  1. Re:Tacking around the moon on LightSail Wakes Up After Silent Spell and Tries To Spread Solar Sails · · Score: 1

    Actually, from what I understand it's the resistance of the keel that lets a sailing ship tack into the wind. The keel is long and thin seen from the front and wide and flat seen from the side - so in one sense it is water resistance, but its resistance of sideways motion vs. front to back motion. A flat bottomed rowboat can't tack even if you add sails - no keel. Learned that from Peabody and Sherman a few centuries ago.

    Thank you sir! That was a well composed, thoughtful, informative and thorough comment - whatever are you doing on Slashdot?

    I'd like to thank you for your service too.

    BTW: Great Slashdot username - was that your handle as a pilot?

  3. Re:Security is a process - not a tool on Tim Cook: "Weakening Encryption Or Taking It Away Harms Good People" · · Score: 1

    As one old hand on /. to another - hats off to you sir if even half of what you said is accurate (and I have a suspicion it is). It was once called civic duty, but is sorely missing today.

    Nothing gets peoples attention like the unmistakable "crunch-crunch!" of a shotgun being primed, I imagine. I have no guns myself, but I would still step out with whatever was at hand if a situation similar to the ones you describe above occurred.

    It's refreshing to hear of someone with the same outlook. Bless you sir!

  5. Re:other states? on The Marshall Islands, Nuclear Testing, and the NPT · · Score: 1

    Simple enough - nuclear warheads wear out. They get stale, They cease to function. They must be replaced.

    The US had millions of rounds of 50 caliber machine gun ammo left after WWII - enough to last through all the wars since then. Is that stock still around? No - it was destroyed and replaced with fresh ammo. Same deal with nukes - they are not a solid block of stone, so they do no last forever. No complex weapon does.

  6. Re:Fluffy the feel good piece on The Next Generation of Medical Tools May Be Home-brewed · · Score: 1

    I got fed up with the 4 and 5 blade contraptions as well, and went back 'old school' with a safety razor, soap, and boars-hair brush. Didn't go full old school with the straight razor - that does take too much time to keep sharp, and some time to get skilled with it. The safety razor though is great - blades are maybe 4 cents a piece - I can buy 'em in hundred packs.

    Try it - you won't look back.

    The one advantage modern razors have though is that you have to really really try hard to cut yourself. The safety I have is not bad (and blades last around 2 weeks it seems), but takes a little care. Straight razor - forget about it.

  9. Re:They still have to add more risk to the equatio on Has the Supreme Court Made Patent Reform Legislation Unnecessary? · · Score: 1

    How about this for a potential solution? NIH, as federally funded, cannot or will not patent new devices you (and other researchers) come up with. Fine. How about sending copies of your writings directly to the Patent board - for inclusion in the body of prior art they use to reject patents.

    That may be one way to put them in the public domain, so to speak, so that companies could USE your design, but could not patent it for themselves - any patent application would just get rejected via prior art.

    May be worth a shot.

  10. Re:Make it DARKER dammit. on Spock and the Legacy of Star Trek · · Score: 1

    No, IIRC TOS had spikes of warp power far above warp 10 - can't remember the episode, and the ship was going to rip itself apart at any moment, but I distinctly remember speeds way above warp 10, at least for a few moments.

  12. Everything has a cost on Ask Slashdot: Terminally Ill - What Wisdom Should I Pass On To My Geek Daughter? · · Score: 1

    First off, bummer dude. Good luck with the time you have left.

    The only big lesson I ever instilled in my daughter, and I think it stuck, is that everything in life that you want has a cost. It may not be money - in lots of cases it isn't (my daughter's Field Hockey championships and ROTC scholarship for instance) - but there is a cost to everything. Figure out what the cost is, and if you want whatever it is enough to pay that cost - do that, and life is simple.

    The other I got from someone else - at some point EVERYONE becomes an orphan. When you can understand and accept that, you at least know you are not alone in your loss - sooner or later everyone has it.

    Good luck - god bless

  13. Re:You are free to have killer robots on Only Twice Have Nations Banned a Weapon Before It Was Used; They May Do It Again · · Score: 1

    From what little I've heard on the subject from U.S. Soldiers - they are generally OK with this

  14. Re:Useless on Canada's Next-Generation Military Smart Gun Unveiled · · Score: 1

    I'm neither, so take this with a boulder of salt.
    The difference between Soldiers and Marines is that the Soldier generally has a lot more support, and operated in larger numbers.

    When the Army goes in, there is generally close air support, artillery support, logistics support, MPs, lots of infrastructure, lots of hardware, Engineer support, etc..

    When Marines go in, they generally have a whole lot less, if any, of any of that (No implied slight to the Navy intended). Hence the credo "Every Marine is a rifleman" because it more often comes down to that when the stuff hits the fan (as compared to the Army). So each Marine has to be a lot more of a BAMF - sometimes that's all they have to work with.

    Does that help?

  17. Re:No. on Obama: Gov't Shouldn't Be Hampered By Encrypted Communications · · Score: 1

    Key exchange IS the problem - it relies on trust, partially, and obscure mathematics, partially. The keys are used for both parties, by using parts of the others' keys (i.e. the Public half of a Public/Private key pair) to generate the same Secret key. Then that Secret key is used to encode and decrypt messages.

    It is not fundamentally secure. The correct way to do it is to physically travel to the other party and exchange Secret keys directly - and use 4096 bit to boot. With keys that long it *is* mathematically unable to be cracked using brute-force methods. Ever.

    Well said sir, well said.

    I have only one daughter, and we raised her about how you were raised, and she has turned out very well indeed.

    I also have a sister-in-law that is unfortunately headed down the road of your sister, though maybe not for all the same reasons. It is very sad - we still try to get through to her, but the outlook is bleak.

    Stick to your guns with your children when you have them. We did, and it does work.

    One tip I can give though: The guiding principal I tried to instill is that everything has a cost - it may not be to you, it may not be money (success at sports takes other things than money - time, effort, patience, determination), but there is a cost to everything. Is what you want worth the cost? If so, by all means, go for it, pay the cost and achieve it. But you aren't getting anything for free - that's the real world.

  23. Re:5th Admendment? on 18th Century Law Dredged Up To Force Decryption of Devices · · Score: 1

    Unfortunately you are using the wrong test of a new law - you should never ask "is it being used responsibly here?", but ALWAYS ask "CAN it be used irresponsibly, anywhere?"

    If the answer to the second question is yes, it's a bad law. And must be opposed. Because sure as the sun will rise, someone will eventually do just that.

    The official procedures of Congress allowed for deadlocking the government permanently - basically sabotaging it from within. That was pointed out decades ago. "Oh, but we'd never do THAT" was always the response. Until a few years ago some members of Congress used it that way. With exactly those results.

    Don't look at the specific application being applied today - look to how it can be twisted in the future.
