  • Commented on Ask me anything!
    Two notes: 1) The 286 had full protected mode segmentation, it didn't have paging (that showed up in the 386). It was quite possible (and they existed) to write an OS that took advantage of the segmentation. In fact, I...
  • Commented on Story time!
    AIUI the original proposals for TCP/IP in the mid-80s included end-to-end RSA encryption—until the NSA realized they wouldn't be able to snoop on the business and academic mainframes and corporate workstation networks using it. This was the era that gave...
  • Commented on Story time!
    (As witness RMS's dismay at having to set a password on his user account at MIT in the mid-80s.) Stallman's a smart guy, but he's locked in an ivory tower and really doesn't (or didn't) understand the real world is...
  • Commented on Story time!
    “I had tentative plans to do [an essay] for INVISIBLE SUN, on the history and design principles of the Commonwealth's attempt at computerizing—with 20/20 hindsight based on being able to see everything the USA did wrong through the year 2020...
  • Commented on Story time!
    Actually, I'd suggest that the biggest problems with electrical are the insulators for the wires (and/or the porcelain for the insulators if you want to run bare wires on posts) and the lubricants for the moving parts. It would also...
  • Commented on Story time!
    There is a big difference between making ICs for modern computers (billions of transistors) and stuff you need to make a washing machine work (thousands of transistors). Even engine computers can be done with "only" a million or so transistors....

  • Commented on CMAP #16: Book Title Blues
    https://www.amazon.com/slp/hotpoint-drip-pans/dsp6745qzj728vv I remember you do have to get the right kind of drip pan depending on how the element connects to the stove. Hope it helps :)...
  • Commented on CMAP #16: Book Title Blues
    It used to be that you could buy the drip pans at the super market, but it has been 10 years since I had to worry about that (and we had an "off" brand as well, actually it was quite...

  • Commented on Social architecture and the house of tomorrow
    With device to device charging already supported (see Samsung Galaxy 10 ads), wireless power transfer will get more efficient. As to how? I don't know, meta materials, phase array antennas, something awesome (see for instance: https://www.teslarati.com/tesla-patent-more-efficient-electric-motors/). And it will not...
  • Commented on Social architecture and the house of tomorrow
    Seeing all these posts about wall warts and switches, etc. If wireless charging takes off (and it has a good start), I would envision lots of wall space that has wireless chargers behind it, just put your phone (or other...
  • Commented on Social architecture and the house of tomorrow
    It must be a family thing. Amoung my four grandparents, at least the families for two of them didn't stay within 100 miles of where the grew up, at least as far back as a couple of hundred years (which...

  • Commented on Deaths and Deadlines
    Your timeline is more than a bit off, the movie "Star Wars" premiered after the Enterprise was doing its first drop tests. The Reagan-esque Star Wars program was well after the Shuttle went into use. I think you are a...
  • Commented on Deaths and Deadlines
    Great idea. I'm glad I thought if it at post 149. ...Sorry about that. Still a frightening thought.......
  • Commented on Deaths and Deadlines
    DC-X crashed because the technician forgot to wire up one of the leg release actuators. It was supposed to run more tests, but it was an unpopular project, so it stopped there. (If it was popular, they would have just...
  • Commented on Deaths and Deadlines
    On the flip side, we could interpret GRBs as just shots fired in interstellar wars, and since they are so focused, we only see a small percentage of them. (I zap your solar system, HA HA HA!!)...
  • Commented on Deaths and Deadlines
    If the others "out there" are indeed working on a different time-scale to us, we might see them but not immediately realize it. Take, for example, Gliese 710 ( https://en.wikipedia.org/wiki/Gliese_710 ) it will be passing by our star in a...

  • Commented on Crawling from the wreckage
    Since that article is from 2014, I guess nobody cared backed then.......
  • Commented on Do my Homework
    One blindspot I see in SF that tries to cover more than a few thousand years: Stars move. They move to the point that in a million years Gliese 710 will be close enough to disturb our Oort cloud. In...
  • Commented on Canned Monkeys Don't Ship Well, the Remix Version
    So, there is always the ultimate starship (Earth), and slowest STL (do nothing). Just wait for another star to get close enough. According to wikipedia, Gliese 710 will approach the solar system to within .2 light years in about 1.2-1.3...
  • Commented on Canned Monkeys Don't Ship Well, the Remix Version
    Some of these are obviously solvable: Use baffles so the water doesn't slosh. Land the propellant plant first, then land other stuff when that works. Also, I think the attitude of using more (or more complex) technology to solve these...

  • Commented on Why I barely read SF these days
    One idea for charging EVs: Use wireless induction charging, and allow the car to have the information to negotiate paying the bill. Possible results: When a installed on a street (or parking lot), your car just charges, no muss/no fuss....
  • Commented on New Book Week!
    I wasn't expecting you would start from 1900 level. You would start with either a very modern nuclear or solar generator for power, modern construction materials for the initial colony (to build the first green houses and living quarters), plus...
