when a program asks the OS for memory, the OS assigns a chunk of address space, but doesn't assign memory (physical, virtual, or otherwise) until the program actually tries to use it.
not true. the virtual address space is determined at the time of allocation. otherwise the program won't know where it's allowed to write to. only the physical pages are assigned on actual use (and can be swapped, reassigned, etc).
did you notice what this story was about?
very true. the biggest problem with internet voting is not technological at all. the lack of voting booth makes your vote controllable and sellable.
Windows users also weren't adjusted to having to work under non-admin account.
by using a non-admin account for the last couple of years i learned that the system is much less secure this way.
on windows the only program that could auto update was google chrome. firefox, flash, thunderbird, java, etc, all required manual update checks (which a non too computer savvy user, like my wife, won't do). firefox actually shows that there's an update available when chacking manually, but requires to be "run as administrator" to actually install it.
same problem for the mac. system update checks won't happen automatically in non-admin accounts.
eventually i got pissed of having to update everything manually and switched my accounts to admin.
yes, those paper forms suck.
I could use such a mail account for communications with the government.
i suspect that this is exactly the purpose of the government provided email addresses.
i know enough about EE, trust me. here are some facts for you and all that declared me wrong:
power is not linear with frequency, electrical current is. this is because current flows through MOS transistors only when they're switching. so more switches cause more current linearly. since power is proportional to the square of current (P=I^2/R), it is also proportional to the square of frequency.
all that argued that power is linear with voltage (which is true) should just have asked themselves how voltage and current relate (hint: linearly).
two cores on lower clock rate may consume less energy than one core with fast clocking. energy use is proportional to the square of the clock rate, so it's a matter of tuning to achieve lower power. the only question is whether the slow cores will be fast enough for the important sequential tasks (if there are such at all).
i bet that's the case.
when this kind of "error" appears in elections software, be sure that it's not by accident.
