#52 Sustainability at WordPress: an update with Csaba Varszegi, Nahuai Badiola, and Nora Ferreiros
“Today I learned that we have a sustainability team.Thank you for your effort in this area, looking at results of the team so far, and the ROI of time invested, it's probably a good time to officially dissolve the team entirely”.
In 3 sentences, almost 3 years of work from the WordPress Sustainability Group vanished and their Slack channel archived on the spot. To get clarity on what happened at WordPress and to understand what a WordPress practitioner can do to reduce the environmental footprint of her digital services, Gaël Duez welcomes 3 of the 4 founders of the original sustainability team: Csaba Varszegi, Nahuai Badiola, and Nora Ferreiros.
In their much more nuanced exchange that could have been expected due to the current situation, they covered many topics including:
👏 The power of applause to kick start a sustainability team
🔧 How changing HTTPS check made WordPress save 471 kWh / month
🌱 The importance of having sustainability tools as close as possible to software practitioners tools
🏛️ The subtle art of creating a foundation while keeping control over it via intellectual property
🎁 How to “enforce” contribution in an open source community
And much more!

#51 Exploring the digital revolution paradox from a UN perspective with Paz Pena and Pablo José Gamez Cersosimo
It’s a 252 pages report with the foreword of António Guterres, the Secretary-General of the United Nations, talking about digitalization and sustainability. And, for once, it’s not another report from the UN stating “let’s digitize everything to boost sustainability”. Quite the contrary as it states a “unequal ecological exchange between developed and developing countries regarding digitization”. To discuss this “scientific report based on an ethical approach” as he described it, we welcome one of its contributors, Pablo José Gamez Cersosimo, based in the Netherlands. Another contributor, Paz Pena Ochoa, based in Chile, joined us to share her unique perspective on Latin America.

#50 Is Eroom's law the future of Moore's law? with Tristan Nitot
Moore’s law is dead! Long live Eroom’s law!
This provocative statement from Tristan Nitot highlights the pivotal role of software engineers in our journey as an industry toward a sustainable and more frugal digital world. The majority of our old devices, from smartphones to desktop, still work. How come that we waste such a massive gathering of precious resources such as minerals, energy, water and even our human time which we use to manufacture and maintain them? What should we do to break the trend of electronic waste and the ever-increasing footprint of the IT sector on our physical world?
Gael Duez sat down with Tristan Nitot to start answering these questions in this Green IO episode where we covered:
⚖️ Why Wirth’s law matters more than Moore’s law
🗑️ How the Auvergnat cultural aversion for waste accelerated the birth of the Eroom’s law
🔎 How to find (sustainability) weakness in your software,
🐍 Why Python is not (always) guilty of being resource hungry and how to embrace a wise use of alternative libraries such as Polars,
✨The real ROII of using AI to optimize software.
Green IO with Gaël Duez explores how to reduce the environmental impact of our digital world. Twice a month, on a Tuesdays guests from across the globe share insights, tools, and alternative approaches, enabling all responsible technologists, within the Tech sector and beyond, to build a greener digital world, one byte at a time.
