The web in insecure, don't store passwords in the web. Use keepassx instead. You get it for Windows and OS X on the site, for Linux using package managers, for Android on the Play Store and maybe also for iOS (look for MiniKeePass).
I didn't wear anything on my wrists in the last 25 years and I can't think about any feature that would me want to do it again. One of the good features of a phone is that you put it into a pocket and take it out only when you need it. Your hands and wrists are free. When I go cycling I've already got my bike computer, on the bike. About monitoring all those quantified self things, they don't matter to me.
They don't connect the dots for everybody for free. Become a strategic partner (that is: find a way to bring them more money) and they'll be happy do connect the dots for you. So don't be naive: Apple cares about its customers only when it can turn that care into profit.
BTW, this app does the same on a rooted Android device.
All Formula 1 cars had active suspensions in the early 90's. They were computer managed to keep the car flat in the curves and maximize aerodynamically generated downforce and also to absorb impact with kerbs in chicanes with almost no rebounds (more traction). Actually they were introduced by Lotus in the early '80s but didn't get mainstream because of weight and limitations in the electronics. Williams had a better version of them in their 1991 car (electronics got much better by then) and eventually all the team followed suit until FIA banned the technology starting from 1994 because of safety concerns (Zanardi barely survived a heavy crash due to an active suspensions failure). More details on F1 active suspensions here.
Production cars used them since the 80's.
What Mercedes is doing now is reminiscent of the early Italian high speed train Pendolino. "By tilting, the train could go around curves designed for slower trains at higher speeds without causing undue discomfort to passengers." See one of those trains tilting in a curve in the UK in 2012.
I wonder what will happen when an hex fails. Would the driver assume that an obstacle is on the road hiding the hex and needlessly (and maybe dangerously) brake?
I'm not saying that this technology doesn't have any advantages over standard lightning but maybe they are too far into the curve of diminishing returns.
By the way, how difficult would be stealing a hex and bringing it at home to turn it into a fancy table? I see plenty of opportunities for vandalism. Unfortunately this isn't a nice world.
We don't need another source of light pollution.
I have a 16 GB laptop and I don't have any swap. I never run out of memory. free -m tells me that it's using about 4 GB for programs and data and almost 10 GB for file system buffers. I understand that I could get some more buffers if it compressed in RAM those pages that would have been swapped out, but is that really important? If you have little RAM you don't want to swap into it, if you have plenty you don't swap.
