  1. Re:Well, in fairness... on Comet Nearly Hit Earth? Not So Fast · · Score: 1

    I'm sorry to say that you're wrong on most accounts.

    Astrophotography did exist and Bonilla took a photograph of the phenomenon.
    No, the telescope was not aimed by hand.
    And no he wasn't the only guy observing the sun at that time.

    Source: http://gallica.bnf.fr/ark:/12148/bpt6k2096403/f351

  2. For the record on Comet Nearly Hit Earth? Not So Fast · · Score: 1

    The 2011 paper can be read here: http://arxiv.org/ftp/arxiv/papers/1110/1110.2798.pdf
    Bonilla's 1885 paper can be read here: http://gallica.bnf.fr/ark:/12148/bpt6k2096403/f351

  3. The original paper on Comet May Have Missed Earth By a Few hundred Kilometers · · Score: 1

    The original paper, published in 1885 in L'Astronomie can be read online here: http://gallica.bnf.fr/ark:/12148/bpt6k2096403

  4. The Bird Theory on Comet May Have Missed Earth By a Few hundred Kilometers · · Score: 1

    For those interested, here is a drawing of a swarm of cranes, observed on the solar disk with "slow motion": http://gallica.bnf.fr/ark:/12148/bpt6k209642v/f72 (this is from the same journal, L'Astronomie, which is on line on the Gallica web site) It is reported that people suspected the earth atmosphere to be responsable for many sights of objects seen across the solar disk. In this paper, the author believed at first he was observing metors. From the size of the birds (assumed to be 1 meter), he calculated they were flying at a height of 9 km.

  5. Re:Error in measuring distance perhaps ? on CERN Experiment Indicates Faster-Than-Light Neutrinos · · Score: 5, Informative

    They claim they are confident about the distance to within 20 cm.

  6. Re:What speed? on CERN Experiment Indicates Faster-Than-Light Neutrinos · · Score: 1

    It is claimed that the paper is on arxiv but I can't find it.

  7. Keepass' answer to brute force attacks on Cheap GPUs Rendering Strong Passwords Useless · · Score: 1
    Paroting the KeePass website:

    'You can't really prevent these [brute force] attacks: nothing prevents an attacker to just try all possible keys and look if the database decrypts. But what we can do (and KeePass does) is to make it harder: by adding a constant work factor to the key initialization, we can make them as hard as we want."

    To protect its database (of passwords), the program actually performs N rounds of AES encryption, with N being a large number of your choice, chosen so that these rounds take "a lot of time", say 1 second. This way, the attacker will only test 1 password per second.

    Does this make sense ?

  8. Re:Would GPS have helped ? on Flight 447 'Black Box' Decoded · · Score: 1

    The last time I checked, the error on GPS altitude was significantly larger than the horizontal error. However here you're writing about vertical speed, which could be more accurate than the altitude. Since it is not used for measuring the descent rate, my guess is that is is not reliable enough when other instruments are available.

  9. Re:Would GPS have helped ? on Flight 447 'Black Box' Decoded · · Score: 1

    Not at all. What matters is airspeed. GPS just doesn't provide it.

  10. Another one on MoD's Error Leaks Secrets of UK Nuclear Submarine · · Score: 1

    Another occurence of this type of error happened before in the Calipari Report

  11. Re:Not new on Couple Sends Record Player Wedding Invitations · · Score: 2

    I remember seing a german paper record player like this one in the eighties. It was voice only and I was amazed. The sound on this one isn't that great. There is an other design with a paper-cone.

  12. Re:one thing most people miss on Glasses-Free 3D On iPad (Sorta) · · Score: 1

    Agreed. It would work as is if the camera was detached from the display and the display rotated to always be in the normal direction.

  13. Re:Umm yeah... on Spacecraft Sends First Image From Mercury's Orbit · · Score: 1

    He's not on Mercury: you can find him on asteroid B612

  14. Low 3D ? on Does 3D Make Your Head Happy Or Ache? · · Score: 1

    The "3D" effect isn't binary: it can be adjusted. It would be interesting to study how headaches change when the 3D effect is increased from zero to max by increments. Maybe a small 3D effect can be immersive without the headaches.

  15. I prefer cockroaches on Researchers Test Drive Bus With Automated Steering · · Score: 1

    Personally, I'd leave it to a coackroach (http://science.slashdot.org/article.pl?sid=05/07/03/0426258) to park my car/bus/van.

  16. Email who ?? on Best Buy + Windows Guru = Apple Store Experience? · · Score: 1

    On the Application for Windows Guru page, I read "If you have any difficulties with this form, please email Jobs@mswindowsguru.com" I didn't know that Steve worked for Microsoft. Hilarious!

    Moderate parent up, please. This is not news for nerds. And it doesn't matter the least.

  19. Re:The press release on Japanese Probe Returns First HD Video of the Moon · · Score: 1

    The satellite was confirmed to be in good health through telemetry data received at the Usuda station. Hmmm. The moon's doing fine ? Yes, I already know that.

  23. Also consider webcams on Entry-Level Astronomy? · · Score: 1

    I agree with the binocular advice.
    Since you do not say if you are interested by planetary astrophotography vs. deep sky, let met add that a Webcam turns out to be a perfect device for planetary astrophotography.
    Let me quote the following website (http://sctscopes.net/Photo_Basics/Webcams_for_Planets/webcams_for_planets.html)
    "It takes a whole bunch of frames (i.e. photos) in a row, and all that's needed is software to accumulate the photos, decide which ones are good, and stack them together to create a good planetary photograph. During the recent historical Mars opposition, many astrophotographers created amazing photographs of Mars using Webcams."

  24. Another simple question on Help Find Steve Fossett · · Score: 1

    Anyone knows how to turn off the "before" layer ? Viewing both layers at once makes the picture very dark and features are hard to figure out. Thanks.
