So some jew tried telling me Java was faster than C++ and I was like wtf
which is faster sirs, Java or C++
this is the post he made:
"I think that this will be one of the first Linux kernels to be written in Java, and should ensure a massive performance increase as well as Java runs 3-4 times faster than C."
the first thing that got me lolling was "first linux kernels"
Run-time optimizations should theoretically be able to manipulate Java code to run faster than C++ (avoid or at least short-circuit dispatches that always go to the same place, eliminate bounds checking when offsets are known valid, etc).
There's also hardware Java stuff of some sort on a lot of mobile processors; dunno if those will ever make it to the desktop.
theoretically

Maybe faster, but how much space overhead is there? A considerable amount.

The speed gain is theoretical so we've got a language with a speed penalty and space overhead = SLOW AS FUCK. A Java implementation that achieved this actually exists only in your dreams

Really, who the fuck cares about space overhead? If it does what you want, and takes 30MB instead of 10MB, big fucking deal.
The java libs blow the shit out of anything C++ has to offer, and you crash out with exceptions in Java far less than you corrupt memory in C++, making it a ton easier and faster to develop for.

I actually look forward to the day when a desktop OS will be released that's built on a non assembly-like language. I think it'd be stupid to do it in Java, but C and C++ are way too brittle and nonreflective to use as your core services.

huh? Is there anything that truly succeeded as a non C-based OS for the desktop platform? Sure there were Lisp machines and such, but those don't count as desktops.
