    Putting more applications into kernel mode is a step along the transitional path to a microkernel architecture. If things like that get popular, then Linux will evolve means to guard them from the rest of the kernel, fairly allocate resources between them, etc.

    (One path development might take is to do less checking during each context switch, and more earlier on, when the application was first loaded. If a degree of trust can be statically verified, the app can be safely permitted to run with full kernel privs. This gets into HP of course.)

    To play with the concept, here's a toolkit which allows any program to be added to the kernel.

    Don't wait to "implement". Publish first.

    If you take the time to hunt patents before you use an idea, you run the risk of delaying the publication of an idea long enough for someone else to patent it.

    If that's any kind of concern for you- if you've got a good idea, and are afraid someone else might patent it in the near future- then hurry up and publish immediately, before you even manage to write a functioning program that uses it.

    Post it on Slashdot (Off-topic). Spam to USENET (alt.sources ?) Do something to get a public record of the time you were aware of the idea. Just get it onto the internet in a place where third parties (Google's dejanews service) can, if needed, verify the time/date of your posting.

    Illegally obtained evidence can be used in US court. Sometimes. On a case-by-case basis, up to the presiding judge.

    If the illegal actions were done by police, prosecutors, or other government types, then the rule is very strict that the evidence is thrown out (as is anything else found based on that evidence- the "poisoned tree" rule).

    Prehaps that's an interpretation that has recently been applied to the UK. It must be fairly new, though. Since at least the 1600s, English Common Law has included the principle "Ignorant facti excusat, ignorantia juris neminem excurat.". Ignorance of fact is an excuse; ignorance of law is not

    Fragmentation, the basis of your wild assertion, has nothing to do with overall capacity.

    From a theory perspective, total capacity does have something to do with fragmentation.

    Assuming both drives are using the same intelligently designed filesystem (meaning it makes some effort to avoid fragmenting), and that the user creates and edits files in the same order, a smaller disk will suffer fragmentation before a larger one does.

    If a one gig disk has two files on it, A and B, and then file A is appended to be 501 megabytes in size, it will probably be fragmented. On a 10 gig drive, it may still be contiguously stored, just from natural writing.

    The only way I can think of that mattering is if it causes you to have less swap space.

    Here's another possibility: Because the data on the drive had to be compressed to fit.

    This is a common tactic for Linux distributions that want to stuff in a big assortment of desktop programs. (On the assumption that their users will be unable manage installing anything later, so they need all file-handlers present initially)

    The Knoppix live-cd is the most famous user of this technique. Knoppix provides KDE, OpenOffice.org, Mozilla, Gimp, and other large programs, but it reads them from a compressed archive that further degrades the already low read-speed of a CDROM.

    You're making me think I'm not going to like the installer

    That's a common opinion, although it somewhat depends on what you mean by "installer". The installer that initially prepares your hard drive is quite servicable (in terms of partitioning, bootloaders, etc), although not as pretty as a recent RedHat or Mandrake offering.

    However, once that setup is over, you're left with some bad options to add further packages. There is dselect, which is full-featured and informative but painfully convoluted to use. And there is apt-get, whose minimal CLI is adequate for those who can handle it, but unhelpful for newbies. An assortment of "Graphical APT frontends" have come and gone over the years, but they never manage to survive very long ("aptitude", etc).

    Unfortunately, up2date doesn't grab programs that weren't in the distrobution. :(

    In general, Debian's apt system doesn't support that either. But their larger number of packages in "the distribution" makes that less problematic. Since most users never attempt to burn a full set of discs, they have little pressure to save space by dropping packages.

    If a 3rd party developer supports it, she can provide an apt.config line to add HTTP access to auxilliary deb files via your normal apt-get routine.

    So I doubt that being two separate companies would do much for innovation, especially since each would still have the lion's share of its respective market.

    If Microsoft were split up like that, there's a freakish-sounding scenario that actually becomes highly probable:

    The application-half will try to get back into the OS market as quickly as possible, and will soon release a "Microsoft Office" CD that optionally installs a bootable image to your hard drive. How will they leapfrog over the year of time it takes to write a reliable OS? Build it on Linux, of course!

    This is reasonable, because if the companies are truely split up, then they'll have no reason not to undermine the other's monopoly position. The backstabbing will be relentless. And with Linux out there, an OS is much closer to a free commodity than Office Suites are (since OpenOffice is still a marginal competitor). So it will be the Office half, not the Windows half, that will be victorious.

    Yes, I have heard of the great "apt-get" and will definitely exercise it a bit.

    Even if you install packages from CD-Rom, you'll use the same interface as if you were getting it live from HTTP. The only difference is that it'll prompt you to insert the right disc first... and since most packages are small, it'll often take more time for you to find the disc than to just get it from the server.

    You didn't mention if you had downloaded the stable or testing Debian... testing is generally prefered, because it's not as painfully obselete. If you value stability, "stable" is good of course. But if you want to have fun and experiment, then newer is better. And if you're using "testing", then you'll probably want to keep up with changes made after the CDs were burnt. Debian "testing" CD-Roms go obselete really fast.

    I don't know why you have a problem with the naming of RPMs. I find that it is usually the same as the program or package name.

    RPM names also contain at least the version string, and often an indication of which architecture the software will run on. Sometimes supported OS versions are mixed in too. For example, when I tried to install a package on a Red Hat system, I had to download that RPM. Then go to install it, and find out I needed multiple other RPMs first, which need even more RPMs to work.

    The point of apt-get is you, the installing user, never even see the *.deb file that the package actually comes in. The hunt for dependencies is completely hidden from you.

    Of course, RedHat users can optionally run apt-get themselves, but that's not formally supported by the distribution developer.

    I won't go into the whole problem of not getting *.deb files for new, bleeding edge software. It's an accepted fact that Debian users who wish to try something brand-new will be compiling it themselves.

    Debian prides itself on an enormous amount of packages... nearly twice as many, counting bytes, as RedHat provides. To attempt to download "a copy of Debian" is wrong and wasteful. The fun of Debian comes in when you decide, on the spur of the moment, to try some exotic free software program and can apt-get it in a much less time that it would take to even figure out the name of the RPM you'd need to install on a "normal" Linux system.
