The Future of Rust

Let me first point out the obvious: yes, the title is a little sensationalist. Also you might be asking why I should be entitled to talk about the future of Rust.

Launching a URL Shortener in Rust using Rocket

One common systems design task in interviews is to sketch the software architecture of a URL shortener (a clone, if you may). Since I was playing around with Rocket – a web framework for Rust – why not give it a try? More »
