    The Palm desktop application sucks. You can work around some of the issues you mentioned though. Moving text files is pretty straightforward if you just copy and past the content. There are file size limitations though. A better way is to write to your SD card directly, and use (on the palm) an application (like FileZ or UniCMD) to access it.

  4. Re:This is a crock of shit on An Update on Patrick Volkerding · · Score: 1

    I know nothing of rife machines but I'm afraid that you are mistaken. A good example of "hetrodyning" is a "superhetrodyne" receiver. (Pretty much every radio receiver made these days works this way.) An internal "local" oscillator is mixed (in a mixer) with the amplified input frequency (the one of interest) to prodice an intermediate frequency (IF). Whenever you mix two frequencies you get both sum and difference. The IF is filtered to remove the sum (image) and keep the difference. (Sometimes the receiver is designed to keep the sum and lose the difference.)

    As light is just electromagnetic radiation, the same principles apply. You can beat (mix) two different light sources together and produce both sum and difference. This doesn't usually work very well unless the light sources are coherent (lasers).

  5. One thing China desperately needs... on China's Superior Technologies · · Score: 1

    Is CLEAN RESTROOMS. I spent last month in Dalian (north eastern "bit port" city) and was impressed by all the new technology (I was there 3 years ago), but disgusted by the same lack of basic hygene that is common throughout the country.

    I swear that the Chinese as a race must have diminished olfactory receptors. (The average Chinese proboscis is indeed smaller than the average European one). There is sewage in the streets and filth everywhere you go.

    Another thing the Chinese are renowned for is POLLUTION. They haven't seem to have yet figured out that they have to live on the planet they are rapidly destroying. There are no environmental restrictions on business. Enforcement of what little rules they have is selective and corrupt.

    Another thing China seriously lacks is SAFETY. They haven't figured this out yet either. Nobody wears seat belts. Anything with a motor is allowed on the roads. Pedestrians had better look both ways and run out of the way because they have no rights whatsoever. Construction sites leave dangerous holes in the middle of the sidewalk with no warning barrier. You really need to keep on your toes at all times.

    My last rant is about the Chinese cultural aversion to MAKING AN ORDERLY LINE. There's no such thing as a line in China, it's everyone for themselves. It shows up everwhere from customers at a street vendor's cart to the downtown automobile traffic. There is no logic to the rules of the road, it's a constant game of "chicken".

  6. Linux software RAID is not ready for prime time on Experiences w/ Software RAID 5 Under Linux? · · Score: 1

    I've been running a RAID server with Linux for about 6 years. I ran software RAID-5 for the first 2 years or so and there were several things that came up. There were a few times when the system crashed and the array was out of sync (not all the drives had the same sequence number for the last write). It required some manual troubleshooting and head scratching. There was also the issue of strangeness when the hardware failed. A few times I had a drive go bad in such a way that it was not visible to the BIOS or boot scripts. In those cases the software RAID drivers got confused. They would not allow the operation of the array with a missing disk. I had to install a drive (any drive) even to just use the array in a non-redundant mode. Also, if you're going to do software RAID with IDE drives, absolutely DO NOT use more than one drive per controller channel. It may work for a short time but you WILL have problems.

    After a few years of problems like this, I never had a warm feeling about the reliability of the system so I installed a 3ware hardware RAID controller (IDE). After another few years, I upgraded to another one (SATA). I've been most impressed with 3ware's product performance, reliability, and support.. I highly recommend them.

  10. Re:Reverse firewalls? on Reverse Firewalls As An Anti-Spam Tool · · Score: 1

    The rate limiting idea is good - but I think the spammers have already developed and deployed a countermeasure to it. The latest trend of having a large, distributed pool of spam bots gets past this safeguard. Each node in the pool can send low-volume spam and still deliver the spammers message very effectively. "There's strength in numbers."

    Either way, I don't like the idea of ISP's unilateraly deciding to change the terms of service after service has commenced. I'm in the very small minority of people who run their own mail exchanger.

    30 years is nuts. We don't even know if LCD or TFT displays will last that long since they haven't been around even half that time.

    I think once they can produce OLED cells that last more than about 5 years on average, you'll see them go mainstream. Anything less than that could end up costing the manufacturer big in terms of warranty obligations.

  13. This is now a common trend on Bypassing Intel's Overclock Limit Reveals DDR2-667 · · Score: 1

    For example: An Agilent 16900 logic analyzer comes standard with a 400MHz/1MB trace buffer. If you want a 550MHz/32MB trace buffer, you pay them some money and they provide you with a software key to "unlock" the feature.

    Do you think they lost money when they sold you the base unit? No, it's pure profit to them and they actually save lots of money by making just one type of analyzer and not dealing with any field installable hardware upgrades.

    Somehow it seems unethical to me - since I've already paid for the faster and deeper memory and have to pay again just to be able to use it.

  15. Reconsider some of your statements on Bulk Data Storage For The Common Man? · · Score: 1

    If your data is valuable to you, you should seriously consider using RAID. The first drive failure you have (and you will have many) will cost you more in lost data, down-time, and labor than a 3ware RAID controller would have cost. I've used both their IDE and SATA controllers and they're great. I also went through 1.5 TB worth of 250GB SATA drives in about 18 months due to failures. I'm glad I selected the WD drives with their 3 year warranty.

    For off-line data storage, consider using large hard drives and a hot-swap bay. There's nothing cheaper, faster, or of higher density.

  16. The Real Problem on Flaw in Florida E-Voting Machines · · Score: 1

    "Writing a voting system that does this is stupendously trivial as far as the code goes. Which leaves me only baffled as to why there appear to be so many bugs with these voting machines to begin with."

    You're getting close to the real problem here. Software development these days is different. Project managers want to reduce risk so they look for "COTS" (commercial off-the-shelf) products which can be integrated to meet the system requirements. Unfortunately Microsoft is one of the COTS vendors they everyone looks at. Pretty much all of these e-voting systems are based on Microsoft operating systems and database applications. Why anyone would use Microsoft software in such "mission critical" applications is beyond me, but people do.

    I agree that some simple embedded code could be written and certified to meet all the requirements (including an encrypted "voter receipt") without much effort. Such a system would be much easier to certify.

    Speaking of certification, how could any certification body approve of Microsoft operating systems and applications for such a system? The required reliability is just not there. The chance of data loss is just too high.

    They seem to have forgotten the simple fact that altitude matters when it comes to antennas. If you want to increase the line-of-sight range of the antenna, it needs to be higher so it will be above the horizon at greater distances.

  20. Re:Oh Great on New Material for More Efficient Solar Cells · · Score: 3, Interesting

    I used 14 80W Sharp polycrystaline panels connected to a Trace 1500W inverter. I've got 3 85AH Costco deep cycel batteries tied through a 60A trace charge controller. I did the installation and wiring, and also designed and built the monitor and control system. I put a D.C. (switching) supply in the system to supplement the cells when the battery voltage falls below 80%. You see, this is a "Solar UPS" so the batteries always stay mostly charged. When the cells produce less than a few amps of current, the computer activates the A.C. bypass so the inverter and switching supply inefficiencies aren't wasting power. If the A.C. ever fails, the inverter takes over within a few cycles (as a UPS would).

    The monitor and control system samples all the voltages and currents 10 times per second. It averages the result and stores everything to a log once per second. The web charts and real-time status come from the log.

    A cron job tells me the total power generated each month. The system doesn't run the house, it just runs the server, network, and phones (ISDN & VoIP).

    Right now the solar plant is generating about 20% of the total power used here. It lowers the bill by more than that due to the "over baseline" electrical rate accounting system. I've computed that it will pay for itself in 12-15 years.

    I purchased nearly everything from eBay so I got a good deal. The cells have a 20 year guaranty.

    Since it's not a "grid tie" system (I don't feed any power back), it's not elegible for any subsidy from the power company. Fortunately I was able to deduct 20% of the cost from my state taxes last year. The state (California) does not require the system to be "grid tied".

    I hope that answers all of your questions.
