  • I’m frankly rather concerned about the idea of crowdsourcing or voting on “reliability”, because - let’s be honest here - Lemmy’s population can have highly skewed perspectives on what constitutes “accurate”, “unbiased”, or “reliable” reporting of events. I’m concerned that opening this to influence by users’ preconceived notions would result in a reinforced echo chamber, where only sources which already agree with their perspectives are listed as “accurate”. It’d effectively turning this into a bias bot rather than a bias fact checking bot.

    Aggregating from a number of rigorous, widely-accepted, and outside sources would seem to be a more suitable solution, although I can’t comment on how much programming it would take to produce an aggregate result. Perhaps just briefly listing results from a number of fact checkers?



    • Economic points are limited to plans gestures about taxes. Nothing about tackling corporate-induced inflation / shrinkflation.

    • Nothing about supporting workers’ rights and aiding labor organizations.

    • Nothing about building a stronger regulatory framework and tackling loophole use by corporations and ultrawealthy.

    • Nothing here on continuing to support US allies and build international partnerships.

    I recognize none of these are exactly keystone domestic culture war issues, and also all more or less reflect where she stood on Biden’s major pushes. But I’m still disappointed these all go unmentioned.




  • Like the other comment says, concrete is rocks of various sizes (called “aggregate”) mixed with a cement and other additives to change its particular properties.

    The cement is the really important point, because once water is added to the cement, it undergoes a chemical reaction which hardens it. Saying cement “dries” isn’t quite correct - yes, it stops being wet, but some of the water actually ends up incorporated into the molecules of the final cement. This is also why cement is really hard to recycle - you have to undo that chemical reaction, as opposed to asphalt which stays the same material.

    Fun fact: When concrete is mixed at a big plant, it begins curing immediately. Concrete being carried in those big mixer trucks needs to be delivered before it cures in the truck!



  • Specifically talking about asphalt vs. concrete:

    • Asphalt is relatively cheap vs. concrete. This is partly because asphalt is a whole lot easier to recycle than concrete, which is almost un-recyclable, but also because asphalt is a relatively “simple” material - it’s mostly petroleum byproducts and gravel.

    • Concrete doesn’t grip very well, compared to the relatively textured surface of asphalt. Especially when wet! This is why you often see concrete formed with “ridges” or “bumps” cast into it. However…

    • This also makes concrete noisier and bumpier to drive over, making drivers less happy. It’s why it’s often used for short, low-speed uses like driveways, parking lots, or side streets.

    Just about the only thing concrete has going for it is it’s endurance, which it definitely wins handily.

    Every few years another engineered road solution is conceived - I’ve seen variations that would use glass which could be ‘re-fused’, concepts for recycling plastic waste, and many more. Most of these run into the issue that they’re either less ‘grippy’, or that they simply cost more even accounting for the longer lifespan.
