Here is how to set up a Mac, running OS X Client 10.5 or later, as a PXE boot server.  We will configure OS X’s built-in DHCP, TFTP, and NFS servers, start the servers, and put the client boot files in place.  (The NFS server may be optional, depending on the operating system we are booting.)

You’ll need the Mac, a PXE-capable PC, and an ethernet cable.  Some steps will require being logged in as an administrator on the Mac.

We’ll boot Debian Live on the client PC as an example.  We’ll show a regular setup with NFS, an alternate setup without NFS, and how to uninstall.

Regular setup (with NFS):

1. Connect the Mac and the client PC with the ethernet cable.

2. On the Mac, in System Preferences > Network, click “Ethernet” and enter the following settings:

   Configure IPv4: Manually
   IP Address: 192.168.1.1
   Subnet Mask: 255.255.255.0
   (All others can be left blank)
   

   Note the status may read “Cable Unplugge …

Forget the Izod alligator or the usual polo pony for Polo shirts. Polo is finally going where no Polo shirt has gone before — straight into the final frontier. They are finally taking Trekkies seriously (okay, as seriously as anyone can), and turning the uniform shirts from the original series into business casual. How long before this fashion statement turns up on the Big Bang Theory? I’m envisioning Sheldon in science blue even as I write.

iOS: We’re fans of the Wake N Shake alarm clock because it really forces you to get up and out of bed by making your vigorously shake your phone before the alarm turns off. If you’ve wanted to give this evil wakeup call a try, you’ve always had to drop a couple of dollars, but for the next few days the app is free.

The sale is to celebrate a host of new features, including a complete redesign that makes Wake N Shake easier to use as a whole. Of course, the basic premise of the app, that you have to shake your phone vigorously before the alarm turns off, remains the same. Wake N Shake is certainly one of the more sadistic apps out there, but if you struggle to get up in the morning it’s worth grabbing now while it’s free.

Blade steel is the heart of any good knife, and yet for a lot of folks, wading in to metallurgy is not a fun or profitable venture.  For steel junkies, blade steel is the very reason to buy a knife, but for the rest of us, it’s all just an alphabet soup of terms.  What[…..]

MySQL fulltext search (FTS) is old and well known. It has a simple setup and requires only small changes for querying. For many people it’s more than enough to provide fulltext search. So, here’s the question: why add a new variable – Sphinx – into the system when the database already has the basic functionality? […]

Thanks to unsupportive seats you have to sit in for hours, flying is often literally a pain. You can reduce your chances of getting a sore, achy back on your next flight by bringing along an inflatable beach ball.

Physical therapist Doug Kelsey writes on the My Itchy Travel Feet blog that the adjustable beach ball is perfect for lumbar support:

Because the beach ball is filled with air, it allows you to move in your chair which in turn, moves your spine just enough to keep it from getting stiff.

• Put a very small amount of air in the ball (once you’re in flight, the pressure change will increase the pressure in the ball so you don’t need much air).
• Place the ball in the small of your back.
• Increase or decrease the amount of air to your comfort level.
• About every thirty minutes, move the ball either up or down an inch or two.
• While in flight, periodically move side to side, forward and back for about a minute—kind of a small rocking motion of your trunk on the ball.
• When you’re done with the flight, deflate the ball and store for later use.

Bonus: You’ll have something to toss around if you head to a beach or park on your vacation.
