St AJ :	(08 September 2010 - 04:42 PM) @jayhawk9999: the final season aired in 1995. If you were 18 now you'd have been 3 at the time. Reruns don't count.
moltom :	(08 September 2010 - 03:45 PM) Except by length.... that's the A340-600
moltom :	(08 September 2010 - 03:44 PM) Thanks guys but she said she said you can't win a debate with definitions.... So I guess I win! Because there's no way she can prove the A330 is larger! A380 largest in all means!

WombatBoy :	(08 September 2010 - 03:39 PM) The longest plane is the A340-600. Largest would be the A380, yes.
moltom :	(08 September 2010 - 03:35 PM) Hey guys, I was looking in my LEGO™ club magazine and there was a question that my sister said was true but I said it's not! Heres the question: the worlds largest passenger plane is the airbus A330, it's as long as... then the answers... I said it's a lie! the largest plane is the A380! She said not! Is this true?
Jayhawk9999 :	(08 September 2010 - 03:29 PM) That's not true, the average college freshman was about 7 when it went off of the air; old enough to remember
St AJ :	(08 September 2010 - 02:02 PM) the average college freshman today was a toddler when that show went off the air....I feel old now
St AJ :	(08 September 2010 - 01:59 PM) great, now I'm getting flashbacks to the giant stone head from Legends of the Hidden Temple

Throttle And Pedal Joystick Not Recognized In Linux trying to use CH Pro Throttle and Pro Pedals

I'm trying to use the following setup with X-Plane 8, on Linux:

CH Fighterstick Pro
CH Pro Throttle
CH Pro Pedals

when I enter the joystick calibration screen, the X and Y axes of the Figherstick are regonized correclty. But none of the other two joysticks are recognized at all.

moreover, it seems that the third axis on the fighterstick isn't recognized either. and, none of the buttons on the throttle are recognized either.

it seems that only the very first joystick is recognized by X-Plane, and in a rudimentary way - with only X and Y axes.

how could X-Plane be made to recognize joysticks properly on Linux?

I found the cause of the problem myself: as X-Plane is a 32 bit application, and I'm running a 64 bit system, the joystick controls need to be mapped to 32-bit space. Unfortunately this is not done by the kernel. This issue has been raised a number of times:

http://readlist.com/lists/vger.kernel.org/.../28/144411.html

http://www.brettcsmith.org/wiki/wiki.cgi?a...mputer/Joystick

but still to this very day the kernel is not patched appropriately. You can find patches to kernel 2.6.11, 2.6.15 at the above links. here's a patch that works on 2.6.22:

I also posted the patch to the linux-kernel list, see if it gets included in subsequent kernels.
