Where does a developer's responsibility begin and end when it comes to managing the success of a product? This question has been nagging me for the better part of a year now, and I hope that expressing my thoughts will help cement my thoughts on that particular issue. I've been fortunate enough to work in many environments with varying levels of product responsibility.
Experiments with the new WASI workload in .NET 8 Preview 4
.NET 8 adds a new "wasi-experimental" workload, replacing the earlier Wasi.Sdk. This is a step towards giving .NET native, built-in support for server-side WebAssembly scenarios.
This video shows how to get started, then demonstrates how .NET+WASI creates possibilities for new kinds of apps and new ways to use .NET.
While Rust has earned a dedicated following, it's not without its fair share of controversies and problems. In this video I'll talk about the negative response and backlash from the Rust community in the wake of the most recent controversy, its connections to past incidents, and give my personal thoughts.

On 16th November 2016, Nat Friedman and James Montemagno introduced Visual Studio for Mac, the newest member of the Visual Studio family at Connect(); 2016 event. I thought let's give it a try so I installed the same and went through the project templates available in it. This blog is kind of a getting started guide to install Visual Studio For Mac.
