[PlanetCCRMA] GUI Issues with Dell Vostro

[Jeff Sandys]

As I understand, the Real Time (RT) kernel enables low latency performance.
RT kernels allow 'important' tasks to preempt less important task on a
regular
basis, where a vanilla kernel completes the less important task first.  So
you
should use the RT kernel for audio work, but you don't need to set the
latency
to the wall.  Since layering a recording is a common task the recording
apps
compensate for the buffer size.  The easiest way to tell if your latency
settings
are a problem is try it.

OT
The Lunar Module Computer is an interesting study in real time programming.
The Waitlist ran the highest priority interrupt while the Executive program
ran
every 20 milliseconds and set the Waitlist priority order.  6000 feet above
the
lunar surface, 6 minutes before touchdown, the yellow overrun light came
on.
The radar antenna pointing task was causing "xruns", mission control
recognized the code and told the astronauts to continue.  Each overrun
caused the computer to reboot, the descent engine steering and throttling
tasks had top priority.
