  • The software subscription fee was an ongoing cost to whoever installed the equipment, now that fee has been replaced by a per-use fee that’s part of what drivers pay. It’s easier for businesses to justify installing chargers if they know that it’s a one-time purchase with no ongoing subscriptions, fees, or management hassles.

    Off topic: how much would it cost to run a charger continuously?

    Depends where you are and how much electricity costs there. Could also depend on time-of-day if electricity metering in that area has time-of-use rates. The biggest level 2 chargers put out 19kw, where I live it would cost about $60 per day to run one of those chargers at absolute maximum. Realistically speaking it would be hard to run one full-time though, since the average EV has ~80kw of battery and would be full after 4-ish hours.

    Is it exploitation? I’d argue slave or prison labor is exploitation because the workers have no freedom of choice. Bees are free to leave, and the queen will in fact do so if not content with the conditions in the hive. If the queen leaves, all of the bees will swarm with her and you’d be left with an empty box.

    Beekeeping strikes me more as symbiosis. The beekeeper provides ideal conditions, far better than the average location that would be found in the wild, and can help protect the hive against threats like mites. In exchange the beekeeper receives a share of the honey produced by the hive.

    No beekeeper takes all of the honey from the hive. Only the top box (the “honey super”) of a typical hive stack is harvested. A grate below the top box (a “queen excluder”) prevents the queen from entering it so no larva are laid in the top box. The workers bee are smaller and can pass through the grate to build out comb and produce honey. The comb and honey in the bottom boxes are left to the hive to feed its workers and produce the next generation of bees, ensuring the survival of the hive.

    A queen excluder cannot be used to prevent swarming long-term as the drones that gather the pollen also won’t for through the grate! An excluder might be used to delay swarming and buy time so the beekeeper can offer another solution, like adding more boxes to the hive or splitting it into two hives. Better beekeepers proactively manage their hives, e.g. by setting up an empty hive in advance to essentially offer a swarming hive a new ideal home whenever they’re ready for it.








  • Is there any benefit at all

    Maybe! There’s at least some scientific evidence that chemical compounds in mushrooms can have medicinal effects.

    Bias disclaimer: I put a lion’s mane mushroom tincture in my morning tea because it may have a neuroprotective effect (source). My father’s father had dementia, my father is currently in a home with profound dementia, the chances it’s going to happen to me are very high. It’ll be years before I know whether lion’s mane mushroom will do anything for me (and even then you couldn’t claim anything from one data point), but I’m willing to try anything as long as it’s affordable and has at least some plausible evidence behind it. This isn’t the only thing I’m doing of course, I’ve also overhauled my diet (MIND diet) and lost 30 pounds (obesity is correlated with dementia).

    why can’t you make it your self by pulverizing dried mushrooms of the same variety they use into powder and making the coffee yourself?

    You absolutely could. Or, you know, just eat some of the same mushrooms. The benefit to dried products like Ryze, or tinctures like the one I use, are that they’re convenient, easily transportable and self-stable. I’ve cooked up fresh lion’s mane mushrooms several times, but not super often because they’re not in many stores in my area and tend to be pricey for the amount you get. I’ve also grown my own from a kit but that takes significant time and a little bit of daily attention to maintain optimal growing conditions. The tincture is convenient and relatively affordable as far as daily supplements go.



  • OpenAI on that enshittification speedrun any% no-glitch!

    Honestly though, they’re skipping right past the “be good to users to get them to lock in” step. They can’t even use the platform capitalism playbook because it costs too much to run AI platforms. Shit is egregiously expensive and doesn’t deliver sufficient return to justify the cost. At this point I’m ~80% certain that AI is going to be a dead tech fad by the end of this decade because the economics just don’t work now that the free money era has ended.


  • Tl;Dr the protocol requires there to be trusted token providers that issue the tokens. Who do you suppose are the trusted providers in the Google and Apple implementations? Google and Apple respectively, of course. Maybe eventually there would be some other large incumbents that these implementers choose to bless with token granting right. By its nature the protocol centralizes power on the web, which would disadvantage startups and smaller players.




  • One of my grandfathers used to work for Nortel. One of the projects he worked on was the Trans Canada Microwave, which was a microwave relay system built in the '50s to carry television and telephone signals across Canada. The towers were installed all over Canada in remote locations and high elevations. Maintenance on the system could be required even when the weather was bad. My grandfather told me that the engineers who worked on the towers would sometimes stick their hands in front of the microwave emitters to warm them up. It’s anecdotal, but I’m relatively confident that it’s theoretically possible to warm people with microwaves.

    Big caveat, though. Those engineers knew how powerful the emitters were, they knew that microwaves are not ionizing radiation and thus posed no cancer risk, they knew roughly what percentage of their hands was composed of water, and thus how much heat energy their hands would absorb from the emitters at a given power level. That’s the only reason they were willing to do it, well that and they were probably the kind of people who got a kick out of doing something that would appear insane to most of the populace.

    It seems very unlikely to me that a microwave system could be turned into a safe people-heating system for at least the following reasons:

    • Feedback loops. All modern HVAC works on feedback loops. Your thermostat detects that the temperate is cold, it fires up your furnace / heat pump / electric baseboard / whatever and produces more heat. When the thermostat detects that the temperature has reached the set-point, it shuts off the heat. Current thermostats would not be able to detect the effect of microwave heating, which prevent the establishment of a feedback control loop.
    • Uneven heating. Things with more water will heat up a lot faster than things with little water. This is usually fine when microwaving food since most of our food is water, in varying concentrations. If you’re heating up a burger in the microwave, you can put the patty in by itself for a minute, then put the bun in for 15 seconds, then reassemble a burger that doesn’t have a cold patty or a stiff overcooked bun. If you’re heating up a person, you can’t ask them to take out their almost-entirely-water eyeballs to ensure they don’t overheat.
    • Failure conditions. If your heat gets stuck in the on setting, the maximum result is probably that your house will get sweltering hot but not hot enough to kill you in a moderate timeframe. Depending on power levels, a microwave heating system could internally cook people in their sleep if it entered a failure mode where the heating got stuck in the on setting.
    • Efficiency. It takes a considerable amount of power to run even a small microwave, and that’s blasting microwaves into a relatively tiny cubic area. Trying to heat people would require microwaving a much larger volume, and said volume would also be moving around. Trying to emit microwaves in even a house-sized volume would probably be prohibitively costly.
    • Interactions with metal and other objects. Microwaves can create intense electrical fields around metal objects, and those can become intense enough to create plasma and electrical arcs. Hell, you can create plasma in your microwave with two grapes. Blasting microwaves into a large volume with unknown contents would be a great way to create an unexpected fire.

  • Not the person who made the comment, but here’s my understanding. A “third place” is somewhere you spend a lot of time when you’re not at home (the first place) or school/work (the second place). Third places such as community centers were vital to the civil rights movement in the 60s, it was where much of the movement’s meeting, debating and organizing took place.

    The Reagan administration systematically defunded any of these politically active third places that were receiving federal funds, probably because they were worried that they’d be infiltrated by those scary communists. They were so worried about what the organized people might do in the future that they did everything they could to kick the financial struts out from under these community organizations. In many cases this destroyed some or all of the local community benefits that those organizations were actually providing.

    This trend cut across the political spectrum too. The Clinton administration did its own wave of defunding, though I suspect that was more for economic (i.e. neoliberal) than political ideology. Combine the lack of community investment with the rise of the internet, and you arrive at the situation we have today where third places are becoming increasingly scarce. It’s hard for communities to develop and maintain a cohesive identity when there’s no longer any metaphorical “town squares” where the people in that community gather.
