  • Oxford Professor: Cycling is 10 times more important than electric cars for reaching net-zero cities

    Jump

  • The emission savings from replacing all those internal combustion engines with zero-carbon alternatives will **not **feed in **fast enough **to make the necessary difference in the time we can spare: the next five years. Tackling the climate and air pollution crises requires curbing all motorised transport, particularly private cars, as quickly as possible. Focusing solely on electric vehicles is slowing down the race to zero emissions.

    Ah thank god we still have 5 years. Now the climate scientists just need to advise the general public to start shooting all the cars through the motorblock because it has been scientifically proven that is the one way we'll make it.

  • No? Sorry rather clueless about the practical aspects of that. But for electrical why is it not viable to just have channels you can push cables through? Do you mean because of corners?

    Generally I was only thinking of simpler structures though like tiny houses or 1-2 room bungalows so it shouldn't be too complex wiring or plumbing.

  • Hmm very interesting info, thanks. Research about biases and poisoning is very important, but why would you assume this can't be overcome in the future? Training advanced AI models specifically to understand the reasons behind biases and be able to filter or mark them.

    So my hope is that it IS technically possible to develop an AI model that can both reason better and analyze news sources, journalists, their affiliations, their motivation and historical actions, and can be tested or audited against bias (in the simplest case a kind of litmus test). And to use that instead of something like google and integrated in the browser (like firefox) to inform users about the propaganda around topics and in articles. I don't see anything that precludes this possibility or this goal.

    The other thing is that we can't expect a top down approach to work, but the tools need to be "democratic". And an advanced, open source, somewhat audited AI model against bias and manipulation could be run locally on your own solar powered PC. I don't know how much it costs to take something like deepseek and train a new model on updated datasets, but it can't be astronomical. It only takes at least one somewhat trustworthy project to do this. That is a much more a bottom up approach.

    Those who have and seek power have no interest in limiting misinformation. The response to the misinformation by Trump and MAGA seems to have led to more pressure on media conglomerates to be in lockstep and censor anything that is dissent (the propaganda model). So expecting those in power to make that a priority is futile. Those who only seek power are statistically more likely to achieve it, and they will and are using AI against us already.

    Of course I don't have all the answers, and my argument could be put stupidely as "The only thing that can stop a bad AI with a gun is a good AI with a gun". But I see "democratizing" AI as a crucial step.

  • You are arguing there is a possibility it will go that way, while I was talking about a possibility of a more advanced AI that is open source, has verifiable arguments with sources. While the negative outcome is very important, you're practically dog-piling me to suppress a possible positive outcome.

    RIGHT NOW even without AI the vast majority of people are simply unable to perceive reality on certain important topics. Because of propaganda, polarization, profit seeking through clickbait, and other effects. You can't trust, and you can't verify because you ain't got the time.

    My argument is that a more advanced and open source AI could provide reliable information because it has the capability to filter and analyze a vast ocean of data.

    My argument is that this potential capability might be crucial to escape the current (non AI) misinformation epidemic. What you are arguing is not an argument against what I'm arguing.

  • Electric skateboards are like the most compact form factor you can get, but 25kmh / 15mph max would be enough. Unfortunately they are not legal at all in my country.

  • UK creating ‘murder prediction’ tool to identify people most likely to kill

    Jump

  • As a tool to help find patters and collate police reports and notes this could be very useful. We've recently seen how the police dropped the investigation of Russel Brand, while a TV documentary found the truth. I'm betting there are tons of cases like this. Software tools (including LLMs) can scan large amounts of text. And there might be lots of cases that will be obvious once you look at all the pieces.

  • Personally I'm more interested in foam printing, which allows large scale plastic printing of insulated structures. For single story bungalows that should be just fine and transport of the building materials easy. Something like (recycled) PET foam printing should be possible. The printer would be more lightweight than concrete printing too. You could 3D print a clean circumference with PET filament first and then fill in with PET foam. Or you could have tool changing and mill down the irregular foam. And you can recycle the whole 3D print later too.

  • This comes a bit down to utilitarianism vs ethics based on principles. But that's a lie, it's really about who has power.

    I'm just watching a video by Majority Report where he talks about the question "Why is democracy is good" which the Democrats sort of fucked up in the election. And he makes a pretty painful point that it's a "show me, don't tell me" question. If you live in a democracy and constantly exploited, overworked, fucked over, in terror of economic hardship or terror attacks, harassed by police, then what is the point? What is the benefit? I'm not making the point that democracy is bad, but that a shell of a democracy, a fake, is leading especially the "dirtbag left" to adopt a pretty hostile posture.

    So what is the actual quality of life in China vs the USA? What are the actual material benefits looking at living in an apartment, working, raising children and living a peaceful life?

    How do YOU know that life in China isn't actually better and people more happy than in the USA? I don't believe that is true but it's a valid question. Of course China has massive problems and corruption and abuses. But there are a billion people there that were on a medieval level after WWII. The CCP has massively invested in e.g. education and healthcare and infrastructure.

    Or compare quality of life in China vs democratic India. Similar can be said about Iran, 55% of University graduates were women. But it's painted as black and white.

    Sure you have freedom of speech with the means of communication owned and controlled by the oligarchs. And you can say whatever you want on reddit and get downvoted to hell - which goes to my previous point, that the propaganda is so internalized and polarized now that you don't need threats of state violence to keep the population in check.

    So those opinions are not just for fun. The rich get richer and the poor get poorer is an aphorism that is leading the west inevitably towards fascism. So all the "posturing" about how superior our principles and freedums are is just... well it's a delusion. It's happening right now. They are stealing your future right now and there is nothing you can do because they control the media.

    But still the socialists are completely rejected and banned from the largest lemmy instances.

  • How much microplastic is generated during mountain biking?

    Jump

  • Oh wow thanks that is super interesting!

    I have been wondering if you could do something like that with carbon fiber (using carbon fiber as springs) after once seeing a bicycle wheel with spokes that was made using carbon fiber wrapping. Which is a process that can be / has to be automated. If you could create the entire wheel including the tire through carbon fiber wrapping it could become really cheap and worth the downsides. This could be done by a machine that isn't much more complex than a 3D printer, plus a special 3D printed mandrel to build this tire on. Basically they just seem to be large loops the size of the tire that provide the springiness plus a mesh that holds it together with a rubber tread on top.

    PS: Not sure if that "superelastic shape memory alloy" is fundamentally different from normal springs or if that is just marketing speak, or the need to function without maintenance or replacement in space.

    PPS: Apparently it is vastly different from my idea.

    These shape memory alloys are capable of undergoing significant reversible strain (up to 10%), enabling the tire to withstand an order of magnitude more deformation than other non-pneumatic tires before undergoing permanent deformation. Commonly used elastic-plastic materials (e.g. spring steels, composites, etc.) can only be subjected to strains on the order of ~ 0.3-0.5% before yielding.

  • The problem is that over the last decade any nuanced opinions on those topics has become less and less "politically correct". And that is the correct term, anyone who isn't politically correct and in line with the liberal mainstream opinion (= imperialist propaganda by the US state department and think tanks) must by definition by a paid shills of Putin, China or Trump. There are those people of course, but the dynamic has become more and more polarized and steeped in conspiratorial thinking. And that is by "design". It's profitable and it serves the US imperial agenda and it's easier to avoids the frustration of talking to trolls and fascists - just paint everyone of a different opinion with the same brush.

    I mean you can't even talk about talking about it, like not seeing those people as anything but "assholes". The range of allowable opinions has drastically narrowed. It's not even liberal in the modern sense of the word. People are too scared to be liberal any more.

  • You must live in a alternative reality that you think that wasn't a joke! Or you just pretend to not know that was a joke to argue in bad faith and insult me. This is the real Trump derangement syndrome right here.

  • The actual left wing, the something socialists something are partly on hexbear.org and lemmygrad.ml. And they are called tankies and blocked on lemmy.world. So how left wing can most people here be? The thing is that "left" has become synonymous with (neo)liberal values. Like there doesn't have to be a free, independent press or social media and them being owned by capitalists is just fine.

  • I recently thought about what I'm missing, and came up with something rather complicated (sorry, nothing simple haha)

    Basically I'm often compiling information in markdown text files. But images are still web hosted. Sometimes I use spreadsheets and wish I could do simple additions in markdown tables. Or I use bookmarks, but know websites will go down and wish I could just "backup" any website in a compact file and organize it without mucking around with files. Zotero does this partly. I also use "SingleFile" to save websites but it would be nice if it was something semi-compatible to web-archive. Or maybe just save a stripped down version of an article like you see in "reader view" on Firefox. And of course usable in both desktop and mobile.

    I do think Project Jupyter does something like this and there are also other note taking apps.

    Overall the state of computer science in 2025 is still deplorable. The very basics of storing data still don't have good solutions.

  • We're in a post truth world where most web searches about important topics give you bullshit answers. But LLMs have read basically all the articles already and has at least the potential make deductions and associations about it - like this belongs to "propaganda network 4335". Or "the source of this claim is someone who has engaged in deception before". Something like a complex fact check machine.

    This is sci-fi currently because it's an ocean wide but can't think deeply or analyze well, but if you press GPT about something it can give you different "perspectives". The next generations might become more useful in this in filtering out fake propaganda. So you might get answers that are sourced and referenced and which can also reference or dispute wrong answers / talking points and their motivation. And possibly what emotional manipulation and logical fallacies they use to deceive you.
