At in Germany Internet was just essentially free. You had some "Bürgernetzverein" which provided free Internet paid for by its members. Being a dial-up provider now is in fact even easier than ever before. You just set up a modem on your 3rd phone number and there you go. However flat rate telephone service came only after DSL so dial-up quickly disappeared because it was hugely expensive.
This is a website with a community. The experiment was largely publicised before and people knew how to get to them easily. There were no complaints about outage in the forums afterwards. In fact they have no completely switched to dual-stack.
So in short, I do not think that much more than those 5 had a problem.
It's no problem when your OS doesn't support IPv6. It's a problem when your OS supports IPv6 and believes it can reach the internet via IPv6, but can't. That's a _really_ rare condition.
They had their servers respond to both IPv4 and IPv6 on the same domain name for a day. Among one million visitors they only had 5 with a problem. 2 could be solved by rebooting the router and or the computer, 2 had unreleated problems with their internet, and one actually had triggered a bug in the OS.
Seriously, nobody who ever worked at a company and studied thinks that companies are a good idea. Essentially the only thing they are useful for is to kill creativity and to waste resources.
Let the people study in piece and what's more important, give them _time_ to be able to realise their ideas. Such an environment gave us Unix or many programming languages.
The basic problem is like this. If you do something on your own, you get the idea, work on it, and eventually it gets done. In a company you get an idea, then you need to ask for permission to work on it, writing proposals and making presentations while trying to find someone in management who accepts your idea. After spending more resources on promoting your idea than implementing would have cost, the project is cancelled.
The point is there isn't much competition between Windows and Linux. Windows is mostly used by either Fanboys or people who don't know anything else. There are few people deliberately deciding to use Windows, and for those who do the main reason is extreme backwards compatibility. That's why Vista didn't sell. In a commercial enviroment you "buy" software meaning you get a binary file of version X which you can hope to execute on your newer computers.
(Oh yes, there are in fact _some_ people who don't understand security and believe the recent advancement of security somehow outweigh the braindead software distribution model of Windows)
Once there is a simple, uncontrollable way to distribute video with those boxes, the industry will have to react. After all, it's trivially simple today to just record a whole television station.
People today are contempt re-inventing the flat tire.
One prominent example is the light-pen. Back when the first one was invented, the creator figured out it was a bad idea, as it's uncomfortable to hold your arm in the right positions for longer amounts of time. Yet it got re-invented over and over again, and even today we have desktop computers with touch-screens which have exactly the same problem.
He's also responsible for getting the recording technology in the US up to international standards, even experimentation with early video tape recording.
Well Logo is hard to get, but it would certainly be one of the more interresting languages.
The problem with C is, that it hides the native structure of a machine language program, but not the pitfalls.
On a BASIC computer you can just go there and type:
10 print "Hello World!" 20 goto 10 run
And you have something interesting. It's also interactive. You can just enter print "Hello World!" and just execute that line.
Please do not confuse BASIC with those "new BASIC" languages like Visual Basic. Those are essentially useless. If doesn't have mandatory line numbers it is not BASIC.
Of course, but I believe we need to differentiate between 2 goals. Computer Literacy and professional Computer Literacy.
BASIC is great for the first purpose. It shows people what you can do with a computer. It's a "toy language", you press some buttons and it makes some noise. From that you can explain concepts like loops and such. It's like teaching children how to write phonetically. It's not really proper, but a stepping stone towards true literacy.
However it's wise to go further with a language like Pascal. Such a language can teach children the finer aspects. Like how to structure a program. Pascal has a lot more overhead. You need to define variables, you need to have a header to your programs, etc. The main purpose of it is introducing the beauty of structure and discipline in programming. It appeals to an older audience.
C is probably one of the worst choices. It claims to hide the machine and makes many things ackwardly hard and complex. It's very hard to get to a point where the student can derive motivation from what he does.
Well I first learned BASIC on my own on a TI99-4a and a ZX80 (with the ZX81 ROM). At school I learned Pascal.
The graphics is fairly important as it motivates people. If their programs can make something "cool" they will learn faster. Unfortunately this is getting more and more difficult.
PHP or JavaScript doesn't teach them how computers work. This is not about leading them to a carrier in IT, this is about giving them the nessesary knownledge to be able to live in this society.
Again, it's like math. The math you learn at school is completely useless for every day life. However it gives you a tiny little glimpse of what math is.
Programming is essential. As a model language I would recommend an old BASIC with line numbers. This is close to how computers actually work, but still accessible enought for them. If you want to have an advanced course, teach Pascal.
It is essential in our modern world that people, especially children, know how computers work and how to program them, in principle, at least. We also teach them how to do math, although they are very unlikely to multiply larger numbers without a calculator or solve an equation.
The point is not to turn them into great programmers, but to give them a basic idea of how the things work. To make them able to estimate the limits of computers and how hard a certain task is for a programmer.
The worst first language would probably be C(++,#, Java,whatever) or any of those new fancy languages, because they hide the machine to much and add lots of complicated concepts to get wrong.
I find those "how to use application X" courses absolutely useless. Most of what you learn there will be found out equally fast by the children themselves. And everything will change at the next version of application X anyhow.
Prioritizing packets only makes any sense in congestion situations, otherwise there is absolutely no effect of it. Today congestion can only happen at the users uplink, and good routers support trafic shaping under user control there for years.
If there is congestion in the backbone, the ISP is not doing it's homework.
Well you should look around at the OpenWRT or X-WRT homepages, they have good english info on how to install decent Linux distributions on those routers.
The rest is fairly simple. You start an Adhoc wireless network and assign IP-Adresses just like you would do in a wired network. Then you start the olsrd which takes care of the routing. Alternatively you can try batmand which is a newer routing protocoll which works on Layer 2.
Great. As a cheap router I can recommend the d-link dir-300. It's good as a network node, but for connecting it to a VPN I recommend installing an SD-card.
OK, then just do so. There are dozends of such projects which can help you. For example the Freifunk movement in Germany. They even have nice motivational videos and all. Also they typically run VPNs to connect nodes via the internet.
They also offer pre-built firmware images for a variety of routers.
...it needs competition, however capitalism as it's done today favours the large. If everybody would play by fair rules and be a good citizen, society would just work perfectly without any regulation. It wouldn't matter if there was a dictatorship or a democracy, it would just work.
However since not everybody is a nice person, we need control, and net neutrality is one of those.

Well unfortunately they still probably have the technical possibility to remote-delete application.

Now add variable delay lines and there you go.
Unfortunately you cannot re-design Windows without breaking compatibility. Microsoft has tried and the result is called Vista/Windows 7.

At the moment it's better to wait than to use any of those two. They both have no long-term future.
However if you only have a short term project and you really need something _now_, Flash is just somewhat more availiable.

Yes, but they are lobbying politicians to ban such things, or to ban support for it. Of course this doesn't change anything in reality.
Anyhow, are you already a part of such a network?
But the ISPs are strongly opposed to that.
