  1. Re:My Dad uses it. on Hardy Heron Making Linux Ready for the Masses? · · Score: 1

    "retired rocket scientist " "he hasn't a clue how the machine works" ??? Give him more credit than that. I am sure he knows how the machine works, may be not at the detail you and I know.

  2. Re:Oooh, that is wrong... on Schoolboy Corrects NASA's Math On Killer Asteroid · · Score: 1

    Actually that 10km/s is closer to escape velocity in free space. In atmosphere, due to air resistance, that speed is improbable (it would be 36,000 km per hour; about 30 Mach) Based on http://en.wikipedia.org/wiki/Terminal_velocity analysis, if we assume a terminal velocity of 100 meters/s, Kinetic Energy = 0.5*10^11*10^2*10^2 = 10^15 Joules. (for a mass of 100 million tons) Now, if the asteroid disintegrates due to thermal and mechanical stresses, this calculation is kaput!

    And if all their predictions are based on this erroneous mass, isn't this a case of "Sky is Falling" nonsense?

    How does a 320 meter iron (and indium) ball end up with 200 Billion tons of mass? 1.33*3.14*160*160*160*8 tons = 136 Million tons

  5. Re:I see Windows Blue screen all the time on TV on The Death of Windows XP · · Score: 1

    Many small local cable TV producers use embedded Windows in their equipment. Sometimes, late at night or weekends, they crash and display BSOD on cable TV channels. Sometimes for hours.

  6. Re:XP? on The Death of Windows XP · · Score: 1

    Just reinstalled Win2K Pro yesterday to avoid WGA headaches. Need a Windows box to run Adobe SW. Once Win2K is EOL, it is Edubuntu (Ubuntu variant) all the way. Will have to master gimp, inkscape etc.,

  7. Re:now there is human / earth bacteria everywhere on Will Mars be a One-way Trip? · · Score: 1

    Do you realize, if that is true, that is a great achievement! We have created extra-terrestrial life for the first time in the know history of the Universe. It is an achievement as great as creating Artificial Life. Eventually, that bacteria may evolve into, who knows, ET or even little green men.

  8. Re:Bummer on LIGO Fails To Detect Gravity Waves · · Score: 1

    At least according to classical physics, energy = mass * linear velocity squared = mass * radius squared * angular velocity squared; Hence, when the stars lose energy, they can come closer (i.e. reduce radius) and keep angular velocity same (or even increase some); Another way of saying this is that they reduce their "moment of inertia (mass * radius squared)"; Or they can keep the same (or larger)radius and reduce angular velocity. Either way, it seems to violate conservation of angular momentum (if there is no other body to transfer momentum to); hence it can't be explained by classical physics using conservative fields.

  9. Fractional votes should solve the problem on Tweaking The Math Behind Political Representation · · Score: 1

    If we dispense with the notion that each vote should be one and start using fractions for voting, a lot of these rounding related issues should be easy to fix. California can have 54 representatives with a vote of 0.97 (say) and Idaho can have 5 reps. with a vote of 1.07 etc., so that population count of a State balances nicely with overall weight of representation. A lot of artificiality in our voting system is introduced by the rounding error of integer votes.

  10. hard deadline of 2010 for Shuttle retirement on More Solar Panel Problems For ISS · · Score: 0, Flamebait

    That also implies hard deadline for ISS usefulness. Even with the Shuttles, hardly any science was done beyond assembling the ISS. Without Shuttles, it would be very risky even to maintain an operating ISS, let alone do science. ISS was one big 100 Billion $ motel-in-space. Complete waste of money - if you ignore "lessons learnt" in fabricating large extra-terrestrial structures.

  11. On Win2K, Gigabyte size file copy corrupts NTFS on Vista Runs Out of Memory While Copying Files · · Score: 1

    Yes; I have verified on many machines and gave up on copying very large video files on Wiin2K. Always corrupted NTFS after more than ten 2GB or larger files were copied. Not sure if it happens on XP. Can anyone confirm if you can copy hundreds of multi GB files on XP?

  14. Re:Roll back 2 party system on Hacking the Presidential Election · · Score: 1

    I don't think substituting 2 party system by n party would make a lot of difference. This is what I see: In the last 40+ years America has failed to elect truly great leaders for President. I think the last great leader was Kennedy. After that we have had mostly mediocre Presidents. Yes that includes Nixon; Nixon was smart but he was a crook. That cancelled out and he ended up a failure. Clinton was smart but had his weaknesses that his opponents exploited. We don't have anyone running that is inspiring enough for me to vote. I will only vote because it is my duty.

  15. Re:Only about Half of the eligible voters vote. on Hacking the Presidential Election · · Score: 1

    I am paying attention and I am being realistic. I will try to prove my assertion by this simple "Induction" If the issues you stated were in play in this so called "Change" election, can you look me in the eye and say that all the front tier candidates are the best people to lead the country for the next 4 or 8 years? Is this what the "Greatest Democracy" of 300 million capable of producing? You want my answer? Better American minds have decided it is not worth the effort.

  16. Only about Half of the eligible voters vote. on Hacking the Presidential Election · · Score: 1

    Only about Half of the eligible voters vote. And even many who actually vote aren't particularly careful or sophisticated enough to understand the issues - remember Butterfly ballots & Chads? Sadly, my greatest cynicism is that the Presidential elections will get largely decided on Guns, Gays, God and Abortion. Not worth hacking.

  18. This kind of stuff has been happening before on MIT Student Arrested For Wearing 'Tech Art' Shirt At Airport · · Score: 1

    I remember an EE friend of mine of Iranian origin (U.S. Citizen) was always hassled when he carried a prototype circuit board (of cell phone processor)in a proper container while boarding aircraft (this with all paper work etc., in order). He had to resort to book it as cargo to avoid being denied boarding etc., This was before 9/11. When he was little, my son had shoes with LEDs that would light up when he walked. I think they would be major no no now a days. You want a real shocker? A friend of mine who was a Professor in Washington State had her Green Card cancelled and was told she was "Not Admissible into United States". (She had lived in US for over 10 years, had her family & home here). It took a lot of political intervention and a couple of years to get her Green Card back. Her crime? She had gone to East Berlin (out of curiosity) when she visited (west) Berlin for a conference. (This was during the days of Berlin Wall). Want another? Another friend of mine, a very respected computer system designer for military aircraft had to quit his job because they took away his SECRET clearance. What was his crime? He spoke too much (over phone) to his mother in a foreign country who was dying of cancer! He knew all his international calls would be listened to; but couldn't imagine anyone will find a problem with his phone calls to a obviously very sick old woman.

  19. He is about a year behind me... on PC Magazine Editor Throws in the Towel on Vista · · Score: 1

    I came to the same conclusions about a year back - except it was XP on my ThinkPad. Replaced XP with Linux, most of my pain went away. I am no MS hater. I have developed device drivers for Windows. Still own MS stock. But I am done with Windows as a home user.

  22. Pre-paid phones on Where In the US Can You Get Just a Cell Phone? · · Score: 1

    We use 2 Tracfones (both GSM, likely run on AT&T (formerly Cingular) network). Quite happy with service, fairly inexpensive for occasional use. Both the phones (supplied for free by Tracfone) are made by Motorola. I also use a Cingular pay-as-you go service, Quite happy with service, fairly inexpensive for occasional use. If I have to use lot more minutes, I may switch from Tracfone to T-Mobile. The phones are cheap enough for me that I don't mind giving it away to guests/visitors, don't fuss if I or family member lose it, generally treat it as a somewhat expensive pen or a wristwatch. In short, it is not valuable.

  25. If one wants to clone, Why not pick MacOS instead? on ReactOS Code Audit · · Score: 1

    If ReactOS folks want to sweatout an open source OS, why not pick a better product to clone? An open source MacOS on X86 can work wonders. Especially, now that the real MacOS runs on X86. MacOS is based on FreeBSD, it will have much less legal headache to worry about. (I haven't heard of any leaked MacOS source, has anyone?)
