  1. Has someone actually read about or used it ??! on Does Linux "Fail To Think Across Layers?" · · Score: 4, Informative

    <OT>
    As an older slashdotter, I am quite disappointed with the discussion so far. A few have suggested to discuss the topic in question, respectively ZFS. But, as so often, we can make out that people just blindly speak without having read neither the original article, nor about ZFS.

    </OT>
    ZFS solves about all and any problems we have had with filesystems since FAT, and this same community was pretty enthusiast in http://developers.slashdot.org/article.pl?sid=05/1 1/16/2036242.

    Most of all, to me, I am astonished that almost everyone talks 'virtualisation', VM, QEMU, Xen.
    When it comes to filesystems, suddenly many seem to want to do everything on their own, on physical platters: partition, volumes/RAID, format. ZFS is a virtual filesystem, where none of such is physically needed. There is a nice http://www.opensolaris.org/os/community/zfs/demos/ basics/ demo on how to create 100 mirrored filesystem within 5 minutes.

    Of course, filesystem should be a black box, an object, instead of the user having to do low-level work. ZFS provides this, and more relevant: of course it needs to be cross-layered therefore.

    Snapshots ought to be available easily, at any moment in time, without taking much space. ZFS does so, by only storing the changes and sharing the unmodified data. If you want to do so, you need an abstraction of the hardware. That is, crossing layers. Not to mention writeable snapshots.

    Adding new drives without partitioning, slicing, formatting. Just adding to the existing pool. Inclusive striping being adapted automagically. This needs a cross-layer interface, right ?

    The transactional filesystem guarantees uncorrupted data at power failures and OS crashes. If you do this across a pool of physical platters, you need operations across layers.

    There is an interesting blog on the usage of ZFS for home users. It contains some good arguments, why ZFS is useful for Linux' Desktop Stride. You find it here: http://uadmin.blogspot.com/2006/05/why-zfs-for-hom e.html

    Last ot least, the online checking of all your data ('scrubbing' and 'resilvering') is a valuable feature for Linux (and the home user) as well.

    To me it looks like, as of today, that about everyone liked the features of ZFS. Now, as it requires to break some old habits, suddenly we resist change and rather stick to older concepts.
    As if GPLv2 vs GPLv3 was not enough of a threat to Linux, now we unashamedly permit a new-from-the-bottom-up filesystem to overtake us as well ?

  12. Re:Concise explanation? on Supreme Court Weakens Patents · · Score: 1

    We will have to see. There is new case law to be established. At first glance, this part of the second decision sounds quite orthogonal to what we have had to read before:

    When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill in the art has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense.

    That is quite remarkable, considering that the invention consisted of replacing a mechanical transfer of throttle (pedal position) by an electronic sensor. Something like this used to have good chances for success before. On the silly reasoning that electronics has less wear and tear it could be considered 'advantageous' and non-obvious.
    With this decision Supreme Court defined that combining an existing system (pedal) with an electronic sensor as 'normal', 'non-inventive'. It explicitely (and I guess intentionally) used the term 'anticipated success', effectively removing hindsight as argument for non-obviousness; as long as the outcome remains 'expected' and does not yield non-anticipatory results. Like the system prducing sliced bread miraculously as well ... .

    And the USPTO will sweat about getting the new stand into their guidelines and procedures.

There is so-called production pressure, meaning your promotion goes with the number of cases, not necessarily with the quality.

He might have rather shown a brave face, and rejected for sanity instead of being convinced of his success.

    As former patent examiner I am appalled that something like this was granted; or had to be granted:

    Claim 1. A method for generating a computer application on a host system in an arbitrary object framework that separates a content of said computer application, a form of said computer application and a functionality of said computer application, said method comprising: creating arbitrary objects with corresponding arbitrary names of various object types for generating said content of said computer application, said form of said computer application, and said functionality of said computer application; managing said arbitrary objects in an object library; and deploying said arbitrary objects from said object library into a design framework to create said computer application.

    This grants the patent owner all rights to royalties to a system that any third party brings to the market within the time frame of validity of this patent, and that uses this method.
    In technical terms it is obvious; and probably anticipated a few hundred times. In legal terms this is different. As patent examiner you'll find yourself in a quagmire: you may have prior art for the concept, but not for the wording. I agree, that anticipating the concept should be enough. But the vultures of lawyers will pull you apart within minutes, and the chambers and courts of appeal will usually folllow (and your bosses rebuke your rejection of the application). You will be asked for a document to anticipate the wording, and that might not exist.
    Only in high-profile cases will the parties drill down to the concepts. Why ? Because that is very costly, and if nobody forks out these costs, the average examiner will have to grant.
    Of course, the wording is overly broad. But try to cite a 'library' against it: would it be a 'object library' ? Is pulling in a function ('printf') pulling in a function of a 'object library' when C is doubtlessly not object oriented ? Let us continue with the 'object framework'; more so one that separates: content - form - functionality. Where in the 'prior art' cited here can we make out 'various object types' (not one, that is !). How do you anticipate the 'managing ... objects ... in a library'; as well as 'deploying ... objects ... into a design [!] framework' ?
    FYI: All this would have to be anticipated in a (usually) single document, before October 1, 1999.
