Have a rod that pivots in its center and has objects of equal mass at each end, like a balanced seesaw. But make one of the objects very low density (less than water) and other high density.
Since the densities differ, water will cause the rod to rotate. But since the masses are the same, bumps will create no net torque around the pivot point and thus no rotation.

F------(x)------C
(x): pivot point
F: float
C: counterbalance
Also include a small spring to keep the float in the down position.
I'm sure there are other ways like sensing the electrical resistance of the water.
Or just let the float sensor bounce. It's underwater when it stops bouncing and is continuously in the up position.
I surrender my speedometer ceremony for the wade sensor. Instead of a motor sweeping the speedometer from 0 to 200 on startup, put the motor to sweep the wade sensor.
Waymos are fleet vehicles. Recalls go to the owners, just like with other fleet vehicles such as rental cars, taxis, limos, delivery services, utilities, and city/state/federal government. It doesn't really matter who is whose customer.
The article mentions this: "A few years back, Linux added a way for software to wait on several events at once, which is something Windows had built in for decades, but Linux didn't."
Here's a better comparison to pro athletes. Their work output is winning games. How do they get good at (and stay good at) that? Is it by playing real games for points?
That's a part of it, but only a small part. They don't get good at the thing mainly by doing the thing. They get good at it by training to do the thing.
An NFL football player does a ton of things other than playing in games. They have practice scrimmages. They do drills like throwing, catching, running patterns, tackling, reading quarterbacks, stripping balls, picking up fumbles, etc. They work with coaches on their technique. They watch film. They spend many hours in the gym and on the track building their strength, speed, cardio, and stamina.
Yes, it's true that your software skills will atrophy if you don't use them. But that doesn't mean your skills have to get worse and worse causing you to eventually quit the job. It means you need to set aside time to maintain your skills. It may no longer happen automatically as a side effect of your work, but it can happen intentionally instead.
The scenario is a cross-country trip in an electric car. What actual, specific advantage does a train or bus offer in this scenario? What problem does it solve better?
It's an electric car, so carbon emissions are low.
Most of the route will be in rural areas in the middle of the night, so the impact on traffic will be minimal.
As for the cost to build and maintain the roads, they are already needed so rural areas are accessible. Wear and tear on roads and bridges isn't much of an issue since heavy vehicles like trucks cause massively disproportionate damage[1]. (A bus might actually be worse than the equivalent number of cars in this respect.)
Apparently a common source of problems is taking two different medications without realizing they both contain acetaminophen.
Suppose your arthritis is acting up, so you start taking Tylenol 8hr Arthritis Pain[1]. That's 2 tablets every 8 hours. They're extended-release with 650mg per tablet. A total of 3900 mg in 24 hours.
A few days later you get the flu, so you decide to add what seems like a completely different medication: Theraflu Flu Relief Max Strength[2]. It has a cough suppressant and an antihistamine. But each caplet also contains 500 mg of acetaminophen. It says to take 2 caplets every 6 hours, so you take 8 of them in 24 hours[3]. That's another 4000 mg.
Between the two, you're at 7900 mg.
Then you wake up in the morning and take both medications, but 30 minutes later you've forgotten you took them. You're not thinking straight because you're sick. So you accidentally take a second dose. That additional 2300 mg brings your total to 10200 mg.
[3] You weren't supposed to take 8 of them, though. If you'd read the label very carefully, you'd have seen it also says not to exceed 6 in a 24-hour period.
My personal rule is to only purchase over-the-counter meds with a single active ingredient. I'd rather separately take an antihistamine, expectorant and painkiller than a concoction where I have to read the whole label and do math while sick to separate the doses and timings.
There are some that are very hard to find as a single ingredient. Recently I was purchasing a medication for back pain, I had a choice as to which other ingredient I wanted, but I didn't have the choice of none. I picked the combined ingredient I don't like to take, because I wouldn't be adding it on top.
I did toss on the other option, stand alone, at one point so I could get some sleep.
It left the medication I was more comfortable taking as an add-on option if things got bad enough. (This particular medication has much lower risk of overdose, so if I got stupid and took it again there would be no significant additional risk.)
It's ironic, but taking the combined medication with a known higher risk of its own was better than taking the lower risk medication.
One was controlled, higher risk, taken at specific times, while the other was taken in addition, on demand, as required.
Specifically this is one reason they’ll sell you cocodemol or Vicodin but not codeine or hydrocodone directly — if you take enough to get a codeine high, you’ll have taken a toxic amount of paracetamol/acetaminophen, so they assume you won’t.
A fission power plant simulator lets you have fun playing through a meltdown disaster scenario. A fusion power plant simulator is "worse" because it takes away the "fun" of meltdowns. The humor is in reacting to the simulator as if it were a game (some are, but this one isn't).
I probably could have worded it better but while I understand the process and the inherent safety vs fission, I am no expert in the nuclear field. I suppose what I should have asked is what are the risks of e.g retrofitting a fusion reactor into an existing Con Edison facility in the middle of Manhattn, e.g. the historic IRT Powerhouse on 59th st.
