The cameras I have are charge and use, but should last about six months befire you need to charge again. We'll see. Mine are only active when I'm away and they sense activity so that should help.
They have cameras with solar panel and 4G. If they have an external battery I don't know.
Ref. quote from article:
"Chrome engineers operate a system called Finch that lets them push updated Chrome settings to active installs, such as enabling or disabling experimental flags."
I'm sure Google has the numbers since the Chromebooks/Chromeboxes auto-update (part of the whole point, really) so given that they likely have unique device IDs (or ethernet MAC addresses), the 'live devices count' would be rather easy to figure out.
It's a big deal because the upper left corner is where Android places notifications and thus you're likely to perform this operation frequently and in a number of contexts. Whenever you get a notification you're very likely to want to evaluate it (and possibly take action) as quickly and reliably as possible. On my Nexus 5 I can easily unlock, swipe down and swipe left or tap with one hand and very quickly as well. On my OnePlus One unlocking is fine, but getting to the top left corner is tricky, slow and unreliable when I'm using one hand, and two hands is not always desirable or practical depending on the context.
When you pay using the debit card, you have to insert the part of the card with the chip into a reader and enter your pin. Typically you can not do this until the cash register has transferred the amount to pay to the terminal.
You can also use it as a credit card when abroad or even in Norway. However, I'm not sure if the card will actually allow you credit (i.e. borrow money) per se -- I believe the account must have a sufficient positive balance, and I believe the domestic terminals are able to check that in real time (i.e. in a few seconds) and decline the sale if not funded.
As for online purchases, every time I use it as a credit card, I get re-routed to a card verification process. This means I get taken to some third party site (typically Visa or MasterCard) where I have to authenticate using my password and generate a one-time password (pin) on my phone. You can also use a FOB, but I find a phone more practical. After the verification is done, you get taken back to the merchant site. This is the same verification process that is used for online banking.
After living 15 years in the states I found this to be a bit annoying at first, but that had more to do with the speed of the implementation and the fact that it's applet-based (Java and Chrome -- have to switch browsers and hope that you don't lose your session).
If I had to authenticate every time I bought something on Amazon it would get old pretty fast. However, one could simply authenticate once to indicate that this merchant is trusted. A new merchant would trigger the authentication before the transaction can be accepted.
