		<title>Basic Emacs Tutorial</title>
		<description><![CDATA[In my last post, I wrote about how I had to write a guide to using a piece of software for a class.  Well, I had to do another one, but this time it was individually rather than in a group.
So, I wrote a guide on how to do some basic tasks in emacs.

		<title>Fedora 10, Subversion, and WebSVN</title>
		<description><![CDATA[Justin and I recently wrote a guide to installing Subversion for a class that we&#8217;re taking.  It&#8217;s a pretty simple process and we&#8217;ve tested it twice now, but if you try it and something it unclear/doesn&#8217;t work, let us know.

		<title>Firefox, Ubuntu, and Spell Checking</title>
		<description><![CDATA[I just noticed that my version of Firefox 3.0.8 running in Ubuntu 8.10 had en_AU as it&#8217;s default spell checking dictionary.  Is this true for anyone else?
The only reason I noticed this was because Firefox was marking words such as &#8220;organization&#8221; and &#8220;enrollment&#8221; as being spelled wrong.
If anyone wants to look at their current [...]]]></description>

		<title>Dot Name</title>
		<description><![CDATA[I had some trouble with my domain recently where it was pointing to a parked page.  This was because my hosting provider didn&#8217;t update my registration in time, but this has all been resolved now.
This dilemma got me thinking and I decided to purchase a dot name domain.  ryan.lewis.name now points here!

		<title>Fix &#8220;Unexpected clusters per mft record (-127)&#8221;</title>
		<description><![CDATA[I encountered this error yesterday after trying to fix some Windows bootloader issues in Ubuntu with ms-sys.  Needless to say, I just created more issues and eventually couldn&#8217;t even mount my Windows partition from Ubuntu, as this would happen:

# mount -t ntfs-3g -o force /dev/sda1 /mnt/win
Unexpected clusters per mft record (-127).
Failed to mount '/dev/sda1': [...]]]></description>

		<title>Zero-Knowledge and You: A Beginner&#8217;s Guide to SPHiNX &amp; Challenge-Response Protocols</title>
		<description><![CDATA[This is a paper that Josh Hollenbeck, Pat Wilbur, and myself wrote last semester for Cryptography.  Just posting it for anyone who wants to read it.

We present a method for zero-knowledge, hash-based challenge-response network authentication in lieu of transmitting a password across the network. Zero-knowledge protocols, like our method, offer authentication alternatives to prevent [...]]]></description>

		<title>Random Numbers and NTL</title>
		<description><![CDATA[According to its website, the Number Theory Library (NTL) is a:
high-performance, portable C++ library providing data structures and algorithms for manipulating signed, arbitrary length integers, and for vectors, matrices, and polynomials over the integers and over finite fields.

		<title>Samsung LN32A450, nVidia Drivers, and Ubuntu</title>
		<description><![CDATA[I just recently purchased a Samsung LN32A450 television and wanted to use it as a monitor.  I figured that it shouldn&#8217;t be too hard, just plug in my computer to it&#8217;s VGA port and then change the resolution.  
But, when are new things ever easy?
To make a long story short, I had to [...]]]></description>
