Howard Bloom: Climate Change Is Nature's Way

We've been deceived by a stroke of luck. In the two million years during which we climbed from stone-tool wielding Homo erectus with sloping brows to high-foreheaded Homo urbanis, man the inventor of the city, we underwent 60 glaciations, 60 ice ages. And in the 120,000 years since we emerged in our current physiological shape as Homo sapiens, we've lived through 20 sudden global warmings. In most of those, temperatures have shot up by as much as 18 degrees within a mere 20 years.

How to tell if your CPU is 32 or 64 bit

If you're just interested in whether the currently running system is 32 or 64 bit, then 'uname -m' will tell you either i686 or x86_64 depending on whether you have 32 or 64 bit cpu.

Unfortunately if you want to know if the system *could* be 64 bit, you need to check the cpu flags. The flag 'rm' means its 16 bit, 'tm' means 32 bit, and 'lm' is 64 bit.

`grep flags /proc/cpuinfo`

rm: real mode, 16 bit

tm: transparent mode, 32 bit

lm: long mode, 64 bit
