  3. Speaking of having to using a GUI for OSX Server, here’s a blog post about somebody who tried to use all command-line utils for a day.

    The list of apps is a pretty standard set for most UNIX junkies (and really doesn’t cover *anything* about OS X), but there’s a gem or two in there.

  4. RE: RAID 6

    Okay – that’s somewhat simple. RAID 5 uses parity, requires at least 3 drives and capacity is n (number of drives) – 1.

    RAID 6 uses double-parity, requires at least 4 drives and has a capacity of n-2. The double-parity calculations will cause a performance hit and this white paper doesn’t really describe what happens when you’re missing half your data and want to rebuild. (For example, drives 1 & 2 fail, disk 3 & 4 contain just parity data – how does it rebuild drives 1 & 2 – think about an 8 drive array when you, though). I know it works – I just want to understand how. ;-)

  5. From the home user I think DirectX 10 a big thing with Vista. Games drive a huge portion of the market and while this may not make Vista the thing to have now, I think that later this year when DirectX 10 games and DirectX video cards are out Vista sales may also start jumping.

  6. Great point Ben, I’m not much of a gamer so that didn’t hit me. I have heard that from other people who are intending to build the ultimate (no pun intended) Media Center box, although, I’m not clear on what the key advantage is to having a video card support this for media purposes…
