With pain in my heart, I have to tell you that the love of my life, Arjen Smits aka Danthar, has past away on october 31, 2025. He fought a battle he couldn't win. 💔 Julie Smits

the best thing .NET Aspire does well is eliminate the insane productivity-killing manual process that every BigCo has for getting their $100m app running locally This talk is about using .NET Aspire to avoid that. Will do YT videos about it in near future too.

The deeper you go into the semiconductor supply chain, the less believable it becomes. > TSMC, a company on a small island, produces over 90% of the world’s most advanced chips > TSMC relies on dutch company ASML for EUV lithography machines > ASML depends on German Company Carl Zeiss, the only firm in the world capable of making mirrors precise enough for ASML’s requirements. > The light source for ASML’s EUV machines is produced by a single company in San Diego. > The photoresists used to print transistor patterns are produced by Japanese firms like JSR and Tokyo Ohka Kogyo. > The ultra-pure quartz needed to make silicon wafers comes entirely from a single mine in Spruce Pine, North Carolina. > The copper and rare-earth materials inside chips are mined and refined across Chile, the Congo, and China. > The specialized gases used in chipmaking, like neon and fluorine, largely come from Ukraine and Japan. > The design blueprints for these chips often come from American companies like NVIDIA, AMD, and Apple, which rely on software tools from U.S. firms like Synopsys and Cadence. Remove any single piece and the whole system collapses.

In de tweede aflevering duiken we in de veiligheid van ons stroomnetwerk: hoe makkelijk is dat te hacken, en hoe kwetsbaar zijn we? We spreken erover met experts, hackers (o.a. @SchizoDuckie) en onze minister. De episode is nu overal te beluisteren: open.spotify.com/episode/2gCDhc…

Did you check out the new IExceptionHandler in .NET? It's a simplified way to handle exceptions globally. IExceptionHandler is part of the built-in exception handling middleware. You can handle all exceptions or a specific exception. Which also means you can chain handlers. Want to learn more? Here's an in-depth article: milanjovanovic.tech/blog/global-er… What are you using for exception handling? I've switched all my APIs to the new exception handler and haven't looked back. --- Sign up for the .NET Weekly with 74K+ other engineers, and get a free Clean Architecture template: milanjovanovic.tech/templates/clea…

Don’t sleep on Mapsui. It is my favorite .NET library for cross platform maps and works everywhere. Just restarted project sponsorship. github.com/sponsors/pauld…

Thats a shame because it was a way better movie. Then i thought it would be. I enjoyed it and will gladly. Tecommend watching it

@James_M_South @Aaronontheweb Yes the hubris is astounding. They think going commercial is a cash grab. They have n no idea of the effort involved to maintain these projects.

@Aaronontheweb The hubris is astonishing. We’ll fork multiple specialist projects with no prior experience and definitely succeed to maintain them indefinitely “better” than the original maintainers.

Ah cool, so I suppose .NET users are going to run out and start contributing to / donating to projects with FOSS licenses - right? .... Right?

The built-in "Eventing Framework" issue in dotnet/aspnetcore was closed last night as "not planned." This is a tragedy for the least capable users in our ecosystem, having to resort to *shudder* evaluating mature third party frameworks to do the same thing.

Spent the past few weeks re-designing the website for Phobos, our commercial library for Akka .NET telemetry, and I think it might be the best looking DocFx website on the market:

@DaemnProgrammer @s_l_barth @meticulous @FlorisGroen For sure!

@s_l_barth @Danthar @meticulous @FlorisGroen Ikr? I hope you guys had a nice afternoon as well. Nothing quite like enthusiastically opinionated rantings and discussions on topics between like-minded geeks. 😎

@DaemnProgrammer @Danthar @meticulous @FlorisGroen It's been a long time since we last got together. How about having a new "Coffee & Code" meeting? I suggest to do so in Den Bosch. Date still to be determined.

Made a very short video (<3m) on trying to get the OTEL Collector to work with .NET Aspire, because I wasted several hours trying to make this work this week.

Don’t take it from me: take it from the ChatGPT team explaining how it al works under the hood It’s not a fellow human, even though it can generate text much better than any other machine learning approaches. blog.pragmaticengineer.com/how-does-chatg…

David Fowler ( @davidfowl ) went from an intern to a Distinguished engineer at Microsoft. That’s 11 different promotions all at the same company. I interviewed him for everything he learned by going through that process. We discussed: • His promotions to Principal and Distinguished • Concrete examples of Distinguished+ engineering • Big company tips he's picked up • How Microsoft's culture changed since Satya became CEO • Career regrets and work life balance • Advice for new grads If this sounds interesting to you, here's where you can see the full conversation: • Youtube: youtu.be/d8tRM8RJ52M • Transcript: developing.dev/p/intern-to-mi… • Spotify: open.spotify.com/show/0MX9PyeCz… • Apple: podcasts.apple.com/au/podcast/the…

Incrementalist 1.1 is out and live on NuGet - if you've never heard of it before, it's an OSS dotnet tool for doing incremental builds on really large .NET solutions (monorepos especially) - it leverages git diffs and Roslyn to cover the minimal graph needed to cover changes

Your .NET apps need a reverse proxy. Why? - Secure entry point - Central auth & TLS (termination) - Load balancing - Request aggregation I just dropped a video showing how to build one with YARP in ASP.NET Core. Check it out: youtu.be/DcIi-XPqmTQ

@DaemnProgrammer @s_l_barth @meticulous @FlorisGroen Yes I'm in

@s_l_barth @Danthar @meticulous @FlorisGroen Do-able, as far as I am concerned.

@s_l_barth @DaemnProgrammer @meticulous @FlorisGroen Noted!

@Danthar @DaemnProgrammer @meticulous @FlorisGroen Ok, let's make it 7 september! That's next Sunday. Same time, 11:00h, at Pilkington, Den Bosch. I'll log back in here tomorrow night to see if we all agree.
