Tech: May 2008 Archives


I was one of the judges for UC Berkeley School of Information’s 2008 Master’s final projects competition this afternoon, helping pick the best among the projects in the information systems implementation track. We saw several really interesting student projects. Most of the presenters held up under the heat and stress, and I enjoyed seeing the level of attention to detail that the best project teams brought to the table. Thankfully, the judging wasn’t all that difficult; Peter Merholz, Jeff Ubois, and I came to a decision pretty quickly. The winning project team will be informed during their commencement ceremony tomorrow.

Seeing the students getting ready to graduate was bittersweet. I took a leave of absence from the school’s masters program nine years ago. Getting into the program, then called the School of Information Management and Systems (SIMS), was all I wanted to do with my life. I was admitted as part of the second entering class, but eventually left school to try to launch a startup around a class project that was gaining traction online. Though it was clearly the right choice to make, I still feel like I gave up on something really important. I’m glad to be able to be a part of the school’s extended family, through links with past professors, fellow alumni, and current staff.

I’ve made a few tiny contributions to open source tools over the years, but nothing significant. I recently uploaded Business::LCCN, my first public Perl module, and open source contribution under my own name.

Library of Congress Control Numbers, or LCCNs, are codes that point to book records in the US Library of Congress. I’ve been encountering LCCNs while working on a personal book cataloging project. There are some weird ins and outs to dealing with older LCCNs; I had to contact the Library of Congress to learn some of the obscure details that aren’t publicly documented. Business::LCCN parses and manipulate LCCNs, taking these special rules into account, abstracting away most of the complexities.

Perl modules uploaded to CPAN get run through a variety of systems:

I’ve really enjoyed being able to write some code, and get so many other services for free.
