    In a selected port, with a crane. That’s basically the tl;dr from the video Kalash posted at 4:23 time index.

    But the Houthis didn’t fire at warships. I know some outlets had similar sounding titles but they were clickbait and their own articles were contradicting their title. The Houthis were firing towards merchant vessels and within 20 km or so, there was also a warship, which then reacted.




  • Especially living in a city, this looks interesting to me. ‘Fast’ charging I’ve seen was in the range 30-60 min but then it’s like the phone, from about 20% up to 80%. So living in a city, I’d have to wait for half an hour for half the battery.

    With a swap-station, it could be nearly as fast as a fossil fuel stop. About 2 minutes for a 0% to 100% stop.

    This also allows for smaller batteries, for smaller cars, for lighter cars. You don’t need to carry a lot of overall range if you can swap/refill to 100% in 2 minutes.



  • I’m a layman when it comes to solar installations, but I read a bit into the topic, as I want an installation on my balcony next year.

    I read that partial shadows on the panels are the worst due to the connection in series of the individual plates. There are rows or even loops connected on a panel and with a part of that connected series covered in shadow, it results in a fraction of the power output. A tiny shadow results in a huge loss.

    If that is your garden, you should fix that to avoid shadows onto each other.


  • I think there are also different mentalities. Just last winter, I had a similar discussion, where someone explained to me that the room heating is meant to fully offset the temperature, so he can walk summer and winter in shorts, t-shirt and barefoot. So it’s 23°C in winter.

    While I’m used to wearing jogging pants and socks indoor during winter, so 18°C is fine for me.

    Then again, you also have to adjust for personal preferences, different sex, different heating infrastructure etc. But 23°C to go shorts and barefoot in winter was an extreme reveal to me, that people do something like this as well.



  • media literacy will be woven into existing classes and lessons

    It’s surprising to me, that the USA/California only now decides to include that into school lessons. I thought that’s a common thing around the world.

    Already 20 years ago in school, I remember we had media literacy by analysing and comparing newspapers. We got a selection of papers that the teacher bought and we had to check for design, formatting, letter size, pictures, categories, order, article size and content, factual reporting etc. Just full on analysis for teens to understand different styles in writing, reporting, publishing. Even comparing the same articles, written by different newspapers and how things can be expressed differently giving different impressions but originating from the same event.

    Is that not common during school in Europe / around the world for decades?




  • The natural gas through the pipelines is not owned by the transit or endpoint country. Same with Nord Stream, Germany is used as distribution hub in central Europe. E.g. after Poland closed their pipeline to Russia, their natural gas supply from Russia was simply transferred via Nord Stream and Germany, from the other side across the border into Poland.

    And even with natural gas that stays in German storages, it’s not owned by Germany. It’s owned by private companies that sell it during winter to the highest bidder. German gas storage can supply other countries that have high demand and smaller storage capacities in a cold winter.

    So regarding the resource replacement, it depends on the country that uses the natural gas at the end.

    Looking at natural gas in Germany, the usage for electricity generation is relatively low (~7-12% over the last 5 years). It’s more often used by the industry and for it’s chemical properties, as well as heating in homes. You cannot just replace that with coal or nuclear ovens. But overall there is a plan to increase the capacity for electricity generation over the next few years as backup for the coal phaseout during low renewable generation. The new gas plants are intended for natural gas and later hydrogen.



  • It’s disappointing that they only exclude the information use regarding ads.

    So they will still track everything users do and profile them, just like any other free user. And they can sell to everyone else who pays for user data (e.g. AI learning, market research etc.). With that wording, they could even sell to ad companies, if they e.g. use the data for some algorithm optimisation in their tech department. So they leave the door open to keep selling the data to 3rd parties, while already charging the user ‘starting at’ 12.99€.






  • I feel the very specific community topic split is already affecting Lemmy negatively. So I think having larger, broader community topics (e.g. ‘commuting’ instead of a community for every single option to commute by itself), with more diverse content, interaction and of course more visible activity, would also attract new users.

    Right now some communities are so specific, that by its creation, it’s a filter bubble by design. And then of course you don’t get a lot of content or interaction, as only yea-sayer get accepted.

    Interaction requires different approaches, opinions, options and of course people who upvote them even when disagreeing. The reply box is the correct option when disagreeing, not the downvote. That’s how Lemmy will sprout.

    tl;dr Broader community topics for larger, more diverse and more active communities
