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.

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.

Minecraft 26.2 Snapshot 5

The 26.2 Snapshot 5 introduces several new features, including an explosive archetype for the Sulfur Cube and the addition of erupting Geysers formed by Potent Sulfur. The new Sulfur Cube archetype, called Explosive, shares properties with the Regular archetype but has higher air drag and can absorb TNT blocks. When primed, absorbed TNT has a fuse time of 6 seconds when ignited by fire or Redstone, and a randomized fuse time between 0.75 and 3 seconds when primed by an explosion. Sulfur Cubes with absorbed TNT cannot be picked up or damaged, and no Small Sulfur Cubes will spawn upon explosion. Potent Sulfur creates Geysers when placed above a Magma block and under water, sending water particles skyward at random intervals. Various adjustments have been made to mob hitboxes, and Hoglins are now classified as hostile and will not spawn on Peaceful difficulty. New sounds for Geyser eruptions have been added, and Touchscreen Mode has been removed. The Data Pack version is now 104.0, and the Resource Pack version is 86.2. New particles related to Geysers have been introduced, and several bugs have been fixed in this update.

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.

Signal isn’t broken — so how are hackers targeting the world’s ‘most secure’ chat app?

On April 26, hackers allegedly linked to Russian groups targeted the Signal messaging app with phishing attacks aimed at senior politicians. These attacks did not compromise Signal's end-to-end encryption; rather, they deceived users into providing access to their accounts through fake messages. Signal is operated by the non-profit Signal Foundation, founded in 2012 by Moxie Marlinspike with funding from Brian Acton, a co-founder of WhatsApp. Signal distinguishes itself by rendering metadata invisible to its operators, unlike WhatsApp, which shares user data with its parent company. Signal's president, Meredith Whittaker, advocates for data privacy.

CanisterSprawl: pgserve Compromised on npm: Malicious Versions Harvest Credentials and Exfiltrate to a Decentralized ICP Canister

On April 21, 2026, compromised versions of pgserve (1.1.11, 1.1.12, and 1.1.13) were published on npm, containing a 1,143-line credential-harvesting script that executes during the postinstall phase of npm install. The malware functions as a supply-chain worm, reinjecting itself into other packages if it finds an npm publish token. Stolen credentials are encrypted using RSA-4096 and AES-256 and exfiltrated to a decentralized Internet Computer Protocol (ICP) canister. The last legitimate release was v1.1.10, published on April 17, 2026. The malware was detected by StepSecurity AI Package Analyst and Harden Runner, which flagged the compromised versions as Critical / Rejected and confirmed live exfiltration during analysis. The injected script performs operations such as harvesting environment variables, collecting filesystem secrets, encrypting payloads, and propagating to other npm packages and Python packages if a PyPI token is detected. The exfiltration domains have been added to a global block list.

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.

Microsoft confirms AI agents are still coming to the Windows 11 taskbar as it prepares for public rollout

Microsoft is integrating AI agents into the Windows 11 taskbar, allowing users to invoke these agents, including third-party options, directly from the taskbar. This feature will be optional and not enabled by default. The AI agents, such as Microsoft 365 Researcher, can operate autonomously to perform tasks like planning, researching, and executing actions without user intervention. Users can activate these agents by hovering over the Microsoft 365 Copilot icon on the taskbar. The Microsoft 365 Researcher can conduct complex research tasks and generate reports using files from OneDrive or Microsoft 365, but it requires a Microsoft 365 subscription to access. A new feature called ‘Ask Copilot’ may enhance the search experience by allowing users to tag and trigger agents using the “@” symbol. This functionality is supported by the Model Context Protocol (MCP), which connects AI models with applications and files. Developers can integrate their agents using the Windows.UI.Shell.Tasks API. Despite earlier statements about reducing AI in Windows 11, Microsoft is adopting a more selective approach to AI integration, ensuring that the use of taskbar agents remains optional and not intrusive. The company is phasing out Copilot branding in certain applications while maintaining AI capabilities in a streamlined manner.
