|Just another Perl shrine|
Good sir, no matter how many times you throw garbage in my face, or throw gloves at my feet, I will (well, almost ...) never “downvote” any one of your posts, although I have up(!)voted quite a few. I will never call your name (I don’t even know your name, nor have I endeavored to try). I will not stoop to your ... (Additional text deleted ... why waste the off-topic bytes?)

So, let us, instead, continue to Meditate upon the relevant technical topic.
The intended thrust of this Meditation is: that, although we are now all Blessed(!) with RAM-capacities that are many times larger than any Disk-capacity that we, not-at-all too many years ago, could not dream of in a machine the size of a refrigerator, we still are not (yet) completely divorced from having to consider Virtual Memory. We still deploy to rack-mounted “blades” that ... still(!) ... host a mix of applications whose total (virtual) memory requirements exceed the (physical) memory capacity of the machine.
Well, Perl has “fairly fantastic” abilities to string-together data structures “in memory.™” And, I’m sure that the day will (soon?) come when we truly no longer have to ... (“YAY!!!!”) think about “swapping.”
But (ahem ...) we are not there. Yet.™ And so, alas, we must not get ahead of ourselves, technically speaking. Alas. Not quite yet.™
It is terribly easy to say to ourselves ... too soon, alas ... that “we don’t need no stinkin’ databases.” That the only thing that we need specify, in order to get our hands upon some bit of information, is to specify “a n-bit address,” and to expect to pay no penalty for our impertinence. And, well, we just can’t do that. Yet. (The avant garde architects of the IBM System-38 had the right idea, perhaps, but were a bit ahead of their time ...(?))
So, we (for the moment, “still” ...) have to temper our exuberance, in seeking to take advantage of the goodies that the Perl language offers us, against the prevailing realities of Anno Domini 2015. Knowing that our successors will “have the jolly good laugh” that we did, with regards to such “realities.”
