  Evil triumphs when good men do nothing

  I never thought that I would write an article on this site of mine about war, peace and a threat to not only an entire nation's existence, but mine, too. But as this website has some reach (there's around 75 000 of you each month), I feel that I have a responsibility to say and do something. On February 24th, 2022, the fascist oligarchy known as Russia attacked yet another one of its neighbors. That's almost not even newsworthy by itself - it's happened multiple times before.

  "Share to Yammer" truly is gone - what's next?

  This article explains what happened to the "Share to Yammer" button, which was discontinued at the end of Q2 2025, and what you can do now. The historical context Yammer was acquired by Microsoft in 2012. At that time, Yammer was a popular enterprise social networking service, and Microsoft integrated it into its suite of productivity tools. Well, "integrated" might be a strong word. More like "added it to marketing materials". But I digress.

  Extend Your Windows 10 Experience for Another Year 🥰

  This article explains how you can keep using Windows 10 for another year, even though Microsoft has officially ended support for it. Background (rant) I'm not going to lie - right now I would not buy a Windows computer. It just feels like a risk you don't need to take. And I would know! I have bought 3 Windows machines in the last 3 years, costing me (or my employer) 4000, 2500 and 750 euros respectively.

  How to query a term + children in SharePoint Search (KQL)?

  In this article, I'll get back to basics of KQL in SharePoint Online's Search Service, and explain how to target a Managed Metadata term and its children. Maybe everyone else just remembers how to do this straight off the bat, and how the service behaves in different scenarios... But I don't. And googling gave me a bunch of low confidence results. Which I had very low confidence in. So here we are. I needed to try this out again, and document it for future reference.

  LEDs Are Blinking But Nobody's Home - Dell XPS 15

  This article explains how to diagnose and fix a Dell XPS 15 laptop that won't start, indicated by blinking LED lights. It includes a list of blink codes and a step-by-step guide to resetting the BIOS. And a lengthy rant about Dell and the state of Windows laptops in 2020s 🙃 Background Ah, Dell XPS 15, my favorite laptop to hate on. 1.5 years of a love-hate relationship, with very little love and a lot of hate. Don't get me wrong. I have loved Windows since I first got started on Windows 3.11.

  How to authenticate against SAP SF OData endpoints in .NET?

  This article explains how to obtain OAuth access tokens for SAP SuccessFactors OData endpoints using the SAML 2.0 Bearer Assertion flow. I wouldn't normally write about SAP. It's one of the TLAs that gives me shivers, and I'd rather stay away from it. But the corporations do love it - almost as much as they love Workday - so deal with it we must! I'd also normally post my articles on Tuesdays - but this one was so painful to finish that it'll roll out when it's done.

  M365 Skills are all over the place again - what's good?

  This article explains the weird history of the M365 Skills offering, which has been renamed and rebranded more times than I can count. If you want the TL;DR - skip the history and jump to the "What do you need to know about People Skills in M365?" section.

  CollabDays Finland 2025 was amazing! Here are the session materials

  CollabDays Finland/Helsinki was last week, and boy was it an interesting trip! I feel super fortunate having the opportunity to do some fun traveling for work, and the privilege to speak and meet people at these community events. I was presenting a session with Gautam Sheth, an old friend from the fabled Valo days. We talked about our experiences (and challenges) with the M365 Agents SDK, and how to build M365 Copilot extensions with it.

  Why M365 Agents SDK Should Be on Your Radar

  This article explains some of the pros and cons of the M365 Agents SDK: The ambitious successor to Teams Toolkit, and why you should care about it. I'm also sharing some of my and my peers experiences developing with it. Background Microsoft really, really REALLY wants to be THE Enterprise AI company, and place Copilot as the UI for AI.

  First experiences using GitHub Copilot Coding Agent

  In this article, I will share some of my first experiences using GitHub Copilot Coding Agent (or "SWE Agent" as it was known before), and some quick tips for getting the most out of it. Or maybe I'll just be sharing some fun and frustrating moments with the truly Agentic version of GitHub Copilot. Because that's almost as much fun as showing everyone the funny pictures I made with AI, right?

  Microsoft Lens is going away - what now?

  In this article, I'm complimenting Microsoft on making a fantastic app, after which I'll have the questionable pleasure of announcing that the app is going away. Because Microsoft Lens, the app that made scanning, saving and sharing documents and whiteboards a breeze, is being discontinued. Microsoft just can't tolerate an app that does one thing, and does it well. So.. What now? Background Microsoft has officially announced the discontinuation of Microsoft Lens , formerly known as Office Lens .

  Chrome crashing on startup on mac OS? Easy fix!

  This article explains how to fix it when Google Chrome decides to start crashing immediately on startup. Chrome is seriously starting to feel like the Internet Explorer of the 2020s sometimes - yet, somehow, I still keep using it. Background I was surprised to find out that there are a lot of guides for this issue online already.

  Fix 'Invalid Path' Error When Cloning GitHub Repo on Windows

  Let me open up with a few hot takes: Operating System should be an enabler - infrastructure, that doesn't get in the way. Version control should also be an enabler - and at best, a force multiplier. Developers should be able to select their laptops so they'll stay as productive as possible. Fun file names should be allowed. Well, maybe nothing I said was really THAT hot of a take.

  Humbled and Honored to reach my 500th article on koskila.net !

  This article is going to be something a little bit different: I'm still on vacation, but figured I should write sort of a self-congratulatory celebration post for 500 published blog posts on koskila.net, and offer y'all a quick look at what's going on with the site and myself. koskila.net is evolving - after 10 years! If all goes well, you should be noticing some small differences in the layout and all that.

  Am I the problem? Even onboarding to the Apple ecosystem failed miserably.

  I'm on Summer vacation, and I figured it's a good time to do something slightly different - it might finally be a good time to put the finishing touches on this lighter article about my recent forays into the Apple ecosystem. Which haven't exactly been perfectly smooth sailing.

  Any kubectl command throws "Unhandled Error" err="couldn't get current server API group list: Get "http://localhost:8080/api?timeout=32s": dial tcp [::1]:8080: connect: connection refused" - what do?

  This article explains a fix to a - frankly possibly a little bit dumb - problem, where all kubectl commands suddenly throw an error along the lines of "couldn't get current server API group list: Get \"http://localhost:8080/api?timeout=32s\": dial tcp [::1]:8080: connect: connection refused". Since I don't ever have Kubernetes running locally, and I actually don't even change kubectl connections, I was quite confused by this.
