[NTLUG:Discuss] Need some inputs on porting.

[Stephen Davidson]

Hi Harshal.

I really have to ask,
for complete platform independence (for Linux, Solaris, 32bit, 64bit, etc),
I really have to ask, why not Java?
Now a days, Java is just as fast (and in many cases is faster) than C/C++.
And it has all the features you are looking for (at least as stated so
far in this email).

Just wondering.

Regards,
Steve
