I guess it's good that they think they're simple enough to use without instructions, since the instructions seem to have nothing to do with the actual software.
It's a garbage collection mechanism. If no one gives a damn about your data, entropy garbage collects it. If you really think your data is so important, you just need to convince human society that it's worth paying the refresh costs on the memory... Shakespeare did it, why can't you?
Presumably. But how accurate is infrared imaging if the surface you're trying to read is essentially the same temperature as the air mass above it? Doesn't the atmosphere get in the way? Or can those things really focus down?
So what happens when the temperature (down to -90C) goes below the sublimation temperature of CO2 (-76C, if I recall correctly)? Does it just freeze out of the air? I'm sure these guys will be heating (and probably humidifying) their air supply anyway, but do they need to add CO2 to keep the breathing reflexes working right?
They're immutable (from reading the article, not previous knowledge) in the sense that "adding" an element really consists of creating a new vlist with the old vlist as its tail; references to the old ones can continue to be used unchanged, and will see an unmutated list.
Rename registers cannot be accesssed explicitly. The processor can use them so that a single named register (say, eax) maps to more than one rename register (say, numbers 7, 13, and 22) in different in-flight (that is, currently-being-processed) instructions. This is useful in the case that you have, say (using ppc assembly because I know it better):
add r3, r3, r4
ori r5, r3, r5
xor r3, r3, r3
(which puts r3+r4|r5 in r5, and 0 in r3; again, this is just an example, and kinda silly). here, r3 is used six times. For the first instruction, it is read in one context, and then written in another (writing always creates a new context). The ori then uses the r3 in the second context, and the xor uses it in the second context and makes a third. So, using tN as temporary (or rename) register N, this is the same as
add t0, r3, r4
ori r5, t0, r5
xor t1, t0, t0
The same could be done for the other registers, of course. The advantage of this is that, because the registers are used consecutively less often, scheduling is easier.
If you're interested in more details, check out (google) Tomasulo's algorithm.
Summary: Renaming is cool. Everyone does it. But it doesn't help you emulate more registers, particularly.

Just give them their own account...
Irony, huh?
I do not think that word means what you think it means.
ME TOO!
Which, of course, can't be done with this device.

What manufacturer would that be?
Um... he's saying that DVD-R stores 5.5MB /more/ than DVD+R. Which is news to me, but far from unreasonable.

Ooh. [forehead smack] Good point. Still must be bloody weird to have dry ice vaporizing under your boots when you step down.
"the temperature plummets to around minus 90 degrees Celsius"... of course, we don't know how that measurement was made...

You've got to be organized if you want to offend everyone!

Nope, an absolute conservative will destroy others to avoid having to change himself.
Way to get the joke...
This sentence has cabbage six words.
I hope the sprinkler system doesn't go off.
Ewww... does it at least come in a plastic baggie?
