Why developers are betting on Postgres for AI

Organizations are intensifying the development of AI applications and agents, which rely on access to existing enterprise data to avoid inaccuracies in responses, a phenomenon known as "hallucination." Jensen Huang, CEO of Nvidia, and Phillip Merrick, co-founder of pgEdge, emphasize that structured data is essential for AI effectiveness. PostgreSQL is highlighted as a preferred database for AI applications, with 66% of respondents in the Stack Overflow 2025 Developer Survey indicating they wish to continue using it. Merrick notes PostgreSQL's advantages, including its open-source model, scalability, and ability to handle both structured and unstructured data. The pgEdge toolkit supports the entire lifecycle of AI application development, including document ingestion and vector embedding generation. PostgreSQL offers deployment flexibility and robust security features, making it suitable for critical sectors like finance and healthcare.

Fix: You’ll need a new app to open this windowsdefender link

The message “You’ll need a new app to open this windowsdefender link” indicates issues with the Windows operating system when the Windows Security app fails to launch via the windowsdefender protocol. This can prevent users from accessing the security dashboard, despite Microsoft Defender continuing to operate in the background. Common scenarios leading to this error include clicking on Virus & Threat Protection, trying to open Windows Security from the Start menu, interacting with a Defender notification, or following the uninstallation of third-party antivirus software. Root causes may include corrupted Windows Security app registration, damaged system files, third-party antivirus interference, misconfiguration of the Security Center service, or malware interference. To resolve the issue, users can verify that required services are running, repair system files using SFC and DISM, re-register the Windows Security app, check for third-party antivirus conflicts, and perform a repair installation of Windows. Specific steps include checking the status of the Security Center and Microsoft Defender Antivirus Service, executing repair commands in CMD, re-registering the Windows Security app using PowerShell, uninstalling third-party antivirus software, and performing an in-place upgrade if necessary.

“The vault is solid, the delivery truck is not” — strong key storage, shaky transfer: why this Windows Recall feature raises new security questions

Windows Recall, an AI-driven tool by Microsoft designed to capture and analyze users' screen content, was initially unveiled in 2024 but faced a delayed rollout due to significant security concerns. It launched in April 2025 with enhanced security features, including isolation within a "VBS Enclave" to protect against third-party access and filtering out sensitive information. However, security researcher Alexander Hagenah identified a flaw where data is transmitted to a less secure process, d AIXHost.exe, allowing tools like TotalRecall Reloaded to access sensitive data without administrative privileges. Despite reporting this vulnerability, Microsoft deemed it "not a vulnerability" and has not planned significant fixes. In response to user backlash, Microsoft is reassessing its AI initiatives, including Windows Recall, while privacy-focused organizations have introduced features to block the tool. Experts are calling for improved security protocols and user opt-out options.
