Sustainable dev environments in the cloud

Is it better to replace powerful developer laptops with cloud dev environments? What is the carbon cost of my software development – builds, tests, deploys, code hosting, dev environments?

Roman Climate Optimum and energy system resiliency

It’s quite easy to argue that modern civilization is much more robust and resilient than any ancient society, but consider how much of our critical infrastructure is written in memory unsafe languages!

Predictions in energy and computing

Is it a good idea to make predictions about future energy consumption? Even mature public businesses typically only issue earnings guidance for the next quarter. Maybe it’s because predicting the future is hard?

How much energy does cryptocurrency use?
