Interesting points about the early DOS days wrt to ‘stack’. Hmmm, maybe we’ll see pejorative semantic development at some future point — job description — wanted a full stacker, but overflow stackers need not apply. :- ) Hope you are doing great!

Nothing of this earlier, low-level understanding of ‘stack’ appears to remain in the usage ‘full-stack programmer.’ Indeed, since a full stack came right before stack overflow and consequent program crash, we might construe a full-stack programmer to be one given to risky coding, or one insufficiently attentive to deeply recursive routines. …

desert rested deters

I was struck by what a forbidding landscape these word suggest:

Erosion and geological tearing have created a fissure through which rapids tumble between granite walls. This feature deters all but the hardiest traveler, who, once he has rested in the parched desert beyond the canyon rim, may well reproach himself for having been an ingrate midst the noise and spray of the torrent below.

And in fact we often use -age in precisely that kind of allusive way. We speak of ‘teenage music’ not to describe music composed 13 to 19 years ago, but rather music that appeals to adolescent tastes. ‘Middle-age spread’ references the fact of the expanded waistlines of many people in their middle years; it doesn’t mean the adipose tissue itself is 35 to 55 years old. So we could construct a formalism in which we use aged to mean how old (‘…died yesterday at Brighton, aged 91′) and age as a pointer to some remote object. Well, we could, but I doubt anybody would start talking about moderately-aged men in shorts…
