Development Norms

A common set of development norms

Adhering to a common set of developer norms is a vital factor when a team of people is trying to produce high quality, timely, business critical software.

I'm regularly asked to work on codebases that do not conform to any known measure of coding standards.

Issues include, but are not limited to:

  • no linting
  • no, or few, or inadequate levels of automated testing

A React wrapper for the MetaMask Fox logo
/**

* use <Fox followMouse slowDrift />

This is the shell of my Game server built using Sinatra and EventMachine Websockets. I am trying to extract the cookie information that is passed to the Websocket's `onopen` method via the `handshake.headers['Cookie'], but have been unable to work out how to properly decode the cookie.
