  1. Re:Itanium2 on Why Doesn't the Itanium Get the Respect It's Due? · · Score: 1

    > The VLIW architecture is beautiful in many ways,

    That is true. It is similar to RISC, but it makes more efficient use of execution units and code size. However, in one aspect VLIW is even worth than RISC: the predicted efficiency is only realised if the ISA matches the CPU architecture. Otherwise, a translation layer is required, and the main advantage against CISC evaporates.

    Sun had big troubles with than on SPARC. The ISA worked well for the SPARC processors in the early nineties, but it is difficult to execute efficiently on a modern CPU.

    I am sure that Intel ran into that problem when designing new revisions of the Itanium, and eventually it is doomed. The marked place just doesn't permit to change the ISA with every CPU architecture, binary compatibility is to important for that.

    So: ISA does not matter for efficiency, unless you want to recompile your apps for every new CPU. And most people don't want to do that for a meager performance advantage.

    Actually, it is. The standard was updated in 1998 to avoid confusion (Standard IEC 60027-2). Giga is 10^9, and it is constant, which means it does not change just because you use it for hard disks or memory.

Conspicuously absent in nature, if you ask me.

    On the other hand, you find oddities in nature that are very difficult to explain without evolution. Take the wing of a bird, the leg of a dinosaur and the human hand, they all have the same basic topological features (not dimensions, of course). Since they have a completely different purpose, this could not have happened by design.

    Or what about the wheel? The single most important design idea. It is completely absent by nature, because it cannot evolve (easily) by evolution. Just imagine wheel and bodies evolving along different lines :-)

    > And now it is my turn to disagree. When you start talking about the enterprise, a whole different set of rules come in to play.

    Yes, but you are confusing to different situations: running an old server with Debian Woody, and installing a new server with Debian Woody. Since servers have a (hardware) lifetime of about 5 years, it makes a lot of sense to run the same software release on it for this time. You might do a mayor update if you need to, but usually you would just do security fixes. That's why you see lots of RedHat 8, Solaris 5.6 or Windown NT 4 around.

    However, for new machines the picture is completely different. Getting hardware that runs NT 4 is nearly impossible, which is why every enterprise that does not have a clear migration strategy by now has a serious problem. Debian Woody is similar: finding a recent machine where you can install Woody is probably a challenge (think graphics card on the desktop, and gigabit ethernet/RAID/SATA on the server side).

    So Debian is fine for machines that you installed 2 or 3 years ago, but it is not at all a possible choice for a new machine. Which, incidentally, completely defeats the purpose of stability.

    The same as always: software aging (also termed "bit rot"). Look at woody (the last release), and you know what is wrong: standard kernel is 2.2 (therefore no support for most USB devices), XFree version 4.1 (good luck finding a graphics card that is supported), mozilla is version 1.0, openoffice.org is not even included, and KDE is still stuck at version 2 (which conflicts with version 3, so that you cannot run *any* KDE 3 application).

    So whatever happens to sarge, it is going to be *way* to late. Plus sarge is not nearly up to date either. It is still based on XFree 4.3, and has no support for amd64. Which means it will be obsolet way before Etch can possibly be released.

    It is a shame, because apt-get is so much superior to any rpm based solution I have seen. But unless you can run testing, Debian is not really an option on the desktop.

    That is the basic problem of deinterlacing. You want to increase the vertical resolution for stationary scenes, and the temporal resolution for fast moving scenes. It can be done, but it involves a lot of guesswork, and it can produce artifact.

    So for most applications, scaling up half images is a very reasonable solution. If you care about vertical resolution, you should not use an interlaced signal in the first place.

    I absolutely agree. What's more, development seems to come to a standstill (a bit like TeX, really). Remember the weird Staroffice 4.0 for Linux? It was emulating a complete Windows desktop. And I could bet all that code is still in there. E.g. Openoffice has its own font rendering, which again is arcane: it cannot even do subpixel rendering.

    And so many features are still missing or not really working. Try to get multi-level section numbers (1.1, 1.2 etc), it is a pain, and simply does not work properly. Try embedding a dia diagram, and again it seems mostly broken. The PDF export creates wrong logical page numbers, and the TOC is not even hyperlinked.

    And now they announce 2.0 as the great new release, but they have to resort to features like "count the words in the selection" as mayor improvements. Man, that is a feature I would take for granted. I wonder whether printing from the command line will finally work. Oh, and whether rtf export/import will keep my document intact, or still garble it up.

    No, the codebase of Openoffice seems to be hopelessly bloated. It can do a lot, but you can't teach it any new tricks. It is doomed, I am sure. Maybe koffice will do better.
