  1. Re:s/GPL/BSD/ on HP Calls For Sun and IBM to Remove OS Licenses · · Score: 1
    If you want to see it improved and become something greater than one man's labour, use the GPL, because that's the only way you'll ever see the improvements.

    There is no requirement in the GPL for modifiers to give modifications back to the original author.

    All it requires is that recipients of the modified version get the modified source (or an offer to provide the source) used to produce it.

    So if someone modifies your GPL'ed program and no-one ever gives you a modified copy, you'll never see those changes. IBM, Apple, Netscape and Sun have tried "give us all your changes" licenses, and they were lambasted for doing so.

    I'm sitting on a number of modifications for CVS and GNU Make, which I'll never send back into the maintainers. But everyone with access to the modified binaries can also get at the corresponding source.

    These changes don't make much sense outside of my particular company--changes that are "good for the world" I send back upstream, but that's because I want to help others, not because the GPL requires that I do.

    That's due to losses in a conductive medium, known as the "skin depth effect". Longer waves have a deeper skin depth, so are carried deeper into a conductor. (Salt water is approximately a conductor.)

    In the opposite direction, very high frequencies use only the surface of a conductor. Consequently, microwaves aren't run on wires, but are actually sent down hollow "wave guides". If you need any sort of power, you'd need a massively thick wire, but the energy will just be on the outer surface. So we use a tube, the waves don't care.

    Tesla coils use this effect for rather dramatic results.

  4. Re:Force? on Digital Cameras Force Film Off Dixons' Shelves · · Score: 1
    A landscape photographer friend was outgraded when I mentioned that I could get 600-800 shots on my Digital Rebel XT/350D, when using the battery grip and both batteries. (The camera is so light, I just leave the grip on so it balances on the strap better.)

    He said he gets 5-7 years out of a single battery on his T90 film body.

    What he didn't take into account was:

    • The Digital Rebel XT is the hobbyist camera, the 20D has a much larger capacity battery.
    • His battery doesn't get to run any autofocus motors--not a big deal for landscapes.
    • His doesn't run the flash either--also not a big deal for landscapes.
    • Most importantly, his doesn't have a computer that's trying to digest 3 x 8 millon dots, and write it out to a flash card.

    So, like you hinted, you have to compare battery + card use on a digital camera to battery + film use on a film camera.

  5. Re:Welcome to 1986 on Apple Releases Multi-Button "Mighty Mouse" · · Score: 1
    I think this is a very weak argument. No one with more than a few days of computer experience has the slightest trouble with multi-button mice.

    This is patently wrong.

    People who "are into" computers quickly grasp hold of select/execute on left and menu on right (Windows, OS/2, Amiga, OS X), or select, paste, and extend (X11), or select, execute, menu (Xerox Star, IIRC), or a polybuton chording system, or whatever else floats their UI boat. USB Overdrive and other multi-button interfaces (especially from Kensington) have been around for Macs for ages. People who know what they do love them, and people who have no idea what you're talking about with all these context menus can live without them just fine.

    People who don't "get" computers are always asking me, "Left or right click?" They haven't noticed the pattern in the chaos of clicks. Many of them still don't understand the difference between double-click and single-click... and it doesn't help that some things execute on a single click (like hyperlinks), and some select (text regions, icons in the Finder)... and even then they haven't noticed that "double click" means "do the most common or default action on the thing".

    Apple's breakthrough wasn't in getting rid of the menu button, that's easy--just remove context-sensitive menus and put them on a fixed place on the screen. Merging "select" and "execute" is what took the brainstorm of using double-clicking.

    And we've had to be telling people, "No, just click once!" ever since.

    Finally, keep in mind that intermediate and expert users are probably less than 25% of the computer-using population. So a default appropriate for 75% is just fine, Apple has allowed people to plug in other vendor's mice with more buttons ever since the ADB Macs came out.

    OK, Mac OS X is quite happy with FAT16, FAT32, HFS and HFS+, and maybe that UFS thing I've never used but can choose in the formatter.

    I've never tried NTFS on it; but trying to work NTFS on non-NT-based systems is awkward at best--though it is definately better in the newer Linuxes.

    Let's face it, we're still pretty much stuck with FAT32 for cross-platform filesystem interoperation, even if you aren't using Windows. And every camera is using it, or at least FAT16, for the flash cards--it may suck, but it's a known system, and everything can deal with it.

    Or, perhaps, someone can tell me how to get XP SP 2 to do any of the following:

    • Sort directories with all other file types
    • Show all files in a directory, rather than just the ones that match some magic pattern
    • Separate file name from file type
    • Use an menu accelerator key that's close to the space bar, rather than near the edge of the keyboard

    OK, on that last one, tweaking the keymap would do it. (And that would solve the article's author's problem with Command vs. Control--swap Windows and CTRL on his Winbox keymap, or Control and Command on his Mac.)

    And I don't want stuff that only works for the current load/save dialog, like switching to list view. Yeesh.

    Those would be where we can predict the existence of an element, but haven't found or synthesized one yet.

    For example, if you have a set elements with nucleuses containing 1, 2, 3, 4, 5, 7, 8, 9 and 10 protons, you can guess that there should probably be one with 6 in the bunch.

    Electron shells are related to these predictions, too; we know how many electrons can be at particular "distances" from the nucleus, so if we have elements with incomplete shells (== room for more electrons), we can predict that there are elements which have complete shells.

    Since the periodic table is ordered by protons-in-nucleus-count, and grouped by electron shell number, drawing out the periodic table inherently makes those predictions.

    Intel is not detecting the supported instruction set, they are detecting the actual CPU.

    The way a responsible compiler developer generates code in this situation is to say, "I need feature X, Y and Z for this code path--it will be used if all are present."

    The only thing the latest Pentium IVs have on the Athlons is the SSE3 extensions, and that is pretty much irrelevant to most code. "It must be true, Intel told us."

    If you switch the Intel compiler so that it does NOT generate multiple-CPU-supporting code, you can generate code that runs on Pentium III, IV, and Athlon just fine. (My overly-cheap ECS Duron board burned out, and who cares about Duron anymore anyway?)

    (The magic switches are -xK or -xW, BTW.)

    But there is no reason for code targetting a Pentium IV restricted to SSE2 at the highest to NOT run on an Athlon. You can "not support" it, sure, but to DELIBERATELY disable the code when you detect a competitor's chip is... well, anti-competitive.

    And this isn't a free compiler. You pay for ICC. (There's a for-free-software download, sure, but most people who really care about this stuff are more than willing to pay, and pay well, for the best compiler optimizations they can get.)

    The problem is not that they can't guarantee that the AMD chips work. The problem is they are generating instruction streams that run JUST FINE on AMD chips and their runtime code DISABLES that code path (if you use the recommended or default compiler settings).

    It's AMD's job to make sure their implementation of IA32 + whatever extensions is good, not Intel's job to disable code on their chips--except based on the processor capability word. (Whatever "flags" from /proc/cpuinfo is properly called.)
