  • Commented on What else can you do with a Big Dumb Booster?
    Take off from a US base that housed the brigade, with most hardware already onboard? Loading the fuel is a bigger issue. Equipment degrades over time especially when not used. And military equipment more so than many civilian things since...
  • Commented on What else can you do with a Big Dumb Booster?
    Depends what you drop etc. And quarter of a million is probably overkill for what I had in mind. Here's a rough idea, you could carry battalion of Apache helicopters in one go. Do you understand the size of the...
  • Commented on Evolver
    Yep. Wild pigs are such a problem in places like Texas that it's pretty much legal to hunt them year round. http://tpwd.texas.gov/huntwild/wild/nuisance/feral_hogs/ Of course PETA has a great solution. http://www.peta.org/blog/refuges-sanctuary-feral-pigs/ or NOT http://txagtalks.texasfarmbureau.org/peta-wants-no-feral-hog-left-behind/ But at the end of the day...
  • Commented on Evolver
    cattle and horses are less prepared to go feral if you abruptly remove all human intervention. As someone else mentioned horses seemed to have shown they can go feral based on the last 500 years of history in the US....
  • Commented on Writer, Interrupted
    Because (no matter what "Red Storm Rising" implied) if the CCCP headed west the US/NATO/whatever felt there was a good chance they could not be stopped otherwise....
  • Commented on Writer, Interrupted
    Are there any cold-war babies out there who don't have nuclear nightmares? Yes. Many and likely most of them....
  • Commented on Writer, Interrupted
    My default mode most of the time is my phone is on vibrate. And I have an Apple watch with the sounds turned off all the time. And it only vibrates for events for which I want to be interrupted....
  • Commented on Writer, Interrupted
    The wonder of email is you don't have to look at it, yet. One of the first things I do when dealing with a new device "for me" is turn off email alerts. Except for a few people who get...
  • Commented on Writer, Interrupted
    My wife wants silence when concentrating. I can't stand silence. When it is too quiet every little cricket outside distracts me. So I tend to have TV cable news on and/or radio. When on at the same time on low...
  • Commented on Sad Trombone Exoplanet Reality Check
    a (real) suntan is protective, to some extent Not really. A suntan amounts to an equivalent of 2-3 SPF Hmmm. One data point. In my foolish youth I mowed fields in the summer typically wearing nothing but shorts shoes and...
  • Commented on Sad Trombone Exoplanet Reality Check
    At some point I expect it will be possible for quadriplegics to use VR, which will mean you can just immerse yourself in VR let your body decay into a puddle (a la Wall-E). I wonder more about Surrogates. http://www.imdb.com/title/tt0986263...
  • Commented on Sad Trombone Exoplanet Reality Check
    I looked at basic logic things a bit (to brush up, I haven't been using this knowledge in years), and while it's only two relays (or transistors) to make a NAND gate, making a half-adder is five NAND gates, and...
  • Commented on Sad Trombone Exoplanet Reality Check
    No. There are a lot of people who can't wait to "retire" and watch TV all day. When not sitting in a boat fishing. Or attending concerts in Branson. I can't imagine that "retirement". As to your description. For a...
  • Commented on Sad Trombone Exoplanet Reality Check
    I wasn't trying to say people should not "retire". You had a plan and implemented it and I assume you're happy. Great. I just can't imagine that I would "retire" and go fishing every day and sit around watching TV...
  • Commented on Sad Trombone Exoplanet Reality Check
    Sorry. I was reading the comments while in real life are dealing with burnout of my wife dealing with her mom and realized I've never heard of anyone addressing this in their space colonization operas. Dementia in all it's variations...
  • Commented on Sad Trombone Exoplanet Reality Check
    The currently most practical key to reducing and slowing dementia is staying physically and mentally active (both are important). Agreed. Studies have indicated the most likely cause of death for people in white collar engineering type jobs is retirement. But...
  • Commented on Sad Trombone Exoplanet Reality Check
    I think that it would be fairly easy to get the former up to 70%, which would also reduce dementia ("use it or lose it", remember?), I think you're wildly optimistic. One of the biggest problems with dementia is...
  • Commented on Sad Trombone Exoplanet Reality Check
    dementia Has anyone thought of what to do with the old folks on these missions? Says he who is dealing with (and recently dealt with) an aging parent in law who's more and more impossible to deal with in a...
  • Commented on Sad Trombone Exoplanet Reality Check
    It also seems comparatively hard to even find SF stories that are set in our own solar system. There are obviously a number of high-profile examples recently, but they stand up against the huge mass of people zipping about from...
  • Commented on Reality is broken
    (It's worth noting: the unsuccessful ones do tend to be the ones who were largely voted in on their photogenic looks. Strangely enough, looking pretty and manipulating people based purely on your appearance isn't a viable professional advancement strategy in...
  • Commented on Reality is broken
    I am surprised that you would have wanted Bush to "finish the job" as regime change was not what the UN and the UK signed up for. Isn't American hubris a sore spot for you? (It is for me and...
  • Commented on The iron law of development
    I grew up in a glacial moraine in southern New England where the winter freeze line was not very deep. Hmmm. According to this: https://nsidc.org/sites/nsidc.org/files/images/NA_permafrost.jpg it's 3 to 6 feet and more in Maine. Reading this post I suddenly realized...
  • Commented on The iron law of development
    Indeed. I'd go so far as to say that handwriting notes is a form of doing (information goes into your ears, gets filtered by your brain, the output to your hands), and that replacing that with staring at lecture notes...
  • Commented on The iron law of development
    I think a better indicator is to look at when the standard ammunition changed, rather than the introduction of new variants of rifle to use it. I have a memory from Ken Burn's US Civil War series of a mention...
  • Commented on The iron law of development
    But if your mother's step mother is still alive, ask her. Seems unlikely. But women wore dresses or skirts for farm chores throughout the middle ages and beyond. I'm pretty sure, although it's not a particular sensitive topic, female slaves...
  • Commented on The iron law of development
    Let me phrase it differently. Virtually all women wore dresses. But wearing pants as a practical matter became way more common in the 30s and later. This was a time where many people who were not homeless maybe had only...

    Nuts. Electric CARS....
  • Commented on The iron law of development
    Regarding why things took so long to develop a lot of it comes down to the incremental improvements to the various bits that make something up taking time to develop. Similar to semiconductor designs. Every years since the early 60s...
  • Commented on The iron law of development
    In the 1930's dresses were pretty much the only choice for 99% of occasions. Always with a hat if you were outside of course, for most of the decade with a belt at the waist and some crazy frou-frou around...
  • Commented on The iron law of development
    in addition, please do not confuse "labor saving" with "time saving". Many time newer tech didn't save labor or time. But allowed people to avoid the disgusting older way of doing things. Even dug up a septic drain field to...
