Killed by Microsoft is the Microsoft graveyard; a free and open source list of discontinued Microsoft services, products, devices, and apps. We aim to be a source of factual information about the history surrounding Microsoft's dead projects. 

Take a dive into this history of blockchain technology, a decentralized and distributed ledger. Hear how blockchain has evolved to where it is today and imagine what the future might hold. 

Ryan Dahl, the creator of Node.js, is currently working on Deno, a new runtime for JavaScript and TypeScript, built using V8, TypeScript, and Rust. A 30-minute overview talk. 

So stay tuned for those details. A follow-on .NET Core 3.1 release -- which will include late bug fixes and more, and, who knows, maybe a stable Blazor WebAssembly -- is scheduled for November.  

We strongly believe in a long-term value of this project. A code base in managed code is more approachable for developers and thus easier to extend and maintain.
