Amazon actually uses QLDB (just made public!) for most of the critical storage (like EC2 control plane). The data warehousing has been migrated to Redshift and less important systems might run off RDS or custom DB instances.
Why? Actuator will be a simple low-voltage magnetic coil with a magnetic core attached to the switch's paddle.
The power draw is negligible, actuator is only used during switching. The fire-starting modes are the same as in the regular switch - the almost-open contacts that just barely touch, creating a high-resistance path. The ways to work around this are straightforward (make sure the actuator can't latch on, use the tried-and-true mechanical design).
The whole home automation industry is missing the point. I spent a lot of time and money on trying different products and I could barely find anything worth using.
Let's look at light switches. What's the main requirement for a light switch? Yep, being able to reliably operate it blindly in the dark. Amazingly enough, quite a few vendors fail this. For example, GE ZigBee switches have almost a one second delay between pressing the switch and light coming on. Sounds trivial but it's actually quite a significant problem.
Let's look at smart outlets next. What is the requirement here? Simple, being able to replace existing outlets in existing electric boxes. Again, there are barely any products capable of doing this.
I'm seriously considering funding a development of the wireless light switch done right - it'll behave like a regular switch but will have a mechanical actuator to flip it remotely.
Kidnapping for ransom is effectively impossible to pull off in the US. There's simply no way to get the payment that can't be traced to you, so only dumbfucks like in your link would attempt to do it.
So how do I get a refund on a Bitcoin purchase? Oh, yeah. I can not.
You also misunderstand how VISA works. The settlement time in the VISA network is 7 days. So once I sell something I can expect money in my bank account within 14 days.
VISA allows for 6 month chargeback window for customers. If a customer's bank issues a chargeback then the merchant's bank is legally required to wire money to the customer's bank. But this is a separate transaction, unrelated to the settlement itself.
If you want fast transfers, then just use SWIFT. They are usually completed within minutes these days.
The state should have reasonable ways to investigate crimes that involve large amounts of money. Right now a lot of crimes like kidnapping for ransom are effectively impossible to do because the payout can be traced (even with cash, by serial numbers on banknotes). A truly anonymous currency makes them possible.
What is a good use for anonymous currency anyway? Buying drugs and hookers?
In this system coins are good only for 1 transaction, but it'll be anonymous. Attempting to use the coin in another transaction will invalidate it and de-anonymize it, though only with 99.9% probability.
You don't need to do _perfect_ blind signing. It becomes possible if you accept a small probability of fraud (say, 1/1000) in the way of double-spending.
California stopped using the forest service to clear fire breaks because "we need to conserve nature man".
This is a lie.
California does not prohibit fire breaks. They are simply completely ineffectual in case of most CA fires. These fires easily cross firebreaks because of dense and dry vegetation and then jump back to trees, as there's a huge number of tinder-dry dead trees from the recent drought.
The best way to fix it is to remove dead trees but this requires a lot of money and effort.
This is called "urban heat island effect" and Watt's Up With That research has conclusively proven that it's being corrected for correctly and it's not affecting the measurements.
You can't cut yourself from the grid by only using Powerwall, you simply won't have enough buffer to ride through cloudy days. You can use Powerwall to shift your consumption into off-peak hours, but that's about it.

I'm using ZWave switches from Eaton. They are sufficiently OK, but they still lack the tactile feel of a true paddle switch.

A dozen or so in my house. I'm looking at converting the whole HoA so that'll be around a hundred eventually.
Can you give me the mark and model?
I asked the customer support and they told me that it's an intended behavior to allow double-clicks. Can you share the firmware you're using?

Tesla has 35% profit margin on every car it makes. This is even better than Apple and is unheard off in mass-production cars!
Of course, they are not yet up to the size of GM or Ford. Yet. But give them 4 years and see what happens.

There are other alternatives for centralized coins, including the ones that use symmetric crypto only.
So in this graph 88% of scientists who published in climate science journals believe that the GW is either man-made or equally natural or man-made.
The greatest deniers are basically TV meteorologists, the ones that published no papers: 16% flat out denial.
So yep, you ARE from the Church of Ignorance and Lies.
Your article contradicts what you're saying: https://journals.ametsoc.org/n...
I guess you're from the Church Of Ignorance, aren't you?
Hey! UAZ is a monster car. It works even if mistreated horribly and usually can be repaired in the field.
Was the Taiwanese supplier just going to forget about getting paid?
You'd be surprised how much slack exists in dealing between large corporations. Million dollar invoices can legitimately get lost or misrouted.

Except that it only does it with the drivers' license. If you don't have one - you're screwed.

Republicans haven't been conservative in their actions since the 90s.
What exactly should be "Conservative"? So far it's basically the transfer of wealth from poor to rich people, massively accelerated by st. Reagan.
And even on issues like gay marriage, the outcome is as scripted as professional wrestling
Don't bet on it. It's going to be curtailed by the new courts. Trump has already discarded trans people after using them.
Republicans do. Conservatives don't. It's still mostly the Establishment Uniparty in charge, which is why so little changes.
Erm... Look at the word "Convervatism" in the dictionary? Preserving the status quo is the whole reason for the Republican party.
You can buy multiple PowerWalls but at this point you will never recover the money by not paying for utilities.
You can't cut yourself from the grid by only using Powerwall, you simply won't have enough buffer to ride through cloudy days. You can use Powerwall to shift your consumption into off-peak hours, but that's about it.
