  1. This is What Slashdot Should Be on Dark Matter Exists · · Score: 4, Insightful

    Did anyone else notice the amazing quality of TFA? I actually understand more about dark matter from that article than from anything else I have read on the subject to date. This makes me less grumpy about all the money I felt was "wasted" on telescopes vs. planetary exploration.

  2. Re:Isn't here more to it than 4x speed increase? on Nanowires Four Times Faster Than Silicon · · Score: 4, Informative

    Your first paragraph seems right on, but the second doesn't seem to make sense. The length of the traces have little to do with speed, it is the actual switching speed of the transistor from off to on that causes the delay. Nano wires and transistors may switch faster, but the additional 10x improvement may come from heat/density savings, not the signal path length.

  3. Re:History to put this Sun/Apple rumor to rest on Apple Making a Spreadsheet? · · Score: 1
    I'd mod you up but I would rather reply and ask for another to mod you up (please do).

    Thank you for providing a decent comment backed up with links to sources.

    Very interesting take on the subject and I agree with the outcome of your post. As I deal with a much smaller scale engineering I agree with your "talking out his ass" theory as it explains 90% of the last minute rushes I end up being forced into, as well as 99% of annoyed/dissatisfied clients.

    Keep up the sound reasoning backed up by proof, it makes slashdot better.

    Thanks for using the best sig ever.

    FF3 is the best of the whole FF series.

    I was looking forward to FF7 for the PS1 and was so disapointed (sp?) by it I have not played another FF game since.

    The only other game i respect is return to castle wolfenstein Enemy Territory, and open source online 3d shooter that takes more skill than any other game i have ever played.

  6. Re:Power BILL on Hiper Type-R Modular Blue Line 580W PSU Review · · Score: 1
    remember introductory chemistry/physics?

    change your 580W to .58KW and things start to look better (you are multiplying by KW/Hr?). There are other problems, but I really don't care enough to correct your low level math mistakes.

  7. Re:Do you know what an FPGA is? on 3D Raytracing Chip Shown at CeBIT · · Score: 1
    Absolutely right.

    wait, i have nothing to add.

    ohhh, ok, i remember. Don't think the performance is from the FPGA. It is from having all the algorithms done in hardware (transistors, heh). FPGAs are the perfect prototype board for stuff like this (as mentioned above).

    I seriously doubt they are using the FPGA's dynamic abilities.

    for example, MP3 decoding takes a decent DSP a dedicated 30ish MHz to perform. Or you could go buy an ASIC from ST microelectronis for $7 that will do it all day with almost no intervention.

  8. Re:FINALLY on 3D Raytracing Chip Shown at CeBIT · · Score: 1
    You are right in your thinking, but it is quite tough to achieve.

    There are a lot of hardware issues, such as pin assignment, that are tough to make work with every foreseeable process.

    I have worked with high end FPGAs and also high end DSPs (fancy word for fast multiplying processor).

    Without wasting a lot of time on a post to an older article, it should be done this way, but the labor ot write the software is prohibitive.

    idea: try to get all those fanatical opensource coders on the bandwagon.

    A lot of examples od MP3 decoding on FPGAs are available.

  9. Re:I disagree wholeheartedly. on Debian Release Mgr. Proposes Dropping Some Archs · · Score: 1
    I agree with you

    I run Debian the same as you, and it sure does not feel out of date.

    Thanks for taking the time to word a decent response to what i seem to hear every day.

    Maybe they need to just change their naming conventions on the releases. I was scared to use something labeled as testing, but found it works much better than anything else I've tried in the past

  10. Re:802.15.4 Protocol on Coming Soon: ZigBee Control by PDA · · Score: 1
    Ahh the problem is that the high frequency crystals are a little bit expensive, causing the price to be a bit higher.

    first of all, the new chips are fully functional devices, capable of routing messages. Check it out at:

    www.chipcon.com Or: search mouser.com for CC2500

    I am surely taling of a router node, that is why this new standard was developed.

    Also, here is evidence to show that you are again totally wrong.

    This is an article on the different naming conventions in the 802.15 standard.

  12. 802.15.4 Protocol on Coming Soon: ZigBee Control by PDA · · Score: 5, Informative
    As for saying the ZigBee is for static networks: that is 100% wrong.

    ZigBee's main purpose is to create self-assembling, autonomous networks.

    This means that well written firmware will enable a tech with no education to just replace nodes if something goes wrong, versus having to understand anything about networking.

    My job is in the development of ZigBee networks and I have worked with these devices for about a year now.

    The main purpose of the ZigBee standard is to develop low-cost deivces that operate, assemble, and route messages with no human intervention. The latest chips cost less than two dollars, meaning a whole node can be designed for much less than $10.

    RTFA, heh. The Entertainment Software Association said the Dec. 1 raids at three Pandora's Cube stores in Maryland and Virginia were a joint effort of the U.S. Department of Justice's computer crimes unit, the U.S. Attorney's Office for Maryland and the Bureau of Immigration and Customs Enforcement.

    There is nothing wrong with this, in my opinion. I feel that this is the first case of authorities doing a service to the country in a copyright infringement case

    1 Simple point it seems everyone is missing...

    The plasitc layer is to prevent " collaring " a person in an accident. (i.e. head goes through, collar & shoulders don't)

    This is a very bad thing, many decapitations.

    That is why there is a layer of plastic, to keep your head attached to your shoulders.

    I know we are all sick of this discussion by now, wish I could have put this in earlier.

  16. Re:What is the best way to increase security? on High-Tech Crimes Revealed · · Score: 2, Informative
    Absolutely not. Every single "hacker" I have seen is pretty much just running scripts they found elsewhere.

    I was in an IRC channel one night, and some of the kids couldn't even figure out how to compile the code they had using Visual Studio.

    The only problem is that most of these kids had no fear in commiting any crime, and it appears to me that they make up the majority of computer criminals.

    So, preparing to be attacked by common methods is probably the best defense.

  17. Re:And? on Water Cooling With A Car Radiator · · Score: 1
    I couldn't agree more. I machined a radiator out of a solid block of aluminum, attached a thermoelectric cooler, and was able to have chip temperatures around -20 degrees.

    And I didn't even think that was /. worthy.

    Not only does this appear to greatly help tourism by drawing children (and their parents) to sites that may have been dying from a worldwide slump in tourism.

    My first thought when reading the article was "they are going to make great interactive video games with this".

    Good job posting this in the games section.
  19. Re:MP3, but improve the quality on An Overview Of Present, Future of Music Technology · · Score: 0
    The MP3Pro is actually a great technology. I realized my terrible RCA player supported it after reading the print IEEE article a few days ago.

    At 64kbit/s, MP3pro files "sound" better than a 128 MP3. It is a great improvement, as now my tiny 64 Megabytes is the equivalent of a measley 128 Megabytes. check out the MP3pro technology at: http://mp3prozone.com/

  20. DRM for Everyone! (or am I paranoid?) on An Overview Of Present, Future of Music Technology · · Score: 5, Informative
    While the IEEE tries to be impartial on DRM issues, I have seen an increase in DRM on every new storage medium in the last year. I am a member of IEEE and I was so displeased with the DRM of my last MP3 player (the RCA one in the article, actually) that I built one that has no DRM and a better user interface (I'll post it soon)

    Anyways, look out for many of the DRM features lying around to be activated in the near future. The biggest concern will be in memory cards, as most of them have built in features to erase the file after a certain number of plays.

    Also in the near future: DVD players having their playing rights revoked (a code on the disc only allows keys stored on approved players to access the content. Both of these are not "coming-up" technologies, they exist at this very moment in hardware, it is just a matter of time before manufacturers activate them.
