Is that US-only or is that the story they are telling?

I look at Spain and Italy and Greece and while they didn't have the best economy to start with, it was the bailouts that did them in.

I also wonder, where did these billions come from? The stock exchange is a zero-sum game. So who paid these billions to the taxpayer?

Which manufacturing capacity does ISIS have left? Which engineers have not yet run away from the sinking ship?

Someone is using ISIS as a test run for their latest toy, and it's not the Russians (they would test by themselves). Expect the US or some of its allies to use weaponized small drones in the next war against the next terrorists, the result of "years of military research".

Different problem.

Yes, the provider could initiate a man-in-the-middle attack against all users from the start. However, let us assume that he didn't do that, for various reasons that are for a seperate discussion.

In such a scenario, Alice conversation with Bob is secure. It requires only the initial secure key exchange. Once that is complete, they are fine.

But with the backdoor of silent key-renegotiation, the provider can at any time decide that now they want to eavesdrop into this or that conversation. Say, because a government agency asked them nicely, or a FB employee looked up that woman he met last night in the database and found her WhatsApp number...

It is a different scenario with different ramifications.

He is missing the point.

The article is not speaking about an encryption flaw or anything like that, but about a backdoor - a feature that allows Facebook, without any code changes on your device or other intrusion - to eavesdrop on any conversation you are having.

A good encryption would be impenetrable even to the vendor. It should not allow the keys to be changed underneath you. It should not warn you afterwards about this fact, and only if you have a special option enabled, but it should tell you before it does a key change, and require your consent.

Comment Re: Unlimited? (Score 1) 196

Small cells negate the "limited amount of spectrum" argument. It's a financial + logistical + political/regulatory limitation, not a technical one.

Technology will eventually advance to the point that the financial consideration is less important. We're already working with beam-forming -- a technology that's existed for decades, in radar applications -- for instance. Wireless is the future, no matter what the naysayers think, and if you're still thinking of "spectrum" as the limiting factor you're behind the curve. Makes me think of the folks who deploy IPv6 for the first time and start worrying about the "waste" of addresses.

There's no technical reason why an LTE network can't be engineered to provide truly unlimited data with acceptable speeds in most instances. There is, however, a financial reason, plus the usual regulatory/political concerns that get in the way of new cell sites. It's worth noting that T-Mobile manages to offer unlimited with an asterisk (video throttled to 1.5Mbps) and in many cases delivers superior speed than Verizon, so it's clearly POSSIBLE and PROFITABLE to use as a business model.

In rural/fixed-wireless settings LTE is actually cheaper than DSL/cable and the favorable contention ratios (i.e., low population density) make unlimited possible with today's network. It's a mystery to me why they won't offer an unlimited product for this market segment at least; it would be the death blow for satellite internet.

It is not the same problem, though. A self-driving car needs to navigate from A to B by itself. The Tesla autopilot is closer to an airplane autopilot and requires a human driver at the wheel ready to take over, so if it can cover 90% of the drive, it's absolutely fine.

For example, my current way to work is largely freeways and if my car could manage that part by itself, which by time takes the largest part, I'd be happy to manually drive the first and last few km. While a completely autonomous car would be cute, I'd be happy to take a 90% solution.
