No, it is the exact opposite.

Stickers and security awareness training and all this nonsense are attempts to put the responsibility on the user by telling him what to do, instead of handling the responsibility yourself by making sure that your product is safe.

As with all things, there is, of course, a limit. You cannot (with current technology) design a power drill so that it will work on a wall, but not on a hand. And if your user knows the master password that will destroy your company then he should be told to keep it secret. But you should also ask yourself if you really need such a gaping security hole or if you couldn't compartmentalise things better. Or if the power drill can be designed so that it only works if the user has both hands on the machine, to at least reduce risk.

Not friendly to disabled or old people.

However, one-way walkways are entirely possible. You could have moving stairs that only move in one direction - that way a user erroneously going the wrong way would definitely notice.

It's all about assuming that users make mistakes and changing your mindset from shaking your head and mumbling "stupid lusers" to "let's see how we can handle that..."

It's quite an interesting subject, and finding great solutions to these problems is a challenge to more than just math skills.

You believe that user interfaces have to be made either for idiots or for geeks. Nothing could be further from the truth. A good interface allows both automation and is tolerant of failures. This is not only not exclusive, it is mutually supporting - when you want to automate something, proper error handling is even more important.

I'm quite sure they (Ferrari) could, if they wanted. But it would destroy the brand. These brands are built on exclusivity, on the "not for everyone" factor - not only due to prices, but also due to the type of car they built. I'm quite certain that almost everyone who actually owns a Ferrari also owns at least one other car, for everyday driving.

Tesla, on the other hand, is trying to become upperclass mainstream. I wouldn't compare it to Ferrari, but to fashion designers - their original creations are unique exclusives, but they can inspire collections that are affordable to the average girl.

"User errors are user interface errors."

Last line of a keynote speech I gave two years ago. If someone walking back through that exit is so serious that it causes this, then it should not be possible, period.

It's easy to prevent. You post a security guard there, and/or you use appropriate doors. The last is a bit tricky due to large passenger volume and baggage, but some airports I know have these doors just before the baggage pickup area, for example.

He didn't cause the delay. If you build systems for normal users, you have to expect them to make errors, and the system has to catch those errors and handle them in a non-fatal way. If it doesn't, your system is broken.

And free sites. They still exist - I run a couple myself. I found that for me, a mix of free and paid sites covers almost everything I need on the Internet. You just have to spend a little time finding what's for you instead of always following the top three Google hits.

Russia is independent of the USA part of the Internet to a degree you can hardly imagine. They have their own Facebook (vk), their own Google (yandex), two DNS root-server anycast instances, and even for credit cards they'll not be very sorry as Russians prefer debit cards from their own banks over Master/VISA credit cards.

Sure it'd be noticeable and some stuff would stop working, but it is certainly feasable.

If they ask, I'll consider it and I may decide this way or that.

If they lock me out without ads, I'll never visit their site again. I don't want ads, they don't want me as a visitor, we seem to have a concord.

Exactly. You're the kind of people they want to keep out. People who think that $5k is a waste. For their target audience, $5k is either not worth even thinking about, or a fair price to pay for making sure you spend your time only with people who fall into either of these categories.

Those TV and music starlets will stay on FB because they want and need to stay in touch with their fans.

The wealthy have always segregated themselves. That $10k membership fee in the golf club is not because keeping the grass short is so expensive, either. It is to make sure everyone you meet there is in your class.

Frankly speaking, I'm mostly surprised that this doesn't already exist.

So it closed last year, but you only just noticed and posted an article? It doesn't seem like it's going to be missed very much, if the corpse can decompose and start to smell before someone sends the police to check on aunt Mozlabs.

Also because we already betrayed them once and they're not necessarily our best friends because of it.

Mostly by changing allies the way other people change their underwear, yes.

Americans killed two or so orders of magnitude more civilians in the middle east than arab terrorists killed in the USA. Somewhere on that road, the justification became a cruel joke.

If I'd say I'm underwhelmed, it would be a big understatement.

Every major device announcement that Apple made in the recent years was always driven by one thing: It had a purpose. It provided something that was lacking in the world. Not a totally new invention in many cases, but a solution. Smartphones existed before the iPhone, but it is clear that the smartphone market history can be divided into "before the iPhone" and "after the iPhone" - just look at pictures of smartphones from those two periods.

iWatch? I know it was rumoured for two years or so, but in all that time I couldn't see which problem it solves and what meaning to life it has, and I still can't. It seems the Jobs spirit has left, because this is clearly a device that was made in response to the rumours about it, not because someone knew what he was doing.

That's the problem there, can you spot it?
