    Sorry, we elected the governor and attorney general last year, and they are both on 4 year terms.

    Oh, and the democratic challenger to the republican minority leader (was majority until they lost the senate) is utterly pathetic. I didn't vote for Lunsford in the primary but, ugh... he has to be better than McConnell.. same went the thinking about Beshear vs Fletcher. :/

    An executive MBA program is a part time program (evening usually) for people that already have some management experience. A standard MBA program is one where students attend full time during the day, and students can usually be accepted straight out of undergrad. An executive MBA is much more expensive as its expected that your company is paying for you to be there as a part of "executive" or whatever training.

    You do realize that that has to do with incompatibilities with a SATA->PATA bus and not TPM, right? The BIOS warns when there is a firmware on the hard drive that is "incompatible" with the chipset.

    I assume that you're talking about this issue. You could also be complaining about your BIOS reporting that your hard drive doesn't support active protect. Neither of these issues has a thing to do with TPM.

    What is true is that on average, men and women have different interests.

    The "average" man or woman wants to be a doctor, lawyer or business executive. In the case of doctors and lawyers, women are now more successful at getting those degrees than men, and it would not surprise me if its true for business degrees too (it wasn't mentioned in the article).

    Not many people, male or female want to become a scientist or engineer. This is the overall problem, and is especially bad when looking just at female numbers...

  18. Re:FUD and not so FUD on Embedded Microchips In Virtually Everything · · Score: 1

    So, how are you going to integrate this package into a electronic product code for say, a T-shirt or on a soup can? As distance increases you start talking about needing to store larger amounts of energy before you can send it back, which means a higher capacitance. You'll quickly get to electrolytic can packages. The fear in the article is that you'll be tracked based on these items, which means that the rfid has to be small enough to be unobtrusively left in many items on your person. The type of RFIDs that are best for these uses are tiny, flexible, and thus are not capable of "replying" with much energy, hence the very limited ranges.

    Wouldn't you burn out the RFID chip before you could read at more than a few feet? The wires used for the passive antennas in cheap RFIDs cannot take much current.

  21. Re:Physics on Cooling Challenges an Issue In Rackspace Outage · · Score: 2

    Just FYI - a watt is defined as 'the power developed in a circuit by a current of one ampere flowing through a potential difference of one volt." see http://www.siliconvalleypower.com/info/?doc=glossary/, i.e. 1W = 1VA. The dirty little secret about power calculations is that there is another factor thrown in, typically about 0.65, called the 'power factor' that UPS and power supply manufacturers use to lower the overall wattage. That's why you always use VA (rather than the reported wattage) because in a pinch you can always measure both voltage and amperage(under load).


    If you don't want to learn anything about AC power, please don't call it a "dirty little secret". Wikipedia for example would be a good place to start.

    I'll summarize for you though:
    Real Power (P) - has units of W. This is the amount of power dissipated into the "real" (resistive) part of a complex load.
    Reactive Power (Q) - has units of VAR (volt-amp reactive). This is the amount of consumed by the reactive (capacitive/inductive) part of a complex load.
    Apparent power (|S|, S = P+jQ) - has units of VA (volt-amp). If you plot P and Q on the complex axis, you this is what completes the triangle.
    Power factor - ratio between real and apparent power. (P/|S|) For purely resistive loads, this is 1. For purely reactive loads, this is 0.

    A UPS is basically just a battery with a bit of supporting circuitry. The battery can only deliver a certain amount of energy per time (some type of power). If this energy is all going to a resistive load, then yes, it would be what you think it is, Watts. This is also the apparent power the UPS can deliver in VA (P=|S|, PF=1). If the load is purely reactive, the apparent power will remain the same in VA, however the real power will be 0. For this reason, UPSs are rated in VA. They can make no guarantee about the amount of real power (W) they can deliver, as it will depend on the load.

    Hopefully that makes sense and I haven't confused things further. (power EEs may have something to add/correct, I'm more of an electronics one going off memory)

  23. Re:tight ships have less to gain on Wal-Mart's Faltering RFID Initiative · · Score: 1

    What does determining where your stuff is have to do with RFIDs? The type that you're likely to see in warehouses on every single product (what you're describing) are passive and can be read at about 1-2 feet realistically. This is similar to using a barcode reader. I would assume that in a good warehouse, you'd have something like your typical shipping labels on all the pallets/packages/whatever and can read off its data as its being sorted. That is basically all you'll get out of RFID as well. Putting an RFID on a box is nothing at all like putting a GPS transmitter that will always tell you where it is - its like putting a barcode on a box that can be read from a little further away. I would imagine that this helps a lot with processing stuff in a warehouse as you wouldn't have to manipulate the packages so much. (ie, look for the barcode)

    Now, having an RFID on every distinct product would be nice. You could in theory walk your cart through a large reader and immediately ring up everything you had in your cart. As I recall, IBM had a commercial featuring a technology like this years ago.
