HAL: AWS s3-sns based single-slack-command bot to handle your VPC

         · ·      · · · · · · · ·

Introduction I recently build a Slack command to help me handle actions on my VPC. The only thing you need is an AWS account - Free Tier it's ok. I recently wrote about how to maximize resources, with particular focus on the number of hours you have in Free Tier - using specific CloudWatch Rules.

It was fun, but not so much as playing to videogames born a few years before I was born. In the 80s, there were not yet the powerful graphics chips that today can be found with a few hundred euros.

The problems of life Each of us has dreams, aspirations, hobbies, interests, but also hundreds of deadlines, a thousand commitments, ten thousand thoughts, a hundred thousand different problems to cope with every day. I am a computer scientist and personally all these things in my life translate into a huge pile of [things/books/articles/guide/blogs] to read, which by the way are very often interrelated. The situation is more or less this:
