  • This is directly a result of Elon’s edict that Tesla cars don’t use lidar. If you aren’t aware Elon set that as a requirement at the beginning of Tesla’s self driving project because he didn’t want to spend the money on lidar for all Tesla cars.

    His “first principles” logic is that humans don’t use lidar therefore self driving should be able to be accomplished without (expensive) enhanced vision tools. While this statement has some modicum of truth, it’s obviously going to trade off safely in situations where vision is compromised. Think fog or sunlight shining in your cameras / eyes or a person running across the street at night wearing all black. There are obvious scenarios where lidar is a massive safety advantage, but Elon made a decision for $$ to not have that. This sounds like a direct and obvious outcome of that edict.






  • My first reaction was how stupid this is. Dirt, debris and other things will get on the panels and cause lots of problems, but after a few minutes I realized it’s actually quite brilliant.

    There are three major costs of solar, the panels, the location, and the wiring + inverters. If the tracks are used as the wires (extremely low resistance paths back to an inverter), the location is wasted space so basically free, and the inverter can be placed anywhere along the path to remove the power from the tracks, the cost of this comes down to mainly the cost of the panel, which is actually pretty cheep these days.

    The real challenges will be in cleaning & maintenance, vandalism, and modifying the track to limit the conductive paths (assuming they’re used for this).



  • This isn’t what they want to happen. They know it will happen, but this isn’t the goal or objective.

    Amazon is a big boy company, if they want to cut staff, they’ll cut staff. The problem with cutting staff this way, is that they don’t get to decide who they’re cutting. They don’t want to cut talented employees at random, they want to pick the low performers and let them go. This is kind of the opposite of that.

    The higher skilled the employee is, the more likely they are to have been hired remote, and to feel they can find another job also. That means they’re effectively shooting themselves in the foot and getting rid of some of their talented employees for the benefit of bringing people into the office.

    There has been a swing in the business opinion that work from home isn’t as efficient. This is basically the higher-ups falling in line with that opinion.


  • Technology has moved from nitch nerdy thing to general public usage and as it did so it became usable without knowing what’s going on. Gen Z doesn’t know shit about technology, they just know how to use it.

    When I was a kid, if you wanted to get a computer working you had to screw with the RAM settings or build the computer yourself from components. If you didn’t know how to do this you talked with someone who did. I’ve forced my kids to learn at least some of this, but the idea that they’re more tech savvy is ridiculous. They’re users of tech, but it’s become too complicated (and more user friendly), so they don’t know what’s happening behind their screen.





  • Hilary lost because she sucked major ass. I didn’t vote in 2016 because fuck political dynasties, and the DNC did everything it could to prevent Bernie from getting the nomination, which unfortunately worked. Being less young and stupid, I probably would have voted for her if I were in 2016 again. I would have hated it though, just as I would have hated voting for Biden but would have done so. I’m not particularly excited about Kamala but she’s definitely a lot more palatable with SO much more appeal than Hillary or Biden had.

    The stupid thing was that they didn’t need to do their dirty tricks. The things like what DWS in Arizona were well after Bernie was mathematically out of the running. I’m a Bernie fan and I voted for him in the primaries in California, but he lost on Super Tuesday (well before CA and AZ voted). He failed to capture the votes and was not really in contention.

    I think Hilary lost for three reasons. 1. Republicans had their smear machine running on her for over a decade. Propaganda works. 2. Her public speaking persona was bad. I heard her speak in a more normal conversation and she sounded smart, articulate, and hitting all the right points. I was impressed. But her speech giving persona was bad and came across as snobbish. 3. Sexism. It’s not THE reason she lost, but I think there was and is a vein of that running through America. “What if it’s her time of the month and she has her finger on the big red button?” “Blood coming out of her whatever”, etc.

    I think time has proven out that she would have been a 10x better president than Trump. Just like Gore would have been 10x better than Bush. So much less death, so much better policy. If they’d been elected, the world would be a different place today. (Stupid undemocratic electoral college system)
