AWS CloudWatch Alarm Mute Rules eliminate alert fatigue - devamazonaws.blogspot.com

Amazon CloudWatch now supports Alarm Mute Rules, enabling customers to temporarily mute alarm notifications during planned deployments, maintenance windows, and off-hours without compromising monitoring visibility. This new capability helps eliminate alert fatigue while maintaining complete situational awareness across their infrastructure. Alarm Mute Rules transform operational workflows by allowing teams to create one-time or recurring rules that silence notifications for up to 100 individual alarms around deployment calendars, scheduled maintenance activities, or predictable off-hours periods when non-critical alerts become disruptive. Customers can configure actions for OK, ALARM, and INSUFFICIENT_DATA states, and when mute rules expire, any previously muted actions are automatically triggered as long as the alarm remains in the same state it was in when the actions were muted, ensuring critical issues are never overlooked while preventing unnecessary alert fatigue. This elimin...

[MS] How can I distinguish between the numeric keypad 0 and the top-row 0 in the WM_CHAR message? - devamazonaws.blogspot.com

Last time, we looked at how to distinguish the numeric keypad 0 and the top-row 0 in the WM_ KEY­DOWN message . We may as well look at the analogous table for WM_ CHAR . Event wParam Extended? Numpad0 with NumLock on VK_0 0 Numpad0 with NumLock off (no WM_CHAR ) Ins key (no WM_CHAR ) 0 on top row VK_0 0 I got the name VK_0 from this comment block in winuser.h . /* * VK_0 - VK_9 are the same as ASCII '0' - '9' (0x30 - 0x39) * 0x3A - 0x40 : unassigned * VK_A - VK_Z are the same as ASCII 'A' - 'Z' (0x41 - 0x5A) */ Uh-oh. The extended bit doesn't distinguish between the two. They both show up as VK_0 , non-extended. What changes is something not in the above table: The scan code. So let's convert the scan code back to a virtual key. auto vk_from_scan = MapVirtualKey((lParam >> 16) & 0xFF, MAPVK_VSC_TO_VK); Event wParam Extended? vk_from_scan Numpad0 with NumLock on VK_0 0 VK_INSERT Num...

Amazon Bedrock AgentCore Browser now supports proxy configuration - devamazonaws.blogspot.com

Amazon Bedrock AgentCore Browser now supports customer-provided proxy configuration, enabling customers to route browser sessions through their own proxy infrastructure for geo-targeting, regional content access, and compliance requirements. Organizations can access geo-restricted content, verify region-specific pricing, and validate localized application behavior across markets. Customers in regulated industries such as healthcare and financial services can route traffic through corporate proxy infrastructure to meet security policies while automating critical business processes. Browser proxies help eliminate re-authentication cycles due to rotating IPs, while providing stable, controllable egress addresses for IP allowlisting requirements. The feature currently supports both HTTP and HTTPS protocols with secure credential management through AWS Secrets Manager. This enhancement is particularly valuable for healthcare organizations accessing portals with strict IP allowlisting, fin...

[MS] Handling Legacy User Settings in SharePoint Framework - devamazonaws.blogspot.com

Introduction The SharePoint Framework (SPFx) has undergone some important changes in how it handles Entra ID app registration and security models. Here you can find additional details about what was updated and about the new application IDs used by SPFx. These changes have important implications for developers who previously relied on legacy user settings stored through the old application registration model. This article explores the technical challenges and provides practical solutions for handling legacy user settings when transitioning to the new SharePoint Framework security architecture. Understanding the SharePoint Framework Security Model Evolution The Legacy Application Model Previously, SharePoint Framework utilized an application called SharePoint Online Client Extensibility Web Application Principal . This application had several key characteristics: Tenant-specific registration : The application was automatically created in each customer tenant when they began using S...

[MS] Build Intelligent Apps with SQL: Join the SQL + AI Datathon - devamazonaws.blogspot.com

Image
The SQL + AI Datathon is a hands‑on challenge designed to show how the foundations for building modern, intelligent applications with SQL. Over a set of guided missions and a focused open hack, you’ll learn how to combine SQL with embeddings, semantic search, and Retrieval Augmented Generation (RAG) to build real AI‑powered experiences. The SQL + AI Datathon puts SQL at the center of the architecture. You’ll learn how to: Use SQL as a reliable, secure data source for AI workloads Implement RAG (Retrieval‑Augmented Generation) so AI responses are grounded in your data Build AI experiences that scale from prototypes to real applications Who Should Participate? The SQL + AI Datathon is designed for: Developers curious about AI Developers building AI applications with real data Anyone interested in trying out the new AI Features in SQL Server 2025 Any beginner thinking about how to get started with data powered AI applications for free Learn Along the Way with the Reactor Se...

[MS] How we built the Microsoft Learn MCP Server - devamazonaws.blogspot.com

Image
When we launched the Microsoft Learn Model Context Protocol (MCP) Server in June 2025, our goal was simple: make it effortless for AI agents to use trusted, up-to-date Microsoft Learn documentation. GitHub Copilot and other agents are increasingly common, and they need to be able to ground responses just like humans with browsers do. Learn MCP Server is a remote server that exposes agent-friendly tools over Streamable HTTP Transport, backed by the same Learn knowledge service described in How we built “Ask Learn” . Why MCP and why Learn MCP Server? Modern AI agents can discover and use tools dynamically through Model Context Protocol , a standard that lets agents negotiate capabilities at runtime, stream results, and adapt as tools evolve. Instead of manually searching, scraping pages, or maintaining embeddings, clients simply connect to Learn MCP Server, request the list of tools available and invoke tools as the agent decides. VS Code GitHub Copilot and other MCP Clients can deli...

[MS] Beyond the Prompt - Why and How to Fine-tune Your Own Models - devamazonaws.blogspot.com

Image
Large Language Models (LLMs) have reached a point where general intelligence is no longer the bottleneck. The real challenge in enterprise AI systems behavioral alignment ensuring models that produce consistent, reliable, policy-compliant outputs on a scale. Prompt engineering and Retrieval-Augmented Generation (RAG) are powerful but they do not change model behavior. Fine-tuning will solve this by customizing a pretrained AI model with additional training on a specific task or dataset to improve performance, add new skills, or enhance accuracy. This post explores what Microsoft Foundry fine-tuning is, when using it, the fine-tuning approaches it supports   and code examples on how to run Fine-tuning on Microsoft Foundry. What Is Microsoft Foundry Fine-Tuning: Microsoft Foundry fine-tuning allows you to customize pre-trained foundation models (OpenAI and open models) using task-specific datasets, producing a specialized model that behaves predictably for your use case while mai...
