You never could. Parents do their kids' homework all the time, or siblings, or friends. Ideally, teachers should give a large pile of optional homework. State right up front that although they will grade it, it will not count towards your final grade, and the grade on each homework paper will be given as a percentage of the problems attempted, not of the total set of problems. So if you do five problems and get them all right, you get 100, and if you do 50 problems and get most of them right, you get 90. At that point, the purpose of homework is primarily to help the students learn, rather than being primarily a way to evaluate the students. Give some participation points for doing some of the homework, but not based on correctness.

This has three benefits. First, the smart kids who understand the material quickly will do just enough to make sure they understand it and then will stop wasting their time, but will still have feedback on the work that they did do. Second, the teachers won't have to grade as much work from students who don't really need that much extra work. Third, no at-home cheating, whether by technology or by other people will distort their grades.

Obviously this doesn't work for everything — essays, for example — but for general homework, it's a big win.

You can certainly do that along with what I suggested, though I'm not sure how much difference it will make in the grand scheme of things.

Agreed.

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.

On the other hand, the fraud losses are a lot lower, and as far as I know the transaction fee is the same, and the credit card company pays the 0.15% fee out of their cut. So while it theoretically *could* eventually drive up the rate in the future, I don't think that's happening currently.

I think that's fair, although it feels like the tone has gotten harsher.

Definitely. I'm actually already seeing a little of that in late August. Nights are getting down to ~62F, which is managing to cool the house to the high 60s. I'm wondering if I could get a higher-volume fan for the laundry room to increase the air flow... I'm sure that by the end of September we'll have nights in the 50s but days will still often reach the mid-80s. That's when another benefit of having it automated kicks in. If I were just opening a bunch of windows before going to bed, there would be a period of time when the house got too cold at night. With the automated system, when the house gets to 62F it turns the fans off.

Of course, as we get into winter, I pop the laundry room fan out and fill the gap with an insulated pillow of the type they sell for filling swamp cooler vents.

Speaking of swamp coolers... those have historically been fairly effective in Utah, thanks to the dry air. My first house had just a swamp cooler and it was honestly fine. I've actually thought that it might make sense to have all three: passive cooling, swamp cooler and central air. With a smart system deciding which to use when. You don't want to use the swamp cooler a lot on days when the A/C might need to run, because it raises interior humidity, which the A/C then spends a lot of effort extracting. Maybe... have to consider the cost of buying and installing the swamp cooler.

Assuming it is installed inside somehow, you can avoid the projectile risk by not using any ferrous metal in its construction. Non-ferrous metals (e.g. dental fillings) aren't a problem in an MRI, though you may feel the electrical eddy currents induced by the magnetic fields. For something like an LCD panel, you'd probably want to shield the ever-living crap out of it to minimize problems, and I'm not even certain that it is feasible for that reason, but that's different from the LCD panel physically flying off the mount.

Don't interpret this as me having an opinion on this specific article (I don't), but that's a gross misrepresentation of what the law requires. As someone running a business, you *do* have a fiduciary duty to the stockholders, but that's not the same thing as requiring you to maximize shareholder value at all costs. Doing what is best for the company and the shareholders does not strictly mean more dollars.

For example, if a company had a choice whether to make a drone that would make a lot of money by selling to militaries, but would be used to annihilate the shareholders, no rational person would claim that the fiduciary duty requires them to build the drone.

More broadly, companies have a responsibility to behave ethically, for two reasons:

• Perceptions of unethical behavior can impact a company's long-term profitability by discouraging customers/users.
• Unethical behavior is often illegal, and when it isn't illegal, it often becomes illegal as soon as a company demonstrates that it is possible.

In other words, behaving unethically is how companies find themselves massively regulated in ways that negatively impact long-term profits. Every antitrust suit is an example of this, as the only reason those laws exist is because some company previously behaved unethically.

It's possible. My prediction is that they're not going to find any evidence of collusion, that all of the DRAM manufacturers simultaneously shifted production to AI chips in response to clear market demand, not because of any agreement.

Yes, there was collusive price fixing 25 years ago, but the companies got slapped pretty hard for it -- not just cash fines but prison sentences for executives. I think that prior experience makes it less likely that they're colluding now, not more likely. Once burned twice shy.

To be fair, back then, 40 was old. But yes, you get my point.

Well, yeah, but those are still cities. Almost twice as many people live in parts of cities that are not "dense urban cores".

And the dense areas involve apartment complexes with hundreds or thousands of units and interior halls, so they're not delivering one package to the building; they're delivering a hundred. It wouldn't make sense to send drones for that.

But if you can handle the suburban sprawl with drones, that's a huge logistics win, because that's where all the time is spent — not by somebody going to an urban-core building and dropping a hundred packages in the mail room, but by somebody going to a hundred individual houses and dropping off a hundred packages one at a time.

One correction: It didn't have anything to do with discovery. Discovery was complete when the judge put the trial on hold to allow the deal to close. What happened was that Musk realized that proceeding with the trial was dumb because he was going to lose and be forced to complete the transaction regardless, and possibly on worse terms than he could get by just doing it. Avoiding the public spectacle of the trial was also a consideration, I'm sure, but not discovery... 10 days before trial discovery is already done.

You're not misreading it. It is individualized. Different cancers express different antigens, and the mRNA vaccine needs to construct something that expresses those same antigens to train the immune system to attack them.

The nice thing about mRNA, is that it is potentially relatively cheap to synthesize mRNA strands and replicate them. It won't be hundreds of dollars, but it won't be millions, either. Right now, I think it's hundreds of thousands per patient, but that will go down over time as they streamline the process of taking a sample of the tumor and determining an mRNA gene sequence that matches said cancer. And economies of scale on the equipment will also probably help.

It may also be the case that it becomes less individualized over time. At some point, we might reach the point where they have a bunch of pre-sequenced antigens that are all ready to go, and someone just keys in a list of antigens, and a piece of software spits out the mRNA sequence. At that point, it is still individualized, but with a much, much more streamlined process for generating it.

Note that I don't work in this field, so take all of this as the opinion of an educated layperson observer. :-)

And by that, you mean X is bad for our democracy because it is a for-profit corporation. Free speech and corporate fiscal sponsorship of that speech have been at odds since time immemorial. The problem is that the corporate sponsorship seems to be winning and the free speech seems to be losing, drowned out by the voices of those who have more money, more bots, etc.
