This (free, unlimited) tool has been working well for us - https://github.com/iandees/aws-billing-to-slack.

edit - appreciate that Vantage may have better features, but this gives us a reliable daily cost report on Slack.

Sure, I used Lucid Chart https://app.lucidchart.com which has a lovely set of "flat" AWS asset icons.

This looks interesting, nice work. For comparison, I created a full-stack AWS boilerplate with similar aims: https://github.com/stackplanet/sourcestack

Author here. I built sourcestack as an alternative to AWS Amplify for creating full-stack serverless web apps. Amplify is a great tool, but as it's a high-abstraction framework that hides infrastructure behind libraries and code generation tools, I frequently end up fighting against it when it doesn't meet my requirements.

In my opinion this is the essential and insidious problem of frameworks - they make certain things easy, but they require you to cede too much control and you end up constrained by their assumptions and locked in to their roadmaps.

sourcestack takes a template based, low-abstraction approach that surfaces all infrastructure and common logic as source code within the workspace, giving you complete control over all aspects of your application. It aims to provide a batteries-included, forkable foundation for a web app that encourages adaptation and a deeper understanding of cloud infrastructure. I'm hoping that others might find it useful and perhaps be inspired to create forks or similar templates for other technologies.

The paper discusses the longevity of radioactive isotopes over large time scales - basically only a few isotopes have half-lives long enough to last for tens of millions of years, and those can be created naturally as well as artificially.

On the point about oil, the paper points out that oil deposits have been created cyclically over large time scales:

"At least since the Carboniferous (300–350 Ma), there has been sufficient fossil carbon to fuel an industrial civilization comparable with our own"

There were three anoxic events, where the ocean was completely depleted of oxygen, in the Cretaceous period 132, 120 and 93 million years ago.

"these [carbon] releases often triggered episodes of ocean anoxia (via increased nutrient supply) causing a massive burial of organic matter, which eventually became source strata for further fossil fuels. Thus, the prior industrial activity would have actually given rise to the potential for future industry via their own demise. Large-scale anoxia, in effect, might provide a self-limiting but self-perpetuating feedback of industry on the planet."

Although, as the paper notes:

"Alternatively, it may be just be a part of a long-term episodic natural carbon cycle feedback on tectonically active planets."

Cixin Liu's latest book "Of Ants and Dinosaurs" explores this topic in a very entertaining way: https://headofzeus.com/books/9781789546095

I'd recommmend Sunfall by British physicist Jim Al-Khalili as an entertaining fictional account of the catastrophic effects of an weakening in the Earth's magnetic field, followed by attempts to remotely restart flow activity in the core.

This reminds me of the great short story "The Next Ten Billion Years" by John Michael Greer: http://archdruidmirror.blogspot.com/2017/06/the-next-ten-bil...
