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.

The state of Myo bindings in Node.js

... any takers? Comment on this gist! The discussion all started from a Tweet:

Who's going to be the first to write a wrapper for the @thalmic #myo C++ library? Latest headers: https://gist.github.com/indexzero/60d1224f0082f0d16f14

As pointed out by @c4milo there are a number of libraries that exist, but from first glance they all have deficiencies:

• https://github.com/HektorW/myo-node: Only works on Windows
• https://github.com/KamalAman/Myo-Node-Red: I don't even understand how this works
