I didn't say they don't need calibration.
I said they don't need calibration all the time.
Failure to connect to the cloud should not result in immediate device failure. Manual calibration steps should be possible. Or at least a message "cloud service unavailable, device will stop working in 48h" or similar.
I don't understand why people are willing to bootlick the company in this case. Cloud connected everything is cancer.
I mean, the data is easily googleable.
Me: Prison is not the answer to everything.
You: It is because (insert specific scenario).
Let me introduce you to the word "everything" and what it means.
This whole article is about how to STOP people from driving while drunk. I'm not hand wringing, I just don't think that prison is the only solution here.
Because prison is not the answer to everything for fuck's sake.
Sure, in this case we can say "fuck you" to drunk drivers and the don't deserve sympathy, but this everything must be cloud connected trend is going to fuck us all eventually.
The problem is that the above sentence requires a person to be able to hold two thoughts in their head at the same time, which appears to be above almost everyone commenting in this thread.
Drinking and driving is not cool.
Making a device that could and should operate locally rely on a cloud service is also not cool. Breathalyzers have been around for decades, and do not need calibration all the time.

That's some optimism you have, asking people to think before posting.
I hate all of this sales pressure BS - that the instant anyone hears your name you have to try to "convert" them to sales - and I literally run a webstore.
It's all so deeply anti-consumer, and I want no part in it.
Firstly, I see you have this notion that martian rocks must all be igneous.
You're not talking about rock, you're talking about regolith.
Depending on where the regolith is sourced
Regolith is not "sourced", it's blown across the whole planet. It's not simply "whatever the underlying strata is made out of".
But, since we are playing 'name the ignorance' in this exchange, your attestation stat perchlorate is 0.5% liberatable oxygen says 'Say i'm ignorant of basic chemistry without saying i'm ignorant of basic chemistry, and am bad at reading too.' The 0.5% statistic comes from the publication at bottom, and is the proportion of the regolith that is perchlorates.
I am the one who mentioned that regolith is 0.5% perchlorates, not that "perchlorates are 0.5% oxygen". *facepalm*
"Saying we'll get oxygen from the 0,5-1% of a poison in martian regolith, rather than bulk ice or CO2, is..."
For God's sake, learn to fucking read.
Washing the regolith to remove the perchlorate is a requirement for *any* other use of that regolith
Which is why you shouldn't be celebrating its existence. It is a problematic contaminant, not a resource.
As you have rightly pointed out, the water ice on mars is more 'frozen mud'. Cleaning the melt is going to be a necessary first step to using it *regardless*. That means either vacuum distillation, thermal distillation, or reverse osmosis filtration. Again, NOT OPTIONAL. This is necessary equipment that you need to bring, regardless.
And this just to get water, the most basic of offworld resources. And all of that equipment (especially the mining hardware itself) requires maintenance and spare parts, which impose more dependencies. And the TRL for use on Mars is low regardless.
You've gone from talking up the ease of operating on Mars to talking it down, yet your self-righteousness hasn't shifted at all in the process.
RO filtration is the least energy intensive of these.
Except, it isn't. 0,5-1% perchlorates. RO typically removes 90-95% of perchlorates. So you're down to ~500ppm. Human safety levels** are in the low parts per billion. You're five orders of magnitude off. Yes, you can purify water that far - and the more perchlorates, the easier - but you're talking an over millionfold reduction. It is not at all trivial. You're talking first RO to get it down to levels where it won't hinder bacterial growth, then bioreactor bacterial remediation, then filtration, then RO, then ion exchange. This is not some little, simple system.
** Plants can tolerate much more perchlorates than humans, but they also bioaccumulate perchlorates of exposed to them, so you have to reduce the water to low ppb levels.
The end products are clean water and perchlorate contaminated mud, and clean mud, with contaminated water.
Viola! *eyeroll*
And your "plan" for dealing with waste perchlorate doesn't just magically produce pure O2 and NaCl in the real world. First off, molten sodium perchlorate, which is what it becomes before it decomposes, is an extremely corrosive oxidizer. Exactly what are you planning to make the furnace out of, platinum? Secondly, you never get perfect decomposition. Apart from residual perchlorates, you have residual sodium chlorate, which is also corrosive, and is a literal herbicide. And your gas stream will contain contaminant chloride and chlorine dioxide, which, news flash, you don't want to breathe.
There is no way on Earth anyone would ever prefer this to just conducting electrolysis on the water that you've already purified.
The Tao is like a glob pattern: used but never used up. It is like the extern void: filled with infinite possibilities.
