Genuine question – how does it “use” that water? Isn’t it primarily utilized for plain old water cooling, where in mind it just evaporates at worst?

What are we going to do, build high speed rail!? A technology so advanced that China alone has enough track in active operation to traverse the US over 13 times as of three years ago? I dunno, seems like a gamble

It doesn’t rely on phone navigation for starters :)

I find it to be especially useful for running, or really sports in general where it’s not practical to carry a phone. Accelerometer step counting alone isn’t very accurate. Having GNSS on the watch is very helpful in a lot of ways.

Or a Bangle.JS 2 if you like GPS :-)

Open Courseware is excellent so far! I’ve done their intro to C (as a refresher) and Intro to Algorithms courses. It’s definitely worth the time.
