Comment: Re:Stacked RAM isn't anything new. (Score 1) 110

I have a memory card from an original IBM PC from 1982, which has stacked memory chips. In fact, each pair of chips has ALL of their pins wired to the same contacts on the PCB. Although I have been unwilling to take apart the board to verify, this leads me to believe that the chip on top and the chip underneath are different. I'm guessing one of them has an inverter on an address line, so it will respond to even addresses, while the other responds to odd addresses.

Really? The moon orbits the earth. Is it eclipsed by the earth 50% of the time? Of course not. You're only thinking about satellites in -low- earth orbit, which are shaded by the earth basically during half of each orbit. Put the satellites in very high orbits (geosynchronous itself is pretty high), and they are exposed to sunlight far more than 50% of the time. Heck, put a satellite in a polar orbit and for much of the year it can be exposed to the sun -throughout- its orbit.

That still means at any given time 1/2 the panels aren't doing anything useful. It also means on every lunar day the panels go through massive temperature transitions from incredibly hot to incredibly cold.

Instead, you could place a ring of panels in high orbit around the earth and have -all- of them working nearly all the time. I guess there might be a tradeoff due to the need for microwave transmitters on every generating satellite (since wiring together sets of panels many kilometers apart in earth orbit is probably not feasible).

Some of us care about that $10 a month. In fact, I didn't get basic cable bundled with my internet until it actually -dropped- the cost of my internet (net cost of basic cable was actually -negative-).

But what happened next? Comcast decided to switch basic cable from analog to digital to save bandwidth. (Ok, no problem so far - that's actually a good idea). But what did they give basic cable subscribers then? A tiny box which converted the digital signal to 4x3 Standard Definition NTSC television (the old Channel 3 connection). In other words, crap. I could hook up an antenna to my TV and pull broadcast TV in 1080p HD, but the cable company puts me back in the 90's. You bet your ass I cared about that $10 a month. If adding basic cable to my internet connection cost me even one cent I wouldn't have been happy.

That was really the weakest point of that story and really completely unnecessary. Considering that Doctor Who established that a Weeping Angel is a -stone statue- that can't move at all if anybody is looking at it, it makes no sense at all. First, the Statue of Liberty is not stone, and second, is there actually any point in time where -nobody- at all is looking at it?

That's quite a generality. I've been to my daughter's high school and the teachers there don't appear to be lazy in the least, AND they seem to be leveraging technology in sensible ways. For example, the way my daughter can log in to a school web site and see every day's lessons and homework assignments.

Computers can figure out all kinds of problems, except the things in the world that just don't add up.
