Notes from the distributed matters 2015 conference.

Jepsen V (Kyle Kingsbury)

Talks about how Jepsen works and what systems have been tested until now, among others:

• Riak: default is last-write-wins, but you should not be using it
• ZK: works as advertised (!)

... But all of this is also on his blog, not anything really new.

A short introduction to Datadog functions

You can apply functions to metric queries in the graph editor, as long as you use the JSON editor.

The general format is:

function(metric{scope} [by {filter}])

In case of binary operators (+, -, /, *), the format is:

Rich Hickey on becoming a better developer
