  1. Re:Calculator key? on Blank Keyboard · · Score: 1

    I would actually pay a chunk of money to have an old Sun3 keyboard that worked with pc hardware. Definately the nicest keyboard I've ever used.
    Ditto with mice. Where did three button mice go?
    Come to think of it, what I need is an old Sun3 with new guts...

  2. Re:What Science Really is... on Kansas Challenges Definition of Science · · Score: 1

    That is the funniest thing I have ever read on slashdot. Thank you.

  3. Re:What if Dark Energy Wasn't Required on Fermilab Reports Dark Energy Not Needed · · Score: 1
    Maybe the whole FRW cosmological model is wrong. It assumes the universe is homogeoeous. Here, someone argues that this assumption may be wrong:

    (at http://arxiv.org/abs/astro-ph/0503715 sorry, the preview button makes me think the URL: isn't working)

    Abstract: It is widely believed that the assumption of homogeneity is a good zero{\it th} order approximation for the expansion of our Universe. We analyze the correction due to subhorizon inhomogeneous gravitational fields. While at early times this contribution (which may act as a negative pressure component) is perturbatively subdominant, we show that the perturbative series is likely to diverge at redshift of order 1, due to the growth of perturbations. So, the homogeneous Friedmann equation can not be trusted at late times. We suggest that the puzzling observations of a present acceleration of the Universe, may just be due to the unjustified use of the Friedmann equation and not to the presence of a Dark Energy component. This would completely solve the coincidence problem.

  4. Re:twm rules!! on Blackbox (Finally) Updated · · Score: 1

    I agree! I've been using twm for fifteen years, and it does everything I need [1]. And I just checked; the binary is 190164 bytes. WHat do all these new WMs have that twm doesn't?

    [1] Well, I would like a "minimize all windows" function, but it's a minor nit.

  5. Re:More info.. on Hawking Gracefully, Formally Loses Black Hole Bet · · Score: 1

    I just found this transcript of the talk: http://pancake.uchicago.edu/~carroll/hawkingdublin .txt This was found in a thread on sci.physics.research, BTW.

  6. Re:geteralization and compression are equivalent on Mesh Compression for 3D Graphics · · Score: 1

    Work in machine learning has proven that generalization and compression are equivalent. I'd like to hear more about this. Can you provide a pointer or some references, please? Thanks.

  7. Re:Cook more "claimed" Australia than discovered. on Venus Transit Finished · · Score: 1

    What was the name of the book that you read? Or, any other recommendations for such a history?
