Some people, when confronted with a problem, think 'I know, I'll use regular expressions.' Now they have two problems.

Oh, i've read that paper long time ago (it's from early 90s if i'm not wrong). Stunning data structure.
I had not seen the video, so perhaps what follows is on it:
It turns out that not only skip lists are simple to implement, they can can also be "easily" changed to support multiple readers/writers. The structure (with n sized next pointer buckets) and the statistical distribution of bucket size allows for "localized" pointer management, resulting in more granular changes, making many inserts local. Compare this with AVL trees, where local insertions can alter large portions of the tree.
I've read (some time ago) that many high performance databases (Oracle, for instance) have changed to use this data structure for many operations because of it's better multi-threaded properties.
If my memory is not wrong, you can search ACM digital library and many papers on skip lists will pop out in the results, including multiple writers analisys.
Cool blog, BTW.

* use <pre>...</pre> to insert a plain code snippet.
* use <pre lang="lang">...</pre> to insert a syntax highlighted code snippet.
For example, <pre lang="python">...</pre> will insert Python highlighted code.
* use <code>...</code> to highlight a variable or a single shell command.
* use <a href="url" nospam>title</a> to insert links.
<a href="url" nospam>title</a>
* use other HTML tags, such as, <b>, <i>, <blockquote>, <sup>, <sub> for text formatting.

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
