I don't think this strategy is that good. Something similar has already been tried in switzerland, and failed (sorry, I don't have a link to post right now).
First of all, it would be impossible to track all possible hostnames to block and every user for example using a proxy or surfing at school would have access. Therefore, it would be technically difficult.
It could also be dangerous: who (and how) decides what to block? Would people like to have their data filtered by ISPs?
I think that other solutions have to be found to solve this kind of problems (child porn and other illegal activities on the net), like for example an international task force to investigate and find out where these sites are, close them and send responsibles to jail...
In Zürich (Switzerland) WLAN access point have been installed on the lake side, in order to provide wireless internet access to people having a rest in the various parks around.
The access is basically free (you just have to sign up to get a free account).
I still remember the first 3d hardware, and I still have a pc running with a matrox mystique and a 3dfx voodoo I...
I had been involved in demo coding for a while as an high school student and we had managed to implement a 3d software engine which was working really fine, at higher resolutions as well. The most important thing is, we were having lot of fun.
Maybe I am getting wrong now, but I believe the first version of quake came out without any kind of 3d acceleration (everything was software made, they just wrote an almost perfect code...)
But one day, well, 3d hardware came out and the whole thing wasn't funny any more. In the beginning it was very difficult for a single person to develop something decent using 3d hardware (because of a lack of good docs), while big companies started to produce lots of games using 3d acceleration, which were very badly optimized.
Well, I don't know, I still think that 3d acceleration took away a big part of the intellectual work due to the optimization process of code in games. Of course there were and there still are exceptions.
I think one good way would be to generate a completeley random password (i.e. creating each letter as an outcome of a discrete, uniform random variable, of course each letter should be indipendent from the other one). I think the biggest problem would be to produce true random numbers (pseudo random wouldn't be good at all).
Look at page 3 of their paper, they published a slightly adapted version of the IOCCC Contest winner of '98. They of course adapted it to the paper, therefore I suppose it lost most of its obfuscated features:).
And in the references list on page 37 you can also find a link to http://www.ioccc.org...
Ok, guys, let's suppose NSA can crack big RSA keys, then they would have:
1. proved the P = NP, and break keys in a decent time, or 2. managed to build a quantum computer, or 3. found a big mistake in the whole mathematical logic theory, so that most of the proofs in complexity theory are somehow wrong, or 4. let a linux cluster crack rsa and in the meanwhile acclerated the whole universe to the speed of light, and let it come back...
Please guys, trust open research!!! A mathematical proof stays the same for everyone!
As many have pointed out, it is just a nice random number generator. There are other ways (for example you can use radioactive materials and take the time steps between relase of various radiation).
The One-Time-Pad is information-theoretically proved as a safe method (the proof is even easy:) ), that is without the key, the encrypted text does not give you any information about the real text. For example, with a bitmap of the lava lamp, you can use the single bits as a key, and with a simple xor-operation you encode/decode the text...
There *must* of course be a safe method to transmit the key (and right now quantum cryptography is giving us some nice methods to do that)
But the One-Time-Pad isn't new at all... and still about factoring: oh well, there's already a nice algorithm to compute Eluer's phi function in polynomial time (and this would break RSA..), we just a need a quantum computer to use it... (see: Schor's Algorithm)
As far as I know, the movie will be shown at the Locarno film festival in the following days, and that sould be the international premiere. Locarno is located in southern switzerland, and as a giant (maybe the biggest in europe) outdoor-movie thather (around 10'000 seats). So if you are spending your holiday here around... You can certainly find more information at this url
I agree with you - didn't read your message first, I posted something similar here below (about Oberon) [don't post as anonymous coward, some messages have to be moderated up!:-)))]
IMHO., I am at ETH too, and Oberon-2 is nice:-)

A few European Universities use Oberon - it's a nice language to learn programming. More at http://www.oberon.ethz.ch
Is it really so difficult to switch between different languages? C'mon... you are spending time at school not for learning somewhat that will become old in a decade or less (or more, it depends;-P). I find it more important that you can learn how to build complex and correct algorithms in each situation. For example, once you've learned how to implement an AVL Tree, well... I do not find it too difficult to implement something similar on other languages. After all, you have book for this (reference manuals of different languages, I mean). In every modern programming language you have similar structures. So, if someone wants to teach Java, or C++, or Oberon... i really don't care, it just matters that the language is modern.

... it just can compile different programming languages in virtual machine code (that is it's languange indipendent) - for example at ethz we are developing Lightning Oberon - which is a release of the Oberon language for the.NET technology, see http://www.oberon.ethz.ch/lightning/

CS vs CIS
·
· Score: 1
I am CS student at ETHZ in Zurich and I really enjoy studying stuff like maths, algorithms, complexity, logic and so on. Something similar to CIS can also be studied at Zurich University. The trend is mainly to try studying CS first, and people who don't manage to pass the exam usually migrate to CIS where they often do not have big problems in programming oriented courses. Many companies here do not make big differences between CS and CIS students and I think that your choice should really depend on your goals: if you plan to work in big companies like banks or industry you shouldn't study CS. CS is cool if you want to do for example research. If you like to hack, well, there's EE as well. I don't even find math in CS courses that difficult: I've always loved math and I often go to lessons for mathematicians so I really realized that maths for computer scientists is really easier.
Have fun
I think everyone here who is less than 30 sends SMSs all the time. I receive tons of them everyday, even from people I really do not know. Broadcast messages coming mainly from the cell phone companies exist as well (but you can disable them), and many services are available through sms. During my last exams everyone had to show his own cell phone to the professors, so that they could see whether it was turned off or not and so that we couldn't be able to receive messages during the examination. It's not such a pain to type in your own message, because of the fact that new phones provide nice solutions to this problem: Nokia phones have an internal dictionary, so that you don't have for example to press the "2" key twice to have "b", you just press it once and when you finished typing that word, the phone looks up the various matching words. Ericsson provides a "chatboard", that is a small qwerty/qwertz keyboard that you can plug in to type your own messages.
I must say, as Italian-speaking, that the translation made by Babelfish sounds (as usual) a bit funny. I really don't manage to understand some things, even though I'm Italian. But it's OK, glad to see something familiar on./ . I even didn't notice the first time I was reading it...:P
This is what I get from home.verio.com... "The most likely cause of this problem is that the server is not currently running. Verify that the server is running and restart it if necessary." Do they need help?
Teletext is a way to transmit different data over an (analog) TV channel. You can send up to 800 pages with text and some kind of graphics, but this system is mainly text based (there now newer standards which let you send more complex data, but they aren't so widespread). On teletext you can find for example news, weather informations, sport results, timetables of airports and railway stations, tv programmes, closed caption, and so on. Almost every tv station in Europe has now got its own teletext.
I was just wondering whether there could be a better solution than RDS. I find it a bit too limited, in fact you can just trasmit very few bits of data. Seeing what is now possible with digital TV, I think there could be better solutions and digital radio is now becoming a reality in most parts of europe

Yes, sorry, in fact you are right (I got lost in writing something ironic). As far as I know it is just *feared* that factoring is not P.
