  • What I want from a mobile provider in 2024

    I’m dashing this post as a follow up to this thread on Mastodon, when I was asking for pointers for new providers, after getting sick of Vodafone’s poor broadband service. It’s an outline of my circumstances as I hunt around for an alternative provider of mobile connectivity for someone who lives in Berlin. Here are…

  • If you want greener energy, what’s the best way to get it?

    If you want greener energy, what’s the best way to get it?

    I saw an interesting chart fly by recently from a tweet by Juliaen Jomaux, taken from the recent IEA Renewables report (page 57), What does this chart tell us? The key thing that attracted my attention was how in China, the use of fixed-tariffs / premiums, where anyone building a renewables project gets a fixed…

  • TIL: Keeping your hair when upgrading Django 3.2 behind a Caddy server

    This is a quick note to my future self, on how I recently got Caddy and Django to play nicely after an upgrade from Django 3.2 to a something newer, like 5.0. The problem After updating to Django 4.0, every request that sent data like a POST (the kind you use to login) was no…

  • Notes on the Deutschland ticket

    I recently got round to subscribing to the Deutschland-ticket in Germany, and it got me thinking a lot about mobility in the wider sense. I’ve dashed out some thoughts now to come back to later.

  • What gets to be called green online?

    I work at the Green Web Foundation, and part of my job is maintaining a platform to help people find providers of green digital hosted services. I was asked about whether recent changes in the law might impact what gets called a green hosted service there. I’ve shared my thoughts here because a) LinkedIn has…

  • Why we should be intentional about the mental models we use for thinking when we think about digital sustainability

    To make sense of our world, we often form incomplete, yet still useful mental models of how it works. Most of the time these are helpful, but when we are dealing with complex systems, what might feel intuitively right, can lead to outcomes totally at odds with we were initially aiming to achieve. This post…

  • Hydrogen datacentres – is this legit?

    Part of my job at work is to stay up to date about the options for decarbonisation of the digital sector. I listened to a podcast yestersday where there were a load of claims that seemed well.. too good to be true, even with my developing knowledge of the sector. I’ll outline them below, because…

  • How much power do hyperscalers use, and how much would it cost to go fossil-free 24 / 7 ?

    I found out today that the Carbon Disclosure Project allows you to register and download their questionnaire responses. This means for companies that conveniently leave absolute energy usage figures out of their annual reporting, it’s possible to get an idea of what they might be – something I care about in the context of figuring…

  • A new Californian law on offsets goes a long way to making them more transparent

    This came up on one of my feeds recently. Emphasis is mine from the original text on the Californian legislation website detailing the bill: AB 1305, Gabriel. Voluntary carbon market disclosures. This bill would require a business entity that is marketing or selling voluntary carbon offsets, as defined, within the state to disclose on the…

  • Listening notes: zero carbon cement on the Volts podcast

    I listen to quite a few podcasts, and as an experiment in Jan 2024, I’m going to try to share the notes from ones that stand out for me. This is partly as a way to retain what I learn, and share with others, but get better at writing quickly. The first one is an…
