    Cool. What do you use? What does it run on (hardware/os)? Like it? Used it long? Any other helpful hints?

    I use a Simple Share by Simple Tech. They have several flavors from 160, 250, & 400 Gig. If you look online you can find info on changing the HD to something you like. It can also use external USB drives in addition to the internal one.

    Cavit.. Watch the firmware version. They are flashable, but the newer versions of firmware have dropped the partitioning and encrypted partition features. Check online for the features you want and flash the drive to the version you wish. Remember, the new versions have dropped the encrypted partition support.

    Another note. Avoid the 160 Gig model. It has a 1 year warranty while the others have a 3 year warranty. If it is not in a secure location, they have a place for a laptop lock.

    I love the partition that becomes a brick if the unit is "borrowed". I keep my banking, tax, password lists and other sensitive information there. Someone may take the drive, but not the personal info.

    I just use a external drive formatted in EXT3, and for windows files i just install the Ext3 driver.

    I use an external NAS. It uses an encrypted Reiser filesystem. The NAS takes care of offering to the network NFS or SMB shares. In an outage, the shares unmount and require the encryption key to remount. This provides protection in case of theft of the drive. Per share I can provide either NFS and/or SMB services so it plays nice to Windows, Linux, and Mac. Putting stuff on it is as easy as posting on Slashdot except the whoa cowboy error messages.

  5. Re:Battery Life on Toyota Unveils Plug-in Hybrid Prius · · Score: 3, Interesting

    There are two kinds of battery life that needs work. One is related to range.. The 8 mile or 250 mile debate. Often overlooked is the battery life in charge discharge cycles. The only reason the Prius doesn't have a dead battery every 1-2 years like a laptop battery or cell phone or business 2 way radio is because they don't deep cycle them in normal use. A Prius seldom has a battery under 50% or over 80% charged.

    Heat, deep discharges, cell reversal, and overcharging is hard on batteries. The long range drivers do the worst.. Top the batteries off to get maximum range, run them till they go no more and repeat. Plan on buying new batteries every few years just like you do for your digital camera, MP3 player, cell phone, laptop, and other devices that get deep cycles often.

    I think the Toyota 8 mile range is to extend the battery life to 10+ years. It is not for maximum driving range at a high cost.

    Oh, and AMD isn't currently up on antitrust charges right now.

    I like your wording.. Like they are clean as a whistle. They are the ones suing. They are the ones dumping on the market even though their cost to produce is higher. Isn't that illegal? Nobody pressed charges simply because econnomic forces will end the price war as AMD runs out of money to sell below cost to capture market share.

    Intel as the economy of scale. They can and do sell at a profit at prices compeditors are unable to match as they have the hottest chips at the moment, have manufacturing capacity and effeciency to keep costs down. Part of Intel's winning the market is low defect counts so they have to throw away very little dead product. AMD went into the red with their under-pricing market dumping and cried foul.

    Intel is not dumping on the market at a loss to make up market share. They didn't do it when AMD had the leading products against the Pentium 4 line.

    Again, AMD does not have a clean shop in this Intel Anti-trust suit. Next time label it properly.

    The obvious way to conduct such a study would be to correlate the incidence of illness with the proximity to radio sources.


    I agree 100%. The difficulty is always background environmental pollution contaminating your test results. Think about it. Let's pretend the signal from the cell tower instead of an invisable radio wave is instead a visable light. If it is too strong the subject gets a sunburn from it or worse 2nd and 3rd degree burns depending on exposure (much like sunlight or exposure to a welding arc).

    Now remember that a tower is a 2 way communications device. Not only is there a little light from the tower that can be seen far and wide.. There are lots of other fires in the proximity sending signals to the tower. People stick these intense radiation sources right up against their bodies while glowing brightly. They also share same spaces with other users of the devices such as on the sidewalk, in cars, on busses, in offices.

    Now you wind up with a mild sunburn all over and a bad burn on the side of your face.. How much is realy from the glow on the tower?

    Get real people. Near field radio signal strength is a measurable field. Also note that the signal from a cell tower isn't like a street light sending brightness to the ground directly below it. It's built like a lighthouse sending a beam of signal horizontaly. Some spills to the ground near the tower just the same as you can see a lighthouse while standing near the lighthouse. The main intensity is sent for distance. That's what all the dBi numbers are all about in antenna gain. It's the same amount of power. It's that more of it is sent off the side instead of up and down in all directions.

    Many of these cell tower studies do not include time and peak weighted studies of tower field strength verses phone users field strength.

    How much RF effects is from your phone and not the tower?

    True, but it's undersize. The generators is a couple megawatts X10. The single rotary CPS size isn't specified, but from the manufactures site they list several sizes of units all under 1.5 MW. Most of the datacenter is NOT on critical power. From the size, it certanly isn't taking the support HVAC load. Since power was off for a couple hours and they didn't start generators for about 45 minutes, I'm sure any battery UPS'es died. Most racks overheat if powered up without cooling in under 15 minutes.

Just how much of the datacenter is not on critical power? Do the math. A CPS set is generaly sized smaller than any one of the generators. It carries essential emergency lighting, telcom, some "Critical servers" and little else. The rest of the site dumped with the outage after the little 10-20 minute UPS'es died. They waited 45 minutes before starting generators.

    Speaking of generators, if they upgraded servers (rack out, blade server in...) they could easly exceed the original design of N+1 on the generators.

    When shopping for a hosted datacenter, find out how much of the load is on "Critical Power". You may be dependant on battery UPS while waiting for the generators.

    They probably just didn't kick in. Had the same problem at Internap in Seattle a few years ago.

    Many datacenters didn't expect the growth they experianced. As a result, many UPS and generator sets are undersize or the entire load is not onboard. In some cases, the critical serviers are up to post the we are down page, but the HVAC system and main floor are down. What good is having a datacenter up if the building AC is down? Sometimes you are forced to shut down simply because the support AC is down and not on critical power. You can ride out a 20 minute outage without AC, but after an hour, it's at critical tempratures.

    On a related note, I also asked Stallman what he thought of the wedding photography industry. For those of you who don't know, typical wedding photographers cost over a thousand dollars, show up at your wedding to take pictures, and then make you pay through the nose for prints.

    Photographers will follow the money if nessary. If they advertise and get enough business, then they have no reason to change. If the money becomes educated and job hires a photographer with a contract for copyright including posting online for far away friends, putting into a slideshow on DVD for gifts, etc, then you will find photographers. The cost of advertising is shifted. Now you have to take bids and view potential canidates portfolios. This shift has started. As it becomes more popular, the traditional photographers will lose business to the new requirements. The shift is slow because of the entrenched model, but just like the Record industry, the shift will take time with lots of screaming and complaining in the meantime. Look for photographers lawsuits for wedding albums scanned and placed online for distant relatives. Then watch the public opinion and education to kick in.

    Free software hasn't replaced closed software yet. Open document standards hasn't replaced closed formats yet. It is unavoidable the movement has started and isn't going to reverse anytime soon. Even Microsoft who wouldn't touch an open document format with a 20 foot pole is learning to adopt or die. They have seen the handwriting on the wall. There is no other way. The photographers are not as much in the limelight, but the same movement is hitting them. More people are looking at their wedding photo contract with a critical eye. Many photographers are moving to middle ground to protect the big portion of their business expensive prints. The middle ground is many photographers now offer lower resolution (web friendly) photos as part of the package with permission to email, post, and put on DVD slideshows. The really nice prints are retained under the old model. This is much like what MS is doing. They accept ODF and make no bones it's the low resolution no features version, but also have this much nicer format you can also use, but to use it you need MS Office. Kerching!
