In an earlier version of the article the calculation statement contained a message about us being confused why the conversion factor is 277000000. Thanks to Silas Duddeck from the Goethe University in Frankfurt who pointed out that the factor should be 1J = 2,777778⋅10-7kWh = (1/3600000)kWh => 277777777 [...]

In my last blog post I have written about how we finally completed the DC measurement reporter for our Green Metrics Tool. In the last days we have looked at reducing the variance of the ATX powerlanes and finding out if swapping out the resistors for more stable current measurement resistors can improve the measurement. [...]

We finally got our DC measurement setup ready … sadly around one month later than expected. If you wanna see first results go here: Wordpress sample measurement Stress sample measurement If you wann get the details of our journey, why we are integrating it into our tool, some tech specs and the future outlook on when we have the AC measurement ready, then read on :) [...]

Starting this month we will be releasing articles in a regular fashion about insights into energy use of specifc software tools or architectures. In order to lay a foundation to follow these articles we have created at a CO2 Formulas page, where you can find all the relevant formulas how to calculate the energy use of software. Often times software can be directly instrumented and measured, but when the complexity gets too high (in network transmissions) or data is limited (in the cloud) then often assumptions are made. [...]

Today we have have released the 0.1-beta version of our Green Metrics Tool Version 0.1-beta is considered a non-production version. [...]

Today we have pushed the first beta of our metrics providers for full OS Intel RAPL readings. You can see the full details of our demo runs with the static version of the Green Web Foundation Page in our Green Metrics Tool Repositories Overview [...]

How many times do we use Youtube only to listen to songs, or to watch videos without the necessity of going for that fancy 4k/HD resolution? Also: do we really want to automatically watch other (algorithmically-chosen) videos after the current video is finished? In other words, how can we have a carbon-friendly approach while still getting the content we wanted? [...]

As some of you following our Green Coding github have maybe noticed is that we have changed the license of some of our repositories. The tools and the demo code where prior licensed under MIT, which is a software license that we have come to love through popular libraries like Ruby on Rails, Bootstrap, Joplin and many more … [...]

What exactly is green coding? Green Coding means the practice of software development with a strong focus on resource efficiency in terms of energy use. It is also known as green software engineering or green software development. [...]

Today we have big news which shine a light on what we have planned for the coming months. Green Coding Solutions is becoming a legal entity in form of a non-profit [Green Coding Solutions gGmbH]. [...]
