Right now I only see one positive comment in the whole thread, did you see more when you posted? I’m curious if some were deleted.

Definitely, some code is much more readable/clean in C++, while still compiling to reasonable VHDL. Also templates let you create fairly complex blocks programmatically at compile-time, Verilog doesn't have the same metaprogramming facilities that C++ offers.

Sadly you can't synthesize any old piece of C++, there are a ridiculous amount of constraints and you need to write the code in a very specific way.

Also there's not necessarily much of a performance gain, some tasks are not good candidates for being implemented in hardware (as a general rule you need a lot of parallelism to make it worth it). As an overly simple example, implementing hardware RSA and hoping for a significant speedup doesn't make sense because there isn't really much parallelism and it's usually only used to encrypt keys, but something like AES or SHA might benefit from a good hardware implementation because there is much more parallelism to be had and they are used to encrypt much larger amounts of data.

To add even more complexity, the compilers can be obscenely finicky with optimizations.

I thought they were saying they're going to stop selling the current standard one, and the new "standard" will be the software limited plus, and that it will only be available at a store and not online.

Same for me and I've used Apple Maps all over the US. Although there have been instances of Google Maps finding something Apple Maps couldn't, I've never actually gotten wrong directions.

You're right -- I thinking more of a clinical context, which is definitely the wrong frame for this. From what I've read online, it only seems to detect AFib, which is obviously useful since I think it's the most common abnormal rhythm. Maybe it's only able to detect AFib since it's just on the wearer's wrist? I wonder if there are plans to make little wireless sensors pads to mimic having more leads. That'd be pretty cool

I missed the part in the stream about FDA clearance, but my guess is yes, it would be some sort of medical device. However comparing the ECG functionality available for an apple to watch to even a standard portable 12-lead ECG is like comparing a slide rule to a modern GPU. It is definitely _not_ a replacement for going to the hospital, but it is a novelty and might be a good way to tell someone when they should go to the hospital to get checked out.

For some of these people, the fact that there's natural splendour there isn't the point and isn't relevant

I can't think of a single climber, mountaineer or ultra runner I know that any of that applies to (including myself). Do you have any actual examples of people like that?

setting is just a convenience

Nothing about ultra running in the mountains is a "convenience"... in my experience the opposite is true, and almost everything done in the mountains is done easier on flat ground.
