  • VW is good at making cars, but bad at software. They’ve had to delay the introduction of new models (Golf, ID.3) because of software issues. Rivian has sort of the opposite problem: their production lines sit still often because of problems in the supply chain.

    Volkswagen has the expertise to solve Rivian’s production and supplier problems, and the cash they will need to survive and develop some cheaper models (the EV market is stagnating right now for a lack of budget options, and Rivian only sells trucks and SUVs). And they’re hoping Rivian software engineers can help them fix their software woes.


  • Pretty much the perfect form factor in my opinion. Put the back seat down when you need to transport cargo, up for people. Really practical. If you want to do camping trips or road trips where you need to move four people with cargo, you can get one with a towing hook.

    The one thing it’s not great at in my experience is transporting babies around. There’s just not quite enough space for the car seat, stroller, two parents and assorted diapers and stuff. We can make it work, but it’s quite uncomfortable.




  • Honestly, I think it may be possible to build entire roads with enough crushed metal elements in the asphalt/concrete and a slight low power charge throughout the entire surface would be able to keep any vehicle battery at a steady charge.

    You might be underestimating how much power a car consumes while driving. For example, a Tesla model 3 has an efficiency of about 130 Wh/km in mild weather at highway speeds. Assuming that on the highway you’ll travel 100 km/h, that means you’ll use 130*100 = 13.000 Wh/h, a constant power draw of 13kW. That’s enough to power perhaps 8-12 houses on average.

    A km of road could have, let’s say, 200 cars on it (4 lanes, 20m per car). That means you’d need to pump about 2.6 megawatts of power into every kilometer of road to keep them all topped up.

    EDIT: fucked up math









  • The numbers are different because the site doesn’t naively count every line but merges some as a single package. For example, at the very top of the Debian list we have 0ad, 0ad-data, 0ad-data-common. These are all counted as one single “package.”

    One might argue that doing the comparison in that way is more useful to an average user asking “which distribution has more software available.”








  • Before they went public, who was foolish enough to invest in a company that has never turned a profit?

    You’d be surprised. The basic strategy of losing money hand over fist for years to grow yourself to as large a user base as possible, before finally aggressively monetizing that user base, is well established in silicon valley. Investors would not even raise an eyebrow at the loss numbers posted by Reddit because of how exceedingly common that is.

    And it has worked several times, making some people ridiculously wealthy. Good examples are Amazon, Facebook, and Uber. So usually companies on this level have raised hundreds of millions to sometimes billions of dollars in investment capital, allowing them to operate at these levels of losses for years at a time.
