Comment Re: 911 works over VOIP, DSL uses existing copper (Score 1) 123

80 km pluggable optical modules have been commonplace for 8+ years. POTS "aggregators" (digital loop carrier equipment) originally worked over T1 lines (24 line TDM on one copper pair in each direction, electrical repeaters also supported), were often retrofitted with fiber mux backhaul, and by around 1992 integrated the fiber backhaul function and served larger line counts.

In the '70s-80s in the Los Angeles aerospace realm, it was common for aerospace companies to hire recent BS graduates, then support them for an MS.

My friend and I ran speaker wire between the two houses and used two of these relics for utility and prank calls.

Humans are not spiders. We do not live to instinctively build webs based on inherited firmware.

Thank goodness for this. I had an opportunity to observe a pair of impressively large orb weaver spiders residing for several weeks in the outdoor corners of a picture window.

I read a little about orb weavers, and learned that females frequently cannibalize males after mating, that they frequently mate with siblings, and that cannibalism of males is a little less frequent in this case.

In Plano, Texas maybe 1992, a dinner group of us took a shortcut across a vacant lot. The ground was littered with numerous Robitussin bottles. In around the same era, I was in a drugstore in Eureka, California buying clip-on sunglasses, when I overheard the pharmacist say "Susie, I can't sell you any more cough syrup on credit, until your mom pays the bill.'

My experience from some years ago using the low-rent combination of a Bialetti stovetop "espresso" pot and whirly-blade grinder, was that Sulawesi Kalossi tasted like Comet cleanser, but the same grind was excellent when brewed in a French press. These days, I go to a local shop with a real espresso machine and a good coffee supplier. This region is usually cool and damp, but when a streak of dry weather arrives, the espresso quality worsens: fast bitter shot with little flavor body, and poor crema, unless one of the more careful baristas adjusts the grind and packing,
