  1. Re:collision on Hubble Takes Pictures of Colliding Galaxies · · Score: 3, Informative

    I don't know about your story, but I do know that the focal length of the hubble miror was wrong, and they only detected it when it was actually in space, due to damage (lost chip of paint IIRC) to a mesuremant device.

    Well, I don't understand the rules or point of baseball, for that matter.

  3. Re:Holy --deleted-- on Radioactive Snails Crawl Up From Beneath · · Score: 5, Informative

    Sigh. From the article:
    three U.S. hydrogen bombs fell by accident 40 years ago may trigger a new joint U.S.-Spanish clean-up operation, officials said on Wednesday.

    The hydrogen bombs fell near the fishing village of Palomares in 1966 after a mid-air collision between a bomber and a refuelling craft, in which seven of 11 crewmen died.

  4. Re:Why Bother? on Fingerprinting Wireless Drivers · · Score: 1

    Um, what? 802.11n has takes that up to 50 metres, and we all know that a good directional antena can pick up signals from a great distance. And there is no reason to think that somone attempting to crack a system will use legal wattages to do it! I hope I am not feeding a troll here....

  5. Re:License? on Google Releases Tesseract as Open Source · · Score: 1

    Probably because noone selected a licence from the drop-down box on the submission form. And _that_ was probably because parts of the code are under at least 2 licences, one of which is non-free.

  6. Re:What about "rough ocr" on Google Releases Tesseract as Open Source · · Score: 1

    Just to remind you, 50% means every second letter is wrong. As in, you've got a 6.25% chance that a four-letter word would be correct. (Bit like my typing skills). I think you need something a bit better than that....

  7. Re:What will happen if the sheep believe this... on Net Neutrality Is Just "Mumbo Jumbo" · · Score: 1

    Will it work when the net partiality ISPs are charging $0 for their offerings (or even paying you!), and the net neutralities must charge a few hundred to break even?

  8. Whats wrong with the colour? on The Light Bulb That Can Change the World · · Score: 2, Interesting

    I find it intersting that many people are complaining about the colour temperature of CFLs. I don't know if it is the case in other countries, but here in Australia, we have the choice of at least three, sold as 'warm white', 'white' and 'daylight'. Personally, I much prefer the slightly blue tone of daylight, find white acceptable, and 'warm white' is more a horrid, dull orange.
    Can you get a range of colour temperatures in other countries?

  9. Re:Neptune and Pluto on Pluto Decision Meets with Frustration · · Score: 1

    True: I didn't think of that at the time. Yes, they could have done better with the definition: Although maybe it will be further fleshed out, and the definitions of the terms used clarified (what do they mean by 'cleared?, for example.) Still, no definiton of a planet that maintains sanity will include the first of the kupiter belt objects to be discovered (ie, Pluto)

  10. Re:Accept pluto, accept: what? on Pluto Decision Meets with Frustration · · Score: 1

    (OP Here)
    So, option 4: abandon the word. That was actually my preference, but I think it is less than ideal: somewhat of a easy-way-out.
    But their decision has had a great effect: It's got peopole talking and thinking about astronomy. Even if they think the IAU is wrong, at least they think: that's got to be a good thing.

  11. Wrong on Pluto Decision Meets with Frustration · · Score: 1

    Mercury is twice the size and 4 times the mass of Pluto.
    Mercury has a circular orbit, on the planetery plane, and has cleared its orbit.
    There is only one body like Mercury, whereas there are many like pluto.

  12. Neptune and Pluto on Pluto Decision Meets with Frustration · · Score: 3, Informative

    As an interesting extension, it could be argued that Neptune has also 'cleared' its orbit. Pluto is locked into a 3:2 orbit with Neptune, and this is fixed by Neptune's gravity. Neptune has forced Pluto into a stable orbit WRT itself, and so has cleared its orbit.
    Correct decision, IAU, well done

  13. Accept pluto, accept: what? on Pluto Decision Meets with Frustration · · Score: 1

    It's not just Xena, Charon and the asteroid Ceres: there are hudreds of pluto-like objects out there. If we created a definition that included pluto, then we would have to accept those hundreds of others.

    I don't know if that is a reasonable option

    So, what should they have done?

    • Left it undefined, and stated that there are nine planets, MVEMJSNP, despite what we know about the solar system. This option is ridiculous, but it seems to be what many are suggesting.
    • Create a definition which removes pluto, but include it for sentimental reasons. I don't think this idea is any better
    • Make a definition that includes pluto, and untold hundreds of other objects. That is chaos.
    • Abandon the word 'planet', and let the media use it to describe anything they wish. Then create their own, new nomenclature system that accurately describes the universe as we know it. This is sane, but maybe not elegant.
    • Define 'planet' according to our current knowledge, correcting the mistaken labelling of pluto in the process. This really is the only good option, and is the one they have taken.
  14. My Very Easy Memory Jingle on Pluto Decision Meets with Frustration · · Score: 1

    An old lady on the radio last night reminded us of {on of} the standard memory aids:

  15. Preferably, let's abandon the word planet. on Geologists Angry About New 'Pluton' Definition · · Score: 1

    I think that the word 'planet' has been thoroughly missused, to the point that it no longer has a scientific meaning. Astronomers should recognise this, make their own, new, descriptive system of nomenclature, and leave the word 'planet' to our imaginations, newspapers and their universities media offices.

    A nice suggestion was made by another poster: Extending the greek/latin roots of the words asteroid etc.

  16. Re:Priority Management on Biofuel Production to Cause Water Shortages? · · Score: 1

    I recently saw a documentary that was promoting solar power. They stated, proudly, that harnessing 50km square, they could power Australia. They illustrated that by painting a 50km square yellow on a google maps picture of Australia. Looked small. Looked easy.

    Until you do the maths and realise that they are talking about 2500 km^2 (50kmx50km). And they did not mention 'efficency' anywhere - can 50% be achieved? Does that make it >5000km^2?. When expressed like that, you realize that solar power will never solve anyone's energy needs, outside of low-quantity, remote power schemes.

  17. Re:hitting it on Computer Voodoo? · · Score: 1

    A real art major (or knower of basic science, for that matter) would know that magenta is the color you get if you mix red and blue in an additive system, as happens when the green circuits fail on a CRT.

  18. The nature of your dots counts on Hardware for Homebrew Motion Capture? · · Score: 1

    One suggestion: Do this in a poorly lit area, and have lights mounted on your cameras. (Ideally, they would be almost the only light sources.) Use reflective tape for the dots.
    You will then have very bright spots on an almost black background. That will make recognising the spots easy, even for the most brain-dead of algorythms.

    Professional 'body mechanics' use reflective spheres.

  19. I'm quite sure that this is actually done already. on OLGA Shut Down by DMCA (again!) · · Score: 1

    Many published lyrics and chord sheets (I'm a keyboard noodler, so I don't try the tabs) seem to contain obvious errors. Things that anyone with an ear will know are wrong, not just mishearings. I've usually considered these to be inserted for legal reasons.

  20. Whistling is illegal! on OLGA Shut Down by DMCA (again!) · · Score: 1

    No, you cannot whistle your favourite song on the street. That is a public performance, and is a violation of copyright.
    Remember, stores selling instruments have to pay royalites, in case a customers noodling happens to resemble a copyrighted work. Oh what a borken web we weave.

  21. Why is it in RIAA's interest to destroy music? on OLGA Shut Down by DMCA (again!) · · Score: 3, Interesting

    People become musicians by playing with music. First step is often chord based from sites like OLGA. Then progressing to full tablatures, again from OLGA. Then they are good enought to start making money.
    Then they start paying royalties on songs they cover when they start selling music, or mildly serious public performance. RIAA starts making money. But it all starts from those guitar tabs!
    RIAA makes money from talent. Talent starts from OLGA. So RIAA makes their money thanks to OLGA. What a great reasong for RIAA to shut it down.
    If I thought that they had any logic, I'd be puzzled. But this is just so typical.

  22. My WGA Issue on A Different Kind of WGA 'Problem' · · Score: 2, Interesting

    Here is my WGA story.

    A client's laptop started complaining. I checked its key, and it did not match the key on the sticker. So I attempted to change the key. No go with MS's vba script. No go with the activation wizard (which is another suggested way to change it) - it stated that the key was invalid. Further 'hacking' with the activation wizard (No, I don't know what I did, but there was a maximum of three buttons I could have clicked, and one of them was 'cancel!') got me a key I could use on the phone, and, after telling a bored Indian the story ("Have you installed this software on any other machine?" - I swear that quoting a snatch of Alice in Wonderland would have succeded!) he coughed up the activation code. WGA no more, but my it's a drag!

    If I charged them full price, It may well have been more than a new licence. Even so, it probably would have taken just as long to get it to accept the freshly bought key.

  24. Re:Global Warming? on Vermont Launches 'Cow Power' System · · Score: 1

    Actually, it has a large anti-greenhouse effect, well, for something done by one person on one farm, anyway.
    Remember that methane is a very effective greenhouse gas. Collecting and burning it exchanges it for much more friendly CO2, as well as replacing coal produced energy.
    There is a town in europe (Germany, maybe?) that is running its bus and train fleet on methane.
