  1. How about spread spectrum sonar? on Patent Filed for Underwater GPS · · Score: 1
    Sending out active sonar in a military context is pretty stupid.

    Although I have not heard of this being done, it could make a lot of sense to use spread spectrum sonar, for ranging anyway. Spread spectrum allows you to get far better signal to noise ratios meaning you can work with far lower signal power (for example, GPS receivers use this to cope with signal strengths that are below thermnal noise). This could give you active sonar without being too obvious to the enemy and without messing up the whales.

  2. This is not GPS! on Patent Filed for Underwater GPS · · Score: 4, Informative
    I didn't RTFA (that's cheating), but the summary is a crock.

    This thing is not GPS. It is sonar ranging that just happens to also includes the GPS locations of the bouys to help give a true position. Doing sonar positioning requires that you know where the bouys are and GPS provides a very good way of doing this.

  3. Hurd lacks drive and energy on How Open Source Projects Survive Poisonous People · · Score: 1
    Hurd predates Linux, but it lacks drive to get it anywhere.

    IMHO, the major difference is that Linus is primarily a doer/engineer while RMS is primarily a talker/philosopher. Linus sees GNU and GPL etc as tools to get to where he wants to be, while RMS is is more interested in the almost religious pursuit of GPL and the software just comes along for the ride.

    Witness the whole GNU/Linux naming debate: For RMS, this was a very important milestone http://www.gnu.org/gnu/gnu-linux-faq.html; Linus thought it ridiculous, but didn't burn much energy in debating it.

  4. Is this the same as the UK sun detector? on NASA's Instrument For Detecting Life On Mars · · Score: 5, Funny
    Many years ago ETI magazine has a circuit for a UK sunlight detector The output was claimed to go to 5 volts if sunshine was likely in the UK. If you looked at the circuit carefully, it was just a dead short that could only ever produce 0 volts.

    This device was also claimed to work as a Sahara rain detector.

    Perhaps NASA could use one as a Life On Mars detector too.

  5. gdb remote is useful on Debugging the FreeBSD Kernel Transparently · · Score: 2, Interesting
    This is a very cool feature in gdb that is very commonly used to debug various embedded systems etc. Sometimes gdb remote uses a serial port or tcp from the host to a stub running in the target (as is the case with Redboot).

    Also, gdb remote is often used to talk to a server that mimics a gdb remote stub and then turns the commands into some other connection into the target (eg. a JTAG debugger).

    All up, this makes debugging embedded systems a lot simpler than it would otherwise be.

  6. Reactos Alpha = Windows Beta? on ReactOS 0.3.1 Released · · Score: 1

    It would be interesting to compare Reactos' interpretation of Alpha vs Microsoft's. What's the BSOD rate?

  7. Telecommuting is still better on Google's Best Perk — Transport · · Score: 2, Interesting
    The only hassle with Google is that you need to show up to make use of all their other perks.

    With a broadband connection you can work from home just as easily as from a cube. I've been doing that for years as an employee. As a moonlighting consultant I often work for people I have never seen in countries I have never been to.

  8. It's part of a reciprocal agreement on New Mexico Might Declare Pluto a Planet · · Score: 2, Funny

    Pluto is recognising New Mexico as a country.

  9. Google, the porn portal on Wikipedia's Search Engine Plan · · Score: 1
    Since porn etc searches make up a considerable % of Google's searches it probably makes Google the largest porn portal site by far. "Feeling Lucky isn't called that for nothing!

    Editable searching could be quite useful. From the search criteria you can guess the type of porn the person wants and direct them accordingly. Afer all they might type in "lawn mower" but you really know that deep down they want some shaved chick porn.

  11. Re:It works fine! on Prescription Meds For Vista Sleep Disorder · · Score: 1
    True. But it is hard to believe that all the talent in MS could spend $5bn and come up with so little. It must be hard for the shareholders to think that Vista is a $5bn improvement to XP.

    The biggest sale has to be to the shareholders not the customers.

    Now that could be useful!

  13. It works fine! on Prescription Meds For Vista Sleep Disorder · · Score: 1
    From MS's point of view anyway. Just remember what MS is trying to achieve. They are not after perfection, they are just after having something that is good enough to make a sale. It does not have to work 100%.

    MS had promised Vista in 2006 and many companies had put Vista buying in their 2006 budgets. Thus, MS had to ship something for these companies to buy in 2006. From the perspective of the customer companies, keeping the budget on track is far more of a deal than a few sleep problems. MS just had to ship something, anything, and it would be bought.

    And sleep problems etc? Well you can just blame them on "driver problems" and make the hardware vendors take the heat.

  14. It's no big deal on Alternatives To SF.net's CompileFarm? · · Score: 2, Informative
    Compiling is only half the fun. The compile farm cannot test most of the applications. Thus the compile farm only does half the job needed to release a package.

    Most projects are staffed by people using multiple platforms anyway and anyone coming along with a requirement to support some odd-ball OS might just get pulled in to do compiles and tests. For example, the SF project I work on is mainly staffed by Linux people with a few Windows and this project does not use the compile farm. Those using OSX just need to recompile and it works for them.

  15. Lefty != Libertarian on Political Leaning and Free Software · · Score: 3, Interesting

    Left vs Right is orthogonal from Libertarianism. Some of the most libertarian organisations are the most right wing. eg. the survivalists in USA.

  16. How do you make it wait? on Anti-Matter's Potential in Treating Cancer · · Score: 1

    So how do you wait for the antimatter "know" what to anti? Is it clever enough to eat up a tumor and not eat up the nurse that goes to fetch it?

  17. Beat them up one at a time on Vonage Loses VoIP Case With Verizon · · Score: 1
    You beat them up one at a time, starting with the one that you think you'll beat easiest and that are likely to give some returns. Once you've beaten one then there is a bit of precedence which makes your club bigger and their skulls thinner.

    You also don't beat up ones that the jury (if there is one, I didn't RTFA) are most likely to be using personally or see as "The Good Guys". ie. Don't beat up on Skype. There are a lot of people who use Skype personally and a jury of those people would likely feel that they'd personally lose out if Skype got damaged. Rather beat up on someone else.

    Then there's also the concern with legal fees etc. If you take them all on at the same time, you invest a lot in legal expenses. You're exposing a lot of cash. Rather expose a smaller amount of cash at a time.

  21. Re:Who would Gates attack? on 'Gates for President' Group Gives Up · · Score: 2, Interesting
    Most people do get this point. Well non-Americans anyway, and I beleive even Americans get this point since it underpins the change in congress. However many, particuilarly leaders of other countries, have been unwilling to say so openly. Love-me-love-my-war has been an important part of doing business with the USA and has been used extensively as a bargaining chip with trade agreements etc. Bush was very clever to mix in terrorism because he's able to put himslef on the good-guy side and everyone else on the bad-guy side.

    Now there's a Democratic government those countries that have been holding their tongues have started to speak more freely.

    Leaders love wars for two main reasons: Firstly there's a patriotic "We've got to pull together" feeling that fosters cooperation with authority and makes people put up with situations that they would otherwise object to. If it was not for the war, Bush would not have wangled his second term. Secondly wars get presidents in history books. Big ego-rub.

  22. Did the math teachers complain? on Higher Pay for Math and Science Teachers · · Score: 1
    Most likely it was mainly the unqualified, or those with history - and other low-dollar skills - that were complaining

    Sure, history etc are important, but they have no significant earning potential outside of teaching. It's a buyer's market. Qualified scientists have far better prospects.

    With any belief system, there are always some axioms - weasle words you just have to accept otherwise the system, and thus any framework for discussion/debate, falls down.

    God made the Universe: Ok then, so where did God come from? Well He's always been there... So if God has always been there why can't the Universe have always been there? Nope, God existed before everything else.

    The Universe was created by the Big Bang: OK what was there before the Big Bang (ie. where did all that energy come from)? You can't ask that, because the concept of time is meaningless before the Big Bang.

  25. Who would Gates attack? on 'Gates for President' Group Gives Up · · Score: 2, Funny
    The whole Iraqi war has nothing to do with terrorism. If is far easier to find a link between Bush's interests in the oil industry and destabilizing oil production to boost the income from Bush's oil buddies. In other words, like wars of long ago, this war is more about the leader's [ersonal interests than anything else.

    Would Gates declare war on Linux-loving nations?
