Navigating the New AI Landscape: A Developer’s Journey Through the Noise
In this article, I share a developer’s perspective on navigating the ever-expanding landscape of AI tools. Grounded in the familiarity of .NET, we explore how Microsoft’s ecosystem—from Semantic Kernel and GitHub Copilot to MCP Server, Fabric, and low-code platforms—offers not chaos, but clarity. With the right mindset and the right tools, the AI frontier becomes not overwhelming, but empowering.
Sharepoint WorkBooks
I currently have multiple Excel Workbooks that are at multiple locations throughout my area that feed back to my master workbook. I have them all linked. I have to do this monthly so I have to create new month workbooks. The problem is when i save a copy of the current workbooks it starts changing this months information. All I want to do is copy all the information on the workbooks, but change the date without it updating anything else.
dotnet maui blazor hybrid for Local viewer.
Hi Everyone, `Preformatted text` I am a dotnet Developer.

Pipeline Extraction Step Fails: Archive File Not Found
Issue Summary The archive file is not found during the extraction step in the pipeline, causing the task to fail. Steps to Reproduce Run the pipeline with the ExtractFiles task configured to extract a previously archived file. The task attempts to locate and extract the file from the expected directory. The extraction step fails due to a missing or inaccessible archive file. Expected Results The extraction step should successfully locate the archive file and extract its contents. Actual Results The pipeline fails at the extraction step. The archive file is not found at the expected location. Error Details Relative file path: _$(Build.BuildDefinition)/80-build/80.zip resolving to: /home/vsts/work/r1/a/_$(Build.BuildDefinition)/80-build/80.zip Error Message: Error: Specified archive: /home/vsts/work/r1/a/_$(Build.BuildDefinition)/80-build/80.zip cannot be extracted because it cannot be accessed. Error: ENOENT: no such file or directory, stat '/home/vsts/work/r1/a/_$(Build.BuildDefinition)/80-build/80.zip'
Please suggest “A Basic Understanding of Python” via Microsoft Learn
I’ve seen many posts and discussions about beginner Python courses on Microsoft Learn, such as “A Basic Understanding of Python” or " take your first steps with Python" (https://learn.microsoft.com/en-us/training/browse/?WT.mc_id=academic-77958-bethanycheum). Could you please suggest a working link to study basic Python on Microsoft Learn? All the links I found in previous posts are not working.
