**💻📰 Show HN: Mastra – Open-source JS agent framework, by the developers of Gatsby**
Mastra is a new open-source TypeScript framework created by the Gatsby team for rapidly building AI applications. It provides essential building blocks like workflows, agents, retrieval augmented generation (RAG), various integrations, and evaluation tools. The framework is designed to be opinionated, streamlining development. Deployment options include local machines and serverless cloud environments.
Users can leverage Mastra with several large language model (LLM) providers, such as OpenAI and Anthropic, though obtaining API keys may require credit card information depending on the provider. A command-line interface (CLI) tool, `create-mastra`, simplifies project setup and initiation. The framework prioritizes user feedback in its ongoing development.

**💻📰 Broken legs and ankles heal better if you walk on them within weeks**
Recent research challenges the long-held belief that patients with broken legs or ankles should avoid weight-bearing for extended periods. A shift in medical practice is underway, advocating for earlier weight-bearing, often within weeks of surgery, rather than the previous standard of six weeks or more of immobilization. This approach is supported by studies showing that early mobilization does not increase the risk of complications and significantly improves recovery time and quality of life by allowing patients to resume normal activities sooner.
The outdated practice of prolonged immobilization stems from a cautious approach rather than robust scientific evidence. The benefits of early weight-bearing are demonstrated through improved healing and quicker return to work and other activities. While exceptions exist for complex fractures, the general recommendation is now leaning towards earlier mobilization following a broken leg or ankle.

**💻📰 When imperfect systems are good: Bluesky's lossy timelines**
Bluesky's social media platform prioritized performance improvements in its "Following Feed/Timeline" system. The system previously struggled with high latency, particularly impacting the 99th percentile of response times (P99). To address this, engineers made a deliberate trade-off: sacrificing some data consistency for significantly improved write performance. This involved changes to how posts are indexed and delivered to followers. Instead of ensuring every follower sees a post instantly and perfectly, the system now focuses on efficient distribution, accepting that some minor inconsistencies might occur.
The result was a dramatic reduction in P99 latency—over 96%—without noticeably affecting the user experience. This demonstrates a successful approach to system design where achieving "perfection" across all metrics (consistency, availability, latency, throughput) is impractical. Prioritizing one aspect (write performance in this case) based on its impact on users proved a more effective strategy than striving for perfection in all areas simultaneously. This approach highlights a key principle in system design: finding the optimal balance among competing properties to best serve the needs of the application.

**💻📰 "Ensuring Accountability for All Agencies" – Executive Order**
This executive order, issued by the President of the United States, reinforces the principle of presidential accountability for the actions of all executive branch agencies. It emphasizes that while the President delegates authority to subordinate officers, ultimate responsibility for the execution of laws remains with the President. This responsibility is underscored by the President's accountability to the American people through regular elections. The order highlights the constitutional framework of executive power, emphasizing the President's role and the checks and balances provided by the separation of powers and an independent judiciary.
The order's purpose is to reiterate the fundamental principle of presidential oversight and accountability across all federal agencies. It serves as a declaration of the President's authority and responsibility for the actions taken by those acting under their authority. The order does not detail specific mechanisms for enforcing accountability, but rather asserts the existing constitutional structure as the foundation for ensuring responsible governance.

**💻📰 Multiple Russia-aligned threat actors actively targeting Signal Messenger**
Several Russia-aligned threat actors are intensifying their efforts to compromise Signal Messenger accounts. These actors are primarily targeting individuals of interest to Russian intelligence, such as military personnel, politicians, and journalists. This increased activity is likely a response to the ongoing war in Ukraine, driven by the need to access sensitive communications.
The attacks leverage various tactics and methods to breach Signal accounts, and Google's Threat Intelligence Group (GTIG) anticipates a rise in similar attacks in the near future, potentially extending beyond the Ukrainian conflict and affecting other regions. Signal's popularity among those frequently targeted for surveillance makes it a prime objective for obtaining sensitive information. The ultimate goal is to intercept intelligence that serves various Russian intelligence interests.

**💻📰 Nuclear fusion: WEST beats the world record for plasma duration**
The French Alternative Energies and Atomic Energy Commission (CEA) announced a significant breakthrough in nuclear fusion research. On February 12th, their WEST experimental reactor achieved a world record by sustaining a plasma for over 22 minutes. This surpasses previous records, demonstrating a major advancement in the feasibility of controlled fusion.
The WEST (Tungsten Environment in Steady-State Tokamak) experiment utilizes magnetic confinement to contain and heat plasma to fusion temperatures. The extended plasma duration is a crucial step toward developing sustainable fusion energy, as it indicates significant progress in controlling and stabilizing the plasma for extended periods. This achievement strengthens the potential for fusion power as a clean and virtually limitless energy source.
