SDIA Green Coding Summit

23-24 November 2023, Berlin

Watch the recordings

We brought the leading-edge expertise within the software community, both European and International, together in one place to amplify knowledge sharing, debate, and create unity during our conference hosted at Berlin's iconic Französischer Dom on 23-24 November 2023.

Learn

At our conference we showcased and shared the extensive work being developed by the thought leaders advancing Green Coding tools & practices.

Connect

Participants had the opportunity to expand their knowledge of the key challenges, case studies, and tools available to address the environmental impact of software.

Code

Our Bootcamp deep dives with our leading European green coding experts enabled participants to learn, code, and ask questions and work on their own projects.

A European Green Coding Summit with Knowledge & Action

As the software community is becoming more aware of the importance of knowing the environmental impact created by their work, a European Summit was needed. Participants sought to understand why environmental impact matters, how it can be measured, and learn active solutions that can be implemented to create positive change. 

Organizations and software communities across Europe recognized the environmental impact created by software itself during the Summit. They learned how to quantify and reduce those impacts during our Bootcamp Labs.

Most importantly, it was fun and engaging: See our photos, recordings and presentations below.

Bootcamp Labs

Lab 1: Green Coding Berlin will introduce its Green Metrics Tool, EcoCI and other methods for measuring environmental impact on the backend

First session: introducing hardware and software concepts to read energy data with further steps to convert it to CO2 metrics. Also indirect energy metrics from network and cloud services are discussed with current approaches to approximate them using linear and non-linear machine learning models.

Second session: the Green Metrics Tool and ECO-CI will be used hands-on to measure container based software as well as a standard Github/Gitlab CI/CD pipeline. The hands-on session will feature setting up these tools, generating measurements, comparing metrics and understanding typical caveats when conducting energy and CO2 measurements of software.

Lab 2: The Green Web Foundation (TGWF) will introduce open-source tools & approaches for Green Web Development

First session: introducing the ways different models for measuring carbon work, and helping developers take their first steps using an existing established open source tool, WebPageTest - which consumes the CO2.js library to provide software carbon calculations. TGWF will share how they see people using these tools in teams, and the alternatives available.

Second session: showing how tools that exist in browsers now offer direct measurement for carbon calculations, and how to use them. TGWF will show developers how to use the profiling tools now built into the open source browser Firefox - which also consumes the CO2.js library to provide these calculations.

Lab 3: Boavizta will introduce its tools for environmental impact monitoring tools & APIs and will host a special session on measuring AI models

First session: General impact assessment with Boavizt API, Scaphandre as well as Energizta and other Boavizta tools to implement general environmental impact monitoring into the operations of software applications.

Second session: For AI Developers - combining BoaviztAPI + CodeCarbon to monitor AI models' environmental impact during development and training, using Scaphandre and the nvidia_gpu_exporter for inference monitoring.
