On an OLED display, the wagtail.org dark theme clocks in at 4.4W power use – vs. 7.6W for the light theme! A chill 40% #sustainability improvement for one visit to one site, but this adds up fast at the scale of tens of thousands of sites and millions of users. Lots of potential here – if you want your site’s themes checked, do tell!

From @hannahritchie.substack.com "My overall takeaway is pretty consistent with the reports above: in many cases (but not all) second-hand #electric cars are now cheaper upfront than #petrol [#ICE] equivalents. At the very least, I think it’s fair to say that they're cost-competitive. I think public perception is probably the opposite: there is still a dominant narrative that electric cars are much more expensive. "

I attended NTNU Energy Transition Conference 2025, where experts, politicians and industry leaders are discussing the future of sustainable energy. It brought some insightful discussions on energy systems, innovation, and climate solutions.

US has now exited the #WTO (World Trade Org.) #GPA (General #Procurement Agreement) which Reagan & Thatcher effectively wrote as a central pillar of neoliberalism & which monetarised all values. #US has consistently opposed consideration of other values #sustainability, #ecology, #human values, EDI etc. which globally others have sought.
With US exiting into isolationism huge opportunity now arises for a global reset.
US corporate capital has been looting & pillaging for too long.

How I Gave My Old Computer Parts a Second Life

At the end of last year, we replaced our PCs that were over 10 years old. And with new equipment there is always the question: What to do with the old one?

We haven’t had the best experience of trying to sell old PCs in one go. So throw them away? But … they work quite well! It would be sad to see them just go to the bin. Also, it just felt wrong to throw away fully functional discs, RAM and graphics cards.

So I decided to try a different approach this time. Disassemble the machines and put all the parts up for sale on eBay separately. Not with the aim of making a lot of money, but to avoid electronic waste. – I took pictures of all the parts, gave them a (really) short description and put them up for auction on eBay for €1. The SSDs and HDDs were reset/overwritten and put online with the corresponding SMART values. I didn’t want to cheat anyone who bought a used disc.

If the parts didn’t sell within a few weeks, I could always throw them away. If each item sold for €1, it wouldn’t justify the effort, but at least the parts could stay in use! Maybe someone just wants to try / learn how to assemble PCs. You likely wouldn’t want to buy brand new components for that, right? Who knows (and actually I don’t care).

The Result: after about 3 weeks, to my surprise, almost all the parts were sold! The mainboard and the DVD burner sold for 1€ and 2€ respectively, but all the other parts sold for more.

And I admit: it was also a bit fun to disassemble the machines.

A fresh #Introduction post for a fresh start here:

I’ve spent most of my tech career in open source. I’ve written some good code, but I tend to find my strengths are in developing teams and leveling-up the people on them so I currently work as a VP for small startup.

I care pationately about #sustainability and humane tech, even though I often find the definitions of both elusive.

My free time is spent reading, writing and enjoying the time I have with friends and family.
