If likes and boosts are overrated, then is there a way to find others' posts about a topic or to get more replies to my posts?

If only voters would get this worked up about corruption.

People are also ignoring the benefits. Data centers don't bring a lot of jobs after construction is complete, but they can generate a lot of tax revenues for counties and cities. Huge amounts of money that can be a real game-changer for the local budgets, and could be very beneficial for the locals. By itself that's not a reason to accept them, but it should be part of the overall calculation, and the net cost/benefit of the projects should be reasonably and fairly evaluated, and negotiated.

But this isn't what's happening.

The thumb wheels on the steering wheel do that. You do have to use the touch screen to put it in "mirror adjust" mode, but really that's something you only do once. Set up your driver profile, set your mirrors, then the car just always changes them to your settings.

I find the auto wiper works pretty well... it is important to keep the windshield fairly clean, but I like to do that anyway.

Yeah, the Model 3/Y handles are weird. The S/X handles are pretty nice. In theory the fact that they're motorized could make them a maintenance problem. In practice, little electric motors are extremely reliable. There was a problem with the wiring harness getting fatigued and breaking about 10 years ago, but that's been fixed.

Those are also on the thumb wheels on the steering wheel.

Before I came up with my current system I spent a lot of time looking into actuators for windows. They exist but they're expensive, often bulky and look like a lot of work to install and maintain. Then it occurred to me that I already have a whole-house fan (HVAC system)... if I could just get it to draw from outside rather than from the air returns. That part woks great and I think it does give me a pretty good single point of control. The only problem is that the house is pretty tight so I also needed a way to create some negative pressure, hence the laundry room to attic fan. I think that's still my airflow bottleneck.

As for whether I've crunched the numbers.... no, I haven't. And since I installed solar last year it maybe doesn't even matter any more? Throughout most of the summer I'm actually giving away nearly a MWh per month of electricity even after running house, A/C, car, steam shower, etc. So it's really more of a game to me than a serious attempt to save money. That said, I do watch my energy consumption closely (game, right?) and running the fans consumes maybe 400W. Overnight that's about 3.2 kWh. Meanwhile, my AC draws 4 kW, so if my AC kicks on for 45 minutes it consumes as much as the passive system does all night. And for that, the passive system cools the house by ~10F degrees while the AC will cool it by about 2F, which would indicate 5X efficiency improvement. But even that doesn't fully capture it, because the AC will cool the *air* by 2F while the passive system will cool the house and also much of the thermal mass, so it's actually moving quite a bit more heat out than the thermostat temperatures would indicate.

So, yeah, an order of magnitude more efficient seems about right. When outside air cools down at night!

I've also been thinking about building something for my shop. It's an uninsulated pole barn (30' wide x 40' long x 25' high) which gets quite hot in the summer and quite cold in the winter. I think some automated fans to exploit day/night temperature variations could probably move the average interior temperature several degrees closer to comfortable, year round. Even better if I insulate it.

That is not what they found. What they found is that if you spend 60 minutes doing the homework with AI, you learn approximately as much as someone who spends 60 minutes doing it without AI. If you spend 20 minutes doing it with AI, you learn as much as someone who spends 20 minutes doing it without AI. Etc. The only real difference is that the AI people get way better homework scores, and as a result, tend to stop spending as much time, and thus tend to learn less.

That's what this preprint study found.

100% this. Even a short 5-minute quiz with just a couple questions at the start of each day will do the trick. But you simply can't rely on homework scores to be a proxy of learning or time spent studying anymore. Brief daily quizzes on the previous day's material will force them to.

Also, It's not like students have the excuse of, "I couldn't study, I didn't have anyone to explain X to me" anymore. The very AI that they might otherwise use to cheat on their homework can also explain to them the things they missed in last year's algebra class that are blocking them from learning this year's calculus, or whatnot. Congrats - you now have an infinitely patient personal tutor who will spend hours dumbing things down for you until you get it. Now you have no excuse - learn the material. It becomes all about actually putting the time in.

Yeah. There's been widespread misrepresentation of this (preprint!) in the media. What they actually found: test scores correspond to how much time you spend doing homework, regardless of whether you use AI or not. Which should not be a surprising result! Of course, the AI people, esp. those who had been using AI for more than a few months, stopped spending much time on their homework, and then their test scores fell to match the non-AI users who didn't spend much time in their homework either.

The TL/DR is, in today's age, you cannot use test scores as a proxy of how much time a user is studying or knows the material.

There are of course some caveats, beyond the fact that it's just a preprint - notably that there's nothing to separate why the user started using AI to do their homework, so there's potential confounders in there. For example, if a student is in a poor family, maybe they had to get a job to help pay the bills. But working a job itself can lower test scores - for example, having to work late the night before an exam. So there are some confounder problems with the study. That said, I'm sure the general conclusion is correct: time spent doing the thing = amount of learning the thing (relatively independent of what tools you're using in the process).

Oh and one more thing. Walmart could pull a "Winco Foods" and not accept Credit Card payments at all. In my area there's a Winco Foods about 30 miles from where I live. They only take debit cards, not credit cards. They do beat Walmart's prices so whenever I'm nearby, I take advantage of that.

Yes they could, but they'd lose out on a lot of money. Winco foods likely saw their average receipt size and realized most of their patrons could either do debit or cash. Being a grocery store, cash is likely a viable option if you're not doing big shopping trips and spending $20-40 a trip, and more for debit.

Walmart however does sell more expensive stuff that most people will not have cash for which can be expensive. Think video game consoles, TVs, etc. Limiting yourself to debit and cast would make those transactions very annoying.

It's why Costco always retains a credit card option - because they know cash and debit only get you so far. (And because debit protections are worse, I refuse to use debit, so it'll be cash only).

With global warming, those ice roads may not be around for much longer.

The high price is due to the obsession with SUVs, and people feeling they "need" one, just for that one time in 20 years they may need the extra cargo capacity. Give me a sedan with a hatchback any day.

There's a reason I call Buick vehicles, "ick", and that is one of them.

Honda and Toyota aren't great when it comes to the user interface. Hyundai does a much better job on that front. Ford isn't horrible about their systems from what I saw the last time I rented a vehicle, but Hyundai is definitely better.

The cost of RAM has been going up and up and up. $200 worth of RAM from January of 2025 is now up into the $600+ range for the same RAM if you buy it today. In the next year, it might end up over $1000 because AI is destroying the computer industry.

Once you go to a display for your instrument cluster, you get away from the, "what the hell is that weird light that just popped on in my instrument cluster?!?" problem, because the display can TELL you what is wrong in a way that static indicator lights can not. For Apple Car Play or Android Auto, you get navigation from your phone, so you don't need to dig out a map to figure out where you are, or how to get somewhere, and it's right THERE, so you can actually focus on driving. Heads up displays are also getting more common, so you don't need to look DOWN to see what you want/need to see(something that not all car makers do well, but does help keep you focused on the road).
