Every Rust reply when someone suggests C# is now: “Why would I choose C# when even @stephentoub chose Rust?” Whatever reasoning comes after that line, the line still wins. Making the case for .NET just got harder. That hurts. Toub’s write-ups are the ones we quote to defend the choice. This feels like et tu, Brute. First Anders takes the TypeScript compiler to Go. Now Toub takes the Copilot runtime to Rust. These don’t happen in a vacuum. An ecosystem was built, people bet their careers on it, and the person we pointed to as the “why C#” priest just picked a different church. @shanselman this doesn’t stay in a blog post. The ecosystem you helped grow is the one we have to defend in comment sections tomorrow, and the citation we used just walked off the stage. If Microsoft is porting, it's mission critical infrastructure to non-.NET languages, do I need to be worried about building my clients mission critical infrastructure on .NET?

I am thinking of changing my login screen to: No offense to dotnet team ...you know right tool for right job and all.

Midnight is to Zcash what Ethereum is to Bitcoin.

We are aligned :P

I feel like everyone is trying to read the tea leaves in a tornado right now.

Exciting day for NVIDIA and @huggingface. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. They allow every developer, startup, university, industry and country to build with, customize and benefit from AI. Thank you @ClementDelangue for coming to me. NVIDIA is going to be a great home for Hugging Face, its community and the future of open models. 🤗 blogs.nvidia.com/blog/nvidia…

You can now run Cursor cloud agents on your infrastructure, including pools of machines that automatically scale with demand. This lets you give agents access to internal services or specialized hardware, while the agent loop stays in Cursor.

AI response of the day :)

Origin, our code hosting platform, is now live. It's fast, easy to use, and deeply integrated with Cursor. Get started by syncing your repos from GitHub.

Grok 4.6 is live.

making software easier to build is just flat out a good thing

One of the best is available. Reach out now and thank me later.

Excellent article and attitude. Making C# even more awesome. Thanks.

‼️ BREAKING: An active npm supply chain attack has compromised at least 868 packages carrying over 2 billion monthly installs with a credential-stealing worm. Shai-Hulud is back. It started with the compromise of the GitHub account of the maintainer behind keyv, a library with roughly 127 million weekly npm downloads. A preinstall hook fires on npm install and drops a stealer that sweeps npm, GitHub, AWS, Kubernetes and Vault secrets, and then spreads to more maintainers.
