  • The perplexing part of this for me is charging laptops. Inverters are wildly inefficient but I’m not sure of a way to sufficiently charge (or power) a laptop without one. What are some solutions here?

    What you want is called a downconverter. It will accept a wide range of inputs e.g. 22-40V and will output the voltage you need. Example. I am powering a small computer from a 48V e-bike battery with one of those. (Well not that one exactly as they do not accept up to 48V, but the same type of thing)

    Check on your laptop power supply what output voltage it has. 19V is common but there are 12V ones as well. You will need to solder a fitting connector. Some can be bought, but more often than not, they cost the same as a second hand supply.



  • I don’t see how being critical and optimistic about tech is mutually exclusive. And tech is solving some of our issues and will solve more in the future. Not all of them, but to me being tech-positive and understanding technologies can be sustainable is at the core of solarpunk.

    About longtermism, ok, I did had that definition of the term. But to me solarpunk is not about being delusional about the climate crisis but still being optimistic about the horizon past it.



  • This map was made by French so it may have a bias there. But I know there is a very active lowtech community here in France. As a techno-utopian I spent a long time ignoring them until someone told me that the raspberry pi is lowtech and that I am doing lowtech robotics (wth?) . Here it basically seems to be a synonym for open hardware, with an emphasis on community rather than projects. It is actually pretty chill.




  • Oh I don’t want to be confrontational at all! I am just trying to understand what I am missing, as usually I am nitpicky with perspective too but could not spot the mistake there! Please dont see that as a very serious or angry argument!

    I am not assuming a ship, but a cave, so from a point of view of low altitude. I imagine the camera being horizontal, at the level of the tallest person’s head. I see 3 layers on the background: the canyon wall on the right, fairly close, the small ridge with what looks like a nice ski slope on it and a big mountain in the background. Granted, that one is huge, you may need a 1500 or 2000m differential between the window and the background mountain top but I think I could find such spots on Google Earth in the Alps or the Himalayas.







  • That’s really interesting! It shows which communities share users. I am part of jlai.lu, a french-speaking community that is relatively isolated by also slrpnk.net that seems very spread out!

    Would it make sense to compute the standard deviation of each instance’s communities? It would give an idea of which are islands and which are more extended. Not sure if it makes sense to compute it more on 2 dimensions or on the original 21934 though.








  • Pirated many things when I was student. When I started earning a living I realized that the amount they ask for is really not excessive so started paying for several media, but they keep insisting on making sure that what you pay has less usage value than what you pirate. Stopped buying CD when one was designed to not play on my computer. Stopped paying for movies since they decide to tell you where and when you are supposed to watch them.

    I gladly pay for books (which half of the time I then pirate to read on my eReader) and video games but the other digital media are trying to establish a toxic relationship and I’ll have none of it.
