    Are happy hours and lunch specials not dynamic pricing? It’s just a different way of framing it as a discount rather than surge price, but it’s basically the same idea as far as I’m concerned. I’m happy to vote with my wallet on this, if Wendy’s decides they want dynamic prices then I’ll just go elsewhere. Fast food certainly isn’t an essential.



  • I have a North face shuttle daypack that is exactly the nominal dimensions and conveniently boxy. I’m 90% sure it’s fake though, so going with a ruler to a store or market that sells backpacks is what I’d recommend.

    There is a company making a hard sided suitcase with removable wheels which can fit. I’d strongly recommend against that because the handle will take up so much of the already limited space. And there’s nowhere to put the wheels when they’re removed where it can still fit. Note that Spirit sizers are unofficially 18x14x9 rather than the officially advertised 18x14x8. Frontier’s bag sizers are truly 18x14x8.






  • To a lot of these voters it’s not about having a logical cabinet nor even policy. It’s the individual as a character representing our nation, and to them Trump is better spoken than Biden even if what most of he says has little basis in reality.

    This is why Obama had such a good time with swing voters, it’s not really about the policies from what I see. I’m shocked no party since 2008 has tried running a younger candidate. I’d love to see someone younger debate Trump. Like Pete Buttigieg for example. Like ya he’s still a career politician, but I suspect he’d do much better at making the insane stuff Trump says sound insane.


  • The problem is that this isn’t really even trickle charging. Customers would absolutely complain and say it’s not working because it couldn’t charge the battery more than 1-2% in an entire day of sun. EV batteries are 60kWh+ yet getting more than 2kWh/sq meter daily from residential panels is hard for much of the US. Add to that the:

    • weight of panels
    • cost of panels
    • heat trapped in the car from having a roof literally designed to absorb solar radiation
    • fragility of panels (although all these glass roof EVs have that problem already) And it’s really not worthwhile.

    One solution to the apartment street parking problem is adding charging ports to streetlights (they do this in Europe). But for most of US apartments there’s already dedicated parking space so also space for chargers. The unruly size of new vehicles is a much bigger problem in my mind, if there were actual motivation to fix this problem in government it would already be solved through some tax credits.





  • It’s still not a lot of energy though. Some rough napkin math for how far this would get you is below:

    Typical medium size cargo ships in the Panama Canal travel around 25 knots burning 63000 gallons per day of fuel with 5000TEU of cargo. That’s roughly 600mi/63000gal or 1142miles per ton gallon. That Silverado EV somehow weighs 4 tons (totally safe to be driving at highway speeds), so this is the equivalent of roughly 285.5mpg per Silverado. The Silverado is 67mpge on its own, so the ship is just over 4x as efficient (and slower which is ignored here but would impact the vehicle efficiency).

    So using the Silverado’s 450 mile optimal range we can say it has at most an optimistic 7 gallons equivalent fuel in its 200kWh battery. 50 MWH would be enough for a theoretical 1750 gallons equivalent if efficiency were the same. But for the efficiency difference this corresponds to a 4.2x improvement to 7350 gallons equivalent. Therefore this is enough to run that typical ship above for 2.8 hours. So with 65000 tons of cargo in the above ship to do a 200 mile route this ship would need roughly 3x as large a battery. More likely it will just carry ~1/3 the cargo or have charging stops en-route.

    The 19.4km/h top speed of this ship suggests they’re well aware of the extremely limited range this will have for its size and it sounds like the Shanghai to Nanjing route will be pushing it’s limits despite being less than 200 miles.



  • To be fair to Netflix before other networks took streaming seriously they were charging very little to license their content on Netflix. That’s why it had everything and was so good to be better than piracy. The royalties from Netflix couldn’t be enough to fund these networks. Even Netflix themselves as the studio has struggled substantially promoting these price hikes and the effective recreation of cable TV.

    As they lose more of the licensed content they’re forced to focus on their own. Unfortunately for the just part they can’t compete with constant new mediocre shows and movies. The streaming industry as a whole has lost sight of what made it popular in the first place.



  • Ya I used to always tip cash but stopped all food delivery entirely ~5yr ago. By turning food delivery into a live auction everybody loses except the company running the service. Drivers compete against eachother accepting the absolute lowest fees while customers need to play the game of choosing an appropriate tip for a prompt delivery while also ideally not shorting the employee who ultimately accepts the order. But since to accept the order they need to compete with other drivers it’s naturally going to lead to them accepting lower prices, allowing the delivery company to pocket the difference. Not a good system.
