Fwd: online meetup Wed. 20 Nov. 18h UTC | Green Coding Solutions: "Eco-CI" and "Powerletrics"

[Joseph P. De Veaugh-Geiss]

Hi! I'd like to ask the KDE community to give feedback on a possible eco 
initiative within KDE. The Open Source company Green Coding Solutions 
has a new tool called Eco-CI to estimate the carbon footprint of the 
CI/CD pipeline. Is there support for adopting this tool within the KDE 
community (e.g., for Okular, as proposed)?

FYI if you are interested in talking with the developers directly, join 
the KDE Eco online meetup next week (see below) where Arne and Didi will 
be presenting.

As I see it, benefits of integrating Eco-CI into the development 
pipeline include:

  - Maximal transparency about the embodied carbon of a software 
releases in KDE.
  - Opportunities for data-driven improvement.
  - Quantifiable differences for any changes made to the development 
process.
  - KDE will be a leader in providing data about the carbon footprint of 
our software development.

Drawbacks could include:

  - KDE may be the only organization providing such data and it could 
give negative impressions abut our environmental impact (to note: I 
don't think this is necessarily a good argument, but I can see it being 
one).
  - Discouraging use of the CI/CD pipeline could negatively impact 
software quality.

Other benefits? Drawbacks? Do you support the idea?

More info can be found about Green Coding Solutions and the Eco-CI tool 
at this MR in the Okular repository:

"""
[Eco-CI] integrates into the GitLab CI/CD pipeline and estimates the 
energy and CO2 consumption of the pipeline by utilizing a Machine 
Learning model trained on real server energy data from SPECpower

The tool creates awareness of the energy cost and carbon emissions of 
CI/CD pipelines and empowers developers to create action for more 
sustainability.

If you want to discuss with the Eco-CI developers directly, join us next 
Wednesday 20 November 19h CET (see below for details).

Cheers,
Joseph

After a short three-month hiatus, the next KDE Eco online meetup will be 
Wednesday *20 November* 18-19h UTC! I am excited to announce that Green 
Coding Solutions will present two of their new measurement tools:

  - "Eco-CI" to measure energy consumption of CI/CD pipeline
  - "Powerletrics" Linux kernel extension for power usage estimations

Eco-CI has been suggested for integration into the Okular's CI/CD 
pipeline. For discussion, see: 
https://invent.kde.org/graphics/okular/-/merge_requests/1030

See below for more details.

_Overview_

*When*: Wed. 20 November 18-19h UTC

*Where*: https://meet.kde.org/b/jos-l59-2i1-9yt

*Topic*: Green Coding Solutions tools "Eco-CI" (CI/CD pipeline) and 
"Powerletrics" (Linux kernel extension)

*Pad*: Further ideas are collected at this pad, please add ideas of your 
own:

        https://collaborate.kde.org/s/cactBt4frrfTjbW

*Details*:

Eco-CI [0] is an open source GitHub / GitLab Plugin that estimates the 
energy and carbon emissions of a CI/CD workload. It hooks into the 
pipeline and will print a summary directly in the logs or as a 
downloadable artifact. Arne, one of the core developers, will present 
the tool and show some numbers from repos, including their average 
emissions, to get a feel for the importance of the topic. A discussion 
of integrating Eco-CI into Okular's GitLab repository will follow the 
presentation.

Powerletrics [1] is a kernel extension that brings per process power 
usage estimations to Linux. It is modelled after the MacOS tool 
powermetrics which developers can use to gain insights into their 
environmental impact of their code. With modern ICT infrastructure using 
more and more resources, it is important that there are easy tools for 
monitoring and optimisation available so that we don’t waste precious 
resources.
