  1. Re:Reliability on 96 Processors Under Your Desktop · · Score: 1


    And remember that in a data center, it's not "time is money," it's "space is money."


    Actually, that's a fallacy. Space doesn't cost, kW cost! This is especially true for clusters.

    I can picture my "little" engineering company buying three or four of these boxes for CFD modeling alone... and we really aren't the target market!

  6. Re:Have you been in a reseller's shop? on Memo to Apple: Respect Your Resellers · · Score: 3, Insightful

    I agree with you completely... but the key is that most have blown it, not all. Some of the shops (god only knows where!) did do a good job, and did a lot to promote Apple through the years.

    It could very well be that the margins drove the quality of the resellers down, which is a shame, but... not entirely Apple's fault.

    FWIW, I buy most of my Apple stuff at the worst place of all... CompUSA... when the Apple store is two blocks away. As much as I hate the ignorance of their employees, I was never the kind of person to really like a boutique shop... for actually spending money.

    But, you can't blame Apple... It's an image thing...

  7. Gigabit Ethernet??? on Army Contractor To Build A 1566 Xserve Cluster · · Score: 1

    How will they be able to get the performance with gig-E instead of the Infiniband? I appreciate that it might work fine for the application (CFD analysis), but I wouldn't think that the benchmarking would bring it to number 2!

    Can anybody enlighten me???

  8. Re:is this the Alpine ipod ready kit in disguise? on iPod Your BMW Officially Launched · · Score: 1

    From the promo, it does sound like Alpine does a MUCH better job than BMW; the whole "5 playlists" thing is a joke, and from the picture it doesn't even look like it shows the song title!

    It amazes me that someone would really consider buying a frigging car based on this! But then again, I don't own one. Too bad they don't have adapters for bicycles...

  9. VAT on iTunes Europe Goes Live · · Score: 1

    Actually, the US doesn't have VAT, per se; we apply sales tax "at the register," so prices always exclude any tax. There are exceptions (gas, liquor, cigarettes, and other "special" items).

    The highest sales tax is about 8.75%, and the lowest is 0%, depending on state.

    IIRC, iTunes doesn't charge sales tax in the US. If it did, it would be added to the $0.99.

  12. Re:Room temp water cooling for processor #2 on New PowerMac G5s: Up to 2.5Ghz, Liquid Cooled · · Score: 1

    A fan alone will not influence the wet bulb temperature, and hence not permit the temperature to go below ambient (dry-bulb) temperature. The radiator cannot cool below dry-bulb temperature.

    If you chose to use evaporative cooling, you can get something for "nothing"*.

    *Nothing in this case is the cost of the water.

  13. Re:Is that lower CPU off? on New PowerMac G5s: Up to 2.5Ghz, Liquid Cooled · · Score: 1

    The alternative is that phase change wouldn't occur until the second processor. This would be a more ideal heat pipe design. Thus, the color could refer to temperature and not total heat.

    This would also explain why they use a variable speed fan; it would improve the performance of the system by not completing the phase change until after the second processor. The system would ideally operate at a phase change, reducing the fan energy (and noise), which would be the justification of not over-cooling the liquid form.

  14. Re:maybe they don't have a 30 year old spare on Software Upgrade Crashes UK Air Traffic Control System · · Score: 1

    Actually, as I understand it, there is a "test" system for the US FAA in NC. All changes are rolled out there first (ALL changes... down to replacing a UPS system!). The system can monitor traffic, but it is primarily a redundant system.

  15. Re:not gonna happen, the lobbies are too powerful on Do-It-Yourself VOIP Telco · · Score: 2, Insightful

    In a truly rural area, it would be harder. Most utilities co-mingle different substation feeds within a city, though. So, the challenge is to find a good solution for suburbia.

    Since the router is 23W and a 12VDC power supply, a cheap deep-cycle marine battery could be rigged up without too much trouble and provide two full days of backup. With the charger and everything, it might run an extra $120 total. This should get you well under 8 hours of downtime per year if done right, which puts you at three nines. (If you do a better job on the DC system, you might be able to get four nines.)

    With even just 10-20% of the nodes having three nines, maintaining network reliability of five nines is trivial.

    On a network level, if diversity is maintained between edge uplinks (cable, dsl, maybe even a T1 here and there) keeping those five nines shouldn't be too hard.

    The biggest challenge keeps coming back to getting the uplinks to be sufficiently redundant and unencumbered with TOS restrictions.

    Actually it's the embracing and extending that has made Microsoft a monopoly. Interoperability is important for attaining the critical mass.

  17. For me... on Device for Taking Travel Notes? · · Score: 1

    I travelled around Asia and Europe for ~2 years with a Palm and keyboard. I was able to write stories and notes, and synchronize them up whenever I had a chance, at an e-mail place. It worked ok for me; I was able to keep more detail than I would have if I transcribed things.

    As for cost, my biggest problem was that it was a Palm V, and re-charging was a pain in many places. It is some money, but in the scale of things it isn't that bad. Also, if it did die on you, a replacement is a commodity item (albeit a downgrade...).

    The only "cool" hack I had at the time was a bootable Linux CD with the required drivers. Odd how internet cafes get fussy about installing software on their machines.

  18. Re:Great Tech - But I have a problem... on Manure-Powered Generators On The Rise · · Score: 1

    The simple response is that you get paid at retail prices for your power, not generaton prices. Your total bill is generation+transmission+distribution; generation is usually only half the cost.

    PG&E is effectively paying you twice what it costs them to produce electricity.

    The utilities only benefit if the generation will offset the need to expand transmission and distribution lines to accommodate growth over time.

  19. Re:Fiber on How to Protect a Network Against Lightning? · · Score: 3, Insightful

    Fiber is the starting point. Lightning rods (ideally the dissipation kind that send a spark into the clouds) will reduce the likelihood and magnitude of any pulses, but fiber between buildings is essential.

    Once you are inside a building, there are so many paths for the lightning to take, it is unlikely that you can do anything quickly to fix it. Surge arrestors on incoming telephone, power, generator lines will help; multiple layers of protection (second set, finer grade) at the panelboards will filter out even more.

    If you don't do these things, have sacrificial components and spares. Usually that is easier...

  20. Re:Noble Effort on Free MIT Engineering Text For Download · · Score: 2, Interesting

    The editors play an important role, and losing their involvement would reduce the overall quality.

    The publishers, on the other hand do not provide the typical services that justify their share of the profit; promotion of the books is non-existant. When distribution is all they are left with, where do they add value?

    My biggest gripes with the hard-copy texts is that (a) they cost so much you have an incentive to sell them at the end of the class, and (b) they are so darn heavy that every time you move you have to consider if you really want to keep them.

    I think it would be great if a school would publish a DVD with all required texts for a "reasonable" price of $100. It can still help fund the writing efforts to a small degree, and give something tangible to students (and alums if they really made something good!).

  21. Re:Everybody? Hwah? on iPod Mini Worldwide Rollout Delayed · · Score: 1

    People were hoping it was going to be $200, not $250. Many people went ahead and bought the 15GB for $300 when the announcement was made. (Good for Apple.) Many more people said that it was only $50 more than a RAM based player... and ordered one. (Good for Apple.) Some other people went ahead and spent another $150 or $250 over the cost of the Mini to get a 20GB or 40GB ipod... because the 15GB's were out of stock. (Good for Apple.)

    The mini rounded out the product line. People's disappointment was that it was 25% more expensive than the rumor sites had touted. Reality is that it was a very well-placed product.

  22. Re:good for the telco business on Supreme Court Rules Against Community Telcos · · Score: 1

    If it is not cost-effective for a community to be served by a for-profit telco, and the lack of service puts the citizens (and businesses) at a disadvantage, why should the community NOT be able to set up their own telco?

    You need a market-maker in some locations. Once a market has been created, the for-profit entities can easily provide value-added services, or the utility can be sold off.

    The co-op approach is effective if a sufficient majority of the people understand the need, but it fails on "visionary" type things... like setting up a high-speed network ten years ago for a community.

    The thing that HAS to be avoided is the a repeat of the whole cable tv monopoly.

  23. Re:Cooling Things with Outside Air? on 'Nano-Lightning' Could Cool Computer Chips · · Score: 1

    Usually the problem is maintaining humidity with the cold, dry air. The easiest way to make it work would be to run antifreeze (if you can get enough glycol in solution!) between a heat exchanger in both places. You would want to move the water prety fast, but you would eliminate the compressor.

  25. Re:Good luck with that on Cheap Solar Cooling Solution? · · Score: 1

    Good points on the thermal storage. One thing that I would recommend is that the array be oversized by a factor of 1.5 at least. When you have a compressor, you don't want it to cycle off and on when clouds come over. A good voltage regulator can help out there.

    12,000 BTU should do a little better than 400SF in a home-- an office would require that, though.

    Net metering is the best bet, if it is available, but mixing thermal storage would give you the "greenest" solution. I would try and run chilled water through a concrete mass in the room in that spirit; if you have a radiative cooling surface you will feel cooler than the temperature itself would suggest.
