Ghost: A Database for Our Times?

Ghost, developed by ghost.build, is an "agent-first" Postgres database platform designed for AI-related applications, allowing developers and AI agents to create, fork, inspect, query, manipulate, and delete databases easily. It is free to use and hosted on Ghost’s Cloud infrastructure, making it suitable for testing, prototyping, and disposable database environments. Users can create databases on demand, execute SQL queries, and discard them when finished, contrasting with traditional managed databases. Ghost integrates with AI tools like Codex and Claude Code, providing direct database management capabilities through its MCP server. To install Ghost, users need a supported coding agent and a GitHub account. Installation commands differ for Linux, macOS, and Windows. After installation, users can verify the Ghost MCP server and interact with it through their coding agents. Examples of using Ghost include creating a sales data database, utilizing Ghost CLI commands, and experimenting with databases through AI agents. Ghost allows for rapid database manipulation and is ideal for proofs of concept and experimentation, although caution is advised before using it for production data.

Backstage Ditches Postgres for Databricks Lakebase

The divide between operational and analytical databases is diminishing, as evidenced by Databricks integrating Spotify's Backstage with its Lakebase, transitioning from PostgreSQL to a unified data platform. Lakebase now offers a serverless PostgreSQL interface within Databricks, allowing Backstage to operate without awareness of the underlying changes. The integration involved updating configurations and addressing authentication challenges using OAuth JWTs. The integration transforms the database development lifecycle by enabling near-instant database branching through Lakebase's copy-on-write architecture, allowing developers to focus on testing changes rather than safety. Branching creates a pointer to existing data, making the operation instantaneous. Point-in-Time Recovery (PITR) allows for quick restoration of data, demonstrated by a recovery process that took less than four seconds. The goal is to integrate database branching into developer workflows seamlessly, making it automatic. This change could enhance developer productivity by allowing live data testing from the start, eliminating the need for mock objects, and resolving common issues related to staging environments. The traditional constraints of slow and costly database copies will become obsolete, prompting teams to reconsider how much time they spend on workarounds for now-nonexistent constraints.

Windows AI Recall is pushing data destruction upstream

The introduction of Copilot+ PCs has created new complexities in IT asset disposition (ITAD), as these devices may contain a comprehensive, time-stamped archive of user activity, which was not present on corporate laptops two years ago. Microsoft's Recall feature captures user activity screenshots and stores them securely, but recent research by Alexander Hagenah suggests that the safeguards may be ineffective, as his tool can extract sensitive data without breaking encryption. Microsoft defends the security of Recall, stating that observed access patterns align with intended protections. This situation presents challenges for ITAD operators, as pre-collection now constitutes a data-destruction event, requiring devices to be powered down or purged before leaving the client’s environment. Certificates of sanitization must evolve to address the specific destruction of Recall snapshot stores, and conversations with clients should differentiate between managed and unmanaged fleets regarding Recall settings. The presence of Recall shifts some data-destruction responsibilities upstream to clients, complicating traditional ITAD value propositions.

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.

Windows 11 KB5083769: The April Update may require the recovery key on certain BitLocker-enabled systems

The April update KB5083769 for Windows 11 versions 24H2 and 25H2, released on April 14, 2026, has a known issue where certain devices may enter BitLocker recovery mode after installation. This problem affects a limited subset of devices with specific, non-recommended BitLocker Group Policy settings. The issue arises when BitLocker is activated, a specific TPM platform validation policy is set to include PCR7, PCR7 binding is not feasible, the Windows UEFI CA 2023 certificate is present, and the device is not using the 2023-signed Windows Boot Manager. Microsoft advises organizations to review their BitLocker Group Policy settings and verify PCR7 binding status before deploying the update to prevent devices from requesting recovery keys. If the recovery prompt appears, users will need to enter the BitLocker recovery key, but subsequent reboots should not trigger the recovery process again if the Group Policy remains unchanged.
