I activated the Linux terminal on my Pixel, and you should too

Google's Pixel devices now include a Linux Terminal app, introduced with the March 2025 Pixel Drop update. This app allows users to access a version of Debian on their smartphones, enabling them to execute commands, install packages, and perform internet-related tasks similar to a desktop Linux terminal. The app is available for Pixel phones running Android 15 or newer and is currently exclusive to these devices. To activate the app, users must enable Developer options, toggle on the Linux development environment, and install the app, which has a download size of approximately 565MB. The feature is experimental and may have bugs, such as persistent notifications and connectivity issues. The app operates within a virtual machine, isolating it from the device's data but allowing access to the Downloads folder.

Securing the Model Context Protocol: Building a safer agentic future on Windows

The Model Context Protocol (MCP) is a lightweight, open protocol functioning as JSON-RPC over HTTP, facilitating standardized discovery and invocation of tools. MCP defines three roles: MCP Hosts (applications accessing capabilities), MCP Clients (initiators of requests), and MCP Servers (services exposing functionalities). Windows 11 will incorporate MCP to enable developers to create intelligent applications leveraging generative AI. An early preview of MCP capabilities will be available for developer feedback. MCP introduces security risks, including cross-prompt injection, authentication gaps, credential leakage, tool poisoning, lack of containment, limited security review, registry risks, and command injection. To address these, Windows 11's MCP Security Architecture will establish security requirements for MCP servers, ensuring user safety and transparency, enforcing least privilege, and implementing security controls like proxy-mediated communication, tool-level authorization, a central server registry, and runtime isolation. MCP servers must comply with security requirements, including mandatory code signing, unchanged tool definitions at runtime, security testing, mandatory package identity, and declared privileges. An early private preview of MCP server capability will be offered to developers post-Microsoft Build for feedback, with a secure-by-default enforcement strategy planned for broader availability. Microsoft aims to enhance defenses continuously and collaborate with partners to bolster MCP's security framework.

Microsoft’s Edit on Windows is a new command line text editor

Microsoft introduced a new command-line text editor, Edit on Windows, during its Build conference. This open-source tool allows developers to edit files directly within the command prompt by typing “edit” and is designed to enhance the developer experience. Edit on Windows is less than 250KB in size and includes features such as key bindings for menu options, support for multiple files with ctrl + P shortcut, find and replace functionality with match case and regular expression support, and word wrapping capabilities. The motivation for creating Edit was to provide a default CLI text editor for 64-bit versions of Windows, which previously lacked an integrated command-line editor. Edit on Windows will be available through the Windows Insider program in the upcoming months. Additionally, Microsoft is rebranding Windows Dev Home to Advanced Windows Settings, which will simplify customization for developers and integrate additional features into the main Windows 11 settings interface.

How to catch and optimize problematic queries in PostgreSQL

Performance issues in PostgreSQL can arise as databases grow, leading to declines in query performance. To identify problematic queries, one can log long-running queries by setting the `log_min_duration_statement` parameter in the `postgresql.conf` file. The `pg_stat_statements` module can be enabled to monitor execution statistics of SQL statements, providing insights into query performance, including execution time and the number of calls. Queries with high standard deviation in execution time may indicate inconsistency, while sorting query statistics by total execution time can reveal excessive load from multiple fast queries. Real-time monitoring can be done using the `pg_stat_activity` view to check active queries and their states, and the `pg_locks` view can help identify blocked processes. The `EXPLAIN` command can analyze query execution plans, and using the `auto_explain` module can log plans for slow queries. Understanding cost parameters in query plans helps in optimizing performance, and different join methods (Nested Loop, Merge Join, Hash Join) have varying complexities and costs. To influence the planner's choice of scanning methods, configuration parameters can be adjusted, such as disabling sequential scanning. Extensions like `sr_plan`, `pg_hint_plan`, and `AQO` can further optimize query execution. Monitoring query progress can be done using dynamic views like `pg_stat_progress_*` for various commands.
