  1. Re:Need LILO for VMWare on The Boot Loader Showdown · · Score: 3, Informative

    Boots to a fun error message?

    Would this be error 18? How large is your partition?

    The quick fix for this is repartitioning so that /boot is small and the first partition on the disk, then it will work fine. I use Grub to boot SuSE 10 with VMware on my system at work (where Windows is the corporate standard). If this is not the fix, try Google - it's your friend.

    Combining a single-core and a dual-core on a 2-socket motherboard?

    Yes, it might be asking for trouble, but they're doing it because they can. They're nerds, that's what they do. Maybe they shoulda dumped it in liquid nitrogen or put together a cool case mod...

    On a more serious note, I worked with an outsourcing provider once that charged us per CPU, using tiered pricing for 1-3, 4-8, 9-15, etc. So, we actually asked a manufacturer if we could buy some 3-way systems.

  3. What the airlines really have... on CDC Wants to Track Travelers · · Score: 1

    Actually, when you book with a travel agent the airlines often don't have your phone number and contact information. The agencies are (rightly) afraid of airlines contacting you directly and stelaing you as a customer. So, they buy PC software that keeps all that stuff on their desktop and puts the agency's phone number in the reservation. It's often the same for online agencies (web sites), some put all your info in the reservation, many don't.

    When you fly international, the airlines will then ask for emergency contact info when you check in. They also want your passport info as they can't trust the agencies to get it right. Guess who pays the fine if you're refused entry when you arrive at customs on the other end of your flight?

    Now, while I am not a history major (IANAHM), I seem to recall something about some scientists at a large scientific facility (CERN) that invented this web thingy to exchange scientific data in a timely manner. And, since necessity is the mother of invention, the journals were'nt filling the need of the consumers (scientists).

  5. Another solution on Ergonomic Mice Reviewed · · Score: 2, Interesting

    If the glucosamine and chondroitin don't work for you, there are therapies that will. Active Release Technique (ART) is great for RSI and other repetitive injuries (I'm a runner and triathlete, I've used ART to treat various problems).

    The company where I work has an ART practitioner come on site 2 mornings a week to treat RSI and other problems. Several of my friends and colleagues have been rteated on site. It's a pretty cool benefit.

    BTW - I don't do ART for a living, I'm a programmer, so don't consider this an advertisement.

  6. Re:Great AMD is quit is doing fine. on Big-Iron to Open Up for AMD · · Score: 1

    So where I can buy the AMD server with near full redundancy?

    You don't, you buy two.

    Or atleast AMD computer with SINGLE memoryspace atleast 1TB in size?

    Two thoughts on this. 1. It's really, really expensive. 2. The mainframe assembler from the 60's or 70's is 24-bit or 31-bit addressing at most, 1TB or RAM won't help you.

    Only problems outside of box, like earthquake or something similar could bring it down.

    Now you put the second one 1000km away.

    BTW - I've replaced IBM mainframes with clusters of 4-way Opteron servers, so I know this works. And, over time, it will work more and more.

    Vlad,

    We went from HP rx5670, 4x1.5GHz Itanium 6MB cache to HP DL585 4x2.2GHz Opteron.

    Out of ordeer execution is just speculation on why Opteron is faster, but it was definitely 2x on our app.

    I've talked about this publicly, here's one link and a quick search on Google might find more details on what I've been up to :-)

    http://www.amd.com/us-en/Corporate/VirtualPressRoo m/0,,51_104_566~91665,00.html

    An important point - open source is what let use chase Moore's Law and use the fastest stuff out there. If someone comes along and knocks AMD off the top, we can move there pretty rapidly. We don't need to wait for a bunch of others to port the OS, the middleware, etc.

  8. Re:AMD could actually lose this one - maybe not on Intel/AMD Battle Rages On · · Score: 4, Informative

    We have a bunch of 4-way Itanium systems running as servers, we tried out 4-way Opteron machines about 18 months ago and they were twice as fast on our app. We've bought a couple of hundred 4-way Opteron boxes since then and we're very happy with them.

    Our code is branch intensive with low cache locality. Since Itanium can't handle out-of-order execution, memory stalls kill it, hence the need for a giant cache. Intel's compiler didn't help, we mucked with it for months. For Opteron we used gcc, compile and go, took about a day to move 500K lines of C++.

    Intel could only win this on hand-coded floating point.

  9. An observation... on 'Design Patterns' Receives ACM SIGPLAN Award · · Score: 4, Insightful

    "Some is good, more is better, and too much is just about right."

    - This mantra is good for money, horsepower, disk space, but not design patterns...

    When somebody starts telling me that they used 5 different patterns in their program and they're proud of it - then I know the code is crap. Most of the pattern zealots I've seen write bloated, inefficient code. Sometimes I think they scour the literature looking for some extra patterns to put in.

    That said, these patterns do exist and programmers keep reinventing them. The key is knowing when to call it a pattern and go to the trouble of formalizing it versus just writing code. Alternatively, find a language that makes most of these go away.

  10. OLTP systems on SW Weenies: Ready for CMT? · · Score: 2, Informative

    Now of course, the room was full of Sun infrastructure weenies, so if there's something terribly obvious in records management or airline reservations or payroll processing that doesn't parallelize, we might not know about it.

    Well, since I work in airline reservations systems, I'll add my $0.02 worth...

    Most OLTP systems will benefit from CMT and multi-core processors. We had a test server from AMD about a month before the dual-core Opteron was announced, we did some initial testing and then put it in the production cluster and fired it up. No code changes, no recompile, no drama.

    IMHO, the single-user applications, such as games and word processors, will be harder to parallelize.

    To be lazy and NOT send in your product registration card!

    I mean, seriously. How else would they know who bought it and how to get a name from that serial number? I guess maybe if the store kept your credit card info on file or something and associated it with the serial number, but how often would that happen?

    Lesson learned, if you want to print hundreds of forged checks or counterfeit bills, pay for the printer in cash!



    Actually, if you're going to do anything illegal, cash is king. Just print some up and, well, ....

    Anyway, police officer friend of mine once who said that if you're going to do something illegal, do it big, do it once and don't tell anybody.

My house was hit by lightning last year and the city of Southlake was kind enough to send a real fire engine, not just email a JPG or something.
