Gadgets: Ginormous storage in Tiny space

From Gizmodo, Western Digital released a laptop 2.5" hard drive today with a whopping 320 GB! Drives are pretty reliable these days, but this just seems a little scary to me... imagine 300 GB of your family photos disappearing due to a hardware failure... ( see last article ).

Backup, backup, backup...

Tech: Parallels 3.0 causing NMAP errors?

I don't have any definitive proof, but it seems that installing Parallels 3.0 causes certain networking tools to break. I've noticed nmap 2.403 on my machine is broken since I upgraded to Parallels 3.0. I didn't suspect Parallels until I found another user ( dcortesi.com ) complaining about the same issue, as well as similhttp://www.blogger.com/img/gl.link.gifar reports on Parallels' forums regarding Cisco VPN client.

Whenever I run nmap I would get the following error:

Starting Nmap 4.03 ( http://www.insecure.org/nmap/ ) at 2007-06-15 13:36 EDT
getinterfaces: Failed to obtain MAC address for ethernet interface (fw0)
QUITTING!

Following similar resolution procedures for the Cisco VPN client ( uninstall Parallels, Cisco VPN, then reinstalling Parallels before Cisco VPN client ), I decided to reinstall nmap on my system. After downloading, compiling, and installing the latest version of nmap the issue was fixed.

1) Download latest Nmap version
2) Unpack the archive
3)
cd nmap-4.21ALPHA4
./configure --prefix=/opt/local
make
sudo make install

Correction: should configure with the following options:
./configure --prefix=/opt/local --without-nmapfe
nmapfe is the GUI interface that uses GTK+ and X11 which we typically don't use on OS X
