The Apple Heart Study is for the pulse detection, plus when AF is suspected a continuous ecg monitor is given to the patient for 8 days, this is NOT the Series 4, it’s a continuous monitoring device separate from the Watch:

I’m really skeptical of the articles on the accuracy of the ECG function of the new Apple Watch. Most don’t quote anything from Apple and don’t seem to understand the Apple Watch Heart study.

Apple has 2 clearances from the FDA:
One for using the pulse tracking (not ECG) on any Series 1 watch or newer to detect AFib:

The other is for the ECG feature:

- a microSD card weighs somewhere around 0.4g
- the highest capacity microSD that's easily available is 256GB
- a trebuchet can throw a 90kg projectile over 300m

90kg worth of microSD cards is 225,000 of them

Therefore a trebuchet can throw 57.6PB of data over 300m

This would have the highest throughput of any telecommunications network ever created


FEMA testing emergency "presidential alert" system next week. Odds that Trump will actually compose the text message sent and it'll be a partisan message?

darn it, as @jessicadennis points out, I missed the 3GS, I think that helps makes the point. Also, Apple’s iPhone page lists the new names as capital X lowercase s/r, previously they used uppercase S (when they don’t use the dumb s in a box).

So long as Apple doesn’t pick a name that translates to a literal sex act in another culture they’ll be fine. All Apple names are dumb for the first month.

Also, I predict the iPhone & macOS will lose their X at the same time.

Whatever scheme you imagine Apple has been following isn't there, it's just pareidolia.

They skip numbers, sometimes use a functional naming, sometimes a one off letter, sometimes S sometimes no S.

5 C for color? Can't have a "convention" if you only do it once. S naming, stopped with iphone 7, resumes with X S. There has never been an iPhone 2. 3G was for upgrade of cellular, S started out as "Siri" but became just a letter.

There has never been a rhyme or reason for Apple naming.

Wait, the iPhone XS has asymmetrical hole pattern on the bottom? Where is the outrage!

Apple named the iPhones to go for a scheme of 10 betteR, 10 beSt, and MMMMMAAAAXXXX. The max didn’t get its own letter because it’s identical to the S except size.

People that think product names need convey some purpose of the device are crazy. Look at car names - zero sense or meaning. Names don’t even have to be particularly good, look at the iPad - derided for a month as a feminine hygiene product name that faded in 2 weeks and still had huge sales.

"Kevin, please move the data for this project from a North Carolina server to some place less hurricane-y"

"Uh, sure, um, we actually did that last year, so.... done?"

So busy I have more email windows open than Chrome tabs

Who the hell scheduled me for a meeting right at the start of Apple’s announcements?
