  • Do strimmers hold more promise than they deliver?

    This looks like the closest match over here:

    I've had a few petrol based so maybe its time to try something new ..

    I have seen some newer cordless trimmer that use Lithium Batteries or are higher voltage.  They might be more compelling:

    I have also seen similar Lithium Battery models from the other major power tool companies at our local Home Depot.

     

    For me personally, I use some other tools that share the same battery (http://www.blackanddecker.com/ProductGuide/CategoryOverview.aspx?cPath=1498.4945).  So I probably wouldn't upgrade my trimmer unless I was upgrading everything.  Maybe once B&D comes out with Lithium equivalents of all of them.

     

    As I said before, the battery power definitely has it's limits.  When the battery gets low, it will start to bog and slow down.  I only use it for a total of <30min after mowing to tidy up.  If I had a bigger yard or fancy landscaping to maintain, I would probably use a gas trimmer.

  • Do strimmers hold more promise than they deliver?

    Never heard the term "strimmer" before.  I've heard it called "weed whacker" and "string trimmer".

     

    I pull mine out probably every other time I mow.  I use it to trim the grass right at the edge of the house foundation, in that <1inch gap the mower won't touch.  We also have a kid's play set in the back yard that I have to trim around.  (Eventually I want to put down mulch or some kind of edging around the house so I don't need to do this.)

     

    Probably the biggest use for my trimmer is for along the edge of the sidewalk and driveway.  My trimmer converts into an edger by spinning the head around so it trims vertically.  It does a great job giving the sidewalk and driveway a "fresh from the barber" look.

     

    Mine feeds the string automatically when it gets to short.  Never had to even think about it.  Crud, now I wonder how much string is left in it.

     

    This is the model of trimmer I have, BTW.  http://www.blackanddecker.com/ProductGuide/Product-Details.aspx?ProductID=23463

     

    The battery power definitely has its limits, but it is capable enough for my lot (0.35 acres).  I have a few other Black and Decker yard tools that use the same batteries, so it is easy to interchange, and I always have a spare fully-charged battery ready to go.  The battery is nice because I don't need to drag a cord around, and it doesn't need the care/maintenance that a gas engine needs.

    Isn't Skype encrypted?

  • Skype wants your BIOS

    Welcome to the real world.  MAC addresses usually are unique, but not always.

    1. Most OSes let you spoof MAC addresses.

    2. Most ethernet controller chips let you modify the MAC address at runtime (a requirement for #1).

    3. Many broadband routers allow MAC address spoofing.

    4. Some ethernet controller chips have a bug where some of the MAC address bits will periodically change.  This bug was present on an extremely popular PCI Ethernet card sold at retail chains across the country.

    5. Some el-cheapo network card vendors will recycle MAC addresses, rather than purchasing a new block of numbers.

    6. Early Sun Microsystems workstations had dual ethernet ports, but allocated MAC addresses PER WORKSTATION, not per port.  So, there were 2 ethernet ports with the same MAC address.

    Not sure if this answers the question, but MAC addresses are not universally unique.

  • XP service pack 2 and mup.sys

    Even if you reinstall, you still haven't isolated the cause of the problem.

    The 0x7B stop code and the corrupt registry file (\system32\config\system) point to a failing device in your storage subsystem.  Check your hard disk and IDE cables.

    Your hard drive maker probably offers a drive test utility as a free download.  Get a copy and run it.  Make sure there are no bad blocks on the drive.

    Also, double check your IDE cables.  Make sure they are all 80-conductor.  Also check cable lengths.  Any IDE cable longer than 18" is bad and should be thrown out immediately.  Likewise for those sliced/narrow IDE cables.

    It may also be your IDE controller, especially if you are using a cheapo IDE RAID controller.

    Another oustide possibility is that it's bad memory.  It may be worth running an overnight cycle of Memtest86.

  • Windows Explorer security question

    rjdohnert wrote:
    If I am running an alternative shell and not Windows Explorer and Im using a different Filemanger than Windows Explorer, would I still be as vulnerable as users who are running it as their default shell?


    It depends.  Some alternative shells hook into the same libraries of Windows as Explorer.  If a vulnerability is found in one of those libraries, you're just as vulnerable.

    You'd have to look at them on a case-by-case basis.

    Use depends.exe to look at DLL dependencies for Explorer (look at explorer.exe).  Then, compare it to your alternate shell of choice.  If you see any common dependencies, then a vulnerability in one of those DLLs could affect both.

    Is there any causes of System (not System Idle Process) running at 90-100 for extended periods of time?


    Most likely it's a buggy driver.  USB devices are particularly notorious for having drivers with a high CPU load.

    I suggest that you shut off or remove devices one at a time until you find the culprit.  Start with USB devices.

    What exactly do you base that on?  I'm not trolling, it's a genuine question.

    Have you reviewed code that he has written?

    Have you discussed software architecture with him?

    Your previous post does not answer my question.

    How will ditching backward compatibility make my life better?

    All it will do is require me to fork out a large sum of money to upgrade all of my applications.
