From the man page:
-fdelete-null-pointer-checks
Use global dataflow analysis to identify and eliminate useless
checks for null pointers. The compiler assumes that dereferencing
a null pointer would have halted the program. If a pointer is
checked after it has already been dereferenced, it cannot be null.
In some environments, this assumption is not true, and programs can
safely dereference null pointers. Use
-fno-delete-null-pointer-checks to disable this optimization for
programs which depend on that behavior.
Enabled at levels -O2, -O3, -Os.

Yeah I really should have gone for the switchmode solution and saved a few microwatts. In my day sonny we were glad to have zeners. I had to walk all day in the snow....up hill...oh stuff it.
Do you really think a voltage regular only saves a microwatts compared a zener?
You might need to build a dumb USB power supply for it though. How about a 9 volt battery, a resistor and a zener diode?
How about that's extremely inefficient. For an additional $0.50 you can get a voltage regular or DC-DC converter.
Come on, I'm on the digital side of EE and I know better.
What's really important here is that the key would be kept in SRAM(CPU Cache), not DRAM(Memory). With DRAM the stored bit is stored in a capacitance and in SRAM the bit is stored in a latch(usually a D-type latch from what I understand). I would guess that it's harder to freeze SRAM and keep the bit in place.
are you aware that in 5 years system i will be dead (it's set to merge into system p) and system z will be rolling out z11?? I work at an IBM datacenter and system has the fewest amount of machines
one also has to consider that bandwidth is particularly important as delay is when considering VoIP (this is why when you sniff your skype call all you see is UDP packets -- no TCP packets) And since BT makes latency increase it is especially bad to use while using VoIP... this is one of the fundamental problems (and strengths) with thte internet -- it is a packet switched network, not one of direct connections
Suppose that border guards can't access the information that is kept in your mind, so if you encrypt all your data, and store the password in your mind (i.e. you remember it) Could you protect your privacy this way... or at very least you lie and say that you forgot, it would be impossible to prove othwerwise.

This year's Smart Radio Challenge is quite similar to this initiative http://www.radiochallenge.org/09SampleProblem.html
