I've never heard that before... there is not one vb book which is <1000 sides and everything goes like this.object.has.another.property.than(the.other.object.which.we.talk.about)... and you can program excel & word with it. thats what i think, maybe i should use an excel sheet and do the programming with vb. or is their something like ruby for excel? > >I'm not really into physical calculations but I'm sure you need a fast >language as these things tend to involve a lot of number crunching.

Why is vb not a fast language? I have read statistics who say that you can program in vb 10x as faster than in c/c++. i dont know, i cant c and i dont like it too. /must/ i write an extension to do math in ruby? how fast can java be? depends this not on the browser? and what is RAA? i guess some archive but where can i find it? > > can you tell me the essential differences between java and ruby? what > > can you do in ruby that you cannot do in java? and what about jruby? > > can i combine java and ruby? > >Well, there are of course performance differences (depending on the >application at hand). Ruby is usually more concise and easier to read >(IMHO) because it needs less lines of code. Other than that I think you >can do pretty much the same with both. Is this good?
