If Argentina would have played like the last 10 minutes, it would have been an interesting game. Now, Argentina was for 110 minutes a pure disgrace for the sport. Very much well deserved win for Spain

Just out of curiosity When building .NET projects (APIs), and you want to deploy them as a container. To you prefer 'dotnet publish' or a dockerfile to build and push a container image to a registry?

I have never done anything with WASM, so I tried creating a DJ Controller. Drag your own MP3s to either one of the two decks to analyse the tracks BPM and key, and make professional transfers (sort off), everything client side. All analysis are Rust, frontend Angular github.com/nikneem/wasm...

ADRs don't fail because they are bad, they fail because no one reads them. The solution? Make AI read them. In my latest post I describe an MCP Server to feed your architectural decisions into Copilot and I think it's pretty nifty: hexmaster.nl/posts/mcp-se... #AI #MCP #Copilot #Documentation

Level up local-first, cloud-ready dev with #Aspire + #Dapr. I built a small chat app to show how Aspire’s #AppHost orchestrates #services and #emulators in one command, while Dapr sidecars add pub/sub and state so you can swap Redis/Azurite for cloud services without code changes. bit.ly/aspirechat

Happy to share I finished my demo app for an upcoming conference talk. It's .NET #Aspire with #dapr running a distributed (event-driven maybe) chat server, and obviously a front-end that allows you to actually chat. Runs locally, planning cloud deployment sometime soon: github.com/nikneem/aspi...

Doesn't is make sense to -When you use .NET Aspire and Azure Table Storage- to also create the tables, storage containers etc. in the Aspire host? @davidfowl.com @damianedwards.com I think this is infra work, can solve it with createIfNotExists(), but requires my app to have too much privileges.

Tomorrow, the Aspire team with @maddymontaquila.net broadcasts a live stream to Aspirify an app. I will join them to see if we can optimize the developer experience of an existing app and see what #Aspire can really do. Maybe @davidfowl.com or @damianedwards.com chime in as well?
