If you are intent on using fourth try gfourth under interpreted computer
languages (universe). I however see the word interpreted and am
reminded how slow they are in comparison to compiled code. If you know
machine language and are willing to hand optimize C++ code it is hard to
beat for speed which I recall was one of the reasons you were looking
for fourth.

Python and C++ go hand in hand Python making writing code much easer
than in C but C code can be used in Python. Java++ is almost like C++
with the advantage of web based applications.

If I needed speed I would buy as much computer as would give me the
speed I was after, i.e. multi processor, much more memory than system
requirements to keep swap to a minimum, and I would organize on many
hard disks my information to reduce indexing speeds, and of course the
use of dedicated video processors when needed.

My need for speed is minor, I use a minimum system and notice that in
the few years I have been hooked on Ubuntu the system is running
slower. To me the trade-off is worth it because I know more people by
the day are jumping on the Linux band wagon. The more users switching
to Linux, the better the hardware support from the manufacture will be.

Because I like what Ubuntu is doing to entice new users to the Linux
platform. I feel it is a folly to reduce overhead for the sake of
speed. I feel hardware is the ticket to faster computing. To a large
part, hardware manufacturers will supply drivers, or better information
about their equipment to Linux developers as the user base grows and
demands it, so Ubuntu is on the right track in their development strategy.
