Meta loses 20 million users across WhatsApp, Facebook, Instagram and Messenger: Here’s what the company is blaming for this drop

Meta has reported a loss of approximately 20 million daily active users across its applications this quarter, attributing the decline to ongoing internet disruptions in Iran and restrictions on WhatsApp in Russia. The company plans to spend between billion and billion this year to support AI initiatives, which is an increase from earlier projections. Meta is also facing legal challenges regarding youth safety, warning of potential material losses due to ongoing lawsuits. To manage its finances while investing in AI, Meta is reducing its workforce by laying off about 8,000 employees and canceling plans to fill 6,000 open roles.

Inside the Architecture of an MCP Server for PostgreSQL

The Model Context Protocol (MCP) serves as a standard interface between large language models (LLMs) and external systems like PostgreSQL, emphasizing the importance of control over mere connectivity. An MCP server must act as a mediation and policy layer, enforcing security boundaries and ensuring that connections default to read-only. It should validate AI-generated SQL as untrusted input, encapsulate queries within transactions, and apply execution-time controls. The server must separate query generation from execution approval to manage operational costs and enforce guardrails on query types, such as limiting the number of rows returned. Token efficiency is crucial, with design considerations for compact data representation and schema introspection. In production, connection management is vital to prevent data leakage among multiple AI agents, and observability through logging executed queries and metadata is necessary for debugging and compliance. Long-running sessions require support for paginated responses to manage context effectively. Overall, the MCP server must integrate security, query safety, token efficiency, and observability into its design from the outset.

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.

‘A performance tool that requires a graduate seminar before breakfast has already lost the room’: Why Windows Task Manager looks like it’s getting CPU usage wrong

Users have expressed frustration with Windows 11's Task Manager CPU usage reporting, believing it relies only on base clock speeds. Dave Plummer, the original architect of Task Manager, indicated that discrepancies may arise from average calculations and inherent compromises in the metrics. In response, Microsoft announced a fix in a recent Preview build, stating that Task Manager will now use standard metrics for CPU utilization across all pages to align with industry standards. Plummer also suggested a distinct Windows mode for power users to enhance flexibility.
