First release of PowerLetrics
- by Didi Hoffmann

Measuring the resource consumption of software is quite a complex topic. When we started working on the Green Metrics Tool we couldn’t imagine the ride this would take us on. From studying the Linux Kernel to building out own cluster. [...]

When does it make sense to replace old hardware from a CO2 impact perspective
- by Didi Hoffmann

A friend recently sent me a news headline in which a company is promoting that they will use their servers 15 years. While this initially sounds like a great idea, once you think about it, for a little while, you realize modern servers are far more energy efficient than old ones. [...]

Releasing Green-Coding.AI
- by Didi Hoffmann

Artificial Intelligence is on the rise and it is using huge amounts of resources. [1] [2] [3] People are still debating on how much, but it is clear that it is quite a lot. [...]

🇩🇪 Green Coding Studie
- by Arne Tarara

Wir sind von der dena (Deutsche Energie Agentur) beauftragt worden, eine hoffentlich bahnbrechende Studie zum Thema Green Coding als Standard in der Softwareentwicklung für eine stromsparende Gestaltung der Digitalisierung zu erstellen. [...]

How much energy is my server using?
- by Didi Hoffmann

Something we often encounter when talking to clients is that they often have no idea of how much energy the various components in their pipeline use. We have developed multiple projects like Eco-CI that measures the energy usage of CI/CD pipelines or Power Hog which logs energy consumption on desktops. [...]

Scale your CPU according to the Grid intensity
- by Didi Hoffmann

In the age of digital revolution, our reliance on technology is ever-increasing, but so is our carbon footprint. Amidst this tech boom, a pressing question arises: how can we leverage technology to combat, rather than contribute to, climate change? [...]

Getting high grade cpu utilization values on MacOS
- by Didi Hoffmann

CPU utilization is an interesting value to use if you ware interested in either energy usage or optimizing your code. We have written a long case study on if it is useful in the first place. [...]

PNG. A message from the past and how to kill it
- by Didi Hoffmann

While reading this great article https://evanhahn.com/worlds-smallest-png/ about the smallest png image possible I started thinking about how old the png standard is and how many more newer formats are out there. [...]

Benchmarking code optimisation
- by Didi Hoffmann

Standard benchmarks play a pivotal role in the field of software engineering, serving as a foundational element for ensuring quality and efficiency. The Transaction Processing Performance Council (TPC) benchmarks, in particular, have established a high standard across the database sector. [...]
