  • These people got caught because someone found their car and thus license plate.

    Another had left a fingerprinted bottle that went missing when watching surveillance footage.

    And then were able to confirm after finding the same outfit from the surveillance footage.

    The lessons to be learned are to not use cars anywhere near the scene, leave no trace, fingerprints or digital evidence, including a phone, and make sure any recognizable clothing is well hidden, or even better thoroughly destroyed.

    Oh and don’t post anything on social media.

    As someone who checked it out for physics here’s my experience:

    Anything that could easily be found and be correct that would be found on chegg, would be easily repeated by chatgpt, and with usually clearer solutions that was easier for slightly different problem prompts.

    Anything that could not be well answered by chatgpt likely would not have a good solution on chegg, being either outright wrong, or extremely confusing as an answer.




  • Well let me clarify a bit why I think they are the worst.

    They have the full complexity an an ICE car, with the added difficulties that arise in a full EV

    You need to build and design a car that has all of the downsides of ICE cars. Complicated engine, emissions management, fuel, air intakes.

    With a lot of the downsides of an ev. Large heavy, expensive batteries.

    Meanwhile you get limited upsides. Evs get lower maintenance and transport costs and ICE cars get range.

    Plug in hybrids will have harder maintenance than either, while not getting the fully reduced transport costs as it’s not as efficient as a full ev.

    Here’s where traditional hybrids win out, their battery can be really small, correspondingly cheap and more efficient.

    Lugging all that extra weight around decreases the efficiency of the vehicle, where for full ev that matters a lot.

    When running in full gas mode your lugging around a heavy battery for nothing, and in a full ev mode your lugging around a heavy engine for nothing.

    The High-medium range of full gas would be better served by a traditional hybrid, and the low-medium range would be better served for full evs.

    I’m sure there is a narrow window for plug in hybrids, but again that is going to be rare and shrinking as evs get better.

    While you can’t fix stupid, we do have to think about how a product actually gets used vs it’s design.

    If nobody is plugging their plug in hybrid, then maybe the manufacturer should remind them, even if its only outlet level power.

    To me it is also a symbol of overconsumption. Buying a vehicle that will cover 100% of your use cases vs buying for 99% and renting a more suitable option for that 1%.

    I do think this argument for me would change if manufacturers took a different approach. If they took something like a traditional hybrid, like a Ford fusion, and stuck a modern battery in and added a simple plug would be great. Then increase the efficiency a bit and maybe someone could get 10 miles of battery from a regular outlet.



  • Too be fair, it is not the choice of individual Americans to live in and be dependent on a society that was forced to become car centric and dependent.

    With very few options to travel by car, and the large dominance of single family homes, we don’t get many options.

    Fuck people who drive gas guzzling trucks and giant suvs though. That is just unnecessary. But again car manufacturers have been slowly convincing Americans to purchase larger more expensive suvs for obvious reasons.

    This issue is absolutely a governmental policy choice, and one that is continuing to be upheld.


  • Grid storage wouldn’t be lithium ion, something like lithium phosphate would be better.

    Step one, buy in bulk to get a price closer to $150/kwh

    Step 2, use for much longer than 2000 cycles, lfp have much longer expected lifetimes, and since space/weight aren’t a huger consideration, you can replace individual cells when they go bad.

    Step 3, produce your own energy, if you have your own energy generation, you don’t need to pay grid prices, and profit is much better.

    Disclaimer, I am not an expert in this at all, but this is how I imagine it could make sense.


  • They’ve had fab problems for years, in that it cost them a ton on money and much longer than desired to shrink nodes, so they’ve fallen from a leader in fab production to being behind.

    Not to mention there’s not much money to be made from fabs, unless your tsmc.

    AMD, Qualcomm, Nvidia, Google, Apple, are all huge tech companies that design their own cutting edge chips, and only Samsung is another company that both designs and produces chips.
