The second query can be formulated in a way to avoid generating the duplicates. That's a simple exercise in Boolean algebra. And the search engine can take advantage of this "no duplicate" filter to optimize the search. Even in the absence of such optimization, you can optimize the network traffic by eliminating the need to send the duplicates back to the caller once more. -- Lee Sau Dan §õ¦u´° ~{@nJX6X~} E-mail: danlee(a)informatik.uni-freiburg.de Home page: http://www.informatik.uni-freiburg.de/~danlee

Why should I bother to check whether it's equivalent to my ORIGINAL form? That should be something that the computer is doing for me. So, with a CLI: I am the master and the computer is a slave. with your GUI: I am the slave serving the needs of the computer. Smart people would know which choice to take. -- Lee Sau Dan §õ¦u´° ~{@nJX6X~} E-mail: danlee(a)informatik.uni-freiburg.de Home page: http://www.informatik.uni-freiburg.de/~danlee

To learn a language, exposure is extremely important - it's not enough to just learn it, one also have to use it and practice it with different speakers. I think I also learnt English at age 12 in the school, but I had some exposure before that. I remember the first English I learnt was "run game", which I was frequently entering at the command line ;-) Some years later also I learn German in school. Since I've almost never had any use of my German, I'm usually telling that I can't speak nor understand German - and that's pretty much the truth. > blmblm> matter.

Though I cannot dig up any references at the moment, I've read several times that it's easier to learn languages the younger one is. Some studies have concluded that adults learning languages are using another part of the brain for learning the new language. As for myself I've tried learning Russian and Spanish in adult age, with very little success. Almost all foreigners I've met who have learnt my native language speak with lots of accent and minor grammatical mistakes. One of my teachers at the gymnasium was from the east Europe, he had been living here teaching at the same school for around 30 years, and still he had a very distinctive accent - though, rumors had it the accent was just a gimmick, and that he sometimes was seen in the public speaking without any noticable accent. I don't believe that rumor :-) Bilingual children can learn two languages amazingly fast. I was hanging around on a mailing list for bilingual families for a while (but finally gave up, too much activity). According to the experience (expressed by several people on the list), quite often a 3-4 year old child has already started bypassing adult non-native speakers of a language, like if the father if trying to speak the language of the mother, the child can often start correcting mistakes. -- This signature has been virus scanned, and is probably safe to read Tobias Brox, 69?42'N, 18?57'E |
