  1. Re:Riiight on Why LEDs Don't Beat CFLs Even Though They Should · · Score: 1

    FWIW I also have had to replace 4 out of about 15 CFLs in the 2-3 years I have been using them. No cost savings seen here whatsoever, plus the disposal (mercury) requires a special trip to the recycling plant.

    Some manufacturer out there (got mine at Lowes/Walmart) is selling some crap bulbs.

  2. Old tech, new name on Cognitive Radios Could Increase Wireless Spectrum · · Score: 1

    Dynamic allocation of frequencies has been around for quite some time, it's called a trunked system.

    I guess the hype here is that they're using SDR technology to do it and a few neat tricks with wifi as well. Must be about time to sell the next generation of new radios to the gov/corp worlds.

    I tend to agree with the earlier poster who said simpler is better. At least having a simpler backup system seems reasonable here for the early adopters anyway.

  3. Re:dumb people lose money, not freedom on Jail 'Greedy' Scam Victims, Says Nigerian Diplomat · · Score: 1

    Indeed, I received a brown wax-paper envelope from Nigeria in the early 90s with such a scam enclosed. It was quite a curiosity back then as I'd never recieved anything from Africa, and it also was quite a bit more literate than the email variety. I knew right away it was a scam though I didn't understand the mechanism entirely, so I briefly mused about setting up an empty "deposit only" bank account for the promised "deposit" just to see what would happen.

    I suspect that the investment in the postage made the need to be more professional more important, and thus the scam worked better, now the costs to send are low and the returns can be as well.

    Plus I suppose you're more sure to get a genuine idiot if you use crappy grammar and spelling and they still bite.

  4. Re:Summary and article are full of crap on US To Launch Military Orbital Spaceplane · · Score: 1

    Sure, it probably would be harder today to keep launches secret. But there's a good history of this sort of activity.

    The USSR had a lot of secret military vehicles and sats sent up under the guise of their civilian program, including a manned spy satellite that was equipped with "small" arms.

  6. Re:Holy crap I RTFA... on Pittsburgh Cancer Center Warns of Cell Phone Risks · · Score: 1

    Frequency (higher = more dangerous), wattage and distance are the generally accepted determining factors for safety.

    The signal strength declines on a logarithmic basis as distance from the source increases, so having the transmitter right against your skull ensures a good soaking in near ~800mhz RF but it's unlikely to do anything to the guy sitting next to you in the bus.

    Many people work around higher frequency or higher powered RF without problems, I myself operate a ham radio station and keep things well within safety limits the majority of the time, but I would never expose myself to UHF frequencies even at 1/4 watt at such a close range.

    Calculate it yourself, 800mhz 0.25 watts:

    Evidently by FCC standards there could be a problem.

    Follow the money, especially with university studies- they're almost always funded by industry these days. Sadly.

    The only ones normally wanting to fund such university studies are cellular providers and equipment manufacturers. They're only going to fund studies that are very likely to show "no conclusive result" because that gives them plenty of deniability. The more studies they can fund to get no results, the more deniability.

    Same strategy used by every other corporation.

    It would be good to get some actual cancer foundations involved (who don't have cellular execs on their boards) and fund some unbiased studies to put this to rest.

  8. Re:Well on H.R. 4279 Would Establish Federal IP Cops · · Score: 1

    American politics are pretty simple; the suits in this country believe that IP is the cornerstone of our overall societal wealth, and it is therefore a thing to be hoarded. For now those companies who benefit from this hoarding will continue to pull the strings. Expect more of the same and be surprised no longer.

  9. Re:People don't learn from history on Barack Obama Wins Democratic Nomination · · Score: 5, Insightful

    Without tax revenue, the bills from the excessive spending of the Bush administration cannot be paid . This is deferred debt. This is why tax cuts were irresponsible and not appropriate.

    Everybody agrees that we should cut spending (on things that don't benefit them directly usually), but it's my view that we should spend only money that we have. That's how I manage myself and it keeps me happy and those who deal fairly with me happy.

    Ever since the rabid warmongering of the paranoid years of Truman we've been digging this deficit hole and it's got to a point where we'll never get out, we'll just collapse one day because everybody's just too short sighted.

  10. Re:People don't learn from history on Barack Obama Wins Democratic Nomination · · Score: 4, Insightful

    Those tax cuts combined with deficit spending means you just enjoyed the theft of resources from future generations as well as the future you. That's how economies really work, there's no free lunch, just deferred debt.

    Most Americans however can't see past the upcoming quarter evidently.

    They will make an attempt to trick you into altering (often in my case) outdated info when you log in for the purpose of transferring. If you change the slightest character of the domain information you'll be stuck in a position of not being able to transfer it until the next cycle for "security purposes"

    Hopefully they will continue to abuse their monopoly so egregiously that they'll lose it in the end.

  13. Re:tasty on Professors Slam Java As "Damaging" To Students · · Score: 1

    I don't think that he is objecting to the language. Perl was my first language also since it has such low barriers to entry, but I no longer use it for anything other than quick hacks because its object model makes it less desirable to me than some other languages for larger projects. The Perl community is fantastic, and it is a very practical extraction and reporting language. Just not a language I'd want to build anything large with because my inclinations are elsewhere. Being exposed to a lot of different languages and experiences in general during the educational process is the key to getting a good background for software engineering.

  14. Re:Ham's day is over, probably on Ham Radio Operators Are Heroes In Oregon · · Score: 1

    Keep in mind that they did do a lot to still encourage CW use by having sections on HF available CW-only to Tech class licensees. That was enough to get me interested before I upgraded my ticket, and now that I have I still am interested as the majority of contests happening these days use it too. I think there are plenty of incentives to hams to learn it still. In my opinion this "carrot" approach beats the "stick" approach by far.

    So higher frequencies are actually _less_ dangerous. Quite wrong!

    As a ham radio operator I have to point out that RF radiation exposure limits are a function of frequency and time, and the higher the frequency you deal with the less time you should be exposed to it!
