		<title>Backup Software Cache Management</title>
		<description><![CDATA[So, normally, backup software is going to read 90+% of your machine&#8217;s hard drive, and push that data over the network to someplace else.
However, in the process of doing this, it is going to steamroll your operating system&#8217;s filesystem cache.
There are two improvements that can be had here, in my reckoning, and I&#8217;ve seen neither [...]]]></description>

		<title>Book Review: Security Warrior</title>
		<description><![CDATA[
Security Warrior by Cyrus Peikari and Anton Chuvakin
ISBN: 9780596005450
This book is an excellent introduction into the world of computer security. I was a bit surprised at the contents; the book features many more offensive techniques, like reverse engineering binaries, performing successful stack/heap overflows, attacks on a variety of server/network platforms, and defeating IDS/forensic technologies. I [...]]]></description>

		<title>Book Review: The Book of Xen</title>
		<description><![CDATA[
ISBN: 9781593271862
The Book of Xen: A Practical Guide for the System Administrator
Most Xen documentation on the Internet can be a tad focused on the single-computer, single-admin personal-use Xen administration case. This book, thankfully, is not. This is definitely the book to keep on your shelf if you require tips and tricks for setting up your [...]]]></description>

		<title>Installing a Gentoo VServer Guest on a Debian VServer Host on IA64/Itanium2 Platform</title>
		<description><![CDATA[There is like, zero documentation for doing this on the Internet. No one else wants to install Gentoo in a VServer guest on a Debian Itanium2 host? Lame.
This quick overview contains many things specific to my personal setup; therefore:

You will want to check your local gentoo mirror to see what the current ia64 tarball is.

		<title>Book Review: Network Warrior</title>
		<description><![CDATA[
ISBN: 9780596101510
This epically-titled O&#8217;Reilly book is a well-organized collection of network configuration tips, stories, and common &#8220;gotchas&#8221;, as told by a self-admitted grouchy old network admin to younger, wet-behind-the-ears network administrators.
The author, in a move uncommon to most networking manuals, just cuts to the chase and says what needs to be said. Everything is told [...]]]></description>

		<title>Undocumented Feature in IOS 11.2</title>
		<description><![CDATA[I found an undocumented feature in Cisco IOS 11.2.
The command &#8220;show interface description&#8221; exists in newer versions, so I typed it in out of habit. Even though it doesn&#8217;t tab-complete it, or know what that option to the sh int command is, it still works&#8230; Albeit badly, and it gives terribly formatted output (All on [...]]]></description>

		<title>Game of Life</title>
		<description><![CDATA[I got very bored in a far-too-easy networking class and ended up coding a very memory efficient version of Conway&#8217;s Game of Life.
Of note, it uses bit-twiddling/bit-packing to access individual bits on byte-accessible memory for the gameboard, and it uses a sort of buffer-thing to further reduce memory usage, rather than push temporary changes into [...]]]></description>

		<title>NFS Blocksize Optimizations</title>
		<description><![CDATA[I decided to redo the NFS setup I previously had on my ol&#8217; Itanium2 machine.
How to test to see which NFS block size is right for your setup:

#Testing write speeds:
mount hostname:/remote_folder/ /mnt/local_folder/ -o rw,wsize=1024
time dd if=/dev/zero of=/mnt/local_folder/write_test bs=16k count=16k
umount /mnt/local_folder/
#Testing read speeds:
mount hostname:/remote_folder/ /mnt/local_folder/ -o ro,rsize=1024
time dd if=/mnt/local_folder/write_test of=/dev/null bs=16k
umount /mnt/local_folder/

Go through and change wsize [...]]]></description>
