  1. Re:MOD PARENT TROLL on Your Favorite Math/Logic Riddles? · · Score: 1
    There is one problem with the question as stated.
    The king will call the prisoners in any order he pleases, and he can call and recall each prisoner as many times as he wants, as many times in a row as he wants. The only rule the king has to obey is that eventually he has to call every prisoner in an arbitrary number of times. So maybe he will call the first prisoner in a million times before ever calling in the second prisoner twice, we just don't know. But eventually we may be certain that each prisoner will be called in ten times, or twenty times, or any number you choose.
    Say the king needs to call each prisoner at least ten times. What is to stop him from calling prisoner #1 ten times, and never again, then prisoner #2 ten times, and never again, etc.? If the king does this, then prisoner #1 is never able to send more than 1 signal. Or the king can start off by calling the counter ten times, and never call him again. In this case, the counter will never be able to receive any signals.

    The question should probably say instead something like: "with n_i being the number of times prisoner #i is called, n_i/n_j approaches a non-zero constant as time approaches infinity, for all pairs i and j."

    Sun requires you turn your copyright over to Sun.

    The FSF also requires you to assign your copyright to them if you contribute to some of their projects (such as emacs -- I know; I've contributed to emacs). And you have to sign a document saying that your work is your own, and that you have the right to assign copyright to them (i.e. your employer has no claim over the code). This is to make sure that any code that goes in is legit, or at least that if they get sued for copying someone's code, they can point to the document and say that it wasn't their fault.

    Of course, the free software community trusts the FSF a lot more than than they trust Sun.

    Creative Commons has been working with debian-legal on making the appropriate licenses DFSG free. I don't know how much progress has been made, but there is something being done. So as long as the icons are licensed under CC-SA 2.0 "or later", things should work out eventually. Although I think it would be good for them to dual-license under both CC-SA and GPL.

    Since Reiser4 is not in mainline kernel yet, you need to compile your own kernel (either use the -mm branch, or download the patches from the Namesys web page, or wait for Reiser4 to be added to mainline). Of course, this also means that you need to do a little bit of swapping in order to use it as your root filesystem, since no distribution offers it by default.

    I don't know about the GP poster, but I use Debian, which includes the Reiser4 utilities.

    Sure, ReiserFS is a full blown filesystem, and WinFS is not a filesystem, however the functionality of WinFS is included in ReiserFS.
    To be more precise, the functionality of WinFS is included in what ReiserFS will be able to do when it is completed. As of right now, Reiser4 is just a normal storage system with no capabilities above the other filesystems that are included in Linux (ext3, JFS, XFS, etc.) In a few years, we will have what is currently referred to as Reiser6, which will have the extended semantics that has been in planning for over 10 years. But it is not there yet.

  11. Re:Kernel vs User Mode for filesystem on Interview With Reiser4 Author Hans Reiser · · Score: 2, Insightful
    The problem isn't that Microsoft is using a microkernel (which they aren't, BTW -- at least not the last I heard). It's that WinFS is a separate library that sits on top of the storage layer. This means that programs must use a completely different API to access WinFS, rather than just using normal filesystem calls.

    You also seem to be mixing up the issue of microkernels and monolithic kernels. Apple's OS X uses a microkernel, but the operating system is still monolitic, so all the important stuff is still part of a single big process; the microkernel is basically just an abstraction layer. Hurd is a microkernel but uses multiple servers, so all the subsystems are separate.

    And /. is not one monolitic entity either.

  12. Re:When will it be "safe" to use? on Interview With Reiser4 Author Hans Reiser · · Score: 2, Interesting

    Many people (including myself) have been using Reiser4 for quite a while now without any problems. The developers have stopped being able to find bugs, as far as I've heard, although the occasional bug does pop up on the mailing list (and is fixed rather promptly by the developers). When Reiser4 gets included into the mainline kernel and the number of users increases by an order of magnitude, it will be likely that some new bugs will be found. I might not trust million-dollar, mission-critical data on it just yet, but for personal use, it seems to be stable enough.

  13. RTFA on Interview With Reiser4 Author Hans Reiser · · Score: 1

    Eventually, Reiser4 will allow storing metadata in plain old files, so that no special tools will have to be used. It will also allow queries done straight through the filesystem. In the interview, Hans says that that functionality is about 3-5 years away when fully implemented, but it will be implemented gradually, so some functionality will be available earlier.

    Where did you get 26.4% from? They looked at 49 studies. 45 of them reported that intervention was effective. Of those 45, 7 were subsequently contradicted, and 7 were found to report stronger effects. So that's 14 that are "inaccurate or overblown". 14/45 (which follows the percentages given in the abstract) is 31% (which is pretty close to 1/3). If you want to do 14/49 (the total number of studies they looked at), that gives you 28.6%.
