  1. At spec.org on Red Hat/Apache Slower Than Windows Server 2003? · · Score: 1

    you have to go back to 2nd quarter 2003 to find a hardware vendor using IIS. Intrestingly, that vendor was Dell showing off a PowerEdge 2650 running IIS5 as well as Rehat Linux 8 (link http://www.spec.org/web99/results/res2003q2/). On this hardware, IIS perfomed 3% better than RHCA (TUX) on Redhat Linux. So, if speed is what you want, hardwave vendors have given up on IIS about two years ago. If features is what you need, then it seems Apache is the choice. Seems to me, IIS has no role to play any more. There's always a better and cheaper choise elsewhere.

    "A compromise would be four small conventional motors driving the wheels through stub axles."
    Yes, that is a much nicer solution.

    The clutch would not serve the purpose it does in conventional cars. You would only use it if you'd like to stop your wheels instantly (or as quickly as possible). Most drivers wouldn't want to do that but some whould.

  5. Re:Wheel motor is a bad idea on Aircraft Maker Will Produce Electric Cars in 2006 · · Score: 1

    Yes, I did. There is a rotating permament magnet which rotates at a large radius. This is incidently the good thing with shafts. A hollow shaft can transfer large tourques while still having a low mass low moment of inertia.

    And, you don't have to have allt that much higher if you hide inside your car. It will be higher though since you need to leave some room for suspension.

  6. Wheel motor is a bad idea on Aircraft Maker Will Produce Electric Cars in 2006 · · Score: 4, Informative

    The wheels will be too heavy and add kinetic energy of the rorating mass. It will require more breaking power and will be slower to react on the controlls. I say, put one sufficiently large electric motor where it can be cooled and distribute that power the traditional way. This looks very nice in theory but drivers will no like this concept. A normal wheel is heavy as it is. Permanent magnets can not be made light and they will require volume. The magnet height along magnetic lines acts like a source and the air gap as a resistance. Those things add up to a heavy fragile (alt. inefficient) design. You'll crash that engine the first time you run over a curb at 30 mph (or forget low-profile tires).

    A single electric motor inside the car can be isolated from road vibrations and shock. The motor can optimized with fewer requirements and a traditional clutch can isolate the wheels form the kinetic rotation energy of motor (when required).

    In this increasingly mobile world, you still can't roam the desktop (meaning disconnect the desktop and reconnect to it somewhere else). Even using a T1 and LBX (low bandwidth X) you have to be pretty patient in addition to slightly humiliated when you see Windows Terminal Server users do the same stuff using a regular phone line and a modem. It's sad considering that the rest of the technology has so much to offer.

  9. Re:kernel on Intel C/C++ Compiler 8.0 Released · · Score: 5, Insightful

    To tell the truth, not even all gcc versions are compatible with the specific version of gcc that is currently supposed to compile the kernel. Gcc compatibility is a moving target and kernel developers do not switch to the latest gcc version as soon as it appears. Examples of this are kgcc vs gcc in some distributions. Unless icc becomes the official compiler for the linux kernel, I doubt it will ever compile the kernel in a predictable way (what ever predictable means in this case). /jarek

  12. Re:ReiserFS on Tom's Hardware Looks At WinFS · · Score: 1

    I'm sorry, but ReiserFS is a meta-data journaling only file system. This means that it does not protect your data at all. It only protects the integrity of the file system. This goes for other journaling file systems like NTFS and XFS. Ext3 is somewhat different in this regard as it can be made to do data journaling as well as meta data journaling depending on mount options.

    The problems with ReiserFS 3 are not all that unknown. If you ever found files on your system that contain junk appended to the real data you've found a known problem with ReiserFS. I believe that this has actually been solved in later kernels but the solution was not part of 2.4.0 for sure. /jarek

  14. A prediction on SCO Might Sue Linus for Patent Infringement? · · Score: 1

    As much as I'm tired of predictions made on the internet, here's one. SCOs shares drop below $1 within two weeks. Owners of SCO shares sue Mr. McBride for fraud with proof that he knew there was no case to begin with based on the letters sent to Novell. Microsoft requires their money back (which at $1 would match the market value of SCO) and SCO goes chapter 7 immediately. IBM picks up the remaining pieces to avoid that Novell get the rest Unix ip/licensing/copyright assests.

    I have to admitt, 100%, with the author of the article. The feeling I have nowdays is that when the VC are in over 50% of the company, the company is lost. They will drive the company to its knees and force the orignal enginners out. All that without really wanting it, just by pure incompetence or ignorance. The VC (pet) CEO will be changed within 12 month when, accoring to plans, the company has outgrown his set of competences (allthough not much may have changed in the company). They have no eye for talent since they really don't care for technology or development. The product is the company, not the technology put into to product of the company. Once a structure reminding of a company has been created it is due for introduction to more traditional investors that may buy the company on the basis of "track record" and build up of market presence.

  24. Re:Linux is not a contender.. on Broadband Crackdown · · Score: 0, Offtopic

    If you put Linux next to some other operating systems out there for a cost comparison, the conclusions are devastating for Linux.

    Wrong!

    Linux costs not only more because of the frequent updates which require new cdrom's to be bought.

    Wrong. Patches can be downloaded from the internet.

    Another factor in Linux cost is its maintenance. Linux requires a *lot* of maintenance, work doable only by the relatively few high-paid Linux administrators that put themselves - of course willingly - at a great place in the market. Linux seems to need maintenance continuously.

    Wrong! I'm not a high paid Linux administrator and I can maintain my linux computer easily.

    Add to this the cost of loss of data. Linux' native file system, EXT2FS, is known to lose data like a firehose loses water, when the file system isn't unmounted properly. Other unix file systems are much more tolerant towards unexpected crashes. An example is the FreeBSD file system, which with soft updates enabled, performance-wise blows EXT2FS out of the water, and doesn't have the negative drawback of extreme data loss in case of a system breakdown.

    Wrong. I have used EXT2FS since 97 and still not lost any data. Allthough I have to say that crashes have be so infrequent that the recovering features of ext2fs has not been put to the test very frequently. If you want higher file system integrity, you can use several available journaling file systems, some of which offer better performance even compared to freebsd.

    Factor in also the fact that crashes happen much more often on Linux than on other unices. On other unices, crashes usually are caused by external sources like power outages. Crashes in Linux are a regular thing, and nobody seems to know what causes them, internally.

    Wrong. Linux has a reputation of stability

    The steep learning curve compared to about any other operating system out there is a major factor in Linux' cost. The system is a mix of features from all kinds of unices, but not one of them is implemented right. A Linux user has to live with badly coave low performance, mangle data seemingly at random and are not in line with their specification. On top of that a lot of them spit out the most childish and unprofessional messages, indicating that they were created by 14-year olds with too much time, no talent and a bad attitude.

    Wrong. Linux is very much comparable to other Unices in terms of learning curve. Most distributions have extensive howto's and man pages. Learning curve is highly individual, your milleage may vary.

    I can go on and on and on, but the message is clear. In this world, there is no place for Linux. It's not an option for any one who seeks a professional OS with high performance, scalability, stability, adherence to standards, etc. The best place it should ever reach is the toy store, and even that would be flattering

    Right, you can go on and on but, from what I can read here, you will be wrong all of the time.

    Have a nice day!
