Re: [computer-go] Oh no...possible language superiority storm ahead...
I had read couple of articles that Sun was planning new hardware for
gamers that took advantage of Java for 3d Gamers and there were some
discussions at some games discussion websites that big development
houses planned to port several of their games to Java just to test
the grounds.
for Java vs C# I love this site: http://www.javacamp.org/javavscsharp/
When I started to code for a living, I was told that I NEED to learn
C++, so I spent 2 years learning it while I had done mostly C in the
past. What I can say is that C++ can be slower than C if written
wrongly, for sure it seems to me that it is easier to debug by means of
different classes, but I did not notice any speed increase, other than
you have helluva more code to write something simple in C.
Java is the way to go, if I had to start all over again, I would write
everything in Java, I think the old school mentality is to use ASM for
everything, but you really do not need to anymore, hardware are so
fast, why would you even bother trying to save an extra clock cycle
here or there... garbage collection ... Mmmm oh my :)
Just to go back to Games of Go in general, have any of you looked at the
Gaming scene in Japan, Korea or China ? it seems that in Europe or in
the US people worry too much about Languages and Theories and forget
practical issues about programming. I recently purchased Ginsei Igo 5
(i.e KCC Igo) and ran couple of games against many engines (except Many
Faces which I don't own), and it litterally beat all of them. It seems
that the east asian market is finally catching up and surpassing the
European/US counter part ...
Also Vincent: if you ever come in the US, try to lose that attitude of
this is better than this, you won't get too far :) J2EE is #1 currently in
the US, these days you can't find a job if you don't know Java...
Anyways, I'll drop out and will go back into listenning / reading mode
of these "nice" discussions ;)
