• 🔗 Why did renewables become so cheap so fast?

    by
    Fossil fuels dominate the global power supply because until very recently electricity from fossil fuels was the cheapest. This has changed dramatically. In most places power from new renewables is now cheaper than new fossil fuels.
    Fascinating read.

  • 🔗 The Revenge of the Hot Water Bottle

    Imagine a personal heating system that works indoors as well as outdoors, can be taken anywhere, requires little energy, and is independent of any infrastructure. It exists – and is hundreds of years old.
    Reminds me I should use my yutanpo more. But truth be told, Sophie always sleeps by me feet, so I already have a Sophie-tanpo.

  • TIL: How to change the Docker ENTRYPOINT with Packer

    by
    I've been working on automating setup and deployment for Tanzawa. This necessitates setting up a python 3 with all of the requisite dependencies and then starting a webserver.

    Initially I tried to set the run_command, but that's executed when you build the image, not when you run the image. The command used when running the image is controlled by the ENTRYPOINT, which is Docker specific.

    You can change your ENTRYPOINT by adding it to the "changes" section of your Docker configuration in your packer .pkr.hcl configuration file.

    source "docker" "ubuntu" {
  image  = "python:3"
  commit = true
  changes = [
    "ENTRYPOINT [\"uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data\"]"
  ]
}

  • 🔗 How we changed our roof and cut 1.5 tons of CO2e.

    by
    Since Oct 01, 2021 we have saved 2,300 kwh, equivalent to 720 kg CO2e (assuming a 0.3g of CO2e per Kwh of heating gas). At current trend, we would save 5,200 kwh, equivalent to 1,600 kg CO2e until Apr 15, 2022. To put that number in perspective, a French emits about 9,000 kg of CO2e per year. Not bad for a roof.
    Fascinating how much easier we can cut with upgrades to the house that reduce carbon and improve comfort. Beautiful roof, too.
