Quote of the Week

Using R or Numpy is like driving around in a sports car. You just turn the wheel, press the pedals, and burn rubber. Rust (and other systems languages) are like getting a spaceship. You can go places and do things that you never dreamt of in a car. They are harder to pilot, but the possibilities seem unlimited! With the Rust ecosystem still in development, it feels like parts of your spaceship come in boxes of parts labeled "some assembly required".
