Somebody doesn’t understand battery technology.

Some of the Android makers would be $h!ting themselves if this goes through.

Apple battery 80% after 500 cycles
Samsung expected to be 70% after 300 cycles.

I had a client with a 2011/2012 15" (non Retina) - her trackpad wasn't clicking so she stuck something thin down the side (effectively stabbing the slightly swelling battery) and there was a fire. It wasn't anything as big as the above one though.

Normally that kind of puncture damage is required to start a lithium battery fire - you need to allow oxygen in. The battery could have had a rare defect that made it burn without that kind of damage. Perhaps a bad heat seal of one of the cells.

What is the "the 'no rails' technology industry"? I'm not a programmer, but I thought that Apple supported Ruby on Rails, or is he referring to something else?

“We all have to be intellectually honest, and we have to admit that what we’re doing isn’t working,” said Cook, in an interview with former TIME Editor in Chief Nancy Gibbs. “Technology needs to be regulated. There are now too many examples where the no rails have resulted in a great damage to society.”

I think he's using rails as an analogy to regulation.

I don’t see the concluding for months and Boeing, along with the FAA, are going to pay dearly. 

It sounds like they were merely getting some conversion training as the type certification may be the same. Obviously that wasn't adequate.

I had some trouble understanding the problem that requires MCAS as a solution.

Most of the articles were describing how the larger engines had to be mounted further forward and higher to clear the ground (along with longer nose gear). That would, in my mind, result in a shift forward in the centre of gravity and result in a nose down tendency which is the opposite of what MCAS is correcting.

An article yesterday explained that there is also a shift in the thrust line. That's what causes the pitch up. If the pitch up is severe enough (maybe in the event of an emergency go-around) the angle of attack could go high enough to result in a stall of the wing. MCAS was supposed to correct for that.

Bad sensor readings may result in MCAS aggressively re-trimming the tailplane into a strong pitch down. If the pilot doesn't understand what's happening and how to override… Boeing ends up with a serious failure.

But, if predictions are correct and Apple has neither a foldable phone nor a 5G phone much less both, that hardware is going to look pretty dated this this September.

5G is still a bit of a s#!* show. There have been plenty of good articles on Ars Technica and other technical sites discussing the current problems.

It's a battery hog.
Different carriers in different countries are using radically different frequency ranges.
The back-end infrastructure often isn't there to support anything near 5G speeds.
