  1. Relevance of computer use to education. on Students Outpacing Teachers With Online Skills · · Score: 3, Insightful

    It's late here, so I'm just going to pose the question. Is it relevant to children's education that they know how to operate a pc at a young age?

    I only started using PC's in the last year of my high school in 1993. Now I'm quite computer literate. I learned most of these abilities in university and just by figuring it out myself. Now I can understand that it might be handy to teach kids some basic skills, but what I see from kids is that they are quite eager and smart to teach those skills to themselves. What is important for school is to teach kids Reading, Writing and Arithmetic (yes, with capital letters). Those are the elimentary skills. Now you don't need laptops for that. Computers might help some dumb or smart kids, but in general I don't see any real use for computers in learning the three R's.

    I do think however that we should teach kids a skill which a teacher can learn them even though he is in his sixties, old and wise but with zero knowledge of anything that runs on electricity. It is how to use data and judge the value of it, so that when they interpret the data and shape it into something meaningful, they learn to draw the proper conclusions.

    Well, it turned into a rant anyways... but please give me your opinion.

  2. Answer: Yes Missionaries use it. on Ask Larry Wall · · Score: 2

    I know of some bible translators in a country I won't mention, where Perl is used to provide an automatic PGP-encryption of the plaintext emails into cyphered emails and vice versa, before anything is e-mailed out to the rest of the world or when received, before it is dropped in the mailboxes. For want of a real ISP the machine dialed out to a base of the same organisation elsewhere in the world where the same setup exists and from there the mails get send on in plaintext. All this is done to make sure that when communication is monitored no Christian texts are discovered.

    Now you might say that that is not secure, everything is still in plaintext on the server of the missionaries and you're right. (not to mention the bibles in their houses, the work stored on the computer etc.) The reasoning behind this is, that the censor/secret police in this country have a policy what they don't explicitely know about, they won't bother with. They can't read the e-mail, so they don't know about it, so they don't need to take action.

    All of this was hacked together by a bible translator (a linguist) on an of the shelve Redhat old.ancient linux machine. The man-pages provided enough information for him to finally get it all working.

    Some Quotes of Edsger Dijkstra
    "Always design your programs as a member of a whole family of programs, including those that are likely to succeed it"

    "Separate Concerns"

    "A Programming Language is a tool that has profound influence on our thinking habits"

    "The competent programmer is fully aware of the strictly limited size of his own skull; therefore he approaches the programming task in full humility, and among other things he avoids clever tricks like the plague" (from 1972 Turing Award Lecture)

    "Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code"

    "Program testing can best show the presence of errors but never their absence"

    "I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself, "Dijkstra would not have liked this", well that would be enough immortality for me"

Now, Western countries (yes, other democratic countries also have this problem) might say to third world countries that they need to do something about corruption, and rightfully so, but the democratic West needs to watch out they don't fall into the same pitfalls.

    I know it is hard to believe if you've worked in the military and know what is possible, but this one is really true. If you look at the .ram-movie it becomes clear that everything is encrypted untill it reaches virginia, then it gets beamed back to the intelligence community in Europe over a public sattelite with no encryption. I saw the tv-program and they had this American officer working for NATO, who kept answering that it since it went over the public broadcasting system it was unclassified and therefore wouldn't be of use to enemies of NATO. This is ofcourse the other way round. If his reasoning was correct we would also be allowed to watch life footage from Afghanistan. Better yet, why go through the trouble of encrypting it when it leaves the plane, if it can be seen within a minute from the sattelite. Another gentleman from the Pentagon was kind enough to say that they were looking into securing this information again. :-)

    I differ with you on that. It seems like no one in the parliament is willing to invest in it. The northern provinces now use the project as leverage to receive money for other infrastructure projects, like the proposed zuiderzeelijn and High Speed Line to Hamburg. The reasoning more or less goes like this: "We didn't get the 4(?) billion for the maglev train, we need something in return to make up for the loss of the money we never had." Great tactic, always works with politicians.

    The marginal difference lies not in the speed the train can achieve, but whether it would be economical to reach these speeds. 515kph has been reached with a TGV, which is 70's technology. The idea behind maglev was that it would require less energy to reach the speeds of above 300kph, thereby offering a trade off between the higher costs of building it and the higher speeds that could be achieved. As far as I know, it is more energy efficient than a normal train on wheels, but this difference is not large enough to warrant the investment even if you factor in the shorter travel times etc.

  11. Maglev not economically feasibble on Riding the World's Fastest Train @ 500 kph · · Score: 5, Informative

    Siemens has a test track for a maglev train in Germany, just across the border with the Netherlands. Though it is a very popular destination with groups of students, politicians and housewives, it hasn't convinced anyone (with enough money) yet that it is a good idea to build.

    There have been two cases for it in Germany and the Netherlands, Hamburg-Berlin and Amsterdam-Groningen, both times it failed on the excessive costs that are nescessary to build this track. The main problem of the system lies in the fact that at speeds above 300km/hr the magnetic system creates a drag of its own, so the drag of the wheels and track have been substituted. Furthermore the aerodynamic drag turns out to be a much more important factor than they first expected. So instead of being signifficantly more efficient at high speeds, it is only marginally more efficient at a much higher investment cost. That is why both the Dutch and German government decided not to build production tracks.

    You seem to forget that Intel is a pretty cool company when it comes to investing/helping out with a great research project. This can be done in many forms, shapes and sizes, but in my experience at my old university, you could almost always be sure that if it was cool and in line with Intels products, they would be interested in having their name attached to it. Funny thing is, the university loves Intel in the game, even if it is partially for the greater glory of Intel. Intel has so much clout it attracts other sponsors as well. Having Intel in a project is often a win-win situation both financially, scientifically and pr-wise.

  14. Contrary to popular belief, the Internet in't free on Comcast May Raise Prices On "Internet Hogs" · · Score: 2

    Yes, really bandwidth costs money. The lowest rates I have seen here in Europe at Internet Exchanges are 150 euros/mbit/month, which is about the same in dollars. This is the rate that telco's charge other telco's/ISP's. This allows you to burn up the full 1 mbit continuously. So that amounts to 150Gbyte a month in data. Anybody that sells you anything cheaper than this, is lying, cheating (or in marketing).

    Now I know that the marketing of several of these so called broadband companies has been way off. When they speak of unlimited, they mean that you don't run up a phone bill (in Europe) or that you can always leave it on. Not that you can just burn all that your line can do.

    The price that you're paying for current broadband is based on the simple arithmetic, that people won't always use all their bandwidth. If they do, the prices should be higher, other wise the ISP is going out of business. If you think you've got a right to use the full 2mbit your DSL offers, either pay the full amount it costs; 300 euros + extra's or you have been delusional and have bought into the marketing hype too much. If you've bought the marketing hype, you're not a bright nerd and you should consider it tuition for the school of life.

    But yes we do need that bandwidth. Espescially in Research and in Healthcare. I'm now doing some work on hooking up some healthcare organisations to glassfiber. They've done some interesting trials where they have several cameras and sensors looking at the patient, who is performing a walking excercise. The knowledge of the way a person is supposed to walk and the problems associated with that is scattered around the country. For half an hour they watch with several experts from across the country. Every doctor can interact with the patient and with each other. They can point things out to eachother etc. This results in better treatments and the identification of specific problems.

    The amount of bandwidth that is needed for this is quite high. 5 to 6 cams with real-time video and real-time sensor read outs and then real-time discussions over multiple locations. Now imagine they do this for multiple patients at the same time :-)

    I would suspect it is partially because this way the studios find out what the audience thinks of a particular movie and doesn't need to spend money on movies that won't make it here. So there is a bit of a profit motive involved and that is OK. Saves us from some of the crap in american cinemas. On the other hand, the European audience has a different taste than the US audience. So it might actually become a hit, would it ever be released. That is how British, French and Australian score. It is almost impossible for them to score in the US.

    Furthermore I would suspect that there is some arrogance from those studios involved as well. The way they operate, they generally see the US as their market and the rest of the world as something that creates a nice revenue, but nothing more. American companies in general have trouble dealing with the fact that the rest of the world is not one market with one common language etc etc. But instead of having a regional organisation that is independent to do what it wants, like the car manufacturers, the movie industry keeps their non-american branches on a tight rope and most of the decisions are made in the US.

    Can DVD sales suffer from internet piracy? Possibly. Can box-office sales? Nope.


    Though I mostly agree with you I want to add a bit of insight from a different location in the world. Here in Europe (and most of the rest of the world not being Northern America), we have to wait a couple of weeks to a couple of months, before a movie that has been released in the US, is shown here in the cinemas. If it ever shows up in the cinemas at all, because many movies, even good ones, go straight to video here or never are released at all. If you download a movie during that waiting period and watch it, you generally won't go to see it in the cinema, nor rent the DVD. So here downloading movies is hurting (in a small way) the sale of cinema tickets, though in my opinion it is mostly because the studios restrict when and if we can see a particular movie.

    The big record, movie and tv-companies haven't yet caught on to the fact that the world is a village and that people want to see and hear stuff when it becomes available, not when/if a company decides they can see or hear it.
