  1. No, it is probably right on Philips Develops Fluid Lenses · · Score: 3, Informative

    Depends on the properties of the liquids. On the left, the blue liquid is convex and the brown concanve, and on the right the blue is concave and the brow convex.
    So, if light is faster in the blue liquid than in the brown one, the light-rays would move as described.

  2. Re:depends on the definition of lost on Recoverable File Archiving with Free Software? · · Score: 1

    You are right, it seems that iso9660 can not handle more than a depth of 7 (not including the root). I never encountered it till now - my home dir must not be very deep - I encountered problems with long file names instead.
    It seems that the rock-ridge extension deals with this by putting deeper directories into a dir called RR_MOVED, so I think if you use mkisofs with rock ridge all is fine (which could be another reason that I didn't encounter the depth limit)

  3. Re:depends on the definition of lost on Recoverable File Archiving with Free Software? · · Score: 1

    That is actually exactly what I do - full, uncompressed backup - takes 5-6 CDs in my case. Then I do incremental backups of the changed files till that goes over 1 CD (level 1 & 2). Redundancy comes from having each file on several backups...
    But rar would be better if it was more widely distributed and free (speech) - then i'd save a copy of the decompressor and its source code on every CD...

  4. depends on the definition of lost on Recoverable File Archiving with Free Software? · · Score: 1

    I've had a backup of my hard-drive on another drive, in tar.gz form.
    Ofcourse, when the big day came, and my hard drive broke, it turned out the other drive had bad sectors!
    First, a comment: never ever ever ever use tar.gz to back up anything you'd like to have back.
    You can recover stuff easily from tar past the break point - files in tar are basically concatenated together. So you miss the rest of the current file, but you can find the next header+file easily.
    But gzip does not byte-align its data! That's, in my oppinion amazingly stupid. It saves a couple of bits per file, but makes recovering a real hassle.
    I had to go through the file past a bad point bit by bit (literaly) to figure out if that is that next data block.

  5. Just depends on the odds on Defending Earth From Asteroids With MADMEN · · Score: 1

    Since a sizeable astroid hits maybe once in a million years, you have a lot to play with.
    Once in how many years a mad dictator/president could try to extort the rest of the earth? (remember that we had a fair share of mad dictators/presidents in the last 2000 years)
    Once in how many years a group of madman might try to return earth to "it original state"?
    Once in how many years someone might want to commit a really spectacular suicide?

  6. Sagan on Defending Earth From Asteroids With MADMEN · · Score: 5, Insightful

    I think that Carl Sagan made a very good point, saying that the chance of an astroid hitting earth is increased when one develops a technology to deflect astroids from their path, not decreased.

  7. Great! Invest more! on US Military Builds MMO Earth Simulator · · Score: 1
    This is really great. How about they invest $300B, build a really super-duper high resolution 3D virtual reality 2nd earth, and move there ?

    I'd be willing to pay a large percentage of my income for its upkeep. Inside there'd be no need to keep up with the Kyoto protocol, and we can set up global warming to whatever they want! Or, we could even set up an extra flat-earth version for those that are really hard to convice.

  8. this isn't exactly correct.... on AMD Back in the Black · · Score: 1, Insightful

    The right statement would be that in order to make a profit, the percentage of duds have to be equal or less to those that your competition makes.
    A rate of 10% failure can not raise the price of the chips by more than 10%.

    I know this will be lost in Score:1 limbo....

    That would be a cool project: software+hardware to link two telescopes that are 1000km apart, so that you get a 3d view of the moon. But - maybe
    that is too much an effort just to see the moon 3d.

  13. How badly does intel want chip ID? on Intel Putting Wi-Fi into Future Chipsets · · Score: 1

    It seems chip ID didn't work te first time. People were too paranoid. Others were saing that you have an ID anyway, because you have one on the ethernet card.

    Hey! So why don't we just put the card on the chip? No one can argue with that!

    But it could also be that they just want a monopoly over wireless... but why? why not put the sound on the chip? Or the graphics chip? Is it really that much more energy efficient to have the wireless card on chip, but it doesn't help much for graphics? Anyone?

  15. globals on 'Storage' to Replace Traditional Filesystems? · · Score: 1

    I don't agree.

    It seems to me that this has the same benefit as having globals in programs.
    I mean - globals are great: instead of passing a zillion of parameters to every subroutine, you just have a global called 'soup', and then if you change soup from 'chicken' to 'noodle' all subroutines that deal with the soup will immediatly know that the type changed.

    The problem is that it all works nicely when everything works well. But if you try to debug a program, to see how soup got to be 'nou%^%$&*", things are much less nice.

    Same with a global data structure instead of files. Imagine you'd have to figure out which program keeps moving your appointments to monday everytime the 29th of april arives.

  16. back and forth is quite primitive... on Netscape Founder Says Web Browsing Innovation Dead · · Score: 2, Insightful

    I always thought that the backward and forward buttons aren't very well suited for a web. I thought one could have a browser that, as you browse, keeps a little picture of a graph of the recent links followed, so that you can jump directly to a different branch, and don't have to traverse the whole tree up and down.

    It would work something like this:
    google search "best web browser arround"
    google lists a list of web sites. On the side you see a single node.
    You click on "opera". On the side you see a node linked to one node: node->node
    You click on "features. Now: node->node->node
    Now you want to see something about netscape. Click on the first node in the graph. You are back to the google page. Click on "netscape". Click on version 3.0, click on features.
    Now the graph displays:
    node->node->node
    \->node->node->node
    Now you want to compare these features to the features of opera. You just click on the last node in the first subtree.
    And so on....
    Don't you think it makes more sense?
    And it would drive all the javascript programmers, who don't even want you to use the back button, crazy - as a bonus!

  18. Re:SuSE 8.2 freezes on Review of SuSE 8.2 · · Score: 1

    It seems that this is more of a kernel problem than a SuSE problem. Did you try booting single, and see if the machine still locks up after 5 minutes?
    If yes, try to boot with a different kernel, and see if it also freezes. Maybe you can custom compile a kernel.
    If not (which also means that it might not be a kernel problem), it must be one of the programs that are started up. Try finding which it is through elimination.

  20. Here's what I do - not very elegant on Building a Better 'Mobile $HOME'? · · Score: 2, Informative

    As was pointed out already, there are two problems here - one is having a universally readable piece of hardware, and the other is how to keep configuration across different systems.
    I solve the 2nd problem by having 2 directories, called .laptop and .desktop
    and a directory called .cur_dot that is linked on my laptop to .laptop, and on the desktop - .desktop (!) .kde is linked to .cur_dot/.kde
    dot files that need to be the same on both systems sit in .common_dot, and are linked correctly. So .tcshrc is linked to .common_dot/.tcshrc
    If I really wanted, I could trace down the various bookmark and cache files in .kde and place some of them in .common_dot.
    I can thus rsync my home directory easily, just taking care not to overwrite .cur_dot
    This can easily be extended to cover several systems. I wrote a couple of things to make life easier, but overall it is quite a pain to keep track of every new dot file that a program generates....
