    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.

    CollabDays Finland 2025 was great - get the slides and demos here!

    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.

    M365 Agents SDK SSO broken - how to fix it?

    There are a lot of ways SSO can break for your bot or agent on Teams/M365 Copilot/any other M365 app. I don't even know how to explain the extensibility in M365 now, so this word salad is what you get. Anyway in this article, I'll explain how to fix one of the possible ways your setup might be broken. Background I've been working on and off with M365 Agents SDK (and Teams Toolkit before) for a while now, and have some strong opinions about it.

    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.

    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.

    Sideloading Teams apps suddenly blocked? YES it's broken.

Problem For some background, my tenants have sideloading (uploading custom Teams apps) enabled: But when you're trying to Upload an app, it'll tell you sideloading is disabled anyway (that's what "Request approval from your IT admin to be able to upload apps.

    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.

    How to set Outlook as Your default email client on a mac (because that's definitely a totally sensible thing to do)

    This article explains how to commit a crime so heinous Steve Jobs would throw a backflip in his grave: start using Outlook as the default mail app on your mac. But, as I've discovered is OFTEN the case with macs, changing default apps isn’t always as intuitive as you’d hope. Few things are. And don't get me wrong - I'm not saying Windows is intuitive.

    GitHub Actions build for Blazor Static (or rather StaticBlazor) never ending? Super-easy fix!

    This article explains how to fix an issue where a BlazorStatic build job running on GitHub Actions never finishes. It's a puzzling case, but can't really blame GitHub for this one. Can't actually blame anyone but myself, now that I think about it. But enough about that. What's the issue look like? Background Now that the biggest craze on static websites is long gone, I'm jumping on the bandwagon. After evaluating other options, I ended up going with BlazorStatic - a library built on Blazor.

    Help! My OneNote just turned into "Sticky Notes" - what do?

    This article explains how to "fix" (I use that word very loosely here) your OneNote when it suddenly goes bonkers, losing all of the controls and becoming this weird floating ancient thing that the boomers used to call "sticky notes". It's out of control, floating somewhere on your screen, insufferably difficult to actually navigate and to do anything with. Annoying. Background

    This article explains how to search through all of your workbooks in OneNote for Mac OS. The same thing you can do with CTRL+E on Windows - that is. Because for whatever reason, in OneNote for Mac, it's hidden. Background (and problem) Oh, OneNote for Mac, my dearest... Why must you be the neglected sibling of the Windows version? It’s like Microsoft gave it a pat on the head and said, “You’ll get there someday, champ.” But someday never comes. And that's rare!

Mostly installing npm packages, that is. I've posted about the performance improvements before: Dev Drive performance increase in real life scenarios Background I've been using a Dev Drive for my npm -heavy workloads for about half a year now.

    Frontmatter Fields Not Populating When Setting Up Your BlazorStatic Website? Easy Fix!

    This article explains a quick fix to FrontMatter fields in a solution not getting populated when using BlazorStatic. I ran into it after repeatedly exporting all of my stuff from my legacy WordPress site to my in-the-works BlazorStatic site. StaticBlazor is a game-changer for developers who want the power of Blazor combined with the simplicity of static site generation. However, like all powerful tools, it comes with a learning curve.

    Outlook doesn't show flagged emails as tasks

    I feel like this is a regression in the "New Outlook (New)"©, but I could be wrong. Not sure if it worked in the client before, but it definitely did work in the "Outlook Classic (New)" (which is the legacy version of Outlook), and it isn't working in the new app now.
