This sounds great in theory but, in practice, it's going to be almost impossible to enforce (eg whose definition of 'vulnerable'?) and it would promptly create several new Internet plagues, eg the "Your server has a vulnerability, pay us now to stop us reporting it" spam email.

The picture you paint of Europe is a little simplistic too. France has a few large cities, but the tenth-biggest one has less than half a million inhabitants. It has tens of thousands of villages with 1000 or less inhabitants. And you get a choice of cheap ADSL provider in most of those small villages.

The answer to "Could someone else make this thing I just made" is always "yes", eventually. We have patents to slow the arrival of the "yes" answer enough so that the first person to do so gets to make a bit of money.

But in this case (and most other cases) there's more than one way to do it and a lot of relevant technology, a lot of which is general car technology. And in every case, sooner or later, the huge company with a huge patent portfolio and huge expertise in manufacturing is going to win the "lowest price point" game... if they want to.

At the moment, the big players don't think there's a big enough market to make it worth their while to compete aggressively. At some point that will change, and at that point GM and other huge companies will develop, licence or acquire whatever technology they need. At the moment, Tesla is selling a niche product. That's great, but it hardly the same as producing electric cars for everyone.

Or, to put it the other way round, does anyone see Tesla scaling production up to anything like GM's level while GM quietly hands them market share and eventually gets out of the car business?

My experience is that I have to read 10 Stack Overflow responses to find one that gives me a clue to the right answer... and that this is still usually a faster way to find a solution than trying to work it all out myself. It's usually one of the "No, that's wrong because..." post that turns the lights on for me.

I can't see how this tells them anything useful about price points for retail sale. The people who pledged money are agreeing to buy an untested phone in a year's time. That's way beyond even "normal" "early adopters". To do that, you have to be really passionate about new technology AND be able to pay a premium price for a phone you can't use for 12 months.

I've spoken to several people who, like me, might well have paid if the phone would be shipped today or in a couple of months. But with the timescales in the proposal the "price points" are for venture capitalists plus people with money to spare who just want a slice of a neat idea.

None of this tells us anything about how much they could sell production phones with this spec for in a year's time, and it's pretty much certain that to achieve any kind of market share they'd have so drop prices compared with the ones they tried this month.

I'd be interested to see the answers broken down by age. It may well be that most of the people who love paper books will be dead in 20 years.

I suspect there's also a "fake good" effect, in that people feel they ought to be supporting their local bookshop and therefore say that they do, even if, in fact, they buy a book a year in an airport and every other book on Amazon.

Personally, I really like paper, even for technical books, but all my colleagues look at me like I'm wearing sabre-toothed tiger skins and wielding a club.

I think that everyone should learn to code. Not because it will make them a programmer. Not because it will enable them to estimate how long something will take, not least because experienced programmers are legendarily bad at doing that anyway. Everyone should learn to program because programming makes the modern world go round, and it's good for everyone to have at least an inkling of what that involves.

We teach a lot of kids chemistry, without any expectation that they will invent a new compound that will change the world. We teach a lot of kids physics, without any expectation that they'll make a significant contribution to subatomic particle research. We teach most kids to do creative writing and poetry, without expecting the vast majority of them to produce fiction or poetry of publishable quality. I don't see why we wouldn't teach programming alongside all those other topics that most students never master and never "need".

One argument for teaching a lot of academic subjects widely is that the skills you learn along the way have wider application than the topic itself. And it seems to me that this argument holds at least as well for programming as for, say, pure math. As programmers keep saying, programming is about analysis, structure, models... is there really no application whatsoever for those skills outside of hardcore programming? Does no-one ever wish that their managers had a better grasp of "system"? Yes, of course, you can acquire these skills in other places. But the thing about programming, pretty much from the outset, is that your pious beliefs about system will stop your code from performing correctly unless those beliefs are reasonably accurate. I sometimes tell people that I do executable philisophy - it's all about logic, but, unlike the philosopher, my logic has to work.

No, a bit of Python won't enable people to produce estimates for projects. But it may enable managers to understand why writing code once to do something that needs doing often is often a good plan (and, also, why it sometimes isn't). It may enable managers to understand why "Can we just change this one assumption" at the end of a project may involve restarting the entire project.

Yes, a little knowledge is a dangerous thing. But the little knowledge is out there already on the TV station of your choice. I don't even like Python that much, but I'd still much rather deal with erroneous assumptions based on a bit of Python experience than deal with erroneous assumptions based on watching Mission Impossible and NCIS.

"It's probably now at the point where new projects are better off starting with Python 3, to ease the pain of upgrading later, unless there's a library they really need. Starting with a mature (but depreciated) platform is not a great idea."

Unless you want to use Python on Google App Engine, where Python 2.7 is what you get. And given that Guido himself works for Google on this project, that's not exactly encouraging.

Or unless you want a Python app to work out of the box on, well, just about anything, but OSX is the example that bit me.

I remember discussing Python 3 on /. when it came out. The decision not to even try to ensure backwards compatibility struck me as disastrous. The response was "No, because Python will never have a cruft problem because we are not Perl coders", or something like that. Many years on, I still think it was disastrous. Python now has a bigger legacy code problem than Perl - seen much Perl 4 recently? - precisely because the upgrade path is such a pain.

Killing Python 2 is going to be like killing IE6 and Windows XP - a noble goal that turns out to take decades. And it's a totally self-inflicted wound by the Python community.

For households that heat electrically, incandescent lighting in winter has to be an excellent idea. You get the light, and in the end all the electricity turns into heat, which is distributed really efficiently across the room. Replacing the light bulbs just means the electric heating is going to work that much harder.
