What I don't quite understand is why doesn't the software combine the pitch of the aircraft from the AI together with the vertical speed from the VSI and the airspeed to calculate whether the aircraft is at a dangerous angle of attack for a given airspeed.
I also wonder if a number of the software engineers protested and said it was a really bad idea but were overruled by management.

It's in the comments.
If they had taken data from more than one sensor in account they would have needed a procedure for how to handle contradicting sensor information, with a following change of the manual that would have turned it into a new model. With associated costs.

Thanks - so basically they sacrificed the safety of the passengers to save money?

I believe it is actually worse than that. Apparently, there is an MCAS override system, operated by a cockpit switch for use in case of malfunction. However, as it was not required for certification, it became optional extra at considerable cost - so there was no way to turn it off unless you paid for a safety feature that wasn't necessary for safety according to Boeing and the USFAA.
Ransomware, anyone?

I had heard about the switch but i did not know that it was an 'optional extra'.
I wonder if the jets that crashed had that switch.
I smells a bit like the banking scandal where banks were seen as too big to fail, Boeing and Airbus being the main suppliers of passenger aircraft perhaps they are seen as too important to modern transport for their aircraft to be grounded.

I know for a fact that the Lion Air 'plane didn't, as the director of aircraft maintenance for Lion is a personal friend, who retired two years ago, and he told me so.

Um, so you're not familiar with US corporations?

I'll, continue, to drive.

However, as he points out in the article, cars use drive-by-wire systems too.

Traditionally we visited the tulip fields in the Noord-Oost polder, my favourite tulip was present again: Shared album - Google Photos[^]
This year not a lot of Japanese tourists, but mostly Germans.
Did they follow me after my visit to Aachen I wonder

I went for a bike ride around Lisse yesterday. Lots of Japanese tourists, boy friends dutifully photographing their ladies for Instagram and for the first time in NL I was fearful of the traffic while cycling. Flowers were nice but I wouldn't do it again on a public holiday.
|
|

|
|
So that's where the Japanese were, hope they didn't trample too much on the flowers 
The region where I was, near Emmeloord, is a lot less touristical.

This was your first time cycling? 
This Tweet by Teunkie[^] says it all:
Crossing the street in Amsterdam:
look left
look right
look left
look right
look up
look down
look left one more time
look into the 4th, 5th and 6th dimensions
look into the past and the future
look into the souls of your unborn children
cross
still get hit by a bike

I tend to avoid Amsterdam at all costs

You put this [^] into my head (damn it!)
There must be some rule against this.

I genuinely DGAF what you link to (malware included), but give warning when linking to noisy video content, eh?

I notice that the article fails to mention that storing an unsalted hash is as bad as storing passwords in plain text.
