We've had very strong interest from delegates on the LCA2014 chat list in attending the Perth Observatory for a night-time stargazing tour. Everyone needs to make their own booking, and bookings need to be made soon as spots will fill up quickly. The observatory doesn't have an online booking/payment system, so you'll need to call them with your credit card details to reserve your spot.
+
They then did another one. This was mentioned at BD 58, but no one else
 +
was interested. I have not reviewed it. We do not use it.
  
Bookings can be made by phoning (08) 9293 8255 between 8.30am and 3.30pm (AWST, 3 hours behind AEDT), Monday to Friday. Tickets are $38 for adults, $28 for children/concession card holders.

The logistics of getting everyone to the observatory is possibly going to be tricky. Getting there by public bus would take a little over 2 hours, which almost certainly rules that out. The only viable options would seem to be car-pooling (locals and/or sharing hire cars and/or sharing cabs). The observatory is 38km from UWA. If enough people book for the observatory ~and~ if we can coordinate things well enough, it may be possible to book (a) mini-bus(ses) for the evening if we can find people with the appropriate licence amongst delegates, or we may be able to book a charter bus if we get 40+ people going. But that all takes organisation and (most importantly) the ability to collect money in advance - which usually proves difficult, at best.

Software disclosure is more important as software can be used to change

CMOS CPUs are clocked much faster than thermal limits permit so they
must slow down as they heat up. When processes have yielded the CPU
stops and cools down. This means that the CPU can run much faster in
bursts than it could in continuous operation. This mode of operation
was first used in CMOS mainframes where a valid process will yield for
IO. Something similar was done in calculator key-press, get, process,
update display and then sleep to save battery power.

Linux has the ignore_nice_load feature which stops nice jobs breaking
power management that must now be regarded as essential. Linux does not
usually stop, but it does slow the CPU down. This cools the CPU and
allows it to burst up to full speed when priority jobs become ready.

When you are running stuff like https://boinc.berkeley.edu/ you may not
want it to slow down your apps. Running it nice alone will not prevent
your apps from being slowed down. You need to give your CPU a chance to
