These instructions were originally for my testing of aws/aws-node-termination-handler#669, but I'm putting them here for general reference in the future.

Creating an EKS cluster and installing NTH into it

1. Create an EKS cluster with a managed node group using eksctl

eksctl create cluster --name nthCluster --region us-east-2

# Extract the SHA-256 hash for each version
for i in "${!versions[@]}"; do
    version=${versions[$i]}

Alternative Twitter client to circumvent filtering

If this (http://gigaom.com/2014/09/04/twitter-cfo-says-a-facebook-style-filtered-feed-is-coming-whether-you-like-it-or-not/) comes true, it should still be possible to get an unfiltered tweet stream as long as Twitter doesn’t also tamper with public profiles when the viewer is not logged in. If those still display all of a person’s raw tweets, we can still get the current idea of a timeline.

Basic process

1. Keep a list of all the people you follow
2. Pull down each person’s public profile (cache them, if desired)
3. Filter out tweets starting with an @-mention of anyone you don’t follow
4. Stitch them all together in chronological order
