Rusty's API Design Manifesto

The idea

Application Programming Interface (API) design is hard. But it's even harder to change once you get it wrong. So what you should do is to spend the effort to get it right the first time around.

In the Linux Kernel community Rusty Russell came up with a API rating scheme to help us determine if our API is sensible, or not. It's a rating from -10 to 10, where 10 is perfect is -10 is hell. Unfortunately there are too many examples at the wrong end of the scale.

Rusty's original descriptions

• Descriptions of the positive API levels

Animate the connectors

Animating your connectors is great for demonstrating directional flow charts, electrical circuits and more. To animate your connectors:

1. Click on the connector you wish to animate. Hold Ctrl or Cmd and click to select multiple connectors
2. On the right-hand side go to Style > Property and click on the arrow to expand the field
3. Scroll down to Flow Animation and check the box
