  Home Automation - an air quality comparison

  And now for something completely different! I had a disagreement with my wife a while ago. See, I've long suspected that our old house - originally built in the 1950s - has an air quality problem. Just a minor one, but still a problem. I say minor because, according to my measurements, pretty much the only issue is that in two rooms, the HVAC system isn't able to circulate air almost at all (which isn't surprising considering there are neither air inlets nor outlets in those rooms!

  See you at CollabDays Madrid on 4.6.2026!

  If you're anywhere near Madrid on June 4th and enjoy Microsoft 365, Copilot, developer tooling, or just a good tech event with smart people in the room, this is your cue: come join us at CollabDays Madrid 2026 . This week I'm traveling to Spain to speak at CollabDays Madrid, and I'm quite excited - it will be my first time speaking at an event in Spain, and my first time visiting Madrid. I will be talking with my good friend Michäel Maillot about M365 Agents SDK again.

  Are we learning anything from the recent GitHub hack?

  A week ago, GitHub announced they've been hacked. A hacker group called TeamPCP had extracted roughly 4000 private repositories and who-knows-how-much more data from GitHub's internal systems. This sounds like a pretty big deal (and it is!), but I fear we're not taking the right lessons from it. GitHub accidentally open-sourcing their internal systems? Sure, that'll lead to future breaches. But the attack vector?

  The "Canva Button" kerfuffle is everything wrong with software in 2026

  So this week, I'm writing about something completely different. And not something nice. No, this week, I'm writing about licensing. I hate licensing. But I also hate search engines and AI assistants not being able to come up with clear answers about simple questions - and that is exactly what happens when you search for "Canva Button" today.

  M365 Agents Toolkit Azure provisioning failures

  In this article, I'll share the least fun error I've recently had to deal with while building / deploying bots - I mean, agents - with Bot Framework, I mean, Microsoft 365 Agents SDK on macOS. And of course how to get around the issues. Because if I didn't find a workaround, I wouldn't be sharing this, would I? No, I would be crying about it on a GitHub issue or LinkedIn or something. Both of which I kind of did, but I also found a workaround, so here we are.

  GitHub Copilot's Freemium Era Is Over

  A week ago I wrote about how the all-you-can-eat AI buffet is seemingly coming to an end, and how practically every major AI vendor has been tightening the screws. I noted that Microsoft looked like a relative outlier — still following the all-inclusive (for M365 Copilot) or generous grants (GitHub Copilot's "Premium Requests") models, while competitors were moving to token metering. Well, that didn't last long.

  How to install Copilot Studio Agents in Teams (even when it fails)?

  In this week's article I'm sharing some of my experience with installing Copilot Studio Agents in Microsoft Teams. Namely, how to install them even when Teams says "no". Background So you have built a beautiful Copilot Studio Agent, and now you want to use it in Microsoft Teams. How do you get it there? Well, you of course navigate to "Channels" and select "Teams and Microsoft 365 Copilot" as the channel type.

  No, New Outlook (NEW) still can't subscribe to an online calendar

  This article explores the problematic task of adding an online calendar to New Outlook (NEW), and how to work around the issue by using Outlook on the web (OWA) instead. Background Now, unlike in Windows (at least in theory), on a Mac you can't change the default calendar app to something else than Apple Calendar. So if you click on a calendar link in an email, it will open in Apple Calendar - and if you want to subscribe to an online calendar, you better subscribe to it in Apple Calendar.

  USA - giving strong 'Not This Year' vibes 🥲

  What exactly is happening in the USA? The once-great country seems hell-bent on shooting themselves in the foot again, again and again, and knowing what a bad shot most people are, I've chosen to stay out of the line of fire this time around and canceled my travel plans. It bleeds my heart not to make it to the MVP Summit in person to meet up with all the amazing people, and of course to take the excuse to go on a little road trip to check some of the missing states off the map.

  Happy 25th birthday, SharePoint! 🎉

  This article is my love letter to the 25-year-old workhorse in the Microsoft ecosystem - SharePoint. Let me take you on a wild ride through my personal journey and love-hate relationship with SharePoint! Intro So on March 2nd, 2026, SharePoint turned 25 years old. It can now not only drive, but also vote and drink - hopefully not at the same time, even if drinking and voting DOES sound like a great time! My first day job in 2011 was a SharePoint developer.

  Thank you Cloud Tech Tallinn 2026!

  Ever had one of those conferences that are fun, informative, and did I say - fun? No matter whether you're a speaker or an attendee, Cloud Tech Tallinn 2026 was one of those! For me personally, what started as "hey, we should geek out on this new AI stuff" with Michael Maillot over half a year ago, turned into 45 minutes of pure Microsoft 365 Agents SDK goodness - and chaos! - complete with a demo that actually worked (yes, really!

  How to edit members in a M365 Group or Distribution list?

  Stop sending mail to the wrong people because Microsoft buried the controls behind two completely different and hidden UIs. This guide shows how to edit members of M365 (Unified) Groups and classic Distribution Lists using Outlook Web and the Exchange admin center, safely and without accidentally granting Teams or SharePoint access to your entire vendor list.

  What do you do when AKS randomly changes IP address?

  A working service can stop answering overnight when the IP beneath your AKS ingress changes — and when DNS records or firewall rules depend on that address, the fallout can be immediate and painful! This article explains why AKS sometimes changes public IPs, how to tell whether your cluster uses a single address or separate inbound/outbound addresses, and practical steps to prevent surprises or recover quickly when the IP does change.

  Copilot, Blazor, and a Mac Mini in a Pear Tree — koskila.net in 2025

  It’s that end‑of‑year ritual again — a short pause to look back at what actually happened, what broke, and what was surprisingly useful. This year mixed wins with plenty of frustration: Frustration with unreliable hardware and Windows, cold start with macOS, the challenge of balancing family, work, and personal projects with speaking at conferences again; and of course the ongoing learning path with agentic software development.

  My 2025 Holiday Special - Windows 11 set-up fun!

  My Windows 11 machine decided to go belly up just before Christmas, so I got to have some fun reinstalling Windows from scratch. I was hoping for a MacBook Pro for Christmas, but alas - it seems that Satan got me a fresh Windows installation to deal with instead. In this article I'll describe what happened and share my experience setting up a fresh Windows 11 installation — it wasn't pleasant. Maybe this will serve as feedback for Microsoft to improve the Windows setup experience.

  Sharing your meeting recordings has never been more... Confusing!

  This is not my typical blog post, where I introduce a problem, talk a little bit about the background, dive in to the technical stuff, rant for a while and then explain how to get around the issue (or even fix it!) No - this time, in the spirit of ranting, I'm just venting. Well, and in the process I do share what actually does work - so I guess it IS a normal blog post after all. But it IS rantier than usual. You have been warned!
