  1. Its a good choice on The Best Near-Term Future of Space Exploration? · · Score: 1

    Apollo had enough delta-V for a mission to a near earth asteroid, and could have made the duration with a stretched service module for more life support. The design issue is whether to build a big, slow vehicle, or a small, fast vehicle. The slow option gives you more to build on for the future. The fast option has less risk because a quick return to Earth is built in from the start.

  2. Re:alternatives for shallow gravity wells on The Best Near-Term Future of Space Exploration? · · Score: 1

    Except that Phobos and Deimos are both well down in the gravity well of Mars. Asteroids orbiting the sun are much easier to get to, especially those with orbits which cross the orbit of Earth.

  3. Re:Honest question on Shakespeare In Klingon? · · Score: 1

    Yeah Klingon is worse than Ada in that regard, but easier to debug I reckon.

  4. Re:Great news on It's Official — AMD Will Retire the ATI Brand · · Score: 0, Redundant

    Looks like a photon travels 10 cm in a clock pulse at 3GHz.

  5. Re:It seems that you could detect this on Hackers Eavesdrop On Quantum Crypto With Lasers · · Score: 1

    So Bob could just detect the blinding signal and stop transmitting.

    Alice is the transmitter, Bob is the receiver (from A to B, see?).

    Yes I can see my mistake, though once Bob knows the link is compromised he can ignore the contents, so the hacker can't predict his behaviour. Also Bob could use a different channel to notify Alice of the problem.

  6. It seems that you could detect this on Hackers Eavesdrop On Quantum Crypto With Lasers · · Score: 2, Interesting

    Eve gets round this constraint by 'blinding' Bob's detector — shining a continuous, 1-milliwatt laser at it.

    So Bob could just detect the blinding signal and stop transmitting.

  7. Re:Why really does Apple behave this way? on iPhone App In App Store Limbo Open Sourced · · Score: 1

    How about failing to pay homage to SJ?

    But authoring uses a simple language called bs. BS is a simple language written specifically for creating briefs.

    Reading the web site it does look like a new development tool. If apple want to force people to use their tools (because the tool enforces policy) then it seems logical they would want to tie this one up in the approval process.

  8. Scratch on What 'IT' Stuff Should We Teach Ninth-Graders? · · Score: 1

    Recently somebody pointed me to Scratch. Its a simple, fun, programming tool. It is aimed at kids eight years and above but I am sure it would be appropriate for some 14 year olds too. My dad is teaching computer skills at U3A. He is interested in using this tool in his classes.

  9. Re:The Future Today in 30s - makes perfect sense on Jet Packs, Finally On Sale · · Score: 2, Insightful

    What they did not foresee in 1980 was the rise of telecommuting and that those same commuters would not have to travel very far.

    More to the point, even though it is 2010 the laws of physics still apply, and there haven't been significant breakthroughs in compact power plants for jet packs.

  10. Re:ok but on Machining a TI-89 Out of Aluminum · · Score: 1

    I heard this in the 1970s about a guy who had a timber seat on his hang glider. He crashed the glider and broke the seat. Rather than replace it he reinforced the seat with a strip of steel so it wouldn't break in future hard landings...

    Yeah or sell a service to map commercial developments.

  12. Re:True patriots on Just Where Is The Lincoln Memorial, Anyhow? · · Score: 1

    How does that 6% compare to other countries? I'm guessing it's not that different from many others, and probably a lot higher than many countries with lower education.

    Voting here in Australia is compulsory and I live next to a school (polling place) so every election day I get a close look at that lower 6%.

    A couple of years ago there was this guy who got his car stuck on a curb at the back of my house. There is a change of level and one driving wheel was partly off the ground. The resulting problem in 3D geometry was totally beyond him.

    Traffic outside polling places can get a bit heavy and last Saturday this guy left his car in the middle of the road and ran after some bloke and threatened to cut his head off or whatever. He had obviously been trolled and proceeded to try his best to get arrested within the bounds of a polling place.

    The phrase "shit for brains" comes to mind for a proportion of our population. I wish they could just stay home.

  13. Re:So in essence... on Pentagon Selects Companies To Build Flying Humvees · · Score: 2, Insightful

    Before I read the article I was thinking in terms of an advanced ground effect vehicle. Maybe with four small turbine engines. Enough to get you over a road block, and set fire to it as a bonus.

    Another thought was the hybrid APC in Aliens. The top half is basically a helicopter. It drops on to the road and releases an armoured vehicle. The helicopter alone is very light so it can loiter above the field of operations providing a high view of the area. When the APC wants to be picked up they find an open area and the two components join up, probably in a few seconds.

    I cannot express how grateful I am at knowing that no child of mine will ever have to fly in one of these abominations!

    Yeah my workplace is a power point tragic. One time the annual christmas dinner had power point. I noticed recently that power point is now an acceptable format for resumes at many employment agencies.

    This is where I get off...

  17. Re:Location on UVB-76 Broadcasts New Voice Message · · Score: 1

    Yeah I think light diffracts around the object creating the shade so if the object is thin, you hardly see the shadow. A sextant would help though and you could probably hack one up out of timber. Otherwise you could always use a barometer

  18. Re:I wonder why did it take so long on Glibc Is Finally Free Software · · Score: 3, Informative

    The article goes into some detail. To change a license you need the agreement of the authors. Over time the authors become hard to track down.

  19. Re:Why use a sub-standard Desktop? on Making Ubuntu Look Like Windows 7 · · Score: 1

    I think apple have invalidated this whole argument with the iphone, and google are doing same with android. As long as people can see how to find their stuff they are okay. They don't need a windows symbol to remind them that all is well.

  20. Re:Why use a sub-standard Desktop? on Making Ubuntu Look Like Windows 7 · · Score: 1

    And since you raised the issue of fvwm, this idea of making things look like windows was interesting in 1995 but now it just seems redundant.

  21. Re:In other news.. on Google Testing Instant Search Feature · · Score: 1

    Yeah. My wife and I are in different countries right now and we have been making use of google latitude and calendars to keep us coordinated with the stuff we both need to get done. Google tools are useful but buggy. They give the impression that development stopped when they became useful and that nobody sees the need for improvement.

  22. Re:Designing such a site is easy... on Digg In the Future · · Score: 1

    Yeah their comment system looks usable. The comment system on digg OTH looks like they decided to have a comment system but set out to make it as ugly and useless as they possibly could, and more than likely put a lot of effort into it too.

    No Julian I think its perfectly normal.

    To keep watching the same program you must remain absolutely still in front of the TV.

    But seriously, the gesture to shut something down would require exactly one finger...

  25. Re:How about on Look-Alike Tubes Lead To Hospital Deaths · · Score: 1

    How many nurses did they have in the maternity ward/wing? How many mothers in recovery, how many newborns in postnatal care, how many actual births happening at that moment? Did they have an unplanned delivery happening at that time?

    This was a private hospital with a good nurse/patient ratio. In a public hospital she would have had to share a room and would have been better off because there would be more people around to call for help or directly help her. A private room is nice but potentially more dangerous.
