There are plenty of problems in the way of measuring the carbon footprint of an IT workload, and I’ve been leading a Green Software Foundation project to make it easier to get better measurements for cloud provider based workloads. Along the way I’m learning a lot about the subtleties of…

Amazon released their 2022 sustainability report which includes an updated list of renewable AWS regions. For 2021 there were 13 AWS regions that were “over 95% renewable”. For 2022, there are 19 regions that are “100% renewable”, notably adding four regions in China and India, and their new regions in…

Like many people, I’ve been tinkering with ChatGPT to see what it can do, but I was working on developing some fairly complex analysis code using the R language that I wanted to talk about and open source as part of the talk I gave earlier this week at Monitorama…

I’ve presented at GlueCon many times over the last decade or so. It’s an unusual event, held at the end of May at an isolated hotel between Denver and Boulder Colorado, the agenda is curated by Eric Norlin, and the 2-day event is run by his wife Kimberley. The theme…

The Prime Video team published this story: Scaling up the audio/video monitoring service and reducing costs by 90%, and the internet piled in with opinions and bad takes, mostly missing the point. What the team did follows the advice I’ve been giving for years (here’s a video from 2019): “Where…

Hertz recently started to rent electric cars, and we’ve tried them out a few times. …

Medium launched me.dm a while ago as a gateway to the fediverse, but I haven’t seen much activity there. Posting here, I don’t see a Toot option, alongside the Tweet/Facebook options. Anyway since I have a separate account from my main account at @adrianco@mastodon.social that lives @adrianco@me.dm I decided to…

We want to reduce carbon emissions of our compute and storage workloads, and one way of doing this is to choose a time and place where the “grid mix” of energy consumed is less carbon intensive. In particular, there is usually an excess of solar energy during the day that…

by Adrian Cockcroft The existing approaches to carbon measurement provide delayed data for carbon accounting that is more akin to billing information in the way it is structured and queried. This proposal seeks to define a standard for real-time carbon and energy data as time-series data that would be accessed…
