  1. How do we know it is a man? on Meg Whitman Campaign Shows How Not To Use Twitter · · Score: 1

    We have no proof that the player is a man. The player could be female. It is sexist to think that someone with a couple of masculine features is necessarily a man. You find the player unattractive? Perhaps, by your cultural standards.

  2. Flag semaphore and interference cancellation on DARPA Wants Extreme Wireless Interference Buster · · Score: 2, Informative

    Flag semaphore remains highly resistant to electromagnetic interference. http://en.wikipedia.org/wiki/Flag_semaphore There is more to be done with interference cancellation techniques using active multiple-antenna systems, that can place a null toward the source of interference.

  3. Get help from pros on Ideas For a Great Control Room? · · Score: 5, Funny

    I would contract with a design/build firm that specializes in these facilities. You don't want to do this by the seat of your pants relying on Slashdot advice.

  4. Headline FAIL on Layoff Anxiety Is Top Risk To Space Shuttle · · Score: 1

    As I read the article, layoff anxiety is a risk but not a top risk. It was addressed, in part, by worker pride wanting to stick with the mission, and a bonus scheme that encourages workers to stick to the end. On the other hand . . . "Among the chief technical risks in the latest review, presented to program managers this summer: -- Catastrophic strikes by space debris; -- Aging propellant pressurization tanks that might explode; -- Foam or ice breaking free from the shuttle's external tank and doing critical damage to heat-shield components." Those would be your top risks at the moment.

  5. Re:Good grief on Solving a Wiring Mess? · · Score: 5, Insightful

    I think you get a qualified electrician to look at this and fix it. If the budget does not permit this, change the budget or consider the business failed. Next go-around, get better due-diligence review of the facilities. We techies can do some power if we are know what we are doing, but this sounds like it is out of our league. One may well have to turn off service power at the pole (or other building entrance) to redo this. Also, you are talking big conductors here, which our techie-tools can't handle. Leaving it alone is bad because there is already evidence of loose connections and grounding problems that will cause your 220 volts to vary over a wide range intermittently, eventually damaging the equipment, and possibly causing electric shock to employees touching poorly-grounded cabinets.

  6. The FCC can't move mountains (or hills) on Wireless Growth & Wireless Interference · · Score: 2, Informative

    Interference is a relatively new part of this problem. For decades, public safety has had "holes" in coverage caused by hilly terrain blocking the signals. Same thing happens with cell phones, but the cell phone companies can afford many more transmitter sites to fill in the gaps. Put another way, public safety coverage will never be as good as cell phone coverage, for reasons that have nothing to do with interference. Reallocate the spectrum all you want -- it won't cure this problem, but it could help with the newer interference issue. What might also help is independent third-party review of public safety radio system designs that are originally drawn up by the same companies that are selling radio systems to the public safety agencies. Some agencies have no idea of what they ordered or what performance to expect or, moreover, the tradeoffs between cost and performance.
