  1. Stratus x86 fault-tolerance isn't BS/marketing... on Red Hat Announces Enterprise Linux · · Score: 1

    I call bullshit and marketing.

    Well, nice try. But you're wrong. Do a bit more research.

    There are custom motherboards involved, custom low-level software involved, and I believe custom chipsets. Stratus figured that maybe they could cut their+customer's costs by using commodity CPUs (and memory and peripherals, etc) back 5-10 years ago. I'm not sure it ever sold that well because people buying million-dollar servers don't benefit that much from shaving a few thousand off the CPU. But the binary compatibility is nice.

    Also, with Itanium and Itanium 2, there is support for a lot of this fancy hardware error recovery stuff in Intel-based chipsets for the first time (see the E8870 chipset docs and look for "Advanced Platform RASUM".)

  2. Re:Red Hat is inching up on Red Hat Announces Enterprise Linux · · Score: 2, Interesting

    Or in short, all those things that make an enterprise server an enterprise server.

    Well, I sort of agree with you. However, Sun/HP/IBM were calling their Unix offerings five years ago 'enterprise' without having any of those features (even though the mainframe mostly did). I've never seen a really firm definition, although I certainly have my own views about what the phrase should mean. While I agree a bit with your point, it's also not quite fair for the 'enterprise' guys to constantly redefine the enterprise feature set to include whatever the low-end guys don't have.

    You may of course disagree. The important thing is recognizing what Red Hat's enterprise solution does and does not provide.

    The real question to me is, do Red Hat's 'enterprise' enhancements effectively help Linux extend dominance beyond the web-server niche which Microsoft can, should, and will try to position it into. (Promptly before Microsoft offers a low-cost version of NT server with IIS-only.)

  3. Red Hat is inching up on Red Hat Announces Enterprise Linux · · Score: 5, Informative

    Red Hat has definitely been inching up the scale.

    Journal filesystems hitting maturity, logical volume management, asynchronous I/O for the database guys, TPC-C benchmarks (unaudited though?), improved clustering

    There are still things Linux lacks (last I checked) that the conventional UNIX vendors have added to their systems over the last five years: things like hot-swap memory, hot-swap CPUs, memory failure resiliency (OS quits using memory if recoverable but warning-sign single-bit ECC memory errors get too great), kernel hot-patching, multipath IO, workload management stuff, and ever-more SMP/NUMA scalability.

    Still, seems like Red Hat is making great strides. Hat's off! (ugh, sorry about that, couldn't resist. ;-)

  7. A defense of Unix... on Technologies that Have Exceeded Their Expectations? · · Score: 1

    I pretty much agree; I've never been too impressed by the chasing-taillights feeling I get with Unixes and the user interface. The commercial Unixes gave up on the desktop around 1993 when NT showed up on the scene, and while there was a resurgence of interest and improvement in the desktop with Linux vendors, there's still a long way to go. I've always been amazed at how simple things (like changing one's screen resolution) end up being hard to figure out how to do until you memorize various pseudo-obscure steps.

    Still, I think you are selling short the contribution of UNIX in a couple areas at least: the web and XML.

    Unix tools for accessing information have improved dramatically over time culminating in the web. I consider this a major advance, separate from the GUI. While we could argue to what extent it was a Unix vs. NeXT vs. Windows innovation (certainly it has since been coopted by Windows), it was very much a UNIX phenomena when I opened my first web browser Xmosaic back in 1993, and I think Unix deserves some credit for giving birth to it... the development linkages between TCP/IP protocols, the servers and clients on either end, and Unix are deep.

    And as for XML, it seems to me to be as Unix-y an approach to the web as possible, taking Unix pipes to their logical extension: taking human readable/editable flat files and passing them between programs to manipulate data in a flexible and powerful way. As a user and a developer, I still don't think the promise of XML has fully been unleashed (it takes a lot more than a little | symbol...), but I do think its buried in there somewhere.

  8. What does Intel have to say? on SCO Sues IBM for Sharing Secrets with Unix and Linux · · Score: 1

    When asking "who is going to win this case", a key question we might see answered before the full trial would be "whose side is Intel (i.e. their developers, experts) going to testify on"?

  9. SCO's claims don't pass the sniff test on SCO Sues IBM for Sharing Secrets with Unix and Linux · · Score: 5, Insightful

    At least some of the claims just don't pass the sniff test.

    When AIX came out in 1990 or so, it was so different from SVR4 that competitors cried "AIX isn't UNIX". IBM really did a huge amount of kernel work and had all sorts of administrative features borrowed conceptually from the mainframe that were lacking in UNIX at the time. Journalling filesystems, logical volume management, etc. just for starters. The toolset for managing AIX was (and still is, to some extent) quite different from other UNIXes. I think IBM kept the SVR3/4 APIs but re-wrote
    most of the code below it back in the late 80s.

    You know you have a weak argument when you start seeing claims like this:
    Added Sontag [SCO SVP], "When they (IBM) started utilizing the same engineers that worked on the Unix System V source code and the ultimate derivative of it in the form of AIX, they have
    effectively been applying our methods and concepts, even if there isn't a single explicit line of code" that shows up in Linux.


    Believe me, there are a lot of methods and concepts that UNIX (System V/VII,SVR4) stole from predecessors, and continues to steal! Where's the suit from the MULTICS guys against AT&T? Citing executive's handwavings generalizations about leveraging UNIX expertise makes for a pretty weak legal case (and PR case imho). Monterey always had too much hand-waving for me to get enthusiastic about.

    However, the issue of IBM allegedly re-creating versions of SCO libraries using SCO's actual code sounds interesting. SCO binary compatibility is actually something somewhat valuable that SCO should fully defend if it was unlawfully infringed upon via trade secret leakage rather than cleanroom reverse engineering. Still, if I remember correctly, most of the SCO/Linux binary compatibility stuff was done by some guy at SCO (Avi Tevananian or something like that? I'm butchering his name, sorry.) SCO was working on Linux binary compatibility before IBM even knew Linux existed. So to speak.

    As far as infringing on how to run Linux on Intel, clearly Linus managed that without anyone's help. Now running Linux on IA-64, or perhaps some particular acceleration technique used by SCO might be grounds for a decent case depending on the particular evidences involved. I guess we'll see.

    With revenues less than Red Hat, and a business model going nowhere, a legal approach makes sense for SCO. IBM can afford the lawsuit and probably route around it better than, say, Intel could route around Clipper chip infringements in existing products. If it lays clearer guidelines for Linux IP, so much the better. I guess that's what I'm hoping for. As a betting man though, I wouldn't bet on SCO for this case. Unless there are more rabbits in that hat.
