Nice! Some of my favorite shows lately have been French (Ad Vitam, Lupin, Zone Blanche) and German (Berlin Station, Counterpart, Dark).

I can definitely get behind this kind of regulation, as long as the content percentages are sane. It would break down pretty badly if the EU required 30%, Brazil required 30%, India required 30%, China required 30% ...

Of note: SharePlay isn't sharing a video stream. It is synchronizing playback in a separate application instance on each device. That means each device must be able to use the application on its own. In most cases, that means every person watching must have their own subscription to the service involved.

If the generator is off, it isn't generating any CO.

Not creating any once it’s off, sure, but it creates a lot more than you might expect until the engine and exhaust path are up to operating temperature. Run a cold engine for just a few minutes, and it can easily make enough CO to kill you several times over. It also accumulates in the blood for quite a while, so even once ambient concentration drops to normally-tolerable levels, that can still be enough to push somebody already exposed past the point of unconsciousness.

The risks involved in running a generator (any internal combustion engine, really) are pretty manageable, but they’re really, really dangerous if you don’t know to manage them.

Bayer... as in Bayer filter.  An RGB pattern filter over the camera's sensor.  One color filter per pixel... Red, Green, or Blue.  The image colour data is captured and interpolated for the neighbouring pixels to produce a full colour image.  Virtually all commercial colour sensors employ a Bayer filter solution otherwise you would require three sensors to be used... one per colour.  Not easily implemented in such compact environments as a beam splitting prism would be required too.  Creator of the Bayer filter.... Bryce Bayer... who worked with Eastman Kodak.  Died in 2012 I believe. 

Sure, but the Bayer pattern is naturally a tiled series of squares with two green, one red, one blue photosite per four pixels. Lines up nicely with Pentile display subpixel arrangements. So what in the world is "Quad Bayer"?

Did a little research, and it turns out it's a Sony variant of the normal Bayer pattern. They turn each photosite into four separate, smaller photosites, then average their values as a way of reducing amplification noise. Thus, the "50 megapixels" is a lie. It has 50 million photosites, but they operate in clusters of four, producing one output pixel value which is still only one channel. It's the equivalent of a 12.5 megapixel sensor.

Still no idea what Octa PD is supposed to be.

Can't the sensor output at full 'resolution'?

Pixel binning to lower megapixel counts is common nowadays but I thought the option was still there to output without pixel binning. 

Yes, you are right. The sensor can output at full resolution as well.

Ish. You can get a file out of it with 50 million pixels, but the resolving power is physically limited to about 13 megapixels even in that mode. Setting aside diffraction for the moment, due to how the same-color photosites are clustered (dense, then a gap, then dense, then a gap), they could never capture contrast data in the different channels to provide 50 megapixel level sharpness.

But in reality, we can't set diffraction aside. With an f/1.85 lens at smartphone lens distances, the Airy disk diameter is 2.37µm or larger. The pixels on that sensor are 1.2µm, so any given Airy disk covers four of them. They physically can't resolve separate detail.

Which is actually a good thing, as if they could resolve separate data, you would need a more serious antialiasing filter to make sure they couldn't. The main advantage of Quad Bayer sensors seems to be that they don't need as much optical antialiasing to avoid horrible Moiré.

No sub-pixels on sensors... just one photosite per pixel.  Pixels are grouped under one of the color filters.  This pixel grouping is a form of "binning" which effectively combines groups of pixels together to produce a "super pixel", effectively increasing the photon count and reducing noise as a result.  A good short article at https://www.gsmarena.com/quad_bayer_sensors_explained-news-37459.php explains this decently.

Yes, which is why my only mention of subpixels was immediately preceded by the words "Pentile display". 

For resolving purposes, it's clusters of four photosites which all share the same color. This means you only get 6.2 megapixels of green detail, 3.1 of red, and 3.1 of blue. Very misleading to call it a 50 megapixel camera.
