  1. penrose lecture online here on Roger Penrose and the Road to Reality · · Score: 1

    Here is a really fun lecture given by penrose in 1999 (slides+audio). In it he talks about some of his pet theories of consciousness, but also a really cool example of transcendental induction.

  2. Re:An Interesting Index on Roger Penrose and the Road to Reality · · Score: 1

    Smolin is still to young and crazy to take the time to write something as comprehensive as TRTR; Penrose took 10 years to write this book!

  3. Re:I think this is good on Roger Penrose and the Road to Reality · · Score: 1

    I just hope this book doesn't do anything like imply that there's any evidence whatsoever for the veracity of string theory.

    Penrose hates string theory, and in this book he sure let's everyone know that.

  4. quoted out of context on Lack of Testing Threatening the Stability of Linux · · Score: 2, Informative

    I was there, and the quote was taken _absolutely_ out of context: 'If you pick a good technology and the developers are insane, it's all going to come to tears.' He was not refering to BK in this instance; he was in fact talking more generally about SCM systems, and how he had noticed that these projects tended to attract "insane" developers (also the ide drivers do this too).
    This was all part of a larger, very insightful remark, saying that had Linus chosen a free SCM tool three years ago, we would now have a fantastic SCM in the free software world. In this instance, it is not so much the _tool_ that would need to be good, but that the _team_ behind the tool needs to be solid, responsive etc.

  6. Re:Carpal Tunnel? on Programming Until Retirement? · · Score: 1

    This ergonomic mouse from 3m is totally brilliant. It's the rotation in the forearm when using a mouse that causes most of the problems.

    Here is a picture of my homegrown ($15) solution. (Note also the juggling ball I use as a wrist rest).

  7. Machine Learning paper and "Kill Bill" on Coming soon: Google TV? · · Score: 1

    I was just reading this paper. Towards the end of the paper they apply their kernel methods to clustering video clips from the movie "Kill Bill". The technique directly works with the video data.

    I've seen some of the short films that AFTRS students produce, and they are world class productions. Really brilliant.

  9. motion sensors for music on DIY Warriors Saluted And Sought · · Score: 1

    I am part of a trio that uses motion sensors to perform sound art:
    Hypersense Complex
    These are custom built microcontroller / USB devices.

    We are currently exploring the use of accelerometers, with a view towards full motion capture. However, this is a difficult problem to solve, as gravity provides a constant acceleration offset. Another area we will be looking at is useing wireless chips, eg. the honeywell ROC chips.

  10. Lode Runner on Retro Gaming Gets Hot · · Score: 2

    I think the last game I really enjoyed playing was Lode Runner. And that was 20 years ago, on my friend's AppleIIe. Games these days mostly leave me cold. And I'm not interested in brilliant "realistic" graphics, what's the point ? What get's me going is when my mind is engaged: I want abstract games, games that put interest/novelty/gameplay first.

    For some time now I've been working on a 3D version of lode runner. Here are some screenshots. There are some other differences to the original, such as being able to walk on the walls and ceiling. This creates some interesting topology! I even sampled the original sounds from an AppleIIe I bought recently. It's a kicker.

  11. Reading the masters on Great Computer Science Papers? · · Score: 1

    I've found these two papers to be not only easy and fun to read but perhaps the best introduction to the feilds of study they inspired.

    The first is Knuth and Bendix, "Simple word problems in universal algebra" from 1970. This was the foundation for term rewriting.

    The second paper I would recommend is, Dana Scott, "The lattice of flow diagrams", from 1971, which is a very sweet introduction to some serious mathematics of computation (domain theory).

    What continues to amaze me is the simplicity of the ideas presented, and how you get a great sense of the author's original excitement about the subject, which is often not present in more "modern" and abstract treatments.

  12. Anyone interested in hacking this? on Cheap Wireless for Accessories · · Score: 1

    This looks really fantastic for some microcontroller based music instruments that i work with: hypersense.
    Right now we are tethered by USB lines, it's not such a big problem, we stand still mostly during performance. But for some more dance oriented work we will need wireless, definately.
    I'd be interested in exchanging notes with anyone who is thinking of trying these chips out.

  13. Impressions on Linux Conference Australia Write-Up · · Score: 1

    So I cooked up this logo for my local linux users group, and they nominated me for Sun's regional delegate program. Wow! Being flown across Australia to attend LCA2003, what a blast.

    ...Saying hi to 5 people before my first coffee of the day;
    ...the kernel, is it too big? Can these guys pull it off?
    ...Where are the gcc people? Is this the GNU/Linux divide? It seems the kernel is in bed with GCC.
    ...Okay, some things are simpler in 2.5, phew!
    ...Another nametag, another famous person, another nerd, another one i've seen on my favourite mail list.

  14. Praise for Andrew on Australian Open Source Awards · · Score: 1

    Andrew is not just a coder, he is truly inspiring.
    I have sat with him going over some of his code-
    syntax colouring, that lego feeling, elegance.
    He was the one who really taught me about programming in c;
    how effortless it can be.

    A simple idea: ccache
    A deeper idea: genstruct

    May he win many more awards!

  15. Re: he does this in mathematics too on Knuth Releases Another Part of Volume 4 · · Score: 1

    The Don likes "lowlevel" notation.
    Have a look at some of his math papers;
    they use , ummm, let's say, the nuts and bolts
    of math (set theory). This is his style.

  16. Re:SDL game contest downloads on Slashback: Games, Goats, Galileo · · Score: 1

    Thanks to John and all the other Judges!

    I had a lot of fun working on Axis Runner,
    a game i have been working on and off for some years now.
    It is inspired by the apple II game "Lode Runner".
    I added another dimension and changed the topology of things a bit :),
    but you still run around diging holes, and collecting parcels.

    It's not released yet anywhere, and you may need to be a genius to play it,
    but you can download the latest source from my page here.
    I still work on it, currently i am working on the audio engine.

  17. this article is crap on The Story Of GMR Heads · · Score: 1

    Obviously the writer has no understanding of the subject matter.
    It is written so that it seems like it may be informative, but for anyone with a brain it is clear that it is a mish-mash of facts that when put together make little sense.
    This is the worst kind of obfuscation, but calling it obfuscation implies the writer knows what he/she is talking about, and this I doubt.
    Thankfully, the slashdot crowd can make up for this sorry lakuna of an article, with several coherent (not this one!) comments, that actually make me think.
    Now, how do we tap into this wealth of knowledge and experience without having to read crap economist no-brain articles like this?

  18. Re:ion is great, see also PLWM on The Waning of the Overlapping Window Paradigm? · · Score: 1

    I'm backing this reader here.
    never used ion, but my windows
    are always tiled.
    I am definately interested in
    extending this paradigm down
    into the apps themselves.
    Yes, X is scary in the begining :)
    but, i have been playing with a
    funky python X library.
    on top of which is built PLWM,
    the pointless window manager,
    like PWM and ion, i guess.
    Somehow python makes X a lot less
    formidable.
    Well i'd like to see how possible it
    is to build a toolkit on python-xlib...

  20. python WM and shells on Has the Development of Window Managers Slowed? · · Score: 1

    i have become interested in plwm, which is
    a WM written in python!
    there is some truly magical code in plwm
    in particular the python-xlib core.
    Anyway im interested, cause i love python,
    and i believe in power to the user.
    This question also relates to shell programing;
    in the beginning it was expected that people
    would write their own shells...
    well, how 'bout it?
