logic, enabling installations without activation prompts. Although it is still technically usable on older discs, Microsoft's servers no longer validate it, and the key has been blacklisted. Microsoft recently released a new version of the Windows Bliss wallpaper to commemorate the 25th anniversary of Windows XP.

Windows XP’s most famous pirated key wasn’t a hack. It was a leak

The product key FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 was originally intended as a valid Volume Licensing Key (VLK) for corporate use and was never meant for casual home users. It was created to facilitate developers' work by allowing them to bypass certain restrictions during testing. The key was later bundled with special volume media and disseminated online, leading to widespread misuse. Windows Product Activation (WPA) generated a unique hardware ID based on the user's CPU, RAM, and other components for validation. The FCKGW key was whitelisted in Windows XP's activation logic, allowing installations to bypass the activation prompt entirely. This oversight enabled Windows XP to function fully without the constraints of a 30-day timer or watermark and bypassed initial validation checks for updates.
