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.

Scammers Impersonate Microsoft to Push Fake Security Scans and Refund Fraud

A network of fraudulent websites, branded as SysScan, has been discovered, which falsely claims to evaluate antivirus software effectiveness through deceptive security scans. These sites manipulate users into uninstalling legitimate antivirus products and disclosing sensitive personal and banking information. Eleven distinct domains associated with SysScan have been identified, all hosted on a single server. The fraudulent scans generate misleading results based on static findings rather than actual system assessments, and users are coerced into believing their computers are at risk. The scams misrepresent normal browser behaviors as security threats and instruct victims to uninstall their antivirus software, compromising their defenses. The operation targets both individual and business users, collecting extensive personal information and utilizing remote-access tools. The data submitted is sent to Telegram via its bot API. Users are advised to disconnect from the internet and secure their devices if they suspect they have been compromised. Indicators of compromise include specific IP addresses and domains associated with the scam.

Game of Thrones: War for Westeros isn’t even out yet and it already feels ancient

Game of Thrones: War for Westeros is an RTS game set to release in 2027, inspired by HBO's series. The game revisits the struggle for the Iron Throne, allowing players to command characters like Kit Harington's Jon Snow and listen to narration by Charles Dance. Gameplay involves constructing buildings, generating resources, training troops, and capturing territories, but it primarily features standard infantry units like spearmen and swordsmen. Only two factions, the Starks and Lannisters, are available in the preview, with the Starks able to deploy direwolves and the Lannisters focusing on economic strategies. The game lacks the excitement and complexity found in other RTS titles, feeling straightforward and uninspired, with gameplay that does not leverage the source material's strengths.

Windows 11 KB5121003: Game crashes caused by inpoutx64

Microsoft has acknowledged issues with the August security update KB5121003 for Windows 11, affecting versions 24H2 and 25H2. Users reported problems such as game freezing, unexpected closures, and system restarts after installing the update. The issues are linked to drivers and software for specific RGB-enabled peripherals or components, particularly involving the inpoutx64.sys driver. Games mentioned include ARC Raiders, MARVEL Tōkon: Fighting Souls, and THE FINALS. Embark Studios has released a support guide suggesting users stop and remove the inpoutx64.sys service as a temporary workaround. Microsoft is investigating the issue but has not provided a definitive fix or patch timeline.

Windows NT 4 went on sale 30 years ago today

Microsoft Windows NT 4.0 was officially released on August 24, 1996, marking its 30th anniversary today. Codenamed “Tukwila,” it integrated the Windows Explorer desktop from Windows 95 with the NT operating system. Windows 95 was released a year earlier on August 24, 1995, and was initially codenamed “Chicago.” Windows NT 4 incorporated a modern user interface while maintaining the reliability of the NT kernel. It introduced features like the journaling NTFS filesystem but had limitations such as stability issues due to changes in the Graphics Device Interface (GDI) and lack of support for FAT32 and USB interfaces. Despite these shortcomings, NT 4 was a significant operating system that contributed to the competitive landscape of operating systems.

Windows 11 Update Breaks Games: The RGB Fix

The cumulative update for Windows 11, KB5121003, has caused game freezes and crashes for users, attributed to conflicts with third-party software and drivers managing RGB components, particularly related to the inpoutx64.sys file. Affected games include ARC Raiders, MARVEL Tōkon: Fighting Souls, and THE FINALS, with symptoms such as unresponsive games, sudden closures with an EXCEPTIONACCESSVIOLATION message, and unexpected system reboots. Microsoft has not provided a permanent fix but suggests users report issues via the Windows 11 Feedback Hub and consider removing or renaming the problematic driver as a temporary measure.

Microsoft blames RGB peripherals for crashing Windows 11 — RGB software is causing blue screens, crashes, and game freezes

Windows 11 users are experiencing system instabilities, including game freezes, crashes, and blue screen errors, following the KB5121003 update. The issue is linked to RGB software that conflicts with essential system components. Affected online multiplayer games, such as Arc Raiders and Marvel Tokon: Fighting Souls, are particularly impacted, with players encountering "EXCEPTIONACCESSVIOLATION" errors. The problematic driver, often named "inpoutx64," is associated with RGB lighting control and operates in kernel space, leading to vulnerabilities that anti-cheat mechanisms aim to mitigate. When the driver is blocked, it causes critical errors resulting in system crashes. Microsoft has suggested temporary workarounds using compatible programs like SignalRGB or OpenRGB to manage RGB devices without triggering anti-cheat alerts. Users are encouraged to report issues through the Feedback Hub for resolution prioritization.

Star Wars Zero Company And Galactic Racer Clashed, Lucasfilm Could Have Prevented It

Two Star Wars titles, Star Wars Zero Company and Galactic Racer, are set to launch within months of each other, marking the first time in 15 years that games from different developers will share a release year. The simultaneous lifting of embargoes for both games occurred just an hour apart, creating a clash that disadvantaged the team behind Galactic Racer. The two titles are developed by independent studios Fuse Games/Secret Mode and Bit Reactor/EA, respectively, with Lucasfilm Games overseeing the process. The marketing strategies for the games have differed, with Zero Company announced at last year's Celebration and Galactic Racer unveiled in December. Star Wars Zero Company is set to launch on August 27th, while Galactic Racer will follow on October 6th. Pre-orders are available for both titles.
