PerfView can record all managed exceptions in all processes system-wide thanks to the .NET ETW provider, with callstacks. I built a viewer for these .etl files:

Heraskevych’s choice to forfeit the medal chance instead of give up the memorial helmet is the biggest story in Ukraine today. Everyone is heartbroken but there is a unanimous consensus that this was what had to happen rather than to give up.

What It Took to Implement VS Code Debugging for .NET nanoFramework buff.ly/Vy8azto #dotnet #IoT #nanoframework #vscode #debugging #csharp

Corporations. Need. To. Start. Paying. I for one will think twice before open sourcing anything non-trivial in the future.

Here is one of the dumbest things about vibe coding that I don't see a lot of people talking about Imagine you're an open source maintainer and someone opens up a pull request against your repository that they vibe coded. They may or may not tell you they vibe coded it; it doesn't really matter… 🧵

Rewatched Tetris last night (what a great movie!), and fell into a Wikipedia hole reading about Robert Maxwell. Turns out he died by jumping or falling off his yacht that was named in honor of his daughter, Ghislaine Maxwell.

I have always said it, I will continue to say it, we are limiting the productive potential of millions of freaks by demanding they earn a wage to survive instead of enabling them to do whatever thing their brain is broken for

Big news! 💪 We’re proud to announce a 2-year sponsorship of ControlR — backing open source and building better remote control experiences in RDM. 🚀🤝 devolutions.net/blog/2026/01...

The wait is almost over! I'm excited to be joining Microsoft Fabric as a senior software engineer. I'm grateful for this opportunity to tackle new challenges together with an amazing team, stretching the limits of .NET build technology! I'll also continue as a member of the C# language design team.

Retired. Thanks for all the fish!

Cloned a project. Project doesn't build. Delete global.json. Project builds fine. It's just a gift that keeps on giving.

My latest side project, this takes an MSBuild binlog file and transforms it into a Perfetto trace msbuild-binlog-perfview.pages.dev

I guess I didn't talk about this much publicly — I, uh, wrote a static site generator last year, to replace hugo and docusaurus for ink & switch. I think the ratio of "niceness" / LOC is really high. Also, I think the readme is a good read. You can take it, hack it, and use it yourself. <3

You and your wife drop your 6-year-old off at school. You just moved here. You see ICE terrorizing your new neighbors. You film them, as is your legal right. Your wife complies with orders. She is then shot in the head. You still have to pick up your child later today. This could be you.

Intuition is all you need. Math is the language of the universe. We made it feel terrifying. It doesn't have to be. Made a thing 💜 unmath.ai Share with someone who was tricked into thinking math wasn't for them!

It’s a dark night when you look at the news and are forced to admit that you no longer believe in the power of the FIFA peace prize
