GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

How to create a publicly-accessible SNS topic that sends messages when objects are added to a public Amazon S3 bucket.

1. Create something within AWS that triggers notifications.

In this case, that's an S3 bucket that is continually updated by the addition of new sensor data. For the purposes of this tutorial, we’ll use s3://noaa-nexrad-level2 – one of our NEXRAD on AWS buckets – as an example.

2. Create an SNS topic and appropriate policy.

The SNS topic should be in the same region as the bucket. It will need to have a policy that allows our S3 bucket to publish to it, and anyone to subscribe to it using Lambda or SQS.
