That had nothing to do with security.

It was simply that Blackberry was using BBM and people were sending data-based text messages to each other.

Everyone else was using classic flip-phones and trying to call each other, and the cell networks were overloaded.

Getting a few bytes of text that would auto-retry in the background was reliable. Getting an open voice slot on a cell tower was not.

Of course the best way is with metered usage (pay per GB you use in a month). But for some reason everyone seems to be totally against that even though that's the method that makes the most sense.

It doesn't make the most sense. It is not a consumable resource that had a one to one cost, like water.

What makes the most sense is classes of service: Dedicated bandwidth that matches what you are paying. A simple example: ISP has 1,000 gb connection and 1,000,000 subscribers. So, every subscriber would have a 1mb dedicated class of service, and would pay for their share of that.

Now, obviously, there will be times where they can download a 1gb, or whatever the size of their pipe is. However, during prime time, they would reduce down to 1mb, but no less.

If they wanted more, then they could pay 5x as much for 5mb dedicated CoS, and they wouldn't slow as much during the prime time.

And the thermostats need to be online because....?

Because some power companies currently and more will soon give you a price break for cutting usage during a surge in demand. Sometimes this can be predicted, sometimes it can't. Hence the need for real-time comms.

Wtf? Perishable food needs to be kept cool regardless of the price of the electricity unless you want to risk food poisoning to save a few pennies.

For a refrigerator, you're likely right. Think about a freezer, though. Maybe you're set to -10C most of the time. However, you're going to be gone all day and your usage patterns don't show you opening the freezer in the morning, maybe it is better to cool everything to -25C overnight, and then NOT run the compressor until you get above -10C again. During the evening, though, DON'T chill it to -25C, because you're just going to open the door again and let out all the cold.

There is absolutely NO reason for ANY kitchen appliances to be online or have any kind of network presense whatsoever unless you such a bone idle sack of fat that you can't even be bothered to open a fridge door to check whats inside but would sooner do it via an app.

Opening the door is what creates energy usage. Having an app to keep inventory can drastically reduce usage as you stand there like a bone idle sack of fat and stare at your inventory, letting all the cool air out that your device will use electricity to replace.

Comment Re:Most NTP clients I've seen... (Score 2) 132

This is why it pains me when I see two NTP servers setup. You NEVER know which one is right. Having just 1 is better than that.

To me, the minimum is 4: This gives you n+1, since you need at least 3 clocks to know if the time is right, and NTP will actually play ball with this logic: It will first look to see if 1 of the 3 are way off and exclude it, then it will sync time from the clock that is the lowest stratum and most stable.

Comment Re:Record License Plate Number? (Score 2) 328

And you expect to have that recording 24/7? Don't know how much effort the company wants to put into when they don't really expect this kind of incident.

No, almost all security DVRs will drop frames with no motion.
Good ones will OCR the plates and tie it to a single frame of the car, and save that for a long time with very little space consumed.

As for putting in effort, why even put up the camera if you're not going to record stuff like this?

Comment Re:And this matters *why*? (Score 1) 77

But we need to address the bigger problem with getting the bits to our door before we worry about how fast the bits actually move around inside our houses.

1. I've been using the Xbox One streaming to my laptop, which will now work in 1080p, but getting it to work on my 802.11n has been problematic. Plugging into my 1g wired connection solves it.

2. While, in theory, 802.11n should allow HD streaming between devices on my WLAN, the issue is that I'm in a moderate density area (1/4 acre lots. Not an apartment, but not in the woods), and I can see around 10-20 SSIDs nearby. The more everyone switches to 802.11ac, the less time each access point will be using a channel, and the less likely it will be that we'll be bumping into each other. Add beamforming, and the channels are getting even clearer.

Keeping people alive you know are faulty is kinda senseless unless you have ways to fix the problems.

That is an extremely short-signed view.

I thought ST:TNG did a good job of explaining this in both "The Enemy" and "The Masterpiece Society": The technology used to help a blind baby see was adaptable to other solutions where otherwise "unfaulty" people would benefit.

A review of key historical figures will reveal many with physical issues from birth.

The ability of a person to contribute to society, directly or indirectly, is impossible to predict.

Comment Re:Wait til the kids start putting Telsa doors (Score 1) 323

Obviously, they were designed by someone who has unlimited garage headroom

They don't look to be over 7' to the top when open, based of seeing a man standing next to them when open.
Most garage doors are at least 7 foot tall, and 8 foot & taller are becoming far more common.

and doesn't regularly find a foot of snow on top of his car...

Put the snow broom in the trunk, like most people. Open the trunk, clear off the snow so you're not an asshole to everyone behind you on the road, then get in.

Comment Re:Designing good test regimens (Score 1) 569

I just can't take seriously the idea that one would have to be a software engineer to design the test well.

No, the test was designed well for automobiles that have existed for 100 years.
The goal of the tests was to reduce the number of variables, such as pollution from other cars going down the road in front of the one you're testing, or the nearby coal plant.

Putting them in the same room under the same conditions makes a very good baseline...until SOFTWARE allowed the cars to cheat the tests.

I'm sure the people designing these test are great hardware people. I also think they just didn't realize that software had advanced to the level to do this.

Leveraging always beats prototyping.
