It looks like Apple has still not applied in Canada as of March 2019 https://mobilesyrup.com/2019/03/21/health-canada-apple-apple...

Fingers crossed for Canada to be next.

They were very open about the study and it needed a separate app to be installed https://med.stanford.edu/appleheartstudy.html

The feature is subject to approval process in each jurisdiction similar to FDA in US.

I think it it's more like someone locking your front door.

The HyperLogLog was a very nice article, but I wanted to ask, is this related to the estimation of Naci tanks during WW2 by Allies? https://www.wired.com/2010/10/how-the-allies-used-math-again...

Well in the article is a photo of Ted so I think they assumed no description was needed.

I think this has to do with types. In what you propose the returned type for primitive types (int, ...) would always be `Nullable<T>` and you would have to cast them to get the type `T`.

In many cases you can guarantee that the sub-property is not null and you can safely access the value. I think the proposed operator `.?` is the perfect solution and gives you the flexibility to decide what you can guarantee and how you want to access the sub-property.
