Amazon WorkMail

From Setting up IMAP for Amazon WorkMail:

Configuration	Value
Protocol	SMTPS (SMTP, encrypted with TLS) - not STARTTLS!
Port	465
Username	Amazon WorkMail account
Password	Amazon WorkMail password

This example uses istioctl as the formula, but this may come in handy for kubernetes-cli, kubernetes-helm, etc.

Find the formula for your executable, e.g. istioctl, and click on the link to GitHub:
```
brew info istioctl | grep Formula
```
Click "Blame" button ("History" will be too large to display).
Hopefully, you can find an earlier versioned commit message... click on it.
Click ... in upper-right of next page, select "View File" from drop-down.
Right-click "Raw" button, and Copy URL Address.

From your iOS device, go to Photos, then:

Select
Select All
Share (box w/arrow)
Save Images
Save to Camera Roll
... then plug your iOS device into your Mac and upload the photos to a known location
Disable My Photo Stream in settings on all your devices

Creating an EKS Cluster

Configure aws credentials:

brew install awscli
aws configure

Install eksctl and create cluster:

If you use elasticsearch-curator on AWS (or possibly other hosted or self-hosted Elasticsearch installations that use SSL,) and you get this when curating:

elasticsearch.exceptions.ElasticsearchException: Unable to create client connection to Elasticsearch. Error: Root certificates are missing for certificate validation. Either pass them in using the ca_certs parameter or install certifi to use it automatically.

Then make sure the client.use_ssl key is present and True. This is a non-obvious error that led me down a rathole of Googling. Don't bother specifying root certificates, or installing certifi (it's probably already installed, if you installed elasticsearch-curator with pip.)
