    They were once one of the biggest direct mail PC sellers. They had multi-page ads in Computer Shopper and PC Magazine. They later started having their own monthly mini-catalogs. Today they just seem like a joke compared to Newegg.

    TPM itself is just a secure key store, you would need a BIOS and signature checking agent to ensure nothing else was involved in the process. I don't believe there is currently anything like that available for the PC platform. It's what all the doom sayers from the Linux camp said TPM would bring but I don't believe it's here yet. The sophistication of attack needed to compromise a TPM protected system is very high though because you can set a BIOS password and have the system clear the TPM keystore when the BIOS is cleared so the only real means of attack is direct memory manipulation through a DMA controller.

    The only way to inject code during boot if you are using bitlocker would be to use a DMA controller to do the injection. Firewire ports are one of the few devices commonly found in a PC with a DMA controller that can be used in this manner.

  5. Re:Infiniband: a better technology in the datacent on The Road To Terabit Ethernet · · Score: 1

    Infiniband cheaper than Ethernet, you MUST be off your rocker. HP dual port 10Gbit Ethernet card costs $700, DDR Infiniband card is $1200. Sure it's cheaper to buy one Infiniband card than two Ethernet cards but few applications need more than two 10Gbit ports today. Also 10Gbit Ethernet is rapidly becoming comoditized in switches, Infiniband due to small market penetration basically never becomes commoditized.

    It's not like high speed ethernet cables handle any of that well at all! As soon as you deform a Cat6A cable it will no longer be able to handle 10Gbit.

    Alien cross talk can be a problem for real world applications of gigabit ethernet, you won't notice them in your switch logs but you may be seeing all sorts of silent problems at the physical layer that retard your maximum speed. Cat6 installations solve the AX problem. If most of your users are not power users than it can be cheaper to just run a STP Cat6 drop to the individual power users and leave everyone else on cat5/5e. That's unfortunately what we are doing with our new building as today everyone but our marketing department is fine working through their 100Mb phone loopback devices and the company doesn't want to spring for the better physical plant. It's easy to show that in the long haul it's cheaper to do it right but today no one wants to hear it. It's funny because it's one of the only areas this company has skimped in the three years I've been here.

    Oracle was already getting into the hardware game but reselling HP kit, now they have their own in-house products to use so they have complete control over how the storage engine is built from top to bottom, might lead to so very interesting, very optimized clusters for large scale database work.

  11. Re:counter offer? on Ballmer, IBM Surprised By Oracle-Sun Deal · · Score: 1

    I'm sure there was a nasty poison pill in the offer where Sun would have to make Oracle whole if the offer fell through. I've heard of clauses as much as 20% of the acquired companies value so the deal has to be seriously low bid for it to be worth someone elses time to meddle with the deal at that point.

    Almost all wall units have thermostats built in and quite a few of them have programmable thermostats. Personally if I didn't have whole house I would spring the extra bucks for a programmable wall unit since the payoff there is probably weeks instead of months.

    I'm going from talking to my friends who work in tech and maintenance in both fields. Cold and sand are both pretty rough on even stuff that's designed for milspec (extended range) operation. There's a reason that milspec exists, see the M16A1 for a perfect example of how not properly designing a system for field use can cause serious loss of life.

    The touch has operating specs of 32-95F, Afghanistan gets MUCH colder than that and Iraq gets MUCH hotter than that. Put it in a water and sand proof sleeve and the high end of that range probably drops. Also the touch has a ceiling of 10K feet, there are tons of places higher than that in Afghanistan (though I'm not sure what other than the accelerometer might be affected by altitude).

  15. Re:Iraq and Motorola Talkabouts on US Military Issuing iPod Touches To Soldiers · · Score: 1

    Sadly true, but more than anything shouldn't that have been a wakeup call that the military needs to spend more time focusing on the soldier in the field and perhaps a bit less on $150M a shot Globalhawks or $1B+ B2's? Perhaps the focus on the soldier that Gates espouses will actually come to fruition before the end of this series of conflicts. Perhaps it's because only three secretaries of defense (Perry, Weinberger, Richardson) have seen combat from the ground level vs big ships or airplanes or map pin pushing that there's been such an emphasis on the big battle systems at the detriment of the men in the field. I think it's so despicable that we spend almost as much as the rest of the world combined on defense but can't seem to get the tools our soldiers need in their hands.

    Wind farms and geothermal heat pumps are definitely net energy producers over their design life. They might not be as cheap as chopping off the top of a mountain and using dead dino plants to make electricity but they are most assuredly net energy producers.

    What the heck do you think the AC in HVAC stand for? Plus there are programmable wall units, in fact it's even more important with wall units since the lower efficiency means the power savings are greater (less than 10 SEER vs 13+ for whole house units).

    The problem is the HAVE the ruggedized,secure general purpose computer system, they just chose not to fund it. It's called Land Warrior and it runs Linux on XScale so should be simple to design for. Building Glabal Hawks for $125M and then skimping on a couple thousand per field user is just the kind of crap the military loves to do to the soldier in the field.

    How disposable is the device if you are in the field relying on it to bring back realtime intelligence from a drone? The problem is that you have a very expensive information collection system built to battle standards and tactics built around those systems and then you cheap out on the part that makes the information actually usable. Like normal this is the brass crapping on the guy in the field after spending trillions of dollars on the toys. Who's brilliant idea was it to build the modern information centric battle systems without designing a milspec general purpose computer for the field soldiers?!? Oh yeah they canceled that in 2007 after completely screwing up the process from design to implementation (land warrior).

    Not. Unless they are getting milspec units I wonder how many lives are being put in danger by using consumer products in such varied environments. The mountains of Afghanistan in winter and the deserts of Iraq are probably both well outside of the rated range of these devices. Not only that but what happens when they get a little wet? I think the average joe shmoe probably treats his electronics a bit better than your average grunt. I personally love the idea of using something like this to control things (my wife has a sewing machine that uses a gameboy color for a controller), I'm just not soldiers are the best target audience for such efforts.

    Most internal combustion engines average 18-20% thermal efficiency (that is only about 18-20% of produced BTU's are available mechanically). System efficiency is even lower due to friction in all the components between the engine and where work is done.
