I had thought/heard that Polestar was a subsidiariy of some trashy junk dealer out of the dark pits of the CCP.
Volvo was bought by Geely, which is a Chinese brand. So you weren't entirely wrong. However, Geely seems to be giving Volvo a great deal of autonomy.
FAA needs to pull something really drastic on Boeing for this fustercluck that they call the MAX fleet of planes. Ground them all and force them to go through FAA certification, then make any design corrections (at Boeing's cost) to every existing MAX before it's deemed airworthy again.
Apparently you didn't read or comprehend the headline, and neither did the mods. The FAA is concerned with the manufacturing of these planes. That's what "conformed to approved design" means. This door failure appears to be completely unrelated to the design changes made to accommodate the LEAP engine on the MAX.
Design quality means jack shit if you cant manufacture to the design requirements.
The "defeat device" isn't a physical thing that plugs in somewhere, it's in the software of the ECU.
Exactly. Engine manufacturers don't get in trouble for failing emissions tests. They get in trouble for undocumented code.
I've yet to find an article that mentions how this code works. Detecting a vehicle is being tested is a blatant violation. However, any undocumented code that might impact emissions is considered a violation of the Clean Air Act.
That is lawyer language for we did it but were not admitting anything that could get us sued by our customers.
No. I've worked in the automotive software space previously. The articles I've read don't mention anything specific. They only mention a secret "auxiliary emission control device". That's a legal term for a software function that might impact emissions.
In automotive software, there is wiggle room for what you can and cannot do in your software. One thing you absolutely cannot do, is have poor documentation. How many software engineers do you know that write good documentation?
Cummins statement that no one acted in bad faith could very well be true. Someone likely forgot to document a function in the logic, and the EPA discovered it. Whether is was intentional or not, undocumented code is considered a "defeat device" and Cummins is now in deep trouble.
There was a lot of evidence that Volkswagen vehicles were creating measurable emissions above the legal limit before the discovery of the undisclosed software. I haven't seen evidence of measurable emissions violations in this case, only evidence of undocumented software. If someone has a link showing otherwise, I'd like to read it.
2) The two pharmacists did not "figure out" phenylephrine does not work. What they did is the effort to raise the previously known facts (known to the literature) to the FDA.
Right after they moved pseudoephedrine behind the counter there were grumblings that phenylephrine didn't work. It just took 18 years for the FDA to take the complaints seriously.
Intelligence is knowing that a tomato is a fruit. Wisdom is knowing that you don't put tomatoes in a fruit salad.
Don't get me started! There are nutritional classifications, culinary classifications, and botanical classifications.
Nutritionally, potatoes are a grain, and so is corn.
This tells us something about ChatGPT - it can't be based on neural nets or genetic algorithms because those are intrinsically incapable of preserving data.
No, preserving training data is a known issue in neural networks. It's called overfitting. High order polynomial regression suffers from the same issue.
Second, ChatGPT developers don't understand their own code. Otherwise they'd fix the bug rather than simply TOS it out of view.
Another common issue with neural networks. Nobody knows what's going on inside them.
All seems condemned in the long run to approximate a state akin to Gaussian noise. -- James Martin
