Consul Consistency

As Kyle brought up, Consul at the moment has a single known case of a potential inconsistency (Could be unknown cases lurking). Currently Consul works by electing a leader, who "leases" the position for LeaderLeaseTimeout interval. At each interval, it checks that a quorum of nodes still believes it to be the leader. At the same time, if a follower does not hear from the leader within randomInterva(HeartbeatTimeout, 2 * HeartbeatTimeout), it will start a new election.

Abby is talking about speed of feedback. Why would we invest in something high quality if we have no idea if it is going to work? In the Agile world, Fast in exchange for Quality certainly does appear - we just call it "Prototypes" or "Spikes". Those are specifically designed to eliicit feedback without spending a ton of time on a solution we may or may not need.

Lean Startup principles take that a bit further - build something quickly to get feeback so that you know if the direction you are going in is the right one. That gives you customer feedback - and dollars - to be able to build a high quality solution. If something has bugs or doesn't work correctly for all cases, who cares if we are directing people only down one path to see how they respond to the system?

Like spikes, it has the danger of turning into the final product, at which point quality is a big concern. But I see no problem with advising customers who are tryi

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
