In almost every system with failsafes there will be conditions that can bypass them. The goal is not to make it impossible for the unsafe condition to happen, but to make it so that in the expected uses the failure will not happen.
In this case it's a domestic microwave and the mainboard is housed inside the electronics enclosure, so covering the whole mainboard in salt water is not an expected occurrence in a domestic kitchen.
But there are ~1 billion microwaves in the world... I'm sure it has happened somewhere. As a designer of a billion-sold device, your job is to make sure that the expected number of people harmed by your device is substantially less than one, which gets really hard when all the risks are multiplied by 1e9.
Your job is to make sure the number of people harmed _while using the device as intended in a reasonable situation_ is as close to 0 as possible.
A domestic microwave is for use only on land, indoors, in a domestic kitchen, and in an unmodified form. In these conditions there is no conceivable way that salt water could saturate the main board, or bypass all the interlocks in another way.
Yes there are ways that all the safety systems can be bypassed, but not while a reasonable person is using the device as intended.

Source? People take risk in their day to day life and should expect to take risk. Why would they expect their microwave to be completely free of risk?
At the moment in every jurisdiction I’m aware of the driver is always considered as “in charge” of the vehicle no matter what assistance functions are being used. It’s the driver’s responsibility to avoid collisions in all cases.
If you have a collision and your vehicle is judged at fault by whatever authority does it in your area the you are liable.
Mercedes Drive Pilot (“SAE Level 3”) is certified on some very specific stretches of insterstate in California to not require the driver to be responsible.
that's really dumb of Mercedes take on that liability for little benefit - sell more cars, make more profit? My prediction is MB drops this or goes bankrupt in the next 10 years.
It's a marketing gimmick. The conditions under which it can be used are so restrictive that it's really not useful which means it will be rarely used so Mercedes exposure to liability is really quite small.
Not sure you understand how "The Formula" works. The profit generated by adding this feature will outweigh the cost of any resulting accidents that they take liability for.
A less pessimistic way of phrasing it is that within the boundaries they've defined, their self driving system is so much better than a human that they're willing to assume responsibility for crashes deemed "at-fault" while using the system.
Not intentionally trying to compare that with other automakers, but Mercedes is the only "you can buy now" vehicle (ignoring robotaxis/Waymo/others) that assumes liability with those capabilities. Until other automakers provide that legal guarantee, they're parlor tricks at best that will continue to get folks killed in scenarios that they otherwise wouldn't had they been actually paying attention.
"Your honor, I don't know how to explain this to you any more simply. I wasn't driving, there was a brick on the gas pedal. It's not my responsibility, not my fault!"
Well that will depend on your local laws, but to my knowledge except for certain authorised pilot programs all cars on the road must have a driver.
Where I live if you are in the driver’s seat no matter if you were actually actively driving you are considered to be the driver. This has been well established here in drink-driving cases, but you’d have to ask a lawyer for your area.
On modern macOS applications can flag an input field as secure, which blocks keypress interception. The permission is fairly new, but the actual feature has always been there as part of the window server. I used it back in the 10.4 days to implement macro recording.
Classic Mac OS extensions on the other hand had free rein to modify any part of the kernel. They really could modify anything.
Don't most people already have a plug in their garage? All mine certainly have. There's no need to get full EVSE for most people, a 2.4kW outlet as found almost everywhere outside North America will easily handle daily driving needs for anyone who's not in a travelling job.
Also if everyone in your neighbourhood turning on a space heater strains the grid you have bigger problems.
Utilities have plenty of ways to solve that. We already have electric water heaters on demand controlled circuits and electricity billing that incentivises off-peak use.
And as for range? 400km is plenty for all but one trip a year, if that's an issue for your use perhaps EVs are not for you.
I have no garage and work from home. So no workplace to charge.
So now you’ve added another thing I have to worry about - finding charging somewhere along my 10 minute errand route?
EVs are a bad solution to a problem I don’t have. Hybrids are much better.
For the small amount of driving I do, driving my commuter ICE car with a tiny, 35-mpg 4 cylinder engine is fine… why are the EV cultists so convinced their way is the only way and the rest of us are living in prehistoric times?
Plus, your EV is heavier than my ICE, so your tires shed rubber particulate more quickly than my tires due to the weight, which is also an environmental pollutant (that is toxic enough to kill wildlife, btw)
>> I have no garage and work from home. So no workplace to charge.

Your car lives somewhere when you're not doing errands. Expect a charging point there as demand for that grows.
Not to mention charging points at the mall, shops, restaurants and so on.
Clearly it will be a long time before EV replaces ICE completely. There was lots of horse infrastructure which changed when cars appeared.
But the pendulum is swinging and each motion there opens up new opportunities.
Also each motion has an impact on existing infrastructure. Expect gas stations to be less common, ditto for mechanics and so on.
>EV's produce 38% less tire & brake dust than ICE vehicles.
>non-exhaust emissions on an ICE vehicle are roughly 1/3 brake dust, 1/3 tire dust and 1/3 road dust. EV's have almost no impact on road dust, 83% lest brake dust and 20% more tire dust.
> though much of this is attributable to a vehicle mix that is more focused on larger vehicles, as it seems like every EV manufacturer is making huge SUVs and few are making small cars
My point exactly. Your new EV has more tire dust (and probably more brake dust) than my old, smaller ICE.
No. It's really easy to install charging points on office parking space and supermarket. You don't need to plug at home when half of the day the car is parked at places with chargers.
Not half a day, but BEVs are impractical today if you don’t have home charging, but throw in restaurants, movie theaters, doctor’s and dentist’s offices, and L2 charging starts to become a practical alternative for many.
In the short run. When I replaced my minivan with a PHEV my gas bill went down $200/month, my electric bill went up $30. Chargers where people park is a long term investment in lower costs for everyone. Hopefully chargers are everywhere in the future so we don't need the ICE at all. (I just bought a EV, I've barely had it a week and already have run out of battery - I was just able to reach a charger, but it required changing my route since there were none along the route I wanted)
No? I haven't seen a "peak oil" article or prediction in at least ten years. It would be GREAT to reduce our dependence, to make them cleaner, to make them more efficient, and to increase the use of renewables. But who is saying we have to "stop" oil and gas?
I was being a bit facetious, but I guess when either they're fortunate to live extremely close to a charger, or they have one in building, but then it seems like they'd be fighting for parking and charging space, which doesn't seem to me to compete favorably in terms of practicality. Or the housing market finally crashes and there's a viable path out of renting for those that want to do so.
When L2 errand charging becomes enough that they can keep up with daily travel by plugging in where they go and park for a while - restaurants,
movie theaters, retail stores, doctor and dentist offices, etc.
Probably not 7 days a week, but a couple days a week, sure.
And of course not everyone. Maybe 10%?
Not that it matters. What do I care about the needs of some Texans? (I mean that non perjorativly). I mean just because ranchers still need horses doesn't mean the rest of us have to use them.
The world will go EV, even much of the US will go EV, regardless of what some folks need.
Almost nobody is driving 200 miles to get to work. Almost everybody will move if their commute is more than half an hour - this is through out history and includes hunter gathers deciding to move the tribe, peasants walking to their field... There are a few people driving that far in the US, but either they are planning to move soon, or they don't expect the job to last long.
There are a lot of people driving more than 200 miles a day for work though. Many of them are in cars because their unique skills are why they need to be there (as opposed to delivery drivers who are bringing cargo).
There are also people who drive a long distance once a week. I know of a rural hospital that pays a lot of doctors to drive in on Thursday so locals don't have to go to the city. (they keep an ER, but the rest of the hospital is empty other than a few nurses the rest of the week)
I just try to buy natural or the semi-synthetic cellulose fabrics, there's quite a variety.
Natural fabrics are cotton, silk, wool and linen of course, but the semi-synthetic fabrics like the rayons (viscose, modal, "bamboo", Tencel, Lyocell, Bemberg, and some sorts of artificial silk) are wood cellulose chemically rearranged so they're just cellulose when they reach you.
The fabric referred to as Acetate is cellulose acetate, so not pure cellulose like cotton and rayon but is just as biodegradable and contains no petroleum plastics.
Of course the production process for viscose rayons (not Tencel/Lyocell/Modal - those use a different process) isn't great. It uses carbon disulfide which is a neurotoxin. However it's not a persistent pollutant. Modern factories in the west try to capture and recycle as much carbon disulfide as possible (it's released from the rayon during processing and can be fed back in to the process) but as a lot of factories are in countries with poor controls on this it's hard to tell how many are doing this.
ive recently found some rayon shirts I really like, but how do you wash them without destroying them? everything I've read online says dry cleaning is the only way
For viscose most rayon a gentle cycle in a front loading washing machine is generally fine, though the more silk-like variants are less resilient. You might want to put it in a garment washing bag to make sure it doesn't get stretched while wet. If you don't have that it's dry-clean only.
Varieties like modal and Lyocell are machine washable.
As accurate as our knowledge of genetics, which is not very outside of the identified set of pathological genes associated with hereditary disorders.
Your genome is very complex and we don’t have a model of how every gene interacts with every other and how they’re affected by your environment. Geneticists are working on it, but it’s not here yet.
And remember that 23andMe, Ancestry, and most other services only sequence around 1% of your genome.
Part of genetics is pattern matching, and last time I checked I still can't find a model that can correctly solve hard Sudokus (well, assuming you don't pick a coding model that writes a Sudoku solver.. maybe some of them are trying to do genetics by doing correct algorithms), a trivial job if you write a program that is designed to do it.
As a consumer I used to use it all the time, though it matters a lot less these days. Two A4 pages at 50% zoom (A5) fit on one A4. You could cut your printing cost for drafts in half by doing that, back when we had to actually print to check the layout. Same went for posters etc, and since the aspect ratio was preserved it was really handy to preview at home on A4 sheet before taking it to the print shop.
I’m sure you can do that on other size systems, but ISO paper sizing gives you accurate scaling.
Same goes for photocopies, photocopiers can scale copies so two A4 sheets copy to one, if you don’t need the same size.
This assumes there are no errors anywhere in the sizes or alignments of the A4 base page or either A5. Otherwise, you'll have an A5 running over an edge of the A4 or both A5s overlapping in the middle.
If your pages are designed with margins on the assumption that errors in the paper are common, this issue disappears because the margins cover for it. But still, if I wanted to do a display of two 8.5" x 11" sheets of paper, I'd want a board that was bigger than 17" x 11".
Sizing errors are essentially unheard of, and I've never seen anyone having any trouble with joining or folding ISO paper to go one size up/down. It's a completely normal operation, which people working in printing and publishing will routinely do without a second thought.
For commercial printing, there's the SRA paper series (Supplementary Raw) which is designed to accommodate bleed and alignment bars. An A4 glossy magazine, for example, might be printed on SRA3 and will be trimmed, folded, and stapled automatically at the end of the printing process. But that's a technical detail for the printer to care about - the publisher or designer might specify "folded A3 with bleeds", and the printer will choose the correct raw format to provide that within their printing system.
As the other commenter said, alignment issues have never been a problem.
If you're manually aligning the sheets on the photocopier bed maybe, but the edges are set up for that so it's never been an issue for me. However every photocopier I've used that was made since the late 90s lets you do the sheets individually so you can use the copier bed to align each one.
Because the ability to scale like this is so ubiquitous we're just all used to doing it.
I had the reverse, we had to get a ream of US Letter and corresponding envelopes sent over so we could ensure the layouts printed properly. Also some chequ… “checks” which were fascinating.
In this case it's a domestic microwave and the mainboard is housed inside the electronics enclosure, so covering the whole mainboard in salt water is not an expected occurrence in a domestic kitchen.
